OPEN-DRIVE COMPRESSORS

These compressors are designed to operate with Refriger-

ants 12, 22, 134a, 502, or 507/404A. See Table 1.

Operating Requirements —

a reciprocating compressor depends on 3 fundamental requirements:

1. Prevention of excess discharge temperature.

2. Adequate compressor lubrication.

3. A clean and dry system.

Discharge Temperature —

discharge valves within the cylinders is a controlling factor. Some cooling of the discharge gas occurs before reaching the discharge stop valve, thus when water-cooled heads are used, this cooling is greater than it is without water cooling. To prevent excessive temperature at the compressor discharge valves, the following temperatures, when measured immediately following the discharge stop valve, must never be exceeded:

For nonwater-cooled heads . . . . . . . . . . . . . . . . . . 275 F max

For water-cooled heads . . . . . . . . . . . . . . . . . . . . . 250 F max

The approximate discharge gas temperature can be found

by using the following equation:

T2 = T

Where:

= Discharge temperature, F absolute

T1= Suction temperature, F absolute (including

superheat)

= Discharge pressure, psia

P1= Suction pressure, psia N = Compression exponent of the gas (see T able 2)

The value of compression exponent “N” depends upon the properties of gas compressed, degree of cooling in compressor jacket, leakages, etc.

To simplify discharge temperature calculations, the preceding formula may be stated in the following form:

Although exponents are shown for high compression ratios, these are for information only. Rating tables define allowable selection and operation limits.

High Compression Ratio —

Avoid compressor operation at compressor ratios exceeding those covered in the rating tables. For operating conditions outside the limits shown in these tables, use 2-stage compression. Care must be taken to prevent the compressor from pulling down to levels outside the rating tables.

Suction Gas Superheat —

Excessive suction gas superheat will result in abnormally high discharge temperatures, which must be avoided. When using Refrigerants 12, 134a, 502, and 507/404A it is recommended that the actual suction gas temperature not exceed the v alues in Table 4.

Keeping Liquid Refrigerant Out of Compressor —

liquid particles in suction gas must be kept out of the compressor by proper system design and compressor control. Under operating conditions, presence of unevaporated liquid refrigerant in the compressor tends to break down oil film on cylinder walls, resulting in increased wear and loss of machine capacity.

refrigerant absorption can result in a refrigerant and oil mixture in compressor crankcase. Gravity flow can be prevented by the use of recommended loops, but thermal action and the absorption of refrigerant by lubricating oil cannot be prevented by piping design.

For the above reasons, the compressor must be controlled

during idle times by one of the following methods. MINIMUM PROTECTION — The minimum protection that

Carrier will allow is shown in Fig. 1. Actuated control thermostat energizes crankcase heater and closes the liquid line solenoid valve simultaneously. With crankcase heaters energized, the crankcase temperature is always held above shutdown temperature in the evaporator coil and there will be no refrigerant migration to the crankcase.

With this type of control, a control relay is required and crankcase heaters have to be energized when the compressor is not operating.

The control relay coil is locate d in parallel with the liquid line solenoid, and a normally open control relay contact is added in series with the compressor starter and other auxiliary safety devices.

When the thermostat calls for cooling, the solenoid valve opens and control relay is energized. This closes the relay contact and, if other safety devices are in their normal position, compressor will start. Simultaneously, the normally closed compressor auxiliary contact will open, removing crankcase heaters from the circuit.

When the thermostat is satisfied, the solenoid will close and control relay is deenergized. This opens relay contacts and compressor stops. This causes compressor auxiliary contacts to close, energizing crankcase heaters.

Specifications are sometimes written to call for a degree of protection greater than that afforded by the standard method. If this is the case, either single pumpout or automatic pumpdown control may be required.

protection against liquid refrigerant accumulating in the compress or cr an kc as e.

Do not use pumpdown control with dry expansion coolers as it may cause frost pinching or freeze-up. Do not use pumpdown control with dry expansion coolers if it is anticipated that there will be short bursts of system operation, as this will result in a gradual loss of oil.

SINGLE PUMPOUT CONTROL (Fig. 3) — Pumpout control is not as effective as pumpdown control in keeping liquid refrigerant out of the crankcase. However, it is usually satisfactory when used with crankcase heaters if pumpdown is not acceptable.

Single pumpout control is similar to pumpdown control, except that a pumpout relay is added, a normally open c ompressor auxiliary contact is necessary, and energizing of crankcase heaters is required at end of each operating cycle.

AUTOMATIC PUMPDOWN CONTROL (Fig. 2) — Pumpdown control is the most effective means of compressor control in keeping liquid refrigerant out of the crankcase on system shutdown.

In the basic pumpdown control sequence, the thermostat controls the liquid line solenoid valve to stop or start the flow of refrigerant to the evaporator as required.

The pumpdown control system permits compressor cycling if a system malfunction allows low side pressure to rise. Although this cycling is sometimes considered objectionable, it illustrates need for maintenance attention and provides positive

With single pumpout control, when the thermostat is satisfied, the compressor pumps down once and stops. It starts again only when the thermostat calls for cooling. In pumpdown control, the compressor cycles only on the low-pressure switch, regardless of thermostat demands.

Do not use pumpout control with dry expansion coolers as it may cause frost pinching or freeze-up.

MANUAL PUMPDOWN — The compressor may be controlled manually without the use of pumpdown, or single pumpout control, and without crankcase heaters, provided t he system is at all times under control of a qualified operator. The operator will pump down the system by use of manual valves and will keep liquid, suction and discharge valves closed when the machine is not operating.

Compressor Capacity Notes

1. Compressor capacities are based on 1750 rpm and 15 F subcooling for all unit sizes and refrigerants.

2. Multiplying factors for other rpm:

RPM 1450 1160

Capacity

Bhp

0.835 0.674

0.798 0.602

See Multiplying Factors chart on page 31.

3. Liquid subcooling greater than (less than) 15 F incorporated in ratings increases (decreases) system c apacity by

/2 of 1% for each degree of subcooling. When correcting

for subcooling, brake horsepower does not change.

4. Refrigerant temperatures shown in Table 5 are saturation temperatures corresponding to pressures indicated at compressor. Actual gas temperatures are higher because of superheat.

5. Capacities are based on actual suction gas tempera-

tures to compressor of 65 F for R-12, R-134a, R-502, and R-507/404A. (This assumes superheat is obtained from liquid suction inter changer or in evaporator.)

Capacity corrections, other than for rated suction gas temperatures, may be obtained by using Rating Basis and Capacity Multipliers Tables 6 and 7. Refrigerant-22 suction gas superheat for ratings (15 F) normally occurs because of expansion valve operation and line losses. Therefore, R-22 ratings can be used without adjustment.

An alternate method for capacity correction is to run the Carlyle Selection program to obtain performance ratings at other than 65 F return gas temperature.

Compressor ratings and capacities are included in T ables 8-12.

Compressor Features and Accessories

WAT ER - COOLED HEADS AND OIL COOLERS — Water cooled heads are typically not necessary for R-12 or R-134a applications within the range of compressor ratings shown in this publication. For R-502, or R-507/404A at the shaded conditions shown in the compressor ratings tables, water-cooled heads may be necessary, if the discharge temperature is greater than 275 F. The discharge temperature will increase with return gas temperature.

When operating conditions are such that suction gas becomes highly superheated and/or the compression ratio is high, it is recommended that an oil cooler be used on the compressor. An oil cooler is required on increased displacement compressors (5H46, 66, 86, and 126) on installations where compressor(s) can be subjected to extended periods of continuous, fully unloaded operation. These periods do not afford sufficient removal of compression and friction heat, and could result in overheating of the running gear, shaft seal and crankcase oil. The addition of an oil cooler removes excessive heat, ensuring increased life expectancy of compressor and components.

Extended periods of continuous, fully unloaded operation will occur usually on variable-volume installations that use hot gas bypass to maintain conditions under all load situations. Without hot gas bypass, the compressor will usually cycle on the low-pressure switch (or temperature controlling device) giving time for seal, oil and crankcase to cool.

On multiple-compressor installations where all units are manifolded into one refrigerant circuit, the controls should be designed to cycle off compressors at light loads to put maximum output on the still operative compressor. It is always desirable for the compressor to operate with as many cylinders as possible in loaded condition.

Water-cooled oil cooler package is available from the factory and is easily field installed on all 5 Series compressors. Refer to 5F,H Compressor Ratings to determine when oil coolers are required. These ratings, however, do not indicate oil cooler requirements during periods of extended continuous operation under fully unloaded operation. This should be determined on individual job basis.

W ater flow through compressor heads (and w ater-cooled oil coolers, if used) must be shut off when the compressor is not running to prevent refrigerant vapors from condensing at the compressor during OFF cycles. For this purpose a solenoid valve is recommended in the water supply line to compressor heads.

Values listed in Table 13 assume a water temperature rise of 30 degrees. Oil cooler and water-cooled heads must be piped in series, with the oil cooler first. Leaving water temperature should be between 100 F and 120 F, w ith 120 F being maximum allowable temperature. Maximum working pressure for water-cooled heads is 125 psi.

NOTES:

1. Shaded ratings require an oil cooler when using a liquidsuction interchanger, or when 50 degrees of superheat is exceeded.

2. An oil cooler is recommended for all long stroke compressors (5H46,66,86 and 126).

3. Refer to Table 5 for Total Heat Rejection.

NOTES:

1. Shaded ratings require water-cooled heads, if the discharge temperature exceeds 275 F.

2. An oil cooler is recommended for all long stroke compressors (5H46,66,86 and 126).

3. An oil cooler is required when SST is below –20 F.

4. Refer to Table 5 for Total Heat Rejection.

SAFETY RELIEF VALVES — All 5H compressors are equipped with built-in safety relief valves that are factory set to relieve from discharge to suction side of the compressor at a pressure differential of 350 psi.

Safety relief valves that re lieve at a 400 psi pre ssure differential are factory installed on the 5F60 compressor but are not available with smaller 5F compressors.

SUCTION STRAINERS — Each 5F,H compressor is equipped with one or 2 suction strainers located in the suction manifold. On new installations, felt filters should be used in suction strainers to trap foreign material left after installation. After 50 hours of use, these felt filters must be removed. See 5F ,H Installation Instructions for further details.

OIL SAFETY SWITCH — An oil safety switch is provided as standard with all compressors except 5F20 and 5F30. This switch is optional equipment on 5F20 and 5F30 compressors. This switch will shut off the compressor before high oil temperatures or lack of oil causes loss of oil pressure which can result in compressor failure. As a safety feature, this switch must be reset manually after cutout.

OIL SEPARATORS — Oil separators in the hot gas discharge line are not recommended for general use. However, there are systems where protection afforded by a separator is desirable, notably systems employing flooded evaporators or refrigeration systems with long system piping. For a more complete discussion see Carrier’s System Design Manual.

CRANKCASE OIL HEATERS — Crankcase oil heaters are available for all 5F,H compressors. Heaters keep the crankcase warm during off cycles and thus minimize refrigerant absorption in the oil. Crankcase heaters are recommended for CFC or HCFC refrigerant applications and are required for HFC refrigerant applications with POE lubricants. Refer to the 5F,H Installation Instructions for installation and wiring.

INTERCONNECTION OF COMPRESSORS — All 5F,H compressors are furnished with removable handhole cover plates on each crankcase. When field interconnection is desired on 5F40 through 5H86 compressors, cover plates can be removed and replaced by spe cial cover plates with tapped open ings. These tapped cover plates have connections for both oil and gas equalizing lines. For interconnection of 5F20 and 5F30 compressors, use the opening for the oil sight glass (see 5F,H Installation Instructions). Cover plates for interconnection are standard equipment on 5F120 and 126 compressors.

Many refrigeration systems utilize oil management components such as an oil separator, oil reservoir and floats. The oil level control float an be installed in the sight glass connection in the 5F ,H handhole cover plate.

VIBRATION ISOLATORS — A standard vibration isolation package is available for each 5F,H compressor . This consists of a standard rubber-in-shear and compression type mounting that gives an average static deflection of approximately

/8 in. and

provides reasonably good vibration isolation at 1750 rpm.

The use of vibration isolators is recommended for al l compressor and condensing units because:

1. Transfer of vibration to structure is reduced when the units are installed on upper floors.

2. They limit drive shaft misalignment on installations where units are bolted to an uneven concrete floor.

Vibration isolators giving approximately

/8-in. deflection are available for superior isolation or if the compressor is run at slower speeds. Tables 14 and 15 provide an estimated weight distribution on legs of a compressor or condensing unit when used with a normal horsepower motor.

MUFFLERS — Four standard mufflers cover the entire model range of 5F,H compressors. It is recommended that these mufflers be installed when compressors are used with remotely located water-cooled or evaporative condensers.

Mufflers are not usually necessary with smaller 5F compressors and their use is recommended only when quiet operation is required.

Each piping package to convert 5H compressor units to condensing units includes a standard muffler of appropriate size.

Pressure drop through mufflers is about

/2 psi at 40 F suction and 105 F discharge with following loadings: 5 tons with 5F20 muffler, 15 tons with 5F40 muffler, 35 tons with 5H40 muffler and 100 tons with 5H120 muffler.

For all 5F,H compressors, a pressure-type cylinder unloader is used. On 5F20 and 5F30 compressors, the capacity control valve is external and on 5F40 through 5H126 compressors the valve is located internal ly. On all 5F,H compressors, capacity reduction is in response to suction pressure.

The cylinder unloading mechanism is powered by a compressor force-feed lubricating system. This feature assures unloading of all controlled cylinders at starting regardless of

the position of the capacity control valve, since suction valves will be held in open position until the lubricating oil pressure reaches its normal operating level. Refer to Fig. 4 for cylinder unloading sequence.

An external adjusting stem is provided to set control point and maintain desired suction pressure. The control point is adjustable from 0 to 85 psig suction pressure. Differential over the complete range at any temperature level is 10.7 psig with Refrigerant 22 and Refrigerant 502. A 7-lb spring (for use on 5F40 and larger units) is furnished with the compressor which, when used, results in an adjustable control point from 0 to 50 psig with a 6.8 psig range. Insert a spring in the capacity control valve when R-12 is used. See Fig. 5.

With this arrangement, suction pressure will not drop below the control set point minus the differential within range of capacity steps since the compressor will unload to balance its capacity with evaporator load.

Power elements and valve l ifting mechan isms are identi cal on all 5F,H compressors. However, when using capacity control, various methods are used to activate the power elements.

See Table 16 for unloading steps and power requirements at each step.

5F20 AND 5F30 (Fig. 6) Major Elements of Control Systems:

1. Capacity Control Valve: Function is to raise or lower oil pressure from oil pump in response to refrigerant suction pressure.

2. Power Elements: Function is to supply power necessary to operate valve lifting mechanism. It is modulated by the capacity control valve.

3. Valve Lifting Mechanism: Consists of a sleeve and push pin assembly around each controlled cyli nder, designed to hold the suction valve open, or to permit the valve to remain in a normal operating position depending on its actuation by the power element.

5F40 THROUGH 5H86 (Fig. 7) Major Elements of Capacity Control Systems:

1. Capacity Control Valve: Function is to raise or lower the control oil pressure to the hydraulic relay piston in response to refrigerant suction pressure. Increase in suction pressure increases control oil pressure in the hydraulic relay.

2. Hydraulic Relay: Function is to feed lubrication oil from the oil pump at full pressure in sequence to one or more power elements. Relay is activated by control oil pressure from the capacity control valve.

3. Power Element: Supplies power to operate the valve lifting mechanism.

4. Valve Lifting Mechanism: Consists of a sleeve and push pin assembly around each controlled cyli nder, designed to hold the suction valve open, or to permit the valve to remain in a normal operating position depending on its actuation by the power element.

Principle of Operation of the System

— A decrease in suction gas pressure, which necessitates a decrease in compressor capacity, causes the range spring to open the capacity control modulating valve. This allows control oil to relieve from the hydraulic relay and thus reduces control oil pressure in the relay. With reduced control oil pressure, the spring in the hydraulic relay moves a piston and thus lubrication oil from the oil pump is prevented from flowing to a particular deactivated power element. This relieves oil pressure from the power element allowing the spring in the power element to move the lifting fork and unload the cylinder. An increase in suction pressure reverses action and loads cylinders.

Fig. 9 — Pneumatic Compensation

pacity control s ystem is slightly differe nt from the system on 5F40 through 5H86 compressors. Unloaded starting and capacity reduction is obtained by holding open the suction valves of a number of cylinders. For capacity control purposes, a suction-pressure-actuated capacity control valve pilots a hydraulic relay that loads or unloads cylinders in pairs.

Major Difference from the 5F40 through 5H86 Capacity Control:

1. The hydraulic relay design provides a wider pressure differential between cylinder cut-in and cutout points. The relay is a small, easily removed ca rtridge rat her th an an integral part of pump end cover.

2. The surge chamber on 5H120 and 5H126 is an integral part of the bearing head casting.

PNEUMATIC COMPENSATION OF COMPRESSOR CAPACITY C ONTROL — Adding a control air line to the external pneumatic control connection permits pneumatic resetting of the control point in accordance with changes in operating conditions. Each pound of change in air pressure resets the control one pound in the same direction. Thus, a onepound rise in air pressure will cause unloading to begin at a suction pressure one pound higher than the original control point, etc. Figure 9 shows a typical pneumatic control arrangement. All components and installation instructions are field supplied.

— Dual pressurestats are furnished with all 5F,H compressors. The y are often referred to as high- and low-pressure cutouts. Their function is to cut the circuit to the holding coil of the compressor motor starter when pressure setting limits are exceeded.

The high pressurestat has an operating range from 50 to 450 psig with a differential range from 170 to 235 psig (adj). The low pressurestat has an operating range from 20 in. Hg to 60 psig and a differential range from 60 to 90 psig (adj).

Pressurestat settings should be adjusted on the job to meet particular operating conditions for which the compressor(s) have been selected. Directions for setting these pressurestats are in the 5F,H Installation Instructions.

Permanently Unloaded Cylinders drive compressor with its cylinders permanently unloaded requires field modification. The 5F60, 5H40 and 5H60 compressors can operate with one cylinder unloaded; 5H80 and 5H120 compressors can operate with 2 cylinders unloaded. Compressors are modified by removing the suction valve and suction valve springs from the cylinder(s) shown in Fig. 4.

ELECTRIC SOLENOID VALVE CAPACITY CONTROL — Closer control of a conditioned space or medium can be realized by activating the cylinder unloaders directly in response to an external step controller activated by solenoid valves. A temperature sensing control ler activates the electric solenoid valves. Refer to Fig. 10 for an operating concept using an external electric solenoid-type capacity control. All components external to the compressor must be field supplied. Modifications required for standard sequence are as follows:

5F20 and 5F30 Compressors required to the 5F20 and 5F30 compressors. See Fig. 4 and 11. Securely attach a ported solenoid valve to compressor to minimize line vibration. Connect a pressure flexible hose, KA73RR025, between the compressor and solenoid valve.

5F40 and 5F60 Compressors

1. Remove the capacity control handhole cover. Remove the hydraulic relay and all tubing. As shown on Fig. 12, drill and tap 3 holes on the bottom side of the cover and 2 on the front. No hole is required at point A on 5F40 compressors. Plug 5 cover holes that connected cover to the relay. Plugs are

2. Install cover with a new cover gasket 5F40-1042.

3. Mount solenoid valves on a sturdy bracket attached to the handhole cover using stud bolts on the compressor.

4. Connect external oil lines as shown in Fig. 12 and 13. Steel tubing and compression fittings are recommended.

5H40 Through 5H86 Compressors 5H40 through 5H86 built after Serial No. G103460 (July 1971) may be modified for electric solenoid unloading without additional machining. Proceed as follows: (See Fig. 4, 13, 14, and 15).

1. Remove pump end cover only from the compressor .

2. Using the pump end cover gasket (Part No. 5H40-1423) as a guide, make a blank metal disc ( making holes for bolts only.

3. Reinstall the pump end cover using 2 new 5H40-1423 gaskets, one on each side of the blank disc. This isolates the capacity control cover.

4. Mount solenoid valves and run oil lines.

5. To minimize vibration, mount the valves on a bracket attached to the compressor.

CAPACITY CONTROL MODIFICATIONS FOR HEAT PUMP APPLIC ATIO N — Where 5F40, 5F60, and 5H compressors are used in refrigerant cycle reversing heat pump applications, it is usually necessary to modify the standard capacity control arrangement to satisfy unloading requirements. On summer cycle, the compressor is required to unload as circulating water or air temperature drops. During winter cycle, the control works in reverse, so that the compressor unloads as the circulating water or air temperature increases. It is necessary for the compressor to unload in response to e ither a summer or winter temperature-sensing device, depending on the particular cycle in operation.

Where summer and winter design suction temperatures are within design range of either electric or pneumatic compensation devices, capacity control may be external. However, another means is normally required.

Usually modification to the compressor capacity control system is required. The compressor can be modified in 2 ways: (1) for applications requiring 50% capacity reduction; (2) for applications requiring more than one step of capacity reduction. See Fig. 10 for a typical 2-step external capacity control arrangement.

Factory Modifications — The compressor order should state that compressor is to be special for heat pump application, and is to include only enough unloader power elements to unl oad the compressor down to 50% displacement. The unloaded cylinders will be those closest to pump end of the compressor.

Field Completion — Install a

/4-in. or 3/8-in. bypass line between the control oil pressure connection and the crankcase and install a solenoid valve in this line.

The cylinders set up for unloading may be loaded or unloaded by operation of this solenoid valve. When the solenoid valve is closed, full oil pressure is available to the controlled cylinders and these will be loaded so that compressor will be operating on 100% capacity. When the solenoid valve is open, oil pressure will be bled from the controlled cylinders and they will be unloaded, so that compressor will then be operating at 50% capacity. A 2-step thermostat controlling the compressor can thus utilize 2 capacity steps by operating the compressor starter and solenoid bypass valve.

Application Requiring More Than One Step of Capacity Reduction — This can be furnished on special order for compressors having 6, 8, or 12 cylinders. Arrangement consists of

furnishing a compressor with external solenoid unloading type capacity control. The control can be furnished with or without 3-way valves (Table 18).

(%)

some systems for one of the following reasons:

1. Frequent operation at loads below minimum capacity (compressor fully unloaded).

2. To avoid low-load compressor cycling on the lowpressure switch. Excessive cycling can reduce equipment life and increase demand charges.

3. Specifications call for hot gas bypass (better humidity control, etc. ).

Page 27

The variety of systems using 5F,H compressors make it impractical to cover all aspects of hot gas bypass operation. The following guidelines will aid in determining the proper application.

The hot gas bypass valve is basically a pressure regulating valve installed to hold a constant compressor suction pressure. It should operate over as small a pressure range as possible. The normal set point of the valve should be coordinated with cylinder unloaders so that the bypass valve starts to open at a pressure where the last cylinder bank unloads, and is fully open at a slightly lower pressure. Types, ratings and published application guides for various available valves must be evaluated to determine the proper valve and inst allation practice for each application.

If a compressor system is to operate down to z ero load, the valve capacity should equal compressor capacity when fully unloaded. For systems using multiple evaporators, it may be necessary to use multiple hot gas valves.

Hot gas should be taken from a point as close as possible to compressor discharge and fed through a hot gas solenoid valve and then through a hot gas valve. The hot gas solenoid valve can be controlled by a pressure switch or temperature switch. On compressors equipped with an electrically actuated cylinder unloader, the hot gas solenoid should be wired in parallel with the solenoid that unloads the final cylinder bank so that bypassing starts immediately when all cylinders are unloaded.

HOT GAS INJECTION INTO LIQUID LINE — When amount of bypass is small and the evaporat or has a low pressure drop distribution system and existing system piping does not present problems, hot gas is frequently injected into the liquid line between the thermostatic expansion valve (TXV) and the evaporator. The ideal point for hot gas injection is into the side inlet of a side connection distributor, where inlet is downstream of distributor orifice. If too much hot gas is injected upstream of a distributor orifice, gas binding and erratic expansion valve operation will result. Injection into liquid line is recommended whenever practica l, since agitation in the evaporator and normal operation of the TXV will tend to thoroughly desuperheat injected hot gas and prevent compressor overheating.

HOT GAS INJECTION INTO COMPRESSOR SUCTION — Hot gas injection into compressor suction is sometimes necessary but must be done with caution to ensure sufficient desuperheating of hot gas and to prevent liquid slugging in t he compressor. Following guidelines should be observed:

1. Inject hot gas as close as possible to the evaporator outlet.

2. Install a TXV bulb at least 3 or 4 ft (further if possible) downstream from the hot gas injection point to ensure good gas mixing before the bulb.

3. Install a separate small TX V to inject liquid refrigerant into the suction line along with bypass gas. This valve should have capacity approximately 25% of hot gas valve capacity since hot gas must be superheated but not condensed.

4. Install a suction (knockout) drum in the suction line immediately before the compressor and downstream of the hot gas inlet and liquid injection inlet. Only larger industrial systems or systems with many remote evaporators can normally justify the extra expense of injecting hot gas into the compressor suction.

Motor Selection Data —

Motor selection data based on brake horsepower occurring at design operating condition is usually satisfactory for applications in air conditioning suction temperature range.

Required compressor starting torque is dependent on discharge pressure as well as pressure differential occurring during start-up and is the same for any compressor speed. Values shown in Table 19 indicate maximum starting torque for R-12, R-134a, R-22, R-502, and R-507/404A. In most cases, a standard torque motor can be selected because of the partially unloaded starting feature of the 5F and 5H compressors.

In selection of a motor, the required motor starting torque must exceed the compressor starting torque only when the compressor is operating at same s peed as the motor. If compressor speed is less than motor speed, as on some belt drive units, the motor starting torque requirements are reduced in proportion to the speed ratio between the compressor and motor because of mechanical advantage available to the motor.

In special applications or systems where there is a large pulldown requirement, the bhp requirement during pulldown may significantly exceed bhp at design conditions. The motor must not be overloaded during pulldown operation. If the motor is sized for pulldown, it will be only part ially loaded during design operation and will run inefficiently. Therefore, select a motor that will be optimized for system design requirements and not for pulldown requirements. Two ways for handling this are:

1. Install a crankcase pressure regulator in the system to maintain a given satu rated suction temperature, the reby controlling bhp requirement, or

2. Install a current sensing device so that the motor current draw does not exceed the maximum rated motor current.

BOOSTER COMPRESSORS FOR

REFRIGERANT 12, 22, 502, AND 507/404A

Booster Application Data —

plements the single-stage compressor application data, and adds information pertaining to booster application only. Refer to the single-stage compressor data for all other information.

Rating Basis —

ation effect and are based on:

1. Use of a liquid-suction heat interchanger. All liquidsuction interchangers should have a bypass connection on the liquid side so that adjustment can be made in event that too much superheating of suction gas causes excessive heating of compressor. This is especially true for Refrigerant 22, which has a higher compression exponent than Refrigerant 12.

All booster ratings* are given in refriger-

The following data sup-

2. The liquid refrigerant at Point A (Fig. 18) at saturation temperature corresponds to booster discharge pressure. This is often referred to as saturated intermediate temperature.

This occurs when booster discharge gas is condensed in a cascade (refrigerant-cooled) condenser, or when using an open flash-type intercooler in a direct staged system. When subcooling of liquid takes place in a closedtype intercooler, it is not possible to bring liquid temperature down to sat urated inte rmediate te mperature bec ause of temperature difference required for heat transfer through the liquid coil. In this case, the compressor rating must be decreased 3% for each 10 degrees that liquid temperature at Point A is above the saturated intermediate temperature.

3. Use of only half of the standard number of suction valve springs per cylinder. All 5F,H compressors are factory assembled with the standard number of suction valve springs; therefore, one-half of the springs per cylinder must be removed in the field for booster applications.

4. Booster ratings are based on a 1750 rpm compressor speed.

*R-507/404A ratings are similar to R-502.

“R” Factors —

In a multistage compression system, the intermediate or high-stage compressor must have sufficient capacity to handle the low-stage (booster) compressor load plus heat added to refrigerant gas by a low-stage machine during compression. Likewise, if an intermediate sta ge compressor should be used, the high-stage compressor must have sufficient capacity to handle the intermediate stage compressor load plus heat added to the refrigerant gas by an intermediate stage machine during compression.

To assist in the selection of higher stage compressors, Table 23 presents “R” factors that depict approximate required relationship between stages at various saturated temperature conditions.

To determine the required capaci ty of a higher stage compressor, multiply lower stage compressor capacity by the proper “R” factor from Table 23. Any additional loads handled at intermediate pressure must be added to this figure to arrive at the total higher stage load.

Multistage System Pointers —

A staged system is essentially a combination of 2 or more simple refrigerant cycles. In combining 2 or more simple flow cycles to for m a staged system for low temperature refrigeration, 2 basic types of combinations are common (Fig. 18).

DIRECT STAGING — Involves use of compressors, in series, compressing a single refrigerant.

CASC A D E STAGING — Usually employs 2 or more refrigerants of progressively lower boiling points. Compressed refrigerant of low stage is condensed in an exchanger (cascade condenser) that is cooled by evaporation of another lower pressured refrigerant in the next higher stage.

Safety Factors —

Use of capacity safety factors in selecting booster compressors must be a matter of judgment when making selection.

Factors that have a bearing on satisfactory compressor selections are: accuracy of load estimate, amount of safety factor included in the total load, degree of importance of meeting specified capacity at given condition, temperature level of operation and magnitude of refrigeration load. All of the factors must be recognized when considering the use of a capacity safety factor in selecting a booster compressor.

Figure 19 presents reasonable safety factors for use in selection of booster compressors. These can be employed when it is not desired to establish a factor based on selector’s judgment.

Page 30

When a capacity safety factor is used, the compressor is selected at its maximum speed to handle design load plus safety factor. Multiplying factors for non-standard speeds are shown in Fig. 20.

Whether or not added capacity offered by the safety factor is incorporated at once is a matter of judgment. If i t is, then the compressor will be operated at maximum speed at the start and any excess capacity achieved will be reflected in faster

pulldowns or lower temperatures. It is also a good practice to drive the machine at a speed that will provide slightly more rated capacity than is required by design load. Additional speed-up available will then constitut e reserve capacity in the event it is needed. Motors should be sized to run the c ompressor at maximum speed to forestall any motor changes, should this maximum compressor speed be required in the future.

Determining Intermediate Pressure —

In application of commercial compressors to staged systems, the lowest total bhp per ton and most economical equipment selection results when using approximately equal compression ratios for each stage. It is also economical to j uggle assigned compression ratios to fit available sizes of machines.

The use of Fig. 21 (page 32), will allow direct determination of proper intermediate pressure that will result in equal compression ratios per stage for a direct 2-stage system. Information in Fig. 21 is given in terms of saturated temperature instead of pressures, for easier use with compressor ratings.

Existence of a second appreciable load, at some higher suction pressure level, will often dictate the most convenient intermediate pressure.

Gas Desuperheating —

Operation of a direct staged system requires cooling of the gas between stages; otherwise, highly superheated discharge gas from low-stage machine would be taken directly into the suction of higher stage compressor and further compression would result in excessive heating of this compressor.

Liquid Cooling —

It is also necessary to employ liquid cooling between stages and increase refrigeration effect of liquid delivered to evaporator to realize rated capacity of booster compressor. Amount of refrigeration expended in cooling liquid between stages is accomplished more economically at the level of high-stage compressor suction than at the level of low-stage suction.

Three common methods of gas desuperheating and liquid cooling for direct stage systems are illustrated in Fig. 18. In open-type systems, refrigerant liquid is cooled down to the saturation temperature corresponding to intermediate pressure. In closed-type systems, good intercooler design usually results in refrigerant liquid being cooled down to 10 to 20 degrees above saturation temperature corresponding to intermediate pressure.

Oil Separators and Lubrication —

In cascade-type systems, where evaporators and suction lines are properly designed for oil return to the compressor, oil separators are usually not used.

In direct stage systems, however, oil may tend to accumulate in one of the stages and thus result in lack of lubrication in other machine. By use of oil transfer lines, equalization of oil level between crankcases can be achieved by manual operation at periodic intervals. Automatic control of proper oil return to both compressors is effected by use of a high stage discharge line oil separator, returning oil to high stage machine, and a high side float, connected to high stage machine crankcase, which continually drains excess oil from this crankcase down to the next lower stage compressor (Fig. 18).

For booster application, factory oil charge should be drained and replaced with a suitable viscosity oil for low temperature application.

Page 32

Control Pressurestat for Booster Application —

5F,H compressor cannot be used for booster application. Replace it with an appropriate low temperature dual pressurestat that can operate at values shown in Table 24. Any commercial pressure switch is acceptable; for example, an Allen-Bradley Bulletin 836, type L33 for R-12 or type 1 for R-22.

Discharge Valve Springs —

are used for booster applications where discharge pressure is below 10 psig, the standard discharge valve springs furnished with the machine should be replaced w ith an equal number of lighter weight springs, Part Number 5H41-1801.

No change in discharge valve springs is recommended for

5F compressors.

Water-Cooled Heads —

are not equipped with water-cooled heads but they are available on special order. Water cooling of heads is generally not necessary in R-12 or R-502 booster applications. For applications with R-22 involving high compression ratios, 5 or above, 5F,H booster compressors should be equipped with watercooled heads.

Motor Selection Data —

tems, the high stage compressor starts first and runs until low stage pressure has been reduced to a predetermined level before the low stage machine starts. With direct staged arrangements, the high stage machine draws gas from the evaporator through low stage machine bypass during this initial period. Size of the selected motor must be related to the maximum condition at which booster compressor can operate.

Compressor may run under heavy loads during periods of high suction pressure, especially on starting when system is warm. To handle these situations the motor must be sized larger than the actual balanced operation brake horsepower indicates, or special attention must be paid to operation of the system when starting initially. Tables 25-27 give balanced brake horsepower values at 1750 rpm.

If the system is to operate only at a fixed low temperature, it is possible to avoid oversizing of motors providing careful operation is followed when the system is first put in operation.

On applications requiring reduction from ambient conditions to some extremely low temperature, the compression system will be operated at high suction pressures for considerable periods of time. General practice is to drive the high stage compressor with a motor that will operate compressor at the highest expected evaporator temperature. This is generally the “air conditioning” rating of unit. For intermediate or low stage compressors, it is generally sufficient to size motor to take care of double the balance load indicated horsepower plus friction horsepower.

Also consider compressor starting torque requirements when selecting motor for a booster compressor. Starting torque of a motor only large enough to provide required normal operating bhp for booster applications may not be large enough to start the compressor. Recommended minimum motor sizes shown in Table 28 have been selected to assure adequate starting torque. Actual motor size selected is usually larger, depending on the maximum bhp conditions under which the compressor will run during pulldown or other abnormal operating periods.

It is good practice to select motors with allowance for 10% voltage reduction unless there is a certainty that this cannot occur.

Compressor Starting Torque —

sor starting torque is dependent on the discharge pressure as well as the pressure differential occuring during start-up. Maximum expected torque required during the starting period for 5F,H compressors, used as boosters, is shown in Table 28 at 2 saturated discharge temperatures.

Selection Procedure —

compressor requires that the load, saturated suction temperature, saturated discharge temperature, type of system and refrigerant are known.

Selection of a 5F,H booster

After the saturated intermediate temperature is determined from Fig. 21, the booster rating (Tables 25-27) can be entered and the compressor selected. Low stage load is then multip lied by the “R” factor from Table 23 to obtain high stage compressor load. With this information, the Compressor Ratings tables on pages 7-15, and page 17 can be entered and the high-stage compressor selected.

Find:

Compressor size and motor size.

Solution:

1. Figure 21 indicates an optimum saturated intermediate temperature of –2 F. Allow a 1 degree or 2 degree drop from the booster compressor to intercooler and from the intercooler to the high stage compressor.

Booster Saturated Suction Temperature = –60 F Booster Saturated Discharge Temperature = 0° F

2. At –60 F suction and 0° F discharge, the 5H60 booster compressor has a capacity of 6.8 tons with 12.1 bhp input at 1750 rpm.

The safety factor at 1750 rpm:

6.8

(

This is satisfactory from Fig. 19 and a 5H60 compressor is selected.

3. Indicated hp (ihp) = bhp – Friction hp (fhp) Where bhp is given in Table 26 and fhp is given in

T able 28 . Indicated hp (ihp) = 12.1 – 3.07 = 9.03 Recommended minimum hp = (2 x ihp) + fhp

= (2 x 9.03) + 3.07 = 21.13 Tentatively select a 25-hp motor. Assume that low stage

will never start against a saturated discharge higher than 30 F. At 30 F discharge, Table 28 indicates a starting torque of 54 lb-ft. Therefore, a normal starting torque 25-hp motor is selected.

4. With –60 F suction and 0° F discharge, Table 23 indicates an “R” value of 1.303. Therefore, the high stage load is:

5. Allowing a 1 degree drop from the intercooler, the high stage saturation suction temperature is –3 F.

Allowing a 2 degree drop between the compressor and condenser, the high stage saturated discharge temperature = 80 + 2 = 82 F.

6. Referring to the 5F,H Compressor Ratings table, 5F60 at 1450 rpm (using multiplier in compressor capacity notes) has a capacity of 9.21 tons at –3 F suction and 82 F discharge (through interpolation). The 5F60 is selected and requires 13.0 bhp at 1450 rpm.

7. Assume that maximum load during pulldown occurs at 50 F suction and 90 F discharge. For this condition, the rating tables (using the multiplier in Step 6) indicate

15.8 bhp, thus a 20-hp motor is selected.

CONDENSERS

Condenser Physical Data —

fer to 5F,H Product Data for information on the current P701 water-cooled condensers used with the 5F,H watercooled condensing units.

Condenser Selection Considerations —

installations the condenser is selected within recommended conditions specified in ARI Standards. Main considerations are:

1. The water velocity is within a range of 1 to 12 ft per second (to minimize corrosion and erosion).

2. It is good practice to select condensers on a leaving temperature difference between 6 and 12 degrees. In general, higher temperature differences are used only where condensing water temperature is quite low or where special conditions make it economical to do so. A high temperature difference not only makes effect of fouling more pronounced but since the condenser volume is likely to be small, the effect on noncondensable gases will be greater.

Table 30 lists maximum water velocities from Carrier System Design Manual. Limits are above ARI recommended values but are generally accepted where ARI conformance is not specified. See Part 5 of the Carrier System Design Manual for further details.

Table 31 lists condenser water quantities (gpm) for water velocities from 3 to 12 fps. For higher velocities, use formulas below Tabl e 31.

Condenser Duty —

is greatest at high saturated suction tempe ratures. Because of this, the compressor normally requires the largest condenser at these conditions or for air conditioning duty.

On refrigeration or low temperature applications, the same compressor displacement results in a lower refrigeration capacity and, consequently, less heat rejection. Thus, condenser size is smaller than would normally be required with the same compressor on air conditioning duty.

Condenser size is also affected by refrigerant used, since compressor capacities (and thus heat rejection) differ with Refrigerants 12, 22, and 502.

Pulldown —

periods, especially low temperature or multistage systems, should be oversized beyond the capacity required at the final balanced load condition. The condenser must adequately

capacity is substantially greater than at final condition.

If pulldown load is sizable, as in most water or brine cooling applications, check the condenser performance when it is handling total heat rejection at maximum rated suction temperature (50 F for most compressors). Condenser size and water

On most

quantity must be adequate to handle this start-up load without resulting in excessive head pressure or excessive w ater pressure drop. As a rough guide, the selected condenser should have a maximum total heat rejection rating that is equal to or greater than the compressor heat rejection at pulldown conditions.

If this pulldown occurs infrequently, it may be possible to select a condenser for design conditions a nd on each start-up limit compressor capacity by manually throttling suction gas flow. This can be done by pa rtially closing suction valve but this will extend time required to reach design conditions.

If the pulldown is of short duration, such as on a direct expansion coil, suction temperature will drop very rapidly and more than likely design conditions will be reached before t he compressor would cut out on high pressure. No oversizing of the condenser would be required.

Whenever possible, the selected condenser should never be of a larger size than the largest condenser that will match the compressor used and still be a standard combination. This should be considered especially when the condensers are to be used with 5F ,H series open reciprocating compressors.

Fouling and Fouling Factors —

The capacity of a given compressor

denser tubes is result of a build-up of scale within tubes because of impurities in water. As a result, heat transfer is adversely affected. Fouling factors are a means of identifying degree of fouling.

Condensers should not be selected for less than 0.0005 fouling factor, even when high quality water is available. For lower quality water, use larger fouling factors from the condenser ratings, but temper factor according to operating conditions.

The following affect magnitude of fouling factor selected:

• Percentage of yearly operating time.

• Frequency of tube cleaning.

• Condensing temperature.

• Type of water treatment.

For instance, reduce fouling factor when the operating time is less than 4000 hours per year, when frequent cleaning of tubes takes place, or when low condensing temperatures exist.

Water Circuiting Arrangements —

The water circuiting arrangement selected for 5F and 09RH condensers depends on available condenser water pressure, temperature, quantity and source. Refer to Table 32.

Refer to the Carrier System Design Manual for specific information and recommendations for refrigerant and water piping.

Economics —

Selection of a condenser requires balancing

of certain economic variables, including:

1. First cost of compressor-condenser combination.

2. Operating costs.

3. Ratio between power costs and water costs. Where first cost is the most important consideration, the

best combination of compressor and condensers has the lowest total equipment cost.

If owning and operating costs are important, combination

must be selected on basis of both considerations.

A condenser selection that permits operation of the system

at a low condensing temperature, results in the lowest compressor motor brake horsepower and consequently, lowest operating cost. A condenser selection that is heavily loade d requires the compressor to operate at a higher condensing temperature and results in higher compressor motor brake horsepower and operating cost.

For a given compressor-condenser combination, selection

of a condensing temperature may depend on a ratio between power costs and water costs, on quantity of water available, on condensing temperature required to achieve compressor capacity, or a requirement to remain within allowable loading on a given motor size.

Condenser Performance with Ethylene Glycol —

The 85 F value is return water temperature from closed cir-

Entering condenser rating data at loading factor of 7.9, 300 gpm are required to maintain design condensing temperature. Next, determine the rise by:

If a more precise rise is desired, go back and assume a slightly different condensing temperature, recalculate the loading factor and rise and repeat the procedure until a final balance is found.

For this example, condenser water pressure drop is approximately 9.4 ft for the design 300 gpm flow rate. Using Fig. 22, flow rate correction can be determined for any glycol concentration versus water in shell and tube condensers.

Continuing with example, assume specifications required protection against freeze-up at an ambient of 0° F. (A glycol concentration that provides protection between 10 and 15 degrees below expected minimum ambient has been the design criteria for many years.)

In a condenser system, the use of proper ethylene glycol brine concentration is important because of the phenomenon that commonly published freeze points are not freeze points but are the point of crystallization where the first crystals begin to form. Actual freezing into a solid occurs at much lower temperatures. For example, freeze point of 20% ethylene glycol is given as +16 F but does not become a solid until it reaches –50 F; 35% ethylene glycol with a freeze point of –6 F does not become solid until it reaches –120 F. Consequently, 20% glycol solution will take care of most domestic applications and 35% brine should satisfy the rest. The lowest concentration of brine will be the most efficient and result in considerable energy conservation.

Entering Fig. 22 at 0° F crystallization point, necessary concentration of glycol is either 32.5% by weight or 30% by volume. Next, determine glycol flow rate:

Glycol Flow Rate =

Therefore, at 32.5% by weight ethylene glycol specified and used to satisfy design conditions, a flow rate of 513 gpm of brine solution would be required and this value used to select a closed circuit cooler. Closed circuit cooler selection can be made from the manufacturer’s literature or by contacting the local representative.

Next determine the glycol pressure drop. Equiv W ater Flow = Glycol Flow x Press. Drop Factor

Pressure drop factor can be determined by entering Fig. 22 at the proper concentration of glycol solution (30% by volume), going to the pressure drop factor line and reading right to the pressure drop factor. For this example the factor is 1.1.

Equiv W ater Flow = 513 x 1.1

= 564 Gpm

Entering condenser water pressure drop curve in product literature at 564 gpm, the brine pressure drop can be determined. Note there will be an increase in flow rate and pressure drop with ethylene glycol as compared to a straight water cooling system.

In conclusion, add a glycol solution to a condenser system only when conditions warrant. Do not add more than is required. When glycol is used, proper control of inhibitor concentration is necessary to maintain design properties of solution and prevent corrosion.
