APPLICATION AND SIZING

In the application and sizing of room air conditioners for cooling, it is most important to give full consideration to all factors which may contribute to the heat loss or gain of the space to be conditioned. It is therefore necessary to make a survey of the space to be conditioned and calculate the load requirements before a selection of the size of the equipment needed can be made.

The load requirement may be determined very easily by simply using the standard “AHAM” Load Calculating Form, on Page 6. This form is very easy to use and is self explanatory throughout. It is necessary only to insert the proper measurements on the lines provided and multiply by the given factors, then add the result for the total load requirements.

Cooling load requirements are generally based on the cooling load for comfortable air conditioning which does not require specific conditions of inside temperature and humidity. The load calculation form is based on outside design temperature of 95° FDB and 75° FWB. It can be used for areas in the Continental United States having other outside design temperatures by applying a correction factor for the particular locality as determined from the map shown on Page 6.

When sizing a TwinTemp unit for cooling and heating, we must remember that the heating capacity of any given unit varies directly with the outdoor ambient temperature. Also, we must keep in mind the average low temperatures which might be experienced in the locality where the unit is to be installed. Therefore, when sizing a TwinTemp unit, both cooling and heating requirements must be calculated. Do not oversize, or undersize, one phase of the unit’s capacity at the expense of the other. In those cases where the unit will provide satisfactory cooling at all times but will be inadequate for those few times that the outdoor temperature is below the maximum low for the unit, additional auxiliary heating facilities must be provided to insure that adequate heat is available at all times.

INSTRUCTIONS FOR USING COOLING LOAD ESTIMATE

FORM FOR ROOM AIR CONDITIONERS

(AHAM PUB. NO. RAC-1)

A.This cooling load estimate form is suitable for estimating the cooling load for comfort air conditioning installations which do not require specific conditions of inside temperature and humidity.

B.The form is based on an outside design temperature of 95°F dry bulb and 75°F wet bulb. It can be used for areas in the continental United States having other outside design temperatures by applying a correction factor for the particular locality as determined from the map.

C.The form includes“day” factors for calculating cooling loads in rooms where daytime comfort is desired (such as living rooms, offices, etc.)

D.The numbers of the following paragraphs refer to the corresponding numbered item on the form:

1.Multiply the square feet of window area for each exposure by the applicable factor. The window area is the area of the wall opening in which the window is installed. For windows shaded by inside shades or venetian blinds, use the factor for “Inside Shades.” For windows shaded by outside awnings or by both outside awnings and inside shades (or venetian blinds), use the factor for “Outside Awnings.” “Single Glass” includes all types of single thickness windows, and “Double Glass” includes sealed airspace types, storm windows, and glass block. Only one number should be entered in the right hand column for Item 1, and this number should represent only the exposure with the largest load.

2.Multiply the total square feet of all windows in the room by the applicable factor.

3a. Multiply the total length (linear feet) of all walls exposed to the outside by the applicable factor. Doors should be considered as being part of the wall. Outside walls facing due north should be calculated separately from outside walls facing other directions. Walls which are permanently shaded by adjacent structures should be considered “North Exposure.” Do not consider trees and shrubbery as providing permanent shading. An uninsulated frame wall or a masonry wall 8 inches or less in thickness is considered “Light Construction.” An insulated wall or masonry wall over 8 inches in thickness is considered“Heavy Construction.”

3b. Multiply the total length (linear feet) of all inside walls between the space to be conditioned and any unconditioned spaces by the given factor. Do not include inside walls which separate other air conditioned rooms.

4.Multiply the total square feet of roof or ceiling area by the factor given for the type of construction most nearly describing the particular application (use one line only.)

5.Multiply the total square feet of floor area by the factor given. Disregard this item if the floor is directly on the ground or over a basement.

6.Multiply the number of people who normally occupy the space to be air conditioned by the factor given. Use a minimum of 2 people.

7.Determine the total number of watts for light and electrical equipment, except the air conditioner itself, that will be in use when the room air conditioning is operating. Multiply the total wattage by the factor given.

8.Multiply the total width (linear feet) of any doors or arches which are continually open to an unconditioned space by the applicable factor.

NOTE: Where the width of the doors or arches is more than 5 feet, the actual load may exceed the calculated value. In such cases, both adjoining rooms should be considered as a single large room, and the room air conditioner unit or units should be selected according to a calculation made on this new basis.

9.Total the loads estimated for the foregoing 8 items.

10.Multiply the subtotal obtained in item 9 by the proper correction factor, selected from the map, for the particular locality. The result is the total estimated design cooling load in BTU per hour.

E.For best results, a room air conditioner unit or units having a cooling capacity rating (determined in accordance with the NEMA Standards Publication for Room Air Conditioners, CN 1-1960)as close as possible to the estimated load should be selected. In general, a greatly oversized unit which would operate intermittently will be much less satisfactory than one which is slightly undersized and which would operate more nearly continuously.

F.Intermittent loads such as kitchen and laundry equipment are not included in this form.

COMPONENTS OPERATION & TESTING

WARNING

DISCONNECT ELECTRICAL POWER TO UNIT BEFORE SERVICING OR TESTING

COMPRESSORS

Compressors are single phase, 15 or 230/208 volt, depending on the model unit. All compressor motors are permanent split capacitor type using only a running capacitor across the start and run terminal.

All compressors are internally spring mounted and externally mounted on rubber isolators.

COMPRESSOR WINDING TEST (See Figure 1)

Remove compressor terminal box cover and disconnect wires from terminals. Using an ohmmeter, check continuity across the following:

1.Terminal “C” and “S” - no continuity - open winding - replace compressor.

2.Terminal “C” and “R” - no continuity - open winding - replace compressor.

3.Terminal “R” and “S” - no continuity - open winding - replace compressor.

Figure 1: Compressor Winding Test

GROUND TEST

Use an ohmmeter set on its highest scale. Touch one lead to the compressor body (clean point of contact as a good connection is a must) and the other probe in turn to each compressor terminal (see Figure 2.) If a reading is obtained, the compressor is grounded and must be replaced.

Figure 2: Typical Ground Test

CHECKING COMPRESSOR EFFICIENCY

The reason for compressor inefficiency is normally due to broken or damaged suction and/or discharge valves, reducing the ability of the compressor to pump refrigerant gas.

This condition can be checked as follows:

1.Install a piercing valve on the suction and discharge or liquid process tube.

2.Attach gauges to the high and low sides of the system.

3.Start the system and run a “cooling or heating performance test.”

If test shows:

A.Below normal high side pressure.

B.Above normal low side pressure.

C.Low temperature difference across coil.

The compressor valves are faulty - replace the compressor.

THERMAL OVERLOAD (External)

Some compressors are equipped with an external overload which is located in the compressor terminal box adjacent to the compressor body (see Figure 3.)

Page 8

The overload is wired in series with the common motor terminal.The overload senses both major amperage and compressor temperature. High motor temperature or amperage heats the disc causing it to open and break the circuit to the common motor terminal.

Figure 3: External Overload

Heat generated within the compressor shell is usually due to:

1.High amperage.

2.Low refrigerant charge.

3.Frequent recycling.

4.Dirty condenser.

THERMAL OVERLOAD - TEST

(Compressor - External Type)

1.Remove overload.

2.Allow time for overload to reset before attempting to test.

3.Apply ohmmeter probes to terminals on overload wires.There should be continuity through the overload.

TERMINAL OVERLOAD (Internal)

Some model compressors are equipped with an internal overload. The overload is embedded in the motor windings to sense the winding temperature and/or current draw. The overload is connected in series with the common motor terminal.

Should the internal temperature and/or current draw become excessive, the contacts in the overload will open, turning off the compressor. The overload will automatically reset, but may require several hours before the heat is dissipated.

CHECKING THE INTERNAL OVERLOAD

(see Figure 4.)

Figure 4

1.With no power to unit, remove the leads from the compressor terminals.

2.Using an ohmmeter, test continuity between terminals C-SandC-R.If not continuous, the compressor overload is open and the compressor must be replaced.

FAN MOTOR

A single phase permanent split capacitor motor is used to drive the evaporator blower and condenser fan. A self-resettingoverload is located inside the motor to protect against high temperature and high amperage conditions.

FAN MOTOR - TEST

1.Determine that capacitor is serviceable.

2.Disconnect fan motor wires from fan speed switch or system switch.

3.Apply“live” test cord probes on black wire and common terminal of capacitor. Motor should run at high speed.

4.Apply “live” test cord probes on red wire and common terminal of capacitor. Motor should run at low speed.

Page 9

Figure 5: Fan Motor

5.Apply “live” test cord probes on each of the remaining wires from the speed switch or system switch to test intermediate speeds.

CAPACITOR, RUN

A run capacitor is wired across the auxiliary and main winding of a single phase permanent split capacitor motor such as the compressor and fan motor. A single capacitor can be used for each motor or a dual rated capacitor can be used for both.

The capacitor’s primary function is to reduce the line current while greatly improving the torque characteristics of a motor. The capacitor also reduces the line current to the motor by improving the power factor of the load. The line side of the capacitor is marked with a red dot and is wired to the line side of the circuit (see Figure 6.)

Figure 6: Run Capacitor Hook-Up

CAPACITOR - TEST

1.Remove capacitor from unit.

2.Check for visual damage such as bulges, cracks, or leaks.

3.For dual rated, apply an ohmmeter lead to common (C) terminal and the other probe to the compressor (HERM) terminal. A satisfactory capacitor will cause a deflection on the pointer, then gradually move back to infinity.

4.Reverse the leads of the probe and momentarily touch the capacitor terminals.The deflection of the pointer should be two times that of the first check if the capacitor is good.

5.Repeat steps 3 and 4 to check fan motor capacitor.

NOTE: A shorted capacitor will indicate a low resistance and the pointer will move to the “0” end of the scale and remain there as long as the probes are connected.

An open capacitor will show no movement of the pointer when placed across the terminals of the capacitor.

SYSTEM CONTROL SWITCH

A five position control switch is used to regulate the operation of the fan motor and compressor.The compressor can be operated with the fan operating at low, medium or high speed.The fan motor can also be operated independently on medium speed. See switch section as indicated on decorative control panel (see Figure 7.)

SYSTEM CONTROL SWITCH - TEST

Disconnect leads from control switch (see Figure 8.) There must be continuity as follows:

1.“Off” Position - no continuity between terminals.

2.“Lo Cool” Position - between ter minals “L1” and “C”, “LO” and “MS”.

3.“Med Cool” Position - between ter minals “L1” and “C”, “M” and “MS”.

4.“Hi Cool” Position - between ter minals “L1” and “C”, “H” and “MS”.

5.“Fan Only” Position - between ter minals “L1” and “2”.

Page 10

Figure 7: System Control Panel

Figure 8: System Control Switch

to supply a small amount of heat to the bulb area to prevent long “off cycles” in the “Cool-FanAuto” (MoneySaver) position (see Figure 10.) A current feedback through the fan motor windings during “off cycle” completes the circuit to the resistor.

RANGE:

Cooling Model Thermostat

 

(Part No. 618-225-00)

60°F (± 2°) to 92°F (± 4°),

TEST:

Remove wires from thermostat. Turn the thermostat to its coldest position. Check to see if there is continuity between the two terminals. Turn the thermostat to its warmest position. Check continuity to see if thermostat contacts open. NOTE: Temperature must be within range listed to check thermostat. Refer to the troubleshooting section in this manual for additional information on thermostat testing.

Figure 9: Thermostat

THERMOSTAT (Figure 9)

A cross ambient thermostat is used on all standard chassis units. In addition to cycling the unit in a heating or cooling operation, the thermostat will terminate the cooling cycle in the event ice forms on the evaporator coil, in this case the thermostat functions as a de-icecontrol. A resistor (anticipator) is positioned within a plastic block

THERMOSTAT ADJUSTMENT

No attempt should be made to adjust thermostat. Due to the sensitivity of the internal mechanism and the sophisticated equipment required to check the calibration, it is suggested that the thermostat be replaced rather than calibrated.

Page 11

RESISTOR

(Heat Anticipator)

Failure of the resistor will cause prolonged“off” and “on” cycles of the unit. When replacing a resistor, be sure and use the exact replacement. Resistor ratings are as follows:

115 Volt - 5,000 ohms 3 watt

230 Volt - 20,000 ohms 3 watt

Figure 10 RESISTOR

MONEYSAVER® SWITCH

(Rocker Switch) - (See Figure 11)

This rocker switch can be depressed to either YES orNO. In theYES position you will get the most economical operation. Both the fan and compressor will cycle on and off together, maintaining the selected temperature at a more constant level and reducing the humidity more efficiently.This control will only operate when the unit is in a cooling mode. In theNO position, the fan will run constantly as long as the unit is in the cooling mode.

TEST:

Disconnect leads from switch. Depress switch to function being tested.

1.When YES is depressed, there should be continuity between terminals “1” and “2”.

2.When NO is depressed, there should be continuity between terminals “2” and “3”.

HERMETIC COMPONENT REPLACEMENT

The following procedure applies when replacing components in the sealed refrigeration circuit or repairing refrigerant leaks. (Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.)

7.Leak test complete system with electric halogen leak detector, correcting any leaks found.

8.Reduce the system to zero gauge pressure.

9.Connect vacuum pump to high side and low side of system with deep vacuum hoses, or copper tubing. (Do not use regular hoses.)

10.Evacuate system to maximum absolute holding pressure of 200 microns or less. NOTE: This process can be speeded up by use of heat lamps, or by breaking the vacuum with refrigerant or dry nitrogen at 5,000 microns. Pressure system to 5 PSIG and leave in system a minimum of 10 minutes. Recover refrigerant, and proceed with evacuation of a pressure of 200 microns or a minimum of 10 %.

11.Break vacuum by charging system from the high side with the correct amount of refrigerant specified.This will prevent boiling the oil out of the crankcase.

NOTE: If the entire charge will not enter the high side, allow the remainder to enter the low side in small increments while operating the unit.

12.Restart unit several times after allowing pressures to stabilize. Pinch off process tubes, cut and solder the ends. Remove pinch off tool, and leak check the process tube ends.

1.Recover the refrigerant from the system at the pro-

cess tube located on the high side of the system by SPECIAL PROCEDURE IN THE CASE OF

installing a line tap on the process tube.Apply gauge from process tube to EPA approved gauges from process tube to EPA approved recovery system. Recover CFCs in system to at least 5%.

2.Cut the process tube below pinch off on the suction side of the compressor.

3.Connect the line from the nitrogen tank to the suction process tube.

4.Drift dry nitrogen through the system and unsolder the more distant connection first. (Filter drier, high side process tube, etc.)

5.Replace inoperative component, and always install a new filter drier. Drift dry nitrogen through the system when making these connections.

6.Pressurize system to 30 PSIG with proper refrigerant and boost refrigerant pressure to 150 PSIG with dry nitrogen.

MOTOR COMPRESSOR BURNOUT

1.Recover all refrigerant and oil from the system.

2.Remove compressor, capillary tube and filter drier from the system.

3.Flush evaporator condenser and all connecting tubing with dry nitrogen or equivalent, to remove all contamination from system. Inspect suction and discharge line for carbon deposits. Remove and clean if necessary.

4.Reassemble the system, including new drier strainer and capillary tube.

5.Proceed with processing as outlined under hermetic component replacement.

ROTARY COMPRESSOR SPECIAL

TROUBLESHOOTING AND SERVICE

Basically, troubleshooting and servicing rotary compressors is the same as on the reciprocating compressor with only a few exceptions.

1.Because of the spinning motion of the rotary, the mounts are critical. If vibration is present, check the mounts carefully.

2.The electrical terminals on the rotary are in a different order than the reciprocating compressors. The terminal markings are on the cover gasket. Use your wiring diagram to insure correct connections.

REFRIGERANT CHARGE

1.The refrigerant charge is extremely critical. Measure charge carefully - as exact as possible to the nameplate charge.

2.The correct method for charging the rotary is to introduce liquid refrigerant into the high side of the system with the unit off. Then start compressor and enter the balance of the charge, gas only, into the low side.

The introduction of liquid into the low side, without the use of a capillary tube, will cause damage to the discharge valve of the rotary compressor.

NOTE: All inoperative compressors returned to Friedrich must have all lines properly plugged with the plugs from the replacement compressor.
