CAPACITY CONTROL

A. Standard settings:

These chillers are equipped with stepless capacity control system as standard for very accurate response to load requirements and best part load efficiency. Each compressor is equipped with a slider controller that enables to modulate capacity between 25% to 100%, thus giving a broad range to control total chiller capacity between 10% to 100% on an average. This system has following advantages:

1. Infinite capacity modulation allows the compressor capacity to exactly match the cooling load.

2. Reduce compressor cycling that leads to better operational reliability.

3. Reduce operating cost.

B. Optional settings:

The COOLINE packaged chillers incorporate stepped load shedding as required by some energy management systems. Modulation of capacity in response to system load requirements is affected by a microprocessor controller which monitors the leaving water temperature.

Capacity control is achieved by cycling compressor ON/OFF and slider capacity pre-set control valve. The use of slider control valve provides excellent part load capacities.

On multiple compressor units, capacity is controlled by a combination of slider capacity control valve and compressor staging. For such optional stepped load shading, please see the following table.

SELECTION PROCEDURE (English units)

DESIGN REQUIREMENTS

The following design requirements must be known to select a package chiller.

1. Required cooling capacity in tons

2. Leaving chilled water temperature in 0F (LCWT)

3. Chilled water flow rate in GPM

4. Chilled water cooling range in 0F (water in temp. _ water out temp.)

5. Design ambient temperature

6. Minimum ambient temperature

7. Altitude

8. Electrical power supply

SAMPLE SELECTION

Select an Air Cooled Packaged chiller for the following conditions: Required system capacity is 110 tons at 540F entering chilled water and 440F leaving water. Design ambient temperature is 950F. Altitude is 2000 feet above sea level. Water cooler fouling factor is 0.00010. Power supply: 380/415V-3Ph-50Hz.

STEP-1: UNIT SELECTION Entering the capacity performance data at given LCWT and ambient temperature.

ASQ115B chiller unit at sea level will produce 115.3 tons and 120.3 kW compressor

power input at 44

F leaving chilled water temperature with 100F water temperature

difference and 950F ambient temperature.

For the conditions required, the unit actual cooling capacity when corrected for altitude (0.99) and fouling factor (1.0). Capacity = 115.3x0.99x1.0 = 114.1 Tons, which then exceeds the requirements. So the selection is correct.

STEP-2: CHILLED WATER FLOW (GPM):

, the main power wire size for ASQ115B is to be sized for a minimum circuit

ampacity (MCA) of 292 Amps and maximum over current protection (MOCP) of 411 Amps.

STEP-4: CHILLED WATER PUMP SELECTION For chilled water pump selection, add all pressure drop in the closed chilled water loop piping to the pressure drop

calculated in step 2.

STEP-5: LCWT CORRECTION Refer to table-3: Add correction factor to design leaving chilled water temperature (LCWT) when chilled water tempera-

ture range is above 10

F and subtract correction from design leaving chilled water temperature (LCWT) when water

temperature range is below 100F. EXAMPLE:

If LCWT rise is 12.5

F, enter correction curve at 12.50F and read the correction factor of 0.2. The corrected LCWT is

44+0.2 = 44.20F.

NOTE: 1.When the chilled water temperature rise is less than 50F, the high water flow rate will result to excessive

pressure drop. In such cases, contact factory for special selection of a cooler with wider baffle spacing.

2.Please refer to water pressure drop curves.

MICROPROCESSOR CONTROLLER

Sequence of Operation

The following describes the sequence of operation for a two screw compressor chiller unit. Operation is similar for a one or four compressor unit. For initial start-up, the following conditions must be met:

All power supplied to the unit shall be energized for 12 hours.

Control power switch on for at least 5 minutes.

All safety conditions satisfied.

Press ESC on the microcomputer keypad.

Chilled water pump running and chilled water flow switch contact closed.

Customer interlock contact closed, if any.

STAGE - ON SEQUENCE

Staging ON & OFF sequence, shall be accomplished by the Leaving water temperature control selection.

Stage #1:

If the Leaving Water Temperature is greater than the Stage 1- ON water temperature set point value, the Compressor #1 liquid line solenoid & slider control valves shall be switched ON. Now the compressor is in the minimum or unloaded capacity. The compressor capacity is varied to achieve the full/part load capacity as per the load demand.

As discharge pressure of Compressor #1 rises, the corresponding fans are energize accordingly to the fan stage-ON set point. If the discharge pressure falls below the fan stage-OFF set point value, the corresponding fans will turn off.

Stage #2:

If the Leaving Water Temperature is greater than the Stage 2- ON water temperature set point value, the Compressor #2 liquid line solenoid & slider control valves shall be switched ON. Now the compressor is in the minimum or unloaded capacity. The compressor capacity is varied to achieve the full/part load capacity as per the load demand.

As discharge pressure of Compressor #2 rises, the corresponding fans are energize accordingly to the fan stage-ON set point. If the discharge pressure falls below the fan stage-OFF set point value, the corresponding fans will turn off.

STAGE - OFF SEQUENCE

During the staging OFF, the first-in last-out sequence is adopted, if equalization of compressor timing is not selected. Else the more used is switched off.

As the applied load decreases and when the leaving water temperature falls below the stage 2 -OFF water temperature set point value, stage 2 is turned off.

If the leaving water temperature falls below the stage 1-OFF water temperature set point value, the stage 1 is turned off.

APPLICATION GUIDELINES

INTRODUCTION

These guidelines should be considered when designing systems and their installation utilizing COOLINE ASQ series liquid chillers. Stable operation, performance and reliability of units is often dependent upon proper compliance with these recommendations. When any application varies from these guidelines, it should be referred with Cooline Air Conditioners for specific recommendations.

UNIT SELECTION/SIZING

Unit selection procedure and capacities are provided in this catalog for proper selection. The COOLINE electronic selection program may also be utilized for this purpose.

Over sizing chillers beyond a maximum limit of 5 – 10 % in order to assure adequate capacity or considering future expansions is not recommended. Over sizing adversely affects the operating efficiency due to erratic system operation and excessive compressor cycling which also results in reduced compressor life. It should be noted that, units operate more efficiently when fully loaded rather than larger equipment operating at partial capacities. In addition, an oversized unit is usually more costly to purchase, install and operate.

When over sizing is desired due to anticipation of future plant expansion, consider using multiple units. For example, install a single chiller for the present load requirement and install a second chiller for the foreseen additional load demand due to expansion. Further, it is also recommended that installing two chillers instead of a single chiller be considered in applications where partial load operation at low capacities is necessary.

Operation of two chillers at higher loading is preferred to operating a single chiller at or near its minimum possible capacity.

FOULING FACTOR AND WATER REQUIREMENT

The tabulated performance data provided in this catalog are based on a fouling factor of 0.00010 hr-ft2-0F/Btu (0.000018 m2-0C/W). As fouling factor is increased, unit capacity decreases and power input increases. For unit selection at other fouling factors, apply appropriate correction factor from the table provided in this catalog.

These chillers are suitable for operation with well maintained water systems. Using unclean and untreated water may result in scale and deposit formation causing reduced cooler efficiency or heat transfer and corrosion or pitting leading to possible equipment damage. The more scale forming material and suspended solids in the system water, the greater the chances of scale and deposit formation and fouling. These include calcium, magnesium, biological growth (algae, fungi and bacteria), dirt, silt, clays, organic contaminants (oils), silica, etc. which should be kept to the minimum to retard scale and deposit formation. In order to prevent corrosion and pitting, the pH value of the water flowing through the cooler must be kept between 7 and 8.5. COOLINE recommends that a water treatment specialist is consulted to provide and maintain water treatment, this is particularly critical with glycol systems.

EFFECT OF ALTITUDE ON UNIT CAPACITY

The tabulated performance data provided in this catalog are for use at or near sea level altitude application. substantially above sea level, the decreased air density will reduce condenser capacity and therefore unit capacity. For unit selection at these higher altitudes, apply appropriate correction factor from the table provided in this catalog.

At altitudes

HIGH AMBIENT CONSIDERATION

These chillers are designed for year round operation over a range of ambient temperatures. As a standard, these chillers can start and operate satisfactorily up to 1250F (520C) ambient temperature at rated nominal voltage.

WATER FLOW RATES AND COOLER PRESSURE DROP

The maximum and minimum water flow rates for all unit models and the pressure drop chart are provided in this catalog. The design water flow rate must be within this range. Design flow rates below the minimum limits will result in laminar flow causing freeze-up problems, stratification and poor control and flow rates beyond the maximum limits cause excessive pressure drop and severe tube erosion.

During unit operation, water flow rate must not vary more than ± 5% from the design flow rate. The water flow switch should be calibrated accordingly. The piping and pumping layout should be right for the application and must assure proper water return and circulation. When using glycol solution, flow rate and pressure drop are higher than with water, therefore care must be taken not to exceed the limits. In such applications, consult Cooline Air Conditioners for specific recommendations.

COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGE

Unit can start and pull down from 950F (350C) entering fluid temperature. The design leaving chilled fluid temperature (LCWT) range as mentioned earlier in the tabulated performance data is 40 to 500F. The design entering chilled fluid temperature range is 50 to 600F. The design cooler temperature drop (∆T) range is 5 to 150F.

The tabulated performance data provided in this catalog is based on a chilled water temperature drop of 100F. Units may be operated at any desired temperature drop within the range of 5 to 150F as long as the temperature and flow limits are not violated and appropriate correction factors are applied on the capacity and power input. The COOLINE electronic selection program can be very handy in selecting equipment at different temperature drops.

It should be noted that temperature drop outside the aforesaid range is not permitted as it is beyond the optimum range of control and could adversely affect the functioning of microprocessor controller and may also prove to be detrimental for the equipment.

FLOW RATES AND/OR WATER TEMPERATURES OUT OF RANGE

Certain applications (particularly process cooling jobs) call for flow rates and/or water temperatures that are outside the above mentioned limits/range. Our chillers can be utilized for these applications by selecting the chiller based on the specific process load and making a suitable piping and mixing arrangement in order to bring the flow rates and/or water temperatures relevant to the chiller within acceptable limits.

Example 1:

An application requires 240 GPM of water at 450F and the return water temperature is 650F. A standard chiller can be used for this application as shown in the following basic schematic layout (single mixing arrangement).

COOLER FREEZE PROTECTION

If the unit is located in an area where ambient temperatures fall below 320F (00C), cooler protection in the form of Ethylene Glycol Solution is required to protect the cooler and fluid piping from low ambient freeze-up. This glycol solution must be

added to the water system loop to bring down the freezing point of water to a difference of 15

F (8.30C) below minimum

operating ambient temperature.

Using this glycol solution causes a variation in unit performance, flow rate and pressure drop, therefore appropriate correction factors from the aforementioned table in this catalog should be applied.

MULTIPLE CHILLER ARRANGEMENT OR PLANT CONFIGURATION

A multiple chiller system has two or more chillers connected by parallel or series piping to a common distribution system. Multiple chiller arrangements offer the advantage of operational flexibility, standby capacity and less disruptive maintenance. Also, they offer some standby capacity if repair work must be done on a chiller from a set of duty chillers. Starting in-rush current is reduced, as well as power costs at partial-load conditions.

A multiple chiller arrangement should be provided if the system load is greater than a single chiller capacity, standby

capability is desired, large temperature drop (greater than 15

F) is desired or application calls for splitting the total

capacity for better part load operation.

In designing a multiple chiller plant, units of same size should be preferred over different sizes to facilitate balanced water flow. It is mandatory that cooler flow rates must be balanced to ensure proper flow to each chiller based on its respective capacity. As mentioned above, two basic multiple chiller systems are used: parallel and series chilled water flow.

In the parallel arrangement, liquid to be chilled is divided among the liquid chillers; the multiple chilled streams are combined again in a common line after chilling. Water temperatures (EWT or LWT) can be used to cycle units On and Off based on the cooling demand. Parallel arrangements permit adding chillers in the future for plant expansion with the appropriate considerations beforehand.

In the series arrangement, the chilled liquid pressure drop may be higher unless coolers with fewer liquid-side passes or baffles are used. No over chilling by either unit is required, and compressor power consumption is lower than it is for the parallel arrangement at partial loads. It is also possible to achieve higher overall entering to leaving temperature drops, which may in turn provide the opportunity for lower chilled water design temperature, lower design flow and resulting installation and operational cost savings. Series chiller arrangements can be controlled in several ways based on the water temperatures depending on cooling demand.

A valved piping bypass is suggested around each chiller to facilitate future servicing as it gives the personnel an option for service without a complete shutdown.

COOLINE recommends the parallel arrangement for design temperature drops (∆T) up to 15

ment beyond that i.e., 16 to 20

can be found in the ASHRAE handbooks and other design literature which should be referred by the designer in preparing his detailed designs.

PIPING ARRANGEMENTS AND PLANT LAYOUT

Our chillers are suitable for incorporating in ‘Two Pipe’ single temperature systems or ‘Four Pipe’ independent load systems. The system piping circuit (load distribution circuit) should be basically parallel piping either Direct Return or Reverse Return system with a good pumping arrangement.

The method of circuiting and pumping is a judgment decision by the designer. The designer must weigh the pros and cons of cost, nature of load and configuration of building, energy economics, flexibility, installation requirements and others to determine the best arrangement for his project. In all cases, it must be ensured that the design water flow is constantly maintained through the chillers at all stages of operation. Some suggested arrangements with basic schematic layouts are as follows:

In this type of arrangement, constant water flow through the chillers and load distribution piping circuit is maintained. Before proceeding further, a brief explanation on the operation of a typical chilled water system / valves which is fundamental to the design or analysis of a system.

Where multiple zones of control are required, the various load devices are controlled first; then the source (chillers) system capacity is controlled to follow the capacity requirement of the loads. Control valves are commonly used to control loads. These valves control the capacity of each load by varying the amount of water flow through the load device. Control valves for these applications are two-way (straight-through) and three-way valves. The effect of either valve is to vary the amount of water flowing through the load device. With a two-way valve, as the valve strokes from full-open to fullclosed, the quantity of water flowing through the load gradually decreases from design flow to no flow. The three-way mixing valve has the same effect on the load as the two way valve - as the load reduces, the quantity of water flowing through the load decreases in proportion to the load and the difference amount is directed through a bypass.

In terms of load control, a two-way valve and a three-way valve perform identical functions—they both vary the flow through the load as the load changes. The fundamental difference between the two-way valve and the three-way valve is that as the source or distribution system sees the load, the two-way valve provides a variable flow load response and the three-way valve provides a constant flow load response.

Referring to the foregoing schematic layout, this is a conventional system and is not as energy efficient as the two-way valve systems especially on the pumping side due to constant water circulation in the system. On multiple chiller installations, pumps are required to operate continuously and the sequencing of chillers is dependent on water temperatures.

In this type of arrangement, constant water flow through the chillers is maintained, however the quantity of water flowing through the load distribution piping system decreases in proportion to the load and the difference amount is directed through a bypass pipe that connects the supply and return headers. Brief sequence of operation is as follows:

The bypass with its control valve and flow meter provides the design flow required through the chillers. Flow meter FM1 measures the actual flow to the chilled water system. The system flow is compared with the required flow for the chillers. The difference is made up through the bypass and is monitored by flow meter FM2. This flow meter controls the bypass valve to maintain the desired flow in the bypass based on the set points in the system controller (the valve is positioned by sum of flow meters FM1 and FM2).

The speed of the chiller pumps is controlled by the differential pressure sensor/transmitter, maintaining the desired differential pressure (∆P) across the cooling coils, their control valves and the branch piping. The pump speed is modulated within a certain range in order to reduce the pumping head and not to alter the water flow rate (the duty flow rate of the pumps remains constant). Each chiller-pump combination operates independently from the remaining chillers and each pump is shutdown when the respective chiller is stopped. Instead of using water temperature as an indicator of demand, the sequencing of chillers is dependent on water flow. The chillers are rated in gallons per minute; the actual flow to the system determines the number of chillers that should be in operation.

Energy is saved because the system head is reduced appreciably when there are light cooling loads on the system and due to cycling of pumps.

Note: Some designers may consider installing constant speed pumps and utilize pressure relief bypass control valves controlled by a differential pressure sensor/controller to maintain a fixed differential pressure between the supply and return mains of the chilled water system in order to accommodate for the required chiller flow and to achieve some form of variable volume system. This method is not recommended as it’s a wasteful practice because a considerable amount of energy is lost, an almost constant volume system results and the pumping energy remains substantially that required at full system flow and head.

Also, the problem with this system is improper control of the bypass valve which does not guarantee proper flow through the chillers and high differential pressures in the control valves on the cooling coils when the system friction subsides at low loads which can cause lifting of the valve stems or wire cutting of the valve seats. Further, as all the water must be pumped at a head equal to or greater than the design head, the pump or pumps are forced to run up the pump head capacity curve, which increases the overpressure on the system and also increases the wear on the pumps, since they are forced to operate with high radial thrusts.

This system is called a Primary – Secondary System and in this arrangement, the generation zone is separated from the transportation or distribution zone. In this type of arrangement also, constant water flow through the chillers is maintained, however the quantity of water flowing through the load distribution pump/piping system decreases in proportion to the load and the difference amount is directed through a bypass pipe that connects the supply and return headers. This bypass pipe forms a ‘Hydraulic Coupling’ between the points A – B and is also called as Common Bridge or Decoupling Line. The sequence of operation is similar as the foregoing system with the following explanation:

The speed of the secondary chiller pump is controlled by the differential pressure sensor/transmitter, maintaining the desired differential pressure (∆P) across the cooling coils, their control valves and the branch piping. This pump speed is modulated within a broad range in order to reduce the pumping head and alter the water flow rate based on the changing load conditions.

The primary pumps are constant speed pumps and the design flow rate through the chillers remains constant. Each chiller-pump combination operates independently from the remaining chillers and each pump is shutdown when the respective chiller is stopped. The sequencing of chillers is dependent on water flow. If greater flow is demanded than that supplied by the chiller-pumps, return water is forced through the bypass into the supply header. This flow indicates a need for additional chiller capacity and another chiller-pump starts. Excess bypass flow with reference to the set points in the system controller in the opposite direction i.e., into the return header indicates overcapacity and the chiller-pumps are turned off.

Energy is saved because the system head and water flow rate are reduced on the Secondary Pump when there are partial cooling loads on the system and due to cycling of Primary Pumps.

UNIT LOCATION AND INSTALLATION

These chillers are designed for outdoor installation and can be installed at ground level or on a suitable rooftop location. In order to achieve good operation, performance and trouble-free service, it is essential that the proposed installation location and subsequent installing procedures meet the following requirements:

• The most important consideration while deciding upon the location of air cooled chillers is the provision for supply of adequate ambient air to the condenser and removal of heated discharge air from the condenser. This is accomplished by maintaining sufficient clearances which have been specified in this Catalog around the units and avoiding obstructions in the condenser air discharge area to prevent the possibility of warm air circulation. Further, the condenser fans are propeller type and are not recommended for use with ductwork or other hindrances in the condenser air stream. Where these requirements are not complied, the supply or discharge airflow restrictions or warm air recirculation will cause higher condensing temperatures resulting in poor unit operation, higher power consumption and possible eventual failure of equipment.

Page 41

•

The unit’s longitudinal axis should be parallel to the prevailing wind direction in order to ensure a balanced air flow through the condenser coils. Consideration should also be given to the possibility of down-drafts caused by adjacent buildings, which may cause recirculation or uneven unit airflow. For locations where significant cross winds are expected, an enclosure of solid or louver type is recommended to prevent wind turbulence interfering with the unit airflow. When units are installed in an enclosure, the enclosure height should not exceed the height of the unit.

•

The location should be selected for minimum sun exposure and away from hot air sources, steam, exhaust vents and sources of airborne chemicals that could attack the condenser coils and steel parts of the unit. Avoid locations where the sound output and air discharge from the units may be objectionable.

•

If the location is an area which is accessible to unauthorized persons, steps must be taken to prevent access to the unit by means of a protective fence. This will help to prevent the possibility of vandalism, accidental damage or possible harm caused by unauthorized removal of panels or protective guards exposing rotating or high voltage components.

•

The clearance requirements prescribed above are necessary to maintain good airflow and provide access for unit operation and maintenance. However, it is also necessary to consider access requirements based on practical considerations for servicing, cleaning and replacing large components.

•

The unit must be installed on a ONE-PIECE, FLAT and LEVELLED {within 1/2'' (13 mm) over its length and width} / CONCRETE BASE that extends fully to support the unit. The carrying or supporting structure should be capable of handling complete operating weight of the unit as given in the Physical Data tables in this Catalog.

•

For ground level installations, it must be ensured that the concrete base is stable and does not settle or dislocate upon installation of the unit which can strain the refrigerant lines resulting in leaks and may also cause compressor oil return problems. It is recommended that the concrete slab is provided with appropriate footings. The slab should not be connected to the main building foundation to avoid noise and vibration transmission.

•

For rooftop installations, choose a place with adequate structural strength to safely support the entire operating weight of the unit. The unit shall be mounted on a concrete slab similar to ground installations. The roof must be reinforced for supporting the individual point loads at the mounting isolator locations. It must be checked and ensured that the concrete base is perfectly horizontal and levelled, especially if the roof has been pitched to aid in water removal. It should be determined prior to installation if any special treatment is required to assure a levelled installation else it could lead to the above mentioned problems.

•

Vibration isolators are necessary for installing these chillers in order to minimize the transmission of vibrations. The two types of vibration isolators generally utilized for mounting these units are Neoprene Pads and Spring Isolators. Neoprene Pads are recommended for ground level normal installations jobs where vibration isolation is not critical and job costs must be kept to a minimum. Spring Isolators are recommended for ground level installations which are noisesensitive areas or exposed to wind loads and all roof top installations. For critical installations (extremely noise and vibration sensitive areas), follow the recommendations of structural and acoustical consultants.

•

Based on the specific project requirements, choose the type of vibration isolators best suited for the application. Carefully select the vibration isolators’ models / configuration based on the respective point loads and place each mount in its correct position following the Load Distribution Data and Mounting Drawings provided in this Catalog. Refer to the Schematic Mounting Layout drawings provided in the IOM manual of these chillers for further details in this regard.

COOLER PIPING CONNECTIONS

The following pertinent guidelines are served to ensure satisfactory operation of the units. Failure to follow these recommendations may cause improper operation and loss of performance, damage to the unit and difficulty in servicing and maintenance:

•

Water piping must be connected correctly to the unit i.e., water must enter from the inlet connection on the cooler and leave from the outlet connection.

•

A flow switch must be installed in the field piping at the outlet of the cooler (in horizontal piping) and wired back to the unit control panel using shielded cable. There should be a straight run of piping of at least five pipe diameters on either side of the flow switch. Paddle type flow switches can be obtained from COOLINE which are supplied as optional items.

•

The chilled water pump(s) installed in the piping system should discharge directly into the unit cooler. The pump(s) may be controlled external to the unit - but an interlock must be wired to the unit control panel (as shown in the wiring diagram) so that the unit can start only upon proof of pump operation.

Page 42

•

Flexible connections suitably selected for the fluid and pressure involved should be provided as mandatory in order to minimize transmission of vibrations to the piping / building as some movement of the unit can be expected during normal operation. The piping and fittings must be separately supported to prevent any loading on the cooler.

•

The cooler must be protected by a strainer, preferably of 20 mesh, fitted as close as possible to the liquid inlet connection, and provided with a means of local isolation.

•

Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each cooler. Pressure gauges are recommended to check the water pressure before and after the cooler and to determine if any variations occur in the cooler and system. When installing pressure taps to measure the amount of pressure drop across the water side of the cooler, the taps should be located in the water piping a minimum of 24 inches downstream from any connection (flange etc.) but as near to the cooler as possible.

•

Drain and air vent connections should be provided at all low and high points in the piping system to permit complete drainage of the cooler and piping as well as to vent any air in the pipes. Hand shut-off valves are recommended for use in all lines to facilitate servicing.

•

The system water piping must be flushed thoroughly before connecting to the unit cooler. The cooler must not be exposed to flushing velocities or debris released during flushing. It is recommended that a suitably sized bypass and valve arrangement is installed to allow flushing of the piping system. The bypass can be used during maintenance to isolate the cooler without disrupting flow to other units.

•

The following is a suggested piping arrangement at the chiller for single unit installations. For multiple chiller installations, each unit should be piped as shown:

Isolating Valve - Normally Open

Isolating Valve - Normally Closed

Balancing Valve

Flow meter

Strainer

Pressure tapping

Flow Switch

Connection (flanged / Victaulic)

Note: For chillers with two coolers, the connecting pipes for entering and leaving water on one cooler must be joined to the corresponding pipes on the other cooler before connecting to the main headers in the system piping.

Page 43

CHILLED FLUID VOLUME REQUIREMENT

The volume of water in a piping system loop is critical to the smooth and proper operation of a chilled water system. If sufficient volume of water is not there in the system, the temperature control can be lost resulting in erratic system operation and excessive compressor cycling. Therefore, to prevent this effect of a ‘Short Water Loop’ ensure that total volume of water in the piping system loop equals or exceeds 3 Gallons per Nominal Ton of cooling capacity for standard air conditioning applications and 6 Gallons per Nominal Ton of cooling capacity for process cooling jobs where accuracy is vital and applications requiring operation at very low ambient temperatures and low loading conditions.

For example, chiller model ASQ100B operating with a design water flow rate of 205 GPM for a standard air conditioning application would require 100 (Nom. Cap.) x 3 = 300 Gallons of water in the piping system loop.

To achieve the aforementioned water volume requirements, it may be necessary to install a tank in the piping system loop to increase the volume of water in the system and therefore, reduce the rate of change of return water temperature. This tank should be provided on the return water side to the chiller and the tank should be baffled to ensure that there is no stratification and the entering stream thoroughly mixes with the tank water. See recommended tank design schematics below:

TANK SCHEMATIC

SUGGESTIONS ON SYSTEM DESIGN AND PIPING PRACTICES

The prospective chilled water system should be designed to the specific requirements of the owner and to achieve the most efficient system possible. Following are some recommendations:

•

The first decision a designer of a chilled water system must make is the selection of the temperature differential. Temperature differential is the difference between the supply water and the return water temperatures. There is no one temperature difference for all chilled water systems. The actual temperature difference that is selected for a specific installation is determined by the cost of the cooling coils for various temperature differences and the effect that higher differences may have on the operating cost of the chillers. A careful balance between energy savings and first cost should be made by the designer. These are the decisions that must be made by the designer for each application and only experienced designers should entertain water temperature differences in excess of 12 tems. A number of conditions must be recognized before making the final selection of temperature differential:

a) An increase in temperature differential decreases water flow and therefore saves pumping energy. b) An increase in temperature differential may increase the cost of cooling coils that must operate with a higher mean

temperature difference.

c) Higher temperature differentials increase the possibilities of loss of temperature difference in coils due to dirt on the

air side and chemical deposits on the water side of them.

d) Laminar flow on the water side due to lower velocities at low loads on a coil is always a concern of the water system

designer. The possibility of laminar flow is greater with higher temperature differences. Laminar flow reduces the heat-transfer rate and should not occur in a coil at any point in its load range. Many systems operate inefficiently because of coils that were selected at too low a friction loss through them at design load; therefore, at reduced loads and flows, they operate with laminar flow.

•

Control of Return Water Temperature: Return water temperature is one of the most important operating values for a chilled water system. It tells the operator just how good a job the control system and coils are doing in converting energy from the chillers to the air or water systems that are cooling the building. This is such a basic criterion that it should be addressed early in the design of a chilled water system. The proper method of controlling return temperature is through the correct selection of control valves and cooling coils. In conclusion, one of the designer’s most important tasks is the selection of a sound temperature differential that will provide maximum possible system efficiency. The second step in this process is to ensure that the differential is maintained after the system is commissioned.

•

The water system should be configured to distribute the water efficiently with a minimum use of energy-wasting devices. These devices are listed here:

a) Three-way temperature control valves b) Balancing valves, manual or automatic

c) Pressure-reducing or pressure-regulating valves

•

The piping should be designed without a) Reducing flanges or threaded reducing couplings b) Bullhead connections (e.g., two streams connected to the run connections of a tee with the discharge on the branch

of the tee)

•

The friction for the piping should be calculated for all pipe runs, fittings and valves.

•

Cooling coils should be selected with a high enough water velocity in the tubes to avoid laminar flow throughout the normal load range imposed on the coils.

•

Coil control valves and their actuators should be sized to ensure that they can operate at all loads on the system without lifting the valve head off the valve seat.

•

Expansion tank should be provided to so that water volume changes can be accommodated. Expansion tanks are generally connected to the suction side of the pump - lowest pressure point.

•

Pumps in parallel must always operate at the same speed. There may be some exceptional cases where parallel pumps are operated at different speeds, but only experienced designers should make evaluations for such a proposed operation. Also, it is better to use pumps of the same size when operating them in parallel. Variable speed pumps should be controlled so that pumps operating in parallel never have more than one percent difference in actual operating speed. Mixing of constant and variable speed pumps in parallel operation is wrong and leads to disastrous results.

•

Distribution pumps should be selected for maximum efficiency at the design condition and within the economic constraints of the project. Distribution pumps should be added and subtracted to avoid operation of pumps at points of high thrust and poor efficiency. Pump sequencing should achieve maximum possible system efficiency.

•

Differential pressure control (bypass) valves should never be installed at the pump discharges.

•

Check valves should be provided in pump discharges when pumps are operating in parallel. Pump discharge check valves should be center guided, spring loaded, disc type check valves and should be sized so that the check valve is full open at design flow rate. Generally this will require the check valve to be one pipe size smaller than the connecting piping.

•

Circuiting Chilled water to Multiple Chillers : There are fundamentals for the circuiting of chillers that should not be violated in order to achieve maximum efficiency. Some of these are:

a) Design the piping arrangement so that energy consumption of chillers is not increased.

b) Arrange the piping so that all chillers receive the same return water temperature. c) Ensure that the required design water flow through the coolers is always maintained.

RIGGING INSTRUCTIONS

ATTENTION TO RIGGERS

Hook rigging sling thru holes in base rail, as shown below. Holes in base rail are centered around the unit center of gravity. Center of gravity is not unit center line. Ensure center of gravity aligns with the main lifting point before lifting. Use spreader bar when rigging, to prevent the slings from damaging the unit.

CAUTION

All panels should be in place when rigging. Care must be taken to avoid damage to the coils during handling. Insert packing material between coils & slings as necessary.
