DESIGN REQUIREMENTSThe following design requirements must be known to select a package chiller.1. Required cooling capacity in tons2. Leaving chilled water temperature in 0F (LCWT)3. Chilled water flow rate in GPM4. Chilled water cooling range in 0F (water in temp. _ water out temp.)5. Design ambient temperature6. Minimum ambient temperature7. Altitude8. Electrical power supply
SAMPLE SELECTIONSelect an Air Cooled Packaged chiller for the following conditions:Required system capacity is 115 tons at 540F entering chilled waterand 440F leaving water. Design ambient temperature is 950F.Altitude is 2000 feet above sea level.Water cooler fouling factor is 0.00010. Power supply: 380V-3Ph-60Hz.
STEP-1: UNIT SELECTION
Entering the capacity performance data at given LCWT and ambient temperature.ASY120B chiller unit at sea level will produce 116.5 tons and 129.3 kW compressorpower input at 440F leaving chilled water temperature with 100F water temperaturedifference and 950F ambient temperature.
For the conditions required, the unit actual cooling capacity when corrected foraltitude (0.99) and fouling factor (1.0).Capacity = 116.5x0.99x1.0 = 115.3 Tons, which then exceeds the requirements.So the selection is correct.
STEP-2: CHILLED WATER FLOW (GPM):
Water GPM = Required capacity (Tons) x 24
= 115 x 24
= 276 GPM Cooling Range, ∆T 100F

Referring to pressure drop chart (page # 23), pressure drop at 276 GPM = 17 ft. of water for selected model.
NOTE: The total flow rate should be divided by 2 for models ASY250B - ASY500B to find out the total pressure drop.
STEP-3: ELECTRICAL
Refer to electrical data at 380V-3Ph-60Hz, the main power wire size for ASY120B is to be sized for a minimum circuitampacity (MCA) of 311 Amps and maximum over current protection (MOCP) of 437 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 dropcalculated 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 100F and subtract correction from design leaving chilled water temperature (LCWT) when watertemperature range is below 100F.
EXAMPLE:If LCWT rise is 12.50F, enter correction curve at 12.50F and read the correction factor of 0.2. The corrected LCWT is44+0.2 = 44.20F.
NOTE: 1.When the chilled water temperature rise is less than 50F, the high water flow rate will result to excessivepressure drop. In such cases, contact factory for special selection of a cooler with wider baffle spacing.
2.Please refer to water pressure drop curves.

DESIGN REQUIREMENTSThe following design requirements must be known to select a proper package chiller.1. Required cooling capacity in kilowatt (kW)2. Leaving chilled water temperature in 0C (LCWT)3. Chilled water flow rate in LPS4. Chilled water cooling range in 0C (water in temp. _ water out temp.)5. Design ambient temperature6. Minimum ambient temperature7. Altitude8. Electrical power supply
SAMPLE SELECTIONSelect an Air Cooled Packaged chiller for the following conditions:Required system capacity is 390 kW at 120C entering chilled waterand 60C leaving water. Design ambient temperature is 350C.Altitude is 600 meter above sea level.Water cooler fouling factor is 0.000018. Power supply: 380V-3Ph-60Hz.
STEP-1: UNIT SELECTION
Entering the capacity performance data at given LCWT and ambient temperature.ASY120B chiller unit at sea level will produce 407.9 kW and 129.1 kW compressorpower input at 60C leaving chilled water temperature with 60C water temperaturedifference and 350C ambient temperature.
For the conditions required, the unit actual cooling capacity when corrected foraltitude (0.99) and fouling factor (1.0).Capacity = 407.9x0.99X1.0 = 403.8 kW, which then exceeds the requirements.So the selection is correct.
STEP-2: CHILLED WATER FLOW (LPS):
Water LPS = Required capacity (kW) x 0.239

For chilled water pump selection, add all pressure drop in the closed chilled water loop piping to the pressure dropcalculated 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 60C and subtract correction from design leaving chilled water temperature (LCWT) when watertemperature range is below 60C.
EXAMPLE:If LCWT rise is 7.40C, enter correction curve at 7.40C and read the correction factor of 0.11. The corrected LCWT is60C+0.11 = 6.110C.
NOTE: 1.When the chilled water temperature rise is less than 30C, the high water flow rate will result to excessivepressure 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 CONTROLLERSequence of operationThe 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 SEQUENCEStaging 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 #1liquid line solenoid & slider control valves shall be switched ON. Now the compressor is in the minimum or unloadedcapacity. 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 setpoint. 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 #2liquid line solenoid & slider control valves shall be switched ON. Now the compressor is in the minimum or unloadedcapacity. 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 setpoint. If the discharge pressure falls below the fan stage-OFF set point value, the corresponding fans will turn off.
STAGE - OFF SEQUENCEDuring 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 temperatureset 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 GUIDELINESINTRODUCTIONThese guidelines should be considered when designing systems and their installation utilizing Zamil ASY series liquidchillers. Stable operation, performance and reliability of units is often dependent upon proper compliance with theserecommendations. When any application varies from these guidelines, it should be referred with Zamil Air Conditionersfor specific recommendations.
UNIT SELECTION/SIZINGUnit selection procedure and capacities are provided in this catalog for proper selection. The Zamil electronic selectionprogram 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 futureexpansions is not recommended. Over sizing adversely affects the operating efficiency due to erratic system operationand excessive compressor cycling which also results in reduced compressor life. It should be noted that, units operatemore efficiently when fully loaded rather than larger equipment operating at partial capacities. In addition, an oversizedunit 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 demanddue to expansion. Further, it is also recommended that installing two chillers instead of a single chiller be considered inapplications 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 REQUIREMENTThe 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, applyappropriate 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 mayresult in scale and deposit formation causing reduced cooler efficiency or heat transfer and corrosion or pitting leading topossible equipment damage. The more scale forming material and suspended solids in the system water, the greater thechances of scale and deposit formation and fouling. These include calcium, magnesium, biological growth (algae, fungiand bacteria), dirt, silt, clays, organic contaminants (oils), silica, etc. which should be kept to the minimum to retard scaleand deposit formation. In order to prevent corrosion and pitting, the pH value of the water flowing through the cooler mustbe kept between 7 and 8.5. Zamil recommends that a water treatment specialist is consulted to provide and maintainwater treatment, this is particularly critical with glycol systems.
EFFECT OF ALTITUDE ON UNIT CAPACITYThe tabulated performance data provided in this catalog are for use at or near sea level altitude application. At altitudessubstantially above sea level, the decreased air density will reduce condenser capacity and therefore unit capacity. For unitselection at these higher altitudes, apply appropriate correction factor from the table provided in this catalog.
HIGH AMBIENT CONSIDERATIONThese chillers are designed for year round operation over a range of ambient temperatures. As a standard, these chillerscan start and operate satisfactorily up to 1250F (520C) ambient temperature at rated nominal voltage.
WATER FLOW RATES AND COOLER PRESSURE DROPThe 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 laminarflow causing freeze-up problems, stratification and poor control and flow rates beyond the maximum limits cause exces-sive 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 becalibrated accordingly. The piping and pumping layout should be right for the application and must assure proper water returnand circulation. When using glycol solution, flow rate and pressure drop are higher than with water, therefore care must betaken not to exceed the limits. In such applications, consult Zamil Air Conditioners for specific recommendations.
35
COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGEUnit 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 fluidtemperature 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 maybe operated at any desired temperature drop within the range of 5 to 150F as long as the temperature and flow limits arenot violated and appropriate correction factors are applied on the capacity and power input. The Zamil electronic selec-tion 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 ofcontrol and could adversely affect the functioning of microprocessor controller and may also prove to be detrimental for theequipment.
FLOW RATES AND/OR WATER TEMPERATURES OUT OF RANGECertain applications (particularly process cooling jobs) call for flow rates and/or water temperatures that are outside theabove mentioned limits/range. Our chillers can be utilized for these applications by selecting the chiller based on thespecific process load and making a suitable piping and mixing arrangement in order to bring the flow rates and/or watertemperatures 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 arrange-ment).
Example 2:An application requires 192 GPM of water at 650F and the return water temperature is 800F.A standard chiller can be used for this application as shown in the following basic schematic layout (dual mixing arrangement).

COOLER FREEZE PROTECTIONIf the unit is located in an area where ambient temperatures fall below 320F (00C), cooler protection in the form of EthyleneGlycol Solution is required to protect the cooler and fluid piping from low ambient freeze-up. This glycol solution must beadded to the water system loop to bring down the freezing point of water to a difference of 150F (8.30C) below minimumoperating ambient temperature.
Using this glycol solution causes a variation in unit performance, flow rate and pressure drop, therefore appropriatecorrection factors from the aforementioned table in this catalog should be applied.
MULTIPLE CHILLER ARRANGEMENT OR PLANT CONFIGURATIONA 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 mainte-nance. Also, they offer some standby capacity if repair work must be done on a chiller from a set of duty chillers. Startingin-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, standbycapability is desired, large temperature drop (greater than 150F) is desired or application calls for splitting the totalcapacity for better part load operation.
In designing a multiple chiller plant, units of same size should be preferred over different sizes to facilitate balanced waterflow. It is mandatory that cooler flow rates must be balanced to ensure proper flow to each chiller based on its respectivecapacity. 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 arecombined again in a common line after chilling. Water temperatures (EWT or LWT) can be used to cycle units On and Offbased on the cooling demand. Parallel arrangements permit adding chillers in the future for plant expansion with theappropriate considerations beforehand.
In the series arrangement, the chilled liquid pressure drop may be higher unless coolers with fewer liquid-side passes orbaffles are used. No over chilling by either unit is required, and compressor power consumption is lower than it is for theparallel 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 resultinginstallation and operational cost savings. Series chiller arrangements can be controlled in several ways based on thewater temperatures depending on cooling demand.
A valved piping bypass is suggested around each chiller to facilitate future servicing as it gives the personnel an optionfor service without a complete shutdown.
Zamil recommends the parallel arrangement for design temperature drops (∆T) up to 150F and the series arrangementbeyond that i.e., 16 to 200F. Complete design details on these parallel and series chilled water flow arrangements can befound in the ASHRAE handbooks and other design literature which should be referred by the designer in preparing hisdetailed designs.
PIPING ARRANGEMENTS AND PLANT LAYOUTOur chillers are suitable for incorporating in ‘Two Pipe’ single temperature systems or ‘Four Pipe’ independent loadsystems. The system piping circuit (load distribution circuit) should be basically parallel piping either Direct Return orReverse 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 andcons of cost, nature of load and configuration of building, energy economics, flexibility, installation requirements andothers to determine the best arrangement for his project. In all cases, it must be ensured that the design water flow isconstantly maintained through the chillers at all stages of operation. Some suggested arrangements with basic sche-matic layouts are as follows:
37
A. Single or multiple chillers with constant water flow through chillers and load system:
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 funda-mental 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 controlloads. 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 tovary the amount of water flowing through the load device. With a two-way valve, as the valve strokes from full-open to full-closed, the quantity of water flowing through the load gradually decreases from design flow to no flow. The three-waymixing valve has the same effect on the load as the two way valve - as the load reduces, the quantity of water flowingthrough 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 flowthrough the load as the load changes. The fundamental difference between the two-way valve and the three-way valve isthat as the source or distribution system sees the load, the two-way valve provides a variable flow load response and thethree-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-wayvalve systems especially on the pumping side due to constant water circulation in the system. On multiple chiller instal-lations, pumps are required to operate continuously and the sequencing of chillers is dependent on water temperatures.

B. Single or multiple chillers with constant water flow through chillers and variable water flow through load system:
In this type of arrangement, constant water flow through the chillers is maintained, however the quantity of water flowingthrough the load distribution piping system decreases in proportion to the load and the difference amount is directedthrough 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 FM1measures 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 bypassvalve to maintain the desired flow in the bypass based on the set points in the system controller (the valve is positionedby sum of flow meters FM1 and FM2).
The speed of the chiller pumps is controlled by the differential pressure sensor/transmitter, maintaining the desireddifferential pressure (∆P) across the cooling coils, their control valves and the branch piping. The pump speed is modu-lated within a certain range in order to reduce the pumping head and not to alter the water flow rate (the duty flow rate ofthe pumps remains constant). Each chiller-pump combination operates independently from the remaining chillers andeach pump is shutdown when the respective chiller is stopped. Instead of using water temperature as an indicator ofdemand, the sequencing of chillers is dependent on water flow. The chillers are rated in gallons per minute; the actualflow 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 anddue to cycling of pumps.
Note: Some designers may consider installing constant speed pumps and utilize pressure relief bypass control valvescontrolled by a differential pressure sensor/controller to maintain a fixed differential pressure between the supply andreturn mains of the chilled water system in order to accommodate for the required chiller flow and to achieve some formof variable volume system. This method is not recommended as it’s a wasteful practice because a considerable amountof energy is lost, an almost constant volume system results and the pumping energy remains substantially that requiredat full system flow and head.
Also, the problem with this system is improper control of the bypass valve which does not guarantee proper flow throughthe chillers and high differential pressures in the control valves on the cooling coils when the system friction subsides atlow loads which can cause lifting of the valve stems or wire cutting of the valve seats. Further, as all the water must bepumped at a head equal to or greater than the design head, the pump or pumps are forced to run up the pump headcapacity curve, which increases the overpressure on the system and also increases the wear on the pumps, since theyare forced to operate with high radial thrusts.

C. Single or multiple chillers with constant water flow through chillers and variable water flow through loadsystem (primary/secondary pumping arrangement):
This system is called a Primary – Secondary System and in this arrangement, the generation zone is separated from thetransportation or distribution zone. In this type of arrangement also, constant water flow through the chillers is main-tained, however the quantity of water flowing through the load distribution pump/piping system decreases in proportion tothe load and the difference amount is directed through a bypass pipe that connects the supply and return headers. Thisbypass pipe forms a ‘Hydraulic Coupling’ between the points A – B and is also called as Common Bridge or DecouplingLine. 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 thedesired differential pressure (∆P) across the cooling coils, their control valves and the branch piping. This pump speed ismodulated within a broad range in order to reduce the pumping head and alter the water flow rate based on the changingload conditions.
The primary pumps are constant speed pumps and the design flow rate through the chillers remains constant. Eachchiller-pump combination operates independently from the remaining chillers and each pump is shutdown when therespective chiller is stopped. The sequencing of chillers is dependent on water flow. If greater flow is demanded than thatsupplied by the chiller-pumps, return water is forced through the bypass into the supply header. This flow indicates aneed for additional chiller capacity and another chiller-pump starts. Excess bypass flow with reference to the set points inthe system controller in the opposite direction i.e., into the return header indicates overcapacity and the chiller-pumps areturned off.
Energy is saved because the system head and water flow rate are reduced on the Secondary Pump when there arepartial cooling loads on the system and due to cycling of Primary Pumps.
UNIT LOCATION AND INSTALLATIONThese 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 installationlocation 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 ofadequate ambient air to the condenser and removal of heated discharge air from the condenser. This is accomplishedby maintaining sufficient clearances which have been specified in this Catalog around the units and avoiding obstruc-tions in the condenser air discharge area to prevent the possibility of warm air circulation. Further, the condenser fansare 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 willcause higher condensing temperatures resulting in poor unit operation, higher power consumption and possible even-tual failure of equipment.

• The unit’s longitudinal axis should be parallel to the prevailing wind direction in order to ensure a balanced air flowthrough the condenser coils. Consideration should also be given to the possibility of down-drafts caused by adjacentbuildings, which may cause recirculation or uneven unit airflow. For locations where significant cross winds are ex-pected, 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 andsources of airborne chemicals that could attack the condenser coils and steel parts of the unit. Avoid locations wherethe 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 unitby means of a protective fence. This will help to prevent the possibility of vandalism, accidental damage or possibleharm 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 unitoperation and maintenance. However, it is also necessary to consider access requirements based on practical consid-erations 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 ofhandling 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 uponinstallation of the unit which can strain the refrigerant lines resulting in leaks and may also cause compressor oil returnproblems. It is recommended that the concrete slab is provided with appropriate footings. The slab should not beconnected 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 weightof the unit. The unit shall be mounted on a concrete slab similar to ground installations. The roof must be reinforced forsupporting the individual point loads at the mounting isolator locations. It must be checked and ensured that theconcrete base is perfectly horizontal and levelled, especially if the roof has been pitched to aid in water removal. Itshould be determined prior to installation if any special treatment is required to assure a levelled installation else itcould lead to the above mentioned problems.
• Vibration isolators are necessary for installing these chillers in order to minimize the transmission of vibrations. Thetwo 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 andjob costs must be kept to a minimum. Spring Isolators are recommended for ground level installations which are noise-sensitive areas or exposed to wind loads and all roof top installations. For critical installations (extremely noise andvibration 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 eachmount 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 thisregard.
COOLER PIPING CONNECTIONSThe following pertinent guidelines are served to ensure satisfactory operation of the units. Failure to follow these recom-mendations may cause improper operation and loss of performance, damage to the unit and difficulty in servicing andmaintenance:
• Water piping must be connected correctly to the unit i.e., water must enter from the inlet connection on the cooler andleave 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 theunit control panel using shielded cable. There should be a straight run of piping of at least five pipe diameters on eitherside of the flow switch. Paddle type flow switches can be obtained from Zamil 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 wiringdiagram) so that the unit can start only upon proof of pump operation.
41
• Flexible connections suitably selected for the fluid and pressure involved should be provided as mandatory in order tominimize transmission of vibrations to the piping / building as some movement of the unit can be expected duringnormal 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 connec-tion, 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 anyvariations occur in the cooler and system. When installing pressure taps to measure the amount of pressure dropacross the water side of the cooler, the taps should be located in the water piping a minimum of 24 inches downstreamfrom 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 completedrainage of the cooler and piping as well as to vent any air in the pipes. Hand shut-off valves are recommended for usein all lines to facilitate servicing.
• The system water piping must be flushed thoroughly before connecting to the unit cooler. The cooler must not beexposed to flushing velocities or debris released during flushing. It is recommended that a suitably sized bypass andvalve arrangement is installed to allow flushing of the piping system. The bypass can be used during maintenance toisolate 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 installa-tions, each unit should be piped as shown:
Note: For chillers with two coolers, the connecting pipes for entering and leaving water on one cooler must be joined tothe corresponding pipes on the other cooler before connecting to the main headers in the system piping.

CHILLED FLUID VOLUME REQUIREMENTThe volume of water in a piping system loop is critical to the smooth and proper operation of a chilled water system. Ifsufficient volume of water is not there in the system, the temperature control can be lost resulting in erratic systemoperation and excessive compressor cycling. Therefore, to prevent this effect of a ‘Short Water Loop’ ensure that totalvolume of water in the piping system loop equals or exceeds 3 Gallons per Nominal Ton of cooling capacity for standardair conditioning applications and 6 Gallons per Nominal Ton of cooling capacity for process cooling jobs where accuracyis vital and applications requiring operation at very low ambient temperatures and low loading conditions.
For example, chiller model ASY100 operating with a design water flow rate of 205 GPM for a standard air conditioningapplication 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 systemloop 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 isno stratification and the entering stream thoroughly mixes with the tank water. See recommended tank design schemat-ics below:
SUGGESTIONS ON SYSTEM DESIGN AND PIPING PRACTICESThe prospective chilled water system should be designed to the specific requirements of the owner and to achieve themost 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 onetemperature difference for all chilled water systems. The actual temperature difference that is selected for a specificinstallation is determined by the cost of the cooling coils for various temperature differences and the effect that higherdifferences may have on the operating cost of the chillers. A careful balance between energy savings and first costshould be made by the designer. These are the decisions that must be made by the designer for each application andonly experienced designers should entertain water temperature differences in excess of 120F on chilled water sys-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 meantemperature difference.
c) Higher temperature differentials increase the possibilities of loss of temperature difference in coils due to dirt on theair 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 systemdesigner. The possibility of laminar flow is greater with higher temperature differences. Laminar flow reduces theheat-transfer rate and should not occur in a coil at any point in its load range. Many systems operate inefficientlybecause of coils that were selected at too low a friction loss through them at design load; therefore, at reducedloads and flows, they operate with laminar flow.

• Control of Return Water Temperature: Return water temperature is one of the most important operating values for achilled water system. It tells the operator just how good a job the control system and coils are doing in convertingenergy from the chillers to the air or water systems that are cooling the building. This is such a basic criterion that itshould be addressed early in the design of a chilled water system. The proper method of controlling return temperatureis through the correct selection of control valves and cooling coils. In conclusion, one of the designer’s most importanttasks is the selection of a sound temperature differential that will provide maximum possible system efficiency. Thesecond 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-wastingdevices. 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 branchof 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 thenormal 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 systemwithout lifting the valve head off the valve seat.
• Expansion tank should be provided to so that water volume changes can be accommodated. Expansion tanks aregenerally 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 parallelpumps are operated at different speeds, but only experienced designers should make evaluations for such a proposedoperation. Also, it is better to use pumps of the same size when operating them in parallel. Variable speed pumpsshould be controlled so that pumps operating in parallel never have more than one percent difference in actual oper-ating speed. Mixing of constant and variable speed pumps in parallel operation is wrong and leads to disastrousresults.
• Distribution pumps should be selected for maximum efficiency at the design condition and within the economic con-straints of the project. Distribution pumps should be added and subtracted to avoid operation of pumps at points ofhigh 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 checkvalves should be center guided, spring loaded, disc type check valves and should be sized so that the check valve isfull open at design flow rate. Generally this will require the check valve to be one pipe size smaller than the connectingpiping.
• Circuiting Chilled water to Multiple Chillers : There are fundamentals for the circuiting of chillers that should not beviolated 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.
