The water flow switch should be calibrated accordingly. install and operate. the decreased air density will reduce condenser capacity and therefore unit capacity. The more scale forming material and suspended solids in the system water. consult Zamil Air Conditioners for specific recommendations. unit capacity decreases and power input increases. When using glycol solution. water flow rate must not vary more than ± 5% from the design flow rate.

In order to prevent corrosion and pitting. install a single chiller for the present load requirement and install a second chiller for the foreseen additional load demand due to expansion. fungi and bacteria). consider using multiple units. Operation of two chillers at higher loading is preferred to operating a single chiller at or near its minimum possible capacity. Over sizing adversely affects the operating efficiency due to erratic system operation and excessive compressor cycling which also results in reduced compressor life. silt. Stable operation.5. For unit selection at other fouling factors. the greater the chances of scale and deposit formation and fouling. The piping and pumping layout should be right for the application and must assure proper water return and circulation. Design flow rates below the minimum limits will result in laminar flow causing freeze-up problems. As fouling factor is increased. In such applications. HIGH AMBIENT CONSIDERATION These chillers are designed for year round operation over a range of ambient temperatures. It should be noted that. 35 . dirt. For example. an oversized unit is usually more costly to purchase. 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. These chillers are suitable for operation with well maintained water systems. silica. Over sizing chillers beyond a maximum limit of 5 – 10 % in order to assure adequate capacity or considering future expansions is not recommended. In addition. When over sizing is desired due to anticipation of future plant expansion. which should be kept to the minimum to retard scale and deposit formation. For unit selection at these higher altitudes. These include calcium. performance and reliability of units is often dependent upon proper compliance with these recommendations. organic contaminants (oils). apply appropriate correction factor from the table provided in this catalog.APPLICATION GUIDELINES INTRODUCTION These guidelines should be considered when designing systems and their installation utilizing Zamil ASY series liquid chillers. magnesium. Zamil recommends that a water treatment specialist is consulted to provide and maintain water treatment. Further. The design water flow rate must be within this range. clays. As a standard.000018 m2-0C/W). the pH value of the water flowing through the cooler must be kept between 7 and 8. The Zamil electronic selection program may also be utilized for this purpose. FOULING FACTOR AND WATER REQUIREMENT The tabulated performance data provided in this catalog are based on a fouling factor of 0. apply appropriate correction factor from the table provided in this catalog. When any application varies from these guidelines. etc. therefore care must be taken not to exceed the limits. At altitudes substantially above sea level. EFFECT OF ALTITUDE ON UNIT CAPACITY The tabulated performance data provided in this catalog are for use at or near sea level altitude application. 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. During unit operation. flow rate and pressure drop are higher than with water. stratification and poor control and flow rates beyond the maximum limits cause excessive pressure drop and severe tube erosion. 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. 8 GPM 65°F 192 GPM Load 120 TR 80°F 109. The design leaving chilled fluid temperature (LCWT) range as mentioned earlier in the tabulated performance data is 40 to 500F. Example 1: An application requires 240 GPM of water at 450F and the return water temperature is 650F. The design entering chilled fluid temperature range is 50 to 600F. A standard chiller can be used for this application as shown in the following basic schematic layout (single mixing arrangement).2 GPM 45°F 257.2 GPM 36 80°F 192 GPM .

A standard chiller can be used for this application as shown in the following basic schematic layout (dual mixing arrangement).COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGE Unit can start and pull down from 950F (350C) entering fluid temperature. 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. The design cooler temperature drop (ΔT) range is 5 to 150F. 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 Zamil 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. Also. energy economics. It is also possible to achieve higher overall entering to leaving temperature drops. In all cases.COOLER FREEZE PROTECTION If the unit is located in an area where ambient temperatures fall below 320F (00C). This glycol solution must be added to the water system loop to bring down the freezing point of water to a difference of 150F (8.. flow rate and pressure drop. Series chiller arrangements can be controlled in several ways based on the water temperatures depending on cooling demand. as well as power costs at partial-load conditions. they offer some standby capacity if repair work must be done on a chiller from a set of duty chillers. Parallel arrangements permit adding chillers in the future for plant expansion with the appropriate considerations beforehand. Complete design details on these parallel and series chilled water flow arrangements can be found in the ASHRAE handbooks and other design literature which should be referred by the designer in preparing his detailed designs. installation requirements and others to determine the best arrangement for his project. lower design flow and resulting installation and operational cost savings. flexibility. it must be ensured that the design water flow is constantly maintained through the chillers at all stages of operation. In the series arrangement. nature of load and configuration of building. Zamil recommends the parallel arrangement for design temperature drops (ΔT) up to 150F and the series arrangement beyond that i. therefore appropriate correction factors from the aforementioned table in this catalog should be applied. the chilled liquid pressure drop may be higher unless coolers with fewer liquid-side passes or baffles are used. and compressor power consumption is lower than it is for the parallel arrangement at partial loads. standby capacity and less disruptive maintenance. PIPING ARRANGEMENTS AND PLANT LAYOUT Our chillers are suitable for incorporating in ‘Two Pipe’ single temperature systems or ‘Four Pipe’ independent load systems. Using this glycol solution causes a variation in unit performance. Starting in-rush current is reduced.30C) below minimum operating ambient temperature. liquid to be chilled is divided among the liquid chillers. cooler protection in the form of Ethylene Glycol Solution is required to protect the cooler and fluid piping from low ambient freeze-up. Water temperatures (EWT or LWT) can be used to cycle units On and Off based on the cooling demand. The system piping circuit (load distribution circuit) should be basically parallel piping either Direct Return or Reverse Return system with a good pumping arrangement. units of same size should be preferred over different sizes to facilitate balanced water flow. two basic multiple chiller systems are used: parallel and series chilled water flow. 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. large temperature drop (greater than 150F) is desired or application calls for splitting the total capacity for better part load operation. It is mandatory that cooler flow rates must be balanced to ensure proper flow to each chiller based on its respective capacity.e. In designing a multiple chiller plant. The designer must weigh the pros and cons of cost. the multiple chilled streams are combined again in a common line after chilling. Multiple chiller arrangements offer the advantage of operational flexibility. 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. The method of circuiting and pumping is a judgment decision by the designer. In the parallel arrangement. A multiple chiller arrangement should be provided if the system load is greater than a single chiller capacity. No over chilling by either unit is required. standby capability is desired. which may in turn provide the opportunity for lower chilled water design temperature. Some suggested arrangements with basic schematic layouts are as follows: 37 . As mentioned above. 16 to 200F. These valves control the capacity of each load by varying the amount of water flow through the load device. the various load devices are controlled first. 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. The effect of either valve is to vary the amount of water flowing through the load device. Where multiple zones of control are required. the quantity of water flowing through the load decreases in proportion to the load and the difference amount is directed through a bypass. Referring to the foregoing schematic layout. as the valve strokes from full-open to fullclosed. Control valves for these applications are two-way (straight-through) and three-way valves. the two-way valve provides a variable flow load response and the three-way valve provides a constant flow load response. a brief explanation on the operation of a typical chilled water system / valves which is fundamental to the design or analysis of a system. 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 quantity of water flowing through the load gradually decreases from design flow to no flow.as the load reduces. 38 . In terms of load control. constant water flow through the chillers and load distribution piping circuit is maintained.A. The three-way mixing valve has the same effect on the load as the two way valve . Single or multiple chillers with constant water flow through chillers and load system: CHWS Load Chiller 3-Way Valve Load 3-Way Valve CHWR Constant Speed Pump In this type of arrangement. then the source (chillers) system capacity is controlled to follow the capacity requirement of the loads. pumps are required to operate continuously and the sequencing of chillers is dependent on water temperatures. With a two-way valve. On multiple chiller installations. Before proceeding further. The fundamental difference between the two-way valve and the three-way valve is that as the source or distribution system sees the load. Control valves are commonly used to control loads. Each chiller-pump combination operates independently from the remaining chillers and each pump is shutdown when the respective chiller is stopped. 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. 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. since they are forced to operate with high radial thrusts. This bypass pipe forms a ‘Hydraulic Coupling’ between the points A – B and is also called as Common Bridge or Decoupling Line. The primary pumps are constant speed pumps and the design flow rate through the chillers remains constant. If greater flow is demanded than that supplied by the chiller-pumps.B. an almost constant volume system results and the pumping energy remains substantially that required at full system flow and head. constant water flow through the chillers is maintained. Further. maintaining the desired differential pressure (ΔP) across the cooling coils. The sequencing of chillers is dependent on water flow. This method is not recommended as it’s a wasteful practice because a considerable amount of energy is lost. In this type of arrangement also. into the return header indicates overcapacity and the chiller-pumps are turned off. 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. Single or multiple chillers with constant water flow through chillers and variable water flow through load system (primary/secondary pumping arrangement): CHWS A Variable Speed Secondary Pump Load Load Chiller Flow Sensor P 2-Way Valve 2-Way Valve Constant Speed Primary Pump B CHWR System Controller This system is called a Primary – Secondary System and in this arrangement. which increases the overpressure on the system and also increases the wear on the pumps. their control valves and the branch piping. return water is forced through the bypass into the supply header. the pump or pumps are forced to run up the pump head capacity curve.e. 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. as all the water must be pumped at a head equal to or greater than the design head. 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. the generation zone is separated from the transportation or distribution zone. Also. 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. 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. 39 .. • The clearance requirements prescribed above are necessary to maintain good airflow and provide access for unit operation and maintenance. The slab should not be connected to the main building foundation to avoid noise and vibration transmission. steps must be taken to prevent access to the unit by means of a protective fence. performance and trouble-free service. • The unit must be installed on a ONE-PIECE. follow the recommendations of structural and acoustical consultants. 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. the enclosure height should not exceed the height of the unit. especially if the roof has been pitched to aid in water removal. • The location should be selected for minimum sun exposure and away from hot air sources. 40 . the condenser fans are propeller type and are not recommended for use with ductwork or other hindrances in the condenser air stream. Avoid locations where the sound output and air discharge from the units may be objectionable. which may cause recirculation or uneven unit airflow. Consideration should also be given to the possibility of down-drafts caused by adjacent buildings. 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. the supply or discharge airflow restrictions or warm air recirculation will cause higher condensing temperatures resulting in poor unit operation. 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. 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. The roof must be reinforced for supporting the individual point loads at the mounting isolator locations. • For rooftop installations. For critical installations (extremely noise and vibration sensitive areas). In order to achieve good operation. • Vibration isolators are necessary for installing these chillers in order to minimize the transmission of vibrations. Spring Isolators are recommended for ground level installations which are noise-sensitive areas or exposed to wind loads and all roof top installations. For locations where significant cross winds are expected. However. exhaust vents and sources of airborne chemicals that could attack the condenser coils and steel parts of the unit. choose the type of vibration isolators best suited for the application. Further. • For ground level installations. an enclosure of solid or louver type is recommended to prevent wind turbulence interfering with the unit airflow.UNIT LOCATION AND INSTALLATION These chillers are designed for outdoor installation and can be installed at ground level or on a suitable rooftop location. It is recommended that the concrete slab is provided with appropriate footings. choose a place with adequate structural strength to safely support the entire operating weight of the unit. 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. FLAT and LEVELLED {within 1/2'' (13 mm) over its length and width} / CONCRETE BASE that extends fully to support the unit. When units are installed in an enclosure. 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. • Based on the specific project requirements. Where these requirements are not complied. The unit shall be mounted on a concrete slab similar to ground installations. The two types of vibration isolators generally utilized for mounting these units are Neoprene Pads and Spring Isolators. • If the location is an area which is accessible to unauthorized persons. It must be checked and ensured that the concrete base is perfectly horizontal and levelled. higher power consumption and possible eventual failure of equipment. Refer to the Schematic Mounting Layout drawings provided in the IOM manual of these chillers for further details in this regard. it is also necessary to consider access requirements based on practical considerations for servicing. accidental damage or possible harm caused by unauthorized removal of panels or protective guards exposing rotating or high voltage components. 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. steam. This will help to prevent the possibility of vandalism. cleaning and replacing large components. • 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. water must enter from the inlet connection on the cooler and leave from the outlet connection. • The cooler must be protected by a strainer. • Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each cooler. The pump(s) may • be controlled external to the unit .Normally Open Pressure tapping Isolating Valve .Normally Closed Flow Switch Balancing Valve Connection (flanged / Victaulic) Flow meter Pipe work Strainer Flexible connection Note: For chillers with two coolers. fitted as close as possible to the liquid inlet connection. Paddle type flow switches can be obtained from Zamil which are supplied as optional items. 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.e. It is recommended that a suitably sized bypass and valve arrangement is installed to allow flushing of the piping system. The cooler must not be exposed to flushing velocities or debris released during flushing.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. 41 . • 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. • The following is a suggested piping arrangement at the chiller for single unit installations. There should be a straight run of piping of at least five pipe diameters on either side of the flow switch. the taps should be located in the water piping a minimum of 24 inches downstream from any connection (flange etc. • 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. • The chilled water pump(s) installed in the piping system should discharge directly into the unit cooler.) but as near to the cooler as possible. For multiple chiller installations. 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. The bypass can be used during maintenance to isolate the cooler without disrupting flow to other units. The piping and fittings must be separately supported to prevent any loading on the cooler. When installing pressure taps to measure the amount of pressure drop across the water side of the cooler. and provided with a means of local isolation. damage to the unit and difficulty in servicing and maintenance: • Water piping must be connected correctly to the unit i.. each unit should be piped as shown: OUT IN Isolating Valve . • The system water piping must be flushed thoroughly before connecting to the unit cooler. 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. preferably of 20 mesh. Hand shut-off valves are recommended for use in all lines to facilitate servicing. Failure to follow these recommendations may cause improper operation and loss of performance.COOLER PIPING CONNECTIONS The following pertinent guidelines are served to ensure satisfactory operation of the units. at reduced loads and flows. 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. it may be necessary to install a tank in the piping system loop to increase the volume of water in the system and therefore. To achieve the aforementioned water volume requirements. reduce the rate of change of return water temperature. 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. 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. Laminar flow reduces the heat-transfer rate and should not occur in a coil at any point in its load range. If sufficient volume of water is not there in the system. Cap. 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. 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 120F on chilled water systems. For example. Many systems operate inefficiently because of coils that were selected at too low a friction loss through them at design load. 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.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. Temperature differential is the difference between the supply water and the return water temperatures. Therefore. chiller model ASY100 operating with a design water flow rate of 205 GPM for a standard air conditioning application would require 100 (Nom.) x 3 = 300 Gallons of water in the piping system loop. A careful balance between energy savings and first cost should be made by the designer. The possibility of laminar flow is greater with higher temperature differences. Following are some recommendations: • The first decision a designer of a chilled water system must make is the selection of the temperature differential. the temperature control can be lost resulting in erratic system operation and excessive compressor cycling. 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. they operate with laminar flow. There is no one temperature difference for all chilled water systems. 42 . therefore. 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. Some of these are: a) Design the piping arrangement so that energy consumption of chillers is not increased. • Expansion tank should be provided to so that water volume changes can be accommodated. but only experienced designers should make evaluations for such a proposed operation. The second step in this process is to ensure that the differential is maintained after the system is commissioned. • 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. Pump discharge check valves should be center guided. spring loaded. • Pumps in parallel must always operate at the same speed. 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. 43 . c) Ensure that the required design water flow through the coolers is always maintained. • 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. This is such a basic criterion that it should be addressed early in the design of a chilled water system.• Control of Return Water Temperature: Return water temperature is one of the most important operating values for a chilled water system. Mixing of constant and variable speed pumps in parallel operation is wrong and leads to disastrous results. fittings and valves.g.lowest pressure point. Variable speed pumps should be controlled so that pumps operating in parallel never have more than one percent difference in actual operating speed.. • The water system should be configured to distribute the water efficiently with a minimum use of energy-wasting devices. b) Arrange the piping so that all chillers receive the same return water temperature. Also. In conclusion. it is better to use pumps of the same size when operating them in parallel. Pump sequencing should achieve maximum possible system efficiency. • Check valves should be provided in pump discharges when pumps are operating in parallel. Generally this will require the check valve to be one pipe size smaller than the connecting piping. The proper method of controlling return temperature is through the correct selection of control valves and cooling coils. Expansion tanks are generally connected to the suction side of the pump . • 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. There may be some exceptional cases where parallel pumps are operated at different speeds. • Differential pressure control (bypass) valves should never be installed at the pump discharges. 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. These devices are listed here: a) Three-way temperature control valves b) Balancing valves. disc type check valves and should be sized so that the check valve is full open at design flow rate. one of the designer’s most important tasks is the selection of a sound temperature differential that will provide maximum possible system efficiency. 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.
