Product Manual WHR WHR 017EW - 210EW 3 Features and Benefits

Efficiency All units are in full compliance with ASHRAE 90-1. Operating economy at reduced load is increased by operating each refrigerant circuit partially unloaded, rather than one circuit off and the other circuit fully loaded. At unloaded conditions each compressor will operate at lower compression ratios with substantial power savings. Optional steps of capacity reduction are accomplished by efficient cylinder unloading.

Flexibility Completely factory assembled, piped, wired, and shipped in one piece ready for installation. Power to the single main supply power terminal block can be supplied by one field installed main supply power disconnect switch. The WHR packaged water chillers come in 25 sizes between 17 and 210 nominal tons (50 and 710 kW).

Reliability WHR chillers use Copeland DISCUS semi-hermetic compressors. These compressors are designed for Refrigerant 22. All safety and operating controls are tested and calibrated at the factory. A complete set of safety controls for each circuit is used. Safety controls include compressor crankcase heater(s), freeze protection pressurestats (manual reset), oil switches (manual reset), high pressure safety switches (manual reset), and compressor motor overload protectors. Standard operating controls include time delay relays for 20-second sequence starting of compressors, manual pumpdown switches, low pressure controls, compressor lead-lag switches (WHR-040EW-210EW) and chilled water temperature controller. An optional control circuit transformer is available, eliminating the need for a separate 115V power supply to the controls.

Serviceability Semi-hermetic, 1750 rpm induction type motors are used. The motors are refrigerant gas cooled. A finned motor housing helps dissipate motor heat. Solid-state modules in the motor terminal box respond to temperature sensors imbedded in all three motor windings to provide inherent thermal overload protection for all run and start conditions. Both suction and discharge service valves are provided to allow isolation of the compressor from the refrigerant circuit. All multiple compressor units use two independent refrigerant circuits. Dual refrigerant circuits permit shutdown and routine maintenance and service of one circuit while the second circuit maintains system operation.

Full Factory Testing Each unit is pressure tested, evacuated and charged with Refrigerant 22. With the unit at full load, individual unit performance tests and extensive quality control checks are performed to ensure each control is properly adjusted and operates correctly. Each unit is then rechecked for refrigerant leakage.

4 WHR 017EW - 210EW Product Manual WHR Design Advantages

Unit Arrangements Each unit consists of motor compressors, insulated evaporator and centralized electrical control panel containing all necessary safety and operating controls, and compressor starting controls. Units come complete with water-cooled condensers with integral subcooler circuits.

Compressors WHR chillers use Copeland DISCUS semi-hermetic compressors. These compressors are designed for Refrigerant 22. Semi-hermetic, 1750 rpm induction type motors are used. The motors are refrigerant gas cooled. Solid-state modules in the motor terminal box respond to temperature sensors imbedded in all three motor windings, providing inherent thermal overload protection for all run and start conditions. The compressor housing is constructed from close grained, high nickel content, alloy cast-iron with no bolted joint between the motor and compressor. The housing includes a cast-iron cylinder head and stator cover, and a crankcase oil sightglass. A suction strainer built into the compressor in the gas stream between the suction service valve and the motor, filters out foreign and abrasive particles. An internal relief valve relieves discharge pressure to the suction side for safety protection at high compression ratios as required by ANSI/ASHRAE 15 Safety Code. Main bearings are solid cast bronze insert type with oversized bearing area resulting in ultra-low bearing loading. The crankshaft is die-forged, high strength iron alloy with integral counterweights, statically and dynamically balanced for smooth operation. Connecting rods are lightweight aluminum with integral bearing surfaces on the crankshaft and piston ends. Pistons are close grain cast iron with oil and compression rings. Piston pins are full floating type for long life. Compressors have a force-feed lubrication system with positive oil displacement, a reversible oil pump, and an operating oil charge. The pump feeds oil through rifle-drilled passages in the crankshaft to all bearing surfaces. Magnetic plugs trap particles that enter the crankcase. The oil supply filters through a large area oil strainer. During start-up, a crankcase heater minimizes oil being diluted by refrigerant.

Factory Installed Liquid Line Components Each refrigerant circuit has a filter-drier, liquid line sightglass/moisture indicator, solenoid valve and thermal expansion valve. A manual liquid line shutoff valve, with charging connections, is supplied on all units with water-cooled condensers.

Short Circuit Protection (WHR 017EW through 030EW, WHR 095EW through 210EW) Each compressor is individually protected against short circuit and locked rotor conditions by factory installed circuit breakers. The control circuit is protected by separate fusing. WHR-040EW through 090EW can have circuit breakers factory installed as an option.

Product Manual WHR WHR 017EW - 210EW 5 Part Load Efficiencies Part load efficiencies and Integrated Part Load Values (IPLV) are calculated according to the requirements of the latest ARI Standard 590 and meet or exceed ASHRAE Efficiency Standard 90.1. Since most air conditioning systems operate at less than design full load a majority of the time, IPLV is an excellent method for comparing chillers efficiencies.

Noise All McQuay WHR chillers are available with hot gas discharge line mufflers in each refrigerant circuit to reduce the overall sound levels. Systems using remote air-cooled condensers can transmit noise through the refrigerant piping, these units are supplied with discharge line mufflers as standard. Optional insulated acoustical compressor enclosure to further reduce sound levels is also available for most units.

Unit Base Designed for easy handling , the units are mounted on a compact, rugged formed steel base. Isolator mounting holes are provided.

Electrical Control Center Shipped with all operating and safety controls and motor starting equipment factory wired, operationally tested, and ready for operation. All controls are centrally located in a hinged control center with keylocked doors. A five minute, solid-state lockout timer is provided to delay compressor restart after safety cutout or power interruption, or under irregular cooling load demands. A lead lag switch is standard on all units not incorporating the single circuit hot gas bypass option.

Evaporator The evaporator is a direct expansion, shell-and-tube type with water flowing in the baffled shell side and refrigerant flowing through the tubes. The evaporator is constructed with a carbon steel shell and seamless high efficiency copper tubes. Rolled expansion anchors the refrigerant tubes in the heavy carbon steel tube sheets. Water baffles are polypropylene to resist corrosion. Refrigerant heads are carbon steel with multi-pass baffles to ensure oil return and are removable to permit access to the tubes from either end. For water removal, 3/8" (10mm) vent and drain plugs are provided on the top and bottom of the shell. Two 1/2” (12.7mm) couplings on each water nozzle allow for easy field installation of sensor equipment. The evaporator is wrapped with 3/4” (19.1mm) thick vinyl nitrate polymer sheet insulation. The insulation has a K factor of 0.28 at 75°F (24°C). The insulation is fitted and cemented in place, then painted with a resilient vinyl base paint to resist cracking. The tube side maximum working pressure is 225 psig (1552kPa). The water side working pressure is 175 psig (1207kPa). All evaporators are designed, constructed, inspected and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code.

6 WHR 017EW - 210EW Product Manual WHR Condensers All water condensers are cleanable shell and thru-tube type with water flowing through the tubes and refrigerant in the shell. Each condenser has full circuit refrigerant charge pumpdown capacity. Independent condensers serve the unit’s dual refrigerant circuits. Each condenser is constructed with a carbon steel shell and seamless integrally finned high efficiency copper tubes. Rolled expansion anchors the tubes in the heavy carbon steel tube sheets. Water heads have drain and vent plugs, and are removable to allow tube cleaning and service. The condensers have as standard equipment a liquid shutoff valve, purge valve and 450 lb. (204kPa) spring loaded relief valve according to ANSI/ASHRAE 15 Safety Code. Refrigerant side (shell) maximum working pressure is 450 psig (3104kPa). All condensers are built and stamped according to the requirements of ASME Boiler and Pressure Vessel Code. A subcooler circuit is provided as an integral part of the condensers. The Subcooler circuit is separated from the condenser by steel baffles, causing all liquid to pass over the subcooler tubes. This ensures positive refrigerant movement in a counterflow direction to the condenser water for maximum performance.

Temperature Control

WHR 040EW through 210EW Available with three different levels of temperature control. • The standard microprocessor leaving water controller • Standard microprocessor based leaving water controller with an indicator light package • MicroTech reciprocating controller. The standard microprocessor leaving water controller is available on all units and provides precise temperature control based on leaving water temperature. The control is pre-set and calibrated. Reset of supply water temperature can be accomplished from outside air temperature, zone temperature or a signal from an EMS system. LED indicator lights display the number of stages in operation. This same controller can be provided with an indicator light package that allows the operator to see the status of all unit safeties, a power on light and compressor staging.

WHR 017EW through 030EW Two-stage units are supplied with a return water electromechanical temperature controller. Three stage units are supplied with a solid state return water temperature controller.

MicroTech Chiller Controller (optional) (WHR 040EW through 210EW) The MicroTech menu structure is separated into three distinct categories, which provide the operator or service technician with a full description of current unit status, control parameters, and alarms. Security protection prevents unauthorized changing of the setpoints and control parameters. MicroTech continuously performs self-diagnostic checks, monitoring all system temperatures, pressures and safeties, and will automatically shutdown a compressor, a refrigerant circuit or the entire unit should a fault occur. The cause of the shutdown will be retained in memory and can be easily displayed in plain English or metric units for operator review. The MicroTech chiller controller can also retain and display the time the fault occurred and the operating conditions that were present at the time of the fault. In addition to displaying alarm diagnostics, the MicroTech chiller controller also provides the operator with a warning of pre-alarm conditions.

Product Manual WHR WHR 017EW - 210EW 7 Programmable Setpoints Precise digital settings of the leaving chilled water temperature setpoint and all other control parameters. This is extremely important in the setting of safeties such as low leaving water temperature cutout, high pressure cutout, suction pressure cutout, and freeze protection.

Compressor Soft Loading Soft loading limits the number of cooling stages to prevent unnecessary electrical demand and possible overshoot of the leaving chilled water temperature setpoint.

Demand Limit Control Based on a 4-20mA DC signal, the controller will determine the maximum number of stages permitted to operate, preventing additional demand charges during high usage periods.

Automatic Circuit Lead-Lag With the keypad, the operator can manually select either refrigerant circuit for the lead position or the controller will automatically select the lead circuit based on the circuit with the fewest operating hours.

Time Clock, Daily and Holiday Start/Stop Control The operator can program daily start/stop schedules including weekends and up to fourteen separate holidays without the need of an external time clock or EMS interface. If desired, an external time clock can be used instead of the internal schedule.

Chilled Water Pump Control If an alarm shuts down the chiller, the chilled water pump will remain on, providing any remaining cooling to the loads.

Thermal Storage Thermal storage is a technique for shifting all or part of a building’s air conditioning requirements from on-peak to off-peak hours. Cooling energy is produced and stored during off-peak hours when utility rates are lower and then used during the on-peak hours. The benefits of thermal storage obtained by the building owner are attractive rate schedules and in many cases rebates from the utility company.

Partial or Full Storage Thermal storage systems can be designed to provide either partial storage or full storage of the air conditioning load. Although a partial storage system shaves the peak load, it will require chiller operation during on-peak periods. A full storage system provides enough storage to meet the building’s full on-peak cooling requirement with the chiller only operating during off-peak hours. The partial storage system achieves less of a demand reduction than full storage but the initial cost of the system is less expensive since less storage capacity is required.

8 WHR 017EW - 210EW Product Manual WHR Selection Procedure

1. Ratings may be interpolated for any chiller water temperature between 40°F and 50°F but cannot be extrapolated. 2. Chilled water quantities - Ratings are based on a 10 degree chilled water range and are applicable from a minimum of 6°F to a maximum of 16°F differential between entering and leaving chilled water temperature. 3. Condenser water quantities - Ratings are based on a 10°F rise in condenser water temperature and are applicable from 1-1/2 to 4 GPM/ton (20°F to 7.5°F rise) except as limited by pressure drop in Figure 2, Evaporator Pressure Drop WHR 040EW through 090EW. 4. Figure 1 and Figure 2 beginning on page 19, indicate evaporator and condenser water pressure drop data. Water flow rates should be maintained within these limits, which are based on minimum and maximum flow rates. The total condenser water flow should be split between condensers according to the nominal tonnage of each refrigerant circuit as shown in Table 5 through Table 7. Pressure drop capacity ratings are based on parallel water connection of condensers. 5. Ratings are based on 0.00025 fouling factor for both condenser and evaporator. For other fouling factors, multiply ratings by evaporator and condenser factors from Table 2 and Table 3. For applications using a glycol solution, see Table 1 and Table 4. Selection Procedure Note: If the Knowing the required chiller capacity in tons, the leaving (supply) water temperature and either the condenser water chilled water temperature range-delta T, or the gpm, determine the unknown quantity using the temperature rise is formula: other than 10 degrees, make GPM×− Delta T certain the condenser Tons = water inlet 24 temperature column corresponding to the Knowing the required chiller capacity (tons), the entering condenser water temperature, and either the correct leaving condenser water temperature range-delta T, or the GPM, determine the unknown quantity using the condenser water temperature is used. formula: ° (i.e., 75 F condenser THR Nominal Tons Cooling Capacity ×30 water, 20 degree rise: Condenser GPM = = use 85°F entering 500 ×−Delta T Cond.

5. From Figure 2 and Figure 3 for the WHR-070EW, pressure drops are as follows: a. Evaporator pressure drop at 165 GPM is 6.2 feet water. b. Condenser pressure drop at 210.6 GPM is 12.5 feet water.

10 WHR 017EW - 210EW Product Manual WHR Application Adjustment Factors

Ethylene And Propylene Glycol Factors WHR units are designed to operate with a leaving chilled fluid temperature range of 21°F (-6.1°C) to 50°F (10°C). Leaving chilled fluid temperatures below 40°F (4.6°C) result in suction temperatures at or below the freezing point of water and a glycol solution is required. The use of glycol in the evaporator will reduce the performance of the unit. The reduction in performance depends upon the glycol concentration. This should be taken into consideration during initial system design. McQuay encourages a minimum concentration of 25% be provided on all glycol applications. Glycol concentrations below 25% are to diluted for long-term corrosion protection of ferrous metals.

Note: Glycol in the condenser will have a negligible effect on performance because glycol at higher temperatures will perform with characteristics similar to water. Evaporator and Condenser Temperature Drop Factors Performance tables are based on a 10°F (5°C) temperature difference through the evaporator and condenser. A temperature difference other than 10°F (5°C) will result in unit performance being different from what is shown. Adjustment factors for applications having temperature drops between 6°F and 16°F (3.3°C to 8.9°C) can be found in Table 2 and Table 3. Temperature drops outside of this range may adversely affect the control system’s ability to maintain acceptable control, and are not recommended. Fouling Factor Performance tables are based on water with a fouling factor of 0.00025 ft2 ××° hr F / BTU (0.044 M2°C/kW) according to ARI 590. As fouling is increased, performance decreases. For performance with a fouling factor other than 0.00025 (0.044), see Table 2 and Table 3. To ensure optimum unit operation, proper water treatment must be maintained. Scaling and dirt in a system will vary significantly depending on local water conditions. Water treatment should be based on characteristics of the area’s water. Improper or untreated water may lead to scale build up, erosion and corrosion in both the condenser and evaporator. McQuay will not accept responsibility for poorly or improperly treated water.

44 WHR 017EW - 210EW Product Manual WHR Application Data

Location and Space Requirements Unit is designed for indoor application and must be located in a space where the temperature is 40°F (4.4°C) or above. Provide clearance of 2 to 3 ft. (609 to 914mm) on each side and ends for piping and to help when servicing unit. Provide clearance at either end of the unit to permit cleaning of condenser tubes or for removal of tubes from condenser or cooler (see dimensional data). If a door or window is provided at one end of the unit, the tubes may be replaced through the opening provided.

Foundation Mount the unit on a level concrete foundation. Floors must be strong enough to support the unit weight. If necessary, use structural supports to transfer the weight of the unit to the nearest beams.

Vibration Isolation Vibration mounts are recommended for upper floor installations or where compressor noises might be objectionable (next to occupied spaces such as offices, meeting rooms, etc.). Vibration eliminators may be used for water piping connected to the unit to avoid transmission of water or pump noise into occupied spaces.

Typical Chilled Water Piping Flush the system water piping thoroughly before making connections to the unit evaporator. Install a 40 mesh strainer in the return water line before the inlet to the chiller. Design the water piping so the chilled water circulating pump discharges into the evaporator inlet. Connect return water line to evaporator inlet connection. Connect supply water line to evaporator outlet connection. Install a flow switch in the horizontal piping of the supply (evaporator outlet) water line. Provide drain connections at low points in the system to permit complete drainage of the system. Air vents should be located at the high points in the system to purge air out of the system. A vent connection on top of the evaporator vessel allows air to be purged. Purge air from the water system before unit start-up to ensure adequate flow through the evaporator. Install pressure gauges in the inlet and outlet water lines to the evaporator. Measure pressure drop through the evaporator to calculate proper flow. Vibration eliminators are recommended in both the supply and return water lines. Chilled water piping should be insulated to reduce heat loss and prevent condensation. Chillers not running in the winter should have their water systems thoroughly drained to protect against freezing. If the chiller operates year round, or if the system is not drained for the winter. Protect the outdoor chilled water piping against freezing. Wrap the lines with a heater cable and add proper amount of glycol to the system to further protect the system.

Condenser Water Be certain the condenser water enters the bottom connection of the condenser. The condenser water will exit the condenser from the top connection. Head pressure control must be provided. Fan cycling and modulating discharge dampers on the cooling towers or a three-way bypass valve around the tower is often used. Consult the tower manufacturer for information on specific applications. If city or well water is used for condensing, a two-way pressure actuated water regulating valve should be installed in the outlet piping of each condenser. The condenser purge valve provides a convenient pressure tap for the regulating valve. The valve can modulate in response to head pressure. When the compressor shuts down, this valve closes, preventing water from being siphoned out of the condenser.

Series or Parallel Operation Consider system pressure drop when designing the water piping. Parallel piped systems have half of the total system flow going through the evaporator of each chiller, reducing the individual unit and total system pressure drop. Series piped evaporators require that the total system water flows through both evaporators. Not only is the pressure drop through each evaporator increased but the pressure drops must be added together to obtain the total evaporator pressure drop. Series piped evaporators normally require larger circulating pumps for the chilled water system.

Electrical Hookup Every WHR chiller requires field installation of the main supply power, 115V hookup of the control circuit, system timeclock on-off switch, flow switch, and COPS pump starter relay. An optional “control circuit transformer” installed at the factory eliminates the need for field hookup of a separate 115V supply to the control circuit. See Figure 6 for field electrical hookups. The diagram shown represent all WHR units; however, individual terminal numbers may vary between unit sizes. Each unit is provided with its specific wiring diagram in the control panel. All wiring must be done according to local and national codes.

Main Power Supply Disconnect Switch Every WHR unit uses a single factory installed main power supply terminal block. The main power supply terminal block will accept single or parallel power supply wiring. A factory installed non-fused disconnect switch is available as an option on WHR 040EW and above with single point power supply. The disconnect is properly sized for the model and voltage supplied.

46 WHR 017EW - 210EW Product Manual WHR Control Circuit Terminals are provided in the unit control center (terminals 1 and NB, typical field wiring diagram) for field hook-up of the control circuit to a 115V power supply. An optional control circuit transformer installed at the factory eliminates the requirement for a separate power supply to the control circuit. Terminals are also provided for field connection of the chilled water flow switch, unit time clock, ambient thermostat and/or remote on/off switch.

Compressor Time Lockout A fixed 5-minute solid-state lockout time delays compressor restart after safety cutout or power interruption, or under irregular cooling load demands.

Interlock Wiring The condenser water pump should be interlocked to cycle with the compressor(s). This will prevent the refrigerant pressure from being overly depressed during the off cycle and allows the energy savings of pump shutdown. Interlock terminals are provided in the unit control panel.

Design Limitations 1. Maximum allowable condenser water pressure is 250 psig (1724 kPa) (WHR 017EW through 210EW). 2. Maximum allowable evaporator water pressure is 175 psig (1207 kPa) (WHR 017EW through 210EW) 3. Maximum design saturated discharge temperature (SDT) is 140°F (60°C). SDT=Condensing temperature + discharge line loss. 4. Maximum allowable water temperature to evaporator in a non-operating cycling is 100°F (37.8°C). Maximum entering water temperature for operating cycle is 90°F (32.2°C) (during system changeover from heating to cooling cycle). 5. Minimum design leaving water temperature from the evaporator without freeze protection is 42°F (6°C). 6. Contact your McQuay representative for operation with tower condenser water entering the chiller below 70°F (21.1°C).

Product Manual WHR WHR 017EW - 210EW 47 Optional Features

Control Circuit Transformer For applications where a separate 115 volt power source is not available. The transformer is factory installed and wired between the line voltage power terminal block and the 115 volt control circuit.

For MicroTech network systems, the PC gives the operator access to all unit and auxiliary controllers in the network. Specific controller or global data can be displayed as desired. All keypad status information and control capability is available at the PC in a full-screen format. Many additional unit control parameters, which are not available at the unit controller’s keypad, are also available. Monitor software provides the following features: • High resolution, unit-specific graphic representations • One-touch function keys • Multiple unit display screen • Automatic screen refresher • Help text • Dial-up communications • Alarm monitoring and management • Scheduling • Trend logging • Downloading capability • Multi-level password protection • Controller Diagnostics

Open Protocol Open Protocol provides an interface between MicroTech unit controllers and the building automation system of one of several participating manufacturer. A protocol is a set of rules governing data exchange between microprocessors, permitting communications between unlike controllers. Because there is no universally standard protocol, McQuay has “opened” MicroTech protocol to a growing number of building automation system partners. As a result, building designers, owners and operators can obtain the advantages of McQuay equipment, and the control versatility MicroTech has to offer.

Product Manual WHR WHR 017EW - 210EW 49 Water Flow Switch A water flow safety switch in the chilled water piping prevents evaporator freeze-up under low or no flow conditions. Terminals are provided in the unit control center for field hookup of the water flow safety switch.

Discharge Line Mufflers Discharge line mufflers are available as an option on all units and are standard on units 185 tons and above. Discharge line mufflers are recommended on any water cooled unit with entering condenser water temperature in excess of 100°F (37.8°C) or when optional acoustical enclosure is ordered.

Chilled Water Reset (WHR 040EW through 210EW) In applications when outside temperature has a major effect on the load of the building outdoor air reset can be provided to increase the system efficiency by resetting the supply water temperature upward as the outside temperature drops.
