  • Page 3: Introduction

    Introduction McQuay International offers a complete line of water-cooled chillers from 17 to 2500 tons (60 to 8800 kW) utilizing reciprocating and centrifugal compressors. The WHR packaged reciprocating compressor chillers are a product of the McQuay commitment to offer energy efficient equipment design. A design approach carefully combining high quality compressors, efficient shell-and-tube heat exchangers, and state-of- the-art controls into a unit of uncompromised operating efficiency and reliability.
  • Page 4: Features And Benefits

    Optional steps of capacity reduction are accomplished by the most efficient method of cylinder unloading in the industry today. To McQuay, operating economy means more than just energy efficiency. The WHR chillers reduce operating costs not only through energy efficiency, but by offering high unit reliability, easy serviceability, full factory testing and the backing of a factory trained sales, service and parts organization.
  • Page 5 Serviceability Semi-hermetic, 1750 rpm induction type motors are employed. 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.
  • Page 6: Design Advantages

    Design Advantages Unit Arrangements The McQuay water chillers are completely factory assembled, piped, wired and shipped in one piece, ready for field connection of refrigerant (EA models) and water piping. Each unit consists of motor compressors, insulated DX cooler and centralized electrical control panel containing all necessary safety and operating controls, and compressor starting controls.
  • Page 7 IPLV is an excellent method for comparing chillers' efficiencies. Noise All McQuay WHR chillers are equipped with hot gas discharge line mufflers in each refrigerant circuit to reduce the overall sound levels. An optional insulated acoustical compressor enclosure to further reduce sound levels is also available for most units.
  • Page 8 Air-Cooled Condensers The WHR-EA chillers are designed for use with properly sized and configured remote air-cooled or evaporative condensers. The McQuay AC/AQ line of air-cooled condensers are designed for use with these chillers. The AC/AQ condensers are available with single or double row vertical discharge fans and are fully described and rated in Product Manual PM ACAQ.
  • Page 9: Temperature Control

    Temperature Control The McQuay WHR-040EW through 210EW water chillers are available with any one of three different temperature controls to satisfy your requirements: 1) the standard microprocessor leaving water controller, 1a) the same controller but with an indicator light package, and 2) the MicroTech Controller.

  • Page 11 Operator-friendly The 12-key, touch-sensitive, membrane keypad and 32-character display makes the MicroTech system especially user-friendly. Inch-pound or SI units are optionally available. 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.
  • Page 12: Optional Network Master Panel

    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.

    (BAS). A protocol is a set of rules governing data exchange between microprocessors, thereby permitting communications between unlike controllers. As a result, building designers, owners and operators can obtain the advantages of McQuay equipment, and the control versatility MicroTech has to offer. A low cost site license covering any and all McQuay product is required.
  • Page 14: Selection Procedure

    Selection Procedure EW Water-Cooled, R-22 Ratings are based and certified in accordance with ARI Standard 550/590-98. Ratings in Table 5 through Table 10 may be interpolated for any chiller water temperature between 40°F and 50°F (4.4°C and 10.0°C) but cannot be extrapolated. Chilled water quantities - Ratings are based on a 10 degree F (5.6 degree C) chilled water range (2.4 gpm/ton) and can be used for a delta-T range of 6 to 16 degrees F (3.3 to 8.8 degrees C) by adjustments from Table 3.
  • Page 15: Ew Water-Cooled, R-134A

    The performance of the WHR chillers is listed by LWT (leaving chilled water temperature) and by Condensing Temperature. Tons, Power, and THR (Total Heat Rejection) are given. This data can then be used to select any condenser from its own capacity data. For a McQuay AC/AQ air-cooled condenser, use product manual PM ACAQ.
  • Page 16 Progressing from a) to c) above will require smaller condensers, offset by larger, more expensive chillers and lessening efficiency. 2) A condenser can be selected with the above information. For this example, a McQuay Model ACAQ air-cooled condenser will be selected using selection procedures and data contained in Product Manual PM ACAQ.
  • Page 17: Ea Remote Condenser, R-134A

    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 too diluted for long-term corrosion protection of ferrous metals and corrosion inhibitors may need to be recalculated.
  • Page 18: Evaporator And Condenser Delta-T Factors

    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.

  • Page 65: Application Data

    Application Data Location and Space Requirements The units are 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 914 mm) on each side and ends for piping and to help when servicing unit.
  • Page 66 Figure 14, Typical chilled water piping Condenser Water (EW Units) 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 if the entering condenser water can fall below 60°F.
  • Page 67 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.
  • Page 68 Minimum design leaving water temperature from the evaporator without freeze protection is 42°F (6°C). Contact your McQuay representative for operation with tower condenser water entering the chiller below 70°F (21.1°C). Compressor unloading is not allowed with leaving chilled fluid temperatures 35°F or less.
