    FORM 150.26-EG1 (116) Equipment Overview YORK YCWL Water-Cooled chillers provide chilled water for all air conditioning applica- tions that use central station air handling or terminal units. They are completely self- contained and are designed for indoor (new or retrofit) installation. Each unit includes hermetic scroll compressors, a liquid evaporator, water cooled condenser, and a user- friendly, Microcomputer Control Center mounted on a rugged steel base.
  • Page 6 AHRI CERTIFICATION PROGRAM YORK YCWL chillers have been tested and certified by Air-Conditioning, Heating and Re- frigeration Institute (AHRI) in accordance with the latest edition of AHRI Standard 550/590 (I-P).

    FORM 150.26-EG1 (116) Refrigerant Flow Diagram Low-pressure liquid refrigerant enters the evaporator tubes and is evaporated and super- heated by the heat energy absorbed from the chilled liquid passing through the evaporator shell. Low-pressure vapor enters the compressor where pressure and superheat are in- creased.

  • Page 22: Application Data

    FORM 150.26-EG1 (116) Application Data UNIT LOCATION Chillers are designed for indoor installation. Units should be located away from noise-criti- cal areas. Service clearance must be allowed and include space for remov ing condenser tubes. A doorway or window can sometimes provide space for tube removal. Units should be installed indoors where they are not exposed to rain or water splash.
  • Page 23 All field wiring must comply with the National Electric Code and all applicable local codes. YORK liquid chiller units are factory wired for optimum reliability. Therefore the unit con- trols must not be modified without ex pressed written consent by Johnson Controls. The use of a simple switch or timer from a remote point is permitted;...
