    Ratings AHRI CERTIFICATION PROGRAM YORK YK chillers have been tested and certified by Air-Conditioning, Heating and Refrigeration Institute (AHRI) in accordance with the latest edition of AHRI Standard 550/590 (I-P). Under this Certification Program, chillers are regularly tested in strict compliance with this Standard.
  • Page 9 FORM 160.84-EG1 (617) Ratings (Cont'd) The chiller is engineered for maximum efficiency at both design and part-load operation by taking advantage of the colder cooling tower water temperatures which naturally occur during the winter months. Appreciable power savings are realized from these reduced heads. The minimum entering condenser water temperature for other full and part-load conditions is provided by the following equation: where:...

    NOTE: Please refer to the OptiView Control Center Operator's Manual for a complete description of features and functionality. The YORK OptiView Control Center is a factory mounted, wired and tested microproces- sor based control system for HFC-134a centrifugal chillers. For the YMC², it controls the leaving chilled liquid temperature and limits the motor current via control of the Variable Geometry Diffuser (VGD) and Variable Speed Drive (VSD).

  • Page 25 FORM 160.84-EG1 (617) OptiSpeed Variable-Speed Drive (Cont'd) The OptiSpeed output sine filter network is composed of inductors and capacitors. The job of the output filter network is to eliminate voltage harmonics from the inverter’s output, and provide a high-quality, almost-sinusoidal voltage to the motor. This completely eliminates all issues related to premature motor insulation failures due to high voltage peaks gen- erated by the inverter, and it additionally allows the motor to run cooler, thus increasing system reliability.
