"Variable Speed Compressor"
Abstract: A large tonnage water chiller 60 is disclosed that includes a drive motor 11a connected to a proximal drive shaft 18, 18a, 18b. The proximal drive shaft 18 is connected to a continuous variable transmission (CVT) 15, 15a, 15b. The CVT 15, 15a, 15b is connected to an output drive shaft 19, 19a, 19b. The output drive shaft 19, 19a, 19b is connected to an impeller 33 disposed within a compressor 10a that forms an evaporative refrigerant cycle with an evaporator 53 and condenser 52. A controller 50 controls the operation of the CVT 15, 15a, 15b based on the leaving chilled water temperature (54) in the evaporator 52 while maintaining operation of the drive motor 11a at a constant speed.
