Abstract
Cooling systems and methods for controlling the temperature of motors of gas compression systems of chillers are disclosed. Certain systems utilize a centrifugal, two stage compressor equipped with a motor between the stages. The cooling system provides a low velocity refrigerant spray on at least one or both ends of the motor without requiring additional pumping energy from the motor to deliver the refrigerant spray.
