Evaporator feed system with flash cooled motor
摘要:
Gaseous refrigerant is supplied from a flash tank economizer to cool the motor of a hermetic or semi-hermetic compressor when there is a sufficient flow available. When the flow becomes too small, liquid refrigerant is supplied to the shell of the compressor for cooling the motor.
