Abstract
The expanded flow through a heat exchanger type economizer is controlled by an electronic expansion valve and is supplied to the motor of a motor compressor to cool the motor. The electronic expansion valve is controlled by a microprocessor responsive to the temperature of the motor winding sensed by a thermistor.
