ABSTRACT:
In a heat pump system operating in the heat cycle mode, a sensor is provided for sensing either the pressure or temperature of a refrigerant. A speed controller receives an output of the sensor so that the speed (including cycle rate) of an evaporator fan is controlled, resulting in control of the pressure or temperature of the refrigerant. The temperature or pressure of the refrigerant is controlled for a heat pump system comprising one refrigeration circuit and more than one refrigeration circuit. A separate speed control is provided for a fixed speed motor, a sleeve bearing fan motor, and a variable speed ball bearing fan motor.
