Abstract
Apparatus and method are disclosed for providing a relatively constant temperature level flow of discharge air from a reverse cycle air conditioning system. Air temperature of the air being discharged from the indoor heat exchanger of the refrigeration circuit is measured and used to control indoor fan speed to maintain the supply air temperature to the enclosure at a relatively constant temperature level. A secondary zone may be provided for receiving conditioned air from the indoor heat exchanger. A damper regulated in response to the leaving air temperature from the indoor heat exchanger is used to control the volume flow rate to the secondary zone such that as the indoor fan speed is decreased the damper decreases the volume flow rate to the secondary zone while maintaining a constant volume flow rate to the primary zone. An outdoor thermostat is provided for operating the indoor fan at normal speeds when the ambient temperature is within a predetermined range.
