ABSTRACT:
A combined heating and air conditioning unit has a condenser for cooling compressed working fluid and an evaporator for expanding the working fluid and to cool it. A centrifugal blower pulls air through the condenser into one side of the blower and pulls cool air through the evaporator into the other side of the blower. A divider in the center of the blower prevents the cool air from the evaporator and warm air from the condenser from mixing. At the output of the blower, a valve is provided at the output and connected to the delivery duct so that warm air from one side of the blower or cold air from the other is delivered to the duct, and the air not delivered to the duct is exhausted to the atmosphere. The valve may also allow some mixing of the warm and cold air.
