Abstract
An HVAC system including an evaporator, a condenser, an expansion valve, and a compressor. An HVAC case includes a first heat exchanger having a first height, a second heat exchanger having a second height that is greater than the first height, and an air mix door movable to direct airflow from the second heat exchanger to the first heat exchanger or around the first heat exchanger. In a maximum hot mode, a valve system directs the coolant through the condenser, the first heat exchanger, and the second heat exchanger, and the air mix door directs airflow from the second heat exchanger to the first heat exchanger. In a maximum cold mode, the valve system directs the coolant through the evaporator, the first heat exchanger, and the second heat exchanger.
