Abstract
A vehicle includes a refrigerant system having an intermediary heat exchanger, an exterior heat exchanger, and an expansion device disposed therebetween. The vehicle also includes a coolant circuit having a pump configured to circulate coolant through the intermediary heat exchanger and an engine. A controller is programmed to, in response to air conditioning being requested and the coolant temperature exceeding a threshold temperature, open the expansion device and de-energize the pump to condense refrigerant in the exterior heat exchanger.
