    Abstract: A secondary loop HVAC system including an evaporator, a condenser, an expansion valve, and a compressor. A refrigerant loop is in fluid communication with each of the evaporator, the condenser, and the expansion valve. An HVAC case includes a first heat exchanger and a second heat exchanger. A first coolant loop is in fluid communication with the first heat exchanger, the second heat exchanger, and either the evaporator or the condenser. A valve system is configured to control flow of the coolant through the first coolant loop. In a maximum hot heating mode, the valve system is configured to direct the coolant through the condenser, the first heat exchanger, and the second heat exchanger. In a maximum cold cooling mode, the valve system is configured to direct the coolant through the evaporator, the first heat exchanger, and the second heat exchanger.

    Abstract: A temperature control system for an engine. The system includes a thermal storage expansion tank defining a thermally insulated interior volume for storing engine coolant. The system further includes a pump that pumps engine coolant that has exited the thermal storage expansion tank back into the thermally insulated interior volume of the thermal storage expansion tank and forces air out of the thermal storage expansion tank to store coolant in the thermally insulated interior volume when the engine is off.
