A system and method for providing cool air to a passenger compartment of a hybrid vehicle in an engine off mode is disclosed. This may include operating a HVAC system to provide cold refrigerant flowing through an evaporator while an engine is operating, and forcing air through the evaporator to cool the air. A first portion of the cooled air from the evaporator is directed through a heater core and a second portion around the heater core, and an electric water pump is activated to pump coolant from a thermal storage tank, through the heater core and back to the thermal storage tank to cool the coolant. When the engine operation is ceased, the air flow is directed through the heater core, and the coolant is pumped from the thermal storage tank, through the heater core and back to the thermal storage tank to cool the air. |
