Abstract:
A vehicle includes a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment. The HVAC system includes a refrigerant loop and a coolant loop, and an auxiliary heating, ventilation and air conditioning (HVAC) system. The auxiliary HVAC includes an expansion device coupled to the refrigerant loop for controlling a flow of refrigerant to a first heat exchanger, and a second heat exchanger coupled to an auxiliary coolant loop used to regulate a temperature of the component. The auxiliary HVAC further includes a blower for creating an air flow through the first heat exchanger, a first blend door for directing the air flow through the second heat exchanger and/or an outlet, a second blend door for directing the air flow through the outlet and/or a recirculation duct, and a third blend door for controlling the air flow through the recirculation duct.
