VEHICLE THERMAL MANAGEMENT SYSTEM AND METHOD FOR CONTROLLING THE SAME

A vehicle thermal management system, may include a heating, ventilation, and air conditioning (HVAC) subsystem including an HVAC casing in which a heater core and an evaporator are received; and a cooling subsystem including a coolant loop through which a coolant circulates, wherein the heater core is located on the downstream side of the evaporator in an air flow direction, and the coolant loop is thermally connected to the heater core. The HVAC subsystem includes: an air mixing chamber located on the downstream side of the heater core within the HVAC casing; a discharge pipe fluidically communicating with the air mixing chamber, and being opened to the outside of a passenger compartment; and a flap configured for selectively opening and closing the discharge pipe.
