Patent attributes
A heating, ventilating, and air conditioning (HVAC) system of a vehicle may include a battery cooling line to circulate a first coolant through a first radiator, a high voltage battery core, and a first valve; an electronic component cooling line to circulate a second coolant through a second radiator, an electronic component core, and a second valve; a branch line having a first end portion branched from the first valve and a second end portion connected to an upstream point of the high voltage battery core; an auxiliary line having a first end portion branched from the second valve and a second end portion connected to an upstream point of the electronic component core; and a controller performing heat transfer in the main heat exchanger by controlling the first valve and the second valve when a temperature of the high voltage battery core is required to be increased.
