Abstract: The present invention relates to a heat management system comprising: a refrigerant circulation line including a compressor, a compressor for compressing and discharging a refrigerant, a water cooling-type condenser for condensing the compressed refrigerant using cooling water, a first expansion valve for expanding the condensed refrigerant, and a water cooling-type evaporator for evaporating the expanded refrigerant using cooling water; a heating line including a heater core which circulates the cooling water that has exchanged heat in the water cooling-type condenser, and thereby generates conditioned air for heating; a cooling line (305) including a cabin cooler (520) which circulates the cooling water that has exchanged heat in the water cooling-type evaporator (242), and thereby generates conditioned air for cooling; and a cooling line (302) which is connected to or disconnected from the heating line according to the cooling/heating mode, and cools a battery (350) and an electrical component (460). The heat management system enables efficient heat management of an electrical component and a battery in a vehicle, in addition to the cooling and heating of the vehicle, and can improve heat pump performance and system efficiency.

Abstract: A heat management system including a refrigerant circulation line including a compressor, a water-cooling condenser, an air-cooling condenser, a first expansion valve, an evaporator, a refrigerant heat exchanger, and a gas/liquid separator that discharges only a liquid refrigerant, and cooling an indoor place by circulating a refrigerant; a heating line for heating the indoor place by circulating, through the water-cooling condenser, cooling water that exchanges heat with the refrigerant; and a cooling line for cooling a battery and an electrical component by circulating air or cooling water that exchanges heat with the refrigerant. Therefore, the present invention can not only cool and heat a vehicle but also efficiently manage heat for an electrical component and a battery in a vehicle, and can reduce the number of constituent components for heating and cooling.
