Condenser for vehicle and air conditioning system for vehicle

Abstract

A condenser may include a main radiating portion including a plurality that is formed by laminating a plurality of plates, a receiver drier portion integrally formed at one side end of the main radiating portion, a supercooling radiator that is integrally formed at a lower portion of the main radiating portion, and an accumulator portion integrally formed with the main radiating portion and the other end portion of the supercooling radiator. An air conditioning system may include an expansion valve, an evaporator, and an electrically driven compressor, a water cooler condenser, and a heat exchanger, wherein a liquid state refrigerant of a middle temperature and high pressure passing the water cooler condenser exchanges heat with a low temperature / pressure refrigerant passing the evaporator in the heat exchanger.

Problems solved by technology

Therefore, the cost and weight will increase, and the connection between the receiver-dryer and the condenser will be complicated

[0012] When the coolant is cooled by water in a conventional air conditioning system, the coolant cooled by the outside air exchanges heat with the coolant of the condenser, thereby increasing the temperature of the coolant at the outlet of the condenser, so there is a problem of increased power consumption

[0013] Also, when the secondary cooling area is increased to improve the cooling performance in the conventional air conditioning system by increasing the heat exchange amount of the coolant, the superheating process is increased above the base temperature, and the internal temperature of the compressor is increased, so the electric compressor may Damaged by the heat and at the same time there is a problem of unvaporized liquid refrigerant flowing in it and the compressor is damaged

[0014] Also, when the evaporator enthalpy is increased by increasing the secondary cooling area in the conventional air conditioning system, the cooling performance is improved, but the suction amount of the compressor is increased due to the increase in the specific volume according to the increase in the inlet / outlet coolant temperature of the compressor And lower, the evaporation capacity of the evaporator is reduced, so there is a limitation in improving its cooling performance
