AIR CONDITIONER FOR AN ELECTRIC VEHICLE CAPABLE OF REDUCING THE POWER CONSUMPTION OF A COMPRESSOR

摘要

PURPOSE: An air conditioner for an electric vehicle is provided to improve heat exchange efficiency by increasing the amount of evaporation heat using heat transferred from a heat source. ;CONSTITUTION: An air conditioner for an electric vehicle comprises a compressor(10), indoor and outdoor heat exchangers(20,30), an expansion valve(40), an auxiliary heat exchanger(50), and a switching valve(70). The compressor compresses and transmits refrigerants. The indoor and outdoor heat exchangers are installed inside and outside an electric vehicle. The transmitted refrigerants are moved in the indoor and outdoor heat exchangers. The expansion valve expands the refrigerants. The auxiliary heat exchanger receives heat from a heat source of the electric vehicle. The switching valve selectively connects refrigerant pipes connected to the indoor and outdoor heat exchangers and the compressor and controls the flow of the refrigerants.;COPYRIGHT KIPO 2011
