본 고안은 자동차, 특히 전기자동차용 공조장치에 대한 제안 기술에 관한 것으로써 새롭게 제안되는 구성의 냉난방장치에 관한 것이다.The present invention relates to a proposed technology for an air conditioner for an automobile, in particular an electric vehicle, and relates to a cooling and heating device having a newly proposed configuration.

일반적으로 제안되는 전기자동차에서 채택되는 히트펌프사이클을 이용한 전기자동차의 공조장치에 있어서, 난방모우드시에 증발 실외기에서 차가운 외부공기와의 열교환을 위하여 증발온도를 외부공기의 온도보다 약 10도섭씨 이상 낮추어 설정하여야 한다. 이런 경우에 사이클의 성적계수가 낮아져 열효율이 떨어지고 증발기에서 결빙이 생길 경우 시스템 가동이 어렵게 된다는 문제점이 발생한다.In the air-conditioning apparatus of an electric vehicle using a heat pump cycle generally adopted in the proposed electric vehicle, the evaporation temperature is about 10 degrees Celsius or more than the temperature of the outside air for heat exchange with the cold outside air in the evaporation outdoor unit during the heating mode. It should be set lower. In this case, there is a problem that the system's operation becomes difficult if the performance coefficient of the cycle is lowered and the thermal efficiency decreases and freezing occurs in the evaporator.

이상과 같은 문제점을 감안하여 본 고안의 전기자동차용 공조장치에서는 낸방용의 증발기와 난방용의 증발기를 구분함으로써 상기의 문제점을 해결하는 것을 목적으로 한다.In view of the above problems, an electric vehicle air conditioner of the present invention aims to solve the above problems by distinguishing an evaporator for heating and an evaporator for heating.

상기의 목적을 달성하기 위한 본 고안의 전기자동차용 공조장치의 구성 및 작용을 부수된 도면과 함께 더욱 상세히 설명한다.The construction and operation of the air conditioner for an electric vehicle of the present invention for achieving the above object will be described in more detail with accompanying drawings.

제1도는 일반적인 자동차용 히트펌프사이클의 구성도, 제2도는 본 고안의 전기자동차용 공조장치의 구성도, 제3도는 실내기등의 각 부재를 차량에 부착하는 경우의 위치를 도시하는 구성도로서 함께 설명한다.FIG. 1 is a block diagram of a general automotive heat pump cycle, FIG. 2 is a block diagram of an electric vehicle air conditioner of the present invention, and FIG. 3 is a block diagram showing the position where each member such as an indoor unit is attached to a vehicle. Explain together.

제1도의 일반적인 히트펌프사이클에서는 통상적으로는 압축기(1)와 냉매 유체연결되는 사방변(2), 실내기(3), 실외기(5), 팽창변(4), 냉매배관(6)으로 구성되어 있다. (→)는 난방모우드시의 유체흐름을 도시하고(‥‥→)은 냉방모우드의 유체흐름을 도시한다.In the general heat pump cycle of FIG. 1, the compressor is generally composed of four sides (2), an indoor unit (3), an outdoor unit (5), an expansion valve (4), and a refrigerant pipe (6) connected to a refrigerant fluid. . (→) shows the fluid flow in the heating mode (...) and (→) shows the fluid flow in the cooling mode.

본 고안의 자동차용 히트펌프사이클에서는 제2도에 도시된 바와 같이 실외기를 응축실외기(15)와 증발실외기(25)의 2개의 실외기로 구성하고, 증발실외기(25)는 온수배관(11)등의 유체배관수단으로써 밧데리실(10) 주변부를 펌프(13)로서 유체 순환하는 방열기(12)와 인접대향하여 있게 함으로써 밧데리실(10)에서 발생하는 통상적인 폐열을 이용하여 온수순환하여 방열기(12)로 부터 잉여 폐열이 전달되어 방출되도록 구성한다.In the heat pump cycle for an automobile of the present invention, as shown in FIG. 2, the outdoor unit includes two outdoor units, a condensation outdoor unit 15 and an evaporation outdoor unit 25, and the evaporation outdoor unit 25 includes a hot water pipe 11, and the like. By circulating the battery compartment 10 around the battery chamber 10 with the radiator 12 which circulates fluid as the pump 13 as a fluid piping means, the hot water is circulated using the normal waste heat generated in the battery chamber 10 to radiate the heat radiator 12. Excess waste heat is transferred from) and released.

상기 실외기(15, 25)와 방열기(12)의 열함수는 실험적으로 주행환경과 차량의 연비등을 고려하여 결정될 수 있다.The heat functions of the outdoor units 15 and 25 and the radiator 12 may be experimentally determined in consideration of the driving environment and fuel economy of the vehicle.

제3도에서는 방열기(12)와 증발실외기(25)의 위치를 차량 후미쪽에 설치하여 실내공기의 배출폐열을 함께 이용할 수 있음을 도시한다.3 shows that the location of the radiator 12 and the evaporator outdoor unit 25 can be installed at the rear of the vehicle to use the waste heat of the indoor air together.

상기와 같은 밧데리실의 폐열을 이용하는 듀얼 실외기의 구성으로써 난방시에 증발기로의 공기통로 전방에 자동차의 밧데리에서 발생하는 폐열을 회수함으로써 발산되는 방열기를 이용함으로써 폐열을 운전조건에 적합하게 설정하여 결빙을 방지할 수 있다.As a dual outdoor unit using waste heat of the battery chamber as described above, the heat is radiated by recovering the waste heat generated from the battery of the car in front of the air passage to the evaporator during heating to set the waste heat to suit the operating conditions and freeze. Can be prevented.
