Description
본 발명은 2개의 증발기를 구비한 차량용 에어컨 시스템에 있어서, 서로 직경이 다른 2개의 배관이 결합된 가스, 액체 열교환기 겸용 배관을 구비하고 상기 배관을 통하여 응축기에서 멀리 이격되어 배치되는 증발기 유닛의 팽창장치 입구에서 냉매의 과냉도를 증가시키도록 하므로서 증발기의 냉방능력을 향상시키며 액체배관과 가스배관을 일체형으로 형성하여 냉매배관의 설치를 용이하게 할 수 있도록 한 이중 증발기 구조를 가진 차량용 에어컨장치에 관한 것이다.The present invention relates to a vehicle air conditioner system having two evaporators, the expansion of the evaporator unit having a gas, liquid heat exchanger combined pipe combined with two pipes of different diameters and spaced apart from the condenser through the pipe. To improve the cooling capacity of the evaporator by increasing the supercooling of the refrigerant at the inlet of the device, and to provide a vehicle air conditioner having a double evaporator structure to facilitate the installation of the refrigerant pipe by forming the liquid and gas piping integrally will be.
종래 일반적인 차량의 내부에는 냉방을 위하여 냉방장치인 에어컨 시스템을 구비하고 있으며, 이 에어컨 시스템은 증발기와 응축기 및 압축기로 구성되어 있고 상기 응축기는 외부로 열을 방출하도록 하고, 압축기에 의하여 압축된 냉매가 증발기 유닛내로 흡인된 공기의 열을 흡수하면서 증발작용을 하여 공기를 저온화시키고 이 저온화된 공기를 블로어를 이용하여 차량의 실내로 공급하도록 구성되어 있었다.Conventionally, the inside of a vehicle is provided with an air conditioning system that is a cooling device for cooling, the air conditioning system is composed of an evaporator, a condenser and a compressor, the condenser discharges heat to the outside, the refrigerant compressed by the compressor It was configured to evaporate while absorbing the heat of the air drawn into the evaporator unit to lower the air and supply the lowered air to the interior of the vehicle using a blower.
또한, 상기 냉방효율을 향상시키기 위하여 상기 냉매회로에 2개의 증발기를 구비한 것이 도 1에서와 같이 안출된 바 있었으며, 이는 하나의 응축기(2)와 압축기(1)를 구비하고 1개의 리시버 드라이어(3)를 공유하면서 2개의 팽창장치(601)(701)와 2개의 증발기(401)(501)를 각각 연결시켜 냉매회로를 구성하도록 되어 있었고, 이들 증발기(401)(501)는 상기 응축기(2)에서 대체로 멀리 이격된 위치에 설치되도록 구성되어 있었다.In addition, in order to improve the cooling efficiency, the refrigerant circuit has been provided with two evaporators as shown in FIG. 1, which has one condenser 2 and a compressor 1, and one receiver dryer ( 3, the two expansion devices 601, 701 and two evaporators 401, 501 are connected to each other to form a refrigerant circuit, and these evaporators 401, 501 are the condenser 2 It was configured to be installed in a location that is generally far away from the.
그러나, 상기와 같은 종래의 것은 상기 증발기가 응축기와 멀리 이격된 상태로 설치되어 있기 때문에 이들 사이를 연결하는 냉매용 배관의 길이가 길어지게 되고 이 길어진 배관에 의하여 냉매의 압력강하량이 크게 되는 폐단이 있었으며, 이에 따라 증발기 유닛의 팽창장치 입구에서의 냉매압력이 낮아지게 되고 냉매의 온도와 냉매의 압력에 해당하는 응축 포화온도의 차이(과냉도)가 줄어들게 되므로 증발잠열이 줄어들게 되며 팽창장치 입구입구에서 가스가 발생되어 상기 팽창장치를 통과하는 냉매의 유량이 크게 줄어들면서 냉방효율이 저하되는 점 등의 문제점이 있었다.However, since the evaporator is installed far away from the condenser, the conventional method as described above increases the length of the refrigerant pipe connecting them, and the closed end of the refrigerant pressure drop due to the increased pipe length increases. As a result, the refrigerant pressure at the inlet of the evaporator unit is lowered and the difference between the refrigerant temperature and the condensation saturation temperature (supercooling) corresponding to the pressure of the refrigerant is reduced, thereby reducing the latent heat of evaporation. There was a problem in that the cooling efficiency is reduced while the gas is generated to significantly reduce the flow rate of the refrigerant passing through the expansion device.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 본 발명은 2개의 증발기를 구비한 차량용 에어컨 시스템에 있어서, 서로 직경이 다른 2개의 배관이 결합된 가스, 액체 열교환기 겸용 배관을 구비하고 상기 배관을 통하여 응축기에서 멀리 이격되어 배치되는 증발기 유닛의 팽창장치 입구에서 냉매의 과냉도를 증가시키도록 하므로서 증발기의 냉방능력을 향상시키며 액체배관과 가스배관을 일체형으로 형성하여 냉매배관의 설치를 용이하게 할 수 있도록 한 이중 증발기 구조를 가진 차량용 에어컨장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-described conventional problems, the present invention is a vehicle air conditioner system having two evaporators, provided with a gas, liquid heat exchanger combined pipe combined with two pipes of different diameters. And increase the supercooling of the refrigerant at the inlet of the expansion device of the evaporator unit spaced far from the condenser through the pipe, thereby improving the cooling capacity of the evaporator and forming the liquid pipe and the gas pipe as an integrated unit. It is to provide a vehicle air conditioner having a dual evaporator structure to facilitate the bar, which will be described in detail based on the accompanying drawings as follows.
