Abstract

본 발명은 공기조화기에 증발기로 이송되는 액체 및 기체냉매의 경로를 분지시키는 분지관의 위치를 어느정도만 대칭되게 설치하여도 냉매가 균일하게 분지되도록 하여 생산능률을 향상시키며, 또한 액체 및 기체 냉매를 균일하게 혼합시킨 상태에서 분무유동으로 분지되도록 하여 증발기의 열교환효율을 향상시키도록 한 공기조화기의 냉매분지장치에 관한 것으로, 액체와 기체냉매층을 없애고 내부의 2상(액체와 기체) 유동상태를 성류층이나 환상류에서 서리나 안개 등 분무유동으로바꾸어 팽창변에서 증발기로 이송되게 하는 혼합관(10)과, 혼합관(10)과 연결되어 설정된 압력으로 강하시켜 각 분지관(30a)(30b)에 걸리는 정압이 일정하게 유지되게 하여 분지관(30a)(30b)내로 들어가는 유량을 골고루 분배시켜 주는 서지탱크(20)와, 서지탱크(20)와 연결되어 증발기내로 냉매를 안내하는 분지관(30a)(30b)으로 구성한다.The present invention improves the production efficiency by uniformly branching the refrigerant even if the position of the branch pipe for branching the path of the liquid and gas refrigerant transferred to the evaporator to the air conditioner to some degree symmetrically, and also improves the liquid and gas refrigerant The present invention relates to a refrigerant branching device of an air conditioner that is branched into a spray flow in a uniformly mixed state to improve the heat exchange efficiency of an evaporator. The two-phase (liquid and gaseous) flow state is eliminated by removing a liquid and gas refrigerant layer. Is mixed with the mixing tube (10) and the mixing tube (10) to be transferred to the evaporator from the expansion valve by changing the spray flow, such as frost or mist in the current layer or annular flow, to each branch pipe (30a, 30b) Is connected to the surge tank 20 and the surge tank 20 to uniformly distribute the flow rate into the branch pipes 30a and 30b by maintaining a constant pressure applied to the branches. A branch pipe (30a, 30b) for guiding the refrigerant into the evaporator, for example.
