Abstract

본 발명은 1차팽창이후 어큐믈레이터에서 분리된 액냉매를 다시 2차팽창시켜 주므로서 팽창변입구의 과냉각도를 크게 한 것 같은 잠열의 효과를 도모하는 동시에 증발기 입구건도를 작게 하여 냉동효과를 상승시키도록한 에어컨의 어큐물레이터를 이용한 2단팽창냉동장치에 관한 것으로, 냉매가스를 고온, 고압으로 압축시키는 압축기(1)와, 압축기(1)에서 이송된 고온, 고압의 냉매가스를 방열시켜 점차적으로 액체상태로 상변화시키는 응축기(1)와, 응축기(2)에서 액체상태로 상변화되어 이송된 냉매를 저온의 액체 및 기체상태로 감압하는 1차팽창변(3)과, 1차팽창변(3)에서 이송된 저온의 액체와 기체상태의 냉매를 분리시켜 기체냉매만 압축기(1)로 바이패스시키도록 하는 어큐물레이터(4)와, 어규물레이터(4)에 저장된 액체냉매를 이송시키면서 다시 저온의 액체 및 기체상태로 감압팽창하는 2차팽창변(5)과, 2차팽창변(5)에서 이송된 저온의 액체 및 기체상태의 냉매를 통과시키면서 증발되어 주변열을 빼앗아 외부온도를 낮은 온도로 유지시키는 동시에 증발된 냉매가스를 바이패스된 냉매와 혼합하여 다시 압축기(1)로 이송시키도록 하는 증발기(6)로 에어컨의 어큐물레이터를 이용한 2단팽창냉동장치를 구성한다.Since the liquid refrigerant separated from the accumulator is re-inflated again after the first expansion, the effect of latent heat such as increasing the supercooling degree of the inlet of the expansion valve is improved, and the evaporator inlet quality is reduced, (1) for compressing a refrigerant gas to a high temperature and a high pressure, and a high-temperature and high-pressure refrigerant gas delivered from the compressor (1) to heat the refrigerant gas A first expansion valve (3) for reducing the pressure of the refrigerant transferred in the liquid state in the liquid state in the condenser (2) to a low temperature liquid and a gaseous state, and a second expansion valve An accumulator 4 for separating the low-temperature liquid transferred from the refrigerant separator 3 and the gaseous refrigerant so that only the gaseous refrigerant is bypassed to the compressor 1, and an accumulator 4 for transferring the liquid refrigerant stored in the accumulator 4 again A second expansion valve 5 for decompressing and expanding the liquid to a gaseous state and a second expansion valve 5 for vaporizing the ambient heat while passing the low temperature liquid and the gaseous refrigerant transferred from the second expansion valve 5, And the evaporator 6 mixes the evaporated refrigerant gas with the bypassed refrigerant and transfers it to the compressor 1. The evaporator 6 constitutes a two stage expansion refrigerating apparatus using an air conditioner accumulator.
