Abstract

본 발명의 목적은 실내열교환기와 실외 열교환기의 사이에 있는 액분리기와 압축기의 중간지점에 온도감지센서를 설치하며 또 상기 액분리기와 액분리기가 있는 반대쪽의 실외열교환기와 모세관 사이의 냉매관의 두곳에 이를 연결하는 전자밸브 및 바이패스용 모세관을 구비한 바이패스냉매관을 설치하되, 바이패스냉매관내 전자밸브를 상기 온도감지센서에 의해 동작하도록 한 것인데, 주위온도가 높은 상태에서 LOW 난방운전시에, 압축기 흡입부의 냉매온도를 감지하는 온도감지센서가 상기 바이패스냉매관내 전자밸브를 오픈시켜 실내열교환기와 모세관을 경유하여 1차 감압된 냉매를 바이패스냉매관으로 유입되게 하며 이 냉매를 다시 바이패스용모세관에서 2차감압시켜 액분리기로 유입시킴으로써 압축기로 유입되는 냉매의 온도를 낮게 하여 압축기의 계속 운전을 가능케 한다. 그결과 압축기의 연속동작으로 인한 연속적 난방운전으로 난방효율을 크게 증대시킬 수 있다.An object of the present invention is to provide a temperature sensor between a liquid separator and a compressor located between an indoor heat exchanger and an outdoor heat exchanger and to provide a temperature sensor between the liquid separator and the refrigerant tube between the outdoor heat exchanger and the capillary, A bypass refrigerant tube having a solenoid valve and a capillary tube for bypass is provided, and the solenoid valve in the bypass refrigerant tube is operated by the temperature sensor. In a state where the ambient temperature is high, A temperature sensing sensor for sensing the temperature of the refrigerant in the compressor suction unit opens the bypass valve in the refrigerant pipe so that the refrigerant having the first reduced pressure is introduced into the bypass refrigerant pipe via the indoor heat exchanger and the capillary tube, And the temperature of the refrigerant flowing into the compressor is lowered Enabling continuous operation of the compressor. As a result, the heating efficiency can be greatly increased by the continuous heating operation due to the continuous operation of the compressor.
