The present invention relates to a heat pump apparatus for a refrigeration tower vehicle. More particularly, the present invention relates to a heat pump apparatus that configures an independent loop in which a refrigerant compressed by the compressor is branched and flows back into the compressor through an indoor heat exchange unit, in a refrigerant cycle comprising a compressor, an outdoor heat exchange unit, the indoor heat exchange unit, a freezer and a first expansion valve, and installs a control valve for controlling the amount of refrigerant flowing into the indoor heat exchange unit and an auxiliary heat exchange unit in the loop to adjust the amount of refrigerant flowing into the indoor heat exchange unit in the changing season when the heating demand is low.
본 발명은 냉동탑차의 히트펌프장치에 관한 것으로, 압축기; 실외열교환부; 실내열교환부; 냉동고; 제 1팽창밸브; 를 포함하는 공기조화기 냉매사이클에, 압축기에 의해 압축된 냉매가 분지되어 실내열교환부를 지나 다시 압축기로 유입되는 독립된 루프를 구성하고, 상기 루프에 실내열교환부로 유입되는 냉매량을 조절하는 조절밸브 및 냉매를 열교환시키는 보조열교환부를 설치하여 난방요구량이 적은 환절기에 실내열교환부로 유입되는 냉매량을 조절하고자 하는 히트펌프장치에 관한 것이다.
