Provided in the present invention is a refrigerating cycle system for a refrigerator truck, which may reduce the temperature and pressure on the side of a receiver to facilitate the smooth introduction of a refrigerant circulating on the condenser side to reduce the load on the compressor and increase cooling performance, while efficiently removing a gaseous refrigerant contained in a liquefied coolant circulating towards the evaporator. To this end, the refrigerating cycle system for a refrigerator truck, in which a condenser, a blowing fan which radiates heat from the condenser to cool the same, and a receiver are disposed of in an outdoor unit case member which is fixedly installed at the upper portion of the front surface of the refrigerator truck, may comprise: a gaseous refrigerant transfer line which is installed to eject a refrigerant gas pooled at the upper portion of the receiver to the outside; a receiver heat exchanger which radiates heat to cool using air cooling in the process of circulating the refrigerant gas introduced through the gaseous refrigerant transfer line to be condensed in liquid; and a liquid refrigerant transfer line which sends the liquid refrigerant, condensed using the heat exchanger for the receiver, to the receiver. The heat exchanger for the receiver is installed at the upper side of the front surface in the outdoor unit case member to provide a higher potential energy than that of the receiver. Furthermore, the condenser is installed to be located at the lower side of the heat exchanger for the receiver.
본 발명은 수액기 측의 온도와 압력을 낮추어 응축기 측에서 순환하는 냉매의 원활한 유입을 촉진하여 압축기 부하를 줄이면서 냉각 성능을 향상하되 증발기 측으로 순환하는 액상냉매 속에 함유된 가스상 냉매를 효율성 좋게 제거할 수있는 구조의 냉동탑차용 냉동싸이클 시스템을 제공하는 데 있다. 이를 위해 응축기와 그 응축기를 방열 냉각하는 송풍팬 및 수액기를 냉동탑의 전면 상부에 고정설치되는 실외기 케이스부재 내에 마련하고 있는 냉동탑차용 냉동싸이클 시스템에 있어서, 상기 수액기 상부에 저류하는 냉매가스를 외부로 인출하도록 배설된 가스상냉매 이송라인과, 상기 가스상냉매 이송라인을 통해 유입된 냉매가스를 순환시키는 과정에 공랭에 의해 방열 냉각하여 액상으로 응축하는 수액기용 열교환기와, 상기 수액기용 열교환기를 통해 응축시킨 액상냉매를 수액기로 보내는 액상냉매 이송라인을 포함하고, 상기 수액기용 열교환기는 상기 수액기보다 높은 위치 에너지를 가지도록 상기 실외기 케이스부재 내의 전면 상측에 설치하고, 상기 응축기는 상기 수액기용 열교환기의 하측에 위치하도록 설치하고 있는 것을 특징으로 한다.
