The present invention relates to a freezing system for a freezer truck for low-temperature transportation. The freezing system includes: a compressor (100) compressing a refrigerant with high pressure and high temperature to discharge the refrigerant; a condenser (200) converting the refrigerant compressed by the compressor (100) into vapor-phase refrigerant liquid by exchanging heat between the refrigerant and outdoor air; an expansion valve (300) converting the refrigerant liquid condensed by the condenser (200) into a low temperature and low pressure refrigerant while making the refrigerant liquid go through itself; an evaporator (400) converting the low temperature and low pressure refrigerant having gone through the expansion valve (300) into vapor while keeping its temperature low by exchanging heat between indoor air and the refrigerant, thereby circulating the refrigerant to the compressor (100); and a thermo bank (500) installed to be penetrated by a refrigerant pipe, which connects a refrigerant outlet of the compressor (100) to a refrigerant inlet of the condenser (200), to store heat from the high temperature refrigerant discharged from the compressor (100). An ejector (600) is installed in the refrigerant pipe near the downstream of the condenser. The ejector (600) enables the refrigerant liquid having gone through the condenser (200) to flow in through a primary inlet (601) and enables the refrigerant vapor evaporated by the evaporator (400) to flow in through a secondary inlet (610), and then, mixes the liquid and the vapor internally to transfer the mixture.

    본 발명은 저온 수송 냉동차량용 냉동시스템에 관한 것으로, 특히 냉매를 고온,고압으로 압축하여 토출하는 압축기(100), 압축기(100)에서 압축된 고온,고압의 냉매를 외부의 공기와 열교환시켜 증기상의 냉매를 액상의 냉매액으로 변화시키는 응축기(200)와, 응축기(200)에서 응축된 액상의 냉매를 통과시키면서 저온,저압의 냉매로 변환시키는 팽창밸브(300)와, 팽창밸브(300)를 거친 저온,저압의 냉매를 고내의 내부공기와 열교환하여 고내의 내부온도를 저온으로 유지시키고 증기로 변환시켜 압축기(100)로 순환시키는 증발기(400)와, 상기 압축기(100)의 냉매 토출구와 응축기(200)의 냉매 유입구를 연결하는 냉매배관이 통과하도록 설치되어, 압축기(100)에서 토출되는 고온의 냉매로부터 축열하는 써모 뱅크(500)를 포함하고, 상기 응축기(200)의 하류측 냉매배관에 이젝터(600)가 설치되고, 상기 이젝터(600)는 응축기(200)를 통과한 냉매액을 1차 유입구(601)을 통하여 유입시키고 증발기(400)에서 증발되는 냉매증기를 2차 유입구(610)를 통하여 유입시켜, 내부에서 혼입한 후 이송한다.
