Abstract

본 발명은 냉동 장치의 냉동싸이클에 관한 것으로, 이는 주냉각기 이외에 별도의 보조냉각기를 구비함과 아울러 냉동싸이클을 따라서 순환하는 냉매의 흐름을 제어할 수 있는 다수개의 전자변을 구비하여 냉동장치 내에 수납된 저장물의 급속냉각이 가능해지고 주냉각기와 보조냉각기의 제상작업이 제상히터와 같은 별도의 발열체에 의하지 않고 고온의 냉매에 의하여 이루어짐으로써 냉동장치 내에 수납된 저장물의 신선도가 가일층 향상되며 냉동장치의 소비전력이 절감되는 냉동장치의 냉동싸이클을 제공함을 목적으로 하며, 그 기술적인 수단으로써 본 발명은 냉매를 압축하는 압축기(10)와, 냉매를 팽창시키는 캐필러리 튜브(40)와, 냉매가 관류하며 외부 공기를 냉각시키는 주냉각기(50)등을 포함하는 구성으로 이루어진 냉동장치의 냉동싸이클에 있어서; 상기 캐필러리튜브(40)를 통과한 냉매가 유입되어 외부공기를 냉각시키는 보조냉각기(60)와, 상기 캐필러리튜브(40)을 통과한 냉매의 흐름을 제어하는 제1전자변(80)과, 상기 제1전자변(80)을 통과한 냉매가 상기 보조냉각기(60)로 유입되는 것을 제어하는 제2전자변(82)과, 상기 주냉각기(50)에서 배출된 냉매의 흐름을 제어하는 제3전자변(84)과, 상기 압축기(10)에서 토출된 냉매가 상기 주냉각기(50)로 곧장 유입되는 것을 제어하는 제4전자변(86)을 포함하는 구성으로 이루어진 것을 특징으로 한다.The present invention relates to a refrigeration cycle of a refrigerating device, which includes a separate subcooler in addition to the main cooler and is provided in a refrigerating device having a plurality of electronic valves capable of controlling the flow of refrigerant circulating along the freezing cycle. The rapid cooling of the storage is possible, and the defrosting operation of the main cooler and the subcooler is performed by a high temperature refrigerant instead of a separate heating element such as a defrost heater, which further improves the freshness of the storage stored in the freezing device. It is an object of the present invention to provide a refrigeration cycle of the refrigerating device, and the technical means of the present invention provides a compressor 10 for compressing a refrigerant, a capillary tube 40 for expanding the refrigerant, and a refrigerant flowing through In the refrigeration cycle of the refrigerating device consisting of a main cooler (50) for cooling the outside air In; The refrigerant passing through the capillary tube 40 flows in the subcooler 60 to cool external air, and the first electronic valve 80 controlling the flow of the refrigerant passing through the capillary tube 40. And a second electron valve 82 which controls the introduction of the refrigerant passing through the first electron valve 80 into the subcooler 60, and a control of the flow of the refrigerant discharged from the main cooler 50. It is characterized in that it comprises a configuration comprising a three electron valve 84, and a fourth electron valve 86 for controlling the refrigerant discharged from the compressor 10 to flow directly into the main cooler (50).
