Abstract

1. 청구범위의 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

본 발명은 슈퍼마켓등 점포에 설치되어 냉기를 저장실로 순환시켜 저장실 내부를 냉각하는 저온 쇼케이스에 관한 것이다.The present invention relates to a low temperature showcase installed in a store such as a supermarket and circulating cold air to a storage room to cool the storage compartment.

2. 발명이 해결하려고 하는 기술적과제2. Technical Challenges to be Solved by the Invention

종래의 저온 쇼케이스는 그 용도에 따른 각각의 온도대에 대응하여 냉매회로를 형성하므로서 냉동실용 쇼케이스에도 응축유니트를 별도설치하고 있는바 이로 인한 코스트의 증가, 배관접속의 다수화로 인한 가스누출위험성등 문제를 해결하고 점포내의 배관의 간소화와 환경악화의 억제를 실현할 수 있는 저온 쇼케이스를 제공한다.Conventional low-temperature showcase forms a refrigerant circuit corresponding to each temperature range according to its use, and a condensation unit is additionally installed in a refrigerator-use showcase. This increases the cost and the risk of gas leakage due to a large number of piping connections Temperature showcase capable of realizing simplification of piping in a store and suppression of environment deterioration.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

냉동케이스(3)은 냉기를 저장실(39)내에 순환시켜 냉각하는 것으로서 기계실등에 설치된 별도설치형 응축유니트로부터 냉매가 공급되는 주증발기(46)과 상기 냉동케이스(3)에 설치된 내장형 응축유니트(57)로부터 냉매가 공급되는 보조증발기(47)을 구비하여 구성되어 있다.The freezing case 3 is a device for cooling the cold air by circulating the cold air in the storage chamber 39 and is equipped with a main evaporator 46 for supplying the refrigerant from a separate installation type condensing unit installed in the machine room and an internal condensing unit 57 installed in the refrigeration case 3, And an auxiliary evaporator 47 to which the refrigerant is supplied.

4. 발명의 중요한 용도4. Important Uses of the Invention

보조증발기(47)에 의해서 저온 쇼케이스의 저장실내부를 별도 설치된 응축유니트에 접속된 다른 저온 쇼케이스보다 낮은 온도대로 냉각할 수 있고 내장형 응축유니트의 소형화와 폐열, 소음을 저감하고 에너지손실을 경감할 수 있다.The inside of the storage room of the low temperature showcase can be cooled to a temperature lower than that of other low temperature showcase connected to the separate condenser unit by the auxiliary evaporator 47 and the miniaturization of the built-in condenser unit, the waste heat and noise can be reduced and the energy loss can be reduced .
