Abstract

본 발명은 슈퍼 및 백화점등에 설치되는 제품으로서 제품의 전면에 도어가 없이 층류의 공기를 송풍시켜 내부의 냉기를 보관하는 오픈 쇼케이스의 온도 제어에 관한 것으로, 외부의 온도가 오픈 쇼케이스 내부의 온도보다 낮을 경우 외기 온도센서를 이용하여 종래와 같이 냉각운전이 진행되게 하고, 외부의 온도가 더 낮을 경우, 외기를 자연 유입시키는 상태에서 외부로 부터 유입되는 외기의 온도가 일정온도 이하로 하강되는 경우, 히터를 이용하여 과냉이 방지되게 한 것이다.The present invention relates to the temperature control of the open showcase to store the cool air inside by blowing the laminar flow air without a door on the front of the product as a product installed in the supermarket and department stores, the outside temperature is lower than the temperature inside the open showcase In the case of using the external air temperature sensor to allow the cooling operation to proceed as in the prior art, and when the external temperature is lower, when the temperature of the external air introduced from the outside falls below a certain temperature in a state of naturally introducing the external air, the heater Using to prevent overcooling.
