Abstract

본 발명은 냉장고의 냉각장치에 관한 것으로서, 응축기와 증발기 사이에 형성된 전자팽창밸브의 개폐를 통해 냉매의 유량을 조절하여 증발기의 압력을 원하는 수준으로 조절함으로서 냉장고의 효율을 향상시키도록 한 것이다.The present invention relates to a refrigerator of a refrigerator, and to improve the efficiency of the refrigerator by controlling the flow rate of the refrigerant to a desired level by controlling the flow rate of the refrigerant by opening and closing the electronic expansion valve formed between the condenser and the evaporator.

이와같은 본 발명의 목적은 증발기 입출구의 온도를 감지하도록 증발기 입출구에 온도감지수단을 형성하고, 상기 온도감지수단에 의하여 감지된 증발기 입출구의 온도는 증발기 출구온도가 입구온도보다 높게 되도록 개폐되는 시간의 비율에 의해서 냉매의 유량을 조절하는 유량조절수단을 형성함으로서 상기의 목적을 이룰 수 있도록 하였다.The object of the present invention is to form a temperature sensing means at the evaporator inlet and outlet to detect the temperature of the evaporator inlet and outlet, the temperature of the evaporator inlet and outlet detected by the temperature sensing means of the time to be opened and closed so that the evaporator outlet temperature is higher than the inlet temperature. It was possible to achieve the above object by forming a flow rate adjusting means for adjusting the flow rate of the refrigerant by the ratio.
