Claims (4)

압축기, 응축기, 감압기, 증발기, 액체저장탱크를 냉동관로로 순차로 연설한 냉동사이클에 있어서, 상기 증발기 또는 상기 액체저장탱크에 서리제거센서를 설치하고, 상기 증발기 근방에 히터를 설치하고, 서리제거 개시부터 상기 서리제거센서의 감지온도가 서리의 융점 이상으로 된때까지의 사이, 상기 히터를 구동하고, 상기 압축기를 소정 시간간격으로 단시간 운전하도록 한 것을 특징으로 하는 냉동사이클의 서리제거 제어방법.In a refrigeration cycle in which a compressor, a condenser, a pressure reducer, an evaporator, and a liquid storage tank are sequentially addressed to a freezing conduit, a defrost sensor is installed in the evaporator or the liquid storage tank, and a heater is installed near the evaporator. Defrost control method of a refrigeration cycle characterized in that the heater is driven and the compressor is operated for a short time at a predetermined time interval from the start of removal until the sensed temperature of the defrost sensor is above the melting point of frost. . 제1항에 있어서, 히터를 증발기의 냉매유입측 근방에 설치된 것을 특징으로 하는 냉동사이클의 서리제거 제어방법.The method of claim 1, wherein the heater is installed near the refrigerant inlet side of the evaporator. 압축기, 응축기, 감압기, 증발기, 액체저장탱크를 냉동관로로 순차로 연설한 냉동사이클에 있어서, 상기 증발기 또는 상기 액체저장탱크에 서리제거센서를 설치하고, 상기 증발기 근방에 히터를 설치하고, 상기응축기와 상기 감압기의 사이의 냉매관로에 냉매제어밸브를 설치하고, 상기 증발기와 상기 압축기의 사이의 냉매관로에 상기 압축기에서 상기 증발기에의 냉매의 흐름을 정지시키는 체크밸브를 설치하고 서리제거 개시부터 상기 서리제거센서의 감지온도가 서리의 융점 이상으로 될때까지의 사이, 상기 히터를 가열하고, 상기 압축기를 소정 시간간격으로 단시간 운전하며, 또한 이사이 압축기의 온·오프에 관계없이 항상 상기 냉매제어밸브를 개방한 채 고정한 것을 특징으로 하는 냉동사이클의 서리제거 제어방법.In a refrigeration cycle in which a compressor, a condenser, a pressure reducer, an evaporator, and a liquid storage tank are sequentially addressed to a freezing pipeline, a defrost sensor is installed in the evaporator or the liquid storage tank, and a heater is installed near the evaporator. A refrigerant control valve is installed in the refrigerant passage between the condenser and the pressure reducer, and a check valve for stopping the flow of refrigerant from the compressor to the evaporator is installed in the refrigerant passage between the evaporator and the compressor, and defrost is started. The heater is heated, the compressor is operated for a short time at a predetermined time interval and the refrigerant is always controlled regardless of the on / off of the moving compressor. Defrost control method of a refrigeration cycle characterized in that the valve is fixed while opening. 제3항에 있어서, 히터를 증발기의 냉매유입측 근방에 설치한 것을 특징으로 하는 냉동사이클의 서리제거 제어방법.4. The control method for defrosting a refrigeration cycle according to claim 3, wherein a heater is provided near a refrigerant inlet side of the evaporator. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
