である。In general, in refrigerators that cool the fluid or air outside the evaporator by circulating a refrigerant such as ammonia or chlorofluorocarbon in the evaporator, such as ice makers, refrigerators, or coolers, in order to increase the refrigeration capacity of the evaporator, An important issue is how to defrost the heavy ice or frost on the surface of the evaporator in a short time.

場合保管物を傷める等の不都合が存した。However, conventional defrosting equipment takes a long time to defrost because it involves pressurizing high-temperature gas into the evaporator from the compressor discharge side, spraying water on the evaporator, or heating the evaporator with an electric heater. However, there were disadvantages such as overheating of the evaporator and damage to stored items in the case of refrigerators.

いる。図中（１１）は膨張弁を示す。The present invention has been made to improve such inconveniences, and when the necessity of defrosting the refrigerating machine is detected by a detection means such as a timer or a pressure switch, the compressor An object of the present invention is to provide a device in which a liquid at normal temperature in a condenser or liquid receiver on a discharge side is rapidly circulated between an evaporator and a condenser using a pump to defrost the liquid in a short time. To explain an example, (1) is a compressor, (2) is a condenser, and (3) is an evaporator. A refrigerant circulation path (4) consisting of #1) is formed, and #condensed N (2) and evaporation! (3) and between the evaporator (3) and the compressor (1), normally open electromagnetic switching valves (5) and (6) are provided, respectively. (7) indicates a defrosting circulation path, which consists of a 71+j condenser (21, a pump (81), an evaporation lid (3), and a condenser (2),
Furthermore, the circulation path (7) includes a pump (8) and an evaporator #(3).
Normally open electromagnetic switching valves (9) and (10) are provided between the evaporator (3) and the condenser (2), respectively. In the figure, (11) indicates an expansion valve.
