Claims

[Scope of claim for utility model registration] (1) A storage room covered with a casing made of a heat insulating material and a door body made of a heat insulating material, and a compressor, a condenser, an expansion valve, and an evaporator arranged inside the storage room. and a device comprising an evaporator of a refrigeration cycle connected in circulation to an evaporation pressure adjustment valve, and a blowing fan that circulates air cooled by the evaporator into a storage chamber, wherein the evaporation pressure adjustment valve controls the evaporation of the evaporator. A solenoid valve and a capillary reach tube are connected in parallel with the expansion valve, and the solenoid valve is opened and closed by a low pressure switch connected to the refrigerant outlet side of the evaporation pressure regulating valve. A refrigeration device comprising: (2) A cylindrical container having a refrigerant outlet and a refrigerant inlet at different positions of the evaporation pressure regulating valve, a partition plate installed in the container and partitioning the inside of the container into a refrigerant outlet side and a refrigerant inlet side, and the partition A valve seat is biased by a biasing means such as a spring by opening and closing an orifice provided on a plate from the refrigerant inlet side, and a screw threaded into the inner wall of the container that moves the biasing means back and forth relative to the orifice. A refrigeration device according to claim 1, characterized in that the refrigeration device is comprised of a body and a body. (3) A request for utility model registration characterized in that the refrigeration cycle is constructed such that the temperature difference between the refrigerant temperature at the evaporator outlet and the air temperature near the evaporator outlet is 2.5°C or less.
