Claims

[Scope of claim for utility model registration] (1) A compressor, condenser,
In the apparatus in which an evaporator of a refrigeration cycle is cyclically connected to an accumulator, an expansion valve, an evaporator, and an evaporation pressure regulating valve, and a blower for circulating air cooled by the evaporator into the refrigerator. The refrigerant outlet of the refrigerant gas section of the accumulator and the refrigerant outlet or refrigerant inlet of the evaporator are connected by a bypass pipe via a solenoid valve and a throttle valve, and the solenoid valve is installed outside the device, and a signal is received from a temperature sensor. A heat-retaining cabinet configured to open and close based on the following. (2) Utility model registration claim No. 1 characterized in that the accumulator side of the bypass pipe and the refrigerant outlet of the evaporation pressure regulating valve are communicated via a constant pressure expansion valve.
Thermal storage described in (1).
