Claims

[Scope of utility model registration request]

In the showcase in which the evaporator of the refrigeration circuit is provided in the case, the refrigerant from the compressor passes through the condenser, the main liquid line on-off valve, the expansion valve, and the cooling coil of the evaporator and is sucked into the compressor again. , a branch liquid line is provided which is branched from the primary side of the on-off valve in the main liquid line and connected to the middle of the flow path of the cooling coil in the evaporator, and in this branch line,
A multi-stage cooling showcase comprising an expansion valve and an opening/closing valve whose opening/closing operation is opposite to that of the main liquid reservoir/in opening/closing valve.
