Claims

[Scope of utility model registration request]

In a cooling system where a refrigeration cycle is mainly composed of a compressor, a condenser, an expansion valve, and an evaporator, a bypass pipe is provided parallel to the pipe in the middle of the pipe through which the refrigerant circulates in the refrigeration cycle, and the refrigerant flows through the bypass pipe. 1. A cooling device comprising a refrigerant tank for storing refrigerant and an on-off valve, and by opening and closing the on-off valve, the amount of refrigerant circulating within a refrigeration cycle can be made variable.
