The expansion valve connected to the downstream side of the liquid tank adiabatically expands the liquid refrigerant to make a gas-liquid mixed refrigerant, and the evaporator inserts a titanium pipe inside the rubber hose and inserts it into the titanium pipe. Can be configured so that a refrigerant flows, and water in the water tank 1 flows between the titanium pipe and the rubber hose. The state change of the refrigerant and the cooling operation of the water in the water tank 1 in the cooling device of the cooling / sterilizing device 12 configured as described above are performed as follows. That is, first, the refrigerant sucked into the compressor in the state of superheated steam is adiabatically compressed by the compressor, becomes a high-temperature and high-pressure gaseous refrigerant, and is guided to the condenser.
At this point, heat is released to form a medium-temperature, high-pressure liquid refrigerant. Next, this liquid refrigerant is adiabatically expanded by passing through the expansion valve to become a gas-liquid mixed refrigerant, and then guided to an evaporator to perform heat exchange with water in the water tank 1 and to perform equal pressure expansion while evaporating. Then, it becomes superheated steam and is sucked into the compressor again. Note that a sterilizing device of the cooling / sterilizing device 12 uses a general sterilizing lamp.
