5. In a fifth step (S50) in which the refrigerant passing through the water-cooled condenser 20 or the air-cooled condenser 30 is changed to a low-temperature low-pressure refrigerant through the electronic expansion valve 40,

In the fifth step S50, the refrigerant passing through the water-cooled condenser 20 or the air-cooled condenser 30 passes through the electronic expansion valve 40 to lower the temperature and the pressure.

6. In a sixth step S60, the low-temperature low-pressure refrigerant passing through the electronic expansion valve 40 is circulated to the compressor 10 through the heat-exchanging function,

As a result of the refrigerant passing through the evaporator 50, the evaporator 50 exchanges the low-temperature low-pressure refrigerant through the electronic expansion valve 40 with the water supply.

Thus, the refrigerating function is enabled, and the refrigerant thus heat-exchanged continues to be repeatedly circulated to the compressor 10 described above.
