れる。 As shown in FIG. 1, the refrigerant is pressurized by a compressor 21 to a saturated vapor pressure corresponding to the condensation temperature, and is sent to a condenser 22 where it is liquefied. The condensed liquid is stored in the refrigerant storage tank 32.
After passing through the expansion valve 23, the pressure is reduced to a saturated vapor pressure corresponding to a temperature 1 to 2 degrees Celsius lower than the freezing point of the brine, and then the brine is sprayed from the lower part of the heat storage can 25 into the heat storage can 25 from the nozzle 24. Further, a portion of the refrigerant liquid condensed in the condenser 22 is sent directly to the nozzle 24 .

The brine loses heat to the vapor of the refrigerant liquid, causing the temperature to drop and forming ice crystals in the brine. The ice crystals are stored in the heat storage tank 25 as a slurry with brine.

Then, heat exchange is performed with the brine in the heat storage tank 25, and the temperature of the cooling water is lowered. After the cooling water whose temperature has decreased is heat exchanged with the cooling air in the fan coil unit 35,
The cold water pump 34 sends the water to the heat exchanger 33 again.
