In the step (S10), the ice storage water, which is the secondary refrigerant at room temperature, is stored in the water tank 10.

In the step (S20), the cooling unit 30 is driven, and the primary refrigerant is forcibly circulated therein to exchange heat with ice water to cool the ice water.

For example, the temperature of the ice water is cooled to 5°C or less. The ice water temperature may be set to 0°C to 5°C or less, preferably 5°C or less, which may be variously changed according to the installation location and design conditions.

In the step S30, raw water cooled to 5° C. or less while passing through the cold water coil 21 of the direct water line 20 is supplied to a supply destination through, for example, a cold water maker.
