| description | A cold water supply system cools water flowing through a water pipe, and supplies the water cooled to a cooling load, the cold water supply system including: an independent refrigerant circuit unit including a first compressor and a first water heat exchanger configured to exchange heat between refrigerant and the water to cool the water; a composite unit configured to cool the water; and a controller configured to control operation of the independent refrigerant circuit unit and operation of the composite unit, wherein the composite unit includes a free cooling unit including a pump and a second water heat exchanger configured to exchange heat between a heat medium and the water to cool the water, and a coupled refrigerant circuit unit including a second compressor and a third water heat exchanger configured to exchange heat between refrigerant and the water to cool the water, and the controller controls an operating frequency of the first compressor, an operating frequency of the second compressor, and an operating frequency of the pump based on a temperature of the water flowing out from the water pipe. |
