Abstract

A water cooling apparatus (A1 ,A2, A3) comprises a compressed air cooler (12) for cooling compressed air, a wet-type water cooler (13) into which condensed water generated by the compressed air cooler (12) is introduced as makeup water, a cooling water pump (14) which sends the cooling water discharged from the wet-type water cooler to a cold end of the compressed air cooler to cool the compressed air by the cooling water, a dry-type water cooler (15) for cooling warm water discharged from a warm end of the compressed air cooler and a first flow rate regulating valve (121) for regulating the flow rate of the condensed water.
