A cooling system for a hybrid vehicle that cools cooling medium for an air conditioner without reducing a driving performance, irrespective of a running condition. A detector detects data relating to operating conditions of a high-current device cooling circuit, a supercharger cooling circuit, a high-current device, an engine, a supercharger, and the hybrid vehicle. A controller selects one of a first water passage and a second water passage by manipulating a control valve based on the data collected by the detector, in such a manner as to maximize an amount of heat transferred from the cooling medium to high-current device cooling water or supercharger cooling water.
