PROBLEM TO BE SOLVED: To stabilize temperature of cold water to be supplied to an air conditioner, maintaining a constant room temperature. SOLUTION: A temperature detector 52 monitors the temperature of water circulating among a cold water bath 18, and refrigerators 36, 38, 40. A flow meter 48 monitors the flow of the cold water heat-exchanged by the air conditioner 12. A controller 46 controls the refrigerator 36 to stop/start according to the temperature monitored by the temperature detector 52 and controls the refrigerators 38, 40 to stop/start according to the flow monitored by the flow meter 48. Not only the temperature of the cold water, but also the flow rate of the cold water heat-exchanged by the air conditioner 12 are employed as a condition for the refrigerators to stop/start, allowing minimized temperature variation of the cold water to be supplied to the air conditioner 12 with respect to a predetermined temperature, thus stabilizing conditions for air conditioning.
