Abstract
A cooling system includes; an evaporator evaporating a refrigerant by heat exchange with room air; a water-cooled condenser being arranged above the evaporator and condensing the refrigerant by heat exchange with cold water; a cold-water flow control valve controlling the flow rate of the cold water supplied to the water-cooled condenser; a refrigerant cooling tower being arranged above the evaporator and condensing the refrigerant by heat exchange with outside air; a blower being arranged at the refrigerant cooling tower and blowing the outside air; a refrigerant-temperature detector detecting the temperature of the refrigerant condensed by the water-cooled condenser and/or the refrigerant cooling tower; and a controller changing at least one of the opening in the cold-water flow control valve and the rotational speed of a motor in the blower according to the temperature.
