Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A cooling system comprising: an evaporator which evaporates a refrigerant by heat exchange with room air subject to air conditioning; a water-cooled condenser which is arranged at an elevation higher than an elevation at which the evaporator is arranged, and condenses the refrigerant by heat exchange with cold water when the refrigerant flows into the water-cooled condenser from the evaporator through a portion of a piping arrangement; a cold-water flow…
