Patent number: 9568206Abstract: Methods of controlling a cooling unit and embodiments of a cooling unit are disclosed. A method of improving efficiency of the cooling unit includes detecting a degree of opening of a hot gas bypass valve configured to divert a portion of coolant from a compressor to a heat exchanger of the cooling unit, and adjusting a condenser discharge pressure based on the detected degree of opening. Aspects may increase cooling efficiency at partial cooling requirements. Fluctuations in refrigerant pressure at low cooling capacities and condenser medium inlet temperature may be avoided. Minimum condenser water inlet temperature for a water-cooled cooling unit may also be reduced.Type: GrantFiled: August 21, 2009Date of Patent: February 14, 2017Assignee: SCHNEIDER ELECTRIC IT CORPORATIONInventor: Ozan Tutunoglu
