Patent number: 8775123Abstract: The present invention relates to a method for the determination of the coefficient of performance of a refrigeration machine, in particular of a heat pump, which includes a closed circuit which has a refrigerant and in which an evaporator, a compressor, a condenser and an expansion valve are arranged. In the method, at least three temperatures of the refrigerant are determined using temperature sensors arranged in the circuit. Alternatively, at least two temperatures and at least one pressure of the refrigerant is determined using sensors arranged in the circuit. Enthalpies of the circuit are calculated from the determined refrigerant temperatures and refrigerant pressures and the heat output and the taken up electrical power of the refrigeration machine are calculated therefrom to determine the coefficient of performance of the refrigeration machine from the quotient of the calculated heat output and the calculated taken up electrical power.Type: GrantFiled: December 10, 2009Date of Patent: July 8, 2014Assignee: Emerson Climate Technologies GmbHInventors: Hans-Jürgen Bersch, Raymond Steils

Publication number: 20110107775Abstract: A system comprises a condenser for a refrigeration system and a control module. The condenser has a plurality of variable speed condenser fans. The control module controls the plurality of variable speed condenser fans. The control module increases condenser fan operation by activating a deactivated variable speed condenser fan at a first fan speed when at least one variable speed condenser fan of the plurality is deactivated and by increasing a fan speed of an activated variable speed condenser fan to a second fan speed when each variable speed condenser fan of the plurality is activated and operating at the first fan speed. The second fan speed is faster than the first fan speed.Type: ApplicationFiled: January 18, 2011Publication date: May 12, 2011Applicant: EMERSON CLIMATE TECHNOLOGIES, INC.Inventors: Brian J. Akehurst, Hans-Juergen Bersch, Raymond Steils

Publication number: 20110107778Abstract: A method comprises monitoring an operating parameter of a refrigeration system that includes a first condensing unit having a first control module and a second condensing unit having a second control module, the first and second condensing units each having at least one compressor. The method also includes controlling, with the first control module, the at least one compressor of the first condensing unit based on the monitoring. The method also includes controlling, with the first control module, the at least one compressor of the second condensing unit based on the monitoring. The first control module controls the at least one compressor of the second condensing unit by communicating with the second control module via a communication link.Type: ApplicationFiled: January 18, 2011Publication date: May 12, 2011Applicant: EMERSON CLIMATE TECHNOLOGIES, INC.Inventors: Brian J. Akehurst, Hans-Juergen Bersch, Raymond Steils
