Patent number: 8261561Abstract: An air conditioning system having a free-cooling mode. The system includes a refrigeration circuit have a compressor, a pump, an expansion device having a variable opening, and a controller. The controller selectively operates the system in the free-cooling mode by circulating the refrigerant through the refrigeration circuit via the pump. The system includes a free-cooling capacity control sequence resident on the controller. The free-cooling capacity control sequence adjusts the cooling capacity of the system at least by adjusting the variable opening based on the temperature difference between a working fluid temperature and a set point temperature.Type: GrantFiled: December 28, 2006Date of Patent: September 11, 2012Assignee: Carrier CorporationInventors: Philippe Rigal, Pierre Delpech, Batung Pham

Publication number: 20100036530Abstract: An air conditioning system having a cooling mode and a free-cooling mode is provided. The system includes a refrigeration circuit, two pressure sensors, a controller, and a pump starting sequence resident on the controller. The refrigeration circuit includes a compressor and a pump. The first pressure sensor is at an inlet of the pump, while the second pressure sensor is at an outlet of the pump. The controller selectively operates in the cooling mode by circulating and compressing a refrigerant through the refrigeration circuit via the compressor or operates in the free-cooling mode by circulating the refrigerant through the refrigeration circuit via the pump. The pump starting sequence cycles the pump between an on state and an off state based at least upon a differential pressure determined by the controller from pressures detected by the pressure sensors.Type: ApplicationFiled: December 22, 2006Publication date: February 11, 2010Applicant: CARRIER CORPORATIONInventors: Julien Chessel, Pierre Delpech, Jean-Philippe Goux
