Patent number: 9951975Abstract: A carbon dioxide refrigerant vapor compression system and method of operating that system are provided. The refrigerant vapor compression system includes a compression device, a flash tank receiver disposed in the refrigerant circuit intermediate a refrigerant heat rejection heat exchanger and a refrigerant heat absorption heat exchanger, and a compressor unload circuit including a refrigerant line establishing refrigerant flow communication between an intermediate pressure stage of the compression device and the refrigerant circuit at a location downstream of the refrigerant heat absorption heat exchanger and upstream of a suction inlet to the compression device, and a unload circuit flow control device disposed in said unload circuit refrigerant line. In response to at least one system operating parameter sensed by at least one sensor, the controller selectively positions the unload flow control device to maintain the refrigerant vapor compression system operating below a preselected high pressure limit.Type: GrantFiled: January 17, 2008Date of Patent: April 24, 2018Assignee: CARRIER CORPORATIONInventors: Yu H. Chen, Suresh Duraisamy, Lucy Yi Liu, Jason Scarcella, Zvonko Asprovski, Kursten Lamendola, Biswajit Mitra

Patent number: 8424337Abstract: A refrigerant vapor compression system is provided that includes a refrigerant circuit and a lubricant cooler circuit. The lubricant cooler circuit is operatively associated with the compression device for cooling a lubricant associated with the compression device and includes a heat exchanger coil disposed downstream of the refrigerant heat absorption heat exchanger with respect to the flow of heating medium. The lubricant cooler heat exchanger defines a flow path for passing the lubricant in heat exchange relationship with the cooled heating medium leaving the refrigerant heat absorption heat exchanger.Type: GrantFiled: January 17, 2008Date of Patent: April 23, 2013Assignee: Carrier CorporationInventors: Jason Scarcella, Kursten Lamendola

Publication number: 20100269523Abstract: A plurality of pressure relief devices are disposed within a refrigeration circuit, and each of the pressure relief devices is located within a compartment that fluidly communicates with the ambient air. Each of the pressure relief devices is oriented so that the release of high pressure vapor therefrom is directed to a rear wall of the compartment. Further, a four sided cover is disposed over each of the pressure relief devices so as to partially contain any released vapor and allow it to be discharged in one direction only.Type: ApplicationFiled: January 17, 2008Publication date: October 28, 2010Applicant: CARRIER CORPORATIONInventors: Zvonko Asprovski, Kursten Lamendola
