Refrigerant Vapor Compression System And Method Of Transcritical Operation

View page
US Patent:
8424326, Apr 23, 2013
Filed:
Apr 24, 2007
Appl. No.:
12/596883
Inventors:
Biswajit Mitra - Charlotte NC, US
Yu H. Chen - Manlius NY, US
Jason Scarcella - Cicero NY, US
Suresh Duraisamy - Liverpool NY, US
Lucy Yi Liu - Fayetteville NY, US
Assignee:
Carrier Corporation - Farmington CT
International Classification:
F25B 41/00
F25B 39/04
F25B 1/10
US Classification:
621961, 62509, 62510
Abstract:
A refrigerant vapor compression system includes a flash tank economizer defining a separation chamber is disposed in the refrigerant circuit intermediate a refrigerant heat rejection heat exchanger and a refrigerant heat absorption heat exchanger. A primary expansion valve is interdisposed in the refrigerant circuit in operative association with and upstream of the refrigerant heat absorption heat exchanger and a secondary expansion valve is interdisposed in the refrigerant circuit in operative association and upstream of the flash tank economizer. A refrigerant vapor injection line establishes refrigerant flow communication between an upper portion of the separation chamber and an intermediate pressure stage of the system's compression device and a suction pressure portion of the refrigerant circuit. A refrigerant liquid injection line establishes refrigerant flow communication between a lower portion of said separation chamber and an intermediate pressure stage of the compression device and a suction pressure portion of the refrigerant circuit.

Refrigerant Vapor Compression System With Flash Tank Receiver

View page
US Patent:
8459052, Jun 11, 2013
Filed:
Jan 12, 2011
Appl. No.:
13/005228
Inventors:
James W. Bush - Skaneateles NY, US
Wayne P. Beagle - Chittenango NY, US
Biswajit Mitra - Charlotte NC, US
Assignee:
Carrier Corporation - Farmington CT
International Classification:
F25B 41/04
US Classification:
62222, 62430
Abstract:
A refrigerant vapor compression system includes a flash tank receiver disposed in the refrigerant circuit intermediate the refrigerant cooling heat exchanger and the refrigerant heating heat exchanger. The flash tank receiver, which receives a liquid/vapor refrigerant mix, also functions as a receiver. A refrigerant charge control apparatus includes at least one sensor for sensing an operating characteristic of the refrigerant circulating through the refrigerant compression device, and a controller operative to selectively adjust a secondary expansion device to increase or decrease the flow of refrigerant passing into the flash tank receiver to provide a circulating refrigerant charge consistent with maintaining a desired system operating characteristic. The sensed operating characteristic is at least one of (a) the vapor refrigerant passing through a refrigerant line from the flash tank receiver to an intermediate pressure stage of the compression device, and (b) the refrigerant discharged from the compression device.
