US Patent:

20100269523, Oct 28, 2010
Filed:

Jan 17, 2008
Appl. No.:

12/745763
Inventors:

Zvonko Asprovski - Liverpool NY, US
Kursten Lamendola - Chittenango NY, US
Assignee:

CARRIER CORPORATION - Farmington CT
International Classification:

F25B 41/04
F25B 1/00
US Classification:

62174, 62498
Abstract:

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.

20100271221, Oct 28, 2010
Filed:

Jan 17, 2008
Appl. No.:

12/745757
Inventors:

Zvonko Asprovski - Liverpool NY, US
Suresh Duraisamy - liverpool NY, US
Assignee:

CARRIER CORPORATION - Farmington CT
International Classification:

G08B 17/10
F25B 49/00
US Classification:

340632, 62129
Abstract:

A refrigerated container having a refrigeration system using COas the refrigerant, includes a sensing and warning system for sensing the COconcentration in the container and responsively displaying the sensed condition in a display module so that an operator will be aware of excess levels of concentration which might present a hazardous condition and therefore should not enter the container until the condition is alleviated.

International Classification:

F25B 1/00
F25B 41/04
US Classification:

62115, 62222
Abstract:

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.

US Patent:

20120145248, Jun 14, 2012
Filed:

Aug 24, 2010
Appl. No.:

13/390377
Inventors:

Hans-Joachim Huff - Mainz, DE
Jason Scarcella - Cicero NY, US
Lucy Yi Liu - Fayetteville NY, US
Suresh Duraisamy - Liverpool NY, US
Zvonko Asprovski - Liverpool NY, US

Gilbert B. Hofsdal - Chittenango NY, US
Assignee:

CARRIER CORPORATION - Farmington CT
International Classification:

F16K 37/00
US Classification:

137 1, 137557
Abstract:

An activation indicator for a refrigeration system pressure relief valve is presented. In one embodiment, the indicator comprises a covering that covers an outlet passage of the pressure relief valve. The covering is at least partially displaceable by refrigerant as it exits the refrigeration system through the pressure relief valve. In another embodiment, sensors outputting a signal transmit an altered signal when the relief device releases refrigerant. A notification device is activated to indicate that the pressure relief device has activated.
