Disclosed herein are compositions for cooling and heating comprising refrigerant consisting essentially of HFO-1225yeE, HFO-1234zeE, and optionally HFC-134. These compositions are useful in methods for cooling and heating, in systems for cooling and heating, and in methods for replacing HFO-1234zeE, R-515A or R-515B. The inventive compositions provide non-flammable, low GWP refrigerants that can match performance of HFO-1234zeE.

Compositions containing tetrafluoropropene, tetrafluoroethane and pentafluoropropene and uses thereof

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf, and CO. The compositions are useful in processes to produce cooling and heating, in methods for replacing refrigerant R-32, and in refrigeration, air conditioning or heat pump systems. These inventive compositions are match cooling performance for R-32 with GWP less than 400 or less than 300.

Compositions containing difluoromethane, tetrafluoropropene, and carbon dioxide and uses thereof

A method and apparatus for reclaiming refrigerant. The method includes transferring, an unreclaimed refrigerant composition, including one or more hydrofluoro olefins, from a source vessel to a receiving vessel and transporting the receiving vessel to a recycling center. The unreclaimed refrigerant composition is analyzed to determine the composition of the unreclaimed refrigerant composition sample. A target composition is determined, based on the analyzed unreclaimed refrigerant composition, and one or more treatments are determined, based on the target composition. The unreclaimed refrigerant composition is treated, with the one or more treatments, to form a reclaimed refrigerant composition having the composition of the reclaimed refrigerant composition is equal to the target composition.

Process and methods for reclaiming flammable and non-flammable hydrofluoro-olefin containing refrigerants

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf, and CO. The compositions are useful as refrigerants in processes to produce cooling and heating, in methods for replacing refrigerant R-410A, and in refrigeration, air conditioning or heat pump systems. These inventive compositions match cooling capacity for R-410A within 20% with GWP less than 250 or less than 200.

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise HFC-32, HFC-125, HFO-1234yf, HFC-134a, and CO. The refrigerant compositions are useful in processes to produce cooling and heating, in methods for replacing refrigerant R-410A or R-22, and in refrigeration, air conditioning or heat pump systems. These inventive compositions are non-flammable and match cooling performance for R-22 and R-410A within &#xb1;15%. Additionally, these compositions may serve as replacements for R-404A, R-507, R407A, R407C and/or R-407F in refrigeration, air conditioning or heat pump systems. The compositions as described herein have unexpected flammability properties.

Refrigerant mixtures comprising difluoromethane, pentafluoroethane, tetrafluoroethane, tetrafluoropropene, and carbon dioxide and uses thereof

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise a refrigerant mixture consisting essentially of HFC-32, HFO-1234yf, and CO. The compositions are useful as refrigerants in processes to produce cooling and heating, in methods for replacing refrigerant R-410A, and in refrigeration, air conditioning or heat pump systems. These inventive compositions match cooling capacity for R-410A within &#xb1;10% with GWP less than 400 or less than 300.

In accordance with the present invention refrigerant compositions are disclosed. The compositions comprise HFC-32, HFC-125, HFO-1234yf, HFC-134a, and CO. The refrigerant compositions are useful in processes to produce cooling and heating, in methods for replacing refrigerant R-R-22, and in refrigeration, air conditioning or heat pump systems. These inventive compositions are non-flammable and match cooling performance for R-22. The compositions as described herein have unexpected flammability properties.
