Provided are azeotrope-like compositions consisting essentially of 1,1,1,2-tetrafluoropropene and 1,1,1,2-tetrafluoroethane and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agent compositions, and aerosol propellants.

Azeotrope-like compositions of 1,1,1,2-tetrafluoropropene and 1,1,1,2-tetrafluoroethane

The present invention relates, in part, to heat transfer compositions, methods, and uses thereof that include (a) from about 17% to about 40% by weight of HFC-32; (b) from about 51% to about 83% by weight of a tetrafluoropropene; and (c) from greater than about 0% to less than about 9% by weight of CO2. The amount of component (c) improves one or more of a capacity, efficiency, discharge temperature, discharge pressure, and/or energy consumption of the composition, particularly in a low or medium temperature refrigeration system and as compared to composition lacking component (c) and/or the refrigerant R-404A.

Low GWP heat transfer compositions

Heat transfer systems, methods and compositions which utilize a heat transfer fluid comprising: (a) from about 30% to about 65% by weight of HFC-134a; (b) from about 0% to about 70% by weight of HFO1234ze; and (c) from about 0% to about 70% by weight of HFO-1234yf, provided that the amount of HFO-1234ze and HFO-1234yf in the composition together is at least about 35% by weight, with the weight percent being based on the total of the components (a)-(c) in the composition.

Compositions and methods for refrigeration

Compositions, methods and systems which comprise or utilize a multi-component mixture comprising: (a) HFC-32; (b) HFC-125; (c) HFO-1234ze, HFO-1234yf and combinations of these; and (d) optionally HFC-134a.

Heat transfer compositions and methods

A composition comprising from about 40 weight percent to about 99.9 weight percent of at least one C-Chydrofluorocarbon, from about 0.1 weight percent to about 50 weight percent of CF3I, and from about 0.1 weight percent to about 10 weight percent of at least one C-Chydrocarbon and the use of these composition for in methods of the recharging of refrigeration systems.

Hydrofluorocarbon/trifluoroiodomethane/ hydrocarbons refrigerant compositions

The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms.

The present invention relates, in part, to heat transfer compositions, and associated systems and methods, which include a first composition selected from the group consisting of HFO-1233zd, HFC-245fa, and combinations of these; and, optionally, a second composition selected from the group consisting of HFO-1234ze, HFC-134a, and combinations of these.

Low GWP fluids for high temperature heat pump applications

Heat transfer compositions, methods and use wherein the composition comprising: (a) from about 5 to about 20% by weight of HFC-32 and (b) from about 80% to about 95% by weight of HFO-1234ze.

Low GWP heat transfer compositions containing difluoromethane and 1,3,3,3-tetrafluoropropene

Compositions, methods and systems which comprise or utilize a multi-component mixture comprising: (a) HFC-32; (b) HFC-125; (c) HFO-1234yf and/or HFO-1234ze; (d) HFC-134a. In certain non-limiting aspects, such refrigerants may be used as a replacement for R-404A.

The present invention relates, in part, to heat transfer compositions and methods that include (a) from about 65% to about 75% by weight of HFC-32; (b) from about 15% to about 35% by weight of a compound selected from unsaturated &#x2014;CF3 terminated propenes, unsaturated &#x2014;CF3 terminated butenes, and combinations of these; and (c) from greater than about 0% to less than about 10% by weight of CO2, provided that the amount of component (c) is effective to improve heating capacity of the composition and reduce the defrost cycle in refrigerant applications, as compared to compositions lacking this component.

Compositions, methods and systems which comprise or utilize a multi-component mixture comprising: (a) from about 10% to about 35% by weight of HFC-32; (b) from about 10% to about 35% by weight of HFC-125; (c) from about 20% to about 50% by weight of HFO-1234ze, HFO-1234yf and combinations of these; (d) from about 15% to about 35% by weight of HFC-134a; and optionally (e) up to about 10% by weight of CF3I and up to about 5% by weight of HFCO-1233ze, with the weight percent being based on the total of the components (a)-(e) in the composition.
