20090127497 | HYDROFLUOROCARBON/TRIFLUOROIODOMETHANE/ HYDROCARBONS REFRIGERANT COMPOSITIONS - A composition comprising from about 40 weight percent to about 99.9 weight percent of at least one C | 05-21-2009 |
20110219815 | HEAT TRANSFER COMPOSITIONS AND METHODS - 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 | 09-15-2011 |
20130145778 | HEAT TRANSFER COMPOSITIONS AND METHODS - 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. | 06-13-2013 |
20130186115 | LOW GWP HEAT TRANSFER COMPOSITIONS - Heat transfer compositions and methods including (a) HFC-32; (b) HFO-1234ze; and (c) either or both of HFC-152a and/or HFC-134a. | 07-25-2013 |
20140047860 | LOW GWP HEAT TRANSFER COMPOSITIONS - 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 —CF3 terminated propenes, unsaturated —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. | 02-20-2014 |
20140137578 | LOW GWP HEAT TRANSFER COMPOSITIONS - The present invention relates, in part, to heat transfer and refrigerant compositions and methods that include HFC-32; HFO-1234ze and HFC-125. | 05-22-2014 |
20150089965 | HEAT TRANSFER COMPOSITIONS AND METHODS - 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 | 04-02-2015 |
