Compositions comprising multi-fluorinated olefins and HFC-32 are disclosed. Such compositions are useful particularly for in stationary refrigeration and air conditioning equipment.

Compositions containing difluoromethane and fluorine substituted olefins

Disclosed are fire extinguishants comprising from about 20% to about 80% by weight of 1-chloro-3,3,3-trifluoropropene (HFO-1233zd) and from about 20% to about 80% by weight of 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone (FK5-1-12), and to methods, systems and containers which use the fire extinguishants.

Fire extinguishing compositions, systems and methods

The present invention relates to a refrigerant composition, including difluoromethane (HFC-32), pentafluoroethane (HFC-125), and trifluoroiodomethane (CFI) for use in a heat exchange system, including air conditioning and refrigeration applications and in particular aspects to the use of such compositions as a replacement of the refrigerant R-410A for heating and cooling applications and to retrofitting heat exchange systems, including systems designed for use with R-410A.

Heat transfer compositions, methods and systems

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

Provided are azeotrope-like compositions comprising heptafluoropropane and trifluoroiodomethane and uses thereof, including use in refrigerant compositions, refrigeration systems, blowing agents, fire suppressant compositions, and aerosol propellants.

Azeotrope-like compositions of pentafluoroethane and trifluoroiodomethane

A dielectric gaseous compound which exhibits the following properties: a boiling point in the range between about &#x2212;20&#xb0; C. to about &#x2212;273&#xb0; C.; non-ozone depleting; a GWP less than about 22,200; chemical stability, as measured by a negative standard enthalpy of formation (dHf&#x3c;0); a toxicity level such that when the dielectric gas leaks, the effective diluted concentration does not exceed its PEL; and a dielectric strength greater than air.

Gaseous dielectrics with low global warming potentials

Azeotrope-like compositions of heptafluoropropane and trifluoroiodomethane

A method for suppressing an electric arc or corona discharge includes providing a device capable of storing, transmitting, or generating an electrical current or field; and enveloping at least a portion of said device with a dielectric gas consisting essentially of: sulfur hexafluoride; a second component selected from the group consisting of nitrous oxide; carbon dioxide; trifluoromethane (R32); trifluoroiodomethane; octafluoropropane (R218); 1,1,1,2,2-pentafluoroethane (R125); propane (R290); 1,1,1,2-tetrafluoropropene (HFO-1234yf); 1,2,3,3-tetrafluoro-2-propene (HFO-1234yc); 1,1,3,3-tetrafluoro-2-propene (HFO-1234zc); 1,1,1,3-tetrafluoro-2-propene (HFO-1234ze); 1,1,2,3-tetrafluoro-2-propene (HFO-1234ye); 1,1,1,2,3-pentafluoropropene (HFO-1225ye); 1,1,2,3,3-pentafluoropropene (HFO-1225yc); 1,1,1,3,3-pentafluoropropene (HFO-1225zc); (Z)1,1,1,3-tetrafluoropropene (HFO-1234zeZ); (Z)1,1,2,3-tetrafluoro-2-propene (HFO-1234yeZ); (E)1,1,1,3-tetrafluoropropene (HFO-1234zeE); (E)1,1,2,3-tetrafluoro-2-propene (HFO-1234yeE); (Z)1,1,1,2,3-pentafluoropropene (HFO-1225yeZ); (E)1,1,1,2,3-pentafluoropropene (HFO-1225yeE) and combinations of two or more of these; and optionally, an additive selected from the group consisting of stabilizers, metal passivators, corrosion inhibitors, and lubricants.
