Abstract:
Compositions and methods comprising one or more compounds according to Formula I: where R1, R2 and R3 are each independently CxR'(2x+1)-yHy; each R' is independently selected from F or Cl and wherein the value of (2x+1)-y is the total number of R' substituents on the indicated carbon atom(s); each x is independently equal to or greater than 1 and equal to or less than 6; and y is equal to or greater than 0 and less than or equal to 2x+1, provided that the total number of R' present in the compound is 6 or greater, and that the compound has from zero up to two (2) Cl substituents.
Abstract:
Heat pipes and low-pressure working fluids used for heat pipes are described, by charging the low pressure working fluids with a level of non-condensable gases of less than 1% by volume, and the heat pipes can provide better thermal performance than aluminium plates while little or no additional cost is introduced for degassing.

Abstract:
The present invention relates to a refrigerant composition, including difluoromethane (HFC- 32), pentafluoroethane (HFC-125), and trifluoroiodomethane (CF 3 I) 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.
Abstract:
Disclosed are cascade refrigerant systems for providing cooling of air located in an enclosure that is occupied by or which will be exposed to humans or other animals during normal use, wherein systems includes; (1) a first, relatively low temperature heat transfer circuit having a first evaporator located within the enclosure and a first heat transfer fluid in the low temperature heat transfer circuit; (2) a second heat transfer circuit located substantially outside the enclosure comprising a second heat transfer fluid; (3) a heat exchanger which serves as the condenser in the low temperature circuit thermally coupled with the high temperature circuit by virtue of rejecting heat into the second heat transfer fluid; and (4) in the high temperature loop of a heat exchanger which transfers heat from the second heat transfer fluid exiting from a high temperature condenser to the portion of the second heat transfer fluid which is traveling to the suction side of the compressor.
Abstract:
Disclosed are methods and compositions for forming a flexible, open cell foams which utilize a thermosetting composition comprising one or more components capable of forming a thermoset matrix and a blowing agent comprising at least one chemical blowing agent, such as water, and at least one physical blowing agent includes at least one of HFO-1336mzz, HFO-1438mzz (preferably E-HFO-1438mzz) and HFO-1447fz, to form a flexible foam.
Abstract:
