Azeotrope-like compositions of tetrafluoropropene and hydrofluorocarbons

A method for heating an article comprising:

• condensing, in the vicinity of the article to be heated, a refrigerant composition comprising an azeotrope-like composition comprising effective amounts of trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze) and a compound selected from the group consisting of 1,1,1,2,3,3,3-heptafluoropropane (“HFC-227ea”) 1,1,1,2-tetrafluoroethane (“HFC-134a”), 1,1,1,2,2-pentafluoroethane (“HFC-125”) and combinations of two or more of these;
• and
• thereafter evaporating said refrigerant composition.

A method of recharging a refrigerant system that contains a refrigerant to be replaced and a lubricant comprising:

• removing the refrigerant to be replaced from the refrigeration system while retaining a substantial portion of the lubricant in said system;
• and
• introducing into the system an azeotrope-like refrigerant comprising effective amounts of trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze) and a compound selected from the group consisting of 1,1,1,2,3,3,3-heptafluoropropane (“HFC-227ea”) 1,1,1,2-tetrafluoroethane (“HFC-134a”), 1,1,1,2,2-pentafluoroethane (“HFC-125”) and combinations of two or more of these.

A method of preparing a foam comprising:

• providing a foamable composition comprising (a) at least one foamable component and (b) a blowing agent comprising an azeotrope-like mixture consisting essentially of trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze) and a compound selected from the group consisting of 1,1-difluoroethane (“HFC-152a”), 1,1,1,2,3,3,3-heptafluoropropane (“HFC-227ea”), 1,1,1,2-tetrafluoroethane (“HFC-134a”), 1,1,1,2,2-pentafluoroethane (“HFC-125”) and combinations of two or more of these;
• and
• reacting said foamable composition to form a foam.
