Heat transfer methods
Various compositions, including particularly aerosol compositions, containing fluorinated olefins, including particularly tetra- and penta-fluorpropenes, in a variety of applications are disclosed.
1. A method for evaporative cooling comprising:
(a) bringing a cosmetic composition comprising 1-chloro,3,3,3-trifluoropropene (HFCO-1233zd) into contact, either directly or indirectly, with a body to be cooled by evaporative cooling; and
(b) thereafter evaporating said HFCO-1233zd by absorbing heat from said body.
2. The method of claim 1 wherein said HFCO-1233zd comprises transHFCO-1233zd.
3. The method of claim 1 wherein said HFCO-1233zd consists essentially of transHFCO-1233zd.
4. The method of claim 1 wherein said HFCO-1233zd consists of transHFCO-1233zd.
5. The method of claim 1 wherein said cosmetic composition further comprises a cleaning solvent.
6. The method of claim 1 wherein said cosmetic composition further comprises a perfume.
7. The method of claim 1 wherein said cosmetic composition further comprises a deodorant.
8. The method of claim 1 wherein said cosmetic composition further comprises propane.
9. The method of claim 1 wherein said cosmetic composition further comprises 1,3,3,3-tetrafluoropropene (HFO-1234ze).
10. The method of claim 1 wherein said cosmetic composition further comprises trans-1,3,3,3-tetrafluoropropene (transHFO-1234ze).
11. The method of claim 1 wherein said cosmetic composition further comprises 2,3,3,3-tetrafluoropropene (HFO-1234yf).
12. The method of claim 1 wherein said cosmetic composition further comprises 1,1,1,3,3-petafluoropropane (HFC-245fa).
13. The method of claim 1 wherein said bringing step comprises spraying said composition onto said body.
14. The method of claim 13 wherein said composition is an aerosol.
