Abstract

Disclosed are methods of transferring heat to or from a fluid or body comprising causing heat to be transferred to or from a composition comprising at least trans-1,3,3,3-tetrafluorpropene.

Claims

1. A method of transferring heat to or from a body comprising causing heat to be transferred to or from a composition comprising at least trans-1,3,3,3-tetrafluorpropene and into or from said body by heat transfer contact between said composition and the body.

2. The method of claim 1 wherein said composition comprises at least about 90% by weight of trans-1,3,3,3-tetrafluorpropene.

3. The method of claim 1 wherein said composition comprises from about 5% by weight to about 99% by weight of said trans-1,3,3,3-tetrafluorpropene.

4. The method of claim 1 wherein said composition comprises from about 5% by weight to about 95% by weight of said trans-1,3,3,3-tetrafluorpropene.

5. The method of claim 1 wherein said composition further comprises lubricant.

6. The method of claim 5 wherein said lubricant is present in the composition in an amount of from about 30 to about 50 percent by weight of the composition.

7. The method of claim 1 wherein said composition further comprises at least one co-heat transfer agent.

8. The method of claim 7 wherein said co-heat transfer agent is selected from the group consisting of:

trichlorofluoromethane (CFC-11);

dichlorodifluoromethane (CFC-12);

difluoromethane (HFC-32);

pentafluoroethane (HFC-125);

1,1,2,2-tetrafluoroethane (HFC-134);

1,1,1,2-tetrafluoroethane (HFC-134a);

difluoroethane (HFC-152a);

1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea);

1,1,1,3,3,3-hexafluoropropane (HFC-236fa);

1,1,1,3,3-pentafluoropropane (HFC-245fa);

1,1,1,3,3-pentafluorobutane (HFC-365mfc);

water;

CO2 and combinations of two or more of these.

9. A method of cooling a body by transferring heat from the body to a heat transfer fluid, the method comprising;

(a) providing a heat transfer fluid comprising at least one trans-1,3,3,3-tetrafluorpropene in a gas phase at a first pressure and at a first temperature;

(b) removing heat from said fluid provided at said first temperature by condensing at least a portion of said heat transfer fluid to produce at least a portion of said heat transfer fluid in a liquid phase at about said first pressure;

(c) reducing the pressure of at least a portion of said liquid heat transfer fluid from step (b) to produce a heat transfer fluid at a second temperature substantially below said first temperature and a second pressure substantially below said first pressure;

(d) cooling the body by bringing said body into heat transfer contact with said heat transfer fluid at about said second temperature produced in step (c); and

(e) providing at least a portion of said fluid at said first pressure in said step (a) by compressing said heat transfer fluid provided in step (d) from about said second pressure to about said first pressure.

10. The method of claim 9 wherein said heat transfer contact of step (d) comprises evaporating said heat transfer fluid.

11. The method of claim 9 wherein said composition comprises at least about 90% by weight of trans-1,3,3,3-tetrafluorpropene.

12. The method of claim 9 wherein said composition comprises from about 5% by weight to about 99% by weight of trans-1,3,3,3-tetrafluorpropene.

13. A chiller system using the method of claim 9.

14. A heat pump using the method of claim 9.

15. A method of cooling a body by transferring heat from the body to a heat transfer fluid, the method comprising;

(a) providing a heat transfer fluid comprising trans-1,3,3,3-tetrafluorpropene and a lubricant;

(b) compressing said heat transfer fluid to produce a heat transfer fluid comprising at least a portion of said trans-1,3,3,3-tetrafluorpropene at a first pressure and at a first temperature;

(c) removing heat from said fluid provided at said first temperature by step (b) by condensing at least a portion of said heat transfer fluid to produce at least a portion of said heat transfer fluid in a liquid phase at about said first pressure;

(d) reducing the pressure of at least a portion of said liquid heat transfer fluid from step (c) to produce a heat transfer fluid at a second temperature substantially below said first temperature and a second pressure substantially below said first pressure;

(e) cooling the body by evaporating by heat transfer contact with the body at least a portion of said heat transfer fluid produced at said second temperature in step (d); and

(f) providing at least a portion of said fluid at said first pressure in said step (a) by compressing said evaporated heat transfer fluid provided in step (e) from about said second pressure to about said first pressure.

16. The method of claim 15 wherein said composition comprises at least about 50% by weight of trans-1,3,3,3-tetrafluorpropene.

17. The method of claim 15 wherein said composition comprises at least about 70% by weight of trans-1,3,3,3-tetrafluorpropene.
