Abstract

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a tetrafluoropropene and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

Claims (9)

1. A composition comprising HFO-1234yf, HFC-32, HFC-125, and HFC-134a; wherein the composition comprises from about 15 weight percent to about 40 weight percent HFO-1234yf, from about 20 weight percent to about 40 weight percent HFC-32, from about 15 weight percent to about 40 weight percent HFC-125, and from about 20 weight percent to about 40 weight percent HFC-134a.

2. The composition of claim 1 further comprising at least one lubricant selected from the group consisting of mineral oils, alkylbenzenes, synthetic paraffins, synthetic naphthenes, poly alpha olefins, polyalkylene glycols, dibasic acid esters, polyesters, neopentyl esters, polyvinyl ethers, silicones, silicate esters, fluorinated compounds, phosphate esters and mixtures thereof.

3. A process to produce cooling comprising condensing a composition of claim 1 and thereafter evaporating said composition in the vicinity of a body to be cooled.

4. A process to produce heat comprising condensing the composition of claim 1 in the vicinity of a body to be heated and thereafter evaporating said composition.

5. A method for replacing R22, R404A, or R507A in a system that uses, used or was designed to use R22, R404A, or R507A, wherein said method comprises providing the composition of claim 1 to said system.

6. A refrigeration, air-conditioning or heat pump apparatus containing the composition of claim 1 .

7. A stationary air conditioning apparatus containing the composition of claim 1 .

8. A stationary refrigeration system containing the composition of claim 1 .

9. A stationary heat pump system containing the composition of claim 1 .
