BACKGROUND OF THE INVENTION 1. Field of the Invention. The present invention relates to compositions for use in refrigeration, air conditioning, and heat pump systems wherein the composition comprises a fluoroolefin 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. 2. Description of Related Art. The refrigeration industry has been working for the past few decades to find replacement refrigerants for the ozone depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) being phased out as a result of the Montreal Protocol. The solution for most refrigerant producers has been the commercialization of hydrofluorocarbon (HFC) refrigerants. The new HFC refrigerants, HFC-134a being the most widely used at this time, have zero ozone depletion potential and thus are not affected by the current regulatory phase out as a result of the Montreal Protocol. Further environmental regulations may ultimately cause global phase out of certain HFC refrigerants. Currently, the automobile industry is facing regulations relating to global warming potential for refrigerants used in mobile air conditioning. Therefore, there is a great current need to identify new refrigerants with reduced global warming potential for the mobile air-conditioning market. Should the regulations be more broadly applied in the future, an even greater need will be felt for refrigerants that can be used in all areas of the refrigeration and air-conditioning industry. Currently proposed replacement refrigerants for HFC-134a include HFC-152a, pure hydrocarbons such as butane or propane, or "natural" refrigerants such as C02. Many of these suggested replacements are toxic, flammable, and/or have low .o energy efficiency. Therefore, new alternative refrigerants are being sought. An aspect of the present invention is to provide novel refrigerant compositions and heat transfer fluid compositions that provide unique characteristics to meet the demands of low or zero ozone depletion potential and lower global warming potential as compared to current refrigerants. .5 BRIEF SUMMARY OF THE INVENTION The present invention relates to a composition comprising HFC-1225ye and at least one compound selected from the group consisting of: HFC-1234ze, HFC-1234yf, HFC-1234ye, HFC-1243zf, HFC-32, HFC-125, HFC-134, HFC-134a, HFC-143a, HFC-152a, HFC-161, HFC-227ea, HFC-236ea, HFC-236fa, HFC-245fa, HFC-365mfc, propane, n-butane, isobutane, 2-methylbutane, n-pentane, cyclopentane, dimethylether, CF3SCF3, C02 and CF31.

The most preferred compositions of the present invention listed in Table 2 are generally expected to maintain the desired properties and functionality when the components are present in the concentrations as listed +/- 2 weight percent. The compositions containing C02 would be expected to maintain the desired properties and functionality when the C02 was present at the listed concentration +/- 0.2 weight percent. The compositions of the present invention may be azeotropic or near azeotropic compositions. By azeotropic composition is meant a constant-boiling mixture of two or more substances that behave as a single substance. One way to characterize an azeotropic composition is that the vapor produced by partial evaporation or distillation of the liquid has the same composition as the liquid from which it is evaporated or distilled, i.e., the mixture distills/refluxes without compositional change. Constant-boiling compositions are characterized as azeotropic because they exhibit either a maximum or minimum boiling point, as compared with that of the non-azeotropic mixture of the same compounds. An azeotropic composition will not fractionate within a refrigeration or air conditioning system during operation, which may reduce efficiency of the system. Additionally, an azeotropic composition will not fractionate upon leakage from a refrigeration or air conditioning system. In the situation where one component of a mixture is flammable, fractionation during leakage could lead to a flammable composition either within the system or outside of the system. A near-azeotropic composition (also commonly referred to as an "azeotrope-like composition") is a substantially constant boiling liquid admixture of two or more substances that behaves essentially as a single substance. One way to characterize a near-azeotropic composition is that the vapor produced by partial evaporation or distillation of the liquid has substantially the same composition as the liquid from which it was evaporated or distilled, that is, the admixture distills/refluxes without substantial composition change. Another way to characterize a near- azeotropic composition is that the bubble point vapor pressure and the dew point vapor pressure of the composition at a particular temperature are substantially the same. Herein, a composition is near azeotropic if, after 50 weight percent of the composition is removed, such as by evaporation or boiling off, the difference in vapor pressure between the original

9n composition and the composition remaining after 50 weight percent of the original composition has been removed is less than about 10 percent. Azeotropic compositions of the present invention at a specified temperature are shown in Table 3.

Certain of the compositions of the present invention are non azeotropic compositions. Those compositions of the present invention falling within the preferred ranges of Table 2, but outside of the near-azeotropic ranges of Table 5 and Table 6 may be considered to be non-azeotropic. A non-azeotropic composition may have certain advantages over azetropic or near azeotropic mixtures. A non-azeotropic composition is a mixture of two or more substances that behaves as a mixture rather than a single substance. One way to characterize a non-azeotropic composition is that the vapor produced by partial evaporation or distillation of the liquid has a substantially different composition as the liquid from which it was evaporated or distilled, that is, the admixture distills/refluxes with substantial composition change. Another way to characterize a non- azeotropic composition is that the bubble point vapor pressure and the dew point vapor pressure of the composition at a particular temperature are substantially different. Herein, a composition is non-azeotropic if, after 50 weight percent of the composition is removed, such as by evaporation or boiling off, the difference in vapor pressure between the original composition and the composition remaining after 50 weight percent of the original composition has been removed is greater than about 10 percent. The compositions of the present invention may be prepared by any convenient method to combine the desired amounts of the individual components. A preferred method is to weigh the desired component amounts and thereafter combine the components in an appropriate vessel. Agitation may be used, if desired. An alternative means for making compositions of the present invention may be a method for making a refrigerant blend composition, wherein said refrigerant blend composition comprises a composition as disclosed herein, said method comprising (i) reclaiming a volume of one or more components of a refrigerant composition from at least one refrigerant container, (ii) removing impurities sufficiently to enable reuse of said one or more of the reclaimed components, (iii) and optionally, combining all or part of said reclaimed volume of components with at least one additional refrigerant composition or component. A refrigerant container may be any container in which is stored a refrigerant blend composition that has been used in a refrigeration apparatus, air-conditioning apparatus or heat pump apparatus. Said refrigerant container may be the refrigeration apparatus, air-conditioning apparatus or heat pump apparatus in which the refrigerant blend was used. Additionally, the refrigerant container may be a storage container for collecting reclaimed refrigerant blend components, including but not limited to pressurized gas cylinders. Residual refrigerant means any amount of refrigerant blend or refrigerant blend component that may be moved out of the refrigerant container by any method known for transferring refrigerant blends or refrigerant blend components. Impurities may be any component that is in the refrigerant blend or refrigerant blend component due to its use in a refrigeration apparatus, air conditioning apparatus or heat pump apparatus. Such impurities include but are not limited to refrigeration lubricants, being those described earlier herein, particulates including but not limited to metal, metal salt or elastomer particles, that may have come out of the refrigeration apparatus, air-conditioning apparatus or heat pump apparatus, and any other contaminants that may adversely effect the performance of the refrigerant blend composition. Such impurities may be removed sufficiently to allow reuse of the refrigerant blend or refrigerant blend component without adversely effecting the performance or equipment within which the refrigerant blend or refrigerant blend component will be used. It may be necessary to provide additional refrigerant blend or refrigerant blend component to the residual refrigerant blend or refrigerant blend component in order to produce a composition that meets the specifications q1 required for a given product. For instance, if a refrigerant blend has 3 components in a particular weight percentage range, it may be necessary to add one or more of the components in a given amount in order to restore the composition to within the specification limits. Compositions of the present invention have zero or low ozone depletion potential and low global warming potential (GWP). Additionally, the compositions of the present invention will have global warming potentials that are less than many hydrofluorocarbon refrigerants currently in use. One aspect of the present invention is to provide a refrigerant with a global warming potential ofless than 1000, less than 500, less than 150, less than 100, or less than 50. Another aspect of the present invention is to reduce the net GWP of refrigerant mixtures by adding fluoroolefins to said mixtures. The compositions of the present invention may be useful as low global warming potential (GWP) replacements for currently used refrigerants, including but not limited to R134a (or HFC-134a, 1,1,1,2-tetrafluoroethane), R22 (or HCFC-22, chlorodifluoromethane), R123 (or HFC-123, 2,2-dichloro-1,1,1 trifluoroethane), R11 (CFC-11, fluorotrichloromethane), R12 (CFC-12, dichlorodifluoromethane), R245fa (or HFC-245fa, 1,1,1,3,3 pentafluoropropane), R114 (or CFC-114, 1,2-dichloro-1,1,2,2 tetrafluoroethane), R236fa (or HFC-236fa, 1,1,1,3,3,3-hexafluoropropane), R124 (or HCFC-124, 2-chloro-1,1,1,2-tetrafluoroethane), R407C (ASHRAE designation for a blend of 52 weight percent R134a, 25 weight percent R125 (pentafluoroethane), and 23 weight percent R32 (difluoromethane), R410A (ASHRAE designation for a blend of 50 weight percent R125 and 50 weight percent R32), R417A, (ASHRAE designation for a blend of 46.6 weight percent R125, 50.0 weight percent R134a, and 3.4 weight percent n-butane), R422A (ASHRAE designation for a blend of 85.1 weight percent R125, 11.5 weight percent R134a, and 3.4 weight percent isobutane), R404A, (ASHRAE designation for a blend of 44 weight percent R125, 52 weight percent R143a (1,1,1-trifluoroethane), and 4.0 weight percent R134a) and R507A (ASHRAE designation for a blend of 50 weight percent R125 and 50 weight percent R143a). Additionally, the compositions of the present invention may be useful as replacements for R12 (CFC-12, dichlorodifluoromethane) or R502 (ASHRAE designation for a blend of 51.2 weight percent CFC-115 (chloropentafluoroethane) and 48.8 weight percent HCFC-22). Often replacement refrigerants are most useful if capable of being used in the original refrigeration equipment designed for a different refrigerant. The compositions of the present invention may be useful as replacements for the above-mentioned refrigerants in original equipment. Additionally, the compositions of the present invention may be useful as replacements for the above mentioned refrigerants in equipment designed to use the above mentioned refrigerants. The compositions of the present invention may further comprise a lubricant. Lubricants of the present invention comprise refrigeration lubricants, i.e. those lubricants suitable for use with refrigeration, air-conditioning, or heat pump apparatus. Among these lubricants are those conventionally used in compression refrigeration apparatus utilizing chlorofluorocarbon refrigerants. Such lubricants and their properties are discussed in the 1990 ASHRAE Handbook, Refrigeration Systems and Applications, chapter 8, titled "Lubricants in Refrigeration Systems", pages 8.1 through 8.21. Lubricants of the present invention may comprise those commonly known as "mineral oils" in the field of compression refrigeration lubrication. Mineral oils comprise paraffins (i.e. straight-chain and branched-carbon-chain, saturated hydrocarbons), naphthenes (i.e. cyclic paraffins) and aromatics (i.e. unsaturated, cyclic hydrocarbons containing one or more rings characterized by alternating double bonds). Lubricants of the present invention further comprise those commonly known as "synthetic oils" in the field of compression refrigeration lubrication. Synthetic oils comprise alkylaryls (i.e. linear and branched alkyl alkylbenzenes), synthetic paraffins and napthenes, and poly(alphaolefins). Representative conventional lubricants of the present invention are the commercially available BVM 100 N (paraffinic mineral oil sold by BVA Oils), Suniso@ 3GS and Suniso@ 5GS (naphthenic mineral oil sold by Crompton Co.), Sontex@ 372LT (naphthenic mineral oil sold by Pennzoil), Calumet@ RO-30 (naphthenic mineral oil sold by Calumet Lubricants), Zerol@ 75, Zerol@ 150 and Zerol@ 500 (linear alkylbenzenes sold by Shrieve Chemicals) and HAB 22 (branched alkylbenzene sold by Nippon Oil). Lubricants of the present invention further comprise those that have been designed for use with hydrofluorocarbon refrigerants and are miscible with refrigerants of the present invention under compression refrigeration, air conditioning, or heat pump apparatus' operating conditions. Such lubricants and their properties are discussed in "Synthetic Lubricants and High Performance Fluids", R. L. Shubkin, editor, Marcel Dekker, 1993. Such lubricants include, but are not limited to, polyol esters (POEs) such as Castrol@

100 (Castrol, United Kingdom), polyalkylene glycols (PAGs) such as RL-488A from Dow (Dow Chemical, Midland, Michigan), and polyvinyl ethers (PVEs). These lubricants are readily available from various commercial sources. Lubricants of the present invention are selected by considering a given compressor's requirements and the environment to which the lubricant will be exposed. Lubricants of the present invention preferably have a kinematic viscosity of at least about 5 cs (centistokes) at 400 C. Commonly used refrigeration system additives may optionally be added, as desired, to compositions of the present invention in order to enhance lubricity and system stability. These additives are generally known within the field of refrigeration compressor lubrication, and include anti wear agents, extreme pressure lubricants, corrosion and oxidation inhibitors, metal surface deactivators, free radical scavengers, foaming and antifoam control agents, leak detectants and the like. In general, these additives are present only in small amounts relative to the overall lubricant composition. They are typically used at concentrations of from less than about 0.1 % to as much as about 3 % of each additive. These additives are selected on the basis of the individual system requirements. Some typical examples of such additives may include, but are not limited to, lubrication enhancing additives, such as alkyl or aryl esters of phosphoric acid and of thiophosphates. Additionally, the metal dialkyl dithiophosphates (e.g. zinc dialkyl dithiophosphate or ZDDP, Lubrizol 1375) and other members of this family of chemicals may be used in compositions of the present invention. Other antiwear additives include natural product oils and assymetrical polyhydroxyl lubrication additives such as Synergol TMS (International Lubricants). Similarly, stabilizers such as anti oxidants, free radical scavengers, and water scavengers may be employed. Compounds in this category can include, but are not limited to, butylated hydroxy toluene (BHT) and epoxides. The compositions of the present invention may further comprise about 0.01 weight percent to about 5 weight percent of an additive such as, for example, a stabilizer, free radical scavenger and/or antioxidant. Such additives include but are not limited to, nitromethane, hindered phenols, hydroxylamines, thiols, phosphites, or lactones. Single additives or combinations may be used. The compositions of the present invention may further comprise about 0.01 weight percent to about 5 weight percent of a water scavenger (drying compound). Such water scavengers may comprise ortho esters such as trimethyl-, triethyl-, or tripropylortho formate.

The compositions of the present invention may further comprise a tracer selected from the group consisting of hydrofluorocarbons (HFCs), deuterated hydrocarbons, deuterated hydrofluorocarbons, perfluorocarbons, fluoroethers, brominated compounds, iodated compounds, alcohols, aldehydes, ketones, nitrous oxide (N20) and combinations thereof. The tracer compounds are added to the compositions in previously determined quantities to allow detection of any dilution, contamination or other alteration of the composition, as described in U. S. Patent application serial no. 11/062044, filed February 18, 2005. Typical tracer compounds for use in the present compositions are listed in Table 7.

The compounds listed in Table 7 are available commercially (from chemical supply houses) or may be prepared by processes known in the art. Single tracer compounds may be used in combination with a refrigeration/heating fluid in the compositions of the present invention or multiple tracer compounds may be combined in any proportion to serve as a tracer blend. The tracer blend may contain multiple tracer compounds from the same class of compounds or multiple tracer compounds from different classes of compounds. For example, a tracer blend may contain 2 or more deuterated hydrofluorocarbons, or one deuterated hydrofluorocarbon in combination with one or more perfluorocarbons. Additionally, some of the compounds in Table 7 exist as multiple isomers, structural or optical. Single isomers or multiple isomers of the same compound may be used in any proportion to prepare the tracer compound. Further, single or multiple isomers of a given compound may be combined in any proportion with any number of other compounds to serve as a tracer blend.

The tracer compound or tracer blend may be present in the compositions at a total concentration of about 50 parts per million by weight (ppm) to about 1000 ppm. Preferably, the tracer compound or tracer blend is present at a total concentration of about 50 ppm to about 500 ppm and most preferably, the tracer compound or tracer blend is present at a total concentration of about 100 ppm to about 300 ppm. The compositions of the present invention may further comprise a compatibilizer selected from the group consisting of polyoxyalkylene glycol ethers, amides, nitriles, ketones, chlorocarbons, esters, lactones, aryl ethers, fluoroethers and 1,1,1-trifluoroalkanes. The compatibilizer is used to improve solubility of hydrofluorocarbon refrigerants in conventional refrigeration lubricants. Refrigeration lubricants are needed to lubricate the compressor of a refrigeration, air-conditioning or heat pump apparatus. The lubricant must move throughout the apparatus with the refrigerant in particular it must return from the non-compressor zones to the compressor to continue to function as lubricant and avoid compressor failure. Hydrofluorocarbon refrigerants are generally not compatible with convention refrigeration lubricants such as mineral oils, alkylbenzenes, synthetic paraffins, synthetic napthenes and poly(alpha)olefins. Many replacement lubricants have been proposed, however, the polyalkylene glycols, polyol esters and polyvinyl ethers, suggested for use with hydrofluorocarbon refrigerants are expensive and absorb water readily. Water in a refrigeration, air-conditioning system or heat pump can lead to corrosion and the formation of particles that may plug the capillary tubes and other small orifices in the system, ultimately causing system failure. Additionally, in existing equipment, time consuming and costly flushing procedures are required to change to a new lubricant. Therefore, it is desirable to continue to use the original lubricant if possible. The compatibilizers of the present invention improve solubility of the hydrofluorocarbon refrigerants in conventional refrigeration lubricants and thus improve oil return to the compressor.

Hydrocarbon ether solubilizing agents of the present invention comprise ethers containing only carbon, hydrogen and oxygen, such as dimethyl ether (DME). Solubilizing agents of the present invention may be present as a single compound, or may be present as a mixture of more than one solubilizing agent. Mixtures of solubilizing agents may contain two solubilizing agents from the same class of compounds, say two lactones, or two solubilizing agents from two different classes, such as a lactone and a polyoxyalkylene glycol ether. In the present compositions comprising refrigerant and UV fluorescent dye, or comprising heat transfer fluid and UV fluorescent dye, from about 0.001 weight percent to about 1.0 weight percent of the composition is UV dye, preferably from about 0.005 weight percent to about 0.5 weight percent, and most preferably from 0.01 weight percent to about 0.25 weight percent.

Solubilizing agents such as ketones may have an objectionable odor, which can be masked by addition of an odor masking agent or fragrance. Typical examples of odor masking agents or fragrances may include Evergreen, Fresh Lemon, Cherry, Cinnamon, Peppermint, Floral or Orange Peel all commercially available, as well as d-limonene and pinene. Such odor masking agents may be used at concentrations of from about 0.001% to as much as about 15% by weight based on the combined weight of odor masking agent and solubilizing agent. Solubility of these UV fluorescent dyes in the compositions of the present invention may be poor. Therefore, methods for introducing these dyes into the refrigeration, air-conditioning, or heat pump apparatus have been awkward, costly and time consuming. US patent no. RE 36,951 describes a method, which utilizes a dye powder, solid pellet or slurry of dye that may be inserted into a component of the refrigeration, air-conditioning, or heat pump apparatus. As refrigerant and lubricant are circulated through the apparatus, the dye is dissolved or dispersed and carried throughout the apparatus. Numerous other methods for introducing dye into a refrigeration or air conditioning apparatus are described in the literature. Ideally, the UV fluorescent dye could be dissolved in the refrigerant itself thereby not requiring any specialized method for introduction to the refrigeration, air conditioning apparatus, or heat pump. The present invention relates to compositions including UV fluorescent dye, which may be introduced into the system as a solution in the refrigerant. The inventive compositions will allow the storage and transport of dye-containing compositions even at low temperatures while maintaining the dye in solution. In the present compositions comprising refrigerant, UV fluorescent dye and solubilizing agent, or comprising heat transfer fluid and UV fluorescent dye and solubilizing agent, from about 1 to about 50 weight percent, preferably from about 2 to about 25 weight percent, and most preferably from about 5 to about 15 weight percent of the combined composition is solubilizing agent. In the compositions of the present invention the UV fluorescent dye is present in a concentration from about 0.001 weight percent to about 1.0 weight percent, preferably from 0.005 weight percent to about 0.5 weight percent, and most preferably from 0.01 weight percent to about 0.25 weight percent. The present invention further relates to a method of using the compositions further comprising ultraviolet fluorescent dye, and optionally, solubilizing agent, in refrigeration, air-conditioning, or heat pump apparatus.

The method comprises introducing the composition into the refrigeration, air conditioning, or heat pump apparatus. This may be done by dissolving the UV fluorescent dye in the composition in the presence of a solubilizing agent and introducing the combination into the apparatus. Alternatively, this may be done by combining solubilizing agent and UV fluorescent dye and introducing said combination into refrigeration or air-conditioning apparatus containing refrigerant and/or heat transfer fluid. The resulting composition may be used in the refrigeration, air-conditioning, or heat pump apparatus. The present invention further relates to a method of using the compositions comprising ultraviolet fluorescent dye to detect leaks. The presence of the dye in the compositions allows for detection of leaking refrigerant in a refrigeration, air-conditioning, or heat pump apparatus. Leak detection helps to address, resolve or prevent inefficient operation of the apparatus or system or equipment failure. Leak detection also helps one contain chemicals used in the operation of the apparatus. The method comprises providing the composition comprising refrigerant, ultra-violet fluorescent dye, as described herein, and optionally, a solubilizing agent as described herein, to refrigeration, air-conditioning, or heat pump apparatus and employing a suitable means for detecting the UV fluorescent dye-containing refrigerant. Suitable means for detecting the dye include, but are not limited to, ultra-violet lamps, often referred to as a "black light" or "blue light". Such ultra-violet lamps are commercially available from numerous sources specifically designed for this purpose. Once the ultra-violet fluorescent dye containing composition has been introduced to the refrigeration, air conditioning, or heat pump apparatus and has been allowed to circulate throughout the system, a leak can be found by shining said ultra-violet lamp on the apparatus and observing the fluorescence of the dye in the vicinity of any leak point. The present invention further relates to a method for replacing a high GWP refrigerant in a refrigeration, air-conditioning, or heat pump apparatus, wherein said high GWP refrigerant is selected from the group consisting of R134a, R22, R245fa, R114, R236fa, R124, R41OA, R407C, R417A, R422A, R507A, and R404A,, said method comprising providing a composition of the present invention to said refrigeration, air-conditioning, or heat pump apparatus that uses, used or is designed to use said high GWP refrigerant. Vapor-compression refrigeration, air-conditioning, or heat pump systems include an evaporator, a compressor, a condenser, and an expansion device. A vapor-compression cycle re-uses refrigerant in multiple steps producing a cooling effect in one step and a heating effect in a different step. The cycle can be described simply as follows. Liquid refrigerant enters an evaporator through an expansion device, and the liquid refrigerant boils in the evaporator at a low temperature to form a gas and produce cooling. The low-pressure gas enters a compressor where the gas is compressed to raise its pressure and temperature. The higher-pressure (compressed) gaseous refrigerant then enters the condenser in which the refrigerant condenses and discharges its heat to the environment. The refrigerant returns to the expansion device through which the liquid expands from the higher-pressure level in the condenser to the low pressure level in the evaporator, thus repeating the cycle. As used herein, mobile refrigeration apparatus or mobile air-conditioning apparatus refers to any refrigeration or air-conditioning apparatus incorporated into a transportation unit for the road, rail, sea or air. In addition, apparatus, which are meant to provide refrigeration or air-conditioning for a system independent of any moving carrier, known as "intermodal" systems, are included in the present invention. Such intermodal systems include "containers" (combined sea/land transport) as well as "swap bodies" (combined road and rail transport). The present invention is particularly useful for road transport refrigerating or air-conditioning apparatus, such as automobile air-conditioning apparatus or refrigerated road transport equipment. The present invention further relates to a process for producing cooling comprising evaporating the compositions of the present invention in the vicinity of a body to be cooled, and thereafter condensing said compositions. The present invention further relates to a process for producing heat comprising condensing the compositions of the present invention in the vicinity of a body to be heated, and thereafter evaporating said compositions. The present invention further relates to a refrigeration, air-conditioning, or heat pump apparatus containing a composition of the present invention wherein said composition at least one fluoroolefin. The present invention further relates to a mobile air-conditioning apparatus containing a composition of the present invention wherein said composition comprises at least one fluoroolefin. The present invention further relates to a method for early detection of a refrigerant leak in a refrigeration, air-conditioning or heat pump apparatus said method comprising using a non-azeotropic composition in said apparatus, and monitoring for a reduction in cooling performance. The non-azeotropic compositions will fractionate upon leakage from a refrigeration, air-conditioning or heat pump apparatus and the lower boiling (higher vapor pressure) component will leak out of the apparatus first. When this occurs, if the lower boiling component in that composition provides the majority of the refrigeration capacity, there will be a marked reduction in the capacity and thus performance of the apparatus. In an automobile air-conditioning system, as an example, the passengers in the automobile will detect a reduction in the cooling capability of the system. This reduction in cooling capability can be interpreted to mean that refrigerant is being leaked and that the system requires repair. The present invention further relates to a method of using the compositions of the present invention as a heat transfer fluid composition, said process comprising transporting said composition from a heat source to a heat sink. Heat transfer fluids are utilized to transfer, move or remove heat from one space, location, object or body to a different space, location, object or body by radiation, conduction, or convection. A heat transfer fluid may function as a secondary coolant by providing means of transfer for cooling (or heating) from a remote refrigeration (or heating) system. In some systems, the heat transfer fluid may remain in a constant state throughout the transfer process (i.e., not evaporate or condense). Alternatively, evaporative cooling processes may utilize heat transfer fluids as well. A heat source may be defined as any space, location, object or body from which it is desirable to transfer, move or remove heat. Examples of heat sources may be spaces (open or enclosed) requiring refrigeration or cooling, such as refrigerator or freezer cases in a supermarket, building spaces requiring air-conditioning, or the passenger compartment of an automobile requiring air conditioning. A heat sink may be defined as any space, location, object or body capable of absorbing heat. A vapor compression refrigeration system is one example of such a heat sink. In another embodiment, the present invention relates to blowing agent compositions comprising the fluoroolefin-containing compositions as described herein for use in preparing foams. In other embodiments the invention provides foamable compositions, and preferably polyurethane and polyisocyanate foam compositions, and method of preparing foams. In such foam embodiments, one or more of the present fluoroolefin-containing compositions are included as a blowing agent in foamable compositions, which composition preferably includes one or more additional components capable of reacting and foaming under the proper conditions to form a foam or cellular structure. Any of the methods well known in the art, such as those described in "Polyurethanes Chemistry and Technology," Volumes I and II, Saunders and Frisch, 1962, John Wiley and Sons, New York, N.Y., which is incorporated herein by reference, may be used or adapted for use in accordance with the foam embodiments of the present invention. The present invention further relates to a method of forming a foam comprising: (a) adding to a foamable composition a fluoroolefin-containing composition of the present invention; and (b) reacting the foamable composition under conditions effective to form a foam. Another embodiment of the present invention relates to the use of the fluoroolefin-containing compositions as described herein for use as propellants in sprayable compositions. Additionally, the present invention relates to a sprayable composition comprising the fluoroolefin-containing compositions as described herein. The active ingredient to be sprayed together with inert ingredients, solvents and other materials may also be present in a sprayable composition. Preferably, the sprayable composition is an aerosol. Suitable active materials to be sprayed include, without limitations, cosmetic materials, such as deodorants, perfumes, hair sprays, cleaners, and polishing agents as well as medicinal materials such as anti-asthma and anti-halitosis medications. The present invention further relates to a process for producing aerosol products comprising the step of adding a fluoroolefin-containing composition as described herein to active ingredients in an aerosol container, wherein said composition functions as a propellant. A further aspect provides methods of suppressing a flame, said methods comprising contacting a flame with a fluid comprising a fluoroolefin containing composition of the present disclosure. Any suitable methods for contacting the flame with the present composition may be used. For example, a fluoroolefin-containing composition of the present disclosure may be sprayed, poured, and the like onto the flame, or at least a portion of the flame may be immersed in the flame suppression composition. In light of the teachings herein, those of skill in the art will be readily able to adapt a variety of conventional apparatus and methods of flame suppression for use in the present disclosure. A further embodiment provides methods of extinguishing or suppressing a fire in a total-flood application comprising providing an agent comprising a fluoroolefin-containing composition of the present disclosure; disposing the agent in a pressurized discharge system; and discharging the agent into an area to extinguish or suppress fires in that area. Another embodiment provides methods of inerting an area to prevent a fire or explosion comprising providing an agent comprising a fluoroolefin-containing composition of the present disclosure; disposing the agent in a pressurized discharge system; and discharging the agent into the area to prevent a fire or explosion from occurring. The term "extinguishment" is usually used to denote complete elimination of a fire; whereas, "suppression" is often used to denote reduction, but not necessarily total elimination, of a fire or explosion. As used herein, terms "extinguishment" and "suppression" will be used interchangeably. There are four general types of halocarbon fire and explosion protection applications. (1) In total-flood fire extinguishment and/or suppression applications, the agent is discharged into a space to achieve a concentration sufficient to extinguish or suppress an existing fire. Total flooding use includes protection of enclosed, potentially occupied spaces such, as computer rooms as well as specialized, often unoccupied spaces such as aircraft engine nacelles and engine compartments in vehicles. (2) In streaming applications, the agent is applied directly onto a fire or into the region of a fire. This is usually accomplished using manually operated wheeled or portable units. A second method, included as a streaming application, uses a "localized" system, which discharges agent toward a fire from one or more fixed nozzles. Localized systems may be activated either manually or automatically. (3) In explosion suppression, a fluoroolefin-containing composition of the present disclosure is discharged to suppress an explosion that has already been initiated. The term "suppression" is normally used in this application because the explosion is usually self-limiting. However, the use of this term does not necessarily imply that the explosion is not extinguished by the agent. In this application, a detector is usually used to detect an expanding fireball from an explosion, and the agent is discharged rapidly to suppress the explosion. Explosion suppression is used primarily, but not solely, in defense applications. (4) In inertion, a fluoroolefin-containing composition of the present disclosure is discharged into a space to prevent an explosion or a fire from being initiated. Often, a system similar or identical to that used for total-flood fire extinguishment or suppression is used. Usually, the presence of a dangerous condition (for example, dangerous concentrations of flammable or explosive gases) is detected, and the fluoroolefin-containing composition of the present disclosure is then discharged to prevent the explosion or fire from occurring until the condition can be remedied. The extinguishing method can be carried out by introducing the composition into an enclosed area surrounding a fire. Any of the known methods of introduction can be utilized provided that appropriate quantities of the composition are metered into the enclosed area at appropriate intervals. For example, a composition can be introduced by streaming, e.g., using conventional portable (or fixed) fire extinguishing equipment; by misting; or by flooding, e.g., by releasing (using appropriate piping, valves, and controls) the composition into an enclosed area surrounding a fire. The composition can optionally be combined with an inert propellant, e.g., nitrogen, argon, decomposition products of glycidyl azide polymers or carbon dioxide, to increase the rate of discharge of the composition from the streaming or flooding equipment utilized. Preferably, the extinguishing process involves introducing a fluoroolefin-containing composition of the present disclosure to a fire or flame in an amount sufficient to extinguish the fire or flame. One skilled in this field will recognize that the amount of flame suppressant needed to extinguish a particular fire will depend upon the nature and extent of the hazard. When the flame suppressant is to be introduced by flooding, cup burner test data is useful in determining the amount or concentration of flame suppressant required to extinguish a particular type and size of fire. Laboratory tests useful for determining effective concentration ranges of fluoroolefin-containing compositions when used in conjunction with extinguishing or suppressing a fire in a total-flood application or fire inertion are described, for example, in U.S. Patent No. 5,759,430, which is hereby incorporated by reference. Where the terms "comprise", "comprises", "comprised" or comprising" are used in this specification, they are to be interpreted as specifying the presence of the stated features, integers, steps or components referred to, but not to preclude the presence or addition of one or more other feature, integer, step, component or group thereof.

EXAMPLES

EXAMPLE 1 Impact of vapor leakage A vessel is charged with an initial composition at a temperature of either -25 °C or if specified, at 25 °C, and the initial vapor pressure of the composition is measured. The composition is allowed to leak from the vessel, while the temperature is held constant, until 50 weight percent of the initial composition is removed, at which time the vapor pressure of the composition remaining in the vessel is measured. Results are shown in Table 9.

Several compositions have even higher energy efficiency (COP) than HFC-134a while maintaining lower discharge pressures and temperatures. Capacity for the present compositions is also similar to R134a indicating these could be replacement refrigerants for R134a in refrigeration and air conditioning, and in mobile air-conditioning applications in particular. Those compositions containing hydrocarbon may also improve oil solubility with conventional mineral oil and alkyl benzene lubricants.

EXAMPLE 6 Flammability Flammable compounds may be identified by testing under ASTM (American Society of Testing and Materials) E681-01, with an electronic ignition source. Such tests of flammability were conducted on HFC-1234yf, HFC 1225ye and a mixture of the present disclosure at 101 kPa (14.7 psia), 100 °C

(212 °F), and 50 percent relative humidity, at various concentrations in air in order to determine the lower flammability limit (LFL) and upper flammability limit (UFL). The results are given in Table 13.

JRA

TABLE 14 Composition LFL (vol % in air) UFL (vol % in air) HFC-1225ye Non-flammable Non-flammable (100 wt%) HFC-1234yf 5.0 14.5 (100 wt%) HFC 1234yf/1225ye 8.5 12.0 (50/50 wt%) HFC 1234yf/1225ye Non-flammable Non-flammable (40/60 wt%)

The results indicate that while HFC-1234yf is flammable, addition of HFC-1225ye reduces the flammability. Therefore, compositions comprising about 1 weight percent to about 49 weight percent HFC-1234yf and about 99 weight percent to about 51 weight percent HFC-1225ye are preferred.
