TITLE OF THE INVENTIONCOMPOSITIONS COMPRISING TETRAFLUOROPROPENE AND USES THEREOFCROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of priority of U.S. Provisional Application 63 / 546,461 filed October 30, 2023, the disclosure of which is incorporated herein by reference it its entirety.FIELD
[0002] The present invention is directed to fluoroolefin refrigerant compositions, methods and systems using the same, and systems containing the E-HFO-1234ze refrigerant compositions.BACKGROUND
[0003] The fluorocarbon industry has been working for the past few decades to find replacement refrigerants for ozone depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) being phased out as a result of the Montreal Protocol. The solution for many applications has been the commercialization of hydrofluorocarbon (HFC) compounds for use as refrigerants, solvents, fire extinguishing agents, foam blowing agents and propellants. These new compounds, such as HFC-refrigerants, HFC-134a and HFC-125 being the most widely used at this time, have zero ozone depletion potential (ODP) and thus are not affected by the current regulatory phase -out as a result of the Montreal Protocol. In addition to ozone depleting concerns, global warming is another environmental concern in many applications. HFC refrigerants such as HFC-134a and HFC-125 respectively have global warming potentials (GWP) of 1,430 and 3,500 according to the UN’s IPCC Fourth Assessment Report (AR4).
[0004] This regulatory landscape is continuously evolving, taking into consideration properties beyond just ODP and GWP. More particularly, there is a need for refrigerants composition that not only meet low ODP standards and have lower (<500 GWP) or low (<150 GWP) global warming potentials, but that also exhibit low or no flammability, provide superior performance in a variety of applications and which meet the standards of evolving regulations.
[0005] There is a need in this art for new refrigerant compositions that meet evolving regulations as well as provide heat transfer and refrigerant characteristics that meet or exceed the effectiveness of conventional refrigerant and refrigerant blends.
[0006] HFO-1234ze(E) (CF3CH=CHF), like HFO-1234yf, has zero ozone depletion and very low global warming potential, and has thus been identified as a potential useful refrigerant. For example, U.S. Patent No. 7,862,742 discloses compositions comprising HFC-1234ze and HFO-1234yf. U.S. Patent No. 9,302,962 discloses methods for making HFO-1234ze. The disclosures of U.S. Patent No. 7,862,742 and U.S. Patent No. 9,302,962 are hereby incorporated by reference in their entireties. HFO-1234ze(E), which has zero ozone depletion and very low global warming potential and with a boiling point of -19.0 °C possesses physical properties that make it an attractive option for refrigeration, air conditioning, and heat pump applications.
[0007] The present invention solves certain problems associated with conventional refrigerants and provides HFO-1234ze(E)-based compositions which meet the evolving regulatory landscape.SUMMARY

[0047] A refrigerant is defined as a heat transfer fluid that undergoes a phase change from liquid to gas and back again during a cycle used to transfer of heat.
[0048] A heat transfer system is the system (or apparatus) used to produce a heating or cooling effect in a particular space. A heat transfer system may be a mobile system or a stationary system.
[0049] Examples of heat transfer systems are any type of refrigeration systems and air conditioning systems including, but are not limited to, stationary heat transfer systems, air conditioners, freezers, refrigerators, heat pumps, flooded evaporator heat pumps, direct expansion chillers heat pumps, chillers, flooded evaporator chillers, direct expansion chillers, walk-in coolers, mobile refrigerators, mobile heat transfer systems, mobile heat pumps, mobile air conditioning units, dehumidifiers, and combinations thereof.
[0050] Volumetric capacity is the amount of heat absorbed or rejected divided by the theoretical compressor displacement. Heat removed or absorbed is the enthalpy difference across a heat exchanger multiplied by the refrigerant mass flowrate. Theoretical compressor displacement is the refrigerant mass flowrate divided by the density of the gas entering the compressor (i.e., compressor suction density). More simply, volumetric capacity is the suction density multiplied by the heat exchanger enthalpy difference. Higher volumetric capacity allows the use of a smallercompressor for the same heat load. Herein, cooling capacity refers to the volumetric capacity in cooling mode and heating capacity refers to the volumetric capacity in heating mode.
[0051] Coefficient of performance (COP) is the amount of heat absorbed or rejected divided by the required energy input to operate the cycle (approximated by the compressor power). COP is specific to the mode of operation of a heat pump, thus COP for heating or COP for cooling. COP is directly related to the energy efficiency ratio (EER).
[0052] Subcooling refers to the reduction of the temperature of a liquid below that liquid’s saturation point for a given pressure. The liquid saturation point is the temperature at which the vapor is completely condensed to a liquid. By cooling a liquid below the saturation temperature (or bubble point temperature), the net refrigeration effect can be increased. Subcooling thereby improves refrigeration capacity and energy efficiency of a system. The subcool amount is the amount of cooling below the saturation temperature (in degrees).
[0053] Superheating refers to the increase of the temperature of a vapor above that vapor’s saturation point for a given pressure. The vapor saturation point is the temperature at which the liquid is completely evaporated to a vapor. Superheating continues to heat the vapor to a higher temperature vapor at the given pressure. By heating the vapor above the saturation temperature (or dew point temperature), the net refrigeration effect can be increased. Superheating thereby improves refrigeration capacity and energy efficiency of a system when it occurs in the evaporator. Suction line superheat does not add to the net refrigeration effect and can reduce efficiency and capacity. The superheat amount is the amount of heating above the saturation temperature (in degrees).
[0054] Temperature glide (sometimes referred to simply as "glide") is the absolute value of the difference between the starting and ending temperatures of a phasechange process by a refrigerant within a condenser of a refrigerant system, exclusive of any subcooling or superheating. For an evaporator, the glide is the difference in temperature between the dew point and the evaporator inlet. Glide may be used to describe condensation or evaporation of a near azeotrope or non-azeotropic composition. When referring to the temperature glide of an air conditioning or heatpump system, it is common to provide the average temperature glide being the average of the temperature glide in the evaporator and the temperature glide in the condenser. Glide is applicable to blend refrigerants, i.e. refrigerants that are composed of at least two components.
[0055] The net refrigeration effect is the quantity of heat that each kilogram of refrigerant absorbs in the evaporator to produce useful cooling.
[0056] The mass flow rate is the quantity of refrigerant in kilograms circulating through the refrigeration, heat pump or air conditioning system over a given period of time.
[0057] As used herein, the term “lubricant” means any material added to a composition or a compressor (and in contact with any heat transfer composition in use within any heat transfer system) that provides hydrodynamic lubrication to the compressor to aid in preventing parts from seizing.
[0058] Flammability is a term used to mean the ability of a composition to ignite and / or propagate a flame. For refrigerants and other heat transfer compositions, the lower flammability limit (“LFL”) is the minimum concentration of the heat transfer composition in air that is capable of propagating a flame through a homogeneous mixture of the composition and air under test conditions specified in ASTM (American Society of Testing and Materials) E681. The upper flammability limit (“UFL”) is the maximum concentration of the heat transfer composition in air that is capable of propagating a flame through a homogeneous mixture of the composition and air under the same test conditions. Determination of whether a refrigerant compound or mixture able to propagate a flame or not is also done by testing under the conditions of ASTM E-681.
[0059] During a refrigerant leak, the more volatile components of a mixture may leak preferentially. Thus, the composition in the system as well as the vapor leaking can vary over the time period of the leak. Thus, a non-flammable mixture may become able to propagate a flame under leakage scenarios. In order to be classified as non-flammable by ASH RAE (American Society of Heating, Refrigeration and Air- conditioning Engineers), a refrigerant or heat transfer composition must be nonflammable as formulated, but also under specified leakage conditions.
[0060] In order for a refrigerant to be classified by ANSI / ASHRAE as low flammability (class 2L), it must: 1) exhibit flame propagation when tested at 140°F (60°C) and 14.7 psia (101.3 kPa); 2) have an LFL >0.0062 lb / ft3(0.10 kg / m3); 3) have a heat of combustion <8169 Btu / lb (19,000 kJ / kg); and 4) have a maximum burning velocity of <3.9 in. / s (10 cm / s) when tested at 73.4°F (23.0°C) and 14.7 psia (101.3 kPa) in dry air.
[0061] In order for a refrigerant to be classified by ANSI / ASHRAE as flammable (class 2), it must: 1) exhibit flame propagation when tested at 140°F (60°C) and 14.7 psia (101.3 kPa); 2) have an LFL >0.0062 lb / ft3(0.10 kg / m3); and 3) have a heat of combustion <8169 Btu / lb (19,000 kJ / kg).
[0062] In order for a refrigerant to be classified by ANSI / ASHRAE standard 34 class 3, refrigerant 1) exhibits flame propagation when tested at 140°F (60°C) and 14.7 psia (101.3 kPa), 2) has an LFL < 0.0062 lb / ft3(0.10 kg / m3) or 3) has a heat of combustion >8169 Btu / lb (19,000 kJ / kg).
[0063] ASH RAE Standard 34 provides a methodology to calculate the heat of combustion for refrigerant blends using a balanced stoichiometric equation based on the complete combustion of one mole of refrigerant with enough oxygen for a stoichiometric reaction. Global warming potential (GWP) is an index for estimating relative global warming contribution due to atmospheric emission of a kilogram of a particular greenhouse gas compared to emission of a kilogram of carbon dioxide. GWP can be calculated for different time horizons showing the effect of atmospheric lifetime for a given gas. The GWP for the 100-year time horizon is commonly the value referenced. For mixtures, a weighted average can be calculated based on the individual GWPs for each component. Herein, the GWP values are those reported in the International Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) as those are the currently used values for several regulatory bodies
[0064] Ozone depletion potential (ODP) is a number that refers to the amount of ozone depletion caused by a substance. The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC-11 (fluorotrichloromethane). Thus, the ODP of CFC-11 is defined to be 1.0. Other CFCs and HCFCs have ODPs that range from 0.01 to 1.0. HFCs and HFOs havezero ODP because they do not contain chlorine, bromine or other ozone depleting halogens.
[0065] As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.
[0066] The transitional phrase "consisting of' excludes any element, step, or ingredient not specified. If in the claim such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase "consists of" appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.
[0067] The transitional phrase "consisting essentially of" is used to define a composition, method or apparatus that includes materials, steps, features, components, or elements, in addition to those literally disclosed provided that these additional included materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of’. Typically, components of the refrigerant mixtures and the refrigerant mixtures themselves can contain minor amounts (e.g., less than about 0.5 weight percent total) of impurities and / or byproducts (e.g., from the manufacture of the refrigerant components or reclamation of the refrigerant components from other systems) which do not materially affect the novel and basic characteristics of the refrigerant mixture.
[0068] Where applicants have defined an invention or a portion thereof with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such an invention using the terms “consisting essentially of’ or “consisting of.”
[0069] Also, use of “a” or “an” are employed to describe elements and components described herein. This is done merely for convenience and to give a general senseof the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise
[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the disclosed compositions, suitable methods and materials are described below. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety, unless a particular passage is cited. In case of conflict, the present specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting.COMPOSITIONS

[0153] In another embodiment, as used herein, “Group A Fluorinated Substances” includes any substance that has a Henry’s Law constant < 250 Pa*m3 / mol and contains at least one fully fluorinated methyl (-CF3) or methylene (-CF2-) carbon atom (without any H / CI / Br / l attached to it). In one embodiment, Group A Fluorinated Substances include, but are not limited to, TFA.
[0154] Thus, according to some embodiments, compositions of the present invention comprise HFO-1234ze(E), as a single fluid or blend, and are free of or substantially free of Group A Fluorinated Substances, such as TFA. In one embodiment, the phrase "free of" as used herein with respect to the presence of Group A Fluorinated Substances in the present compositions means that the amount of such substances in the compositions is sufficiently low so as to not be detectable, including but not limited to 0%, when measured by gas chromatography with a flame ionization detector, gas chromatography with a mass detector by analysis of a gas sample or liquid sample, and / or ion chromatography by analysis of a water sample after bubbling the thermal fluid through water. Such methodologies are well known to those skilled in the art. In one embodiment, the phrase "substantially free of" as used herein with respect to the presence of Group A Fluorinated Substances in the present compositions means that the amount of such substances in the compositions is > 0 wt.% and < 15 or wt.%, > 0 wt.% and < 10 wt.%, or > 0 wt.% and< 5 wt.%, or > 0 wt.% and < 4 wt.%, or > 0 wt.% and < 3 wt.%, or > 0 wt.% and< 2 wt.%, or > 0 wt.% and < 1 wt.%, and all values and ranges therebetween, when measured by gas chromatographic (GO) techniques, for example gas chromatography (GO) with a flame ionization or electron-capture detector, or GO coupled with a mass detector (gas chromatography / mass spectral (GC / MS) method), by ion chromatograph(IC) or ion chromatography mass spectrometry (IC-MS) techniques, or by high-performance liquid chromatography (HPLC) or high- performance liquid chromatography mass spectrometry (HPLC-MS) techniques. The TFA analytical standard may be used in either gas chromatography or ion chromatography and is available from, for example, Sigma Aldrich.
[0155] Further, in some embodiments, degradation products of such compositions of the present invention which comprise HFO-1234ze(E), as a single fluid or blend, are free of or substantially free of Group A Fluorinated Substances, such as TFA. In one embodiment, the phrase "free of" as used herein with respect to the formation ofGroup A Fluorinated Substances by the present compositions means that the theoretical molar yield of such substances in environmental compartments of air, soil / sediment and water produced during tropospheric degradation of the compositions is sufficiently low so as to not be detectable, including but not limited to 0%, when measured by GC techniques, for example GO with a flame ionization or electron-capture detector or GC / MS method, by IC or IC-MS techniques, or by HPLC or HPLC-MS techniques. In one embodiment, the phrase "substantially free of" as used herein with respect to the formation of Group A Fluorinated Substances by the present compositions means that the theoretical molar yield of such substances in environmental compartments of air, soil / sediment and water produced during tropospheric degradation of the compositions is > 0% and < 5%, or > 0% and < 4%, or > 0% and < 3%, or > 0% and < 2%, or > 0% and < 1%, and all values and ranges therebetween, when measured by GC techniques, for example GC with a flame ionization or electron-capture detector or GC / MS method, by IC or IC-MS techniques, or by HPLC or HPLC-MS techniques.
[0156] The presently disclosed compositions will perform more consistently and be more stable with only minor amounts of water present. Thus, the presently claimed compositions may further comprise less than 100 ppm (by weight) water, preferably less than 20 ppm (by weight) water, and even more preferably less than 10 ppm (by weight) water.
[0157] Additionally, the presently disclosed compositions will perform more consistently and be more stable with only minor amounts of oxygen or air present. Therefore, the presently claimed compositions may further comprise less than about 5 volume percent non-adsorbable gases (NAG), preferably less than 3 volume percent NAG, and more preferably less than 1.5 volume percent NAG. Further, the presently claimed compositions, due to the presence of air or NAG, will contain less than 1 volume percent oxygen, preferably less than 0.5 volume percent oxygen, and more preferably less than 0.3 volume percent oxygen.
[0158] In another embodiment, the presently disclosed compositions may contain a stabilizer. Such stabilizer compounds are intended to be present in a small amount and prevent decomposition due to the presence of water, air, NAG, or oxygen in a system while in use or while the composition is stored. HFO typerefrigerants, due to the presence of a double bond, may be subject to thermal instability and decompose under extreme use, handling or storage situations also. Therefore, there may be advantages to adding stabilizers to HFO type refrigerants. Stabilizers may notably include nitromethane, ascorbic acid, terephthalic acid, azoles such as tolutriazole or benzotriazole, phenolic compounds such as tocopherol, hydroquinone, t-butyl hydroquinone, 2,6-di-tertbutyl-4-methylphenol, epoxides (possibly fluorinated or perfluorinated alkyl epoxides or alkenyl or aromatic epoxides) such as n-butyl glycidyl ether, hexanediol diglycidyl ether, allyl glycidyl ether, butylphenylglycidyl ether, cyclic monoterpenes, terpenes, such as d-limonene, a- terpinene, p-terpinene, y-terpinene, a-pinene, or p-pinene, phosphites, phosphates, phosphonates, thiols and lactones. Examples of suitable stabilizers are disclosed in WO2019213004, WO2020222864, and WO2020222865; the disclosures of which are hereby incorporated by reference.
[0159] Blends may or may not include stabilizers depending on the requirements of the system being used. If the refrigerant blend does include a stabilizer, it may include any amount from 0.001 wt% up to 1 wt%, preferably from about 0.01 to about 0.5 weight percent, more preferably, from about 0.01 to about 0.3 weight percent of any of the stabilizers listed above.

[0171] Mouli et al. (WO 2008 / 027595 and WO 2009 / 042847) teach the use of alkyl silanes as a stabilizer in refrigerant compositions containing fluoroolefins.Phosphates, phosphites, epoxides, and phenolic additives also have been employed in certain refrigerant compositions. These are described for example by Kaneko (U.S. patent application Ser. No. 11 / 575,256, published as U.S. Publication 2007 / 0290164) and Singh et al. (U.S. patent application Ser.

[0177] Additionally, the present compositions may further comprise at least one inhibitor, and more particularly an effective amount of at least one inhibitor, and more particularly a polymerization inhibitor. More particularly, when the composition comprises a fluoroolefin, the composition preferably also comprises an effective amount of at least one inhibitor compound that inhibits, if not eliminates, the fluoroolefin from interacting with another compound and forming dimers, oligomers, homopolymers or polymeric products.
[0178] As described herein, the phrase “effective amount” refers to an amount of inhibitor of the present invention which, when added to a composition comprising at least one fluoroolefin, results in a composition wherein the fluoroolefin will not interact with an initiator, and / or degrade to produce as great a reduction in performance, for example, when in use in a cooling apparatus as compared to the composition without an inhibitor. For a cooling apparatus, such effective amounts of inhibitor may be determined by way of testing under the conditions of standard test ASHRAE 97-2007 (RA 2017). In a certain embodiment of the present invention, an effective amount may be said to be that amount of inhibitor which when combined with a composition comprising at least one fluoroolefin allows a cooling apparatus utilizing said composition comprising at least one fluoroolefin to perform at a comparable level of refrigeration performance and cooling capacity as if a composition comprising 1,1,1,2-tetrafluoroethane (R-134a), or other standard refrigerant (R-12, R-22, R-502, R-507A, R-508, R401A, R401 B, R402A, R402B, R408, R-410A, R-404A, R407C, R-413A, R-417A, R-422A, R-422B, R-422C, R-422D, R-423, R-114, R-11 , R-113, R-123, R-124, R236fa, or R-245fa) dependingupon what refrigerant may have been used in a similar system in the past, were being utilized as the working fluid.
[0179] The instant invention employs effective amounts of at least one of the foregoing inhibitors. While any suitable effective amount can be employed, effective amounts of the at least one inhibitor comprise from about 0.001 weight percent to about 10 weight percent, about 0.01 weight percent to about 5 weight percent, about 0.3 weight percent to about 4 weight percent, about 0.3 weight percent to about 1 weight percent, based on the total weight of compositions comprising at least one fluoroolefin as described herein. In one embodiment, an effective amount comprises about 1 to about 3,000 ppm by weight, or about 1 to about 2,000 ppm by weight, or about 10 to about 3,000 ppm by weight, or about 10 to about 2,000 ppm by weight, or about 30 ppm to about 3,000 ppm by weight, or about 30 ppm to about 2,000 ppm by weight, or about 5 to about 1,000 ppm and in some cases about 10 to about 500 ppm of at least one inhibitor based on the total weight of the composition. The amount of the inhibitor in the total composition can be reduced if an additional component which is added to an HFO-1234yf blend does not contain an inhibitor.
[0180] In one embodiment of the invention, the inventive compositions are substantially free of oligomeric products and polymeric products derived from a hydrofluoroolefin, such as HFO-1234yf, including but not limited to, oligomers and homopolymers. By “substantially free” it is meant that the composition contains less than about 1 wt.%, less than about 0.07 wt.%, less than about 0.03 wt.% and in some cases about 0 ppm of such products when measured by I R or NMR.
[0181] In some embodiments, the at least one inhibitor is selected from hydrocarbons such as cyclic monoterpenes (e.g., limonene, pinene, a-pinene, P-pinene, and terpinene); lipophilic organic compounds such as tocopherols (e.g., a-tocopherol) or butylated hydroxytoluene (BHT); phenols or aromatic organic compounds having at least one chemical moiety -C6H4(OH) (e.g., benzene-1 ,4-diol, 4-methoxyphenol); and mixtures thereof. Specific examples of inhibitor compounds may include at least one member selected from limonene (particularly D-limonene), a-terpinene, pinene, a-pinene, p-pinene, a-tocopherol, butylated hydroxytoluene (BHT), 4-methoxyphenol, benzene-1,4-diol, and mixtures thereof. In one embodiment, the inhibitor is limonene, particularly D-limonene.
[0182] Additional details regarding properties of suitable inhibitors can be found in International Application Nos. WO 2019 / 213004, WO 2020 / 222864 and WO2023 / 141098, the entire disclosure of each of which is incorporated herein in its entirety.
[0183] The compositions of the present invention may be prepared by any convenient method to combine the desired amount 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. In one embodiment, the composition according to the present invention can be prepared by blending HFO-1234zeE and H FC- 152a, and, in some cases, at least one of the additional compounds. In another embodiment, any of the foregoing refrigerant compositions can be prepared by blending HFO-1234zeE, HFC-152a, at least one compound selected from HFC-227ea, HFO-1336mzz(E), HFC-134, HFC- 125, HFC-32, HFC-134a, HCFO-1224yd(Z), and, in some cases, at least one of the additional compounds. Further, any of the above-mentioned additives, such as stabilizers, acid scavengers, flame suppressants, tracers and the like, may be blended with the HFO-1234zeE and HFC-152a containing compositions.
[0184] In a further embodiment, the compositions may be prepared from recycled or reclaimed refrigerant. One or more of the components may be recycled or reclaimed by means of removing contaminants, such as air, water, or residue, which may include lubricant or particulate residue from system components. The means of removing the contaminants may vary widely, but can include distillation, decantation, filtration, and / or drying by use of molecular sieves or other absorbents. Then the recycled or reclaimed component(s) may be combined with the other component(s) as describe above.METHODS, APPARATUS AND SYSTEMS

These may include, but are not limited to, supermarket and convenience store refrigerated cases for beverages, dairy, and produce and prepared foods. In one embodiment, the refrigeration system is a low or medium temperature refrigeration system, including supermarket and convenience store refrigerator and freezer cabinets and displays, ice machines, self-contained coolers and freezers, such as beverage coolers, walk-in and reach-incoolers and freezers, supermarket rack and distributed systems, and refrigerated or frozen food transport.
[0189] In one embodiment, the air conditioner may be a residential, commercial, or industrial air-conditioning system. These may include, but are not limited to, window, ducted, ductless, packaged terminal, and those exterior to, but connected to the building, such as rooftop systems. These may also include residential heat pumps that provide comfort air-conditioning and heating.
[0190] In another embodiment, the cooling may be performed in a chiller. Chillers, including both flooded evaporator and direct expansion chillers, may be coupled with an air handling and distribution system to provide comfort air conditioning (cooling and dehumidifying the air) to large commercial buildings, including hotels, office buildings, hospitals, universities and the like. In another embodiment, chillers, most likely air-cooled direct expansion chillers, have found additional utility in naval submarines and surface vessels.
[0191] Chillers may be characterized by the compressor used. In one embodiment, the chiller may comprise a centrifugal compressor. In another embodiment, the chiller may comprise a scroll compressor. In another embodiment the chiller may comprise a screw compressor. In yet another embodiment, the chiller may comprise a reciprocating compressor.
[0192] The present method for cooling may be particularly useful in high ambient temperature regions, due to the high critical temperature of blends comprising, consisting of, or consisting essentially of HFO-1234zeE, HFC-152a, and at least on compounds selected from the group consisting of HFC-227ea, HFO-1336mzz(E), HFC-134, HFC-125, HFC-32, HFC-134a, HCFO-1224yd(Z).
[0193] In another embodiment, the method for producing cooling is particularly useful in regions where the ambient temperature can exceed at least 35°C.
[0194] In geographic areas with high ambient temperatures, where air conditioning becomes essential, refrigerant compositions with high critical temperatures and high thermal stability are desirable. Currently available hydrofluorocarbon (HFC) refrigerants such as R-410A, R-407C or R-32 have relatively low critical temperatures. As a consequence, these refrigerants do not perform well in extremehot environments. The energy efficiency of a refrigerant generally decreases as the condensing temperature approaches the refrigerant critical temperature during operation at high ambient temperatures. In hot climates, R-22 has remained the refrigerant of choice for much air conditioning and refrigeration applications as it is not flammable and has a higher critical temperature so that it delivers higher cooling capacity and higher energy efficiency in hot climates as compared to R-410A or R- 32. However, R-22 is an ozone depleting substance in the Montreal Protocol to reduce ozone depletion. As such, R-22 has been mandated and legislated for phase out for manufacture for and use in air conditioning and refrigeration. There is interest in finding a refrigerant with the lowest possible direct GWP and also that performs well in hot climate (or high ambient) temperature regions.
[0195] In the method for producing cooling the body to be cooled may be defined as any space, location, object, or body for which it is desirable to provide cooling. Examples include spaces, open or enclosed, that require cooling such as a residence, such as an apartment or apartment building, university dormitory, townhouse or other attached house, or a single-family home; or the body to be cooled may be any other building, such as an office building, supermarket, college or university classroom or administration buildings.
[0196] In another embodiment, a method for producing air conditioning in high ambient temperatures is provided. The method comprises evaporating the inventive composition and thereafter condensing said composition. The method is particularly useful in regions where ambient temperatures can exceed 35°C or more.
[0197] In another embodiment, a method is provided for replacing HCFC-22 in high ambient air conditioning apparatus comprising providing the inventive composition to said apparatus. The method of replacing HCFC-22 is particularly useful in regions where ambient temperatures can exceed 35°C or more.
[0198] Similarly, in some industrial air conditioning applications heat must be released in high ambient temperature environments. HCFC-124 has been used as the working fluid in such applications. HCFC-124 is also controlled under the Montreal protocol as an ozone depleting substance and more environmentally sustainable replacements are desirable. Thus, a method is provided for replacing HCFC-124 in industrial air conditioning apparatus, comprising providing the inventivecomposition to said apparatus. The method of replacing HCFC-124 is particularly useful in regions where ambient temperatures can exceed 35°C or more.
[0199] In another embodiment, the method for producing cooling and method for replacing HCFC-22 or HCFC-124 are useful for systems operating in ambient temperatures of 40°C or higher.

In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures of 55°C or higher. In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures of 60°C or higher. In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures from 35-50°C. In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures from 35-60°C.

In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures from 45-60°C. In another embodiment, the method for producing cooling is useful for systems operating in ambient temperatures from 50-60°C.
[0200] In another embodiment, provided is a method of heating comprising evaporating the inventive composition and thereafter condensing said composition in the vicinity of a body to be heated.
[0201] In one embodiment, the heating is accomplished by a heat pump, which may be a residential, light commercial, commercial, or industrial heat pump system. These may include, but are not limited to, residential heat pumps that provide comfort air-conditioning and heating, hot water heat pumps for heating air (by secondary loop) or for heating water for residential or commercial use, heat pumps for heating manufacturing process equipment, and high temperature heat pumps (with condensing temperature of 50 deg C or higher).
[0202] Due to the high critical temperature of the inventive composition, and more particularly of blends comprising, consisting of, or consisting essentially of HFO-1234zeE, HFC-152a, and at least one compound selected from HFC-227ea, HFO- 1336mzz(E), HFC-134, HFC-125, HFC-32, HFC-134a, and H CFO-1224yd (Z), it is possible to heat water to higher temperatures than propane or R-454C.

In one embodiment, the refrigeration system is a low or medium temperature refrigeration system, including supermarket and convenience store refrigerator and freezer cabinets and displays, ice machines, self-contained coolers and freezers, such as beverage coolers, walk-in and reach-in coolers and freezers, supermarket rack and distributed systems, and refrigerated or frozen food transport.
[0206] In one embodiment, the air conditioner may be a residential, commercial, or industrial air-conditioning system.

In another embodiment the chiller may comprise a screw compressor. In yet another embodiment, the chiller may comprise a reciprocating compressor. When replacing a refrigerant in a chiller, the compressor, often designed for the refrigerant to be used, may need modification. Therefore, for centrifugal chillers, the impeller diameter or impeller tip speed for the new refrigerant must be similar or match that for the original refrigerant to be used as a drop-in replacement.
[0210] In another embodiment, the system containing the inventive composition may be an automobile heat pump for cooling and heating the passenger compartment of an electric or hybrid vehicle. Electric or hybrid vehicles include automobiles with no internal combustion engine (ICE) or those that maintain an ICE but also use electric power and are therefore hybrid electric vehicles (HEV) or plug-in hybrid electric vehicles (PHEV) or mild hybrid electric vehicles (MHEV). Additionally, electric or hybrid vehicles include full electric vehicles (EV), such as battery electric vehicles (BEV). All of these electric or hybrid vehicles use at least one electric motor, wherein the electric motor provides some form of propulsion for the vehicles normally provided by the ICE found in gasoline / diesel powered vehicles.
[0211] In one embodiment, the automobile heat pump is a secondary loop system. The secondary loop allows the separation of a flammable refrigerant from the passenger compartment, using a heat transfer fluid to produce cooling or heating in the passenger compartment.
[0212] In another embodiment, the automobile heat pump does not include a positive temperature coefficient (PTC) heater. The PTC heater often used in electric vehicles is needed in the absence of an ICE to provide adequate heating to the passenger compartment.
[0213] In another embodiment, the inventive composition may be used in a method of replacing at least one of R-22, HFC-134a, propane, HFO-1234yf, R-407C, R-404A, R-410A, R-513A, R-454A, R-454B, R-454C, R-448A, R-449A, R-449B, R- 449C, R-1234zeE, R-515B, R471A, R-476A, R-482A, R-452A, or R-452C, in refrigeration, air-conditioning, heat pump, or chiller systems comprising providing any of the compositions disclosed herein to the system in place of R-22, HFC-134a, propane, HFO-1234yf, R-407C, R-404A, R-410A, R-513A, R-454A, R-454B, R- 454C, R-448A, R-449A, R-449B, R-449C, R-1234zeE, R-515B, R471A, R-476A, R- 482A, R-452A, or R-452C.

[0227] With respect to hydrocarbons, the present blowing agent compositions may include in certain preferred embodiments, for example, iso, normal and / or cyclopentane for thermoset foams and butane or isobutane for thermoplastic foams.

[0228] The relative amount of any of the above noted additional co-blowing agents, as well as any additional components which may be included in presentcompositions, can vary widely within the general broad scope of the present invention according to the particular application for the composition, and all such relative amounts are considered to be within the scope hereof.
[0229] In certain embodiments, it is preferred that the blowing agent compositions of the present invention comprise at least one co-blowing agent and an amount of HFO-1234ze(E) and HFC-152a sufficient to produce a blowing agent composition which is overall nonflammable.
[0230] For compositions which include HFC co-blowing agents, the HFC coblowing agent (preferably C2, C3, C4 and / or C5 HFC), and even more preferably difluoroethane (HFC-152a being particularly preferred for extruded thermoplastics) and / or pentafluoropropane (HFC-245)), is preferably present in the composition in amounts of from about 5% by weight to about 80% by weight of the total blowing agent composition, more preferably from about 10% by weight to about 75% by weight, and even more preferably of from about 25% to about 75% by weight of the total blowing agent. Furthermore, in such embodiments, the HFC is preferably C2-C4 HFC, and even more preferably C3 HFC, with penta-fluorinated C3 HFC, such as HFC-245fa, being highly preferred in certain embodiments.
[0231] One embodiment of the present invention provides foamable compositions. As is known to those skilled in the art, foamable compositions generally include one or more components capable of forming foam. As used herein, the term “foam foaming agent’ is used to refer to a component, or a combination on components, which are capable of forming a foam structure, preferably a generally cellular foam structure. The foamable compositions of the present invention include such component(s) and the blowing agent composition of the present invention (e.g., composition comprising at least HFO-1234ze(E) and HFC-152a).
[0232] In certain embodiments, the one or more components capable of forming foam comprise a thermosetting composition capable of forming foam and / or foamable compositions. Examples of thermosetting compositions include polyurethane and polyisocyanurate foam compositions, and also phenolic foam compositions. This reaction and foaming process may be enhanced through the use of various additives such as catalysts and surfactant materials that serve to control and adjust cell size and to stabilize the foam structure during formation. Furthermore,it is contemplated that any one or more of the additional components described above with respect to the blowing agent compositions of the present invention could be incorporated into the foamable composition of the present invention. In such thermosetting foam embodiments, one or more of the present compositions are included as or part of a blowing agent in a foamable composition, or as a part of a two or more part foamable composition, which preferably includes one or more of the components capable of reacting and / or foaming under the proper conditions to form a foam or cellular structure.
[0233] In certain other embodiments of the present invention, the one or more components capable of foaming comprise thermoplastic materials, particularly thermoplastic polymers and / or resins. Examples of thermoplastic foam components include polyolefins, such as for example monovinyl aromatic compounds of the formula Ar — CH=CH2 wherein Ar is an aromatic hydrocarbon radical of the benzene series such as polystyrene (PS). Other examples of suitable polyolefin resins in accordance with the invention include the various ethylene resins including the ethylene homopolymers such as polyethylene and ethylene copolymers, polypropylene (PP) and polyethylene-terephthalate (PET). In certain embodiments, the thermoplastic foamable composition is an extrudable composition.
[0234] It is contemplated that all presently known and available methods and systems for forming foam are readily adaptable for use in connection with the present invention. For example, the methods of the present invention generally require incorporating a blowing agent in accordance with the present invention into a foamable or foam forming composition and then foaming the composition, preferably by a step or series of steps which include causing volumetric expansion of the blowing agent in accordance with the present invention.
[0235] In general, it is contemplated that the presently used systems and devices for incorporation of blowing agent and for foaming are readily adaptable for use in accordance with the present invention. In fact, it is believed that one advantage of the present invention is the provision of an improved blowing agent which is generally compatible with existing foaming methods and systems.
[0236] Thus, it will be appreciated by those skilled in the art that the present invention comprises methods and systems for foaming all types of foams, includingthermosetting foams, thermoplastic foams and formed-in-place foams. Thus, one aspect of the present invention is the use of the present blowing agents in connection with conventional foaming equipment, such as polyurethane foaming equipment, at conventional processing conditions. The present methods therefore include polyol premix type operations, blending type operations, third stream blowing agent addition, and blowing agent addition at the foam head.
[0237] With respect to thermoplastic foams, the preferred methods generally comprise introducing a blowing agent in accordance with the present invention into a thermoplastic material, preferably thermoplastic polymer such as polyolefin, and then subjecting the thermoplastic material to conditions effective to cause foaming. For example, the step of introducing the blowing agent into the thermoplastic material may comprise introducing the blowing agent into a screw extruder containing the thermoplastic, and the step of causing foaming may comprise lowering the pressure on the thermoplastic material and thereby causing expansion of the blowing agent and contributing to the foaming of the material.
[0238] One embodiment of the present invention relates to methods of forming foams, especially panel foams and spray foams, and preferably such foams made from polyurethane and polyisocyanurate. The methods generally comprise providing a blowing agent composition of the present inventions, adding (directly or indirectly) the blowing agent composition to a foamable composition, and reacting the foamable composition under the conditions effective to form a foam or cellular structure, as is well known in the art. 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.
[0239] In general, such preferred methods comprise preparing polyurethane or polyisocyanurate foams by combining an isocyanate, a polyol or mixture of polyols, a blowing agent or mixture of blowing agents comprising one or more of the present compositions, and other materials such as catalysts, surfactants, and optionally, flame retardants, colorants, or other additives.
[0240] It is convenient in many applications to provide the components for polyurethane or polyisocyanurate foams in pre-blended formulations. Most typically, the foam formulation is pre-blended into two components. The isocyanate and optionally certain surfactants and blowing agents comprise the first component, commonly referred to as the “A” component. The polyol or polyol mixture, surfactant, catalysts, blowing agents, flame retardant, and other isocyanate reactive components comprise the second component, commonly referred to as the “B” component. Accordingly, polyurethane or polyisocyanurate foams are readily prepared by bringing together the A and B side components either by hand mix for small preparations and, preferably, machine mix techniques to form blocks, slabs, laminates, pour-in-place panels and other items, spray applied foams, froths, and the like. Optionally, other ingredients such as fire retardants, colorants, auxiliary blowing agents, and even other polyols can be added as one or more additional streams to the mix head or reaction site.
