Description

HEAT TRANSFER COMPOSITIONS

The invention relates to heat transfer compositions, and in particular to heat transfer compositions which may be suitable as replacements for existing refrigerants such as R- 134a, R-152a, R-1234yf, R-22, R-410A, R-407A, R-407B, R-407C, R507 and R-404a.

The listing or discussion of a prior-published document or any background in the specification should not necessarily be taken as an acknowledgement that a document or background is part of the state of the art or is common general knowledge.

Mechanical refrigeration systems and related heat transfer devices such as heat pumps and air-conditioning systems are well known. In such systems, a refrigerant liquid evaporates at low pressure taking heat from the surrounding zone. The resulting vapour is then compressed and passed to a condenser where it condenses and gives off heat to a second zone, the condensate being returned through an expansion valve to the evaporator, so completing the cycle. Mechanical energy required for compressing the vapour and pumping the liquid is provided by, for example, an electric motor or an internal combustion engine.

In addition to having a suitable boiling point and a high latent heat of vaporisation, the properties preferred in a refrigerant include low toxicity, non-flammability, non-corrosivity, high stability and freedom from objectionable odour. Other desirable properties are ready compressibility at pressures below 25 bars, low discharge temperature on compression, high refrigeration capacity, high efficiency (high coefficient of performance) and an evaporator pressure in excess of 1 bar at the desired evaporation temperature.

Dichlorodifluoromethane (refrigerant R-12) possesses a suitable combination of properties and was for many years the most widely used refrigerant. Due to international concern that fully and partially halogenated chlorofluorocarbons were damaging the earth's protective ozone layer, there was general agreement that their manufacture and use should be severely restricted and eventually phased out completely. The use of dichlorodifluoromethane was phased out in the 1990's.

Chlorodifluoromethane (R-22) was introduced as a replacement for R-12 because of its lower ozone depletion potential. Following concerns that R-22 is a potent greenhouse gas, its use is also being phased out.

Whilst heat transfer devices of the type to which the present invention relates are essentially closed systems, loss of refrigerant to the atmosphere can occur due to leakage during operation of the equipment or during maintenance procedures. It is important, therefore, to replace fully and partially halogenated chiorofluorocarbon refrigerants by materials having zero ozone depletion potentials.

In addition to the possibility of ozone depletion, it has been suggested that significant concentrations of halocarbon refrigerants in the atmosphere might contribute to global warming (the so-called greenhouse effect). It is desirable, therefore, to use refrigerants which have relatively short atmospheric lifetimes as a result of their ability to react with other atmospheric constituents such as hydroxyl radicals, or as a result of ready degradation through photolytic processes.

R-410A and R-407 refrigerants (including R-407A, R-407B and R-407C) have been introduced as a replacement refrigerant for R-22. However, R-22, R-41 OA and the R-407 refrigerants all have a high global warming potential (GWP, also known as greenhouse warming potential).

1,1,1,2-tetrafluoroethane (refrigerant R-134a) was introduced as a replacement refrigerant for R-12. R-134a is an energy efficient refrigerant, used currently for automotive air conditioning. However it is a greenhouse gas with a GWP of 1430 relative to 002 (GWP of 002 is 1 by definition). The proportion of the overall environmental impact of automotive air conditioning systems using this gas, which may be attributed to the direct emission of the refrigerant, is typically in the range 10-20%. Legislation has now been passed in the European Union to rule out use of refrigerants having GWP of greater than 150 for new models of car from 2011. The car industry operates global technology platforms, and in any event emission of greenhouse gas has global impact, thus there is a need to find fluids having reduced environmental impact (e.g. reduced GWP) compared to HFC-134a.

R-152a (1,1-difluoroethane) has been identified as an alternative to R-134a. It is somewhat more efficient than R-134a and has a greenhouse warming potential of 120.

However the flammability of R-152a is judged too high, for example to permit its safe use in mobile air conditioning systems. In particular it is believed that its lower flammable limit in air is too low, its flame speeds are too high, and its ignition energy is too low.

Thus there is a need to provide alternative refrigerants having improved properties such as low flammability. Fluorocarbon combustion chemistry is complex and unpredictable.

It is not always the case that mixing a non-flammable fluorocarbon with a flammable fluorocarbon reduces the flammability of the fluid or reduces the range of flammable compositions in air. For example, the inventors have found that if non-flammable R-134a is mixed with flammable R-152a, the lower flammable limit of the mixture alters in a manner which is not predictable. The situation is rendered even more complex and less predictable if ternary or quaternary compositions are considered.

There is also a need to provide alternative refrigerants that may be used in existing devices such as refrigeration devices with little or no modification.

R-1234yf (2,3,3,3-tetrafluoropropene) has been identified as a candidate alternative refrigerant to replace R-134a in certain applications, notably the mobile air conditioning or heat pumping applications. Its GWP is about 4. R-1234yf is flammable but its flammability characteristics are generally regarded as acceptable for some applications including mobile air conditioning or heat pumping. In particular, when compared with R- 152a, its lower flammable limit is higher, its minimum ignition energy is higher and the flame speed in air is significantly lower than that of R-152a.

The environmental impact of operating an air conditioning or refrigeration system, in terms of the emissions of greenhouse gases, should be considered with reference not only to the so-called "direct" GWP of the refrigerant, but also with reference to the so-called "indirect" emissions, meaning those emissions of carbon dioxide resulting from consumption of electricity or fuel to operate the system. Several metrics of this total GWP impact have been developed, including those known as Total Equivalent Warming Impact (TEWI) analysis, or Life-Cycle Carbon Production (LCCP) analysis. Both of these measures include estimation of the effect of refrigerant GWP and energy efficiency on overall warming impact. Emissions of carbon dioxide associated with manufacture of the refrigerant and system equipment should also be considered.

The energy efficiency and refrigeration capacity of R-1234yf have been found to be significantly lower than those of R-134a and in addition the fluid has been found to exhibit increased pressure drop in system pipework and heat exchangers. A consequence of this is that to use R-1234yf and achieve energy efficiency and cooling performance equivalent to R-134a, increased complexity of equipment and increased size of pipework is required, leading to an increase in indirect emissions associated with equipment. Furthermore, the production of R-1234yf is thought to be more complex and less efficient in its use of raw materials (fluorinated and chlorinated) than R-134a.

Current projections of long term pricing for R-1234yf is in the range 10-20 times greater than R-134a. This price differential and the need for extra expenditure on hardware will limit the rate at which refrigerants are changed and hence limit the rate at which the overall environmental impact of refrigeration or air conditioning may be reduced. In summary, the adoption of R-1234yf to replace R-134a will consume more raw materials and result in more indirect emissions of greenhouse gases than does R-134a.

Some existing technologies designed for R-134a may not be able to accept even the reduced flammability of some heat transfer compositions (any composition having a GWP of less than 150 is believed to be flammable to some extent).

A principal object of the present invention is therefore to provide a heat transfer composition which is usable in its own right or suitable as a replacement for existing refrigeration usages which should have a reduced GWP, yet have a capacity and energy efficiency (which may be conveniently expressed as the "Coefficient of Performance") ideally within 10% of the values, for example of those attained using existing refrigerants (e.g. R-134a, R-152a, R-1234yf, R-22, R-410A, R-407A, R-407B, R-407C, R507 and R- 404a), and preferably within less than 10% (e.g. about 5%) of these values. It is known in the art that differences of this order between fluids are usually resolvable by redesign of equipment and system operational features. The composition should also ideally have reduced toxicity and acceptable flammability.

The subject invention addresses the above deficiencies by the provision of a heat transfer composition comprising (i) a first component selected from trans-i,3,3,3-tetrafluoropropene (R-1234ze(E)), cis-i,3,3,3-tetrafluoropropene (R-1234ze(Z)) and mixtures thereof; (ii) carbon dioxide (CO2 or R-744); and (iii) a third component selected from difluoromethane (R-32), 1,1-difluoroethane (R-152a), fluoroethane (R-161), 1,1,1,2-tetrafluoroethane (R-i 34a), 2,3,3,3-tetrafluoropropene (R-1234yf), 3,3,3-trifluoropropene (R-i 243zf), 1,1,1 -trifluoropropane (R-263fb), 1,1,1,2,3-pentafluoropropane (R-245eb), propylene (R-1270), propane (R-290), n-butane (R-600), isobutane (R-600a), ammonia (R-717) and mixtures thereof.

All of the chemicals herein described are commercially available. For example, the fluorochemicals may be obtained from Apollo Scientific (UK).

Typically, the compositions of the invention contain trans-i,3,3,3-tetrafluoropropene (R- i234ze(E)). The majority of the specific composition described herein contain R-i234ze(E). It is to be understood, of course, that some or all of the R-i234ze(E) in such compositions can be replaced by R-i234ze(Z). The trans isomer is currently preferred, however.

Typically, the composition of the invention contain at least about 5 % by weight R-i234ze(E), preferably at least about 15 % by weight. In one embodiment, the compositions of the invention contain at least about 45 % by weight R-i234ze(E), for example from about 50 to about 98 % by weight.

The preferred amounts and choice of components for the invention are determined by a combination of properties: (a) Flammability: non flammable or weakly flammable compositions are preferred.

(b) Effective operating temperature of the refrigerant in an air conditioning system evaporator.

(c) Temperature "glide" of the mixture and its effect on heat exchanger performance.

(d) Critical temperature of the composition. This should be higher than the maximum expected condenser temperature.

The effective operating temperature in an air conditioning cycle, especially automotive air conditioning, is limited by the need to avoid ice formation on the air-side surface of the refrigerant evaporator. Typically air conditioning systems must cool and dehumidify humid air; so liquid water will be formed on the air-side surface. Most evaporators (without exception for the automotive application) have finned surfaces with narrow fin spacing. If the evaporator is too cold then ice can be formed between the fins, restricting the flow of air over the surface and reducing overall performance by reducing the working area of the heat exchanger.

It is known for automotive air-conditioning applications (Modern Refrigeration and Air Conditioning by AD Althouse et al, 1988 edition, Chapter 27, which is incorporated herein by reference) that refrigerant evaporation temperatures of -2 00 or higher are preferred to ensure that the problem of ice formation is thereby avoided.

It is also known that non-azeotropic refrigerant mixtures exhibit temperature "glide" in evaporation or condensation. In other words, as the refrigerant is progressively vaporised or condensed at constant pressure, the temperature rises (in evaporation) or drops (in condensation), with the total temperature difference (inlet to outlet) being referred to as the temperature glide. The effect of glide on evaporation and condensation temperature must also be considered.

The critical temperature of a heat transfer composition should be higher than the maximum expected condenser temperature. This is because the cycle efficiency drops as critical temperature is approached. As this happens, the latent heat of the refrigerant is reduced and so more of the heat rejection in the condenser takes place by cooling gaseous refrigerant; this requires more area per unit heat transferred.

R-410A is commonly used in building and domestic heat pump systems and by way of illustration its critical temperature of about 71 00 is higher than the highest normal condensing temperature required to deliver useful warm air at about 50 00. The automotive duty requires air at about 50 °C so the critical temperature of the fluids of the invention should be higher than this if a conventional vapour compression cycle is to be utilised. Critical temperature is preferably at least 15K higher than the maximum air temperature.

In one aspect, the compositions of the invention have a critical temperature of greater than about 65 00 preferably greater than about 70 00.

The carbon dioxide content of the compositions of the invention is limited primarily by considerations (b) and/or (c) and/or (d) above. Conveniently, the compositions of the invention typically contain up to about 35 % by weight R-744, preferably up to about 30 % by weight.

In a preferred aspect, the compositions of the invention contain from about 4 to about 30 % R-744 by weight, preferably from about 4 to about 28 % by weight, or from about 8 to about 30 % by weight, or from about 10 to about 30 % by weight.

The content of the third component, which may include flammable refrigerants (such as R-32, R-152a, R-161, propylene or propane), is selected so that even in the absence of the carbon dioxide element of the composition, the residual fluorocarbon mixture has a lower flammable limit in air at ambient temperature (e.g. 23°C) (as determined in the ASHRAE-34 12 litre flask test apparatus) which is greater than 5% v/v, preferably greater than 6% vlv, most preferably such that the mixture is non-flammable. The issue of flammability is discussed further later in this specification.

Typically, the compositions of the invention contain up to about 60 % by weight of the third component. Preferably, the compositions of the invention contain up to about 50 % by weight of the third component. Conveniently, the compositions of the invention contain up to about 45 % by weight of the third component. In one aspect, the compositions of the invention contain from about 1 to about 40 % by weight of the third component.

In one embodiment, the compositions of the invention comprise from about 10 to about % R-1234ze(E) by weight, from about 2 to about 30 % by weight R-744, and from about 3 to about 60 % by weight of the third component.

As used herein, all % amounts mentioned in compositions herein, including in the claims, are by weight based on the total weight of the compositions, unless otherwise stated.

For the avoidance of doubt, it is to be understood that the stated upper and lower values for ranges of amounts of components in the compositions of the invention described herein may be interchanged in any way, provided that the resulting ranges fall within the broadest scope of the invention.

The compositions of the invention may consist essentially of (or consist of) the first component (e.g. R-1234ze(E)), R-744 and the third component.

By the term "consist essentially of", we mean that the compositions of the invention contain substantially no other components, particularly no further (hydro)(fluoro)compounds (e.g. (hydro)(fluoro)alkanes or (hydro)(fluoro)alkenes) known to be used in heat transfer compositions. We include the term "consist of" within the meaning of "consist essentially of".

For the avoidance of doubt, any of the compositions of the invention described herein, including those with specifically defined compounds and amounts of compounds or components, may consist essentially of (or consist of) the compounds or components defined in those compositions.

In one embodiment, the third component is selected from R-32, R-152a, R-161, 1R- 134a, R-1234y1, R-1243zf, R-1270, R-290 and mixtures thereof. Preferably, the third component is selected from R-32, R-152a, R-161, IR-134a, R-1234yf, R-1270, R-290 and mixtures thereof.

In one aspect, the third component contains only one of the listed components. For example, the third component may contain only one of difluoromethane (R-32), 1,1- difluoroethane (R-1 52a), fluoroethane (R-1 61), 1,1,1,2-tetrafluoroethane (R-1 34a), R- 1234yf, propylene or propane. Thus, the compositions of the invention may be ternary blends of R-1234ze(E), R-744 and one of the listed third components (e.g. R-32, R-152a, R-161, R-134a, R-1234yf, propylene or propane).

However, mixtures of one or more of these compounds can be used as the third component. For example, the third component may include R-1 34a together with one of R-32, R-152a, R-161, R-1234yf, propylene or propane. The R-134a typically is included to reduce the flammability of the equivalent composition that does not contain R-1 34a.

Preferably, the compositions of the invention which contain R-1 34a are non-flammable at a test temperature of 60°C using the ASHRAE-34 methodology. Advantageously, the mixtures of vapour that exist in equilibrium with the compositions of the invention at any temperature between about -20°C and 60°C are also non-flammable.

By "substantially no", we include the meaning that the compositions of the invention contain 0.5% by weight or less of the stated component, preferably 0.1 % or less, based on the total weight of the composition.

Certain compositions of the invention may contain substantially no: (i) 2,3,3,3-tetrafluoropropene (R-1234y1), (ii) cis-1,3,3,3-tetrafluoropropene (R-1234ze(Z)), and/or (iii) 3,3,3-trifluoropropene (R-1 243zf).

The compositions of the invention have zero ozone depletion potential.

Typically, the compositions of the invention have a GWP that is less than 1300, preferably less than 1000, more preferably less than 800, 500, 400, 300 or 200, especially less than 150 or 100, even less than 50 in some cases. Unless otherwise stated, IPCC (Intergovernmental Panel on Climate Change) TAR (Third Assessment Report) values of GWP have been used herein.

Advantageously, the compositions are of reduced flammability hazard when compared to the third component(s) alone, e.g. R-32, R-161, R-152a, propane or propylene.

Preferably, the compositions are of reduced flammability hazard when compared to R-l234y1.

In one aspect, the compositions have one or more of (a) a higher lower flammable limit; (b) a higher ignition energy; or (c) a lower flame velocity compared to the third component(s) such as R-32, R-152a, R-161, propane, propylene or R-1234yf. In a preferred embodiment, the compositions of the invention are non-flammable.

Advantageously, the mixtures of vapour that exist in equilibrium with the compositions of the invention at any temperature between about -20°C and 60°C are also non-flammable.

Flammability may be determined in accordance with ASH RAE Standard 34 incorporating the ASTM Standard E-681 with test methodology as per Addendum 34p dated 2004, the entire content of which is incorporated herein by reference.

In some applications it may not be necessary for the formulation to be classed as non-flammable by the ASHRAE-34 methodology; it is possible to develop fluids whose flammability limits will be sufficiently reduced in air to render them safe for use in the application, for example if it is physically not possible to make a flammable mixture by leaking the refrigeration equipment charge into the surrounds.

R-1234ze(E) is non-flammable in air at 23°C, although it exhibits flammability at higher temperatures in humid air. We have determined by experimentation that mixtures of R- 1234ze(E) with flammable fluorocarbons such as R-32, R-152a or R-161 will remain non-flammable in air at 23 °C if the "fluorine ratio" Rf of the mixture is greater than about 0.57, where Rf is defined per gram-mole of the overall refrigerant mixture as: Rf = (gram-moles of fluorine)/(gram-moles fluorine + gram-moles hydrogen) Thus for R-161, Rf = 1/(1+5) = 1/6 (0.167) and it is flammable, in contrast R-1234ze(E) has Rf = 4/6 (0.667) and it is non-flammable. We found by experiment that a 20% v/v mixture of R-161 in R-1234ze(E) was similarly non-flammable. The fluorine ratio of this non-flammable mixture is 0.2*(116) + 0.8*(416) = 0.567.

The validity of this relationship between flammability and fluorine ratio of 0.57 or higher has thusfar been experimentally proven for HFC-32, HFC-152a and mixtures of HFC-32 with HFC-152a.

Takizawa et al, Reaction Stoichiometry for Combustion of Fluoroethane Blends, ASHRAE Transactions 112(2) 2006 (which is incorporated herein by reference), shows there exists a near-linear relationship between this ratio and the flame speed of mixtures comprising R-152a, with increasing fluorine ratio resulting in lower flame speeds. The data in this reference teach that the fluorine ratio needs to be greater than about 0.65 for the flame speed to drop to zero, in other words, for the mixture to be non-flammable.

Similarly, Minor et al (Du Pont Patent Application W02007/053697) provide teaching on the flammability of many hydrofluoroolefins, showing that such compounds could be expected to be non-flammable if the fluorine ratio is greater than about 0.7.

In view of this prior art teaching, it is unexpected that that mixtures of R-1234ze(E) with flammable fluorocarbons such as R-32, R-152a or R-161 will remain non-flammable in air at 23 °C if the fluorine ratio Rf of the mixture is greater than about 0.57.

Furthermore, we identified that if the fluorine ratio is greater than about 0.46 then the composition can be expected to have a lower flammable limit in air of greater than 6% v/v at room temperature.

By producing low-or non-flammable R-744/third component/R-1234ze(E) blends containing unexpectedly low amounts of R-1234ze(E), the amounts of the third component, in particular, in such compositions are increased. This is believed to result in heat transfer compositions exhibiting increased cooling capacity and/or decreased pressure drop, compared to equivalent compositions containing higher amounts of (e.g. almost 100 %) R-1234ze(E).

Thus, the compositions of the invention exhibit a completely unexpected combination of low-/non-flammability, low GWP and improved refrigeration performance properties.

Some of these refrigeration performance properties are explained in more detail below.

Temperature glide, which can be thought of as the difference between bubble point and dew point temperatures of a zeotropic (non-azeotropic) mixture at constant pressure, is a characteristic of a refrigerant; if it is desired to replace a fluid with a mixture then it is often preferable to have similar or reduced glide in the alternative fluid. In an embodiment, the compositions of the invention are zeotropic.

The compositions of the invention preferably have energy efficiency at least 95% (preferably at least 98%) of R-134a under equivalent conditions, while having reduced or equivalent pressure drop characteristics and cooling capacity at 95% or higher of R-134a values. Advantageously the compositions have higher energy efficiency and lower pressure drop characteristics than R-134a under equivalent conditions. The compositions also advantageously have better energy efficiency and pressure drop characteristics than R-1234yf alone.

Preferably, the heat transfer device is a refrigeration device or (a static) air conditioning system. Advantageously, the method further comprises the step of obtaining an allocation of greenhouse gas (e.g. carbon dioxide) emission credit.

In accordance with the retrofitting method described above, an existing heat transfer fluid can be fully removed from the heat transfer device before introducing a composition of the invention. An existing heat transfer fluid can also be partially removed from a heat transfer device, followed by introducing a composition of the invention.

In another embodiment wherein the existing heat transfer fluid is R-134a, and the composition of the invention contains R134a, R-1234ze(E), R-744, any other third component and/or R-125 present (and optional components such as a lubricant, a stabiliser or an additional flame retardant), R-1234ze(E) and R-744, etc, can be added to the R-1 34a in the heat transfer device, thereby forming the compositions of the invention, and the heat transfer device of the invention, in situ. Some of the existing R-134a may be removed from the heat transfer device prior to adding the R-1234ze(E), R-744, etc, to facilitate providing the components of the compositions of the invention in the desired proportions.

Thus, the invention provides a method for preparing a composition and/or heat transfer device of the invention comprising introducing R-1234ze(E), R-744, any other third component in addition to R-134a, any R-125 desired, and optional components such as a lubricant, a stabiliser or an additional flame retardant, into a heat transfer device containing an existing heat transfer fluid which is R-134a.

The compositions can then be added to a heat transfer device (or used in any other way as defined herein) that does not contain R-1 34a or any other existing heat transfer fluid, such as a device from which R-134a or any other existing heat transfer fluid have been removed.

In a further aspect of the invention, there is provided a method for reducing the environmental impact arising from operation of a product comprising an existing compound or composition, the method comprising replacing at least partially the existing compound or composition with a composition of the invention. Preferably, this method comprises the step of obtaining an allocation of greenhouse gas emission credit.

By environmental impact we include the generation and emission of greenhouse warming gases through operation of the product.

As mentioned above, this environmental impact can be considered as including not only those emissions of compounds or compositions having a significant environmental impact from leakage or other losses, but also including the emission of carbon dioxide arising from the energy consumed by the device over its working life. Such environmental impact may be quantified by the measure known as Total Equivalent Warming Impact (TEWI). This measure has been used in quantification of the environmental impact of certain stationary refrigeration and air conditioning equipment, including for example supermarket refrigeration systems (see, for example, http:/!enwikipediaorq!wikUTotal equivalentwarmin impact).

The environmental impact may further be considered as including the emissions of greenhouse gases arising from the synthesis and manufacture of the compounds or compositions. In this case the manufacturing emissions are added to the energy consumption and direct loss effects to yield the measure known as Life-Cycle Carbon Production (LCCP, see for example http://vvsae.orq!eventsIaars/rresentaUonsi2OO7par)asavv3.df). The use of LCCP is common in assessing environmental impact of automotive air conditioning systems.

Emission credit(s) are awarded for reducing pollutant emissions that contribute to global warming and may, for example, be banked, traded or sold. They are conventionally expressed in the equivalent amount of carbon dioxide. Thus if the emission of 1 kg of R- 134a is avoided then an emission credit of 1x1300 = 1300 kg 002 equivalent may be awarded.

In another embodiment of the invention, there is provided a method for generating greenhouse gas emission credit(s) comprising (i) replacing an existing compound or composition with a composition of the invention, wherein the composition of the invention has a lower GWP than the existing compound or composition; and (ii) obtaining greenhouse gas emission credit for said replacing step.

In a preferred embodiment, the use of the composition of the invention results in the equipment having a lower Total Equivalent Warming Impact, and/or a lower Life-Cycle Carbon Production than that which would be attained by use of the existing compound or composition.

These methods may be carried out on any suitable product, for example in the fields of air-conditioning, refrigeration (e.g. low and medium temperature refrigeration), heat transfer, blowing agents, aerosols or sprayable propellants, gaseous dielectrics, cryosurgery, veterinary procedures, dental procedures, fire extinguishing, flame suppression, solvents (e.g. carriers for flavorings and fragrances), cleaners, air horns, pellet guns, topical anesthetics, and expansion applications. Preferably, the field is air-conditioning or refrigeration.

Examples of suitable products include heat transfer devices, blowing agents, foamable compositions, sprayable compositions, solvents and mechanical power generation devices. In a preferred embodiment, the product is a heat transfer device, such as a refrigeration device or an air-conditioning unit.

The existing compound or composition has an environmental impact as measured by GWP and/or TEWI and/or LCCP that is higher than the composition of the invention which replaces it. The existing compound or composition may comprise a fluorocarbon compound, such as a perfluoro-, hydrofluoro-, chlorofluoro-or hydrochlorofluoro-carbon compound or it may comprise a fluorinated olefin Preferably, the existing compound or composition is a heat transfer compound or composition such as a refrigerant. Examples of refrigerants that may be replaced include R-134a, R-152a, R-1234yf, R-410A, R-407A, R-407B, R-407C, R507, R-22 and R-404A. The compositions of the invention are particularly suited as replacements for R- 134a, R-152a or R-1234yf, especially R-134a or R-1234yf.

Any amount of the existing compound or composition may be replaced so as to reduce the environmental impact. This may depend on the environmental impact of the existing compound or composition being replaced and the environmental impact of the replacement composition of the invention. Preferably, the existing compound or composition in the product is fully replaced by the composition of the invention.

The invention is illustrated by the following non-limiting examples.

Examples

Flammability The flammability of certain compositions of the invention in air at atmospheric pressure and controlled humidity was studied in a flame tube test as follows.

The test vessel was an upright glass cylinder having a diameter of 2 inches. The ignition electrodes were placed 60 mm above the bottom of the cylinder. The cylinder was fitted with a pressure-release opening. The apparatus was shielded to restrict any explosion damage. A standing induction spark of 0.5 second duration was used as the ignition source.

The test was performed at 23 or 35 °C (see below). A known concentration of fuel in air was introduced into the glass cylinder. A spark was passed through the mixture and it was observed whether or not a flame detached itself from the ignition source and propagated independently. The gas concentration was increased in steps of 1 % vol. until ignition occurred (if at all). The results are shown below (all compositions are v/v basis unless otherwise stated).

b LFL = lower flammable limit and UFL = upper flammable limit Incomplete propagation The ternary composition 4 % 002, 10 % R-134a and 86 % R-1234ze(E) by weight was shown to be non-flammable at 23 °C. At 35 °C, it was significantly less flammable than corresponding Ri 34a/R1 234y1 and Ri 34a1R1234ze(E) mixtures.

Modelled Performance Data Generation of accurate physical property model The physical properties of R-1234yf and R-1234ze(E) required to model refrigeration cycle performance, namely critical point, vapour pressure, liquid and vapour enthalpy, liquid and vapour density and heat capacities of vapour and liquid were accurately determined by experimental methods over the pressure range 0-200bar and temperature range -40 to 200°C, and the resulting data used to generate Helmholtz free energy equation of state models of the Span-Wagner type for the fluid in the NIST REFPROP Version 8.0 software, which is more fully described in the user guide vnist.qov!srd!PDFfiIes!REFPR0P8PDF, and is incorporated herein by reference.

The variation of ideal gas enthalpy of both fluids with temperature was estimated using molecular modelling software Hyperchem v7.5 (which is incorporated herein by reference) and the resulting ideal gas enthalpy function was used in the regression of the equation of state for these fluids. The predictions of this model for R1234yf and R1234ze(E) were compared to the predictions yielded by use of the standard files for R1234yf and R1234ze(E) included in REFPROP Version 9.0 (incorporated herein by reference). It was found that close agreement was obtained for each fluid's properties.

The vapour liquid equilibrium behaviour of R-1234ze(E) was studied in a series of binary pairs with carbon dioxide, R-32, R-125, R-134a, R-152a, R-161, propane and propylene over the temperature range -40 to +60°C, which encompasses the practical operating range of most refrigeration and air conditioning systems. The composition was varied over the full compositional space for each binary in the experimental programme, Mixture parameters for each binary pair were regressed to the experimentally obtained data and the parameters were also incorporated into the REFPROP software model. The academic literature was next searched for data on the vapour liquid equilibrium behaviour of carbon dioxide with the hydrofluorocarbons R-32, R-125, R-152a, R-161 and R-152a. The VLE data obtained from sources referenced in the article Applications of the simple multi-fluid model to correlations of the vapour-liquid equilibrium of refrigerant mixtures containing carbon dioxide, by R. Akasaka, Journal of Thermal Science and Technology, 159-168, 4, 1, 2009 (which is incorporated herein by reference) were then used to generate mixing parameters for the relevant binary mixtures and these were then also incorporated into the REFPROP model. The standard REFPROP mixing parameters for carbon dioxide with propane and propylene were also incorporated to this model.

The resulting software model was used to compare the performance of selected fluids of the invention with R-134a in a heat pumping cycle application.

Heat rumrinQ cycle comrarison In a first comparison the behaviour of the fluids was assessed for a simple vapour compression cycle with conditions typical of automotive heat pumping duty in low winter ambient temperatures. In this comparison pressure drop effects were included in the model by assignation of a representative expected pressure drop to the reference fluid (R-134a) followed by estimation of the equivalent pressure drop for the mixed refrigerant of the invention in the same equipment at the same heating capacity. The comparison was made on the basis of equal heat exchanger area for the reference fluid (R-1 34a) and for the mixed fluids of the invention. The methodology used for this model was derived using the assumptions of equal effective overall heat transfer coefficient for refrigerant condensation, refrigerant evaporation, refrigerant liquid subcooling and refrigerant vapour superheating processes to derive a so-called UA model for the process. The derivation of such a model for nonazeotropic refrigerant mixtures in heat pump cycles is more fully explained in the reference text Vapor Compression Heat Pumps with refrigerant mixtures by R Radermacher & Y Hwang (pub Taylor & Francis 2005) Chapter 3, which is incorporated herein by reference.

Briefly, the model starts with an initial estimate of the condensing and evaporating pressures for the refrigerant mixture and estimates the corresponding temperatures at the beginning and end of the condensation process in the condenser and the evaporation process in the evaporator. These temperatures are then used in conjunction with the specified changes in air temperatures over condenser and evaporator to estimate a required overall heat exchanger area for each of the condenser and evaporator. This is an iterative calculation: the condensing and evaporating pressures are adjusted to ensure that the overall heat exchanger areas are the same for reference fluid and for the mixed refrigerant.

For the comparison the worst case for heat pumping in automotive application was assumed with the following assumptions for air temperature and for R-134a cycle conditions.

Cycle conditions Ambient air temperature on to condenser and evaporator -15°C Air temperature leaving evaporator: -25°C Air temperature leaving condenser (passenger air) +45°C R134a evaporating temperature -30°C R-134a condensing temperature +50°C Subcooling of refrigerant in condenser 1 K Superheating of refrigerant in evaporator 5K Compressor suction temperature 0°C Compressor isentropic efficiency 66% Passenger air heating load 2kW Pressure drop in evaporator for R-134a 0.O3bar Pressure drop in condenser for R-134a O.O3bar Pressure drop in suction line for R-134a O.O3bar The model assumed countercurrent flow for each heat exchanger in its calculation of effective temperature differences for each of the heat transfer processes.

Condensing and evaporating temperatures for compositions was adjusted to give equivalent usage of heat exchange area as reference fluid. The following input parameters were used.

Parameter ________ Reference Refrigerant R134a Mean condensertemperature °C 50 Mean evaporator temperature °C -30 Condenser subcooling K 1 Evaporator superheat K 5 Suction diameter mm 16.2 Heating capacity kW 2 Evaporator pressure drop bar 0.03 Suction line pressure drop bar 0.03 Condenser pressure drop bar 0.03 Compressor suction temperature °C 0 Isentropic efficiency ________ 66% Evaporator air on °C -15.00 Evaporator air off °C -25.00 Condenser air on °C -15.00 Condenser air off °C 45.00 Condenser area 100.0% 100.0% Evaporator area 100.0% 100.0% Using the above model, the performance data for the reference R-1 34a is shown below.

The tables show key parameters of the heat pump cycle, including operating pressures, volumetric heating capacity, energy efficiency (expressed as coefficient of performance for heating COP) compressor discharge temperature and pressure drops in pipework. The volumetric heating capacity of a refrigerant is a measure of the amount of heating which can be obtained for a given size of compressor operating at fixed speed. The coefficient of performance (COP) is the ratio of the amount of heat energy delivered in the condenser of the heat pump cycle to the amount of work consumed by the compressor.

The performance of R-134a is taken as the reference point for comparison of heating capacity, energy efficiency and pressure drop. This fluid is used as a reference for comparison of the ability of the fluids of the invention to be used in the heat pump mode of an automotive combined air conditioning and heat pump system.

It should be noted in passing that the utility of fluids of the invention is not limited to automotive systems. Indeed these fluids can be used in so-called stationary (residential or commercial) equipment. Currently the main fluids used in such stationary equipment are R-410A (having a GWP of 2100) or R22 (having a GWP of 1800 and an ozone depletion potential of 0.05). The use of the fluids of the invention in such stationary equipment offers the ability to realise similar utility but with fluids having no ozone depletion potential and significantly reduced GWP compared to R41OA.

It is evident that fluids of the invention can provide improved energy efficiency compared to R-134a or R-410A. It is unexpectedly found that the addition of carbon dioxide to the refrigerants of the invention can increase the COP of the resulting cycle above that of R- 134a, even in case where admixture of the other mixture components would result in a fluid having worse energy efficiency than R-1 34a.

It is further found for all the fluids of the invention that compositions up to about 30% w/w of CO2 can be used which yield refrigerant fluids whose critical temperature is about 70 °C or higher. This is particularly significant for stationary heat pumping applications where R-410A is currently used. The fundamental thermodynamic efficiency of a vapour compression process is affected by proximity of the critical temperature to the condensing temperature. R-410A has gained acceptance and can be considered an acceptable fluid for this application; its critical temperature is 71 00. It has unexpectedly been found that significant quantities of 002 (critical temperature 31 °C) can be incorporated in fluids of the invention to yield mixtures having similar or higher critical temperature to R-410A. Preferred compositions of the invention therefore have critical temperatures are about 70 °C or higher.

The heating capacity of the preferred fluids of the invention typically exceeds that of R134a. It is thought that R-134a alone, operated in an automotive a/c and heat pump system, cannot provide all of the potential passenger air heating demand in heat pump mode. Therefore higher heating capacities than R-134a are preferred for potential use in an automotive a/c and heat pump application. The fluids of the invention offer the ability to optimise fluid capacity and energy efficiency for both air conditioning and cooling modes so as to provide an improved overall energy efficiency for both duties.

For reference, the heating capacity of R-410A in the same cycle conditions was estimated at about 290% of the R-134a value and the corresponding energy efficiency was found to be about 106% of the R-1 34a reference value.

It is evident by inspection of the tables that fluids of the invention have been discovered having comparable heating capacities and energy efficiencies to R-410A, allowing adaption of existing R-410A technology to use the fluids of the invention if so desired.

Some further benefits of the fluids of the invention are described in more detail below.

At equivalent cooling capacity the compositions of the invention offer reduced pressure drop compared to R-134a. This reduced pressure drop characteristic is believed to result in further improvement in energy efficiency (through reduction of pressure losses) in a real system. Pressure drop effects are of particular significance for automotive air conditioning and heat pump applications so these fluids offer particular advantage for this application.

The use of hydrocarbon components in the compositions of the invention (e.g. the C02/R-1270/R-1234ze(E) and C02/R-290/R-1234ze(E) blends) results in an improved solubility and miscibility of the refrigerant with lubricants. In particular, the inclusion of hydrocarbon improves these properties in relation to synthetic hydrocarbon or mineral oil type lubricants, which can otherwise exhibit poor miscibility and low mutual solubility with hydrofluorocarbons such as R-134a.

Surprisingly, the use of hydrocarbon in the preferred amounts also results in an increase in cooling capacity of the refrigerant greater than may have been predicted using approximate estimation techniques. Without being bound by theory, it is believed that the non-ideal vapour-liquid equilibrium interaction of the hydrocarbons with R-1234ze(E) is responsible for this improvement. This benefit is found with both propane and propene. No azeotrope was found in determination of the vapour liquid equilibrium to exist between propene and R-1234ze(E) in the entire temperature range of relevance to the application (-40 to 60°C) so the effect does not appear to be related to the presence of azeotropes.

In summary, the combination of hydrocarbon together with carbon dioxide and R- 1234ze(E) gives an improved refrigeration performance, more versatility in selection and application of compressor lubricant, without significantly increasing the flammability hazard of R-1234ze(E) itself. This combination of advantages is completely unexpected.

The compositions containing C02/R-134a/R-1234ze(E) are especially attractive since they have non-flammable liquid and vapour phases at 23°C and selected compositions are also wholly non-flammable at 60°C.

The performance of fluids of the invention were compared to binary mixtures of C02/R1234ze(E). For all the ternary and quaternary compositions of the invention apart from C02/R1234yf/R1234ze(E) the energy efficiency of the ternary or quaternary mixtures was increased relative to the binary mixture having equivalent 002 content.

These mixtures therefore represent an improved solution relative to the C02/R1234ze(E) binary refrigerant mixture, at least for CO2 content less than 30% w/w.

It was found that the C02/R1234y1/R1234ze(E) system exhibited worse energy efficiency did than comparable ternary mixtures of CO2 and R1234ze(E) with either R-32, R-134a, R-152a, R-161, propane or propene at equivalent CO2 content. It was possible nonetheless to generate C02/R1234yf/R1234ze(E) mixtures having comparable or slightly higher energy efficiency to R-134a. Thus unexpectedly this ternary fluid system of the invention provides a means to ameliorate the poor intrinsic energy efficiency of R-l234y1. : *
