Background
Mechanical refrigeration systems and related heat transfer devices, such as heat pumps and air conditioners, are well known in the art for industrial, commercial and domestic use. Chlorofluorocarbons (CFCs) were the refrigerants of this system developed in the 30's of the 20 th century. However, since the 80's of the 20 th century, the impact of CFCs on the stratospheric ozone layer has been the focus of attention. In 1987, Montreal protocol was signed by some national governments to protect the global environment and schedule the phase-out of CFC products. CFCs are replaced by more environmentally friendly hydrogen-containing materials, namely Hydrochlorofluorocarbons (HCFCs).
One of the most commonly used hydrochlorofluorocarbon refrigerants is chlorodifluoromethane (HCFC-22). However, subsequent amendments to the montreal protocol accelerated the phase-out of CFCs and also planned the phase-out of HCFCs, including HCFC-22.
To meet the demand for non-flammable, non-toxic alternatives to CFCs and HCFCs, the industry has developed a wide variety of Hydrofluorocarbons (HFCs) with zero ozone depletion potential. R-410A (a 50: 50w/w blend of difluoromethane (HFC-32) and pentafluoroethane (HFC-125)) is used as an industrial replacement for HCFC-22 in air conditioning and freezer applications because it does not contribute to ozone depletion. However, R-410A is not a simple substitute for R-22. Thus, replacing R-22 with R-410A requires redesigning the major components within the heat exchange system, including replacing and redesigning the compressor to accommodate the higher operating pressure and volumetric capacity of R-410A when compared to R-22.
While R-410A has a more acceptable Ozone Depletion Potential (ODP) than R-22, continuing to use R-410A is problematic because it has a high global warming potential of 2088. Thus, there is a need in the art to replace R-410A with a more environmentally friendly alternative.
It is understood in the art that it is highly desirable that alternative heat transfer fluids have a difficult to achieve performance mosaic, including excellent heat transfer characteristics, particularly well-matched to the needs of a particular application, chemical stability, low or no toxicity, non-flammability, lubricant miscibility and/or lubricant compatibility, among others. Furthermore, any replacement of R-410A is preferably matched to the operating conditions of R-410A to avoid modifications or redesign of the system. The development of heat transfer fluids that meet all of these requirements, many of which are unpredictable, is a significant challenge.
With respect to efficiency of use, it is important to note that as the demand for electrical energy increases, a loss in refrigerant thermodynamic performance or energy efficiency can lead to an increase in the use of fossil fuels. Thus, the use of such refrigerants can have negative secondary environmental effects.
Flammability is considered important and, in some cases, a key property for many heat transfer applications. Therefore, it is often beneficial to use the compounds in such compositions to obtain non-flammable refrigerants, if possible. As used herein, the term "non-flammable" refers to a composition that is determined to be non-flammable according to ASTM Standard E-681-2001, as described in ASHRAE Standard 34-2013 and as described in appendix B1 of ASHRAE Standard 34-2013.
It is critical for maintaining system efficiency and proper and reliable functioning of the compressor that the lubricant circulating in the vapor compression heat transfer system be returned to the compressor to perform its intended lubricating function. Otherwise, lubricant may accumulate and stagnate in the coils and pipes of the system, including the heat transfer components. In addition, when lubricant accumulates on the inner surfaces of the evaporator, it reduces the heat exchange efficiency of the evaporator, thereby reducing the efficiency of the system.
R-410A is currently used with polyol ester (POE) lubricants in air conditioning applications because R-410A is miscible with POE at the temperatures experienced during use of such systems. However, R-410A is immiscible with POE at temperatures typically experienced during operation of cryogenic refrigeration systems and heat pump systems. Therefore, unless measures are taken to mitigate this immiscibility, POE and R-410A cannot be used in cryogenic refrigeration or heat pump systems.
It would therefore be desirable to provide compositions that can be used as R-410A substitutes in air conditioning applications. It is an additional benefit to be able to use the compositions of the present invention in, for example, heat pump and cryogenic refrigeration systems, where the compositions do not have the disadvantage of being immiscible with POE at the temperatures experienced during operation of these systems.

Alternatively, the heat transfer composition or refrigerant can be used in a method of retrofitting an existing heat transfer system designed to contain or contain R410A refrigerant, wherein the system is modified for use with the refrigerant of the present invention.
Alternatively, the heat transfer composition or refrigerant may be used in a heat transfer system suitable for use with an R-410A refrigerant.
It is to be understood that when the heat transfer composition is used as a low global warming replacement for R-410A, or in a method for retrofitting an existing heat transfer system designed to contain or contain an R-410A refrigerant, or in a heat transfer system suitable for use with an R-410A refrigerant, the heat transfer composition can consist essentially of the refrigerant of the present invention. Alternatively, the invention encompasses the use of the refrigerants of the invention as a low global warming replacement for R-410A, or a method for retrofitting an existing heat transfer system designed to contain or contain R-410A refrigerant, or in a heat transfer system suitable for use with R-410A refrigerant as described herein.
One skilled in the art will understand when the heat transfer composition is provided as a means for retrofitting an existing heat transfer system as described above.
As described above, the method includes removing at least a portion of the existing R-410A refrigerant from the system. Preferably, the method comprises removing at least about 5 wt.%, about 10 wt.%, about 25 wt.%, about 50 wt.%, or about 75 wt.% of R-410A from the system and replacing it with a heat transfer composition of the present invention.
The compositions of the present invention may be used in systems used or adapted for use with R-410A refrigerants, such as existing or new heat transfer systems.
The compositions of the present invention exhibit many of the desirable characteristics of R-410A, but have a GWP that is much lower than that of R-410A, while having an operating characteristic, i.e., capacity and/or efficiency (COP), that is substantially similar to or substantially matches that of R-410A, and preferably as high as or higher than that of R-410A. This allows the claimed composition to replace R-410A in existing heat transfer systems without requiring any significant system modifications to, for example, condensers, evaporators, and/or expansion valves. Thus, the composition can be used as a direct replacement for retrofit heat exchange systems that have been used with R-410A or are suitable for use with R-410A.
The compositions of the present invention therefore preferably exhibit handling characteristics compared to R-410A, wherein:
-the efficiency (COP) of the composition is 95% to 105% of the efficiency of R-410A; and/or
-a capacity of 95% to 105% of the capacity of R-410A.
In heat transfer systems wherein the compositions of the present invention are used in place of R-410A refrigerant.
Preferably, the compositions of the present invention preferably exhibit handling characteristics compared to R-410A, wherein:
-the efficiency (COP) of the composition is from 100% to 105% of the efficiency of R-410A; and/or
-a capacity of 98% to 105% of the capacity of R-410A.
In heat transfer systems wherein the compositions of the present invention are used in place of R-410A refrigerant.
The term "COP" is a measure of energy efficiency and represents the ratio of refrigeration or cooling capacity to the energy demand of the refrigeration system (i.e., the energy to run the compressor, fan, etc.). COP is the useful output of a refrigeration system, in this case the refrigeration capacity or amount of cooling provided divided by the power required to obtain this output. In essence, it is a measure of the efficiency of the system.
The term "capacity" is the amount of cooling provided by the refrigerant in a refrigeration system, in BTU/h. This is determined experimentally by multiplying the change in enthalpy of the refrigerant as it passes through the evaporator (in BTU/lb) by the mass flow of the refrigerant. Enthalpy can be determined by measuring the pressure and temperature of the refrigerant. The capacity of a refrigeration system relates to the ability to maintain an area to be cooled at a particular temperature.
The term "mass flow rate" is the amount of refrigerant in pounds per pound that passes through a conduit of a given size for a given amount of time.
In order to maintain the reliability of the heat transfer system, it is preferred that the composition of the present invention further exhibits the following characteristics compared to R-410A:
-the exhaust temperature is no more than 10 ℃ higher than the exhaust temperature of R-410A; and/or
-a compressor pressure ratio of 95% to 105% of the compressor pressure ratio of R-410A
In heat transfer systems wherein the compositions of the present invention are used in place of R-410A refrigerant.
It is understood that R-410A is an azeotrope-like composition. Thus, in order to match the claimed compositions well with the operating characteristics of R-410A, the claimed compositions advantageously exhibit low levels of slip. Thus, the claimed composition of the invention can provide evaporator glide of less than 2 ℃, preferably less than 1.5 ℃.

Example 15 miscibility with POE oil
POE oil is widely used in air conditioners and refrigeration systems.
As shown in Table 23 below and in FIG. 1, R-410A is immiscible with POE oil below-22 ℃. Thus, R-410A cannot be used for cryogenic refrigeration applications because POE oil will remain in the evaporator and accumulate.
Furthermore, when R-410A is used under high ambient conditions, R-410A is immiscible with POE oil above 50 ℃, which can cause problems in the condenser and liquid lines (e.g., separated POE oil will be trapped and accumulate).
Conversely, the refrigerant consists of:
about 46% by weight difluoromethane (HFC-32),
about 12% by weight pentafluoroethane (HFC-125), and
about 42% by weight of trifluoroiodomethane (CF) according to the invention3I) Fully miscible with POE oil over the temperature range of-40 ℃ to 80 ℃, as shown in table 23 below:
