Abstract
Description
[Technical Field]
[0001] The present invention provides compositions, methods and compositions that have utility in heat exchange applications, including air conditioning and refrigeration applications. In a particular embodiment, the present invention relates to a method and system for producing a refrigerant R-410A. The present invention relates to compositions useful in heat transfer systems of the type that may be used. , particularly as a replacement for refrigerant R-410A for heating and cooling applications, and By installing additional heat exchange systems, including systems designed for use with It is useful for [Background technology]
[0002] Mechanical refrigeration systems and heat pumps for industrial, commercial and domestic use and related heat transfer devices such as air conditioners are well known in the art. Chlorofluorocarbons (CFCs) are used as refrigerants for such systems. However, since the 1980s, the impact of CFCs on the stratospheric ozone layer has been In 1987, the phase-out of CFC products was announced. Many of the ideas in the Montreal Protocol to protect the global environment were put forward, setting a timetable for The government of Japan signed the agreement. Hydrochlorofluorocarbons (HCFCs) replaced CFCs .
[0003] One of the most commonly used hydrochlorofluorocarbons is chlorodifluorocarbon. However, subsequent amendments to the Montreal Protocol The positive impact of this is to accelerate the phase-out of CFCs and to phase-out HCFCs, including HCFC-22. I scheduled it.
[0004] In response to the need for non-flammable, non-toxic alternatives to CFCs and HCFCs, the industry: Some hydrofluorocarbons have an ozone depletion potential of zero. HFCs were developed to reduce CO₂ emissions in air conditioning and refrigeration applications because they do not contribute to ozone depletion. R-410A (difluoromethane (HFC-32) and A 50:50 w / w blend of pentafluoroethane (HFC-125) was employed. However, R-410A is not a drop-in replacement for R-22. The replacement of R-22 with R-410A is substantially less than that of R-410A compared to R-22. Heat exchangers, including compressor replacement and redesign to accommodate higher operating pressures and volumes This required the redesign of key components within the exchange system.
[0005] R-410A has a lower acceptable ozone depletion potential than R-22. However, its global warming potential is high at 2088, so it is not suitable for use with R-410A. Continued use is problematic. Therefore, R-410A is being replaced by more environmentally acceptable alternatives. There is a need in the art for a replacement for
[0006] As shown in Table 1, the EU has set a number of HFCs that can be sold commercially within the EU from 2015 onwards. Implemented F-gas regulations to limit H-gas sales in 2015 by 2030. Only 21% of the amount of FC will be available. Therefore, as a long-term solution, It is desirable to limit it to less than 427.
[0007] [Table 1] * The 2015 GWP levels are based on the 2012 UNEP data, which shows no growth rate increase. Based on research.
[0008] Alternative heat transfer fluids may be available that offer superior heat transfer properties, particularly those well suited to the needs of a particular application. (heat transfer properties compatible with the material), chemical stability, low or no toxicity, non-flammability, lubricant compatibility, and and / or possess a mosaic of difficult-to-achieve properties, including lubricant compatibility. It is understood in the art that any replacement for R-410A is desirable. Ideally, the operating conditions for R-410A should be adjusted to avoid system modifications or redesign. These requirements, many of which are unpredictable, are a good match. Developing a heat transfer fluid that satisfies all requirements is a major challenge.
[0009] Regarding efficiency of use, the loss of thermodynamic performance or energy efficiency of the refrigerant is equivalent to the loss of electrical energy. Note that increased demand for renewable energy may result in increased use of fossil fuels. Therefore, the use of such refrigerants has secondary negative impacts on the environment. This will happen.
[0010] Flammability is considered an important property for many heat transfer applications. When used in, the term "non-flammable" refers to ASTM Standard E-681-2009 S Standard Test Method for Concentration Li mits of Flammability of Chemicals (Vapors) and Gases) in accordance with ASHRAE Standard 34-2016 Designation and Safety Classification of Refrigerants and ASHRAE Standard 34-2016 A Refers to compounds or compositions that are judged to be non-flammable under the conditions described in Appendix B1. which is incorporated herein by reference and is referred to herein for convenience as the "Non-flammable Test "It is called "
[0011] The lubricant circulating in the vapor compression heat transfer system performs its intended lubricating function. The fact that the air is returned to the compressor before use is essential to maintaining system efficiency and ensuring proper operation of the compressor. It is very important to ensure that the lubricant does not build up and leak into the system, including in the heat transfer components. In addition, lubricant can accumulate on the inner surface of the evaporator. This reduces the heat exchange efficiency of the evaporator, thereby reducing the efficiency of the system.
[0012] R-410A is a polyol ester (poly ester) at temperatures encountered during use in such systems. Because R-410A is miscible with polyethylene terephthalate (POE), it is currently being replaced by POE in air conditioning applications. However, R-410A is commonly used in low-temperature refrigeration systems. It is immiscible with POE at temperatures typically encountered during operation of gas and heat pump systems. Therefore, unless measures are taken to mitigate this incompatibility, POE and R-41 0A cannot be used in low temperature refrigeration or heat pump systems.
[0013] Applicants are developing a system for air conditioning applications, particularly rooftop air conditioning, variable refrigerant flow, In residential and commercial air conditioning applications, including VRF (Ventilated Flow) air conditioning and chiller air conditioning applications It is therefore desirable to provide a composition that can be used as a substitute for R-410A. Applicants also believe that the compositions, methods, and systems of the present invention can be used to, for example, In heat pump and low-temperature refrigeration systems, the temperatures that occur during the operation of these systems It has been realized that it has the advantage of eliminating the drawback of being immiscible with POE. .

The determined temperature is preferably + / - 2°C, more preferably + / - 1°C, even more preferably + / - 1°C of the specified temperature. Preferably + / - 0.5°C.
[0055] The term "capacity" refers to the amount of cooling provided by the refrigerant in a refrigeration system (B TU / hr), which is the enthalpy of the refrigerant as it passes through the evaporator (BTU / lb ) multiplied by the mass flow rate of the refrigerant. The enthalpy is The capacity of a cooling system can be determined by measuring the pressure and temperature of the refrigerant. The capacity of a refrigerant is related to its ability to maintain the area it is placed in at a specific temperature. represents the amount of heating and is a function of the compressor's ability to deliver the amount of heat for a given volumetric flow rate of refrigerant. In other words, given a particular compressor, a refrigerant with a higher capacity will It will provide more cooling or heating power.
[0056] The term "coefficient of performance" (hereinafter referred to as "COP (coefficient of performance)") means The relative thermodynamic behavior of refrigerants in a particular heating or cooling cycle involving evaporation or condensation of the refrigerant. It is a widely accepted measure of refrigerant performance that is particularly useful for expressing efficiency. This term refers to the effective cooling ratio of the energy applied by the compressor during the compression of the vapor. It represents the ratio of storage or cooling capacity and therefore the ratio of the heat transfer fluid, such as a refrigerant, to the volumetric flow rate. represents the ability of a given compressor to deliver a given amount of heat. In other words, considering a particular compressor, A refrigerant with a higher COP will provide more cooling or heating power. One means of estimating the COP of a refrigerant at operating conditions is to calculate the COP for a standard refrigeration cycle. from the thermodynamic properties of refrigerants using analytical techniques (e.g., RCDowning, FLUOROCARBON REF, incorporated herein by reference. RIGERANTS HANDBOOK,Chapter 3,Prentice-Ha ll, 1988).
[0057] The phrase "discharge temperature" refers to the temperature of the refrigerant at the outlet of the compressor. The advantage of this is that it operates on the thermal protection aspects of the system, which are preferably designed to protect the compressor components. It allows the use of existing equipment without increasing the cost, and high-performance liquid injection to lower the discharge temperature The aim is to avoid the use of expensive control devices.
[0058] The term "global warming potential" (hereinafter "GWP") refers to the contribution of various gases to global warming. It was developed to make it possible to compare the effects of one ton of a gas on the How much energy does an emission use over a given period of time compared to the emission of one tonne of carbon dioxide? The higher the GWP, the more energy a given gas absorbs compared to CO2. This will warm the Earth more over that period.

The refrigerant / lubricant fluid exhibited a smaller than ideal appearance and relatively high TAN and R-23 values. This result is achieved despite the inclusion of BHT stabilizers. The addition of 2% alkylated naphthalenes according to the invention reduces the Dramatic and predictable improvements in all tested stability outcomes, including dramatic and order-of-magnitude improvements in Bringing about external improvements.

[0405] Example 15 - Stabilizer for heat transfer compositions containing refrigerants and lubricants Add 10% by weight of alkylated naphthalene (AN4) based on the weight of the lubricant. In addition, 1000 ppm by weight (0.1% by weight) of ADM (ADM4) was also added. The test of Example 14 is repeated, except that the results (denoted E15) are compared with those of Comparative Example 1 (denoted CE1). ), along with the results from Example 10 (denoted as E10), and Example 14 (denoted as E14). are reported in Table 12 below.

[0409] Example 17 - Stabilizer for heat transfer compositions containing refrigerants and lubricants The lubricant has a viscosity of about 68 cSt at 40°C and a water content of 300 ppm or less. The test of Example 15 is repeated except with ISO 68 PVE (lubricant c). The results were as follows: Lubricant appearance - extremely clear TAN-<0.1mgKOH / g R-23-0.028% by weight
[0410] Example 18 - Stabilizer for heat transfer compositions containing refrigerants and lubricants The lubricant has a viscosity of about 32 cSt at 40°C and a water content of 300 ppm or less. The test of Example 15 is repeated except with ISO 32 PVE (lubricant c). The results were similar to those from Example 17.

Each is tested at different lubricant to refrigerant weight ratios and at different temperatures. The results are reported in Table 11 below.
[0412] [Table 16]
[0413] As can be seen from the table above, R-410A is immiscible with POE oil below approximately -22°C. Therefore, unless measures are taken to overcome the accumulation of POE oil in the evaporator, R-41 R-410A cannot be used for low-temperature refrigeration. It is immiscible with E oil, which is why it is used in condensers and This can cause problems in the pumping lines (e.g., the separated POE oil can become trapped and accumulate). On the contrary, applicants have surprisingly and unexpectedly found that the present invention The refrigerant is completely miscible with POE oil over the temperature range of -40°C to 80°C, but and have been found to provide substantial and unexpected advantages when used in such systems. did.
