“…This means that a refrigerant system that is operated at low pressure should be mixed with refrigerants that can operate under low pressure, such as R1234yf, R1234ze, and R134A. R450A [49], R456A [50], R513A [51] and R515A [50], which were mixed with hydrofluoroolefins (HFOs) and operated under low pressure, achieving similar results to R463A operating under high pressure with 36% hydrofluorocarbons (HFCs) R32 and 7% carbon dioxide (CO 2 ) R744 contents in its composition. to R463A operating under high pressure with 36% hydrofluorocarbons (HFCs) R32 and 7% carbon dioxide (CO2) R744 contents in its composition.…”

“…The R463A refrigerant is a nonflammable refrigerant that was developed to be retrofitted to R404A. The hydrofluorocarbons/hydrocarbons/carbon dioxide (HFCs/HCs/CO 2 ) of R463A (GWP = 1494) are an azeotropic mixture of R32 (36%), R125 (30%), R134a (14%), R1234yf (14%), and R744 (6%) [50]. R463A is composed of polyol ester oil (POE), and classified as a Class A1 incombustible and nontoxic refrigerant.…”

“…Systems that operate with R22 [40], R407C [41], R417A [42], R422A [43], R422D [44], R424A [45], R427A [46], and R453A [47] were developed as an alternative to R22 and mixed with HCs and HFCs, as shown in Tables 1 and 2. Systems that operate with R134A [48], R450A [49], R456A [50], R513A [51], and R515A [50] were developed as an alternative to R134A, and mixed with HCs, HFCs, and HFOs, as shown in Table 3. The fourth-generation R404A was the basis for this research, and it is currently the most used refrigerant, as shown in Figure 6.…”

“…R404A is an azeotropic blend of 143a/125/134a with zero ODP, and is nonflammable, nontoxic, and operates under low pressure, but has a GWP of 3922 [52]. R407A [53], R407F [54], R407H [55], R410A [56], R442A [57], R448A [58], R449A [59], R452A [60], R453A [57], and R463A [50] were developed to be retrofitted to replace R404A, and are mixed with HCs, HFOs, R134A, and R32. This is similar to the refrigerant that was developed for R22 and R134A but does not include R463A, which is being presented as a refrigerant for comparative purposes in this research as it is composed of R744 (carbon dioxide), which is a natural refrigerant similar to R445A [61] and R455A [62].…”

This research presents the development of R463A refrigerant, a nonflammable refrigerant that was retrofitted to replace R404A. R463A is primarily composed of hydrofluorocarbons/hydrocarbons/carbon dioxide (HFCs/HCs/CO2), and has global-warming potential (GWP) of 1494. It is a nonazeotropic mixture of R32 (36%), R125 (30%), R134a (14%), R1234yf (14%), and R744 (6%). R463A is composed of polyol ester oil (POE), and it is classified as a Class A1 incombustible and nontoxic refrigerant. R463A has a higher cooling capacity (Qe) than that of R404A, as it is composed of hydrofluorocarbons (HFCs) R32 and carbon dioxide (CO2) R744, and has lower GWP than that of R404A due to the use of hydrofluoroolefins (HFOs) from R1234yf. The results of this research showed that R463A can be retrofitted to replace R404A due to its composition of POE, Class A1 incombustibility, and lower toxicity. The properties of R463A and R404A, as analyzed using national institute of standards and technology (NIST) reference fluid thermodynamic and transport properties database (REFPROP) software and NIST vapor compression cycle model accounting for refrigerant thermodynamic and transport properties (CYCLE_D-HX) software, are in accordance with the CAN/ANSI/AHRI540 standards of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). The normal boiling point of R463A was found to be higher than that of R404A by 23%, with a higher cooling capacity and a 63% lower GWP value than that of R404A. The critical pressure and temperature of R463A were found to be higher than those of R404A; it can be used in a high-ambient-temperature environment, has higher refrigerant and heat-rejection effects, and has lower GWP than that of R404A by 52% due to the HFOs from the R1234yf component. The cooling coefficient of performance (COPc) of R463A was found to be higher than that of R404A by 10% under low-temperature applications. R463A is another refrigerant option that is composed of 7% carbon dioxide (CO2), and is consistent with the evolution of fourth-generation refrigerants that contain a mixture of HFCs, HFOs, HCs, and natural refrigerants, which are required to produce a low-GWP, zero-ozone-depletion-potential (ODP), high-capacity, low-operating-pressure, and nontoxic refrigerant.

This research presents the results of investigation and analysis of the environmentally friendly refrigerant for R22 replacement. All refrigerant properties in this research were based on results from the REFPROP and CYCLE_D-HX software of NIST under CAN/ANSI/AHRI540. The results of this work show that HCs R170, R290, R600, R600a, R601, R601a, R1150 and R1270 can be mixed in HFCs R417A, R417B, R422A, R422B, R422C, R422D, R424A, R437A, R438A and R453A and able to be further developed in the future. All refrigerants are non-flammable refrigerants, non-toxic and zero ODP. The R453A mixed with HCs R600 (0.6%) and R601a (0.6%) and is COPc refrigerant close to that of R22 refrigerant. In conclusion, it can be used as an environmentally friendly and energy efficiency replacement for R22. All refrigerants are also refrigerants that are matched with the 4th generation refrigerants with the use of natural refrigerants.
