“…The components of the R463A is consistent to the R445A, which is a mixture of R1234z3 (85%), R134 (9%), R744 (6%) (HFOs/HFCs/CO2), and also consistent with the components of R455A; which is a mixture of R1234yf (75.5%), R32 (21.5%), R744 (3%) (HFOs/HFCs/Co2.) [26,27]. The R463A, R445A, R455A have a higher cooling capacity (Qe) than the R404A due to the hydrofluorocarbons (HFCs) R32 and carbon dioxide (Co2) R744 in its component, and a lower global warming potential (GWP) than the R404A due to the presence of hydrofluoroolefins (HFOs) by R1234yf [5,21,28].…”

This study presents the performance simulation of the R463A that has been developed to be retrofitted to replace the R404A. The R463A is primarily composed of hydrofluorocarbons/hydrocarbon/carbon dioxide (HFCs/HCs/CO2). The R463A refrigerant (GWP=1494) is a non azeotropic mixture of R32 (36%), R125 (30%), R134a (14%), R1234yf (14%), and R744 (6%). It is composed of polyol ester oil (POE), and classified as a Class A1 incombustible and non-toxic refrigerant. The R463A has a higher cooling capacity (Qe) than the R404A, as it is composed of hydrofluorocarbons (HFCs) R32 and carbon dioxide (CO2) R744, and also has a lower global warming potential (GWP) than the R404A due to the hydrofluoroolefins (HFOs) by R1234yf. The properties of the R463A and R404A that uses the REFPROP and CYCLE_D-HX software, is in accordance to the CAN/ANSI/AHRI540 standard airconditioning , heating, and refrigeration institute (AHRI). The normal boiling point of the R463A was found to be higher than the R404A by 23%, with a higher cooling capacity and a lower GWP value by 63% than the R404A. The critical pressure and temperature of the R463A was found to be higher than the R404A, i.e. it can be used in a high ambient temperature environment, and emits a higher refrigerant effect and heat reject with a lower global warming potential (GWP) than the R404A by 52%, due to its hydrofluoroolefins (HFOs) by R1234yf component. The COP of the R463A was found to be higher than the R404A by 10% under low temperature application.

“…While the research of Mota-Babiloni et al (2018) shows positive results at a full system level, at present there are no published studies available on condensation phenomena of R454C, necessary for the design and optimization of next generation equipment. While there is limited data on R454C, the in-tube condensation of HFC/HFO refrigerant mixtures has received much recent attention in the quest to find the best low GWP fluids.…”

This paper investigates the in-tube, superheated, saturated and subcooled condensation of zeotropic refrigerant mixture R454C. R454C is proposed to replace R404A for commercial refrigeration applications. Quasi-local heat transfer coefficients were measured in a 4.7 mm horizontal tube at mass fluxes ranging from 100-500 kg m-2 s-1 at three different saturation conditions (40, 50 and 50 °C). The resulting data was compared with the nonequilibrium condensation models of Agarwal & Hrnjak (2014), Kondou & Hrnjak (2012) and Xiao & Hrnjak (2017), as well as the equilibrium model of Cavallini et al. (2006) with the Gnielinski (1976) correlation for predictions in subcooled and saturated regions. The additional mass transfer effects were accounted for by applying the Silver (1947), Bell & Ghaly (1973) mixture correction. The non-equilibrium Kondou & Hrnjak (2012) model, with the predictions in the subcooled region from Gnielinski (1976) correlation, agrees best with the data (mean average percent error = 9%). An air-cooled condenser for a 1055 kW refrigeration system is designed by following both the non-equilibrium and equilibrium approaches. This non-equilibrium approach leads to a 4.8% and 9.1% reduction in heat transfer area for R454C and R404A, respectively. R454C condenser area is 17-21% larger than that of a R404A condenser.

“…For the refrigerant used in food industry as shown in Figure 5 below, that show the first refrigerants was R404A of 40%, that have refrigerants develop for R404A [41]. R407A [42], R407F [43], R407H [44], R410A [45], R442A [46], R448A [47], R449A [48], R452A [49], R453A [50], and R463A [51] were developed to be retrofitted to replace R404A, and are mixed with HCs, HFOs, R134A, R32 and R744. These conform to the refrigerantdevelopment trend and are an alternate option that can be mixed with HFC.…”

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.
