“…It also highest refrigerant cost but does not include HCs refrigerant cost compare with HFOs refrigerant cost, which is being presented as a refrigerant for comparative purposes in this research as it is composed of HCs. The properties of hydrocarbon refrigerant that class A3 high flammability as shown in Figure 7 below but zero ODP and GWP nearly zero, shown in Table 10-11 for R170 [66], R290 [67], R600 [68], R600a [69] and Table 2 for R601 [70], R601a [71], R1150 [72], R1270 [73]. The highest boiling of R170 and R1270 were found to be -88.70 °C and -103.8 °C respectively but the critical temperature was found to be 32.17 °C and 9.5 °C.…”

This research presents the development of environmentally-friendly and energy efficient refrigerant for medium temperature refrigeration systems that new azeotropic refrigerant mixture of hydrofluorocarbons and hydrocarbon that can retrofit in the refrigeration system using R404A. The medium back pressure refrigeration testing standard that follow CAN/ANSI/AHRI540 standard air-conditioning, heating, and refrigeration institute (AHRI) and The properties of refrigerants and refrigeration simulation system that used 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. The methodology use decision tree function in datamining by rapid minor software that first of KDnuggets annual software poll that showed new azeotropic refrigerant mixture had cooling capacity, refrigerant effect, GWP and boiling point were lower than R404A but work and pressure for medium temperature refrigeration system of azeotropic refrigerant mixture were higher than R404A. The artificial intelligence (AI) by data mining technic can predictive environmentally-friendly and energy efficient refrigerant for medium temperature refrigeration. The result of refrigerant mixed by R134A, R32, R125 and R1270 and is consistent with the evolution of fourth-generation refrigerants that contain a mixture of HFCs and HCs which are required to produce a low-GWP, zero-ozone-depletionpotential (ODP), high-capacity, low-operating-pressure, and nontoxic refrigerant.

This paper presents the improvement of eco-friendly and power consumption saving refrigerants for refrigeration systems. The novel azeotropic refrigerant mixtures of HFCs and HCs can replace refrigeration systems, and using the R134, R32, R125, and R1270 refrigerants in several compositions found using the decision tree function of the RapidMiner software (which came first in the KDnuggets annual software poll). All refrigerant results are mixed of POE, which is A1 classification refrigerant, non-flammable, and innocuous refrigerant, and using REFPROP software and CYCLE_D-HX software are under the CAN/ANSI/AHRI540 standards. The boiling point of the new refrigerant mix R-No.595 is 4.58%, lower than that of R404A, with a higher refrigerant effect and 50.34% lower GWP value than R404A. The proposed mix R-No.595 can be operated in hot environmental country and has high critical temperature and heat-rejection effects, due to the presence of R32 and R1270. The COPc of R463A is 13.49%, higher than R404A in freeze condition. The novel refrigerant mixes provide alternate refrigerant options mixed of 1% R1270, and which are related with the development of current refrigerants, containing a compose of HFOs and eco refrigerants for producing low-GWP, zero ODP, high-refrigerant effect, low-operating pressure, and innocuous refrigerants.

“…The class properties of hydrocarbon refrigerants are shown in Figure 7 below. Some zero ODP and near-zero GWP Class A3 refrigerants, as shown in Table 10 and 11, are R170 [66], R290 [67], R600 [68], R600a [69] and Table 2 for R601 [70], R601a [71], R1150 [72], and R1270 [73]. The lowest boiling points were found to be -88.70 °C and -103.8 °C, respectively, for R170 and R1270; however, their critical temperatures were found to be 32.17 °C and 9.5 °C.…”
