“…Kondo et al also supplied a formula to calculate the flammability limits in dry air of ammonia mixtures. R1234ze(E) cannot suppress completely the flammability of R161 (GWP=13, R22 replacement in stationary air conditioning systems) in the range 268 to 328K [39].…”

Climate change is demonstrated through global surface temperatures increase in the last century. To stop this phenomenon, new regulations that ban or taxes greenhouse gas fluids (HFC among them) have being approved. In the medium term, only low-GWP refrigerants will be permitted in developed countries. HFO are synthetic fluids that show similar properties to used HFC. Among them, one of the most promising is R1234ze(E). This refrigerant presents good environmental properties and can be used in most of HVACR applications, pure or mixed with HFC or natural refrigerants (mainly CO2). This paper collects the most relevant research about R1234ze(E) thermophysical and compatibility properties, heat transfer and pressure drop characteristics, and vapour compression system performance; separating those works that considers R1234ze(E) pure or blended. Once analyzed literature available, it can be concluded that pure R1234ze(E) is a good option only in new HVACR systems. Nevertheless, if it is combined with other refrigerants also reduces considerably the final GWP value, maintaining efficiency parameters at levels that allow them to replace R134a, R404A or R410A in existing systems with minor modifications.

“…Previously, the LFL and UFL of R161 were reported as 3.8% and 17.9% respectively, and the LFL and UFL of R152a were reported as 4.9% and 18% respectively. In this section, the flammability limits of R1234ze (E) þ R161 [37] and R1234ze (E) þ R152a were tested out, and the experimental results were shown in Figs.5 and 6.…”

“…In the past few years, manufacturers have also adopted environmentally friendly refrigerants such as R161, R32, R152a, R1270, R1150, R1234yf, etc. R161 (C2H5F) has a zero ozone depletion effect and tremendously low GWP100 (about 12), and also possesses the most promising thermophysical properties and is considered an alternative to R22 [2]. R13I1 a flame retardant provides outstanding environmental performance with Low Global Warming Potential (LGWP about 1) and zero ozone depletion effect [3].…”

The present issues related to global warming have attracted refrigerants with low Global Warming Potential (GWP). Two of the most promising low-GWP refrigerants, R32 (difluoromethane) and R290 (propane) are flammable. The addition of a flame retardant to R290 or R32 can enhance their flammable characteristics. Trifluoroiodomethane (R13I1) is a flame retardant with an enormously low global warming and can be used as a component of the refrigerant. In addition, dispersing nanoparticles in these refrigerants improves thermal conductivity. Nanorefrigerants are new refrigerants possessing better heat dissipation performance over traditional refrigerants. An ultra-low GWP mixture refrigerant consisting of R32, R161 and trifluoroiodomethane with aluminum oxide (Al2O3) nanoparticles is used in the present study. Simulation Model-based theoretical results of R410a and with R410a/Al2O3, mixture refrigerant (R32, R161 and trifluoroiodomethane) and nanorefrigerant (R32, R161 and trifluoroiodomethane with aluminum oxide nanoparticles) are carried. The study shows the coefficient of performance (COP) of R410a/Al2O3 and M (R32/R161/R13I1)/Al2O3 increased by 47.3% and 89.8% respectively. The power-saving up to 31.8% and 47.2% at a volume concentration of 0.09%. The comparison has been made with reference to the R410a/Al2O3 system. The thermophysical properties of refrigerants have been calculated using REFPROP (NIST properties of fluid reference). The theoretical model-based calculations are computed in MATLAB software. This study provides an insight in providing appropriate refrigerant substitutes for air conditioning systems.
