Saturation properties of the refrigerant 143A

Viscosity of Compressed Liquid 1,1,1-Trifluoroethane (HFC-143a) and Pentafluoroethane (HFC-125)

“…HFC-143a is mainly used as a component in refrigeration fluid blends R404A [which is a mixture of (HFC-125 + HFC-134a + HFC-143a)] and R507 [which is a mixture of (HFC-125 + HFC-143a)]. 1,2 The development of correlation schemes for the viscosity of these mixtures either requires or at least is facilitated by the existence of data for the viscosity of their pure components. However, for HFC-143a, no viscosity measurements could be found in the literature for the compressed liquid region.…”

“…Although thermophysical property data for these substances should, in principle, be required to accomplish such replacement, a literature survey shows that most of the published thermophysical property data on HFCs concern a limited selection of those fluids, like 1,1,1,2-tetrafluoroethane (HFC-134a) and 1,1-difluoroethane (HFC-152a), while only a few measurements for other refrigerants, such as 1,1,1-trifluoroethane (HFC-143a), can be found, often covering modest ranges of thermodynamic conditions. HFC-143a is mainly used as a component in refrigeration fluid blends R404A [which is a mixture of (HFC-125 + HFC-134a + HFC-143a)] and R507 [which is a mixture of (HFC-125 + HFC-143a)]. , The development of correlation schemes for the viscosity of these mixtures either requires or at least is facilitated by the existence of data for the viscosity of their pure components.

Repurposing of F-gases: challenges and opportunities in fluorine chemistry

“…18,64 1,1,1-Trifluoroethane (HFC-143a) is used in a variety of refrigerant blends, mainly R-404A. 29,34,36,66,67 It was avoided as a pure refrigerant due to its high GWP 100 of 5810 and because it is also considered mildly flammable. 22,34,59,68 Recent research has looked at the critical properties of a binary mixture of HFC-143a and E-HFO-1234ze as an alternative refrigerant and supercritical solvent, due to the low critical temperature and high chemical stability of HFC-143a.…”

Experimental Determination of Gas-Liquid Interfacial Tension for POE ISO 10/R-134a Mixtures Using the Maximum Bubble Pressure Method

“…As mentioned earlier, understanding the interfacial tension of refrigerant-lubricant mixtures is crucial in various engineering applications. However, the majority of studies available in the literature focus on pure refrigerants and their mixtures [32][33][34][35][36][37][38][39][40][41][42]. Although research on the interfacial tension of lubricating oils and lubricant-refrigerant mixtures is limited, there has been a noticeable increase in such studies in recent years.…”
