In other case, intentional inhalation of a commercial air-dusting agent containing HFC-134a led to severe orofacial and digital frostbite. ANIMAL STUDIES: HFC- 134a can induce cardiac sensitization in dogs at levels of 80,000 ppm (8% v/v) and higher following exogenous epinephrine challenge. In the rat repeated exposure to 50,000 ppm HFC- 134a Since January 1, 2021, a number of high GWP refrigerants have been banned from use in certain new products, including R404A, R134a, R407C and R410A. R404A and R507A are widely used for high GWP refrigerant, since 2021, will be banned for use in food retail refrigeration equipment new production, at the same time, since January 1, 2023, the properties of HFC-134a to those of CFC-12, an intensive support from the refrigerant and air-conditioning industry has given to the refrigerant HFC-134a as a potential replacement for CFC-12. On the other hand, even though there isn t much difference in properties between these two refrigerants, the overall system performance may be affected HCFC-22 (CHClF 2) and HFC-134a (CH 2 FCF 3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. We find pronounced seasonal variations of global emissions for these two major refrigerants The restriction of HFC-134a will occur under a broader prohibition of any substances with a Global Warming Potential (GWP) higher than 150 in the MVAC sector. HFC-134a will no longer be allowed in nonroad vehicles as of January 1, 2028. Servicing of existing vehicles using HFC-134a with HFC-134a will not be impacted and will continue to be allowed. Refrigerant (R-134a) Freon™ 134a (R-134a) in Chillers Product Information Introduction Because of the phaseout of chlorofluorocarbon (CFC) refrigerants, environmentally acceptable replacements have been commercialized for use in new chillers and in chillers originally designed for use with CFCs. The hydrofluorocarbon (HFC) 134a. Freon™ 134a—An Environmentally Acceptable Alternative Freon™ 134a does not contain chlorine; therefore, it has an ozone depletion potential (ODP) of zero. Listed below are all generic and Chemours trade names: • Hydrofluorocarbon-134a • Freon™ 134a • HFA-134a • Freon™ 134a • Freon™ 134a (Auto) What does HFC-134a smell like? HFC-134a is a nonflammable, colorless gas or liquified gas with a faint ethereal odor. The odor, characterized as weak and nonirritating (Shulman and Sadove 1967), may not be noticeable for most individuals and thus will not serve as a warning property. How big is the high side service port on an R134A? 2011-04-12. Automotive AC System Oil Migration HFO-1234yf Vs. R134a 2011-01-1173. 1. As global automotive manufacturers prepare for the introduction of HFO-1234yf as the low Global Warming Potential (GWP) refrigerant solution in Europe and North America concerns over compressor durability due to oil migration still remain.
