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) 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 Hydrofluorocarbon-134a or 1,1,1,2-Tetrafluoroethane (HFC-134a) has been developed as a replacement for fully halogenated chlorofluorocarbons because, compared with chlorofluorocarbons, its residence time in the atmosphere is shorter and its ozone depleting potential is insignificant. HFC-134a is used in refrigeration and air conditioning systems, as a blowing agent for polyurethane foams, and All vehicles exhibited measurable R-134a leakage over the 2-day diurnal test. Leak rates of R-134a ranged from 0.01 to 0.36 g/day with an average of 0.07+/-0.07 g/day. When combined with leakage associated with vehicle operation, servicing, and disposal we estimate that the lifetime average R-134a emission rate from an AC equipped vehicle is 0. R-404A began seeing usage in 1996 after the phase out of CFC R-502 due to it’s Ozone Depletion Potential. R-404A is a ternary refrigerant blend consisting of the HFC R-125 (forty-four percent), HFC R-143a (fifty-two percent), and HFC R-134a (four percent). R-404A is used across a variety of low and medium temperature applications including Effect of condenser fouling is evaluated on the performance of a vapour compression system with refrigerants HFO1234yf and HFO1234ze as an alternative to HFC134a. The condenser coolant temperature has been varied between 35 and 40°C to evaluate the effect of fouling at different condenser temperatures. A simulation model is developed in EES for computing the results. The results have been Gh3PA. The COP of HFO-1234yf with changing compressor rpm is 1.3–5% lower than HFC-134a, which is in good agreement with the previous work [10] that reported 0–4% lower COP. The conformity of the simulated model for HFC-134a was also checked by Kayanakli and Horuz [23] (Fig. 14).

The government showed disapproval for using HFC-134a in brand-new light-duty vehicles. As per the federal order and for the sake of nature, numerous automobile manufacturers are adopting the transition to the latest, climate-friendly This SAE Standard is to establish the specific minimum equipment requirements for the recovery/recycling of HFC-134a that has been directly removed from, and is intended for reuse in, mobile air-conditioning systems and recovery/recycling and system recharging of recycled or virgin HFC-134a. Pressure - Temperature Chart for HFC-134a Author: US CDC cited at InspectApedia.com Subject: R134 Pressure Temperature Chart Keywords: refrigerant,pressure,temperature,R134,R-134 Created Date: 7/23/2014 8:32:34 PM R-134a is a blend component used in many refrigeration systems. It is also a propellant for aerosol and a blowing agent for extruded polystyrene foams. R-134a replaces the CFC R-12 and in few years will replace the HCFC R-22. The tables attached were developed based on a refrigerant property database (REFPROP 7.0) In general, esters offer excellent solubility with HFC-134a, as shown in Table 5. In addition, many of the esters are not highly sensitive to residual mineral oil concentration (an issue that made retrofits using PAGs difficult). It is recommended that the mineral oil concentration be less than 10% for chilled water applications and less than
