LATEST OP TIONS FOR REPLACING HFC- 134A REFRIGERANT IN MACS 3. 2013 and 201 8—approximately 17%—used HFO-1234yf [. vapor-compression technologies, such as ai. lso. under study for MAC and The thermal performance, non-toxic chemistry and stability are nearly the same between R-1234yf and R-134a. The primary difference between the two is R-1234yf being slightly more flammable. ASHRAE classifies R-1234yf as a “mildly-flammability” fluid (A2L); R-134a carries an A1 safety classification due to its lower flame propagation. It's the same thing so yes. 8. MonMotha. • 4 yr. ago. Two names for the same thing. 3. y_3kcim. • 4 yr. ago. R stands for refrigerant, hfc stands for Hydrofluorocarbons, the chemical makeup of the refrigerant. Genetron 134a. Suva 134a. HFC-134a. is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. R-134a has the formula CH2FCF3. However, industrial grade R134a is mainly used as a refrigerant and fire extinguishing agent. The industrial grade is used in refrigeration and air-conditioning etc, whereas the pharma grade is used as a drug propellant. The plant and machinery, raw material, and the process of production of both the types are same. Refrigerant R134a or HFC-134a was developed to meet these needs. Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems. to use an R 134a compressor with the same displacement as used for R 12. However, to obtain the same refrigerating capacity under LBP conditions, it is necessary to select an R 134a compressor with the next higher displacement to the one used for R 12.

Genetron® 134a is a long-term, environmentally safer, non-ozone depleting substitute. As a refrigerant, it possesses similar energy efficiency and capacity characteristics as R-12 and has an intrinsically low toxicity. A DuPont R-134a refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC F39hIt.
