1 Production of R11 or CFC-11 was halted by the clean air act on January 1 1996 2 Production of R12 or CFC-12 Dichlorodifluoromethane was halted by the clean air act on January 1 1996 3 R22 or HCFC-22 is a single component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air-conditioning and refrigeration applications in a variety of markets. R-134a is the most common refrigerant found in automobiles today.

It has been in use since the early 1990s and now in 2019 we are beginning to see its popularity wane with the rise of the new HFO refrigerant known as R-1234yf. That being said there are still millions of cars on the road that. 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. It has the formula CH2FCF3 and a boiling point of 263 C 1534 F at atmospheric pressure. This is a non-flammable gas used primarily as a high-temperature refrigerant for domestic refrigeration and automobile air conditioners.

Thermodynamic Properties of Saturated Refrigerant R134a. The R-32 serves to provide the heat capacity R-125 decreases flammability R-134a reduces pressure. R-408A is a zeotropic HCFC blend of R-22 R-125 and R-143a.

It is a substitute for R-502. Its boiling point is 444 C. R-409A is a zeotropic HCFC blend of R-22 R-124 and R-142b.

95C 203F Critical Pressure. 34 bara Auto. The molecule size of R134a is smaller than that of R12 so there was concern that R134a could leak out through the hoses and flare fittings that R12 systems used.

R134a systems operate at higher discharge-side pressures than R12 which can cause compressor seals to leak. Bottom line R134a simply doesnt cool as well as R12. It is similar to boiling water on top of the stove.

The heat must be able to move into the evaporator for it to boil the liquid. Air filters must be clean the fan must be moving the air the coil must be clean and on systems where there is an adjustable refrigerant control it must be correctly applied and installed and adjusted. It has the formula CH2FCF3 and a boiling point of 263 C 1534 F at atmospheric pressure.
