The thermodynamic and physical properties of Freon™ 134a, coupled with its low toxicity, make it a very efficient and safe replacement refrigerant for CFC-12 in many segments of the refrigeration industry, most notably in automotive air conditioning, appliances, small stationary equipment, medium-temperature supermarket cases, and
Refrigerant R134a - Properties - SI Units. 1,1,1,2-Tetrafluoroethane - R-134a - is an inert gas used primarily as a high-temperature refrigerant for domestic refrigeration and automobile air conditioners. Thermodynamic properties of refrigerant R-134a.
1,1,1,2-Tetrafluoroethane (also known as norflurane , R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion ...
Appendix C: Property Tables for R134a. Tables C-1 and C-2 present data for saturated liquid and saturated vapor. Table C-1 is presented information at regular intervals of temperature while Table C-2 is presented at regular intervals of pressure. Table C-3 presents data for superheated vapor over a matrix of temperatures and pressures.
New tables of the thermodynamic properties of HFC-134a have been developed and are presented here. These tables are based on experimental data from the database at the National Institute of Standards and Technology (NIST). Equations have been developed, based on the Modified Benedict-Webb-Rubin (MBWR) equation of state, which
Properties of R-134a refrigerant in SI. The most common R134a refrigerant cylinder and box for its storage and transportation. The net weight of freon R134a in such a cylinder is 13.6 kg.
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)
