What is R134a refrigerant?
R134a Refrigerant is a common refrigerant that is used in many air conditioning applications, usually packaged in blue colour cylinders. Due to the nature of R134a properties which is of a HFC (hydrofluorocarbon) refrigerant, it does not have any ozone depletion potential and has little greenhouse effect.
What chemicals are in R134a?
Coming from the HFC (hydrofluorocarbons) family of refrigerants, R134a is also known as tetrafluoroethane (CH2FCF3) consisting of two carbon atoms, 2 hydrogen atoms and 4 fluorine atoms.
What is the chemical formula of R134a?
CH2FCF31,1,1,2-Tetrafluoroethane / Formula
is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. R-134a has the formula CH2FCF3.
Is R134a a hazardous material?
Continued breathing of high concentrations of R134a vapours may produce cardiac irregularities, unconsciousness and death. Chemical hazards R134a vapours decompose when exposed to high temperatures with the formation of toxic and irritating compounds such as hydrofluoric acid, carbon monoxide and carbonyl fluoride.
What are the properties of R134a?
R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant….Properties of R-134a.

What is the running pressure of 134a?
For the normal running pressure in an R134A system, the coil should run at 22 pounds per square inch at the lowest temperature, 45−20 = 25 degrees Fahrenheit. Similarly, at the highest temperature, 60−20 = 40 degrees Fahrenheit, the coil should run at 57 psi.
At what pressure is R134A liquid?
The pressure of R134A at 1.7 °Celsius is 30.4 psig and is highlighted in the chart.

Can R134a explode?
Under normal conditions, R134a is a non-flammable gas but exhibits an explosion range at higher oxygen percentages than those in air. At increased temperatures or pressures, R134a also has an explosion range in air, i.e. without any higher oxygen percentage.
At what pressure is R134a liquid?
What is the suction and discharge pressure for R134A?
The normal running pressure of R134A is between 22 and 57 psi.
