Why R134a is used as refrigerant?
R134a has fairly good dielectric properties as it has high thermal stability, low boiling point, and chemical inertness against the construction materials used; and is non-toxic and non-flammable. . A dielectric substance in its gaseous state can be used to prevent electric discharges.
Does R134a rise or fall?
Yes is the correct answer. Refrigerant, and in this case I am speaking specifically about R-134a, but it’s typical of refrigerant gases, is heavier than air. Always check with the refrigerant manufacturer, but the chemical composition of R-134a is all the same regardless of the name on the canister.
Is R134a a good refrigerant?
At what temp does R134a boil?
-15.34°F (-26.3°C)
1,1,1,2-Tetrafluoroethane/Boiling point
How do you store R134a refrigerant?
Refrigerant should be stored into a well ventilated area and temperatures should NOT exceed over 125 degrees Fahrenheit. If the temperate becomes too hot pressure can build inside the container which could cause the container to rupture.
What refrigerant is compatible with 134a?
There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744.
