What is saturation temperature R134A?
R134a – TetraFlouroEthane Saturation Properties – Temperature Table (-40°C – 20°C)
| Temp | Pressure | enthalpy (kJ/kg) |
|---|---|---|
| -40 | 51.2 | 225.86 |
| -36 | 62.9 | 223.35 |
| -32 | 76.7 | 220.81 |
| -28 | 92.7 | 218.23 |
What temperature does R134A boil at?
-15.34°F (-26.3°C)1,1,1,2-Tetrafluoroethane / Boiling point
What is the vapor pressure of R134A?
19 psi
Although the vapor pressure of Freon™ 134a is almost the same as that of CFC-12 at 70 °F (20 °C), its vapor pressure at 130 °F (54 °C) exceeds the pressure limit of a U.S. Department of Transportation (DOT) 2Q aerosol container by about 1 atmosphere, i.e., 19 psi.
What is the evaporation temperature of R134a at 0 psig?
-15°Fahrenheit
For example, the evaporation temperature of R134a at 0 psi is -15°Fahrenheit.
At what particular temperature do the R134a change its state?
R134a has a boiling point of -15.34 degree Fahrenheit or -26.3 degree Celsius that makes it exist in gas form when exposed to environment. This is a desired property as the boiling point of a refrigerant should be below the target temperature. iii.
What does the A stand for in R134a?
an isomer
R134a.. Here “a” is used to denote that it is an isomer. R134 and R134a have same chemical formula and atomic weight but different chemical structures. R134 has NBP of about -19 C whereas R134a has a NBP of about -26C.
Can you mix synthetic R134a with non synthetic?
A: No can do. The system will have to be evacuated properly, to remove any oil and any water or humidity that got in. Then you can add the correct amount of oil and refrigerant, in this case R134a.
What pressure should a 134a freezer run at?
If 134 is right, your suction side will be at about 7 in. hg. ( in a vacuum)when at -20, and will start about 10 – 15 psig if box is about 50-60 F.
