What kind of refrigerant does a Honda Accord use?
If your vehicle was originally charged with R12 refrigerant, for example, the oil type specified, ‘mineral’, will not apply. Additionally, General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, TechChoice now indicates PAG 46 (P46D) oil for those vehicles.
How to calculate the PSIA of Freon 134a?
s = Velocity of sound in ft/sec The gas constant, R = 10.732 (psia)(ft3)/(°R)(lb-mole) for Freon™ 134a, R = 0.1052 (psia)(ft3)/lb·°R One atmosphere = 14.696 psia Conversion factor from work units to heat units: J = 0.185053 Btu/lb = (psia·ft3)/lb·J Reference point for enthalpy and entropy: h
