The boiling point of R-12 is given as -29.8oC.
Now replaced by R-134A which had a boiling point of -26.3oC.
Some oils and rubbers previously used with R-12 may not be compatible with R-134A.
It is 87.3 K.
-increase the temperature of the super heated steam -lowering the condensing pressure -increasing the boiler pressure (Reheating, regeneration...)
When the maximum pressure of the refrigerant is achieved in the condensor and the maximum temperature differential is acheived between the condensor coil and the surrounding medium. (air, water, or other)
I believe it is condensing.
Its still water.
R-12..........
It is 87.3 K.
The condensing point is the particular temperature at which a substance changes state from gas to liquid. The condensing point of water is 100 deg. C or 212 deg. F.
12
phosphoric acid
Water is condensed on a cool surface.
As rule of the thumb, refrigerant condensing temperature should between 1-2 degreeC higher than the exiting water temperature, this temperature difference is technically called condensing temperature approach. I f the approach is below or above means, system is flooded with refrigerant or system got starve. Above method is also effective in determining if the condenser shell needs maintenance for sclale, sludge build up removal. I am refrigeration mechanic.
depends but usuaally around 32 deg c or 200 psi
75 or 80
The temperature varies with its pressure. If pressure high the condensing temperature also high. please be more specific, can someone please provide more specifics to this?
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.
