Hey guys.

Sorry to ask this, but I have been googling around and searching this afternoon, but I am in dire need of a pt chart for r22. Its urgent, that's why I am asking. Can anyone help? It needs to be quite big. I tried to make one, but I don't think its correct.

Regards
Mike

I should have been more specific. We work in Kpa / Bar and when I did the conversion, I had a boiling point of 40c @ 3.4kpa. Is this right? If it is, all my problems are sorted.

r22 saturation pressure at +40C is 15.3Bara (1530KPa), saturation pressure at -40C is 1.05Bara (105KPa) :)
