Pressor & Temperature Relation Chart In Air-Conditioning System

R-12 & R-22 are no longer approved in the US. At one time Dupont provided tables and charts of the thermodynamic properties of both of these obsolete products on request.

The manufacturers of the current replacement product MAY have such information available. Ask your supplier.

Any HVAC supply house will have the charts you need - I've got one here on my desk on the back of a notepad that I got free @ Johnstone Supply. Contrary to my colleague's previous comment, it is merely the manufacture of new supplies of those refrigerants which is banned under current (and, to my mind, sorely misguided) regulation, the use of R22 is industry-wide, and will remain so for many years to come.

Please do us the favor of running spell check so that we may understand. In this case I have done so for you. I hope this clarifies your question so that it may be more easily answered. Your welcome.

Presser & Temperature Relation chart In Air-condo. System.

I would like to know the Refrigerant Presser and temperature Cooperation Table for R22, & R12,Refrigerant. To be more specific what is the discharge presser for a healthy Refrigeration system and it's back presser in that state If we consider Ambient temp. is 38 deg. centigrade,and humidity is 55/60 %.

If you find my question is funny then I am sorry, but I really want to get answer of my question.....

Thanks.

Dear Friend,

Try the book " Refrigeration and Air Conditioning" by ALTHOUSE. The charts there are not as large but they are as good for approximations.
