i understand somewhat the practice of the temp/pressure charts but does the addtion of 30 degrees to ambient temp for the high side pressure for r22 also work the same for other freons? i work with units containing r22, r404a, r502, and r409. and just to make sure i understand completely, can you please explain how to use the temp/pressure chart? and any websites that can benefit would be great. i took a study course but it was limited in information on certain subjects. thanks
