Just recently started doing comercial (job forces move) and got myself booked on a coures but that starts September.
Now i would like to start using pt charts now as i can see them being very usefull.
I have downloaded one for the 134a gas (the only one i use) but i cant find any thing on where to take the temp evap, condensor, dryer ect, and does it relate to the high or low side. Any help would be great.

Use the Search button above for 'Mollier Chart'
I'll start you off - scroll down, don't just read the first few posts. Lots of information on here.

Quite a useful Tech Guide on Emmerson's website.
Couldn't get a direct link to it but onto the pre-page.
Cut and paste this onto Google..
emmersonclimate tech guide-april08
The book is the first one one the list and is 5.1MB.

Here it is direct link (http://www.emersonclimate.com/flowcontrols/pdf/Tech%20Guide%20-%20April%2008.pdf)!
Allow some time (depending on your connection speed) to download.

Thanks Nike, I had so many tabs open when I got that downloading I thought I'd use the slow do-it-yourself method :), cheers.

You need to wait a little while, the link goes directly to the download page.
Or follow my instructions as given in post #3.
Try searching for Coolpack there is a utility called Refrigeration Utilities that gives you the option to print out most of the charts you may need plus PH charts aswell.
