Hi I am planning on taking the PE Exam this October. I have been practicing refrigeration cycle problems and was wondering if the brain trust herein might have some advice. The refrigerant charts in the study guides and texts I am using are hard to read.....challenging or frustrating to read enthalpy values. Hard to follow constant entropy lines too.

Any thoughts or advice on a good text (with larger scale) refridgerant diagrams.....or anything download-able from the web?
