Hi all new here, I have been doing some research on early refrigeration development, and it seems I have some confusion as to how exactly the Ph diagram got referred to a Mollier Diagram when it seems originally Richard Mollier developed it for psychometric processes? I for one did not know that till recently and only referred to Ph diagrams as Mollier diagrams yet it turns out the term applies to both Ph and Psych diagrams, guess the reason for change to Ph diagram? Anycase just thought I would ask the question I searched for answers but have found nothing as yet.

The same in Belgium, many use the name Mollier for both charts.
In my classes, I make a difference between a log p/h and a Mollier chart. I tell the students that it is not he same chart.
