You can download our program Mollier Sketcher here.
In order to clearly describe and understand how air changes state when we cool and heat it, we use a Mollier diagram. The Mollier diagram uses different scales and curves to illustrate the state of the air.
The program has no restrictions or predefined processes so it is up to you to determine which process is physically possible. The program is intended for users with previous experience of Mollier diagrams.
