The Mollier diagram helps us to clearly describe and understand how air changes state when we cool and heat it. In order to dimension the components in an air handling unit, it is necessary to know the relationship between air temperature and humidity. This is why the Mollier diagram is a part of our identity and forms the core of our daily work.
The Mollier diagram has different scales and curves that illustrate the state of the air, allowing you to see the relationship between air temperature, moisture and heat content.
The Mollier diagram was invented in 1923 by the German Richard Mollier.
