Mollier diagram enthalpy
Web9 dec. 2024 · The Mollier diagram, also called the enthalpy (h) – entropy (s) chart or h-s chart, is a graphical representation of thermodynamic properties of materials. In general, it is a relationship between enthalpy (measure of the energy of a thermodynamic system), air temperature, and moisture content. Mollier Diagram Origins. Richard Mollier created ...

(Adapted from Canjar, L.N. and Manning, F.S., … An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. It shows enthalpy Meer weergeven The diagram was created in 1904, when Richard Mollier plotted the total heat H against entropy S.
