Free and printable examples of Mollier diagrams are available in the following images. The Mollier diagram is a graphic representation of the relationship between air temperature, moisture content, and enthalpy. This diagram is a basic design tool for building engineers and designers. The first diagram below is the enthalpy Mollier diagram.
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. On the diagram, lines of constant pressure, constant temperature, and volume are plotted, so in a two-phase region, the lines of constant pressure and temperature coincide. Thus, coordinates on the diagram represent entropy and heat. To be more precise, take a look at the following diagram below.
A vertical line in the h–s chart represents an isentropic process. Lines of constant dryness fraction (x), sometimes called the quality, are drawn in the wet region and lines of constant temperature are drawn in the superheated region. X gives the fraction of gaseous substance in the wet region, the remainder being colloidal liquid droplets. Above the heavy line, the temperature is above the boiling point, and the dry substance is gas only.
