Mollier diagram

A Mollier diagram, also known as an enthalpy-entropy chart, is a visual tool used in thermodynamics to understand how water vapor behaves in heating, cooling, and compression processes. It plots properties like temperature, pressure, and humidity to help visualize phase changes and energy transfer in systems like air conditioning and steam turbines. Engineers use it to determine the energy needed for processes such as humidifying, dehumidifying, or cooling air, making complex calculations more intuitive and efficient in designing and analyzing thermal systems.
