The relationship between the psycrometric chart and the Mollier diagram.
Mollier diagram express the same psychrometric properties as a psychrometric chart. Both presentations are very useful when designing air condition systems, drying processes etc.
The process of transforming a Mollier diagram to a psychrometric chart - or vice versa - is shown below.
first - it has to be reflected - flipped - in a vertical mirror
second - it must be rotated 90 degrees
Moist and humid air - psychrometric charts, Mollier diagrams, air-condition temperatures and absolute and relative humidity and moisture content.
Basic air changing state processes - heating, cooling, mixing, humidifying and dehumidifying by adding steam or water - psychometric diagrams and the Mollier charts.
Air can be humidified by adding water or steam.
Relative humidity in moist air can estimated by measuring the dry and wet bulb temperature.

oF to 120 oF.
Dry Bulb, Wet Bulb and Dew Point temperatures can be used to determine the state of humid air.

The change in state wwhen mixing moist air - enthalpy, heat, temperature and specific humidity.
Cooling and dehumidifying processes of moist and humid air - sensible and latent cooling.

The Mollier diagram is a graphic representation of the relationship between air temperature, moisture content and enthalpy - and is a basic design tool for building engineers and designers.
