Read the air density by following the slanting orange lines in the diagram. The Mollier diagram is a variant of the psychrometric chart. Specific humidity from 0 to 250 gkg.

This diagram is widely used in mechanical engineering and HVAC technology and plots the Temperature versus the Absolute HumidityThe chart is is combined with the Relative Humidity lines and the Enthalpy to calculate the change in total internal energy. The result of the student Bjorn Es looks great. Kg h x adiabatic conditions for the dryer h h mmxx m xx kgkg m hh kJkg Heating coi.

Also service technician make good use of the Mollier diagram while installing or maintaining installations that cool air heat air steam refrigerate etc. An easy-to-read tool still in use today. Download Mollier Sketcher 21b.

Transform between Mollier diagram and psychrometric chart. Zustandsdiagramm für feuchte Luft als Web App. Ductwork specific pressure loss calculation.

The Mollier diagram is used to calculate the amount of water one needs to add in order to obtain a desired cooling effect or a desired humidity level in a room. The Mollier h x diagram formerly ix diagram enthalpy-water load diagram makes it possible to describe changes in the state of humid air through heating humidification dehumidification cooling and mixing of different amounts of air. 100 relative humidity line in the Mollier diagram.

Understanding the IXHX diagram The IXHX or psychrometric diagram the Mollier diagram is one of the most useful tools when designing an air humidifying system. H-X diagram Mollier Pre-adjustments can be made in the following ranges. A detailed description and download available at wwwhx-diagrammde.
