Īlternatively - if the dry bulb temperature is 19 o C and the wet bulb temperature is 12 o C - the state of the air can be visualized in the Mollier chart like:įrom the chart we can see that the enthalpy of the air is approximately 33 kJ/kg and the specific humidity is approximately 0.0056 kg/kg. The specific humidity is approximately 0.0076 kg/kg. The wet bulb temperature is approximately 14.5 o C. The state of air with dry bulb temperature 21 o C and relative humidity 50% is indicated in the Moliier chart below:įrom the Mollier chart the enthalpy of the moist air is approximately 40 kJ/kg. Transform between Mollier diagram and psychrometric chart.
The Mollier diagram is a variant of the psychrometric chart. 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. Air is a mixture of mostly oxygen, nitrogen and water vapor.
