Psychrometric chart is a fundamental calculation for determining air parameters in heating, ventilation, and air conditioning systems.

For example, it can be used to determine the capacity for cooling or heating, the flow of recirculated or external air, the flow of moisture for humidification, to avoid the formation of condensation, etc.
Calculation of all necessary processes
  • Heating.
  • Cooling.
  • Mixing.
  • Angle factor.
  • Steam humidification.
  • Adiabatic humidification.
  • Adiabatic dehumidification.
  • User process.
Two types of chart
The chart can be displayed as a Mollier chart or a Ramzin chart.
Calculation of integrated processes

You can calculate processes not only individually, but also combine several processes into a common calculation.

For example, external air entering the AHU is first heated, then mixed with recirculated air, then humidified.
Detailed reports

The calculation report can be saved to an Excel file with data from all processes and points.

The chart can be saved as a PNG file.
Multiple calculation parameters
  • Start point by temperature and relative humidity, specific humidity, enthalpy.
  • Air flow can be volume or mass.
  • Heating and cooling by capacity or final temperature.
  • Steam humidification by moisture exudation or final relative humidity, specific humidity.
  • Adiabatic humidification by moisture exudation or final temperature, relative humidity, specific humidity.
  • Adiabatic dehumidification by moisture absorption or final relative humidity, specific humidity.
  • Change of the length of the angle coefficient process by temperature.
