PsychroSI is a comprehensive calculation tool that, based on just two known parameters of humid air (such as dry temperature and relative humidity), can automatically calculate all other critical psychrometric properties. Its core capabilities are centered on predicting the behavior of air as it undergoes various thermodynamic processes.

The software utilizes iterative mathematical solvers to calculate the complete state point of air. By providing , PsychroSI instantly computes all other thermodynamic parameters with a margin of error within 0.1°C . Users can define an atmospheric air state using any of the following input pairs: Dry Bulb Temperature ( Tdbcap T sub d b end-sub ) and Relative Humidity ( RHcap R cap H ) Dry Bulb Temperature ( Tdbcap T sub d b end-sub ) and Wet Bulb Temperature ( Twbcap T sub w b end-sub ) Dry Bulb Temperature ( Tdbcap T sub d b end-sub ) and Specific Humidity ( / Moisture Content) Dry Bulb Temperature ( Tdbcap T sub d b end-sub ) and Enthalpy ( ) Relative Humidity ( RHcap R cap H ) and Specific Humidity ( ) Specific Humidity ( ) and Enthalpy ( ) Key Calculated Outputs

: It specifically calculates isothermal humidification via steam injection, accounting for the slight temperature changes that occur during vaporization. thermexcel programme psychrosi

The dew point and specific humidity remain completely constant. Relative humidity drops significantly.

Determining the effectiveness of heating/cooling coils.

By plotting the Outside Air point and the Supply Air point, Thermexcel helps you visualize the process line. You can immediately see if you are crossing the saturation line (which would imply condensation/fogging) and calculate the exact energy difference ($\Delta h$) required for the coil. programs, sizing, piping, HVAC, heating, air

Microsoft Excel is widely used across business, science, and industry, but few realise that Excel can be programmed to perform almost any conceivable task and automate repetitive work. ThermExcel was created precisely to unlock this potential. The platform offers a suite of specialised modules – DevExcel for cost estimating, AeroDuct for duct sizing, HydroTherm for hydronic networks, and, central to this article, for psychrometric calculations. All of these are conceived to be readymade, logically laid‑out workbooks that require the minimum amount of manual data entry while still giving the user full control.

Specialized module for calculating indoor pool thermal losses, evaporation rates, and required ventilation.

The ThermExcel programme for psychroisis is based on fundamental thermodynamic principles and psychrometric concepts. The programme uses the following equations and relationships: The dew point and specific humidity remain completely

Thermexcel does directly model evaporative pads (direct evaporative cooling). It models cooling coils only. For indirect evaporative cooling, a secondary air stream can be defined, but it is not psychrometrically coupled.

For psychrosi, the SHR is typically between 0.6 and 0.8, indicating that 20–40% of the coil’s capacity is dedicated to dehumidification (latent cooling).
