The is an essential tool for any mechanical engineer working in the design of HVAC systems in Greece. By offering a robust, accurate, and comprehensive solution for heating and cooling load calculation, it ensures that buildings are designed for maximum energy efficiency, comfort, and compliance with modern standards.
Beyond simple state calculations, PsychroSI includes specialized modules for common HVAC engineering tasks: thermexcel programme psychrosi
: Analyze the resulting properties of two air streams mixing (e.g., fresh outdoor air and recirculated indoor air). Cooling and Dehumidification
PsychroSI (which is sometimes loosely referred to as the “thermexcel programme psychrosi” or “thermexcel programme psychrosi logiciel” in online searches) is the dedicated psychrometric calculation module of the ThermExcel suite. Its main task is to compute the thermodynamic properties of humid air under a wide variety of conditions. The programme can model almost any humid‑air process, including:
is an indispensable tool for anyone working with moist air calculations. By combining the power of Excel with comprehensive psychrometric formulas, it offers a fast, accurate, and efficient way to analyze air handling systems and environmental processes. Whether you are performing quick checks or detailed project designs, PsychroSI delivers reliable results for the modern HVAC professional. To lock in the exact thermodynamic state of
: PsychroSI installs a tailored command toolbar inside Excel to launch macro-commands, calculation panels, and data dialogs.
Because it is built on Microsoft Excel , you can easily copy, paste, and integrate the calculation results directly into your engineering reports and design documents.

It focuses specifically on the needs of HVAC engineers dealing with moist air and air handling. Typical Applications
Steam injection into an air stream is modelled as a constant‑temperature process. The dry air enters the humidifier, gains moisture, and leaves at practically the same dry‑bulb temperature (any slight heating is negligible and is ignored). This calculation is essential for maintaining proper humidity levels in museums, archives, cleanrooms, and some commercial buildings.
The ThermExcel programme for psychroisis has numerous applications in various fields, including:
: The program includes an integrated library of climatic data used for dimensioning air-conditioning installations. 3. Step-by-Step Calculation Guide
It handles the complex calculations involved in mixing two separate airstreams, determining the resulting state point.
