Thermexcel Programme Psychrosi May 2026

• Thermexcel is a known software tool developed by the French company CETIAT (Centre Technique des Industries Aérauliques et Thermiques). It is a thermal calculation software used for heat exchanger design, particularly for finned-tube heat exchangers (air coolers, condensers, evaporators) in HVAC&R (Heating, Ventilation, Air Conditioning, and Refrigeration).
• Psychrosi does not correspond to a standard English or French technical term. However, it resembles psychrometry (the study of moist air properties) — in French, psychrométrie. It might be a misspelling of psychrométrie or possibly a brand name / internal code.

1. Psychrometric Calculations: The programme allows users to perform various psychrometric calculations, including the determination of air properties such as temperature, humidity, enthalpy, and entropy.
2. Psychrometric Charts: ThermExcel provides a range of psychrometric charts, including the psychrometric chart, which is a graphical representation of the relationships between the thermodynamic properties of air and water vapor mixtures.
3. HVAC System Design: The programme can be used to design and optimize HVAC systems, including heating, cooling, and ventilation systems.
4. Moisture and Heat Transfer Calculations: ThermExcel allows users to calculate moisture and heat transfer rates in various systems, including drying and cooling systems.
5. Air Quality Calculations: The programme can be used to calculate air quality parameters, including indoor air quality and ventilation rates.

5.2 Evaporative Cooling

Thermexcel does not 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.

program by ThermExcel is an Excel-based tool designed for HVAC engineers to perform complex psychrometric calculations for moist air. It is particularly useful for sizing heating, ventilation, and air conditioning systems, as well as specialized applications like indoor swimming pools. 1.
