Mixing two air streams – for instance, outdoor fresh air with return air – is a fundamental HVAC operation. PsychroSI allows the user to enter the dry‑bulb temperature and moisture content of each stream, and then calculates the final mixed‑air state. This is indispensable for determining the appropriate pre‑heating, cooling, or humidification needed before the mixed air enters the conditioning equipment.
There are dozens of psychrometric calculators on the market, so why stick with Thermexcel? Here are three key reasons:
CETIAT has validated Thermexcel against experimental data for dehumidifying coils within ±5% for capacity and ±10% for outlet RH, provided: thermexcel programme psychrosi
) : The total thermal energy contained per kilogram of dry air (expressed in kJ/kg).
: Vital metrics used to accurately convert volumetric airflows ( ) into mass flow rates ( ) for sizing fans and ductwork. Mixing two air streams – for instance, outdoor
In conclusion, the ThermExcel program represents a significant innovation in the field of psychosynthesis, offering a holistic and integrative approach to personal growth and self-discovery. By providing a deeper understanding of the human personality and promoting emotional, mental, and spiritual well-being, the program has the potential to support individuals in their journey towards self-realization and wholeness.

The project was approved within the week. For the guests at the aquatic center, the air felt perfectly crisp and clear. They didn't see the complex VBA code or the psychrometric tables—they just felt the invisible hand of a perfectly programmed environment.
: Calculates the resultant state point when two separate air streams (such as recirculated return air and fresh outdoor air) combine.
Le cœur du programme repose sur la détermination complète de l'état de l'air humide à partir de variables minimales. 1. Résolution par itérations successives
Most HVAC load calculations are done in Excel. Thermexcel is not a separate app you have to alt-tab to; it lives right inside your spreadsheet. This allows you to link psychrometric outputs directly to your load calculation cells. If you change the outside air temperature, the enthalpy updates automatically in your calculation sheet.
