But let’s face it: manually calculating wet-bulb temperatures, enthalpy, and dew points using psychrometric formulas is tedious and prone to error. Enter , a suite of Excel-based tools that has become a staple for engineers. Today, we are focusing on one of its most powerful modules: the Psychrosi (Psychrometric) Program .
: Quantification de la vapeur d'eau libérée selon la température de l'eau, l'agitation, le taux d'hygrométrie ambiant et la vitesse du vent au-dessus du plan d'eau.
To lock in the exact thermodynamic state of moist air, a user only needs to provide . The program instantly solves the remaining variables using thermodynamic iterations: Dry Bulb Temperature ( Tscap T sub s ) & Relative Humidity ( HRcap H cap R Dry Bulb Temperature ( Tscap T sub s ) & Wet Bulb Temperature ( Thcap T sub h Dry Bulb Temperature ( Tscap T sub s ) & Specific Humidity ( Dry Bulb Temperature ( Tscap T sub s ) & Total Enthalpy ( Relative Humidity ( HRcap H cap R ) & Specific Humidity ( Specific Humidity ( ) & Total Enthalpy ( 2.

Evaluation of evaporation and heat requirements for pool environments.
There are dozens of psychrometric calculators on the market, so why stick with Thermexcel? Here are three key reasons: The key input for psychrosi is the or
To avoid condensation, you need insulation. But how thick? Too little, and you get water damage. Too much, and you waste money. Using the ThermExcel "Cold Insulation" module, you input the psychrosi target (e.g., maintain -10°C for a freezer floor). The programme calculates the exact insulation thickness to keep the outer surface temperature above the dew point.

PsychroSI’s iterative wet‑bulb algorithm yields errors of at most 0.1 °C, which is well within the uncertainty of most field measurements. The programme uses standard psychrometric relationships (e.g. the Magnus‑Tetens approximation for vapour pressure) and assumes that the total pressure is standard atmospheric pressure, unless a local barometric correction is manually applied. For most HVAC design work, this level of accuracy is perfectly adequate. Enter , a suite of Excel-based tools that
The ThermExcel program has a wide range of applications in various fields, including:
