: Temperature drops at a constant specific moisture level ( ) until the air reaches its dew point.
Results are typically presented in tabular format within Excel, which can be exported or printed as professional engineering reports. Resources for Further Implementation
In most air‑conditioning applications, cooling a coil not only lowers the air temperature but also causes condensation on the coil fins, thereby dehumidifying the air. PsychroSI models this by defining three points:
The foundational benefit of PsychroSI is its ability to map an entire thermodynamic state of humid air using . By entering any two properties, the program executes iterative algorithms to resolve all other relevant parameters: Dry Bulb Temperature ( Tdcap T sub d ) & Relative Humidity ( RHcap R cap H ) Dry Bulb Temperature ( Tdcap T sub d ) & Wet Bulb Temperature ( Twcap T sub w ) Dry Bulb Temperature ( Tdcap T sub d ) & Specific Moisture / Humidity Ratio ( ) Dry Bulb Temperature ( Tdcap T sub d ) & Enthalpy ( ) Relative Humidity ( RHcap R cap H ) & Specific Moisture ( ) Specific Moisture ( ) & Enthalpy ( ) Iterative Precision thermexcel programme psychrosi
Includes a library of approximately 265 international weather sites to provide localized climatic parameters for HVAC dimensioning. 4. Software Architecture & Usability
Contrairement au système adiabatique, l'injection de vapeur sèche apporte de l'humidité de manière quasi-isotherme. Bien qu'elle engendre localement de légères variations de température, l'outil calcule précisément les nouvelles coordonnées psychrométriques de l'air traité selon le taux d'hygrométrie cible. Mélanges d'air, réchauffage et traitement des batteries
PsychroSI simulates adiabatic humidification where water is sprayed directly into an unsaturated air stream. Because no external heat is introduced or removed, the sensible heat of the air evaporates the water, along a line of constant enthalpy. : Temperature drops at a constant specific moisture
How to integrate PsychroSI results into other like AeroDuct or HydroTherm.
), which are preferred over fluctuating volumetric flow rates ( ) since air density shifts across temperature ranges. Key Applications and Air Sizing Scenarios 1. Air Mixing and Treatment Sizing (Air Handling Units)
The ThermExcel programme for psychroisis was developed using Excel 2019 and VBA 7. The programme consists of three main modules: PsychroSI models this by defining three points: The
Beyond standard air handling, the "Psychrosi" module includes specific thermal calculations for swimming pools, making it valuable for leisure center engineering projects.
Beyond basic point-state calculations, the PsychroSI suite includes specialized modules for complex HVAC processes:
