A critical feature for ventilation and AHU (Air Handling Unit) design is the ability to mix two air streams (e.g., outdoor air and return air). allows you to define the state of two airflows (dry temperature, humidity, mass flow rate) and instantly calculates the resulting state and properties of the mixed air. 3. Psychrometric Process Analysis thermexcel programme psychrosi
To model, calculate, and optimize this process, engineers need robust software. Enter —a powerful, Excel-based psychrometric toolkit. This article provides a comprehensive guide to using the ThermExcel programme for psychrosi , covering its theoretical foundations, step-by-step application, and practical benefits.
The PsychroSI module is not just a single calculator; it is a suite of tools designed for specific real-world engineering scenarios. The most notable capabilities include:
: Includes specific thermal calculation tools for swimming pools (heat loss and humidity control) and industrial processes like odor treatment or misting systems for greenhouses. 2. User Interface & Workflow is unforgiving
combined with relative humidity, wet-bulb temperature, specific moisture, or enthalpy. Relative humidity paired with specific moisture. Specific moisture and enthalpy .
: Vital metrics used to accurately convert volumetric airflows ( ) into mass flow rates ( ) for sizing fans and ductwork.
is part of the extensive suite of HVAC and calculation programs developed by ThermExcel . It is essentially a sophisticated calculation program designed to compute the various states of humid air. Because it runs within Microsoft Excel, it provides a familiar interface while leveraging the power of Excel's data analysis capabilities. The program specializes in: Undersize it
: Calculate air properties from pairs such as: Dry Bulb Temperature (DBT) + Relative Humidity (RH) Dry Bulb Temperature + Wet Bulb Temperature (WBT) Specific Moisture + Enthalpy Process Simulation : Model air treatment cycles including:

The program supports the analysis of heating, cooling, humidification, and dehumidification processes.
is an Excel-based application developed by ThermExcel that provides instantaneous psychrometric calculations. Unlike static psychrometric charts, this program allows users to input known parameters—such as dry bulb temperature and relative humidity—to automatically calculate all other properties of humid air.
