Psychrosi: Thermexcel Programme

References (select examples to add in final manuscript)

The programme is a specialized Excel-based software tool designed for HVAC engineers, researchers, and building designers to perform precise psychrometric calculations . The name "PsychroSI" is derived from psychrometrics (the study of moist air properties) and SI (International System of Units), though the software is often available in versions supporting US units as well. Core Functionality of PsychroSI

The program is a specialized calculation tool designed for Excel that focuses on the psychrometric properties of humid air. In the professional world of HVAC engineering, it acts as a digital "brain" for sizing and optimizing air treatment systems.

ThermExcel's PsychroSI is built as an Excel-based tool , making it highly accessible for professionals already using spreadsheets for engineering.

The is an invaluable tool for any HVAC professional looking to speed up their design processes while maintaining high accuracy. By combining the power of VBA with the versatility of Excel, it simplifies the complex task of psychrometric calculation and air handling analysis.

The engineering challenge isn't making it cold; it is and managing condensation . References (select examples to add in final manuscript)

Unlike static charts where manual estimation introduces human error, PsychroSI resolves thermodynamic equations by . This programming methodology yields a high accuracy threshold, keeping the maximum margin of error near 0.1°C . Advanced Air Treatment Processes

Because the program is built directly as a macro-enabled workbook for Microsoft Excel, it avoids the learning curve associated with standalone proprietary CAD/CAE tools.

: It simulates the mixing of two air streams (e.g., fresh outdoor air and recirculated return air), determining the resulting state point. In the professional world of HVAC engineering, it
