Thermexcel Programme Psychrosi May 2026

Here is the magic of using ThermExcel for cooling simulations. Because it is spreadsheet-based, you can manually override the "U-values" (thermal transmittance) and see real-time results.

Step 1: Defining the Delta T ThermExcel forces you to look at the difference between the chilled surface and the ambient air. For psychrosi, you usually have a high Delta T (e.g., 35°C ambient vs. 5°C pipe). The program calculates the heat flux into the cold system. thermexcel programme psychrosi

Step 2: The Dew Point Trap The most brilliant feature for psychrosi is the automatic dew point check. When you simulate cooling a surface, ThermExcel checks the surface temperature against the ambient dew point. If the surface is below the dew point? Red flag. The program tells you: "Warning: Condensation risk." Here is the magic of using ThermExcel for

Step 3: Insulation Balancing 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. Unlike expensive proprietary software

Ensure the ThermExcel add-in is activated. You should see custom functions like Psychro, TDew, W, h, and CoilProcess. If not, install the .xlam file following the developer’s instructions.

ThermExcel is not a standalone application but a sophisticated collection of macros, formulas, and psychrometric functions embedded within Microsoft Excel. Developed primarily for HVAC engineers, it offers:

Unlike expensive proprietary software, ThermExcel leverages the universal accessibility of Excel, making professional-grade psychrometric analysis available on any laptop.
