R123Tables Excel Add-In Demo 3.1

R123Tables Excel Add-In Demo by MegaWatSoft Inc. brings refrigerant R-123 property calculations directly into Microsoft Excel, so you can build, audit, and share engineering spreadsheets without leaving your workflow. The add-in exposes easy-to-use worksheet functions that return properties such as enthalpy, entropy, density, specific volume, specific heat, quality, viscosity, and thermal conductivity from common input pairs, accelerating HVAC/R design, analysis, and teaching.

Key features:

• Native Excel functions for R-123 in saturated and single-phase regions (typical inputs include P–T, P–h, T–s, T–x, and more)
• Results suitable for engineering calculations: thermodynamic and transport properties with consistent units
• Flexible unit handling with SI and IP options
• Fast, reliable interpolation designed for smooth integration into formulas, charts, and VBA
• Sample worksheets and a quick-start guide to help you get productive immediately
• Clean installation and ribbon/menu access for discoverability

About the demo:

• Same workflow as the full version, with limits appropriate for evaluation (for example, reduced property ranges, fewer functions, or occasional prompts)
• Intended for testing and learning; not licensed for production or commercial use

Who it’s for:

• HVAC/R engineers, energy analysts, researchers, educators, and students who need dependable R-123 properties inside Excel

By embedding R-123 calculations where you already work, R123Tables Excel Add-In Demo helps reduce manual lookups, minimize transcription errors, and speed up scenario analysis—so you can focus on engineering decisions rather than data gathering.
