Material Detail

HVACLogic is an open-access, deterministic engineering simulation suite developed for mechanical engineering educators, HVACR technicians, and building energy auditors. Grounded in peer-reviewed standards (ASHRAE Fundamentals, ACCA Manuals J/D/S, AHRI 210/240, and DOE energy codes), the suite provides rigorous, transparent computational engines replacing opaque rules of thumb.

Core modeling modules include:1. Whole-building sensible and latent heat load calculations grounded in ACCA Manual J and ASHRAE design weather data.2. Cold-climate heat pump low-ambient COP degradation kinetics, variable-capacity inverter derating, and electric resistance balance-point solving.3. SEER2, EER, and HSPF2 seasonal equipment efficiency analysis incorporating ambient dry-bulb and wet-bulb psychrometric dependencies.4. Duct system hydraulic static pressure loss calculations combining implicit Colebrook-White friction factor iterations with equivalent length (TEL) fittings and CFM airflow balancing.5. Thermodynamic psychrometric state solvers implementing ASHRAE Hyland-Wexler moist air equations with exact elevation and barometric pressure corrections.

All calculations run 100% client-side with full formula transparency, live interactive vector visualizers, zero advertising, and zero data-harvesting or database tracking.
