Material Detail

A pedagogical and open-access simulation workbench designed for building science, mechanical engineering, and energy management curricula. Models seasonal air-source heat pump economics and thermodynamic performance under DOE 10 CFR Part 430 Appendix M1 (0.50 in. w.c. external static pressure) and AHRI 210/240-2023 rating conditions. Evaluates non-linear sub-freezing Coefficient of Performance (COP) decay (+47°F to -15°F), thermal balance point cross-overs, auxiliary electric resistance heat strip staging, and fuel parity break-even electricity rates against natural gas, propane, and fuel oil.
