Material Detail

An open-access empirical benchmark dataset and thermodynamic simulation workbench modeling air-source heat pump (ASHP) Coefficient of Performance (COP) decay, sensible heating capacity retention, and electrical power demand across sub-freezing outdoor ambient temperatures (+47°F down to -15°F / -26.1°C).

The material evaluates performance under AHRI Standard 210/240-2023 and DOE 10 CFR Part 430 Appendix M1 test protocols. Students and engineering researchers can analyze vapor-compression Carnot limits, refrigeration enthalpy drops, defrost cycle penalties at +35°F, and the operational economics of cold-climate enhanced vapor injection (ccASHP with EVI) vs. auxiliary electric resistance heat strip staging.
