摘要: Energy and exergy analysis is employed to compare the relative thermodynamic performance of Air Source Heat Pumps (ASHP) with that micro Combined Power (mCHP) units. The effect varying heat power demand ratio considered in order provide insights regarding their merits both now for a 2020 scenario. Exergy can be give an indication level irreversibility system theoretical potential improvement; continued development these systems will inevitably reduce irreversibility, improving efficiency. It shown whilst there scope improvements efficiency ASHP mCHP systems, have different effects on overall delivered. For CHP, higher would necessary whereas units are possible across range ratios therefore energy gains may achieved below 1:1.5.
