Based on irreversible four-temperature-level (FTL) cycle models, an ecological criterion function of absorption
heat pump (AHP) plants is proposed. This function can attain a compromise in inter restricted relations between
exergy output and exergy loss of AHP plants. Relations among ecological function, coefficient of performance
(COP), heating load, exergy output and exergy loss, and various loss factors are derived. Simplified relations are
derived when various irreversibility factors can be ignored. The exergy-based ecological characteristics are
analyzed through numerical examples. The results can provide some new suggestions about parameter selection
for practical AHP plants.
