Abstract According to the definition of exergy-based efficient ecological-function (EBEEF) which is proposed as product (EF) and coefficient performance (COP) in previous literature, this paper applies EBEEF analyze optimize endoreversible Carnot heat-pumps (ECHPs). Via ECHP cycle model established expression for deduced, relationships among heating load (HTL) COP are researched, comparison working at maximum EF conditions performed. Results show that HTL parabolic like ones design points larger should be selected designing heat pumps. When taken primary objective, optimized can improve its reduce entropy-generation-rate by sacrificing a small amount HTL. The not only considers trade-off between entropy-generation-rate, but also COP.

Abstract Based on the definition of exergy-based efficient ecological-function (EEF) proposed in existing literature, which is product energy conversion coefficient-of-performance ( ɛ ) and E ), this paper will introduce EEF into performance optimization for Carnot refrigerator cycle. Via endoreversible model established previous expression derived based finite-time thermodynamic theory, relationships dimensionless versus cooling load R are studied, differences cycles at maximum EEF, , cooling-load conditions compared. The results demonstrate that parabolic-like ones; actual design, should be designed larger points. When taken as optimization-objective, although decreases slightly, increased, entropy-generation-rate σ greatly decreased, so does not only reflect compromise between but also .
