Abstract: A new non-dimensional performance parameter, exergy transfer units number, which is in conjunction with exergy transfer effectiveness, is proposed to evaluate exergy transfer performance of heat exchangers operating above/below the surrounding temperature. The analytical expressions of exergy transfer units number are derived, and the relationship between exergy transfer effectiveness and exergy/heat transfer units number is further established. The impacts of heat transfer units number, the ratio of heat capacity of cold fluids to that of hot fluids and flow patterns on exergy transfer units number, as well as the dependence of exergy transfer units number on exergy transfer effectiveness, are systematically discussed.
