Analysis and calculation of exergy in a refrigeration system

Niu Guo

Abstract

First,exergy equation of steady state flow condition is used to analyze exergy equilibriums of all main equipment in a single compression refrigeration system.Then,exergy loss expressions of all main equipment and exergy efficiency expressions of refrigeration system are derived,and relative factors that affect exergy loss are analyzed and some measures are put forward to reduce exergy loss.Finally.exergy loss of a practical refrigeration system is calculated,and the weak links and improvement direction are pointed out.
