摘要
应用稳流系统的火用方程 ,分析了单级蒸气压缩式制冷系统中各主要装置的火用平衡 ,导出了各装置的火用损及制冷系统火用效率的工程计算式 ,并对影响火用损的相关因素进行了分析 ,提出了减小系统主要设备火用损的措施 ,最后对一实际制冷系统的火用损进行了分析计算 。
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.
