废热溴化锂制冷机可以直接利用烟气废热或化学反应热来驱动进行制冷,因此废热回收的综合利用率比较高。论文对烟气废热驱动废热溴化锂制冷机的热能利用的经济性进行了分析,在烟气废热驱动溴化锂制冷机中,溴化锂制冷机的COP仅仅反映的是溴化锂制冷机本身的性能,不能作为衡量废热溴化锂制冷机废热制冷的效率高低和性能好坏的标准,因此本文采用废热利用率和废热制冷率对烟气废热溴化锂制冷机的废热制冷性能指标,废热制冷率与炯效率分析结果相一致,通过比较发现,二级烟气双效废热驱动废热溴化锂制冷机的废热制冷率最高,炯效率也最高。
Waste heat Lithium bromide refrigerator can directly use flue gas waste heat or chemical reaction heat to drive refrigeration, so the comprehensive utilization of waste heat recovery is relatively high. The paper analyzes the economical efficiency of thermal energy utilization of waste heat lithium bromide refrigerator driven by flue gas waste heat. In the flue gas waste heat driven lithium bromide refrigerator, the COP of lithium bromide refrigerator only reflects the performance of lithium bromide refrigerator itself and can not be used as a measure of waste heat Lithium bromide refrigerator waste heat cooling efficiency and good performance of the standard, so this paper uses waste heat utilization and waste heat cooling rate of flue gas waste heat lithium bromide refrigerator waste heat cooling performance indicators, waste heat cooling rate and Jiong efficiency analysis results are consistent, through It is found that the second stage flue gas double-effect waste heat driven waste heat lithium bromide chiller has the highest waste heat recovery rate and the highest efficiency.
