重庆某冷热电三联供与江水源热泵复合系统运行分析

摘要

Combined with field measures and test data from third party,analyses the actual operational performance of a combined cooling heating and power system(CCHP)coupled with river watersource heat pump in Chongqing.The measure results show that power generating efficiency,exhaust heat recovery rate and primary energy ratio of CCHP are 35％,52.7％ and 82.3％,respectively.The cooling seasonal energy efficiency ratio and heating seasonal energy efficiency ratio of river water-source heat pump system are 3.85 and 3.97,when running at 55.6％ of cooling load and 89.3％ of heating load,respectively.Compared with actual operational strategy,the energy consumption can be decreased by 39.9％ with design strategy.%结合实测调研与第三方检测数据,对重庆某冷热电三联供复合供能系统的实际运行性能进行了综合分析.实测结果表明:该三联供系统的发电效率为35％,余热回收效率为52.7％,一次能源综合利用率为82.3％;江水源热泵系统制冷工况在55.6％的负荷率下运行,制热工况在89.3％的负荷率下运行,制冷能效比为3.85,制热能效比为3.97.相对于实际运行策略,系统在设计策略下运行可节能39.9％.
