摘要
以水-溴化锂溶液为工质对,分析了不同发生温度和热源负荷比对三热源互补吸收式热泵循环的性能影响。模拟结果表明,循环在最佳工况下运行高发压力和低发压力均需优化,优化压力随发生温度升高而升高。在相同热源输入条件下,三热源热泵循环产生的制热量能够达到动力余热驱动的1.x效循环和传统低温太阳能驱动的两级循环共同产生的制热量。
Water-lithium bromide was used as the working pair and effects of generation temperature and heat capacity ratio values on performance of triple-heat sources driven absorption heat pump cycle were analyzed. The simulation results show that the high pressure and low pressure values should be optimized to get an optimal performance. The optimized pressure values increase with the increasing of generation tem- perature. The heating capacity produced by coupled cycle can reach that produced by both 1. x effect cycle driven by power waste heat and conventional two-stage cycle driven by low solar thermal energy at the same heat sources conditions.
