结合吸收式热泵的HAT循环系统综合设计与性能分析

DESIGN AND PERFORMANCE ANALYSIS OF HAT CYCLE SYSTEMS WITH ABSORPTION HEAT PUMPS

针对HAT循环在热电联供能力、水回收和烟气排放等方面的问题,采用多种类型的吸收式热泵系统与其结合,对六个综合系统进行模拟,并对结果进行了分析。表明,循环效率方面,采用增温型热泵且放热用于系统内部,其效率要高于向外放热的增热型热泵;水回收方面,开式循环热泵的水回收率高且回收水量灵活,同时排烟温度也高,在110℃以上;热电联供方面,热电输出效果与热泵系统的选择关系密切,对于文中可实现热电联供的三个系统,热电效率分别为0.6285,0.7677,0.6383。

Considering the problems existing in the original HAT cycle such as heat and power gener- ation,water recovery and exhaust temperature,five types of absorption heat pumps are incorporated into HAT cycle.The six types of integration systems are simulated.The results show that,the ef- ficiency and specific work are influenced by the absorption heat pump.The efficiency in the system incorporated with heat transformer is higher than the heat pump;the water recovery ratio and exhaust temperature is high in the system with open cycle absorption heat pump;for the heat and power gen- eration,different heat pumps will have influence on the congeneration,the heat and power efficiency are 0.6285,0.7677 and 0.6383 respectively.
