摘要
使以天然气为能源的楼宇式小型热电冷三联供系统(BCHP,Building Cooling Heating & Power)中的烟气型双效吸收式制冷机在冬季作热泵运行,利用回收烟气冷凝热的运行方式进行了建模与模拟研究,证明了在该方式下运行是可行的,指出影响热泵温升提高的主要因素是高压发生器的溶液浓度、温度和压力,根据这些影响因素可以分析热泵机组的升温特性,用于指导机组实际运行时的参数调节。
A double-effect exhaust-driven absorption chiller is in common use as a cooling device in many natural gas fueled building cooling heating and power （BCHP） systems. In former studies, we had put forward that the absorption chiller could also operate as a heat pump to recover the latent heat of vapor in the flue gas to provide heating in winter. A simulation model has been developed predicting the performance of the absorption heat pump. The results indicated that the absorption machine can be operated in the heat recovery/heating mode reliably. And it was found that the main factors influencing the increase of temperature lift are the solution concentration, temperature and pressure in the high-temperature generator. These factors can be used to determine the range of temperature lift of the heat pump.
