摘　　要：提出了一种太阳能热驱动吸收-喷射热泵系统,介绍了其工作原理,建立了系统各部件的数学模型,分析了驱动热源压力、冷却水出口温度及冷水入口温度对该热泵系统COP和喷射系数的影响。结果表明:该热泵系统不仅可制取较高品位热量,还具有较高的效率;在给定条件下,当驱动热源压力增大和蒸发器冷水入口温度升高时,该系统COP分别由1.52提升至2.02和由1.00提升至4.52。Develops a new absorption-ejector heat pump system driven by solar energy.Presents its operation principle,establishes the mathematical model for each component,and analyses the influences of heat source pressure,cooling water outlet temperature and chilled water inlet temperature on COP and injection coefficient.The results show that this system not only produces higher grade heat,but also has a higher efficiency.Under given conditions,system COP increases from 1.52 to 2.02 with the increase of heat source pressure and from 1.00 to 4.52 with the increase of chilled water temperature of evaporator inlet.
