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。
A heat pump system based on solar thermal drive was introduced. Its working principle was introduced. The mathematical model of each component of the system was established. The effects of driving heat source pressure, cooling water outlet temperature and cold water inlet temperature on the COP and injection coefficient Impact. The results show that the heat pump system not only can produce higher grade heat but also has higher efficiency. Under certain conditions, when the driving heat source pressure increases and the evaporator cold water inlet temperature increases, the COP of the system increases by 1.52 To 2.02 and from 1.00 to 4.52.
