| 摘 要： | 通过对热泵系统整体质量平衡、热平衡和内部部件之间的传热分析,建立了增热型吸收式热泵数学模型,并用该模型分析了某电厂热泵机组在运行中循环水温度、热网供水温度和汽轮机抽汽压力对机组制热系数的影响,通过模拟得出在不同工况下维持热泵机组制热系数在1.66以上所对应的汽轮机抽汽压力的变化范围。

| Abstract: | A simulation model of absorption heat pump had been developed by analyzing mass and heat balances and heat transfer relationships of the overall system and its components. The model was used for analyzing the influence of temperature of circulating water and heating network water and turbine extraction pressure on system COP during a power plant heat pump unit operation. Obtain the variation range of turbine extraction pressure in different working conditions in order to keeping the system COP above 1. 66 by simulation. |
