| 摘 要： | 针对溴化锂吸收式热泵系统,研究了在热力循环过程中影响其性能的相关参数,这些参数包括驱动热源压力、冷却水进出口温度以及冷媒水温度。运用控制变量法,从理论上模拟计算了不同运行参数下溴化锂吸收式热泵系统的COP。研究表明,当上述4个运行参数发生改变时,系统COP也随之发生变化。计算结果显示,随着驱动热源压力和冷媒水温度的升高,系统COP也随之升高;当冷却水进出口温度升高时,系统COP反而下降。

| Abstract: | For the system of Lithium Bromide Absorption Heat Pump(LBAHP), parameters that affect the performance of LBAHP are researched in the process of thermodynamic cycle, including the pressure of driving heat source, the temperatures of inlet and outlet cooling water, and refrigerant water temperature. The overall COP of the system under different operating conditions is calculated by control variable. Accordingly, COP would be changed when the above four parameters is converted, the calculation results indicated that COP is increased with the rising of the pressure of driving heat source and refrigerant water temperature, while COP decreased as the temperatures of inlet and outlet cooling water went up. |
