空气源热泵热水机组最佳运行时段模糊判定的研究

Research on the optimal running time of air-source heat pump water heater based on fuzzy determination

根据空气源热泵热水机组制热性能随环境温度升高而升高的规律,以热泵机组前一日开机时间和环境温度变化量作为输入量,设计机组当日开机时间的模糊判定控制系统,运用MATLAB软件验证模糊控制系统的效果。结果表明,该模糊判定控制系统可根据前一日开机时间和温度变量的变化情况,实时决定最佳运行时段,对提高热泵系统的节能性能具有重要意义。

In consideration of the problem that the heating performance of air-source heat pump water heater system increases with the increase of environment temperature, designs a fuzzy determination control system of start-up time using the start-up time of yesterday and environment temperature variety as input parameters, and tests the effect of this system by MATLAB. The result shows that this fuzzy determination control system can determine the optimal running time in real time according to the start-up time of yesterday and environment temperature variety, which is benefit to the energy-saving of heat pump water heater system.
