| 摘 要： | 提出了一类风机盘管节能控制的新方法,将占空比的概念引入风机盘管电动水阀的控制中,在特定的控制周期内充分利用水阀关闭状态下风机盘管的冷却除湿（或供热）能力,利用Mamdani模糊规则与作用模糊子集推理方法,根据室温偏差与偏差变化确定水阀占空比与风机档位。试验结果表明,风机盘管占空比模糊控制方法较传统控制方法的节能量高于30%,同时可达到更好的室温控制效果。

| Abstract: | A new type of energy efficiency control method for fan-coil unit is presented.By introducing the conception of duty ratio into electric valve control,the cooling and dehumidifying capacity of fan-coil unit is fully utilized.By means of Mamdani type fuzzy rule and the Method of Functioning-fuzzy-subset Inference,duty ratio of valve and fan speed signal are identified according to deviation and deviation change of room temperature.It is shown that presented method could achieve at least 30% energy saving than traditional control method as well as a preferable room temperature control effect. |
