| 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. |
