Fuzzy control method for variable static pressure based on regulation rules of terminal damper position in VAV air conditioning systems
摘要：
分析了送风量调节中末端阀位与送风静压设定值之间的调控关系。基于作用模糊子集推理方法，提出了基于末端阀位调控规则的变静压模糊控制方法，该方法易于模块化封装，调试简单，便于实际工程应用。通过对比试验研究，验证了该方法的控制性能及节能效果。结果表明：与传统的定静压法相比，采用变静压模糊控制方法在冬季和夏季工况下可分别减少14%和16%的送风机电耗；通过合理选择静压变化量的模糊基本论域，采用变静压模糊控制方法在冬季和夏季工况下分别可进一步减少33%和11%的送风机电耗。
Abstract：
Analyses the regulation relationship between terminal damper position and the static pressure set-point in the regulating process of supply air rate. Proposes a fuzzy control method for variable static pressure based on regulation rules of terminal damper position using functioning fuzzy subset inference method, which is benefit for modularized encapsulation, easy commissioning and practical engineering application. Validates the control performance and energy saving effect of the method by comparative experiment study. The results show that the variable static pressure fuzzy control method can reduce the power consumption of fans by 14% and 16% in winter and summer conditions, respectively, compared with the conventional constant static pressure method. By reasonably selecting the fuzzy basic domain of static pressure variation, the control method can further reduce the power consumption of fans by 33% and 11% in winter and summer conditions, respectively.
