本文从现代建筑的楼宇自控系统与节能的定量化控制的关系方面讨论怎样对楼宇自控对象进行节能定量化控制,具体讨论了“变风量空调系统较高精度的节能控制”和“给排水系统中的电机群组的模型化控制节能”问题。 This article discusses how to quantify the energy-saving of building self-control objects in terms of the relationship between the building automation system and the quantitative control of energy-saving in modern architecture, and discusses in detail the “high-precision energy-saving control of variable air volume air-conditioning system” and “ Model control of a motor group in a drainage system saves energy ”problem.
