Abstract

This paper defines the normalization efficiency function, the efficiency similarity of different variable-speed fans, and the efficiency similarity fan station. We propose a efficiency optimization method for such fan stations. Based on the efficiency function characteristics which can be approximately considered a concave, non-negative function through the origin, it gives optimal control and optimal switch method and gives the minimum total power consumption. This method is independent of the linearity or nonlinearity of the system and has no need for the system’s state equation or transfer function. In the constant output pressure fan station, the optimal control method is to keep the same flow rate for each fan, and the optimal switch points are at the same efficiency points of different operating methods. Since the shapes of efficiency functions in nature are similar, the method given by this paper can be used in other fields.
