An Energy-saving Model-based Air Balancing Method for the Ventilation System

In this paper, an energy-saving oriented model-based air balancing method aiming at reducing the energy consumption and achieving the air balancing among all air terminals is presented. The method includes two layers: one is the static pressure control layer, and the other is the air balancing layer. The first layer is to modulate the speed of the fan with the variance of total airflow rates to achieve the aim of energy saving. The second layer is to implement the air balancing among the terminals. Experimental tests are carried out in the experimental rig with five terminals to validate the performance of the proposed method.
