The application of artificial neural network in HVAC system

Because of the complex calculation for traditional PMV index in HVAC field, the prediction of thermal load is inaccurate, and the PID algorithm can hardly be used to control its system accurately and timely. This article sets forth the theory of artificial neural network (ANN) and its application in this field. Then it introduces the improved BP model used in back-propagation training forward multilevel neural network algorithm, and indicates that the ANN system can be widely used in the HVAC field.
