Recurring to the good nonlinear mapped performance of neural network and the experimental data of a direct evaporative cooling air conditioner with GLASdek pad, establishes a three layer back propagation neural network to predict the air handling performance of the conditioner under various working conditions. The predicting result proves consistent with the experimental data.
