Abstract:

Aiming at various faults in an air conditioning system, the fault characteristics are analyzed.The influence of the faults on the energy consumption and thermal comfort of the system are also discussed.The simulation results show that the measurement faults of the supply air temperature can lead to the increase in energy consumption.According to the fault characteristics, a data-driven method based on a neural network is presented to detect and diagnose the faults of air handling units.First, the historical data are selected to train the neural network so that it can recognize and predict the operation of the system.Then, the faults can be diagnosed by calculating the relative errors denoting the difference between the measuring values and the prediction outputs.Finally, the fault diagnosis strategy using the neural network is validated by using a simulator based on the TRNSYS platform.The results show that the neural network can diagnose different faults of the temperature, the flow rate and the pressure sensors in the air conditioning system.
