Description

This paper describes a newly developed total energy consumption model of a fan subsystem, which consists of fan, driveline, motor, and variable-speed drive. How to use this model for automated continuous commissioning is explained and verified using an experimental study. This model can accurately simulate the total energy consumption of a fan subsystem, which can be easily measured. Therefore, this model is useful for the automated continuous commissioning of a fan subsystem during operation. The simulation results were verified using measured data in a real variable-air-volume system. The average difference between the simulated and measured data is 5.1%, which is accurate enough from an automated continuous commissioning point of view to monitor the operation of a fan subsystem and detect faults during operation. An experiment demonstrated that loose fan belts can be detected and the results are discussed as an example showing that the model can successfully detect this fault.
