Tools for Evaluating Fault Detection and Diagnostic Methods for Dual Duct Double Fan Systems



Shokouh Pourarian, Jin Wen, Xiwang Li, Daniel Veronica, Xiaohui Zhou, Ran Liu


Dynamic system simulation tools are needed for developing advanced control, operation, and fault detection and diagnosis techniques for heating, ventilation, and air conditioning (HVAC) systems. There has been a lack of dynamic simulation tool development focusing on dual duct systems. The work here summarizes an effort to develop and validate a dynamic simulation model that is able to simulate fault free and faulty operational data for the air flow network in a dual duct double fan system. The challenges and solutions of simulating such dual duct dual fan air flow network are discussed. Experimental data generated from a small commercial building in a laboratory facility are used to validate the developed model. A systematic validation procedure is developed to validate the model which shows good agreements between simulated outputs and experimental data.
