BUSWELL, R.A., HAVES, P. and SALSBURY, T.I., 1997. A model-based approach to the commissioning of HVAC systems. IN: Proceedings of CLIMA, Prague, The Czech Republic, 18pp.
The paper describes how first principles models can be used to assist in the commissioning
of HVAC systems. The techniques utilise models that are extended to treat different
types of faults. A sequence of test signals is applied to the system under test and the
measured sensor and control signals are used to estimate parameters of the models relating
to certain faults. These parameter estimates are compared with values calculated from
design information. Differences are taken to be evidence of faulty or unsuitable equipment,
incorrect installation, or inadequate commissioning. Results are presented from tests
carried out on an air handling unit test rig at Loughborough University. The work has
been performed as part of a UK collaborative research project on the practical application
of fault detection and diagnosis to HVAC systems and as part of IEA Annex 34.
