Résumé

A dynamic mathematical model for a DX A/C system has been developed. The dynamic model, written in state-space representation which was suitable for designing multivariable control, was linearized at steady-state operating points. The linearized model has been validated by comparing the model simulation results with the experimental data obtained from an experimental DX A/C system. The simulated results agreed well with the experimental data, suggesting that the model developed was able to capture the transient characteristics of the DX A/C system modelled. It is expected that the model developed can be useful in designing a multi-input multi-output controller to simultaneously control indoor air temperature and humidity in a space served by a DX A/C system.
