Summary

The energy-saving effect of a hybrid A/C system during operation phase in springtime was presented quantitatively through field measurements and numerical simulations. A numerical model of the natural ventilation rate for a building with flow control inlets and outlets was proposed in this study by means of a thermal and air flow network analysis. The prediction accuracy of this model was also verified by performing a comparison with field measurements of a hybrid A/C system in an existing office building. Power consumption for A/C was reduced by about 20% on each floor by introducing natural ventilation, and predicted energy savings for the system was about 22.3% on average.
