Experimental Study of Hybrid Ventilation on the Cooling Effect of Buildings

Project Details


With growing concern for the climate changes and increasing energy costs, natural ventilation, ratherthan the mechanical ventilation, became a desirable choice to cool and ventilate buildings. However, naturalventilation is dependent on the external wind speed, direction and temperature difference between indoor andoutdoor. Hybrid ventilation, takes advantage of both natural and mechanical ventilation, provides anenergy-efficient solution that ventilates while maintaining comfortable indoor temperature and air quality.This study plans to use wind tunnel experiments and Computational Fluid Dynamics (CFD) model toinvestigate hybrid ventilation for large partitioned buildings. The effects of opening area, location, externalwind speed and direction on the hybrid ventilation will be systemically investigated. Besides, theapplicability and energy efficiency of hybrid ventilation in Taiwan will be analyzed. The results of this studycould be used to evaluate the feasibility and cooling effect of hybrid ventilation for large partitionedbuildings in Taiwan.
