Abstract

Effect of three different fresh air modes on the indoor pollutant dispersion is analyzed by the method of CFD (computational fluid dynamics) simulation and experiment. The fresh air modes include natural ventilation, hybrid ventilation and mechanical ventilation with total heat exchanger. Performance of the fresh air modes is compared considering the factors like fresh air volume, heat/cold load and outdoor air parameters etc. In addition, the ventilation performance under different fresh air volume and control modes is contrastively studied under running condition. The result shows that, fresh air volume is the key factor in diluting the pollutant and heat recovery is vital for energy efficiency.
