Numerical Evaluation of Ventilation Efficiency of Window Type Ventilation Systems

International Journal of Air-Conditioning and Refrigeration, 2019
Ventilation in buildings is the simplest and most convenient way to purify indoor air. However, when the ventilation is not enough due to natural ventilation, it should be cleaned by mechanical ventilation or air purifier. This process requires building energy.
