- In the present study performance of an airflow window in removing contaminants as well as providing thermal comfort for the occupants was investigated. Both natural/mixed ventilation methods were studied and the full heating load as well as contaminant sources in the office rooms considered. Then, the local and average temperature, relative humidity, velocity as well as CO2 and dust concentration were extracted from simulation results and compared to criteria in international ventilation standards. It was found that except in the big room having 8 m×6 m flooring, natural ventilation from the airflow window can satisfy the thermal and relative humidity conditions in the international ventilation standard except for the American Society of Heating, Refrigerating and Air-Conditioning Engineers. However, the thermal comfort in the room which was measured by extended predicted mean vote could not be achieved when the window operates in the natural ventilation mode, even with a 0.4 m height opening in the small (3 m×4 m) room. Finally, results indicated that the airflow ventilation system installed in small and medium offices operation can provide indoor condition in the ventilation standard either in natural/mixed operation mode consuming less energy than the traditional heating, ventilation, and air conditioning. Besides, the airflow system not only was not able to provide thermal comfort condition in the big office but also its application was not economically feasible.
