Study on the Indoor Air Quality in Hotel

This paper studies the ventilation in guest room in hotel. To air-conditioning system with fan and fresh air, the pollutants indoor are mainly removed by fresh air. Enlarging the fresh air volume can develop the indoor air quality, but goes against to the energy saving. This paper simulates the CO₂ concentration indoor under different fresh air volume when the bathroom door opens and closed. The result indicates that only enlarging the fresh air volume affects the IAQ slightly, and exhaust fan can satisfy the ventilation indoor whether the bedroom door opens or closed.
