Company Air Handling Unit Online Management System /
Currently company air handling units are used for ventilation of buildings and they can only be controlled in local area network (LAN). This does not allow the company customers to control the microclimate of their home in a convenient way (e.g. when they are away from home). Therefore, there is a …

Improving the indoor air quality (IAQ) through application of the air cleaning technologies for offices building simulated in environmental chamber
Indoor air quality (IAQ) is very important issue in residential and commercial buildings, because human spend almost 90% of their life indoor. IAQ problems effect on the health of the occupants, and lead to reduction of the efficiency and output in workplaces. The main objective of this study is to …
