The primary functions of ventilation systems include the delivery of outdoor
air to the occupants, the removal of indoor contaminants and the maintenance of
thermal comfort conditions in the occupied zones. The objective of this project is to
study a backup ventilation system for individual lecturers’ office space mainly during
power failure and when ventilation is not available such as during night. During
blackout, the period to repair the power failure takes at least one day. Therefore, the
backup ventilation design is important to make sure the lecturers feel comfortable
when they are working in their office.
The project undertaken looked at the amount of air requirement to the office
space in level 3 of Block 17. First, the flow rate of the main blower is determined.
Then, the total flow rate at each VAV is compared with the main blower. The total
flow rate at each VAV is much lower than the flow rate of the blower. It means that
there is a lot of energy wasted during the ventilation process. After comparing these
flow rates, the minimum requirement of the ventilation rate is individual lecturer’s
office rooms are calculated. The minimum requirement for the ventilation is much
lesser than the flow rate supplied by the main blower to each room. Therefore, it will
be a lot of energy wasted if we do the backup power supply for the main blower.
Based on the results obtained from theoretical and experimental works in this project,
the backup ventilation system is feasible to install
