There are five major types of ventilation systems - Natural, mechanical, spot, hybrid, and task ambient conditioning (TAC).
Every time you open the window in your home and let fresh air enter, you are applying natural ventilation.
This setup brings fresh air into the building without any mechanical force, instead using buoyancy and wind forces.
Given that the air outside is not always fresher than the one inside, this system is being replaced by mechanical ventilation and other options.
Mechanical ventilation is when fans are installed on walls or windows to supply fresh air and get rid of stale air. Sometimes, mechanical ventilation and natural ventilation are not enough individually.
For instance, some times of the day may not be suitable for natural ventilation. It is possible to have a setup whereby you can alternate between natural and me
Spot ventilation is an improvement to mechanical and natural ventilation. Exhaust fans are placed in different rooms to freshen the air and even remove moisture from the rooms.
Then there is task ambient conditioning, which restricts the adjustments of thermal conditions to individual environments. Air is supplied to occupants in a controlled manner.
