Types of Mechanical Ventilation

Mechanical ventilation refers to using mechanical means, such as fans and ducts, to move air in and out of a building or room.

There are several different types of mechanical ventilation systems, including:



1. Supply Ventilation

This system brings in fresh air from the outside and distributes it throughout the building or room. This can be done using a centralized system, with air being brought in through a single duct and distributed through a series of vents, or through a decentralized system, where individual units are installed in each room or area.       



2. Exhaust Ventilation

This system removes stale or contaminated air from the building or room and exhausts it to the outside. This can be done using a centralized or decentralized system and is often used in conjunction with supply ventilation to ensure a continuous supply of fresh air.       



3. Balanced Ventilation

This type of system combines both supply and exhaust ventilation to maintain a balance between the amount of air being brought into the building and the amount of air being exhausted. This helps to ensure that indoor air quality is constantly refreshed and prevents the build-up of pollutants.                                                                       


4. Whole-house Mechanical Ventilation

This system is used to change the air in the entire house; it is often used with a central air-conditioning and heating system, which can be either a centralized or decentralized system.


Each type of mechanical ventilation system has its own advantages and disadvantages. The best system for a particular application will depend on factors such as the size and layout of the building, the number of occupants, and the specific ventilation needs of the space.
