What are the Different Kinds of Ventilation?
Ventilation is intentional or unintentional flow
of air in a certain space or area to add to the quantity of fresh
air and pull out the stale air out. Ventilation is essential part of
home improvement. A mistake made by not creating proper ventilation
places inside any house or building can be very dangerous. Since
centuries architects have been taking care of ventilation areas and
vents inside various designs of houses. Proper ventilation not just
allows air to exchange inside the building but it also assists in
maintaining the temperature of the place according to the existing
climatic conditions. There are many types of ventilation:
Mechanical ventilation: it is quiet opposite to natural ventilation
and takes place through a direct injection or a handling unit to any
space using a fan. The exhaust fans can increase the natural
ventilation or infiltration process and therefore enhances the rate
of the air flow inside the building. Use of artificial or mechanical
source is carried out in case of mechanical ventilation. Most of the
times use of exhaust fan is made to push out the stale air and bring
in oodles of fresh air to maintain the temperature of the building.
Infiltration: It is a process that is different from ventilation and
is mostly used to collect ventilation air inside any room or
building.
Natural ventilation: it usually involves connect the naturally
available sources that remove or supply air within an enclosed
space. Natural ventilation is further divided in to two processes
like stack ventilation and wind driven ventilation. Both these types
of ventilation are different from each other. Stack ventilation
depends upon the buoyancy of the heated up air. The more is the
amount of heated air the better is the stack ventilation. Wind
driven ventilation, on the other hand depends on the force of the
existing wind to push and pull the air from an enclosed place. Wind
driven ventilation can be easily understood through its name. It is
derived through a force, push or thrust of air within a particular
space.
DVC or demand controlled ventilation helps in a better ventilation
in home improvement designs. It helps in incorporating fresh air and
saving the energy. Demand controlled ventilation is used to reduce
the sum total of outdoor supply of air. The demand controlled
ventilation is fitted with CO2 censors that help in managing the
ventilation according to the number of occupants. In design
occupancy, the demand controlled ventilation provides the same
quantity of outdoor air as done by the ventilation rate method.
Although demand controlled ventilation is able to generate
considerable amount of energy savings at times when occupied space
is below the level of design.
All these types of ventilation are considered while designing a
building or house to allow right amount of air inside it.
