What Is Ventilation and its Use?
Ventilation is actually a process through which
fresh air is intentionally pushed inside a space and stale air is
thrown out. The ventilating process can be achieved naturally or
mechanically. The ventilators and Ac have been used since a long
time to maintain a nice air flow inside a building or a house. Fresh
air helps to lower down the temperature of the house. Ventilation is
very essential part of home improvement.
Artificial infiltration: apart from intentional ventilation, air
also enters the building through infiltration process. Infiltration
process is uncontrollable air flow in a certain space by
unintentional and adventitious cracks and gaps in the envelope of
the building. The loss of air through enclosed space is known as
exfiltration. The amount of air that will enter inside the building
depends upon the porosity and the magnitude of various natural
factors like temperature and wind. Various vents and openings in the
building created deliberately are also a part of the ventilating
design. They form routes for the natural airflow at times when
pressure acting at such places is subjugated by the climatic
conditions. Natural air flow or infiltration is quite different from
mechanical infiltration. Air infiltration helps in adding to the
amount of air entering inside the building and but may hamper or
alter the intentional air flow pattern.
The magnitude of the filtration process is often ignored by the
architect or the designer which decreases the performance, extreme
energy performance and inadequate heating (or cooling) of the
building. There are some air tightness standards that are often used
by the countries to limit the infiltration loss.
Maintaining proper standards during deigning any building or house
is compulsory so that various home improvement factors are included.
Air recirculation is used commercially to help in thermal
conditioning. The air that is circulated across the building is
filtered from time to time to settle down dust particles from it.
But it usually does not provide any helpful conditioning since
oxygen and dust particles are not removed or replenished properly
and oxygen is not recovered. Some of the leakages through ducts and
ventilation joints, air conditioning or heating are substantial.
According to Modera in 1993, estimates that more than 20% of the
heat through North American warm air systems may be lost by duct
leakage. Also most of the opening in the building accounts for the
entry of pollutants and dust particles. The design used to construct
a particular building really matters a lot in deciding whether the
ventilating areas and openings in the building are really helping in
conditioning or are just adding to improper ventilation. So,
designing a building in a right form and design is very important to
let people stay in it peacefully and happily.
