Introduction
Ventilation
is generally defined as the replacement of stale air by fresh or outside air. Satisfactory
ventilation means comfortable atmosphere, although an exchange of fresh for
stale air is not necessarily required.
By fresh air is meant air that is
relatively free from such impurities as dust, microbes, toxic gases and
objectionable odours.
Ventilation
The
term ventilation is used to mean the free passage of clean air in a structure.
In other words, the removal of all vitiated air from a building and its
replacement with fresh air is known as ventilation.
Factors
affecting ventilation
The following factors affect the
ventilation.
1. Air changes
2. Humidity
3. Quality of air
4. Temperature
5. Use of building
