Air systems treatment guidelines
Problems
The treatment of indoor air not only intended
as a regulation of comfort by controlling tempe-
rature and humidity, but more generally as the
maintenance of an environment intended for the
use of people who is healthy and comfortable,
and constitutes a complex and always relevant
topic. We can describe the air treatment based
on its two main functions:
> “Air conditioning systems may present dange-
• Comfort regulation: obtained by tempera-
ture and humidity control with the help of ma-
chinery using different technologies, such as
direct expansion air conditioners, heat pumps ;
air handling units (UTA) and so on.
• Maintenance of the health of the air: obtai-
ned with the control and relative elimination of
pathogens, such as mold, bacteria, fungi and
viruses, thanks to the use of products that act
directly on air through air dispersion, but also
through cleaning and disinfection of surfaces of
equipment suitable for air treatment.
The Indoor Commission, in 2001, assessed
that many chronic diseases are related to It can
therefore be said that the treatment of air-con-
ditioning agents, intended as an activity aimed
at the prevention and elimination of pathogens
that can spread via air, is a fundamental ele-
ment of a more complex process, known as sa-
nitization: the Italian legislation gives the defini- gi which, thanks to the flow of air, significantly

in Art. 1:
> “are sanitizing activities that concern the com-
plex of procedures and operations aimed at
making certain environments healthy the acti-
vities of cleaning and/or disinfection and/or of
disinfestation or by controlling and improving
the conditions of the microclimate with regard
to temperature, humidity and ventilation or with
regard to the lighting and the noise”
Air quality is the measure of how harmless and
free from pollutants air is. Relative to closed
spaces, i.e. indoor, even the presence of patho-
gens has particular relevance.
aspects of indoor air quality (IAQ), and that the
economic and social damage attributable to in-
door pollution in Italy is likely to be relevant, as
reported on the website of the Ministry of He-

alth. [Link 1 in bibliography] Consequently, the
importance of proper cleaning and sanitization
of environments is evident, without neglecting
aeraulic systems. These are essential for obtai-
ning an optimal microclimate, but cleaning them
plays an essential role as they could constitute
a source of health risk.
We quote the Ministry in this regard:
rous sources of bio-logical or chemical pollution
especially if poorly designed, in poor condi-
tion of cleanliness and maintenance. Colonies
of microorganisms can nestle and multiply in
plants where there is presence of water, mostly
stagnant, such as: humidifiers and air conditio-
ners, vaporizers, heaters, self-frosting refrige-
rators, water systems. “ [Link 2 in bibliography]
Health risks can be classified into three types:
toxic, infectious or allergic risk, men-three pa-
thogens are divided into:
1) microorganisms (fungi, bacteria, viruses, pa-
rasites, protozoa)
2) indoor allergens (dust mites, plant and ani-
mal derived allergens)
3) mold
Areaulic pipelines
Over time the ducts can easily become prey to
microorganisms such as bacteria, mold and fun-
increase the potential contagion among people
present in the same environment.
Indoor pollution - the risks
Pollution by fine dust, dust, pollen, fibres and spo-
res can make life really difficult for those suffering
from allergy (damage to eye mucous membra-
nes, skin, respiratory system), also accelerating
the deterioration of the equipment present inside
the rooms. Bacteria, viruses and fungus, poten-
tially pathogenic, are the cause of contamination
of diseases.
