Air treatment and air conditioning - General

Maintaining the ambient conditions of a room serves several purposes:

• satisfy occupancy comfort requirements ;

• meet the requirements of a manufacturing process or laboratory;

• ensure the preservation of buildings, as damp and cold quickly damage walls and roofs.

Air treatment is not limited to maintaining room temperature. Many other factors can be taken into account, such as hygrometry, air quality, noise level, precision and stability of parameters, aesthetics, air diffusion...

It calls on a wide range of technologies, requiring knowledge of specialties as diverse as heat engineering, hydraulics, aeraulics, acoustics, filtration, chemistry, IT, automation, regulation and metrology.

The primary era of simple heating is over. Human beings aspire to thermal, acoustic, lighting and air quality comfort. Air conditioning through air handling meets these new requirements.

Before developing the various aspects of air treatment, we'll review the different notions of comfort and air pollution and their effects on human beings, as well as the components encountered in air treatment.

This is not a catalog of typical solutions, but rather a presentation of the basic selection and calculation principles to help the reader design air-handling systems from the simplest to the most complex.
