Air conditioning is the technique of modifying, controlling and regulating the climate (temperature, humidity, dust levels, etc..) A place for comfort reasons (offices, houses) or for technical reasons (laboratory medical, local manufacturing of electronic components, operating theaters, computer rooms).
The main features are modified, controlled or regulated are:
the degree of pollution of ambient air (room to be treated): renewal, either by forced extraction of air from the room, either by forced introduction of fresh air (outside air) in the room or by partial replacement of ambient air pollution (addition of a mixing box).
the air temperature: modification by season (heating or cooling),
the humidity of the air treated: humidification or dehumidification
the dust content of the air filtration treatment of the air blown or taken,
maintaining constant indoor conditions (control).
While heat and humidity rise within elementary techniques, chill and dehumidify the air require sophisticated techniques. In practice, we mainly discuss conditioning in these last two objectives.
The air conditioning is essentially the technique of heat pumps and is increasingly associated in one device, a "reversible air conditioner" (summer cooling, winter heating).
