Keep cool

The task of the air conditioning technology is to regulate temperature, humidity and air quality in a room to the desired values - independent from the variations of the environmental conditions, of adjoining rooms or atmospheric air.  For this purposes, with the adequate air duct, air conditioners lead away heat (cooling) or lead  it in (heating), increase humidity (humidification) or lower it (dehumidification) and transport the used media (air, water).
