Climate control in the building by using the air conditioning system (ACS), which allows you to keep within certain limits, all or only specific parameters of the air of a closed- premises of the buildings (relative humidity, temperature, circulation rate and purity). Climate control with sle, can provide as requested change is in the room air, and automatically maintain the set values in this air, regardless of the external climate and internal mode indoors.

Moreover, climate control with by systems of technological conditioning rooms in which people reside permanently must comply with hygiene standards. How to comfort cooling systems, and systems Technology conditioning may be a once-through and recirculation. Climate control with recirculation of air conditioning systems are used where within a day or a year dominated by periodic and excessive heat buildings.
