An air conditioner (AC) produces and maintains preselected ambient conditions within defined areas. Temperature, humidity and air quality in particular are controlled. Air conditioners provide a comfortable environment for both people and animals. The required ambient conditions for systems and machines are established in machine rooms.
Distributed and centrally controlled air conditioning systems
A fundamental differentiation is made between distributed and centrally controlled air conditioning systems. Distributed air conditioners are used for climatic control of individual rooms, whereas central air conditioning systems are used for the heating and cooling of entire buildings.
On central air conditioning systems, the technical functions such as the movement of air, filtering, temperature control, humidifying and drying are centrally implemented in an air supply and return unit. Central air conditioning systems enable energy efficient air treatment and are independent of both the site and facades. Central implementation means larger construction designs, which enable universal application of components with low losses such as fans and recuperators.
Blower drives, compressor drives or pump drives require switching and protection devices (DIL+ PKZ/NZM) as well as control circuit devices (RMQ). Should they be speed controlled, frequency inverters (H-Max) are also used.
On fixed speed drives, an improved starting performance can be achieved using the soft starters DS/DM instead of a DOL-start or star/delta start.
Control of an air conditioning system can be implemented with easy Control/XC or combined with distributed operation via the Operator Panels easy HMI to XV.
