Here, the supply air is fed in at a rate to ensure that the concentration of impurities is equal in all parts of the premises. Likewise, the temperature differences are negligible in the building, which benefits comfort. This is the most common flow principle in our premises on account of the comfort benefits. Supply air is generally diffused at ceiling level or from walls close to the ceiling at a relatively high impulse rate. In order to prevent draughts, supply air diffusers must be chosen with care to ensure that the throw, spread, etc. are well balanced for the size of the room.
A great choice for interiors…
• …such as classrooms, restaurants and offices
• …with low to medium-high ceilings
• …where supply air can be diffused at ceiling level
• …with strict comfort requirements, draught-free throughout the occupied zone
• …with a need to balance great differences in temperature between supply air and the ambient temperature (= high cooling effect)
