The room is supplied with centrally purified outside air (primary air). The used outside air flows through the nozzle into the mixing chamber. At the same time secondary air that flows through the grille and the convector into the mixing chamber is induced. The air flows are mixed and flow as supply air through the special diffuser slots horizontally into the room. Eight different lengths and three different nozzle sizes (1 – 3) are available. The heat exchanger is available as a 2-conducter-system for cooling as well as heating during “change-over-operation”. Cooling or heating each room independently of other rooms at any time is possible with the 4-conducter system.
FUNCTION AND EFFECT
The two-sided ceiling induction diffuser DIA-300 enables comfortable air conditioning of rooms with high cooling loads. The energy advantages of water as a transport medium combined with optimized air and ceiling flow characteristics are used to full extent. The shallow case height of the series DIA-300 is equally suitable for low ceilings in new constructions and renovation of existing buildings with an ideal room height range of 2,6 m to 4,0 m.
