ABSTRACT:
Air outlet tubes for air conditioning systems are subdivided into a plurality of tube portions which are provided with corresponding positive and negative coupling elements at either end. The tube portions are of different form and length so that complete air outlets may be assembled which suit the particular requirements of each working place, desk etc. to be ventilated. With one end the air outlets are plugged into a blow-out hole which is part of the air duct extending underneath the floor. The negative and positive coupling elements may also include plugs and sockets for electric wires and telephone cables which run inside the tube portion. When the outlet tube is assembled from a plurality of tube portions each plug fits into the corresponding socket so that an outlet tube is obtained which does not only conduct the conditioned air but also includes the supply lines for the electric light and the telephone.
