Definitions

This invention relates to a supply air nozzle which is intended to be installed in the sleeve of a supply air duct and through which supply air is discharged into a room, and which supply air nozzle has several chambers.
Offices, classrooms, negotiation and meeting rooms often contain a large number of people relatively densely packed into the same space. This large number of people in the same space necessitates, in terms of temperature and comfort, that the amount of ventilation supply air (qv) must be increased to such an extent that the temperature and comfort at least remain at the level required by the building regulations.
the supply air amount regulations are not met if the air flow speed in an occupied area exceeds 0.2 m/s.
the occupied area of a room is usually defined as an area extending from a height of 0.1 m above the floor to a height of 1.8 m above the floor, i.e as the area occupied by the people.
a large amount of supply air into a space which is small in proportion to the number of people often causes high flow speeds in the occupied area which is sensed as an uncomfortable draft by the occupants.
the most common air distribution solutions are: a low-velocity unit, ceiling or wall diffuser, chilled beam or a supply air duct.
the low-velocity units which are installed at the floor level, require, in addition to the physical floor space, a lot of floor space, a so-called protective distance, for the air flows discharged by the diffusers.
the throw lengths of the ceiling and wall diffusers usually exceed the dimensions of the space, i.e. the air flow continues along the wall, down to the floor.
the chilled beams are primarily used for cooling offices and similar premises. Their air flow is not sufficient to meet the minimum air amount requirement of these premises.
the supply air duct is intended to evenly distribute the supply air evenly within the space.
the discharge sleeve of the supply air duct can be perforated, the sleeve of the supply air duct can have projecting jets or the supply air duct can be provided with supply air nozzles.
the above-mentioned supply air duct solutions share in common an excessive throw length as well as a poor supply air/indoor air mixing ratio.
the excessive throw length results in more or less the same problems as the above-described ceiling and wall diffusers.
the temperature of the supply air (qv) being lower than the temperature of the indoor air, the poor supply air (qv)/indoor air mixing ratio usually causes the supply air flow to make, after the discharge outlet, a tight turn towards the occupied area.
the supply air duct according to the invention has several supply air nozzles serving to eliminate the above-mentioned disadvantages.
the supply air duct according to the invention is characterized in that the supply air nozzle is divided into chambers by one or more partition walls wind upwards round a central shaft.
the actual invention lies in the structure of the supply air nozzle wherein the interior is, in an especially preferred embodiment, divided into two, three or more sections or chambers separated from each other by partition walls forming an angle which is equally divided depending on the number of the partition walls. In practice, it has been found to be preferable to divide the supply air nozzle into three sections or chambers but the number of the chambers can also be higher or lower.
the partition walls of the supply air nozzle are in the shape of an upward spiral, with each partition wall winding, in the direction of the air flow, round the central shaft over an angle of approximately 120°.
the pitch angle and length of the upward partition wall spiral can be lower or higher.
the partition wall pitch angle can also be adjustable for an optimal result.
the upward-spiraling partition walls make the air flows passing through the supply air nozzle rotate intensively, resulting in that the supply air (qv), under the influence of the centrifugal force, effectively is blended into the indoor air, immediately after the discharge outlet of the supply air nozzle.
the negligible temperature difference between the supply and indoor air ensures that the supply air (qv) under no conditions turns downwards, in the direction of the occupied area.
the throw length of the supply air becomes considerably smaller.
