Description

110450

The present invention relates to an air cooling beam consisting of a cooling device mounted in the supply air duct and an supply air nozzle unit such as an elongated tear pipe.

For example, the office room today has so many heat generating sources and the outside is also exposed to solar radiation that there is a need to cool the office room to keep the room temperature below 25 degrees. Indoor air classification aims to further define this need. When a room is equipped with a cooling system, it also provides room-specific temperature control.

This is possible with the prior art, but the drawbacks include: the strong convection flow generated by the cold surface, which causes almost all techniques to draw room air through the lamellae, causing the lamellae to become dirty; whereas the ceiling cooling level does not recycle the room but its power is too low ;; ' convectors are cooled with air, which is however returned to the room:. · High speed, resulting in too long a throw - difficult to clean the blade. When light is flowing through the surface of the • radiator. ' · Nail, grease and dust adhering to the damp surface, which are difficult to clean because the battery cannot be removed.

Known technology can be divided into the following five sections: 1. Cooling beams with cold surface or room air circulating through the radiator. This can be further enhanced by adding supply air to the chilled beam.

! .. '2. Blower convectors that circulate large amounts of room air that cools; ·. 25 in the device.

, '' '· 3. A post-cooling radiator in the ventilation duct connected to the duct. . Supply air diffuser.

. · 1. 4. Nozzle convectors placed under the window.

2 110450 5. Cold roof that requires large surfaces and provides little cooling performance.

The object of the invention is to eliminate the above drawbacks and to provide a new type, simple and advantageous so-called. without the chilled beam. The beam according to the invention is characterized in that the cooling device is located on the side of the room and the nozzle unit is attached to the cooling device so that the cooling device remains between the supply air duct and the nozzle unit.

In the supply air cooling beam, the invention only cools and blows the supply air at low speed in the desired direction. The device has no convection surface. In one version, even more than half of the beam surface is thermally insulated to prevent convection flow even at high temperature differences. Despite large temperature differences, the supply air can be blown into the room draft-free with active displacement technology. The cleanability of the lamella radiator is based on the fact that it can be completely removed and removed from the room for maintenance and cleaning.

The invention will now be described by way of example with reference to the accompanying drawings, in which Fig. 1 is a side view of an air cooling beam according to the invention, Fig. 2 is the same as Fig. 1 but viewed from the end of the air cooling beam; Fig. 3 is an axonometric view of the air cooling beam.

Cooling unit. ·; . 2 is disposed on the room space side 4 and the nozzle unit 3 is attached to the cooling device. The cooling device 2 consists of a housing containing a retractable lamella battery 5. The lamella battery 5 is connected to the cooling / heating piping via quick connectors 6. 7. The cooling unit 2 has a flap 8 on the side thereof which can be closed when the cooling unit lamella battery 5 is either in place or removed for cleaning and maintenance. The air cooler bar thus acts as a supply air device, although the • • 30 bellows is not in place.

Fig. 2 shows how the incoming air is discharged into the room 4 by an inlet: # * · · a nozzle unit having an aperture according to Figures 1, 2 and 3 at the top of the mantle.
