Description

Apparatus for controlling supply amount of air and method

The present invention relates to an air volume control device and a method thereof, and more particularly, to an air volume control device and a method for controlling the air volume supplied in a ventilation hole for ventilating indoor air of a building or an air conditioner for heating and cooling.

Ventilation facilities are installed in large buildings such as apartments, buildings, and libraries. In particular, according to the recently announced building equipment standard, the installation of such ventilation equipment is mandatory when new apartments with more than 100 households are constructed.

In general, the ventilation system has a structure such as a duct whose ends are connected to the inside and outside of the building, respectively. The duct is divided into an air supply duct for introducing outside air and an exhaust duct for discharging the air inside, respectively, to flow air inside and outside the building.

1 is a perspective view of a configuration of a ventilation system according to the prior art. According to this, the ducts 13, 14 and 15 are installed in the installation space corresponding to the slab and the ceiling of the building. As shown, a plurality of ducts 13, 14, and 15 are installed along a predetermined path.

The ducts 13, 14, and 15 are composed of first and second ducts 13 and 14, and the first and second ducts 13 and 14 are in addition to the air supply duct 13 and the exhaust duct 14. ). The air supply duct 13 serves to supply the outside air to the room, and the exhaust duct 14 serves to discharge the air of the room to the outside.

In this case, a plurality of ducts (13, 14, 15) may be installed for the ventilation of each room of a separate space, for example, a multi-unit house. That is, as shown in FIG. 1, the second duct 15 may be installed separately from the first ducts 13 and 14.

(15) will inevitably intersect. In addition, the intersection between the ducts 13, 14, and 15 occurs more frequently as the number of the ventilation spaces increases.

However, as shown in the drawing, the second duct 15 may include the first duct 13 to prevent interference between the two ducts 13, 14, and 15 during the intersection of the first and second ducts 13, 14, and 15. Since it is to be installed to protrude relative to (14), the height of the space for installing the ventilation equipment is increased. This results in a problem that the overall height of the building increases or the space used for the building decreases.
