Description

Structure of duct for air ventilation

The present invention relates to an air intake duct for inhaling and exhausting outside air in an enclosed space such as an apartment or a villa officetel. More specifically, the present invention relates to a ventilation unit (motor, blower) in a space such as an assembly facility. The outside air sucked by the filter, silencer, heat exchanger and humidifier, etc. can be supplied to each space (room) with the air volume uniformly or strongly and weakly supplied and blown from the ventilation unit. By uniformly distributing the air flow per unit area through the duct having the air splitting inductor, the flow velocity of each unit area is uniform even when passing through curved surfaces such as "T", "A", and elbow pipes. So that the noise can be reduced and the amount of blown air blown from the ventilation unit can be evenly distributed and discharged in the designed amount. One relates to the structure of an air intake duct.

In general, a ventilation facility that draws outside fresh air into the room and distributes contaminated air to the outside is mandatory to be installed in the construction of a high-rise building, and the air reprocessed from the ventilation unit is In order to discharge the polluted air in the workplace, the ventilation duct is installed in the workplaces where the production assembly line is arranged, and the duct is connected to the ventilation unit to supply air to each workplace. To ensure supply cycles.

In the case of the above-mentioned high-rise building, the height of the dog dog between the boson and the diaphragm is designed to be high in consideration of the installation of fire-fighting equipment, lighting equipment, electrical equipment, telephone equipment, and intake and exhaust duct equipment. The large plant space allows the arrangement of individual plants according to kinematic and mechanical design dimensions.

Also. In the latter workplace, the height of the doug falcon can be adequately taken into account according to the mechanical equipment of the workplace compared to the former, so it is not restricted to the height of the doug falcon, and the firefighting equipment, lighting equipment, electric equipment, telephone equipment and Intake and exhaust duct equipment can be installed.

The intake and exhaust ducts of the above facilities occupy a large space because they have to be connected to each room. Intake and exhaust ducts are connected from the ventilation units installed in the building so that the amount of discharge from the ventilation units can be controlled and distributed according to the space area of each room.

Since the installation space of the intake and exhaust duct is not restricted as described above, the intake and exhaust duct can be arranged only by designing the rated voltage and the flow rate of the ventilation unit in consideration of the desired flow rate of the air in each room. Therefore, the shape or size of the intake and exhaust duct can be freely selected and installed.

However, when the height of the douger is low or the constrained dimension, the air flowed from the ventilation unit to the intake and exhaust duct changes as the unit area of the intake and exhaust duct passes through the curved surface. Due to the difference, the noise is generated and the amount of air discharged is not fixed.

The present invention is to solve the above problems, to maintain a constant flow of the air discharged from the ventilation unit in forming the intake and exhaust duct to be applied to the height of the douger or restricted dimensions and also to minimize the change in the flow rate By forming a plurality of air splitting inductors on the inner surface of the intake and exhaust ducts to secure a split flow path partitioned by each air splitting insulator, the flow rate per unit area of air is increased and decreased, and the flow rate is distributed and distributed to maintain a constant flow rate By doing so, it is possible to reduce the noise caused by the difference in the flow rate as in the prior art, and to provide a structure of the air intake and exhaust duct that can distribute the fresh air in accordance with the design value in the desired room of a certain amount of air.

The present invention provides an intake and exhaust duct which is applied to a low or restricted dimension of a dog dog between a building and a half of a building, comprising: an intake and exhaust duct having a rectangular channel of a horizontal dimension wider than a vertical dimension; The basic feature is that a plurality of air splitting inductors having the same straight line or radius of curvature as the flow path are formed in the intake and exhaust duct.

The flow path of the present invention is provided with a plurality of narrow flow passages divided by the air dividing induction partition, so that the flow rate per unit area can be maintained uniformly to reduce noise, and also the amount of air blown from the ventilation unit It will be evenly distributed in this designed amount.

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

The intake and exhaust duct 100, which is applied to the height or the restricted height of the dog dog between the building and the half of the building is arranged in the dog dog 10 of the building as shown in Figure 1, is connected to the ventilation unit 20 Will be distributed.

As described above, an electric motor, a blower fan, a filter, a silencer, a heat exchanger, and a humidifier are installed in the ventilation unit 20 to distribute external air to the intake and exhaust duct 100.

The intake and exhaust ducts 100 connected to the ventilation unit 20 are straight pipe 110, "T" shaped pipe 120, "a" shaped pipe 130 and elbow pipe as shown in Figures 2 to 4a, b The 140 are connected and assembled to form a duct line, and the duct line supplies and distributes the fresh air from outside through a spout (not shown) to each room.

In particular, the intake and exhaust duct 100 of the present invention is composed of a rectangular flow passage 101 of the horizontal dimension wider than the vertical dimension so that the height of the dog dog between the floor and the half of the building as shown in the figure is low. .

The intake and exhaust duct 100, because the horizontal dimension is larger than the vertical dimension, in the case of the straight pipe 110 can be evenly distributed through the air, curved "T" shaped pipe 120, "A" shaped pipe ( 130) and the elbow tube 140, the inside of the curvature radius is small and the outside is wide due to the deviation of the curvature radius, the flow velocity of air is different from the inside and outside of the radius of curvature, the air split induction gap (102) In the absence of), air can cause vortexing to generate noise and cause a problem of inconsistent airflow.

The present invention is the same as the flow path 101 of the intake and exhaust duct 100 of the straight pipe 110, "T" shaped pipe 120, "b" shaped pipe 130 and elbow tube 140 as shown in FIG. It is possible to prevent the generation of noise, the change of the flow rate, and the like by forming a plurality of air split inducting membranes 102 having a straight line or a radius of curvature.

The flow path 101 is provided with a plurality of narrow split flow paths 103 divided by the air split inducting film 102 to distribute air through the respective split flow paths 103 and the like. In particular, each intake and exhaust duct 100 in forming the split flow passage 103 in the intake and exhaust duct 100, such as "T" -shaped pipe 120, "A" shaped pipe 130 and elbow pipe 140. In consideration of the radius of curvature of the air-dividing partition between the induction gap 102 is designed by the difference in the fixed interval between the inside and the outside of the radius of curvature, it is possible to distribute the air at a more precise flow rate and flow rate.

As described above, the present invention provides an intake and exhaust duct so as to maintain a constant flow of the air discharged from the ventilation unit in forming the intake and exhaust duct applied to a low or restricted dimension of the dog. By forming a plurality of air splitting inductors on the inner surface of the pipe to secure a split flow path partitioned by each air splitting insulator, the flow rate per unit area of air is increased or decreased, and the flow rate is distributed and distributed to make the flow rate constant. Likewise, noise generated by the difference in flow rate can be reduced, and fresh air in accordance with the design value can be distributed to a desired room with a certain amount of air.
