2 to 6, the building ventilation system 100 according to a preferred embodiment of the present invention is provided with a floating floor structure 10, the support 20 and the outside air inlet means.

The building 9, in which the building ventilation system 100 according to the present invention is used, is disposed in a vertical direction and horizontally between the building outer wall 1 and the building outer wall 1 forming a constant space therein. It is provided with the slab bottom body 2 arrange | positioned and the inner wall 3 arrange | positioned in the vertical direction between the said building exterior wall 1. In the case of a multi-story building, the slab floor 2 forms one floor. In addition, the inner wall 3 divides the interior space formed on the slab bottom 2.

The floating floor structure 10 has been used in recent years as a structure developed to reduce the interlayer noise due to the heavy impact sound. In the conventional building, a heating water pipe is disposed on the slab bottom 2 and a mortar layer is stacked thereon. However, in this case, noise and vibration due to heavy impact sound generated in the upper floor are transmitted to the lower floor. . In order to solve this problem, various interlayer noise reduction materials were laminated, but the noise reduction effect was not excellent. Accordingly, a so-called floating floor structure was introduced to separate the floor of the indoor space from the slab bottom 2. The building ventilation system 100 according to the present invention is used for such floating floor structure. In the building ventilation system 100 according to the present invention, the floating floor structure 10 is spaced about 50 mm to 100 mm upward from the slab bottom body 2, and the floating floor structure 10 is a slab bottom body ( It is arranged in the horizontal direction parallel to 2). Thus, a predetermined space c is formed between the slab bottom 2 and the floating bottom structure 10.

On the other hand, the floating floor structure 10 is formed in a multi-layer, the board 11 is formed in a plate shape on the bottom layer. As for this board 11, a so-called particle board known in the art is generally used. On the upper side of the plate-shaped board 11, plywood 12 is laminated. The plywood 12 is made of wood of a predetermined thickness. The heating panel 13 is stacked on the plywood 12. This heating panel 13 is also known as a hot water ondol panel as a known member. An accommodating groove 18 is formed above the heating panel 13 to accommodate and fix the heating water pipe 19 to be described later. The accommodating groove 18 is arranged in the heating panel 13 to freeze like a mesh so as to freely arrange the heating water pipe 19.

The heating water pipe 19 is used to circulate hot water to heat the interior space of the building 9 and is connected to a hot water system including a boiler (not shown), a pump (not shown), and the like. That is, both ends are connected to the hot water system so as to be circulated. The heating water pipe 19 is preferably arranged in a zigzag shape in the indoor space so as to ensure sufficient heat transfer area and heat transfer time of the indoor space. In the present invention, the heating water pipe 19 is fitted into the receiving groove 18 of the heating panel 13 is fixed. However, it is not completely impossible to be separated, it is detachably fitted in the receiving groove 18 so that the arrangement can be changed according to the heating plan.

The finishing material 14 is stacked on the heating panel 13. The finish 14 may be formed of various materials, such as tiles, parquet or flooring, depending on the purpose of the building.

When hot water is circulated through the heating water pipe 19 in the floating floor structure 10 having the above-described structure, the heat of the hot water is transferred not only to the interior space through the finishing material 14, but also to the plywood 12. And the particle board 11 are also transferred to the space c between the slab bottom 2 and the floating bottom structure 10.

The support 20 is for supporting the floating bottom structure 10 with respect to the slab bottom 2, and is disposed between the floating bottom structure 10 and the slab bottom 2. The support 20 is arranged in a plurality of checker board form a plurality of spaced apart from each other at regular intervals. The height of the support 20 is approximately 50mm to 100mm, has a cross-section of approximately 'I' shape, it is preferable that the high-strength metal material.

The outside air inlet means is for introducing outside air into the indoor space, and includes an air inlet duct 30 and a blowing fan 40. The air inlet duct 30 is to introduce external air from the outside of the building into the interior space of the building 9, and is installed in the space c between the slab floor 2 and the floating floor structure 10. . Accordingly, both ends of the air inlet duct 30 are opened, one end thereof is in communication with the outside of the building 9 to form an inlet 31, and the other end thereof is in communication with the interior space of the building 9. The outlet 34 is formed. In this embodiment, the path of the air inlet duct 30 starts from the outer wall 1 of the building and passes between the slab floor 2 and the floating floor structure 10 to the inner wall of the building 9 ( Follow 3) upwards to finish. That is, the inlet 31 of the air inlet duct 30 is installed in the lower portion of the interior space near the building exterior wall 1 and the outlet 34 is installed in the interior wall 3 of the building and disposed above the interior space.

In this embodiment, the air inlet duct 30 is described and illustrated as being disposed inside the building inner wall 3. However, the present invention is not limited thereto, and the air inlet duct 30 may be installed outside the inner wall 3 instead of the inner wall 3 of the building, that is, installed in the indoor space and disposed along the inner wall 3. Where the inner wall is not provided, such as may be arranged along the pillar or outer wall. In summary, since the air inlet duct 30 is for introducing external air from outside the building between the slab bottom 2 and the floating bottom structure 10, the air inlet duct 30 is the dominant slab bottom ( Once disposed between the 2) and the floating floor structure 10, the path to be discharged to the interior space thereafter can be variously arranged according to the building.

In addition, in order to ensure good heat transfer from the heating water pipe 19 to the air inlet duct 30, that is, in order to ensure a heat transfer area and a heat transfer time, the air inlet duct 30 is connected to the heating water pipe 19. ) Is preferably arranged in a zigzag shape along the arrangement.

On the other hand, the inlet 31 is generally provided with a grill (33, grille), to prevent a certain volume or more of the toilet paper or dirt to enter the air inlet duct (30). In addition, the filter 32 is installed behind the inlet 31 of the air inlet duct 30 on the flow path of the outside air to be introduced. The filter 32 is for filtering out dust particles, contaminants, and the like in the introduced outside air, and various known filters may be used.

The blowing fan 40 is for forcibly inflowing and transporting outside air outside the building 9, and more specifically, is disposed at the rear of the filter 32 toward the inlet 31 of the air inlet duct 30. When power is applied to the blower fan 40, the air outside the building is forced to the air inlet duct 30.

The rear of the blowing fan 40 is provided with a sound absorbing material 35 to reduce the noise caused by the flow of the outside air. The sound absorbing material 35 may be a known material having a cushioning property such as a sponge, etc., and is attached to the inner surface of the air inlet duct 30. However, the sound absorbing material 35 is not attached over the entire length of the air inlet duct 30, but is attached only to the rear part of the blowing fan 40. At the portion where the sound absorbing material 35 is attached, the air inflow cross-sectional area of the air inlet duct 30 is less than the rear of the portion where the sound absorbing material 35 is not attached, that is, the portion where the sound absorbing material 35 is attached on the flow path of the outside air. Widely formed

On the other hand, the outer wall (1) of the building is provided with an exhaust port 7 so that the air in the interior space can be discharged to the outside.

Hereinafter, a use example of the building ventilation system 100 according to a preferred embodiment of the present invention will be described.

After installing the building ventilation system 100 having the above configuration in a building, when power is supplied to the blowing fan 40, the air outside the building 9 is aired through the grill 33 installed in the inlet 31. It is introduced into the inlet duct 30. At this time, dirt or more of a certain volume such as a tissue is prevented from flowing into the air inlet duct 30 over the grill 33. The outside air introduced in this way is filtered through the filter 32 and passes through the blowing fan 40. At this time, the noise generated as the outside air is forcedly compressed by the blowing fan 40 is reduced by the sound absorbing material 35 disposed behind the blowing fan 40 so that the noise is not transmitted to the indoor space. The outside air passing through the portion where the sound absorbing material 35 is attached passes through the slab bottom 2 and the floating bottom structure 10, and then rises along the inner wall of the building 9, through the outlet 34, and the building 9. It is supplied to the indoor space of the ventilation is carried out.

On the other hand, in winter, the warm air must be introduced into the indoor space by heating the introduced outdoor air. Conventionally, a separate heater is installed to heat the introduced air, but in the present invention, the heated water pipe 19 disposed above the air inlet duct 30 while the introduced air passes through the air inlet duct 30. It is heated by the advantage that there is no need for a separate heater. When the air is continuously introduced into the indoor space, the air in the indoor space is discharged to the outside through the exhaust port 7 installed in the outer wall 1 of the building, whereby ventilation is performed.

In the ventilation system 100 according to the present invention, not only floor noise, which is an advantage of the building of the floating floor structure, is reduced, but also the conventional floating floor structure building by using the lower space of the floating floor structure 10 in the floating floor structure. By installing the duct in the ceiling space like the ventilation system of the problem does not occur the height of the indoor space is lowered, there is an advantage that can utilize the space optimally. In addition, since there is no need for a separate heater as in the conventional ventilation system, there is an advantage that the energy consumption is reduced.
