[0002] The design of smoke exhaust system in tall spaces or atriums of buildings is an important part of ensuring fire safety and comfortable environment of buildings. Smoke can be discharged through natural or mechanical exhaust methods. Mechanical smoke exhaust fans have large air volume and loud noise when working, and do not meet the comfort requirements when turned on. In a sense, it is a waste of building resources; natural smoke exhaust and air supply are achieved through indoor thermal pressure and wind pressure, which does not consume artificial energy, is economical and green, and improves the utilization rate of smoke exhaust systems, and saves the design cost of natural ventilation systems. It is a good energy-saving ventilation measure.

[0003] The existing natural ventilation system has the following shortcomings:

[0004] (1) The air supply windows and smoke exhaust windows of the existing natural smoke exhaust and air supply system are usually set on the exterior wall of the building. The shape of the exterior wall is affected by the area and position of the smoke exhaust window and air supply window, and the shape design of the exterior wall of the building is more restricted;

[0005] (2) The air supply windows and smoke exhaust windows of the existing natural smoke exhaust and air supply systems are usually set at adjacent heights, resulting in the problem of indoor smoke accumulation in the space and difficulty in exhausting. The air supply windows and smoke exhaust windows of some natural smoke exhaust and air supply systems are also set on the same side, resulting in a short gas flow path formed by air supply and smoke exhaust, and a poor smoke exhaust effect.

[0017] Preferably, a floor cover plate is provided above the floor air supply window, and the floor cover plate comprises a ventilated floor grille cover plate.

[0018] Preferably, the floor cover is openable.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. This utility model optimizes the design of natural smoke exhaust and air supply facilities by adding them to the fire linkage system. The atrium or large space can achieve natural ventilation through indoor heat pressure and wind pressure, which does not consume artificial energy, is economical and green, and improves the utilization rate of the smoke exhaust system. It is a good energy-saving ventilation measure.

[0021] 2. The utility model adopts the design of top smoke exhaust window and floor air supply window electrically connected to the indoor fire linkage system. The top smoke exhaust window and floor air supply window are respectively located at the top and bottom of the indoor space, which is conducive to improving the efficiency of smoke exhaust in the indoor space and reducing the probability of smoke accumulation;

[0022] 3. The utility model is conducive to expanding the flow path of gas and improving the smoke exhaust effect by arranging the top smoke exhaust window and the floor air supply window on both sides of the atrium or tall space;

[0023] 4. The utility model arranges the top smoke exhaust window on the back of the parapet and the floor air supply window on the floor slab instead of on the exterior wall of the building. Therefore, the top smoke exhaust window and the floor air supply window cannot be seen from the exterior wall of the building, and the shape of the exterior wall of the building is not affected by the area and position of the smoke exhaust window and the air supply window, which is conducive to the freedom of design of the building's facade.

[0031] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0032] like Figure 1 As shown, a natural smoke exhaust and air supply system provided by the utility model includes a top smoke exhaust window 1 and a floor air supply window 4. The top smoke exhaust window 1 is arranged on the back of the roof parapet, and the top smoke exhaust window 1 is electrically connected to the fire linkage system. The floor air supply window 4 is arranged on the indoor floor slab under the atrium or the tall space, and the floor air supply window 4 is electrically connected to the fire linkage system. The top smoke exhaust window 1 and the floor air supply window 4 are respectively projected on both sides of the atrium or the tall space.

[0033] The utility model adopts a top smoke exhaust window 1 linked with the fire protection arranged on the back of the roof parapet and a floor air supply window 4 linked with the fire protection arranged on the indoor floor slab, thereby providing a hidden natural smoke exhaust and air supply method for an atrium or a tall space, avoiding the influence of setting external windows on the building facade on the shape of the building facade, thereby providing freedom in the design of the building facade, and achieving a better aesthetic design effect.

[0034] The utility model adopts the design of the top smoke exhaust window 1 and the floor air supply window 4 electrically connected to the fire linkage system. The top smoke exhaust window 1 and the floor air supply window 4 are respectively located at the top and bottom of the indoor space. The outdoor fresh air enters the tall space through the floor air supply window 4, which strengthens the movement of the hot air in the tall space from bottom to top. Under the joint action of heat pressure and wind pressure, the hot air in the tall space is discharged to the outdoor roof to achieve the purpose of natural ventilation, thereby improving the smoke exhaust efficiency in the indoor space and reducing the probability of smoke accumulation. Furthermore, the top smoke exhaust window 1 and the floor air supply window 4 are respectively projected on both sides of the floor atrium. The air entering from bottom to top through the floor air supply window 4 flows through the floor atrium and is then discharged from the rooftop smoke exhaust window, which is conducive to expanding the gas flow path and improving the smoke exhaust effect.

[0035] Specifically, when there is a need for smoke exhaust in the interior space of the building, the top smoke exhaust window 1 and the floor air supply window 4 are opened at the same time under the control of the fire linkage system. The fire linkage system controls the simultaneous opening of the top smoke exhaust window 1 and the floor air supply window 4 through an electric one-button control. The fire linkage system is set up indoors and is an important part of the automatic fire alarm system. The opening angle of the top smoke exhaust window 1 is ≥70°, and a protective railing 2 is set on the inner side of the top smoke exhaust window 1. When the top smoke exhaust window 1 is opened, the protective railing 2 can play a safety protection role. A decorative ceiling 3 is set in the upper cavity next to the top smoke exhaust window 1. The decorative ceiling 3 includes a ventilated decorative grille ceiling, which can meet the design requirements of the ventilation volume.

[0036] Specifically, the floor air supply window 4 includes a plurality of floor air supply windows 4, which are respectively arranged at different floor plates. An anti-falling net 5 and an aluminum plate ceiling 6 are arranged in sequence below the floor air supply window 4, and the aluminum plate ceiling 6 is provided with ventilation perforations to meet the design requirements of the ventilation volume. A floor cover plate 7 is arranged above the floor air supply window 4, and the floor cover plate 7 can be opened. The floor cover plate 7 includes a ventilated floor grille cover plate, and the pressure bearing capacity of the floor cover plate 7 meets the requirements of the floor load design.
