Description

Underground air duct system for inflatable membrane building

Technical Field

The utility model relates to a gas film building field especially relates to an underground duct system for inflating membrane building.

Background

The inflatable membrane structure has the advantages of low manufacturing cost, short construction period, convenient installation and removal, large span, good space utilization, energy conservation, environmental protection and the like, and is widely applied to large-space and large-span civil buildings such as playgrounds, exhibition halls and the like. However, in practical engineering application, because the wind pressure and the wind speed of the air supply outlet are too large, the air conditioner and the heater are too intensively utilized insufficiently, fresh air is difficult to flow according to a designed path, air exchange cannot achieve the optimization purpose, so that the experience of internal activity personnel is poor, and certain measures are required to be taken to improve the air state entering the air film building.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the defect of current air film air supply return air, provide an underground duct system for inflating membrane building, reduce supply-air outlet wind pressure wind speed, evenly spread and utilize the air conditioner heating installation, make the new trend flow according to the design route, with the abundant effective exchange circulation of air film building inside air, improve inside activity personnel and experience, underground passage does not occupy personnel's activity space simultaneously.

In order to achieve the above purpose, the technical scheme is as follows.

The utility model discloses an including mechanical unit, highly-compressed air, supply-air outlet, secret air supply channel, the export of supplying air, air film building inner space, the return air entry, secret return air channel, the return air inlet, the check valve, the pressure release wind gap.

The mechanical unit mainly comprises a fan and an air conditioner. The outdoor fresh air can be heated or cooled and then sent out from the air supply outlet by high-pressure air.

And the high-pressure air is sent out from the air supply outlet and enters the underground air supply channel, and the underground air supply channel is built by a reinforced concrete masonry structure. Has the functions of heat preservation, heat insulation, cleaning and sealing, and the air supply path is clear and reliable. The air enters the air film building through a plurality of air supply outlet shutters, and the air speed and the air pressure of the air supply are reduced to the allowable comfortable range.

The air exchanges heat in the internal space of the air film building and flows along the design direction, so that the air provides comfortable experience for internal activity personnel.

The air enters the underground return air channel through the return air inlet shutter, flows through the return air inlet and returns to the mechanical unit.

The check valve may close to prevent return air from returning to the mechanical unit.

The pressure relief air port can be opened to release air when the air pressure difference exceeds the limit, and the protective air film is not broken by the ultrahigh air pressure difference. The structure of the air film building is ensured to be safe and reliable.

The utility model provides an adopt the mode in secret wind channel, realize the improvement of wind pressure, wind speed, temperature, air supply route of air film building air supply.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The utility model provides an underground duct system for air film building. As shown in the attached figure 1, the underground air duct system comprises a mechanical unit 12, a fresh air 1, an air supply outlet 2, an underground air supply channel 3, an air supply outlet 10, an air film building internal space, an air return inlet 11, an underground air return channel 6, an air return opening 7, a check valve and a pressure relief air opening 8.

The mechanical unit sucks external fresh air, the fresh air firstly passes through the filter plate to filter dust and impurities, is refrigerated or heated through an air conditioner or a gas furnace, enters the underground air supply duct from the air supply outlet, enters the air film building inner space from the underground air supply duct to the air supply outlet, flows to the air return inlet in the air film building inner space, enters the underground air return channel, and returns to the mechanical unit through the air return inlet.

The air supplied into the underground air supply duct from the air supply outlet by the mechanical unit is high-pressure high-speed flowing air, and the refrigerated or heated air is insulated in the underground air supply duct and has low energy consumption. The underground air supply duct extends according to a designed path.

The air supply outlet has a plurality ofly, and the air supply gets into inside the air film building through a plurality of air supply outlets, and the wind pressure wind speed all can reduce the designing requirement. The air supply carries out the heat exchange in air film building inner space, gives the comfortable experience of inside activity personnel, and the air continues to flow to the return air entry along the design route.

The air enters the underground return air channel through the return air inlet shutter, and the heat insulation and heat preservation energy consumption of the air in the underground return air channel is low. The return air underground passage returns to the mechanical unit through the return air inlet along a designed path.

The air return port is provided with a check valve, when the air pressure difference inside and outside the air film building is lower than the design requirement, the check valve can be closed, and fresh air is continuously fed into the air film to improve the air pressure difference. After the air pressure difference is ensured, the check valve is opened, and the air inside the air film circularly flows to reduce the energy consumption of the air conditioner heater.

The air film is provided with a pressure relief air port. When the air pressure difference inside and outside the air film building exceeds the design requirement, the pressure relief air opening is opened to release the air inside the air film to the outside. After the air pressure difference is ensured, the pressure relief air port is closed. The safety of the air film building structure is ensured.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
