[0008] One end of the duct is connected to the ventilation louver, and the other end is provided with an adjusting valve. The duct is provided with a fan.

[0009] The purification device has a purification inlet and a purification outlet. The purification inlet is arranged between the fan and the adjusting valve to be connected to the duct. The purification outlet is located below the purification device to supply air to the indoor.

[0010] Further, the ceiling is made of a color-changing material.

[0011] Further, the ceiling is provided with a wind vane at the center.

[0012] Further, the distance between the ceiling and the ground is 1m to 2m.

[0013] Further, the filter screen has a filter hole size of not greater than 1mm.

[0014] With the technical scheme, the application has the following advantages:

[0015] The ventilation structure is added to the traditional light well structure, and the ventilation structure can adjust the start and stop time of the two fans according to the wind direction and wind speed, so that the outdoor air enters the indoor through the purification device, and the indoor air is discharged to the outdoor. The ventilation structure can undertake part of the functions of air conditioning and fresh air of the underground commercial complex, can reduce energy consumption, reduce the layout cost of fresh air air conditioning, and fully utilize the structure of the light well.

[0020] Based on the background art, referring to the drawings Figure 1 The application provides a ventilation and light well structure suitable for an underground commercial complex, which comprises a ceiling 1, an aboveground structure and an underground structure from top to bottom. The aboveground structure comprises ventilation structures symmetrically arranged in the east-west and / or north-south directions. The ventilation structures comprise, from outdoor to indoor, in sequence:

[0021] A filter screen 3 located outdoors, which is connected with the ceiling 1 and arranged below the ceiling 1;

[0022] A ventilation louver 2, the opening of which is adjustable and extends from outdoor to indoor;

[0023] An air pipe 5, one end of which is connected with the ventilation louver 2, and the other end is provided with a regulating valve 6. The air pipe 5 is provided with a fan 7.

[0024] A purification device 4, which has a purification inlet and a purification outlet. The purification inlet is arranged between the fan 7 and the regulating valve 6 to be connected with the air pipe 5. The purification outlet is located below the purification device 4 to supply air to the indoor.

[0025] The ground structure is the part above the ground, and the underground structure is the part into the commercial complex. In the ground structure, the ventilation structure is symmetrically arranged in the east-west direction or the north-south direction, or arranged in both the east-west direction and the north-south direction, and when arranged, the ventilation structures in the east-west direction are symmetric to each other, and the ventilation structures in the north-south direction are symmetric to each other.

[0026] The ventilation louver 2 of the present application is adjustable in opening degree, and the ventilation volume increases as the opening degree increases, and the ventilation volume decreases as the opening degree decreases. The purification device 4 is a prior art, which can purify the air in the air pipe 5 and discharge it to the indoor through the purification outlet. The regulating valve 6 is arranged at the end of the air pipe 5 close to the indoor, which can adjust the air flux.

[0027] In the present application, the fans 7 in different directions are started and stopped according to the wind direction, and the principle is to ensure that the outdoor air measured by the windward side enters the indoor through the purification device 4, and the indoor air is discharged to the outdoor through the leeward side. The specific implementation is as follows:

[0028] In the windward measurement, the fan 7 and the regulating valve 6 are closed, the outdoor air flux is controlled by adjusting the ventilation louver 2, and the purified air is supplemented into the indoor by opening the purification device 4. In the leeward side, the purification device 4 is closed, the regulating valve 6 and the fan 7 are opened, and the dirty air rising with the hot air is discharged to the outdoor.

[0029] In the specific implementation, a temperature sensor 9 can be arranged in the indoor, and the temperature sensor 9 is different from the design temperature of the indoor. If the temperature measured by the temperature sensor 9 is higher than the design temperature, the opening degree of the ventilation louver 2 is increased, and the outdoor air is introduced into the indoor. Otherwise, the opening degree is reduced to reduce the heat loss caused by ventilation and air exchange.

[0030] As a preferred embodiment of the present application, the manufacturing material of the ceiling 1 is a variable color material. The variable color material ceiling 1 can be realized according to the prior art, for example, the glass containing silver bromide (or silver chloride) and trace copper oxide.

[0031] As a preferred embodiment of the present application, the center of the ceiling 1 is provided with a wind direction instrument 8. The wind direction instrument 8 can indicate the wind direction at the ceiling 1, and the center position of the ceiling 1 is more accurate.

[0032] As a preferred embodiment of the present application, the distance range of the ceiling 1 above the ground is 1m~2m.

[0033] As a preferred embodiment of the present application, the filter hole size of the filter screen 3 is not greater than 1mm. The filter hole size should not be too large, because the height of the light well is not high, and it is necessary to prevent mosquitoes from blocking the filter hole.

[0034] The places not mentioned in the present application can be realized by using or referring to the existing technology.

[0035] The above merely provides an example of the present application, but is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the scope of claims of the present application.
