[0001] The present application relates to the technical field of basement ventilation, and in particular to an air supply system. Background Art

[0002] The total number of cars in cities is increasing, but the number of parking lots is insufficient to provide enough parking spaces. The phenomenon of "difficult driving and parking" in cities has become very common. Therefore, making full use of underground space to build parking lots plays an important role in alleviating urban road congestion. Underground parking lots are characterized by high construction costs and long construction periods. In order to improve the capacity of underground parking lots and reduce the construction cost of a single parking space, underground parking lots often have two, three, or even more underground floors.

[0003] However, underground parking lots are difficult to be exposed to direct sunlight, and they are relatively closed and airtight, so underground parking lots are prone to breeding bacteria and fungi, posing a threat to the health of people in the garage. The traditional method of disinfecting underground parking lots is to manually spray disinfectant regularly or install disinfection lamps in the underground parking lot. The manual spraying method is inefficient and has high labor costs, and the underground parking lot needs to be closed during spraying. The installation of disinfection lamps will reduce the disinfection efficiency due to the poor air circulation in underground parking lots. In addition, the underground parking lot has a large space, and the disinfection lamps not only consume a lot of electricity, but also are difficult to disinfect effectively. Summary of the invention

[0030] Referring to FIG. 1 , FIG. 1 shows a schematic diagram of an air supply system in an embodiment of the present application. The air supply system provided in an embodiment of the present application includes an air supply fan 10, an air duct 20, a plurality of purifiers 30, and a controller 40. The air duct 20 is connected to the air supply fan 10, and a plurality of light-transmitting windows (not shown) are formed at intervals on the wall of the air duct 20; the purifier 30 is arranged corresponding to the light-transmitting window to sterilize and disinfect the airflow in the air duct 20; the controller 40 is electrically connected to the air supply fan 10 and the purifier 30, and the controller 40 is used to make the air supply fan 10 and the purifier 30 in an on state or in a off state at the same time.

[0031] The air supply system involved in the present application, by setting the purifier 30 corresponding to the light-transmitting window, allows the airflow in the air duct 20 in the underground parking lot to be affected by the sterilization and disinfection effect of the purifier 30, and then allows the clean air after sterilization and disinfection to convect in the underground parking lot, thereby improving the air quality without affecting the resistance coefficient of the air supply fan 10; on the other hand, by setting a controller 40 to control the air supply fan 10 and the purifier 30 to be turned on or off in conjunction, the disinfection efficiency is improved and the energy consumption is reduced.

[0032] Specifically, the air supply system described in the present application can be used in confined spaces such as garages, basements, and operating rooms. In this embodiment, a light-transmitting window is provided on the wall of the air duct 20, and the purifier 30 is arranged opposite to the light-transmitting window. In other embodiments, the air duct 20 is provided with a plurality of air outlets, which also serve as light-transmitting windows, and the purifier 30 directly sterilizes and disinfects the air discharged from the air outlets.

[0033] In some embodiments, the purifier 30 includes an ultraviolet lamp and / or a photocatalyst lamp. The ultraviolet lamp can emit ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA or RNA in the cells of microorganisms to cause cell death, thereby achieving the purpose of sterilization and disinfection. The photocatalyst lamp has a strong oxidation effect. While efficiently killing bacteria and viruses, it also has an oxidation and elimination function for odorous substances to eliminate odors.

[0034] In some embodiments, the air duct 20 is provided with a plurality of quartz glass sheets 21, and the plurality of quartz glass sheets 21 respectively cover a plurality of light-transmitting windows. Exemplarily, referring to FIG. 2 , the light-transmitting windows are all provided on the wall of the air duct 20. The quartz glass sheets 21 are inlaid at the light-transmitting windows and cover the entire light-transmitting windows, so that the air duct 20 is in a closed state at the light-transmitting windows, and the airflow in the air duct 20 does not flow out through the light-transmitting windows, thereby preventing the air in the air duct 20 from flowing out of the air duct 20 without being fully purified.

[0035] The light-transmitting window is rectangular, and corresponding to the light-transmitting window, the quartz glass sheet 21 is also rectangular, so that the rectangular quartz glass sheet 21 and the rectangular light-transmitting window are easier to align, more firmly installed, and have a better fixing effect. In other embodiments, the light-transmitting window and the quartz glass sheet 21 can also be circular, elliptical, polygonal or other shapes.

[0036] Quartz glass has good light transmittance, and has good light transmittance in the entire spectrum band from ultraviolet to infrared. In the ultraviolet spectrum region, the maximum transmittance can reach more than 80%. The use of quartz glass sheet 21 to cover the light-transmitting window reduces the blocking and absorption of ultraviolet rays, so that the sterilizer can provide a stronger disinfection and sterilization effect on the airflow in the air duct 20.

[0037] In some embodiments, the air supply system further includes an electric air valve 50, which is disposed in the air duct 20, and the controller 40 is electrically connected to the electric air valve 50 to control the wind speed in the air duct 20. The controller 40 is also used to control the power of the purifier 30 according to the wind speed in the air duct 20. Exemplarily, referring to FIG. 1 and FIG. 2, the electric air valve 50 is electrically connected to the controller 40 and is controlled by the controller 40. Therefore, the controller 40 can control the wind speed in the air duct 20 by controlling the working power of the blower 10 and the opening and closing degree of the electric air valve 50. At the same time, since the air duct 20 has a certain length, the wind speed at different positions of the air duct 20 is different. The controller 40 can also control the power of the purifier 30 according to the wind speed in the air duct 20, so as to realize the self-adaptation of the power of the purifier 30 to different wind speeds, which can reduce energy consumption and ensure that the best sterilization effect can be provided at different wind speeds.

[0038] In some embodiments, referring to FIG. 2 , the air duct 20 is a square tube, the light-transmitting window is arranged on the side of the air duct 20 away from the ground, and the purifier 30 is arranged above the light-transmitting window. It can be understood that the purifier 30 can sterilize and disinfect the airflow in the air duct 20 through the light-transmitting window, and can also sterilize and disinfect the air around the purifier 30. The light-transmitting window is arranged on the side of the air duct 20 away from the ground, and the purifier 30 is arranged above the light-transmitting window, so that the purifier 30 is at a higher height, and can sterilize and disinfect the air in a larger range, and is farther away from the human body, reducing the adverse effects of the purifier 30 on the human body.

[0039] In some embodiments, the controller 40 is a PLC (Programmable Logic Controller), and the blower 10, the purifier 30 and the electric air valve 50 are electrically connected to the controller 40 through a signal line or a Bluetooth communication module. Specifically, in this embodiment, the blower 10 and the purifier 30 are connected to the PLC through a cable, and the PLC is pre-loaded with an operating program. When the air supply system is running, the purifier 30 is first started to disinfect and sterilize the air in the air duct 20 to improve the air cleanliness in the air duct 20, and then the blower 10 is started to blow the clean air in the air duct 20 out through the air outlet of the air duct 20. After that, the blower 10 continues to supply air to the air duct 20, and the PLC also continues to sterilize and disinfect the airflow in the air duct 20. In the process of supplying air, the PLC controls the opening of the electric air valve 50 according to the actual situation in the confined space to control the airflow rate. When the air supply system needs to be shut down, the blower 10 is shut down first, and the purifier 30 is shut down after a delay of 15 seconds, so that the remaining air in the air duct 20 is also fully purified, further improving the cleanliness of the air in the enclosed space. In other embodiments, the blower 10 and the purifier 30 can also be wirelessly connected to the controller 40 via a Bluetooth communication module, which is more convenient for maintenance.

[0040] In some embodiments, the air duct 20 includes an air supply main pipe 22 and a plurality of air outlet branches 23, and each air outlet branch pipe 23 corresponds to at least one light-transmitting window. Referring to FIG. 2 , in this embodiment, a plurality of light-transmitting windows are provided on the air supply main pipe 22, and are spaced apart from the air outlet branch pipe 23, and a plurality of purifiers 30 sterilize and disinfect the airflow in the air supply main pipe 22 through a plurality of light-transmitting windows. In some other embodiments, at least one light-transmitting window is provided on each air outlet branch pipe 23, and a plurality of purifiers 30 sterilize and disinfect the airflow in the air outlet branch pipe 23 through a plurality of light-transmitting windows. In this way, before the airflow is discharged through the plurality of air outlet branch pipes 23, it is sterilized and disinfected by the purifier 30, thereby maximizing the cleanliness of the airflow.

[0041] In some embodiments, the air volume of the blower 10 is 5000m3 / h ~35000m 3 In this way, the air volume provided by the blower 10 can make the air in the enclosed space fully convective, and the air volume does not exceed the purification power of the purifier 30, and can be fully purified by the purifier 30 to achieve the best purification state of the air in the enclosed space.

[0042] In some embodiments, the air supply system further includes a static pressure box 60, which is connected to the air duct 20. The air blown by the blower 10 passes through the static pressure box 60 and is blown out from the air outlet of the air duct 20. The static pressure box 60 is a device that allows air flow to pass through and can effectively prevent or weaken the propagation of sound energy outward. The static pressure box 60 can reduce dynamic pressure, increase static pressure, stabilize air flow and reduce air flow vibration, so that the air supply effect is more ideal.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
