[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is mainly divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system is more suitable for industrial or large-area office areas due to its large engineering volume, while the ductless fresh air system is more suitable for home use due to its easy installation.

[0003] Currently, traditional underground garages typically use exhaust fans to extract stale air from the garage, or supply fans to deliver fresh air to the garage. However, simply supplying or exhausting air to the garage results in poor ventilation efficiency and effectiveness. This is particularly true for garages with a high volume of vehicles entering and exiting. Stale air cannot be quickly expelled, impacting the air quality of the garage, and this needs improvement.

DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below with reference to the accompanying drawings.

[0035] Reference Figure 1 、 Figure 2A fresh air system for an underground garage includes an air supply mechanism 1 and an exhaust mechanism 2. The air supply mechanism 1 includes an air supply main pipe 11, an air supply pipe group 12, and multiple air supply branch pipes 13. The air supply main pipe 11 can pass through the floor of the underground garage and be fixedly connected to an external blower. The air supply pipe group 12 is fixedly connected to the bottom of the air supply main pipe 11 and can be fixedly connected to the floor of the underground garage. Multiple air supply branch pipes 13 are respectively vertically connected to the bottom of the air supply pipe group 12, and the air supply branch pipes 13 can be fixedly connected to the walls or columns of the underground garage. At the same time, each air supply branch pipe 13 is connected to an air supply nozzle 14 at the bottom.

[0036] Reference Figure 1 、 Figure 3 The exhaust mechanism 2 includes an exhaust main pipe 21, an exhaust pipe group 22 and a plurality of exhaust branch pipes 23. The exhaust main pipe 21 can pass through the floor slab at the top of the underground garage and be fixedly connected to the external exhaust fan. The exhaust pipe group 22 is fixedly connected to the bottom of the air supply main pipe 11, and the exhaust pipe group 22 can be fixedly connected to the floor slab at the top of the underground garage, and a plurality of exhaust branch pipes 23 are respectively fixedly connected to the exhaust pipe group 22.

[0037] Reference Figure 1 、 Figure 4 Multiple air supply branch pipes 13 and multiple exhaust branch pipes 23 are arranged in a matrix shape. The bottom end of the air supply branch pipe 13 is lower than the exhaust branch pipe 23, that is, the bottom end of the exhaust branch pipe 23 is closer to the top of the underground garage, and the bottom end of the air supply branch pipe 13 is closer to the ground of the underground garage.

[0038] Fresh air is delivered to the main air supply pipe by an external blower. The air then enters the air supply pipe assembly 12, then flows into multiple air supply branches 13, and finally enters the underground garage through multiple air supply nozzles 14. Turbid air in the underground garage flows through multiple exhaust branches 23 and enters the exhaust pipe assembly 22. The air is then exhausted through the main exhaust pipe 21 by the external exhaust blower, thus achieving ventilation in the underground garage.

[0039] The air supply mechanism 1 and exhaust mechanism 2 of the fresh air system of this application cooperate and work together to deliver fresh air to the underground garage while simultaneously extracting and discharging stale air, thereby improving ventilation efficiency and ensuring effective ventilation. Simultaneously, fresh air enters the underground garage at the bottom floor through the air supply nozzle 14, while the exhaust branch pipe 23 is located at the top floor of the underground garage. The fresh air pushes in and the exhaust branch pipe 23 extracts stale air from the underground garage upward, allowing it to be quickly discharged through the exhaust branch pipe 23, thereby improving ventilation in the underground garage.

[0040] Reference Figure 4 、 Figure 5The air supply nozzle 14 includes an air supply tube 141 and multiple air supply nozzles 142. The top of the air supply tube 141 is connected to the air supply branch pipe 13 and the bottom is sealed. The multiple air supply nozzles 142 are fixedly connected to the side walls of the air supply tube 141 and are arranged at equal intervals along the circumference of the air supply tube 141 to increase the air supply area. At the same time, the air supply nozzles 142 are arranged at an upward angle so that fresh air can push the turbid air upward, allowing the turbid air to be discharged quickly.

[0041] Reference Figure 4 、 Figure 5 The air supply tube 141 is rotatably connected to the air supply branch pipe 13 via a sealed bearing. A spiral control plate 143 is fixedly connected to the inner wall of the air supply tube 141, and multiple air supply nozzles 14 are located below the control plate 143. When air flows through the control plate 143, the air supply tube 141 can rotate to increase the air supply area, allowing fresh air to be distributed to more locations and improving the ventilation effect.

[0042] Reference Figure 1 、 Figure 2 The air supply pipe group 12 includes multiple horizontally and parallelly arranged first air supply pipes 121. Both ends of each first air supply pipe 121 are sealed, and the air supply main pipe 11 is connected to one of the first air supply pipes 121. Every two adjacent first air supply pipes 121 are connected by multiple horizontally and parallelly arranged second air supply pipes 122. The multiple first air supply pipes 121 and the multiple second air supply pipes 122 form a grid structure, and the multiple exhaust branch pipes 23 are respectively located at the corresponding mesh positions of the grid structure.

[0043] Reference Figure 1 、 Figure 3 The exhaust duct group 22 includes multiple horizontally and parallelly arranged first exhaust ducts 221. Both ends of each first exhaust duct 221 are sealed, and the exhaust main duct 21 is connected to one of the first exhaust ducts 221. Every two adjacent first exhaust ducts 221 are connected by multiple horizontally and parallelly arranged second exhaust ducts 222. The multiple first exhaust ducts 221 and the multiple second exhaust ducts 222 form a grid structure. Multiple exhaust branch ducts 23 are respectively connected to corresponding first exhaust ducts 221.

[0044] Reference Figure 1 、 Figure 2 、 Figure 3 , multiple first exhaust ducts 221 are respectively located directly above the corresponding first supply air ducts 121, and the first exhaust ducts 221 are connected to the corresponding first supply air ducts 121 through reinforcing columns 3 to improve the connection stability between the air supply mechanism 1 and the exhaust mechanism 2, while also improving the structural strength of the pipeline to ensure the stability of the fresh air system.

[0045] In this embodiment, the fresh air system also includes a controller and multiple carbon dioxide sensors. The controller is connected to an external supply fan, an exhaust fan, and the multiple carbon dioxide sensors. When the carbon dioxide gas in the underground garage exceeds a preset value of the carbon dioxide sensors, it indicates that the underground garage needs to be ventilated. At this time, the carbon dioxide sensors transmit a detection signal to the controller, which controls the external supply fan and exhaust fan to start simultaneously, thus achieving automated ventilation.

[0046] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
