[0002] At present, the air conditioning and ventilation systems of sports venues are relatively mature and diversified. Such as full air system, fan coil system, direct expansion evaporative system. The full air system is common in that all air supply outlets are evenly arranged above the venue; the fan coil system is a fan coil system that is dispersed around the venue; the direct expansion evaporative system is a variable frequency multi-connected air conditioning unit, and the indoor units are evenly arranged around the venue. The above systems are common air conditioning and ventilation systems in sports venues. However, the arrangement of the air supply and return air outlets of these systems is not suitable for the particularity of the wind speed field requirements of badminton stadiums, that is, the wind speed below 9m in the badminton stadium is required to be ≯0.2m / s, which is also the pain point and difficulty of the design of the air conditioning and ventilation system of badminton stadiums at this stage. Therefore, the air supply and return air outlets of the air conditioning and ventilation system of the badminton stadium must meet the temperature and humidity requirements during use, and must not affect the flight trajectory of the badminton during the game. Therefore, it is necessary to propose a new air conditioning and ventilation structure for badminton stadiums to meet the air supply and return requirements of the air conditioning and ventilation system of badminton stadiums.

[0020] Example

[0021] like Figure 1-2 As shown, this embodiment provides an air conditioning and ventilation structure for a badminton stadium, including an air supply system, a return air system and an exhaust system. The air supply system includes an air supply pipe 1, a lower air supply port 2 and a top air supply port 3; the lower air supply port 2 and the top air supply port 3 are arranged on the air supply pipe 1, the lower air supply port 2 is located in the rest area of ​​the badminton stadium, and the lower air supply port 2 is 2.5m from the ground; the top air supply port 3 is arranged in the roof steel structure truss, and is evenly arranged along the top gap between the two badminton courts; the return air system includes a return air pipe 6, a return air port 7, and a silencing static pressure box 8; the air supply system and the return air system are connected through The combined air conditioner 13 is integrated in the air conditioning room; outdoor fresh air enters through the fresh air duct 14 of the combined air conditioner 13; the indoor return air passes through the return air outlet 7 and the return air duct 6 and then merges with the outdoor fresh air, and is processed by the combined air conditioner 13 to the required air supply state point, and is then delivered into the room through the supply air duct 1; the silencer static pressure box 8 is arranged and connected to the return air duct 6 and the fresh air duct 14; the exhaust system includes an exhaust fan 9, an exhaust duct 10, and an exhaust outlet 12; the exhaust outlet 12 is arranged on the exhaust duct 10, and the exhaust duct 10 is connected to the exhaust fan 9; the exhaust outlet 12 is arranged on the other side away from the return air outlet 7.

[0022] See you next time Figure 1 ; 80% of the air supply in the air supply system is sent to the rest area around the badminton court through the lower air supply port 2; 20% of the air supply is sent to the air above the badminton court through the top air supply port 3.

[0023] See you next time Figure 1 The lower air outlet 2 is a double-layer grid air outlet. The lower air outlet 2 is set in the rest area around the venue, which greatly reduces the impact of wind speed on the badminton court in the middle.

[0024] See you next time Figure 1 , a manual regulating valve 4 is provided on the air outlet duct of the lower air outlet 2 and the top air outlet 3. In order to meet the wind speed of the venue below 9m ≯ 0.2m / s. In order to control the wind speed at the system outlet, a manual regulating valve 4 is provided on the air outlet duct.

A CO2 concentration monitoring device 17 is set in the densely populated area near the return air outlet, which can automatically adjust the fresh air volume according to the density of people in the venue in real time to save air conditioning energy consumption.

[0030] There are two operating modes in the air supply system: 1. Winter and summer air-conditioning seasons, that is: when the fresh air volume meets the hygiene needs of people in the badminton stadium, such as 10% of the air volume of the entire air supply system, the return air volume is 90% of the air volume of the entire air supply system, and the exhaust air volume is 90% of the fresh air volume at this time, in order to maintain a slight positive pressure in the venue and prevent outdoor air from invading; 2. Spring and autumn transition seasons, in order to save energy consumption, directly introduce outdoor fresh air to eliminate excess heat in the badminton stadium, that is, increase the fresh air volume, so that the system can achieve transition season full air operation, at this time the fresh air volume is 70% of the air volume of the entire air supply system, the return air volume is 30% of the air volume of the entire air supply system, and the exhaust air volume is 90% of the fresh air volume.

[0031] The air outlets of the air conditioning and ventilation system of the utility model are reasonably arranged to meet the temperature field and wind speed field requirements of the indoor environment of the badminton stadium; the fresh air is evenly sent into the badminton stadium without affecting the flight trajectory of the badminton during the game.

[0032] The above contents are merely examples of the structure of the present utility model. The technical personnel in the relevant technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the present utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
