[0046] See also Figure 1-2 , a gymnasium ventilation system provided by an embodiment of the present application, comprising: a natural ventilation structure 1, a mechanical ventilation structure 2, an air conditioning system 4, a control device 5 and a detection device;

[0047] The detection device includes a wind speed sensor 8, a plurality of temperature sensors 6, and a plurality of humidity sensors 7. The plurality of temperature sensors 6 and the plurality of humidity sensors 7 are respectively arranged outdoors and indoors of the gymnasium to monitor the temperature and humidity indoors and outdoors of the gymnasium. The wind speed sensor 8 is arranged inside the gymnasium to monitor the ground wind speed inside the gymnasium.

[0048] The natural ventilation structure 1, the mechanical ventilation structure 2 and the air conditioning system 4 are respectively arranged in the gymnasium;

[0049] The control device 5 is electrically connected to the natural ventilation structure 1, the mechanical ventilation structure 2, the air conditioning system 4 and the detection device respectively, and the control device 5 is configured to:

[0050] Acquire the outdoor actual temperature and outdoor actual humidity of the gymnasium detected by the temperature sensor 6 and the humidity sensor 7;

[0051] Determine whether the outdoor actual temperature, the outdoor actual humidity, the indoor actual temperature, and the indoor actual humidity meet the comfort requirements;

[0052] According to the judgment result, the opening and closing of the air-conditioning system 4, the natural ventilation structure 1 and the mechanical ventilation structure 2 are adjusted.

[0053] In this embodiment, the control device 5 is used to determine whether the real-time temperature and humidity outside the gymnasium meet the comfort requirements inside the gymnasium, thereby controlling the opening and closing of the air-conditioning system 4 and the natural ventilation system so that the temperature and humidity inside the gymnasium meet the comfort requirements, which is beneficial to reducing air-conditioning energy consumption and saving energy and reducing emissions.

[0054] Furthermore, adjusting the opening and closing of the air conditioning system 4, the natural ventilation structure 1 and the mechanical ventilation structure 2 according to the judgment result specifically includes:

[0055] When the actual outdoor temperature and the actual outdoor humidity do not meet the comfort requirements,

[0056] S1, turning on the air conditioning system 4;

[0057] S2, obtaining the actual indoor temperature and actual indoor humidity of the gymnasium detected by the temperature sensor 6 and the humidity sensor 7;

[0058] S3, when the actual indoor temperature and the actual indoor humidity do not meet the comfort requirement, adjusting the opening degree of the air conditioning system 4 until the comfort requirement is met;

[0059] When the actual outdoor temperature and the actual outdoor humidity meet the comfort requirements, the natural ventilation structure 1 is opened.

[0060] In this embodiment, when the temperature and humidity outside the gymnasium do not meet the comfort requirements inside the gymnasium, the control device 5 controls the air-conditioning system 4 to turn on, and determines whether the comfort requirements inside the gymnasium are met by monitoring the temperature and humidity inside the gymnasium, and adjusts the working mode and temperature of the air-conditioning system 4; when the temperature and humidity outside the gymnasium meet the comfort requirements inside the gymnasium, the control device 5 controls the natural ventilation structure 1 to turn on, without consuming air-conditioning energy.

[0061] Furthermore, after the step of opening the natural ventilation structure 1, the method further includes:

[0062] Obtaining the actual ground wind speed of the gymnasium detected by the wind speed sensor 8, and determining the difference between the actual ground wind speed and the preset wind speed;

[0065] When the actual indoor temperature and the actual indoor humidity do not meet the comfort requirements, the mechanical ventilation structure 2 is turned on and its opening is adjusted until the comfort requirements are met.

[0066] Because badminton halls and other places in the gymnasium have certain requirements for wind speed, after determining that the temperature and humidity outside the gymnasium meet the comfort requirements inside the gymnasium and turning on the natural ventilation structure 1, it is also necessary to compare the actual ground wind speed monitored with the preset wind speed, and control the ground wind speed in the gymnasium by adjusting the opening of the natural ventilation structure 1 to meet the wind speed requirements for sports such as badminton.

The opening and closing and the opening degree of each ventilation structure can be better regulated by the actuator 9, thereby improving the response speed of the system.

[0068] Furthermore, it also includes a mechanical ventilation and fire smoke exhaust structure 3, which is arranged in the gymnasium and is electrically connected to the control device 5. When the actual indoor temperature and the actual indoor humidity do not meet the comfort requirements, the mechanical ventilation structure 2 is turned on and its opening is adjusted until the comfort requirements are met, specifically including:

[0069] When the actual indoor temperature and the actual indoor humidity do not meet the comfort requirements, open the mechanical ventilation structure 2 and / or the mechanical ventilation and fire smoke exhaust structure 3, and adjust the opening of the mechanical ventilation structure 2 and / or the mechanical ventilation and fire smoke exhaust structure 3 until the comfort requirements are met.

[0070] In this embodiment, the temperature and humidity in the gymnasium are regulated by adjusting the mechanical ventilation structure 2 and the mechanical ventilation and fire smoke exhaust structure 3 to be opened separately or simultaneously. The regulation speed is faster and more flexible, which is conducive to energy saving and emission reduction.

[0071] Furthermore, satisfying the comfort requirement specifically includes:

[0072] The outdoor actual temperature and the outdoor actual humidity are respectively equal to the preset temperature and the preset humidity, or the indoor actual temperature and the indoor actual humidity are respectively equal to the preset temperature and the preset humidity.

[0073] It is worth noting that, according to the specifications of parameters such as the temperature of the gymnasium, the preset temperature is 18°C ​​to 22°C, the preset humidity is 40% to 60%, and the preset wind speed is <0.5m / s, which not only meets the specifications but also helps to save energy.
