Description

Technical Field

[0001] The invention relates to the technical field of building ventilation and air exchange, in particular to a ventilation and air exchange device for green buildings. Background Art

[0002] With the advancement of global industrialization and urbanization, the concept of green building has received increasing attention. Green building emphasizes maximizing resource conservation, protecting the environment and reducing pollution throughout the entire life cycle of the building, providing people with healthy, applicable and efficient use space, and coexisting harmoniously with nature. As an important part of green building, the design and application of ventilation and air exchange devices are of great significance to improving the quality of the internal environment of the building and achieving energy conservation and emission reduction. The main goal of ventilation and air exchange devices for green buildings is to achieve effective circulation and renewal of air inside the building to maintain good indoor air quality. The realization of this goal depends on the comprehensive use of multiple technical means. A common ventilation method It is natural ventilation, which uses natural conditions such as indoor and outdoor temperature difference and wind pressure to achieve natural air flow through the openings of the building (such as windows, doors, and vents). Natural ventilation can not only reduce the energy consumption of the building, but also provide fresh natural air and improve people's living environment. However, in some cases, natural ventilation may not meet the ventilation needs of the building. It is often difficult to achieve effective ventilation by relying solely on natural wind pressure and heat pressure. In addition, in cities with serious air pollution and noise pollution, direct natural ventilation may also bring outdoor dirty air and noise into the room, causing adverse effects on human health. Therefore, in these cases, mechanical ventilation or mixed ventilation is needed: An energy-saving and environmentally friendly ventilation device disclosed in announcement number CN113959034A includes a shell, a fixing rod is bolted to the inner wall of the shell, a first fixing block is bolted to the other end of the fixing rod, a motor is embedded in the surface of the first fixing block, a tightening mechanism is provided at the output end of the motor, a fan blade is slidably sleeved at the output end of the motor, and the fan blade is located on the left side of the tightening mechanism, a second fixing block is slidably sleeved at the output end of the motor, and the second fixing block is located on the left side of the fan blade; the present invention can achieve the purpose of facilitating the cleaning of the fan blade by pulling the pull rod to make the connecting rod drive the clamping joint to move and disengage the clamping joint from the second fixing block, thereby reducing labor intensity, improving cleaning efficiency, and avoiding the need to disassemble the entire device for cleaning, which is very troublesome, labor-intensive, and inefficient; When the above-mentioned prior art is in use, the fan blades rotate to transport the outside air into the shell through the fan blades to purify and inject it into the room. However, in this process, the size of the shell opening for air inlet is not convenient to adjust. Therefore, under different environments (such as changes in wind speed, changes in indoor and outdoor temperature differences, etc.), the ventilation effect may not reach the optimal state. For example, when the outdoor wind speed is high, if the air inlet cannot be reduced to control the amount of air entering the room, the indoor wind speed may be too high, affecting comfort and safety. If the air inlet cannot be adjusted as needed, it may be necessary to consume more energy to maintain ventilation when it is not necessary, resulting in a waste of resources. Therefore, corresponding improvements are needed. An automatic ventilation device capable of preventing strong light is disclosed in the announcement number CN112128909A, comprising a control panel, a sensor group, a ventilation device and a strong light device, wherein the ventilation device is arranged above the window; the strong light device is arranged on the inner side of the classroom window, and the strong light device comprises a plurality of round rods, a plurality of blinds, a plurality of clamps, two transmission rods and two push rod motors, and when the push rods move up and down along the sliding grooves, the blinds can move in a partial circle around the round rods, thereby realizing the angle adjustment of the blinds, thereby playing a role in preventing strong light; by separating the automatic ventilation device and the strong light device, and using the sensor group to detect the surrounding environment to guide the controller to control the ventilation device and the strong light device, the problem that there is no automatic strong light prevention and ventilation device in the smart classroom at the same time is solved; When in use, the above-mentioned prior art utilizes the air intake fan to perform ventilation, but in this process, there is a lack of a design for stirring and breaking up the airflow. The airflow without a stirring and breaking up design may form vortices or accumulate in certain areas indoors due to the position of the air intake fan and the wind intensity, resulting in uneven airflow distribution, which may affect the ventilation effect and make the air in certain areas unable to be effectively updated, thereby affecting the indoor air quality and reducing the ventilation efficiency. This means that even if the air intake fan is working, the indoor air renewal speed may not be as expected. Therefore, corresponding improvements are needed. Summary of the invention
