Description
Technical Field
The invention relates to the field of respiratory tract virus propagation blocking of new coronary pneumonia, in particular to an indoor fresh air system beneficial to prevention and control of new coronary pneumonia.
Background
New coronavirus has been abused worldwide and the world health organization has called new crown pneumonia epidemics as global pandemics. The prevention and control difficulty of the novel coronavirus is increased due to the existence of asymptomatic infectors.
When the epidemic situation is relieved, the reworking and reproduction will become the main melody, but the risk of the epidemic situation exists in the reworking and reproduction in a closed building. In cities, most classrooms of schools are only provided with a window on one wall, and for safety, the window of the classroom is higher and smaller, the ventilation condition is not good enough, and certain risk of collective infection is caused.
In modern buildings, the traditional air conditioning system has no epidemic prevention function for preventing the spread of respiratory infectious diseases, and particularly, a central air conditioner adopting a whole-area air return system is easy to cause cross infection. Even if a VRF system or VWV independent zone return air system is used in a building air conditioner, turbulent air can form between the outlet and the return air inlet, which can cause the virus-laden aerosol to fly and diffuse and partially circulate in the room. Therefore, experts recommend that central air conditioners not be opened during epidemic situations.
Asymptomatic infected persons have proven to be contagious. In order to avoid infection of asymptomatic infected persons in a closed office building, the only method is to open windows for ventilation and wear a mask.
However, many rooms do not have windowing ventilation conditions, and wearing the mask for a long time causes slight oxygen deficiency, reduces the adaptability of the body to the nature, destroys the blood circulation of nasal mucosa, and brings uncomfortable feeling to the mouth, the nose and the ears, and particularly in summer, the temperature rises, and the wearing of the mask is more uncomfortable.
People hope to upgrade and reform the existing fresh air system matched with the air conditioner, and the function of preventing the respiratory virus from spreading is added.
