Indoor ventilation system beneficial to prevention and control of novel coronavirus pneumonia

Abstract

The invention discloses an indoor ventilation system beneficial to prevention and control of novel coronavirus pneumonia. The indoor ventilation system comprises a fresh air collection and dust removal module, a foul air exhaust module, an energy recovery module, an indoor foul air recovery module, a fresh air distribution module, a close-range air supply device, an indoor foul air recovery moduleand a foul air exhaust module. The indoor ventilation system is characterized in that the fresh air collection and dust removal module is composed of an exhaust fan and an air filter and is responsible for sucking outdoor fresh air inwards and conveying the outdoor fresh air into the energy recovery module after filtration and purification, the energy recovery module is composed of a heat energyrecovering device and a heat energy exchanger and is responsible for recovering energy from indoor foul air and conducting the energy to the fresh air, so that the temperature of the fresh air is close to the indoor temperature, and a fresh air heating and humidifying module is composed of a ceramic fever piece and a circulating water wet film humidifier and is responsible for adjusting the temperature and humidity of the fresh air in cold days so as to improve the breathing comfort. The indoor ventilation system is particularly suitable for being installed in indoor office and study places with dense personnel, and can effectively prevent aggregation respiratory tract infection.

Description

technical field [0001] The present invention relates to the field of blocking the transmission of COVID-19 respiratory virus, in particular to an indoor fresh air system that is helpful for the prevention and control of COVID-19. Background technique [0002] The new crown virus has ravaged the world, and the World Health Organization has called the new crown pneumonia epidemic a global pandemic. Due to the existence of asymptomatic infections, the prevention and control of the new coronavirus is more difficult. [0003] When the epidemic eases, the resumption of work, production and school will become the main theme, but resuming work and production in relatively closed buildings has the risk of epidemic situation. In cities, most school classrooms have windows on only one wall. For the sake of safety, classroom windows are taller and smaller, and the ventilation is not good, which poses a certain risk of cluster infection. [0004] When working or living in a modern buil...

Problems solved by technology

[0006] However, many rooms do not have the conditions to open windows for ventilation, and wearing a mask for a long time will cause slight hypoxia, reduce the body's adaptability to nature, damage the blood circulation of the nasal mucosa, and cause discomfort in the mouth, nose, and ears. , especially in summer, when the temperature rises, it will be more uncomfortable to wear a mask
