The epidemic has done us too much harm, and we hope everyone can protect themselves and their families.
Return to work after the festival. In order to protect yourself, protect the people around you, and be familiar with the general knowledge of starting and returning to work, the most comprehensive necessary prevention and control items are: protective mask, 84 disinfectant / 75% alcohol solution, disinfectant hand sanitizer, goggles, hands sanitizer, electronic thermometer, protective clothing, and bucket return.
The entrance is ready for disinfection and temperature measurement. None of them will be let go
All of the above are the basis of protection during the epidemic. With the rapid increase of modern respiratory diseases, some decoration materials with long-term volatile nature are used, which brings harm to our work and life. Indoor air quality is more and more not optimistic, the application of fresh air system in our work and life is more urgent, our work and life also need a fresh and healthy air.
Indoor, fresh air system plays an important role in air circulation and air purification, which is very helpful to our health.
Question 1: what is the fresh air system?
The fresh air system is to deliver the outdoor fresh air to the room through multiple filtration without opening windows through air supply and exhaust, and to discharge the indoor air to the outside at the same time.
Question 2: can the fresh air system, air conditioner and air purifier replace each other?
NO!
Fresh air system: indoor and outdoor air exchange, introduction of outdoor fresh air, discharge of indoor formaldehyde, carbon dioxide, bacteria and viruses and other turbid air, reduce harmful substances in indoor air, and maintain the balance of indoor oxygen and carbon dioxide concentration.
Air supply of air conditioning: air conditioning filtration is relatively simple, only filtering large particles to prevent pipe blockage, and heating or cooling the air through the temperature regulating system, which does not meet the requirements of fresh air.
Air purifier: it can clean the dust and bacteria in the indoor air, and the air circulates internally, but the scope of action is limited. Long time use can not effectively reduce the harmful substances in the indoor air, but the indoor oxygen and carbon dioxide concentration ratio is out of adjustment due to the activities of personnel.
Ventilation is the core function of the fresh air system. Reasonable indoor ventilation mainly aims at two key links: distribution according to demand and orderly flow. On demand distribution is to send fresh air to the most needed position of human body, that is, the place where indoor people often move, and also the place where fresh air is most needed. The air inlet should be arranged in these areas as far as possible.
At the same time, the exhaust outlet should be arranged in the dead corner of the room where the dirty air accumulates and is difficult to be discharged, so as to eliminate the hazards completely. Orderly flow requires that the fresh air entering the room should have a reasonable (most needed by human body), smooth (no block or less block), clear and orderly flow direction. The purpose of doing so is to facilitate thorough ventilation on the one hand, and on the other hand, it also reduces the work load of the fresh air host, energy conservation and emission reduction. The quality of equipment hardware is the first life of the fresh air system, while the design and construction are its second life. "Design" determines the actual air exchange capacity of the fresh air system to a certain extent.
The fresh air system not only replenishes oxygen, but also removes pollution. It has built a natural protective barrier for our work and life, so that our body can be effectively protected!
