HVAC systems as an important means of combating viruses

Ukraine is on the verge of an epidemic of coronavirus, which has already spread throughout Europe and has proved to be the most difficult challenge for all of humanity. To prevent the development of the most pessimistic scenario, one should turn to the facts and use all possible means to protect people.

So, any virus, including COVID-19, lives only in the human body, in the environment it weakens and dies. In the fresh air, he lives for several hours, in enclosed spaces, depending on the surface, up to 3-4 days. The main method of transmission of coronavirus from person to person is the airborne droplet path. Especially a lot of bacteria spread from sneezing and coughing. In buildings with poor ventilation, pathogenic particles can be in the air for several hours, which is enough to infect more than one person.

There are many scientific articles on the connection between the spread of infections and ventilation. It is noteworthy that one of the first evidence was obtained in the 1970s, when a passenger with the flu appeared on board the aircraft, by coincidence, the ventilation system was malfunctioning, and one flight was enough for 75% of passengers to become infected.

This suggests that in the fight against infectious diseases, a properly ventilated and air-conditioned room significantly reduces the number of pathogenic microbes, improves air quality and creates a healthy microclimate. Therefore, under the current conditions, care should be taken to ensure the smooth operation of this equipment, conduct unscheduled maintenance, change filters and reconfigure the system for better ventilation.

SHEN has many years of experience with all possible ventilation and air conditioning systems. Now we are doing everything possible to reduce to zero the threat of infection inside the serviced buildings. We strongly recommend that you check this critical equipment again to reduce the risks of spreading the infection and to protect staff and guests.
