When a closed environment is exposed to intense air pollution and unhealthy weather conditions, the systems that effectively provide clean air to this environment are called ventilation systems. It would be correct to say that there are many types of ventilation systems and different principles of operation. In general, the usage environment and the purpose of use in ventilation systems are known as the essential factor in determining the system.

Since the dirty air inside harms not only human health but also many factors, it is possible to say that ventilation systems should be used in many environments. It would be highly wrong to think that ventilation systems pollute the environment or the atmosphere because they release polluted air into the outside environment. Studies are carried out in the field of ventilation systems and ventilation systems technology that prevent this situation. On the other hand, ventilation systems are preferred according to the use area because the capacity of each use area is different, so the amount of need can vary
