Is it necessary to install fresh air system?

It is necessary to install the fresh air system.

the fresh air system can not only purify the indoor air, but also control the humidity of the air entering the room within a comfortable range. For example, in summer, the indoor temperature is low, so the outdoor air not only has high temperature and humidity when it enters the room, but also contains more pollutants. The fresh air system dries the fresh air while purifying, so that the indoor humidity is well controlled.

the fresh air system has the function of filtering the pollutants in the indoor and outdoor air. The fresh air system introduces the outdoor air into the room after filtering, and at the same time discharges the dirty indoor air. The whole process realizes air replacement, increases the concentration of indoor oxygen, and makes the indoor air fresh and clean.

The fresh air system is equipped with sensors, which can monitor indoor temperature, humidity, PM2.5 concentration and carbon dioxide concentration in real time, analyze and process the data in real time, and realize remote control.

the air supply function of the air conditioner will not introduce fresh air. Simply put, it is a fan, which only regulates indoor air circulation; The air purifier will not introduce fresh air. Mainly to purify the dust and bacteria in the indoor air, there is no way to solve the gas pollution, such as formaldehyde and carbon monoxide.

The fresh air system can realize indoor and outdoor air exchange, introduce fresh outdoor air, and discharge turbid air such as formaldehyde and carbon dioxide. But it can't achieve the purpose of indoor cooling in summer, that is to say, even if your home is equipped with fresh air system, you still need to install air conditioning.
