With the improvement of the quality of modern life, the fresh air system has gradually become a necessary equipment for many homes and offices. The main function of the fresh air system is to adjust the indoor air quality, but many people have questions about whether the Windows need to be closed when using the fresh air system. This article will discuss this issue, for you to analyze the operating principle of the fresh air system and its association with the window opening.

First, the basic principle of fresh air system

Fresh air system is a modern air conditioning equipment, which provides fresh and clean air for the room through a series of filtration, ventilation and other processes. The fresh air system is mainly composed of air supply outlet, exhaust outlet and fan, which inhales the outdoor fresh air into the room through the fan and exhausts the indoor dirty air to maintain the freshness of the indoor air.
Second, the relationship between opening the fresh air system and opening the window
Whether you need to close the window when opening the fresh air system depends on your specific needs and outdoor environment.
1. When the outdoor air quality is good
When the outdoor air quality is good, opening the fresh air system can help you bring the fresh air outside into the room, while discharging the dirty air inside. In this case, if there is a large noise or other disturbing factors outside, you can consider closing the Windows to better utilize the function of the fresh air system.
2. When outdoor air quality is poor
If the outdoor air quality is poor, such as when the haze is serious or the concentration of other pollutants is high, it is particularly important to close the Windows while opening the fresh air system. This can prevent outdoor pollutants from entering the indoor, while providing relatively clean air for your living or working environment through the filtration function of the fresh air system.
3. Consideration in special circumstances
In some special cases, such as the need for rapid ventilation or indoor temperature adjustment, you can choose to open or close the window according to the actual situation. In addition, if there is a large temperature difference between your home or office space and the external environment, it is recommended that you adjust the wind direction and air volume when opening the fresh air system to achieve a better ventilation effect.

Third, how to use the fresh air system correctly

In order to ensure the normal operation and better use of the fresh air system, you need to pay attention to the following points:
1. Regular maintenance and maintenance: regularly check the filter, pipeline and other components of the fresh air system to ensure its normal operation.
2. Set parameters reasonably: Adjust the operating parameters of the fresh air system reasonably according to the changes in the indoor and outdoor environment to achieve the best air exchange effect.
3. Pay attention to the outdoor environment: When opening the fresh air system, pay attention to the outdoor environment. In case of bad weather or poor air quality, adjust the system operation mode or close the window in time.
4. With other measures: When necessary, you can combine other air purification equipment or measures, such as air purifiers, green plants, etc., to jointly improve indoor air quality.
Iv. Summary

In most cases, in order to make better use of the function of the fresh air system and keep the indoor air clean, it is recommended to properly close the Windows when using the fresh air system. However, it is also necessary to flexibly adjust according to the actual situation to achieve the best ventilation effect. At the same time, pay attention to the daily maintenance and maintenance of the fresh air system to ensure its normal operation and extend its service life.
