Fresh air system is widely used in many scenarios, mainly including the following:
Heat exchange mode: Applicable to air conditioners in summer or floor heating in winter. In summer or winter, when the temperature difference between indoor and outdoor is large, turn on the heat exchange mode. After heat exchange, the temperature of outdoor air is close to the indoor temperature, reducing the operating load of air conditioners or floor heating, and achieving energy saving effect.
Bypass mode: Applicable to spring and autumn. The climate is suitable in spring and autumn, but there are more catkins, pollen and dust in the air, and people with sensitive respiratory tract dare not open the window. The bypass mode skips the heat exchange step and introduces the air into the room after purification by the filter to ensure more peace of mind.
Internal circulation mode: Applicable to bad weather, such as sandstorms. In the internal circulation mode, only the indoor air is circulated and filtered to protect the life of the filter, similar to the "whole house air purifier", but fresh air cannot be sent to the room in this mode, and it is not recommended to turn it on for a long time.
Anti-pollution mode: Applicable when the outdoor air is heavily polluted, such as haze days. After turning on the anti-pollution mode, the air supply volume is greater than the exhaust volume, and the indoor air pressure is higher than the outdoor pressure, which effectively prevents outdoor air from entering the room through the window gaps, reduces the frequency of cleaning, and allows you to breathe fresh air anytime, anywhere.
Deodorization mode: Suitable for homes with pets. After turning on the deodorization mode, the exhaust volume is greater than the air supply volume, effectively eliminating indoor odors and keeping the air fresh.
Automatic mode: Suitable for novice users. In automatic mode, the fresh air system will automatically switch between "heat exchange", "bypass" and "internal circulation" according to sensor data, which is suitable for users who can't remember the applicable scenarios of each mode.
