Continuous ventilation and oxygen supply
No need to open windows to introduce outdoor fresh air and exhaust indoor dirty air, avoiding hypoxia caused by excessive carbon dioxide concentration, especially suitable for haze days, extreme weather or closed scenes.
Reducing energy loss through heat exchange technology (such as heat recovery module), recovering cold/heat of exhaust air, and reducing air conditioning energy consumption.
High-efficiency air purification
Multi-layer filter (primary, medium and high efficiency, high efficiency) can filter PM2.5, pollen, bacteria and other particulate matter, with an interception rate of up to 99%.
Remove decoration pollutants such as formaldehyde and benzene and TVOC (volatile organic compounds), reducing the risk of respiratory diseases.
Humidity and odor control
The dehumidification module can absorb indoor moisture, prevent mold growth, and extend the life of furniture.
Replace air in real time, eliminate oil smoke, pet odor and floor drain odor, and maintain a fresh environment.
Safety and convenience
Avoids safety hazards caused by opening windows (such as theft, wind and rain), suitable for long-term unoccupied residences.
Low noise design (some models operate at a volume as low as 20 decibels) to reduce interference with life or sleep.
Energy saving and long-term benefits
Reduce energy consumption by intelligently adjusting the air supply volume, and save air conditioning electricity bills for long-term use.
Reduce indoor dust accumulation, reduce cleaning frequency, and extend the service life of home appliances.
Application Scenarios Of Full Fresh Air System
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.
Types Of Full Fresh Air System
Positive pressure fresh air system: The fan introduces outdoor fresh air into the room, making the indoor air pressure higher than the outdoor pressure, effectively preventing outdoor dirty air from entering the room. Suitable for places with high requirements for indoor air quality but low requirements for energy conservation, such as small offices, bedrooms, etc.
Negative pressure fresh air system: The fan discharges indoor dirty air to the outside, making the indoor air pressure lower than the outdoor pressure, and outdoor fresh air enters the room through the gaps of doors and windows. Suitable for places with high requirements for indoor air discharge but low requirements for indoor air quality, such as kitchens, bathrooms, etc.
Two-way flow fresh air system: It consists of a supply fan and an exhaust fan, which can not only introduce outdoor fresh air, but also exhaust indoor dirty air. Suitable for places where air needs to be introduced and exhausted at the same time.
Full heat exchange fresh air system: It has two built-in fans and heat exchange cores, with energy recovery devices, usually concealed in the ceiling, suitable for installation before decoration.
One-way fresh air system: There is only one fan, and there is only one direction of airflow when working.
Wall-mounted fresh air system: It is designed in a cylindrical shape, with all components integrated in a cylinder, and pre-opened on the wall for installation, suitable for installation before decoration.
Vertical cabinet fresh air system: Beautiful appearance, deep purification, intelligent control, simple installation, and convenient maintenance, suitable for family living rooms or small commercial places.
Window ventilator: There are horizontal and vertical types, with a filter device inside to filter the air.
Working Principle Of Fresh Air System
The fresh air system forms indoor and outdoor air circulation through mechanical forced ventilation, uses air supply and exhaust systems to build a "fresh air flow field", and combines filtering, temperature control and other functions to achieve air replacement.
Forced ventilation forms a flow field
The system forces purified outdoor air into one side of the closed room through a high-pressure fan, and exhausts dirty air on the other side through exhaust equipment, forming a directional "fresh air flow field".
Airflow organization methods include
• Positive pressure air supply: Directly supply air to the room, but the convection is weak.
• Negative pressure ventilation: The exhaust fan sucks air to form a low-pressure area, which promotes the natural inflow of outdoor air and makes the airflow more stable.
Air treatment process
• Triple purification: Outdoor air passes through the primary filter, IFD micro-electrostatic filter, and HEPA high-efficiency filter to remove pollutants such as particulate matter and bacteria.
• Additional functions: Some systems have preheating (in winter), oxygenation, sterilization and other functions to improve air supply quality.
Heat recovery and temperature control (advanced system)
The two-way heat recovery system recovers heat/cold from the exhaust air through a full heat exchanger to reduce energy loss.
The temperature control system maintains a stable supply air temperature through the linkage of sensors and electric regulating valves (such as PI control in the fresh air unit).
