Residential energy exchange ventilator (full heat exchange fresh air system) improves indoor air quality and achieves efficient energy utilization through two-way airflow circulation and heat 

exchange technology. 

Its core functions can be summarized into the following five aspects:

1. Basic functions: ventilation and air purification

‌Continuous ventilation ‌

Indoor and outdoor air circulation can be achieved without opening windows, solving the problem of poor ventilation, especially suitable for modern houses with strong airtightness ‌

‌

Pollutant filtration ‌

Multi-layer filter can intercept outdoor pollutants such as PM2.5, pollen, bacteria, etc., while emitting indoor harmful gases such as formaldehyde and carbon dioxide to reduce the concentration of allergens ‌

2. Energy management: energy saving and efficiency improvement ‌ ‌Cold and heat recovery ‌

Recover 60%-70% of the heat/cold in the exhausted air through the full heat exchange core, preheat or precool the introduced fresh air, and reduce air conditioning energy consumption ‌ ‌

‌Temperature and humidity regulation ‌

Transmit temperature (sensible heat) and humidity (latent heat) at the same time, maintain indoor temperature and humidity stability, and avoid energy loss caused by traditional ventilation ‌

3. Health protection

‌Pathogen suppression‌

Some models are equipped with negative ion sterilization function, which can remove viruses, bacteria and mites, and reduce the risk of respiratory disease transmission‌

‌

Protection of special groups‌

Provide clean air for sensitive groups such as pregnant women, children, and the elderly, and alleviate environmental threats such as decoration pollution and haze‌

4. Optimization of living experience

‌Noise reduction and dust prevention‌

Replace window ventilation, block outdoor noise and dust pollution, and create a quiet and clean indoor environment‌

‌Increase oxygen content‌

Continuously input oxygen-rich fresh air, simulate the effect of forest oxygen bar, and improve human comfort‌

5. Application scenario adaptation

‌Extreme climate zone‌: Reduce energy loss caused by ventilation in cold/hot areas‌

‌Low-rise/street-facing residences‌: Balance ventilation needs with noise/dust problems‌

‌Newly renovated houses‌: Accelerate the emission of harmful gases such as formaldehyde‌
