Deux types de modèles: type de récupération de chaleur totale (échangeur de chaleur total) et type de récupération de chaleur sensible (échangeur de chaleur sensible)

Adopting a bidirectional ventilation method, utilizing mechanical air supply and induced draft to force the formation of a new airflow field within the system. At the same time as discharging polluted indoor air outside, introduce fresh outdoor air into the room. Moreover, in order to avoid significant fluctuations in indoor temperature caused by ventilation, an air heat exchanger is installed inside the fresh air ventilator to exchange temperature between the old and new air, achieving the effect of both ventilation and maintaining basic stability of indoor temperature.

Avantages techniques:

The product is equipped with different filtering materials, which can effectively filter dust particles, fibers, and other impurities in the air, preventing dust from outdoor air from entering the room. Some models can be customized with photocatalytic disinfection technology. The product achieves heat exchange between fresh air and exhaust air through a heat exchanger, which can reduce the temperature of fresh air in summer and increase it in winter, greatly saving energy consumption in fresh air pretreatment. Equipped with bidirectional indoor and outdoor ventilation, equal displacement of intake and exhaust air, ensuring a continuous supply of fresh air, controlling room temperature changes, and maintaining the freshness and comfort of indoor air
