[0048] 1. In the process of installing ventilation equipment, especially in high-altitude operations, the installation method from indoor to outdoor without auxiliary tools is realized, which promotes high installation efficiency and reduces installation costs; the waterproof design of silicone sleeve improves the seal between the casing and the wall hole In order to achieve the effect of waterproofing; 2. During the working process of the ventilation equipment, when the airflow passes through the heat exchange core of the above-mentioned structure, it can increase the diversity of airflow channels and increase the contact area between the airflow and the heat exchange material, and finally increase Heat exchange efficiency; 3. The shutters will be closed in non-working state, blocking foreign matter from entering the room from the outside; the difference between the positive and reverse air volume values ​​in normal use is small, which ensures the heat exchange application process The heat exchange efficiency is at a relatively high level; the differentiation of functional modes is achieved through LED color rendering, which greatly improves the customer experience.
