Extended data:

Working principle:

The transmission mode of fresh air is replacement, not the internal circulation principle of air conditioning gas and the bad practice of mixing old and new gases. Outdoor fresh air will be automatically sucked into the room through negative pressure, and it will be automatically dedusted and filtered when it enters the room through the fresh air outlet installed in the bedroom, living room or living room window. At the same time, the corresponding indoor pipes are connected to the exhaust ports of several functional rooms, and the circulating system will take away the indoor exhaust gas and concentrate it on the exhaust port to "exhale", but the exhausted exhaust gas will not be recovered, and the new and old air forms circulate well.
