Does Haier air conditioner have a special ventilation module device?

Yes, for example, Haier KFRd-35GW/A(QXF) adopts the patented two-way ventilation technology. The double fresh air unit has two fans. One fan sends outdoor fresh air indoors, and the other fan discharges indoor dirty air outdoors. In the process of conveying fresh air and exhausting dirty air, the two kinds of air completely exchange heat and humidity through a total heat exchanger, so as to recover heat and humidity, get fresh air and exhaust it. During the whole exchange process, the two gases will not mix.
