The inner air inlet is upwardly connected to the air mixing chamber. The mixed air outlet is provided at the top of the casing and connected to the air mixing chamber. The inner air inlet is provided with an oxygen content control for the fan and the air door The sensor is equipped with a deflector on the upper side of the inner air inlet. The deflector extends from the air inlet to the mixed air outlet.
本发明工作时，可将其设置在室内，通过氧含量传感器探测室内空气中的氧气含量，当氧气含量低于设定阈值时，风机启动，风门开启，从室外向室内吹风，通过风门开度的调节，可以控制向室内供风量，室内相对污浊的空气可从门窗的缝隙中排出，从而保持室内空气清新怡人。缓风室具有缓流降噪的作用，可减小风机供风时的风噪声，气嘴的作用有两个， 其一，可进一步降低风噪声，其二，可形成向上引射的射流，引导内进风口来的气流从混合风出口离开；混风室的作用在于保证室外来的新风和室内空气进行良好混合，避免室内温度不均匀。与现有技术相比，该装置具有混风均匀，可实现换气量自动调节，换气时噪音小，静音效果好的优点。When the present invention works, it can be installed indoors, and the oxygen content sensor can detect the oxygen content in the indoor air. When the oxygen content is lower than the set threshold, the fan starts, the damper opens, and the air blows from the outdoor to the interior, through the damper opening The adjustment can control the amount of air supply to the room. The relatively dirty air in the room can be discharged from the gap between the doors and windows, thereby keeping the indoor air fresh and pleasant. The air damping chamber has the effect of slow flow and noise reduction, which can reduce the wind noise when the fan is supplying the air. The function of the air nozzle has two.

The heat exchanger can be an electric heater or an air conditioner evaporator. The heat exchanger can exchange heat, and can warm the indoor air when the temperature is low. When the temperature is high, the indoor air can be cooled. When the temperature is appropriate, the heat exchanger may not work. It is worth mentioning that when the air needs to be heated, the indoor air enters from the inner air inlet, and is heated and leaves the mixed air outlet. The heated density of the air is reduced, forming a motive force for upward movement, which can form a suction at the air nozzle. In this case, the fan can be turned on without turning on the fan, and the ventilation can be completed only by controlling the opening of the damper. Therefore, under this working condition, it has the effect of absolute silence.
