Technical Field

[0002] Variable frequency ventilation technology is an advanced ventilation control technology. It changes the motor speed by adjusting the power supply frequency of the motor, thereby achieving precise control of parameters such as the air volume and air pressure of the ventilation equipment. Existing ventilation equipment only transports outdoor air into the room. When the outdoor air quality is poor, it will pollute the indoor air and cannot significantly improve the indoor air quality, thus affecting the ventilation effect of the equipment on the air.

[0003] The prior art CN215809083U discloses an adjustable variable frequency ventilation device for a laboratory, comprising a variable frequency fan, a ventilation pipe, a purification tank, a purification layer and a connecting hose. The outer wall of the purification layer is fixedly connected to the inner wall of the purification tank. When the variable frequency fan is started, the indoor air and the outdoor air are simultaneously sucked into the purification tank through the ventilation pipe. The purification layer purifies the air entering the purification tank. The purified air enters the connecting hose and is sent to the room through the variable frequency fan. This allows the device to ventilate the laboratory while purifying the ventilated air, thereby improving the ventilation effect of the device on the air.
