Abstract

The invention provides a fresh air fan and a control method for the air feed volume and the air exhaust volume of the fresh air fan. The control method comprises the steps that the air pollution index is obtained; the pollutant accumulation value is calculated; the current actual air volume of an air feeder is obtained from a parameter list according to the pollutant accumulation value; the air feed volume is compared with the air exhaust volume, the air volume of the air feeder and the air volume of an exhaust fan are adjusted, and accordingly the air feed volume is larger than the air exhaust volume. The invention further discloses the fresh air fan adopting the control method for the air feed volume and the air exhaust volume. By the adoption of the embodiment, it can be guaranteed that the fresh air fan continuously works in a micro-positive pressure state.

Description

technical field [0001] The invention relates to the field of fresh air fan equipment, in particular to a fresh air fan and a method for controlling the air supply volume and exhaust air volume thereof. Background technique [0002] The fresh air fan is an effective air purification device that can circulate indoor and outdoor air. On the one hand, it discharges the indoor dirty air to the outside, and on the other hand, the outdoor fresh air is sterilized, disinfected, filtered and other measures, and then re-entered. When entering the room, let the room have fresh and clean air all the time. The fresh air fan uses the patented fresh air convection technology to achieve convection of the indoor air through independent air supply and induction, thereby maximizing the indoor air replacement. The new The built-in multifunctional purification system of the fan ensures that the air entering the room is clean and healthy. [0003] The fresh air fans provided by the prior art are ...
