Description

technical field [0001] The invention relates to the field of air quality adjustment, in particular to a fresh fan and a control method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for indoor air quality. A fresh air blower that can efficiently clean the air, have a high energy efficiency ratio, and is intelligent and easy to use is what consumers need. [0003] The fresh air fan is an effective air purification equipment, which can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the outdoor fresh air is sterilized, disinfected, filtered and other measures, and then input into the Indoors, let the room be fresh and clean air all the time. The fresh air blower can achieve convection of indoor air through independent air supply and induction, so as to maximize indoor air replacement. Its built-in purification system ensures that the air ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, functions such as opening and closing of the fresh air fan are limited to remote control or button control on the fresh air fan. When the indoor control quality deteriorates or improves, it cannot be automatically and intelligently turned on and off, and the degree of automation is low. Unable to learn in real time and automatically improve indoor air quality
