The invention discloses an air management intelligent fresh air system which comprises a fresh air host, an air management device, a first air pipe, integrated sensor nodes and a central master controller. The fresh air host is connected with the air management device through the first air pipe. The central master controller is in wireless connection with the integrated sensor nodes arranged in rooms. According to the air management intelligent fresh air system, the air management device is introduced, a filter screen integration module is additionally arranged, and therefore the problem that the area of a filter screen in a current fresh air ventilator is too small can be solved, the filter efficiency can be effectively improved, and the service life of a filter screen can be effectively prolonged; and the original manner of manually adjusting the size of an air outlet is converted into automatic adjustment, the air volume of each room is precisely controlled, and the dynamic adjusting manner of distributing fresh air according to needs is achieved. The system adopts the wireless communication technology, the integrated sensor technology, the internet technology, the mechanical automation technology and other high technologies, real-time monitoring, dynamic adjusting and intelligent control of the indoor air environment can be achieved, the actual needs of the family life environment can be met, and practical significance is achieved.
