Air treatment equipment and energy-saving control method thereof, electronic equipment and storage medium

The invention discloses air treatment equipment and an energy-saving control method thereof, electronic equipment and a storage medium. The air treatment equipment comprises a fresh air duct and an exhaust air duct, a fresh air valve is arranged at an inlet of the fresh air duct, an exhaust air valve is arranged at an outlet of the exhaust air duct, and an air return valve is further arranged between the fresh air duct and the exhaust air duct. And when it is determined that the air treatment equipment needs to start the purification function according to the indoor air quality information, the fresh air valve and the exhaust air valve are controlled to be closed, and the return air valve is controlled to be opened, so that fresh air flowing through the fresh air duct is purified through a purification device arranged in the fresh air duct. Therefore, the air quality can be optimized, meanwhile, heat and cold management is carried out in an internal circulation mode, energy recovery is achieved, and the purpose of saving energy consumption is achieved.
