Abstract:
An air purification system and a control method thereof. The system comprises: a main machine, a secondary machine, a control module (8), and a main machine purification module (7). A main machine fan (6) comprised in the main machine drives air to enter from a main machine air inlet (5) and to be output from a main machine air outlet (9). The main machine purification module (7) purifies the input air. A secondary machine fan (1) comprised in the secondary machine drives air to enter from a secondary machine air inlet (2) and to be output from a secondary machine air outlet (4). The control module (8) is used to control the rotation of one or more of the main machine fans (6) and one or more of the secondary machine fans (1), and to control operation of one or more of the main machine purification modules (7). In the air purification system, the secondary machine also circulates air when the main machine is in purification mode, thereby improving airflow as well as the effectiveness and efficiency of air purification.
