Indoor air cleaning system

An indoor air cleaning system, comprising:

• a plurality of gas detection modules for detecting air pollution and outputting air pollution data, which are calculated and processed to output a plurality of regulation signals;
• a plurality of air cleaning devices disposed in an indoor field, and each comprising a fan, a filtering element and a driving control component, wherein the plurality of gas detection modules are disposed within the plurality of air cleaning devices, and electrically connected to the fan and the driving control component, wherein the driving control component regulates an activation operation, airflow volume and noise of the fan according to the plurality of regulation signals received, and the fan is controlled to start guiding the air pollution passing through the filtering element for filtration;
• and
• at least one central control and regulation device connected to the plurality of gas detection modules, wherein the at least one central control and regulation device is connected under handshake communication protocol of wired communication or wireless communication to provide control instruction signals to the plurality of gas detection modules for regulating operations of the fans of the plurality of air cleaning devices, and the at least one central control and regulation device receives the air pollution data detected by the plurality of gas detection modules for displaying in real time;
• wherein a gas state of the air pollution in the indoor reaches the air pollution data, which is targeted by the plurality of the gas detection modules based on a cumulative number of PM2.5 inhaled suspended particles detected in 24 hours and a required indoor field space for one of the plurality of air cleaning devices, so as to meet a clean room requirement of ZAPClean Room 1˜9.
