The effect of aerosol coagulation under complex electric fields

A mathematical and physical model of the aerosol coagulation under the joint action of high voltage and high frequency complex electric fields is developed and solution of the half time T_H is obtained. At the same time, a set of experimental device is built to verify the theoretical model. The results show that the half time T_H will drop while the initial concentration of the aerosol particles reduce in air conditioning room and the air change rate required for concentration halved will reduce with increasing initial concentration. Compared with the theoretical filter model, the half time T_H is reduced nearly half when they work together. The time of indoor air purification of air purification of air conditioning is greatly shortened.
