Abstract
An ionization system for emitting positive and negative ions includes a first ionizer unit having at least one positive ion emitter, at least one negative ion emitter, a positive power supply connected to the at least one positive ion emitter, a negative power supply connected to the at least one negative ion emitter, a feedback control circuit for controlling power supplied by the positive and negative power supplies based on a feedback signal and an air outlet for emitting positive and negative ions from the positive and negative ion emitters. The system also includes a second ionizer unit having at least one positive ion emitter connected to the positive power supply of the first ionizer unit, at least one negative ion emitter connected to the negative power supply of the first ionizer unit, an air outlet for emitting positive and negative ions from the positive and negative ion emitters, an electrically conductive screen placed between the fan and the ion outlet, a variable voltage supply for supplying a variable voltage to the conductive screen and a sensor for detecting ion emission from the second ionizer unit, wherein the supply of power to the positive and negative ions emitters of the second ionizer unit is controlled by the feedback control circuit of the first ionizer unit.
