Air purifying system

An air purification module for use in an air passage of an air handling unit of a central air-conditioning system, the air purification module (100) comprising

• a first housing (200):
• the first housing (200) comprises a closed surface (202), an air inlet surface (204) and an air exhaust surface (206) to allow airflow;
• a panel member (300):
• wherein each panel of the panel member (300) is detachably installed inside the first housing (200);
• a short-wave ultraviolet lamp member (400) wherein the short-wave ultraviolet lamp member (400) is installed inside the first housing (200);
• a control unit (500) wherein the control unit (500) is installed a second housing (210) outside of the first housing (200);
• and
• a high voltage direct current generator (600) adapted to provide a pulsed direct current electric field, wherein the high voltage direct current generator (600) is installed in a third housing (220) outside of the first housing (200), wherein the pulsed direct current electric field is a high voltage pulsed direct current electric field of 20,000 volts/cm or more,
• wherein the panel member (300) comprises
• a first panel (310) comprising a pre-filter panel (312);
• a second panel (320) comprising a first foam metal panel (322) and a second foam metal panel (324) adjacently installed, the first foam metal panel (322) and the second foam metal panel (324) are respectively connected to positive and negative electrodes of the high voltage direct current generator (600), wherein the first foam metal panel (322) and the second foam metal panel (324) are separated by a gap of at least 15 cm;
• a third panel (330) comprising a plurality of third foam metal panels (332) having a photocatalyst coating,
• wherein the first panel (310), the second panel (320) and the third panel (330) are sequentially arranged in parallel in a direction from the air inlet surface (204) to the air exhaust surface (206),
• wherein the high voltage pulsed direct current electric field of 20,000 volts/cm or more is capable of instantly killing contaminants which are captured in the first foam metal panel and the second foam metal panel upon discharge of the high voltage pulsed electric field, wherein only the first foam metal panel (322) is connected to the positive electrode of the high voltage direct current generator (600), wherein only the second foam metal panel (324) is connected to the negative electrode of the high voltage direct current generator (600), and wherein the positive electrode of the high voltage direct current generator (600) and the negative electrode of the high voltage direct current generator (600) are the only electrodes of the air purification module.
