A system and method for regenerative air purification technology use in residential or commercial HVAC systems that includes a set of gas sensors and processor, a set of filters including the pre-particles filter; HEAP particles filters and the adsorption gas filters with TiO2 (or TiO2 mixed activated carbon material) coated on the outer surface, a set of auto valves, a set of UV Lamps on the boundaries of device compartment, a set of heater located in the central of a cylinder type of adsorption filter. The air is ventilated through the pre-particle filter, “HEPA” filter or a high efficiency filter with nano-material fibers (HENF) and combined activated carbon adsorption filter via a well designed manifold tube, in which the particles will be captured on the pre-particle filter and “HEPA” or “HENF” filter materials and VOCs are trapped by the adsorption filter. The processor is configured to receive input data from gas sensors, to compare the predetermined threshold and sending signals to auto valves in the compartment of device. During the air cleaning phase, when the input data from gas sensors reaches the predetermined threshold, the auto valves are controlled through the signals that sent by processor to change the air cleaning phase to the regenerative phase. During the regenerative phase, the UV lamps and heater in the central location of cylinder type of adsorption filter are turned on and the situated adsorption filter media will be cleaned up via the combined approaches including the heater, PCO technology and the reversed air flow. In addition, the pre-particle filter and “HEPA” or “HENF” filter materials are also can be cleaned up via a reversed air flow during the regenerative phase in the present invention. |
