1. A VOC reduction system comprising:
a housing having an inlet and an outlet formed such that gas is introduced and discharged therethrough;
an adsorption/desorption module disposed in the housing to adsorb/desorb volatile organic compounds (VOC) included in the gas;
a VOC front-end sensing unit disposed on one side of the adsorption/desorption module to sense the concentration of VOC adsorbed by the adsorption/desorption module;
a catalyst disposed on the other side of the adsorption/desorption module to oxidize VOC desorbed by the adsorption/desorption module;
a heating carrier disposed on one side of the catalyst to supply thermal energy directly to the catalyst; and
a VOC rear-end sensing unit disposed behind the heating carrier to sense the concentration of VOC converted by the catalyst,
wherein the heating carrier further includes a heating means supplying pulse type thermal energy, and
the heating means is associated with the VOC front-end sensing unit, and applies the pulse type thermal energy to the heating carrier when the VOC concentration sensed by the VOC front-end sensing unit is sensed as a predetermined value or higher.
