PURPOSE: An apparatus for ventilating and purifying indoor air of an underground structure and a control method thereof are provided to autonomously purify by circulating indoor air without operation of a supply fan and an exhaust fan if indoor pollution concentration of the underground structure is above setting value. CONSTITUTION: An apparatus for ventilating and purifying indoor air of an underground structure comprises multiple supply fans(110), multiple exhaust fans(130), and multiple guide fan modules. The supply fans are installed adjacent to supply openings forming in one side of the underground structure. The exhaust fans are installed adjacent to exhaust openings forming in the other side of the underground structure. The guide fan modules guide air, exhausted by the exhaust fans, to the exhaust openings. Each guide fan module comprises a support frame, a guide fan(220), a radial ionizer, a polymer filter, and a radial guide filter. The support frame is fixed on a ceiling of the underground structure. The guide fan is rotatably installed in the rear end of the support frame. The ionizer is installed in the front end of the guide fan. The polymer filter is installed in the front end of the support frame. The guide filter is installed between the guide fan and the polymer filter to reduce velocity of air passing through the guide fan. |
