The present invention relates to a multi-convection ventilation apparatus comprising a ventilation fan unit (1) ventilating indoor air, and adhering to a ceiling board (u) by horizontally suspended on a concrete beam (cb) by supporting rods (r); a counter flow-type heat exchange unit (2) recovering waste heat by heat exchange during the exhaust of indoor air and the supply of outdoor air; and a dust collecting unit (3) and an air supply fan unit (4) arranged in series inside a housing (5), wherein the dust collecting unit (3) has a UV sterilizing lamp (3r) with a photo-catalyst supplying fresh air by filtering out and sterilizing dust in the supplied outdoor air. According to the present invention, the multi-convection ventilation apparatus has a simple structure to conveniently install the multi-convection ventilation apparatus, and can be easily manufactured by being applied with existing respective units. In addition, according to the present invention, the ventilation fan unit (1) has a ventilation fan (1f), an air supply diffuser (1b), and an air exhaust diffuser (1d) for the convection of the indoor air, the heat exchange unit (2) performs the heat exchange, and the dust collecting unit (3) prevents heat loss, and sterilizes and filters the outdoor air in order to supply the fresh air indoors, thereby hygienically improving the health of a user. |
