[0123] The first fan module (210) may be arranged adjacent to the inner side of the second flange (162). The second fan module (215) may be arranged adjacent to the inner side of the fourth flange (164).

[0124] The above ventilation device (10) may include a heat transfer element (220). The heat transfer element (220) is configured so that a first flow path of outdoor air and a second flow path of indoor air exchange heat with each other, and the first flow path and the second flow path may each be provided in multiple numbers and arranged to be stacked on top of each other.

[0125] The air flow flowing through the plurality of first flow paths and the air flow flowing through the plurality of second flow paths can be formed in directions that intersect each other (see arrows in Fig. 12).

[0126] The above heating element (220) has an approximately hexahedral shape, and among the multiple side surfaces of the heating element (220), the first and second side surfaces facing each other form an inlet surface and an outlet surface for outdoor air, respectively, and the third and fourth side surfaces facing each other can form an inlet surface and an outlet surface for indoor air, respectively.

[0127] The above heating element (220) can be placed approximately in the center of the internal space of the housing (100).

[0128] The main body (150) may include a plurality of filters (231, 232, 233). The plurality of filters (231, 232, 233) may include a first filter (231) arranged in an outdoor air flow path. The first filter (231) may be arranged on the inside of a third flange (163) forming an outdoor air intake portion and may be arranged on the inlet side of the heat transfer element (220). Therefore, the outdoor air sucked through the third flange (163) may pass through the first filter (231) and flow into the first flow path of the heat transfer element (220).

[0129] The above-described plurality of filters (231, 232, 233) may include a second filter (232) arranged in a flow path of indoor air. The second filter (232) is arranged on the inner side of the first flange (161) forming an intake portion of indoor air and may be arranged on the inlet side of the heating element (220). Accordingly, indoor air drawn in through the first flange (161) may pass through the second filter (232) and flow into the second flow path of the heating element (220).

[0130] The first filter (231) may be positioned so as to face the first side forming the outdoor air inlet surface of the heating element (220). The second filter (232) may be positioned so as to face the third side forming the indoor air inlet surface.

[0131] The above first filter (231) and second filter (232) can constitute a “pre-filter”.

[0132] The above-described plurality of filters (231, 232, 233) may include a third filter (233) arranged in the outdoor air flow path. The third filter (233) may be arranged on the discharge side of the first filter (231) and the inlet side of the heat transfer element (220). Accordingly, the outdoor air sucked through the third flange (163) may sequentially pass through the first filter (231) and the third filter (233) and flow into the first flow path of the heat transfer element (220).

[0133] For example, the third filter (233) may constitute a “HEPA filter.”

[0134] The above ventilation device (10) may include a PCB device (260) including a control component for the operation of the ventilation device (10). For example, the PCB device (260) may be placed in a space between the first and second fan modules (210, 215) and mounted on a PCB bracket (119, 129).

[0135] The above ventilation device (10) may include a bypass blocking plate (240) to block the sucked outdoor air from being bypassed to the indoor air path side or to block the sucked indoor air from being bypassed to the outdoor air path side.

[0136] The above bypass blocking plate (240) may include a first blocking plate (240a) positioned between the intake side of indoor air and the second fan module (215) and a second blocking plate (240b) positioned between the intake side of outdoor air and the first fan module (210).

[0137] The first blocking plate (240a) may be placed in the space between the first flange (161) and the fourth flange (164), and the second blocking plate (240b) may be placed in the space between the third flange (163) and the second flange (162).

[0138] By means of the first blocking plate (240a), indoor air sucked in from the first flange (161) can be prevented from bypassing the heating element (220) and flowing toward the second fan module (215).

[0139] However, the first blocking plate (240a) may include an openable flap. When the flap is opened, indoor air sucked in from the first flange (161) bypasses the heating element (220) and can be supplied to the indoor space through the second fan module (215) and the fourth flange (164).

[0140] By means of the second blocking plate (240b), the outdoor air sucked in from the third flange (163) can be prevented from bypassing the heating element (220) and flowing toward the first fan module (210).

The vertical length of the filter (231, 232, 233) according to the present embodiment may have a second length (L2).

[0157] For example, the second length (L2) may be the same as the first length (L1).

[0158] The length (L1) of the above heating element (220) or the length (L2) of the above filter (231, 232, 233) may correspond to the vertical height (H1+H2) of the above housing (110, 120).
