The plurality of panel brackets 168 and 170 are located at an upper side or a lower side of the upper cover bracket 164 when the front panel 20 is installed, and the upper panel bracket 168 is in contact with the upper cover bracket 164 and the front panel. The installation of the panel 20 may include a lower panel bracket 170 positioned above or below the lower cover bracket 166 and in contact with the lower cover bracket 166.

The plurality of panel brackets 168 and 170 may be fixed to the front panel 20 by welding such as adhesive or spot welding.

The plurality of panel brackets 168 and 170 may have a separation distance greater than that of the plurality of cover brackets 164 and 166 such that the plurality of cover brackets 164 and 166 are positioned therebetween.

The plurality of panel brackets 168 and 170 are spaced apart from the plurality of cover brackets 164 and 166 such that the plurality of panel brackets 168 and 170 are positioned between the plurality of cover brackets 164 and 166. It is possible to have a smaller separation distance.

Referring to the operation of the present invention configured as described above are as follows.

First, when the air supply fans 44 and 46 are driven, outdoor air is sucked into the outdoor air intake chamber 108 through the outdoor air intake port 10. The outdoor air sucked into the outdoor air suction chamber 108 is blown by the air supply fans 44 and 46 to the lower side of the heat exchanger 32 and 34, and then the flow direction is changed to the upper direction. The foreign matter in the outdoor air is filtered by the filters 151 and 152.

The outdoor air passing through the outdoor air filters 151 and 152 is introduced into the outdoor air passages 36 and 37 through the lower surfaces of the total heat exchangers 32 and 34, and the outdoor air passages 36 and 37. Heat exchanged with the indoor air passing through the indoor air passages 38 and 39 while passing through, and then discharged to the upper surface of the total heat exchanger (32) (34). The outdoor air discharged to the upper surfaces of the total heat exchangers (32) and (34) is directly discharged into the room through the outdoor air outlets (12) and (14) of the top cover (22).

The outdoor air is switched once in the left and right directions in the outdoor air suction chamber 108, and then the flow direction is changed once in the up and down directions at the lower side of the total heat exchangers (32) and (34), thereby switching a total of two times. Then discharged into the room.

On the other hand, when the exhaust fan 42 is driven, the indoor air is sucked into the indoor air intake openings 4 and 6, and the foreign air in the indoor air is filtered by the indoor air filters 88 and 90.

The indoor air passing through the indoor air filters (88) and (90) passes through the indoor air passages (38) and (39) of the total heat exchanger (32) and (34) and the outdoor air of the outdoor air passages (36) and (37). The heat exchanger is then sucked into the indoor air exhaust chamber 110 and then sucked into the exhaust fan 42 and then discharged through the indoor air outlet 8.

  The indoor air in the indoor air exhaust chamber 110 is switched once in the forward and backward directions, and is switched only once and then discharged to the outside.
