In the housing, by mounting the inlet at the lower end and the outlet at the upper end, hot summer air, which has a synergistic effect due to low density, can be introduced to the lower end and discharged to the upper end, thereby reducing the incoming outdoor air to room temperature. can be adjusted to be closer. In addition, by mounting the inlet at the upper end and the outlet at the lower end of the housing, cold air in winter, which has a high density and lowering effect, can be introduced to the upper end and discharged to the lower end. It can be adjusted to be close to the temperature. That is, it is possible to maximize the thermal convection phenomenon of the outdoor air.

In one example, the inlet and outlet may face diagonally. Specifically, the inlet is mounted on the lower end of the first side 1110, the outlet is mounted on the upper end of the second side 1120 facing the first side, and by rotating the upper and lower surfaces of the housing, the upper and lower surfaces of the housing are mounted on the upper end of the first side. The inlet may be mounted, and the outlet may be mounted at the lower end of the second side facing the first side. By facing the inlet and outlet in the diagonal direction, hot air in summer, which has a synergistic effect due to low density, can be introduced to the bottom and discharged to the top, and cold air in winter having a high density, which has a descending effect, is introduced to the top. It can drain to the bottom. As a result, the incoming outdoor air can be adjusted to be close to the indoor temperature.

In another example, the housing may further include an additional inlet on a side facing the inlet. Specifically, the inlet is provided on the first side, the additional inlet is provided on the second side, the inlet and the additional inlet may face parallel to the bottom surface. Since the housing further includes an additional inlet on a side facing the inlet, replacement of the filter unit may be easy.
