The second inlet 310b is provided on the front or lower surface of the case 310 .

In the case 310, the first inlet 310a and the second inlet 310b should be provided as far apart as possible. This is because the discharge air of the air conditioner must be introduced through the first inlet 310a and the indoor air of the indoor space must be introduced through the second inlet 310b. because it has to be prevented.
