The control unit (C) may be configured to control the opening and closing of the first damper (410) and the second damper (420). The control unit (C) may control the first damper (410) and the second damper (420) simultaneously or selectively, respectively, to supply air to each chamber (A, B, C).

[0145] The auxiliary discharge channel (210) may include an outlet (65). The outlet (65) may be connected to an auxiliary discharge channel duct (202). The auxiliary discharge channel duct (202) may be connected to an auxiliary discharge duct (200).

[0146] The auxiliary exhaust duct (200) may form at least a portion of the auxiliary exhaust passage (210). The auxiliary exhaust duct (200) may include a first partition (211b) arranged to form a first exhaust passage (211) between it and the first chamber (A). The auxiliary exhaust duct (200) may include a second partition (212b) arranged to form a second exhaust passage (212) between it and the second chamber (B). A third exhaust passage (213) formed between it and the third chamber (C) may be formed by the second partition (212b).

[0147] The first exhaust passage (211) is provided so that air can be discharged directly to the outlet (65) through the first passage (211a) formed in the first chamber bracket (92A). The second exhaust passage (212) is provided so that air can be discharged directly to the outlet (65) through the second passage (212a) formed in the second chamber bracket (92B). The third exhaust passage (213) is provided so that air can be discharged directly to the outlet (65) through the third passage (213a) formed in the third chamber bracket (92C).

[0148] The first exhaust passage (211), the second exhaust passage (212), and the third exhaust passage (213) are each partitioned by the first partition (211b) and the second partition (212b), respectively, so that the air can be discharged separately without mixing.

[0149] Accordingly, air introduced into each chamber (A, B, C) through the air supply path (300) allows some of the outside air to be moved to other chambers (A, B, C) through the discharge path (100a) of the main duct (100), and some of the other air can be discharged to the outside through the auxiliary discharge path (210).

[0150] In this way, some of the outside air flowing into multiple chambers (A, B, C) can be used, and the remaining portion can be moved to other chambers (A, B, C) using the discharge path (100a) of the main duct (100), thereby allowing air to be selectively supplied to each chamber (A, B, C), reducing the number of parts such as dampers or valves, and simplifying complex control algorithms.

[0152] Specific embodiments have been illustrated and described above. However, the invention is not limited to the embodiments described above, and those skilled in the art may make various modifications without departing from the essence of the technical concept of the invention as described in the following claims.
