PURPOSE: To deal with drain water with a simple structure without deteriorating the appearance of an installation area and ease of maintenance and inspection operations by providing a drain reservoir for reserving drain water, which is located in the vicinity of a connecting portion with a suction opening and is formed integrally with a duct so as to allow air flow passing through the duct to come in contact with the drain water. CONSTITUTION: Indoor air suctioned through a suction opening 14 of a panel 9 forms condensate in a directly connected duct 16 to constitute drain water, all of which is contained in a drain reservoir 17 due to an inclination provided on the directly connected duct 16. The drain water is always exposed to ventilation flow flowing through the directly connected duct 16 so that evaporation is enhanced and vapor is exhausted together with the exhausting flow. If a drain receiver 13 of the panel 9 is filled with the drain water, the drain water is allowed to flow outside via a relief hole through the suction opening 14 of the panel 9. |
