PURPOSE:To obtain a jet spread preventing effect sending cool air to each corner of a vehicle room and obtain a comfortable air conditioned state by making a bypass air blow out while enclosing a blow out air in an air conditioning device having a bypass. CONSTITUTION:When a bypass damper 31 is opened while turning on an air conditioner switch, air is introduced from an open air intake port or an inside air intake port into an air conditioner duct 1 by means of a blower 6. This air is cooled and dehumidified while passing through an evaporator 8, and mostly, blown out of a ventilation blow out port 13 through a duct 1 as a main bow out air stream (a). The remaining part flows into the introducing part 30a of a bypass air passage 30 to become a sub-blow out air stream (b) and blows out of the end of an enclosing air stream forming duct 32 in such a way that it encloses the main blow out air stream (a). Thus, by enclosing the main blow out air stream (a) with the sub-blow out air stream (b) having a relatively low flow velocity, a jet spread preventing effect can be obtained. |
