PROBLEM TO BE SOLVED: To make an air property at a downstream of a nozzle analogous to the property of primary air in an air conditioner that forms a primary air stream by jetting out air to a space to be air-conditioned through the nozzle and uses the primary air stream to form a secondary air stream.SOLUTION: An air conditioner includes a duct 30 through which air fed from a blower flows, and a nozzle 32 that is disposed on an external wall 31 of the duct 30 and forms a primary air stream F1 by jetting out air, which is fed from the blower, to a space to be air-conditioned. The primary air stream F1 flows along an external surface of the external wall 31 of the duct 30, and causes air around the nozzle 32 to be led to the primary air stream F1 in order to form a secondary air stream F2. Herein, in a region of the external wall 31 of the duct 30 in which the primary air stream F1 or secondary air stream F2 flows along the external surface, an orifice 33 through which air inside the duct is fed to outside the duct is formed. |
