PURPOSE: To guide the upstream air stream of the connection part of cross flow fans to reduce the deviation of the speed distribution, by providing a partition panel at right angles against the rotary axis of a plurality of cross flow fans coaxially connected, extending from the connection part of mutually adjacent cross flow fans to the upstream side of the air flow. CONSTITUTION: A plurality of cross flow fans 1A, 1B (two in the figure) are coaxially connected together and arranged in the casing 2 of an airconditioner. In this time, the middle of opposite end faces 9A, 9B of respective cross flow fans 1A, 1B are recessed to lessen the clearance δ between the end faces 9A, 9B to the utmost. A partition panel 13 is put at right angles against the rotary shaft 6 to extend from the connection part C to the upstream side until it reaches the nearby position of the upper edge of the heatexchanger 4. The partition panel 13 is used in common as a support plate for a bearing 8 and used to divide the air path from the downstream of heatexchanger 4 to the cross flow fans 1A, 1B into two paths. By such a guide of air stream, the deviation of speed distribution is reduced. |
