PURPOSE:To provide a wide range of stabled blowing flow from the air conditioning device and further provide a positive adhering of the fluid by arranging a fluid element at a portion where a distribution of flowing speed is relatively uniform in a cross-flow fan blowing port. CONSTITUTION:Fluid element 5 is arranged at the sections A1-A2 where a longitudinal flow speed at the blowing port of the cross-flowing fan 1 is substantially uniform. This fluid element 5 is constituted by the side plates 6 and 7 spaced apart in a logitudinal direction of the blowing port, and the side plates 10 and 11 having the inside surfaces 8 and 9 with expanding forwardly. Flowing inlet port 12 is formed at the rear part of the device and a flowing outlet 13 is formed at the front part of the device, controlling ports 14 and 15 are arranged in a longitudinal direction of the blowing outlet of the fan 1 at a position adjacent to the inlet port 12 of said side plates 10 and 11. The controlling ports 14 and 15 are contorlled for its opening and closing against the surrounding air. It is possible to provide a positive adhering operation of the fluid by the fluid element 5 and further to blow out the blowing air flow from the air conditioning device. |
