PURPOSE:To automatically control the normal and inverse flow of stream by composing the inside guiding vanes which control the motion of low pressure vortex generated from cross-flow fan, with the temperature sensing deformation members. CONSTITUTION:An inside guiding vane 20 is composed of the temperature sensing deformation members such as bimetal, shape memorizing alloy etc., and the material and the size of the vane are selected so that the shape of the vane can restrict the low pressure vortex generated from a cross-flow fan 5. When the environmental temperature is over a set temperature, the shape of the inside guiding vane 20 is maintained in the form having a concaved part on the left side. The outside flow on the inside guiding vane 20 moves in the direction shown by (a). When the environmental temperature is below the set value, thermal deformation is generated to form the concaved part on the right side of the vane, because the inside guiding vane 20 is made of the temperature sensing member, and the outside flow on the inside guiding vane 20 moves in the direction shown by (a'). |
