PURPOSE:To improve flow rate performance in which a suction part of a crossflow fan is increased and to reduce noise by arbitrarily bending a heat exchanger and providing a suction cover on a back surface. CONSTITUTION:Heat exchangers (7a, 7b) are arbitrarily bent and a suction cover 5c is provided on a back surface. Thus, the air sucked from front parts of a front suction cover 5a and an upper suction cover 5b is passed through an air filter 8 and further the exchanger 7a to be sucked. The air sucked from a rear part of the cover 5b and the cover 5c is passed through the filter 8 and further the exchanger 7b to be sucked. These sucked airs are passed through an air passage formed of a single impeller 2, a rear guide 3 and a stabilizer 4 formed around the impeller 2, and diffused from a diffuser 6. Thus, flow rate performance is improved, and a flowing field having small disorder can be formed. |
