Abstract

본 발명은 고풍량 횡류팬 익근차에 관한 것으로, 익형의 외주각(β0)이 25˚∼35˚, 내외경비(DE/Dl)값이 0.75∼0.80, 현절비(T/L)가 0.65∼0.70 범위로 설정되는 횡류팬 익근차를 찌공한다 이러한 횡류팬은 종래의 횡류팬 보다 풍량이 증대하였으므로 회전수 저감에 따른 저소음화가 가능하며, 실제로 94"분리형 에어콘 실내기에 적용되어 기존 에어콘 실내기 보다 3dB 정도 소음 저감 효과를 얻을 수 있었다.The present invention relates to a high air flow crossflow fan blade difference, the outer circumferential angle (β 0 ) of the airfoil, 25 ° ~ 35 °, the internal / external ratio (DE / Dl) value of 0.75 ~ 0.80, the feast ratio (T / L) 0.65 This crossflow fan has a higher air volume than the conventional crossflow fan, which enables lower noise by reducing the number of revolutions. A noise reduction effect was obtained.
