Abstract

AN AIR CONDITIONER HAS A THROUGH-FLOW BLOWER (12) HAVING A PLURALITY OF BLADES (11). A NOSE (3) AND A CASING (4) IN COOPERATION DEFINE A PASSAGE OF AIR UPSTREAM AND DOWNSTREAM OF THE THROUGH-FLOW BLOWER (12). THE AIR CONDITIONER ALSO HAS A HEAT EXCHANGER (6) PROVIDED ON THE SUCTION SIDE OF THE THROUGH-F1OW BLOWER (12). A GRILLE (5) IS DISPOSED ON THE AIR INLET SIDE OF SAID HEAT EXCHANGER (6). EACH BLADES (11) HAS AN ARCUATELY CURVED SECTIONAL SHAPE AND THE RADIALLY OUTER END PORTION OF THE BLADE (11) EXTENDING OVER A PREDETERMINED LENGTH IS BENT SUCH THAT ITS SECTIONAL SHAPE IS INCLINED TOWARDS THE CENTER OF CURVATURE OF THE BLADE (11). THIS SPECIFIC BLADE CONFIGURATION LOWERS THE PEAK LEVEL OF THE NOISE WHICH APPEARS AT A SPECIFIC FREQUENCY EQUAL TO THE PRODUCT OF THE NUMBER OF THE BLADES AND THE BLOWER ROTATION SPEED, WITHOUT BEING ACCOMPANIED BY A REDUCTION IN THE AIR DISCHARGE RATE, AND FACILITATES THE DESIGN OF CONFIGURATION OF THE NOSE, THUS CONTRIBUTING TO REDUCTION IN THE PRODUCTION COSTS.FIGURE 1
