Abstract

A ROOM AIR CONDITIONER INDOOR UNIT WHICH RUNS QUIETLY WITH REDUCED POWER REQUIREMENTS DUE TO MEASURES TO INCREASE THE AIR FLOW RATE AND REDUCE NOISE IN A CROSS FLOW FAN (1). IN A CROSS FLOW FAN (1) WITH BLADES (12) ON A DISK (13), THE CAMBER LINE (17) WHICH REPRESENTS THE CENTER OF THE BLADE THICKNESS IN A CROSS SECTION OF THE BLADE COMPRISES TWO ARCS WHICH ARE OPPOSITE TO EACH OTHER IN THEIR CAMBER DIRECTIONS, PRESSURE FACES OF THE BLADES MATCH THE DIRECTION OF THE AXIS OF ROTATION. THE BLADE (12) THICKNESS IS DESIGNED IN A WAY THAT THE INTER-BLADE FLOW PATH WIDTH ON THE BLADE OUTER EDGE SIDE IS IN THE RANGE OF 60-80% OF THAT ON THE BLADE INNER EDGE SIDE.
