PROBLEM TO BE SOLVED: To eliminate the problem with prior art that a room air conditioner using a reflux fan as a fan for an indoor machine can be improved in performance of a heat exchanger by converting the air volume to a high level, but a noise level is raised in accordance with such a high air volume. SOLUTION: A reflux fan 7 is adapted such that air sucked from openings 1, 2 in the front surface and in the upper surface of an indoor machine is diffused from a nozzle at a lower portion of the indoor machine through heat exchangers 3, 4, 5. The reflux fan 7 is provided on a downstream side from the heat exchangers 3, 4, 5. An angle is set over 180 degree at the heater exchanger side in the vertical section, at the intersection of the line between the extremity of the front nose 8 and the center of the shaft of the reflux fan 7 and the line between the rear nose 7 and the center of the fan shaft. |
