PROBLEM TO BE SOLVED: To suppress the decrease in the blowoff temperature due to a continuous decline in the amount of wind beforehand, and to prevent the condensation of the blowoff part or the like of an indoor unit and moreover the decline in the amount of the cold air to a room by making a correction through raising the minimum number of the revolutions of an indoor fan on the basis of the detected indoor heat exchanger temperature. SOLUTION: In cooling or dehumidifying operations, each data of detected temperatures To, Te, Ta, Tc and detected humidity Th and a frequency command Hz, which is formed in a control circuit 26 and corresponds to the number of revolutions of a compressor, are read from temperature sensors 34, 36, 38, 42, and a humidity sensor 40, respectively. When it is confirmed to be in an automatic mode, the target number of revolutions Fs of an indoor film 16 is determined on the basis of the difference between the detected room temperature Ta and the set temperature Ts. On the basis of the data that is read before, the minimum number of revolutions F min of the indoor fan 16 is determined. In case that Fs is <F min, the target number of revolutions Fs is corrected to the minimum number of revolutions F min compulsorily, supposing that there are possibilities of condensation or freezing. |
