PROBLEM TO BE SOLVED: To prevent mist from blowing out in an indoor unit and condensation from being produced on an indoor side fan independently of temperature and humidity in a room by altering a set value of operation frequency of a compressor in response to outputs from an operation time comparator means and an indoor blowoff temperature comparator means, and controlling the compressor with an output of the altered set value. SOLUTION: When cooling operation is started, operation time is detected by an operation time detection means 101, and indoor blowoff temperature is detected by an indoor blowoff temperature detection means 120. The operation time detected by the operation time detection means 101 and a set time previously set by a set time memory means 102 are compared with each other by a comparator means 103. Further, the indoor blowoff temperature detected by the indoor blowoff temperature detection means 120 set indoor blowoff temperature previously set by a set indoor blowoff temperature memory means 121 are compared with each other by a comparator means 122. The set value of the operation frequency of the compressor 106 is controlled in response to the foregoing outputs by an operation frequency set value output means 104, and the compressor is operated by a driver circuit 105. |
