PURPOSE:To prevent giving bodily feeling that air is cold to the human body due to a fall of a blow-off air temperature from occurring, by a method wherein the blow-off air temperature is detected to operating capacity of a compressor to be decided by a room temperature by providing a device detecting the room temperature and the blow-off air temperature, the capacity of the compressor is degraded at least by one step when an increasing temperature exceeds a first given value and it is upgraded at least by one step when a decreasing temperature exceeds a second given value. CONSTITUTION:When Ts is given as a given value of a room temperature, operation is started at a time t0 and operated at 75Hz, a blow-off air temperature is stabilized by exceeding 52 deg.C, the room temperature is arrived at Ts-1 at a time t1, operation frequency is changed to 60Hz and the blow-off air temperature is between 40 deg.C and 52 deg.C. When the room temperature is arrived at Ts at a time t2, detection of the blow-off air temperature is started by a temperature sensor by starting control of the blow-off air temperature simulatneously with starting of the operation at 45Hz, the operation frequency is changed to 30Hz when the room temperature exceeds Ts+1 and when the blow-off air temperature becomes less than 40 deg.C at a time t4 control of the blow-off air temperature is performed by changing the operation frequency to 45Hz. When the room temperature is arrived at Ts+2 at a time t5 an air compressor is suspended in its operation and the control of the blow-off air temperature is released, too. |
