<p>A method of preventing rapid on/off of a compressor in a unitary air conditioner comprises the steps of, when a unitary-capacity operation signal (Y) is inputted from a thermostat (51) to start an outdoor unit (55), and a specific operation stage is continued for more than a predetermined period of time after the operation is started, changing the operation stage of the outdoor unit (55) to an operation stage higher than the specific operation stage, and operating the outdoor unit (55) in the changed operation stage, and, when the compressor is stopped according to a signal from the thermostat (51) within a specific period of time after the operation stage is changed to an operation stage higher than the specific operation stage, starting the operation in the specific operation stage at the next operation, and still performing the operation in the specific operation stage although the operation state is continued for more than a predetermined period of time. Consequently, the compressor is prevented from being rapidly turned on/off, and therefore, operational reliability of the compressor is improved, and the service life of the compressor is increased.</p> |
