摘要： 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 is inputted from a thermostat to start an outdoor unit, 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 to an operation stage higher than the specific operation stage, and operating the outdoor unit in the changed operation stage, and, when the compressor is stopped according to a signal from the thermostat 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.

摘要： An air conditioner incorporates valve devices mounted in a plurality of indoor units, respectively, for allowing refrigerant discharged from an outdoor heat exchanger to be introduced into one or more indoor units that are in operation. The refrigerant is prevented from being introduced into the other indoor units that are not in use, and therefore, oil is prevented from being accumulated in the other indoor units that are not in use. Also, an appropriate amount of refrigerant is supplied to the indoor units that are in operation, and therefore, reliability and efficiency of the air conditioner are improved.
