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.

摘要： Disclosed are compressor-controlling device and method for an air conditioner comprising a plurality of compressors. In case several compressors selected from the plural compressors are stopped for a long period of time according to cooling or heating load, the refrigerant contained in a higher-pressure state inside of the stopped compressors moves toward a refrigerant pipe of a lower-pressure inlet port, and oil used to operate the compressors leaks toward the inlet port, thus lowering the oil level within the stopped compressors. Since the stopped compressors are operated during a second designated time when stopped time of the stopped compressors exceeds a first designated time, the stopped compressors are protected from damage due to poor lubrication.

摘要： An air conditioning system and a method for operating the air conditioning system, in which a plurality of compressors are simultaneously or selectively operated, based on the difference between a room temperature and a desired temperature generated during a waiting time for re-operation of the compressors. The room temperature varying during the waiting time for the re-operation of the compressors maintained at a stopped state is sensed to determine whether or not an increase in cooling load occurs. Based on the amount of the cooling load, it is determined whether the compressors have to operate simultaneously or selectively. That is, the refrigerant compression capacity of the air conditioning system is determined by reflecting the cooling load caused by a variation in room temperature occurring during the waiting time for re-operation taken until any compressor maintained in a stopped state is re-operated. Accordingly, it is possible to more stably control the room temperature, and to achieve an improvement in the comfortableness of the room atmosphere.
