摘要： A unitary air conditioner comprises a 1-stage thermostat mounted in a room for generating an air conditioner ON/OFF signal, an indoor unit configured to operate based on a signal from the 1-stage thermostat, and a variable-capacity outdoor unit connected to the 1-stage thermostat and the indoor unit. The variable-capacity outdoor unit has variable operation stages, which are changed based on the previous operation state and the current operation state. When a unitary-capacity operation signal is inputted from the 1-stage thermostat, a start operation stage of an outdoor unit is determined based on the combination of the operation stage of the outdoor unit operated before the operation signal is inputted and the operation time in the stage, and the determined operation is performed. The 1-stage thermostat can be connected to the variable-capacity outdoor unit according to circumstances.

摘要： Disclosed is a method for operating an air conditioner in a warming mode, including the 100% operation performing step of operating/stopping all of compressors, the load determining step of determining a warming load to be eliminated after completion of the 100% operation performing step, the 100%/X% operation performing step of operating all of the compressors when it is determined at the load determining step that the warming load is not large, subsequently stopping a part of the compressors, and subsequently stopping the remainder of the compressors, the sensing step of sensing the number of stoppages of the remainder of the compressors after completion of the 100%/X% operation performing step, and the X% operation performing step of operating/stopping the remainder of the compressors when the sensed number of stoppage times reaches a predetermined number. Since the 100%/X% operation is carried out in response to a warming load generated after the 100% operation, this method properly copes with the warming load at an initial stage of the warming mode. Further, since the X% operation is carried out after the 100%/X% operation is repeated in a predetermined number, the method of the present invention precisely and promptly copes with the variation of the warming load.

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.
