    摘要: A method for controlling multiple compressors for use in an airconditioner is disclosed. In the airconditioner having N compressors, the method sequentially and equally operates the N compressors using a two-dimensional matrix which prevents only a specific compressor from among the N compressors from being repeatedly operated, arranges rows and columns of the two-dimensional matrix to allow all compressors to be alternately operated according to the number of operating compressors from among all compressors, and stochastically operates and stops the N compressors using the two-dimensional matrix. As a result, the method controls the N compressors to be equally operated without overlapping operation times of the N compressors, and alleviates fatigue of the compressors, resulting in equally longer lifetimes of the N compressors.

    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.

    摘要: Disclosed are an apparatus for preventing an overload of an air conditioner and a method thereof. The apparatus includes current feedback units for feeding back the currents supplied to the compressors to the controller where at least one of a plurality of compressors, operated in response to currents generated from a controller for controlling an operation of the air conditioner, is in an overload state; and a comparator for sensing current differences between the currents inputted into the compressors and the currents fed back from the current feedback units. After sensing the current differences between the currents inputted into the compressors and the currents fed back from the current feedback units, the comparator determines that at least one of the compressors is in the overload state if a current difference does not exist. The controller simultaneously stops operations of the compressors, and re-operates the compressors if the overload state is relieved, thereby preventing a continuous overload state of a compressor and hence damage of a compressor.

    摘要: Disclosed is a method for controlling the aperture ratio of a linear expansion valve (LEV) so as to control the flow rate of refrigerant circulating in an air conditioning system. The LEV aperture ratio is controlled to range from the minimum value to the maximum value, which are determined according to the compressor's capacity and the cooling and heating modes. The LEV aperture ratio is controlled also based on the compressor's operating status, the change of the indoor fan's air volume, and whether or not the indoor fan operates. Such LEV control enables refrigerant to always be circulated at a suitable flow rate, improving the cooling and heating efficiencies, and also prevents liquid refrigerant from flowing into the compressor, securing high reliability of the compressor.

    摘要: Disclosed are an air conditioning system with two compressors and a method for operating the same, so as to variably change a compression capacity of a refrigerant according to the variation of cooling load. Herein, when a full operation order is inputted to the two compressors in order to satisfy increased cooling load, the first compressor is first operated, and then the second compressor having a compression capacity of a refrigerant smaller than that of the first compressor is additionally operated, so that a current peak value for operating the compressors does not exceed an allowable current range of a circuit breaker installed in a home or building, thereby safely controlling the air conditioning system and simultaneously allowing the current to be provided to other electric appliances, thus improving users' convenience.

    摘要: Disclosed herein is a method of controlling a linear expansion valve of a cooling cycle apparatus. The method comprises a first step of calculating a target opening level value according to suction overheat level of compressors to control a linear expansion valve based on the calculated target opening level value, and a second step of calculating a new target opening level value according to the suction overheat level of the compressors and discharge temperature of the compressors to control the linear expansion valve based on the calculated new target opening level value. Consequently, the discharge temperature of the compressors is prevented from being excessively increased, and therefore, the compressors are prevented from being overheated and damaged, and reliability of the cooling cycle apparatus is improved.
