摘要： In an apparatus and a method for controlling operation of a compressor, by removing deviation generated by resistance and inductance and removing an error in a stroke estimation value of a compressor, operation of the compressor can be accurately controlled. The apparatus includes a counter electromotive force detector for detecting a counter electromotive force generated at a motor of a compressor. A stroke calculator calculates a stroke estimation value of the compressor on the basis of the counter electromotive force, and a stroke controller controls a stroke of the compressor by varying a voltage applied to the motor on the basis of the calculated stroke estimation value and a stroke reference value.

摘要： An apparatus and a method are disclosed for controlling operation of a compressor capable of greatly decreasing a stroke estimation error of a compressor and controlling operation of the compressor accurately and precisely. The method includes calculating a first stroke estimation value of a compressor on the basis of current, a voltage applied to a motor of a compressor and preset parameters of the motor. Detecting a counter electromotive force of the motor and calculating a second stroke estimation value of the compressor on the basis of the detected counter electromotive force value. Determining a new stroke reference value by comparing the first stroke estimation value with the second stroke estimation value, adding or subtracting a stroke compensation value corresponding to the comparison result to or from a preset stroke reference value, and controlling a stroke of the compressor by varying a voltage applied to the motor on the basis of the determined stroke reference value and the first stroke estimation value.

摘要： According to a method of controlling a refrigerator in accordance with the present invention, after the refrigerating chamber and the freezing chamber are operated at the same time, refrigerant recovery is performed and the refrigerating chamber is then cooled. Accordingly, imbalance due to the pressure difference between the refrigerating chamber evaporator and the freezing chamber evaporator can be solved. Further, there is an advantage in that the refrigerating chamber can be cooled rapidly since refrigerant is supplied to the refrigerating chamber smoothly.
