Abstract: The present disclosure relates to a refrigerator and a method for controlling the same. The present disclosure provides a method for controlling the same, the method including an initial driving step of driving a compressor according to a rotation per minute (RPM) at which the compressor is driven in a previous cycle, an RPM adjusting step of increasing the RPM when an operation rate is larger than a first setting value, decreasing the RPM when the operation rate is smaller than the second setting value, and maintaining the RPM when the operation rate is between the first setting value and the second setting value, in consideration of the operation rate of the previous cycle, and a driving step of driving the compressor according to the adjusted RPM, wherein the first setting value is larger than the second setting value.

Abstract: A control method includes initially operating a compressor at the same RPM as an operating RPM of the compressor during a previous cycle, adjusting the RPM in consideration of an operation rate of the previous cycle such that the RPM is increased when the operation rate is greater than a first set value, reduced when the operation rate is less than a second set value, and maintained when the operation rate is within a range between the first set value and the second set value, and operating the compressor at the adjusted RPM, the first set value being greater than the second set value.
Abstract translation: 控制方法包括：在前一个循环中，以与压缩机的运行RPM相同的RPM开始运行压缩机，考虑到前一循环的运行速率来调节RPM，使得当运行速率大于 第一设定值，当操作速度小于第二设定值时减小，并且当操作速率在第一设定值和第二设定值之间的范围内时保持，并且以调节的RPM操作压缩机，第一设定值 设定值大于第二设定值。

Abstract: A refrigerator includes a cabinet that defines a freezing compartment and a refrigerating compartment, and an evaporator installed in the freezing compartment. The evaporator includes: an evaporator case that defines a food storage space formed therein; a cooling tube located at the evaporator case in a predetermined pattern and configured to receive a coolant; and a sheath heater disposed outside of the evaporator case to be adjacent to at least one surface of the evaporator case, the sheath heater being configured to generate heat such that heat for defrosting is transferred to the evaporator case. The sheath heater reduces the defrosting time to maintain the freshness of food, increases the cooling efficiency, and reduces power consumption. The defrosting efficiency by the sheath heater is improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment is reduced by a heat insulation member.

Abstract: An evaporator includes: an evaporator case that defines a food storage space therein; a cooling tube located at the evaporator case and filled with refrigerant; a foil heater attached to at least one surface of the evaporator case and configured to contact the evaporator case and to generate heat such that heat for defrosting is transferred to the evaporator case. A defrosting time is reduced in comparison to that of conventional natural defrosting, such that the freshness of food can be maintained, and the cooling efficiency, having been reduced by frost, is increased such that power consumption can be reduced. The foil heater is attached to a conventional roll-bond type evaporator case, and the present invention has an advantageous effect of facilitating the maintenance of the foil heater because of a structure in which the foil heater is attached to the evaporator case.
