SUBSTANCE: invention proposes a method for controlling operation of a refrigerator compressor whereby thawing is effected when the temperature inside the refrigerator reaches a predetermined thawing temperature. Refrigerating capacity of the compressor mounted inside the refrigerator is changed depending on the temperature inside the refrigerator by regulating the direction of rotation of the compressor. The refrigerating capacity of the compressor is increased by rotating the compressor in one direction and is decreased by rotating the compressor in another direction, this second direction being reverse to the first one. Prior to thawing the compressor is repeatedly rotated in the second direction and stopped until the predetermined thawing temperature is achieved inside the refrigerator. After thawing the compressor is rotated in the first direction until the predetermined temperature is achieved and in order to maintain this predetermined temperature the compressor is periodically stopped or rotated in the second direction. A device for controlling operation of a refrigerator compressor includes a microcomputer, a working frequency converter, a rotation signal generating unit and a unit for measuring temperature inside the refrigerator. The working range of the temperature measuring unit is predetermined depending on the compressor rotation direction.

EFFECT: reduced power consumption by a refrigerator; increased capacity and precise temperature control of the refrigerator.
