Provided is a refrigerator adopting a linear compressor and control method thereof. The control method comprises: monitoring a temperature of a refrigerator evaporator; if the current temperature of the refrigerator evaporator is equal to or greater than a first temperature threshold, then invoking a noise reduction mode, automatically reducing the amount of heat exchange between the evaporator and refrigerator chamber, and invoking a refrigeration mode until the current temperature of the refrigerator evaporator is less than or equal to a preset second temperature threshold, and then restoring the evaporator and refrigerator chamber to normal heat exchange, wherein, the first temperature threshold is higher than second temperature threshold. When there is a large heat load, the control method closes an evaporator damper and/or a fan, causing a reduction in the heat exchange rate of the evaporator, such that the temperature of the evaporator decreases quickly, and linear compressor suction and exhaust pressure decreases accordingly, ultimately causing a reduction in the vibration frequency of the linear compressor, such that it does not readily resonate with the refrigerator container body, and thus has low operating noise.
