A refrigerator and a method for controlling the same are disclosed. The refrigerator may minimize the size and material cost of the control system by controlling the internal temperature and the speed of a compressor using a thermostat used in the conventional low-capacity/low-cost refrigerator without using a system controller equipped with various sensors (internal sensors and/or external sensors) capable of controlling the internal temperature. In addition, since an inverter controller capable of controlling a BLDC compressor estimates the internal/external temperature based on operation information of the compressor, and determines the internal load, it may save energy and reduce vibrations and noise, which are the largest disadvantages of a constant-speed compressor, thereby improving satisfaction of the consumer. In addition, the BLDC compressor may be started and operated stably by applying a differentiated algorithm of the inverter controller.

Refrigerator having variable speed compressor and control method thereof

Embodiments of the present disclosure relate to refrigerators and methods of controlling the refrigerators. The refrigerator comprises a compressor configured to operate at a first rotation speed and a controller configured to calculate a first average of levels of electric signals input to the compressor during a first reference period, and control the compressor to operate at a second rotation speed higher than the first rotation speed when the first average is greater than a first reference value.
