Abstract
A refrigerator control method is disclosed which ensures efficient operation of a compressor. To control a refrigerator including a compressor, a first evaporator and a second evaporator connected to the compressor, and a refrigerant control valve that controls introduction of a refrigerant into the first evaporator and the second evaporator, the refrigerator control method includes operating the compressor, and controlling the opening and closing of the refrigerant control valve, to reduce not only consumption of electricity by the compressor, but also a pressure difference between an entrance and an exit of the compressor upon starting of the compressor.
