<P>PROBLEM TO BE SOLVED: To provide a refrigerator capable of saving power and of preventing abnormal noise during passage of a refrigerant. <P>SOLUTION: The refrigerator 1, which includes a compressor 10 to be inverter-controlled and driving a refrigeration cycle by flowing the refrigerant and a cooler 11 disposed in a cold temperature part of the refrigeration cycle, drives the compressor 10 when storage compartments 3, 4 are at high temperature higher than predetermined upper limit temperature to cool the inside of the storage compartments 3, 4 by cold air with its heat exchanged with the cooler 11, and stops the compressor 10 if the storage compartments 3, 4 are at low temperature lower than predetermined lower limit temperature, and has a low speed operation mode for driving the compressor 10 at rotation speed N1 when the outside air temperature is at lower temperature than the predetermined temperature, and a high speed operation mode for driving the compressor 10 at rotation speed N2 higher than the rotation speed N1 when the outside air temperature is higher temperature than the predetermined temperature, and is provided with a speed reduction period T for driving the compressor 10 at rotation speed N3 lower than the rotation speed N2 at the start of the high speed operation mode for predetermined time, and switches the rotation speed to the rotation speed N2 after completion of the speed reduction period T. <P>COPYRIGHT: (C)2013,JPO&INPIT |
