<P>PROBLEM TO BE SOLVED: To provide a refrigerator that can achieve power saving and improving reliability. <P>SOLUTION: A refrigerator 1 includes first and second chilled air passages 7 and 8 communicating with each other through a damper 15 and a cooling device 11 arranged in the first chilled air passage 7. The refrigerator drives a compressor 10 when one of a refrigeration chamber 3 and a freezer chamber 4 or both of them come to a predetermined upper-limit temperature or higher and stops the compressor 10 when one of the refrigeration chamber 3 and the freezer chamber 4 or both of them falls to a predetermined lower-limit temperature or below. It provides a high speed operation mode which drives the compressor 10 at a predetermined rotational speed and a low speed operation mode which drives the compressor 10 at a rotational speed lower than that of the high speed operation mode. In the low speed operation mode, a difference between an upper-limit temperature tf1 of the freezer chamber 4 and a lower-limit temperature tf2 is set smaller than that during the high speed operation mode, and when the damper 15 is opened, an air volume of the second chilled air passage 8 is set to be smaller than that during high speed operation mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
