<P>PROBLEM TO BE SOLVED: To provide a control means capable of controlling a rotating speed of a compressor according to a load, even if in a refrigerator having no control means for deciding the rotating speed of operating the compressor, from a difference between an in-chamber temperature and a setting temperature. <P>SOLUTION: A compressor control device includes: setting a time of a timer 121 according to a motor current detected by a motor current detection means 122 during an operation of a DC motor 107; controlling the rotating speed based on the load, if the setting time comes, in order to increase the rotating speed of the DC motor 107; operating at a high rotating speed quickly when decided that the load of the refrigerator is large; and enabling an energy saving operation at a low rotating speed when the load is small. <P>COPYRIGHT: (C)2013,JPO&INPIT |
