Abstract: PURPOSE:To reduce the operating time of a cooling mechanism by comparing the tendency of the change in actual room temperature with a target temperature as its reference thereby strictly determining cooling capacity according to the actual change in room temperature. CONSTITUTION:When an automatic switch 15 is turned ON, an initial set signal C is generated by a single stabilization multi circuit 46 of an ON-OFF condition judging circuit 24 in a compressor controlling circuit 23.
