PURPOSE: A control circuit is provided, in which a condenser is connected in parallel to a compressor and a condenser fan so as to improve power factor of the cooler, to thereby improve energy efficiency and reduce power consumption. CONSTITUTION: A control circuit comprises a driving relay(RY3) for receiving a ventilation signal(VENT), a magnetic switch(MC3) turned on/off by the driving relay, an evaporator fan(EF) driven by a driving power(AC) received through the magnetic switch(MC3), a driving relay(RY1) for receiving a half-cooling signal(HALF) through an automatic/manual selection switch(THCGS1) or a temperature controller(TH1) connected in parallel, a magnetic switch(MC1) turned on/off by the driving relay, a compressor(CP1) and a condenser fan(CF1) connected to a condenser(CPT1) so as to be driven by the driving power(AC) received through the magnetic switch(MC1), a driving relay(RY2) for receiving a full-cooling signal(FULL) through an automatic/manual selection switch(THCGS2) or a temperature controller(TH2), a magnetic switch(MC2) turned on/off by the driving relay(RY2), and a compressor(CP2) and a condenser fan(CF2) connected to a condenser(CPT2) so as to be driven by the driving power(AC) received through the magnetic switch(MC2).
