PURPOSE: A refrigerator for draft beer is provided to measure an accurate temperature of a refrigerating container by using an electronic sensor and to correctly confirm the operating state of a draft beer refrigerator by installing a display device. CONSTITUTION: A draft beer refrigerator comprises a sensor(120) to measure the temperature of the cooling water filled in a refrigerating container(150) and generate an electrical temperature signal, a user set-up unit(160) to set up the temperature of the refrigerating container, a comparing unit(130) to compare the temperature signal of the sensor to the predetermined temperature and generate a comparison signal, a switch(140) to operate a compressor(170) by transmitting a motion signal to the compressor when the sensed temperature is higher than the predetermined temperature, a temperature display(180) to display the sensed temperature, an agitator motor state display(190) to show the motion state of an agitator motor(220), and a power state display(210) to display the state of a power supply.
