PURPOSE: An automatic controlled cooling system is provided to stably operate a cooling system in an optimal state because high or low temperature refrigerant is supplied to a compressor in real time by complexly considering the temperature and pressure of the refrigerant. CONSTITUTION: An automatic controlled cooling system comprises refrigerant circulating lines(A1,A2,A3,A4,A5), a compressor(10), a condenser(20), an expansion valve(30), an evaporator(40), and a low temperature refrigerant supplying unit. The compressor is installed in the refrigerant circulating line and compresses refrigerant. The condenser is installed in the refrigerant supplying line and condenses the refrigerant compressed by the compressor. The expansion valve installed in the refrigerant circulating line allows the refrigerant condensed in the condenser to drop in the pressure and controls the amount of the refrigerant. The evaporator is installed in the refrigerant circulating line and evaporates the refrigerant flowing in through the expansion valve by absorbing external heat. The low temperature refrigerant supplying unit supplies relatively low temperature refrigerant to the compressor according to the super heat degree of the refrigerant.
