The present invention relates to a freezing system having two vaporizers for a refrigerator constructed as a single-loop cycle which is capable of using a genuine coolant as well as a mixed coolant by providing the coolant to a compressor after mixing the each coolant passed through a freezing chamber vaporizer and a chilling chamber vaporizer and heightening the pressure. The present invention comprises a compressor, a condenser for condensing the coolant compressed at the compressor, a freezing chamber expanding mean and a chilling chamber expanding mean for depressing the condensed coolant as a first pressure and a second pressure, a freezing chamber vaporizer and a chilling chamber vaporizer for cooling the air to be provided to the freezing chamber and chilling chamber as a first temperature and a second temperature by vaporizing the coolant expanded at the freezing chamber expanding mean and chilling chamber expanding mean, and an ejector for providing the coolant to the compressor after mixing the each coolant passed through the freezing chamber vaporizer and chilling chamber vaporizer and heightening the pressure.
