Abstract

A refrigerator with a main body including a refrigerating compartment at a temperature higher than a freezing temperature and a freezing compartment at a temperature lower than the freezing temperature, a deep-freezing storage chamber within the main body at a temperature lower than that of the freezing compartment. The refrigerator further includes a compressor, a condenser connected to an outlet-side of the compressor, a first expansion valve connected to an outlet-side of the condenser, a first evaporator connected to an outlet-side of the first expansion valve, and a heater disposed outside the first expansion valve.
