The invention relates to a refrigerator having multiple temperature zones. A refrigerating chamber is located at the upper half part of a refrigerator body of the refrigerator; a freezing chamber and a variable temperature chamber are located at the lower half part of the refrigerator; a condensation section pipeline of a hot-end gravity heat pipe is upwards arranged on the inner side of the left wall surface of a casing of the refrigerator; evaporation section pipelines of a cold-end gravity heat pipe are downwards arranged on the back wall surface and left and right wall surfaces inside the variable temperature chamber; a condensation section of the cold-end gravity heat pipe is connected with a cold end of a free-piston Stirling cooler by the aid of a cold conduction copper sleeve; and an evaporation section of the hot-end gravity heat pipe is connected with a hot end of the free-piston Stirling cooler by the aid of a heat conduction copper sleeve. The free-piston Stirling cooler has the characteristics of wide cooling temperature zone, compact structure, high low-temperature cooling efficiency and the like and enables the variable temperature chamber to realize the lowest temperature of subzero 60 DEG C through combination with the advantages of high heat transfer efficiency and simple structure of the gravity heat pipes. According to the novel refrigerator having the multiple temperature zones, different cooling temperatures inside the refrigerator can be accurately controlled through adjustment of the working frequency of a variable frequency compressor and the input voltage of the free-piston Stirling cooler.
