A refrigerator having improved cooling and cooling recovery is provided. A main body of the refrigerator may include an outer casing that defines an external appearance of the refrigerator, and an inner casing with an open upper face installed in the outer casing to define a storage space therein. The open upper face of the main body may be opened and closed by a door. The inner casing may include a casing upper portion and a casing lower portion coupled to the bottom of the casing upper portion. The casing lower portion may be formed of a material different from that of the casing upper portion. The casing upper portion may be made of a material having a high thermal conductivity, and the casing lower portion may be made of a material having a lower thermal conductivity that that of the casing upper portion.

What is claimed is: 1. A refrigerator, comprising: an outer casing that defines an external appearance of the refrigerator; an inner casing having an open upper face, wherein the inner casing is installed within the outer casing so as to define a storage space therein, wherein the inner casing comprises: a casing upper portion having open top and bottom faces and four closed lateral side faces; and a separate casing lower portion having an open top face, a closed bottom face, and four closed lateral side faces, wherein an outer peripheral portion of the open top face of the casing lower portion is coupled to a corresponding outer peripheral portion of the open bottom face of the casing upper portion so as to form the storage space within the inner casing, and wherein a material of the casing lower portion has a lower thermal conductivity than a material of the casing upper portion; and a door that selectively opens and closes the open upper face of the inner casing. 2. The refrigerator of claim 1, wherein the material of the casing lower portion has a higher specific heat than the material of the casing upper portion. 3. The refrigerator of claim 1, wherein the casing upper portion is formed of aluminum. 4. The refrigerator of claim 1, wherein the casing lower portion is formed of tin. 5. The refrigerator of claim 1, further comprising an aluminum tape that couples the casing upper portion and the casing lower portion. 6. The refrigerator of claim 1, further comprising: a plurality of refrigerant tubes provided on an outer circumferential surface of the casing upper portion; and a heating element provided on an outer circumferential surface of the casing lower portion. 7. The refrigerator of claim 6, wherein a difference in thermal conductivity of the casing upper portion and the casing lower portion prevents heat in the casing upper portion from being transferred to the casing lower portion. 8. The refrigerator of claim 1, wherein the inner casing comprises a plurality of compartments each having an open upper face, each of the plurality of compartments comprising: a casing upper portion having open top and bottom faces and four closed lateral side faces; and a casing lower portion made of a different material than that of the casing upper portion, the casing lower portion having an open top face, a closed bottom face, and four closed lateral side faces such that the casing upper and lower portions are coupled at mating peripheral portions of their open bottom and top open faces, respectively. 9. A refrigerator, comprising: an outer casing; an inner casing mounted inside the outer casing, wherein a storage space is formed within the inner casing, and wherein the inner casing comprises: a casing upper portion formed of a first material and mounted in an upper portion of the outer casing, wherein the casing upper portion has an open bottom; and a separate casing lower portion coupled to the casing upper portion so as to form the storage space formed within the inner casing, wherein the casing lower portion is formed of a second material that is different from the first material, wherein the first material has a higher thermal conductivity than the second material, and wherein the casing lower portion is mounted in a lower portion of the outer casing; and a door that selectively open and closes the storage space formed in the inner casing. 10. The refrigerator of claim 9, wherein the first material has a lower specific heat than the second material. 11. The refrigerator of claim 9, further comprising a plurality of refrigerant tubes coupled to an outer surface of the casing upper portion. 12. The refrigerator of claim 11, further comprising a heater coupled to an outer surface of the casing lower portion. 13. The refrigerator of claim 9, further comprising a heater coupled to an outer surface of the casing lower portion. 14. The refrigerator of claim 9, wherein the inner casing is shaped to form a plurality of separate storage spaces. 15. The refrigerator of claim 9, wherein the casing upper portion includes an open top and an open bottom, and wherein the casing lower portion comprises an open top and a closed bottom. 16. The refrigerator of claim 15, wherein the casing upper portion is joined to the casing lower portion with an adhesive tape. 17. A refrigerator, comprising: an outer casing that defines an external appearance of the refrigerator; an inner casing installed within the outer casing so as to define a storage space therein, wherein the inner casing comprises: a casing upper portion having open top and bottom faces and four closed lateral side faces; and a casing lower portion that is separate from and coupled to the casing upper portion, wherein the casing lower portion has an open top face, a closed bottom face, and four closed lateral side faces, and wherein an outer peripheral edge of the open top face of the casing lower portion is coupled to a corresponding outer peripheral edge of the open bottom face of the casing upper portion such that corresponding outer peripheral edges of the casing upper and lower portions are flush and form a continuous internal and external contour, wherein a material of the casing lower portion has a lower thermal conductivity and a higher specific heat than a material of the casing upper portion; and a door that selectively opens and closes the storage space defined by the inner casing. 18. The refrigerator of claim 17, further comprising: a plurality of refrigerant tubes provided on an outer circumferential surface of the casing upper portion; and a heating element provided on an outer circumferential surface of the casing lower portion, wherein a difference between the thermal conductivity of the casing upper portion and the casing lower portion prevents heat in the casing upper portion from being transferred to the casing lower portion.
