Claim:
1. A refrigerator comprising: a body including an inner case, an outer case, and a heat insulating material that foams in a space between the inner case and the outer case; a first storage compartment formed in the body; a second storage compartment formed in the body and partitioned off from the first storage compartment; a machine compartment formed in the body and partitioned off from the first storage compartment and the second storage compartment; a blower fan disposed in the machine compartment so as to cool the machine compartment; a first refrigerating unit comprising a first compressor to compress a first refrigerant, a first condenser to condense the first refrigerant, a first expansion valve to expand the first refrigerant, and a first evaporator to evaporate the first refrigerant, the first refrigerating unit supplying cold air to the first storage compartment; and a second refrigerating unit comprising a second compressor to compress a second refrigerant, a second condenser including a heat dissipation pipe to condense the second refrigerant, a second expansion valve to expand the second refrigerant, and a second evaporator to evaporate the second refrigerant, the second refrigerating unit supplying cold air to the second storage compartment, wherein the first compressor, the second compressor, and the first condenser are disposed in the machine compartment and are cooled by forcible flow of air caused by the blower fan disposed between the first compressor and the second compressor, and the heat dissipation pipe is attached to an inner surface of the outer case of the body and is cooled by natural convection of air.
