Abstract: A refrigerator comprising a main body which is formed with three or more storage compartments and a cooling unit having a plurality of evaporators corresponding to the respective storage compartments, the cooling unit comprising a refrigerant supply pipe to supply a refrigerant to the plurality of evaporators; a plurality of refrigerant branch pipes which are branched from the refrigerant supply pipe to mount the evaporators thereto, and to at least one of which the plurality of evaporators are connected in series; and a refrigerant connection pipe to connect an outlet of one of the plurality of refrigerant branch pipes and an inlet of the other one of the plurality of refrigerant branch pipes.

Abstract: A refrigerator includes a main body cabinet having a first storage room and a second storage room to be divided with the first storage room and respectively cooled, an evaporator having a first evaporating part disposed at the main body cabinet and cooling the first storage room, a second evaporating part disposed at the main body cabinet to be apart from the first evaporating part and cooling the second storage room, and a refrigerant moving pipe connecting the first and second evaporating parts, and a duct guiding cooling air generated by the first and second evaporating parts to the first and second storage rooms to respectively cool the first and second storage rooms, the first and second evaporating parts and the refrigerant moving pipe are formed with one evaporating pipe. The refrigerator forms integrally an evaporator for cooling a first storage room and a second storage room respectively.
