The present disclosure relates to a refrigerator, and more particularly, to a refrigerator including one or more modules having a plurality of rooms. An embodiment of the present disclosure may provide a refrigerator including a plurality of refrigerator modules, wherein the refrigerator modules include: a cabinet forming an outer shape and having a plurality of storage chambers therein; doors provided in the cabinet and provided for each storage chamber; a radiant cooling plate which forms the rear wall of the storage chambers, and is provided to block the communication of air between the inner portions of the storage chambers and cool the inner portions of the storage chambers through radiant cooling; a refrigerant pipe flow path located at the rear side of the radiant cooling plate to exchange heat with the radiant cooling plate; and a machine room which discharges the refrigerant to the refrigerant pipe flow path and sucks the refrigerant having exchanged heat with the radiant cooling plate.

A hybrid shellfish cooling system employs both DC and AC cooling units that use both solar power and AC electrical supply as energy sources. As temperature control and uniform temperature distribution in the cooling system are critical factors in reducing vibrio growth on raw oysters and reducing energy consumption, the hybrid shellfish cooling system is equipped with a specially configured divider that optimizes airflow through the cooling system interior cabinet to achieve uniform temperature distribution in six individual internal compartments inside of the cooling system. Test results indicated that an average of 130 min. cooling was required to reach the suggested oyster temperatures of 7.2° C. and meet the cooling time requirement (i.e., 10 h or less). Airflow is further optimized via fan location and airflow direction, whereby a circulation fan located on the lower part of the 12-volt DC section with an air supply from the 12-volt DC section to the 110-volt AC section provides the optimal condition to achieve relatively uniform temperature distribution.

Cooling device 1, in particular a freezer 2, having a closable cooling space 3, an electrically operated cooling circuit, and preferably a cold storage pack 4, wherein the at least one closable cooling space 3 and the cold storage pack 4 can be cooled by the electrically operated cooling circuit. The cooling device has a power distributor 5 for distributing electrical power of at least one regenerative power source 6 to an electrically operated cooling circuit of the cooling device 1 and to at least one further electricity consuming device 7. In addition, the power distributor 5 has a control system with a computing unit 23, a memory 24 and priority logic. The priority logic is used to preferentially supply the electrically operated cooling circuit of the cooling device 1 with electricity if there is a lack of electrical power of the at least one regenerative power source 6.
