Expandable type refrigerator

摘要

An expandable type refrigerator which is capable of coupling a plurality of refrigerating units or freezing units which each have an independent operational cycles and a predetermined size and is easily expanded at the site of refrigerator installation by coupling a plurality of the refrigerating units or freezing units, wherein each refrigerating unit or freezing unit is capable of controlling one micro-controller by using one power cord. The refrigerator includes more than at least two refrigerating units (or two freezing units) each of which is operable with a different operational cycle and which refrigerating units are coupled to each other at an installation site, a coupling apparatus for coupling the refrigerating units, one external power cord for supplying an electric power to the refrigerating units (or the freezing units), and an operational cycle controller for independently controlling the operational cycles of the refrigerating units (or the freezing units).
