Patent ID: 7246504

Claim:
A method for manufacturing a cooling storage unit, comprising: using box selecting means to select a thermally insulated box from a group of thermally insulating boxes, said thermally insulated box to have combined therewith at least one cooling unit, each of said at least one cooling unit including (i) a compressor, (ii) a condenser, (iii) an expansion mechanism, (iv) an evaporator, (v) refrigerant piping, and (vi) refrigerant, with said compressor, condenser, expansion mechanism and evaporator being connected via said refrigerant piping to define a circuit containing said refrigerant, and with said expansion mechanism having an intermediary characteristic flow rate between a flow rate suitable for refrigerating use and a flow rate suitable for freezing use; transporting said thermally insulated box to a cooling storage unit installation site; transporting said at least one cooling unit to said cooling storage unit installation site; and combining said thermally insulated box with said at least one cooling unit.
