<p><P>PROBLEM TO BE SOLVED: To provide a technology reduced in energy consumption and a heat source capacity required for air-conditioning more than before. <P>SOLUTION: The cooling system is provided with: a cooling unit set inside a refrigeration warehouse or a freezing warehouse; a condensing unit set outside the warehouse and connected to the cooling unit via a pipe; a supercooling heat exchanger set to the refrigerant outgoing pipe wherein a condensed refrigerant flows toward the cooling unit and supercooling the condensed refrigerant; a cooling column connected to the supercooling heat exchanger via a pipe; a defrosting medium outgoing pipe connected to a supercooling medium return pipe wherein the supercooling medium heat-exchanged in the supercooling heat exchanger flows toward the cooling column and allowing the heat-exchanged supercooling medium to flow toward the cooling unit as a defrosting medium; a defrosting section set in the cooling unit and defrosting the cooling unit by the defrosting medium flowing in the defrosting medium outgoing pipe; and a defrost medium return pipe connecting the cooling unit to the cooling column, and allowing the defrost medium after defrosting the cooling unit to flow toward the cooling column. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
