System for cooling a data center using evaporation heat of lng liquid gas

A method of cooling a data center using evaporation heat of liquefied natural gas (LNG), comprising:

• vaporizing LNG in a first main vaporizer;
• circulating a first refrigerant between a first refrigerant storage tank and the first main vaporizer;
• cooling the data center using a plurality of first unit coolers installed in a first refrigerant supply pipe;
• cooling the first refrigerant using a first water-cooled refrigerator;
• and
• circulating cooling water between the first water-cooled refrigerator and a residual gas vaporizer.

A data center cooling system, comprising:

• a liquefied natural gas (LNG) vaporization unit including a first main vaporizer;
• a first refrigerant circulation system coupled to the first main vaporizer and including a plurality of first unit coolers for cooling the data center;
• a water-cooled refrigeration unit coupled to the first refrigerant circulation system;
• and
• a cooling water circulation system coupled to the water-cooled refrigeration unit and a residual gas vaporizer of the LNG vaporization unit.
