Disclosed is a liquefied gas cooling system. According to one embodiment of the present invention, the liquefied gas cooling system comprises: a refrigerant compression unit which compresses a refrigerant with a medium temperature and a low pressure, and converts the refrigerant into one with a high temperature and a high pressure; a first heat exchange unit which makes the compressed refrigerant exchange heat with cooling water, and converts the refrigerant into one having a medium temperature and a high pressure; a second heat exchange unit which reduces the temperature of the refrigerant which has passed through the first heat exchange unit; an expander which expands the refrigerant, which has passed through the second heat exchange unit, and converts the refrigerant into one having a low temperature and a low pressure; a liquefied gas cooling unit which performs heat exchange between the expanded refrigerant and the liquefied gas supplied from a storage tank, cools the liquefied gas, and converts the refrigerant into one having a medium temperature and a low pressure; a refrigerant circulation supply line which circulates and supplies the refrigerant which has passed through the refrigerant compression unit, the first heat exchange unit, the second heat exchange unit, the expander, and the liquefied gas cooling unit, towards the refrigerant compression unit side through the second heat exchange unit; a cooling water circulation supply line which circulates and supplies the cooling water towards the first heat exchange unit side; and a cooling water cooling unit which is placed on a front end of the first heat exchange unit on a cooling water circulation supply line to make the cooling water supplied to the first heat exchange unit exchange heat with the refrigerant used in an inert gas generation unit so as to reduce the temperature of the cooling water. The present invention aims to provide the liquefied gas cooling system which is able to reduce the evaporated gas generated in the storage tank.
