Disclosed herein is a refrigerant charging system for a reliquefaction system for ships. The refrigerant charging system includes: a reliquefaction system provided to a ship and reliquefying boil-off gas generated in a liquefied gas storage tank by compressing the boil-off gas and subjecting the compressed boil-off gas to heat exchange with refrigerant supplied to a heat exchanger while circulating along a refrigerant circulation line; a buffer tank storing utility N2 to be supplied to the ship; a booster compressor receiving the utility N2 from the buffer tank, compressing the received utility N2, and supplying the compressed utility N2 to the refrigerant circulation line; and a first load-up line along which the utility N2 is supplied from the buffer tank to the refrigerant circulation line without passing through the booster compressor, wherein, upon initial charging in a non-operation state of the reliquefaction system, the refrigerant circulation line is charged with refrigerant by supplying the utility N2 from the buffer tank to the refrigerant circulation line along the first load-up line by a pressure differential between the refrigerant circulation line and the buffer tank.
