Disclosed is a refrigerant charging system for a reliquefaction system of a ship. The refrigerant charging system for the reliquefaction system of the ship according to the present invention comprises: a reliquefaction system provided in the ship, a refrigerant circulation line to re-liquefy the boil-off gas by compressing the boil-off gas generated from a storage tank having a liquefied gas stored therein and performing heat exchange in a heat exchanger between the compressed boil-off gas and the refrigerant circulated through the refrigerant circulation line; a buffer tank in which common nitrogen to be supplied to the ship is stored; a booster compressor which is supplied with the common nitrogen gas from the buffer tank, and which compresses and supplies the same to the refrigerant circulation line; and a first loading line that supplies the common nitrogen gas from the buffer tank to the refrigerant circulation line while bypassing the supercharge compressor, in which the first loading line supplies the common nitrogen gas from the buffer tank to the refrigerant circulation line while bypassing the supercharge compressor during the initial charge in a state in which the reliquefaction system is stopped. The common nitrogen gas is supplied from the buffer tank to the refrigerant circulation line through the first loading line using a differential pressure between the refrigerant circulation line and the buffer tank, and thereby the refrigerant is charged.
公开一种用于船舶的再液化系统的制冷剂充注系统。根据本发明的用于船舶的再液化系统的制冷剂充注系统包括:再液化系统,设置于船舶中,以通过压缩从具有存储于其中的液化气体的存储罐产生的蒸发气体且在热交换器中执行经压缩蒸发气体与通过制冷剂循环管线循环的制冷剂之间的热交换来再液化蒸发气体;缓冲罐,待供应到船舶的公用氮气存储于其中;增压压缩器,供应有来自缓冲罐的公用氮气,且将其压缩且供应到制冷剂循环管线;以及第一加载管线,将来自缓冲罐的公用氮气供应到制冷剂循环管线同时绕过增压压缩器,其中在再液化系统停止的状态下进行初始充注期间,公用氮气利用制冷剂循环管线与缓冲罐之间的差压通过第一加载管线从缓冲罐供应到制冷剂循环管线,且由此充注制冷剂。
