WIPO Patent Application WO/2023/068449
Kind Code:
A1
Abstract:
A refrigerant charging system for a reliquefaction system for a ship is disclosed. The refrigerant charging system for a reliquefaction system for a ship, according to the present invention, comprises: a reliquefaction system which is provided in a ship to reliquefy boil-off gas, generated from a storage tank having liquefied gas stored therein, by compressing the boil-off gas and performing, in a heat exchanger, heat exchange between the compressed boil-off gas and a refrigerant circulated through a refrigerant circulation line; a buffer tank in which utility N2 to be supplied to the ship is stored; a boosting compressor which is supplied with the utility N2 from the buffer tank and compresses and supplies same to the refrigerant circulation line; and a first load-up line which supplies the utility N2 from the buffer tank to the refrigerant circulation line while bypassing the boosting compressor, wherein during initial charging in a state where the reliquefaction system is stopped, the utility N2 is supplied from the buffer tank to the refrigerant circulation line through the first load-up line by a differential pressure between the refrigerant circulation line and the buffer tank, and thereby the refrigerant is charged.
