Title:
REFRIGERANT CYCLE PRESSURE CONTROL SYSTEM FOR RELIQUEFACTION SYSTEM FOR SHIP
Document Type and Number:
WIPO Patent Application WO/2022/158736
Kind Code:
A1
Abstract:
A refrigerant cycle pressure control system for a reliquefaction system for a ship is disclosed. A refrigerant cycle pressure control system for a reliquefaction system for a ship, of the present invention, comprises: a heat exchanger provided in the reliquefaction system of a ship and receives boil-off gas from a storage tank to cool same; a refrigerant cycle including a refrigerant circulation line through which the refrigerant for cooling the boil-off gas in the heat exchanger circulates, a refrigerant compressor which is provided in the refrigerant circulation line and compresses the refrigerant which cools the boil-off gas in the heat exchanger and is discharged therefrom, and an expander which expands and cools the refrigerant cooled through the heat exchanger after being compressed by the refrigerant compressor, and supplies same as the refrigerant of the heat exchanger; an inventory tank for storing the refrigerant to be filled in the refrigerant cycle; a refrigerant supply line which is connected from the inventory tank to the front end of the refrigerant compressor to replenish the refrigerant in the refrigerant cycle; a refrigerant discharge line which is connected to the inventory tank from the rear end of the refrigerant compressor to discharge the refrigerant of the refrigerant cycle to the inventory tank; and a pressure control line which branches from the refrigerant discharge line, wherein the refrigerant cycle can be reduced in pressure by discharging the refrigerant of the refrigerant cycle through the refrigerant discharge line or the pressure control line.
