Title:
COLD RECOVERY SYSTEM AND STARTING METHOD FOR COLD RECOVERY SYSTEM
Document Type and Number:
Japanese Patent JP2023020523
Kind Code:
A
Abstract:
To provide a cold recovery system capable of suppressing clogging of a heat exchanger at start of the cold recovery system, and a starting method for the cold recovery system.SOLUTION: A cold recovery system 1 includes: a first heat exchanger 11 transferring cold energy from liquefied gas to a cold heating medium; a cold recovery cycle 3 including a cold pump 31 provided downstream of the first heat exchanger; a second heat exchanger 14 transferring thermal energy from a heating medium to the cold heating medium flowing between the cold pump and the first heat exchanger; a gas liquid separator 5 provided between the first heat exchanger and the cold pump and separating the cold heating medium into a gas phase and a liquid phase; a liquid return line 6 for returning the liquid phase cold heating medium from between the cold pump and the second heat exchanger to the gas liquid separator; and a third heat exchanger 7 transferring cold energy of the liquefied gas to the liquid cold heating medium to be returned to the gas liquid separator via the liquid return line or the cold heating medium present in the gas liquid separator.SELECTED DRAWING: Figure 1
