Title:
COOLING SYSTEM FOR COOLING PLURALITY OF AUXILIARY REFRIGERANTS BY USING LNG COLD ENERGY
Document Type and Number:
WIPO Patent Application WO/2023/033415
Kind Code:
A1
Abstract:
A cooling system for cooling a plurality of auxiliary refrigerants by using LNG cold energy, according to an embodiment of the present invention, comprises: a first main heat exchanger for allowing heat exchange between a main refrigerant and a pre-set predetermined amount of liquefied gas discharged per unit time from a liquefied gas storage tank, so as to cool a main refrigerated warehouse; a main refrigerant pipe which is connected to the main refrigerated warehouse, and in which the main refrigerant passing through the first main heat exchanger flows; N (N is a natural number greater than or equal to 2) auxiliary heat exchangers for allowing sequential heat exchange between N auxiliary refrigerants and the main refrigerant so as to cool N auxiliary refrigerated warehouses; and N auxiliary refrigerant pipes which are respectively connected to the N auxiliary refrigerated warehouses and in which the N auxiliary refrigerants respectively flow.
