Fluid cooling plant and refrigerant module thereof

Abstract

A fluid cooling plant to cool and liquefy a fluid, like a hydrogen, is disclosed. The fluid cooling plant comprises a first cooling stage, and a second cooling stage, connected to the first cooling source. The first cooling stage has a cold source and a heat exchanger, to cool the ambient temperature hydrogen gas. The cold source is liquid natural gas but not only, which is gasified by ambient temperature hydrogen so that the hydrogen is cooled down. The second cooling stage is made of one or more refrigerant modules, whose operation is based on a magnetocaloric material. Also disclosed is an operating method of the refrigerant modules.
