Method for refrigerating a heat exchange panel
View Patent ↗Desalination apparatus based on porous restraint panels fabricated from a number of different layers of metal, thermoplastic, or other substances are used as sophisticated heat exchangers to control the growth of gas hydrate. The gas hydrate is produced after infusion of liquid hydrate-forming material into water to be treated, which liquid hydrate-forming material can also be used to carry out all the refrigeration necessary to cool seawater to near the point of hydrate formation and to cool the porous restraint panels. Hydrate forms on and dissociates through the porous restraints. The composite restraint panels can also be used in gaseous atmospheres where, for instance, it is desired to remove dissolved water.
1. A method for refrigerating a heat exchange panel, comprising:
filling a series of first sub-galleries extending internally throughout the heat exchange panel with liquid refrigerant; and
vaporizing the liquid refrigerant across microporous regions of a refrigerant distribution member into a series of second sub-galleries extending internally throughout the heat exchange panel.
2. A method for refrigerating a heat exchange panel, comprising:
filling a series of first sub-galleries extending internally throughout the heat exchange panel with liquid refrigerant; and
vaporizing the liquid refrigerant across very-tiny-hole-containing regions of a refrigerant distribution member into a series of second sub-galleries extending internally throughout the heat exchange panel, the very-tiny-hole-containing regions having perforations or openings on the order of about thirty to about eighty microns.
3. A method for refrigerating a heat exchange panel, comprising:
filling a series of first sub-galleries extending internally throughout the heat exchange panel with liquid refrigerant; and
vaporizing the liquid refrigerant across a refrigerant distribution member into a series of second sub-galleries extending internally throughout the heat exchange panel by lowering vapor pressure in the first sub-galleries to below a vapor pressure of a gas/liquid transformation point of said refrigerant.
