A device for regasification of LNG, and cogeneration of fresh water and dry air, having a casing hermetically sealed from the exterior withstanding vacuum conditions, and containing a working fluid in its liquid and gaseous phases; the casing is traversed by t a cryogenic tube through which LNG is fed and regasified natural gas is collected via the other end. The external surface of the cryogenic tube condenses the gaseous working fluid, releasing energy, and evaporative condenser tubes located outside the casing, with the external condensing surface in contact with damp air, and the air vapor contained in the damp air condenses thereupon, generating cold fresh water and releasing energy to the working fluid in its liquid phase which flows through the evaporative condenser and which evaporates, generating a gaseous phase working fluid, which exits through the evaporative condenser and is directed into the casing for the condensation

A cooling system includes a coolant transmitter that transmits coolant at a pressure greater than atmospheric pressure. The cooling system also includes an evaporation vessel at atmospheric pressure. The evaporation vessel can contain an amount of coolant at the boiling point of the coolant. The cooling system also includes a pressure reducer fluidically coupled to the coolant transmitter and the evaporation vessel. The pressure reducer can include an orifice. The cooling system is configured such that heat is transferred from the coolant in the coolant transmitter to the coolant contained in the evaporation vessel. An exit stream conduit can fluidically couple the coolant transmitter and the pressure reducer, with the exit stream conduit diverting a portion of the coolant from the coolant transmitter to the evaporation vessel.

A thermal management system includes a closed-circuit refrigeration system (CCRS) that includes a vapor cycle system (VCS). The VCS includes a receiver configured to store a refrigerant fluid; a liquid separator; a compressor; a condenser; at least one evaporator configured to extract heat from at least one heat load that is in thermal conductive or convective contact with the evaporator; and a thermal energy storage (TES) that stores a phase change material.

A method of preparing and storing a free-flowing frozen supplementary product, including preparing a supplementary composition for freezing, dripping the supplementary composition into a freezing chamber, freezing the dripped supplementary composition into beads, and transporting the frozen beads by conveyor belt out of the freezing chamber.

A heat transfer device includes a storage chamber, a coolant housed within the storage chamber, a cooling chamber, one or more heat transfer components, a fluid passage between the storage chamber and the cooling chamber, and a barrier element. The one or more heat transfer components facilitate heat transfer from a heat source outside of the cooling chamber to the cooling chamber. The barrier element may have (i) a closed configuration, and (ii) an open configuration in which the barrier element is configured to allow the coolant in the storage chamber to flow from the storage chamber into the cooling chamber. The barrier element may reconfigure from the closed configuration to the open configuration in response to a trigger condition, such as the coolant housed within the storage chamber reaching a trigger temperature and/or the initial pressure of the coolant housed within the storage chamber reaching a trigger pressure.
