摘要:
Cet appareil (3A, 3B) est destiné à l'échange de chaleur entre au moins un premier fluide disponible à une température voisine de la température ambiante et au moins un second fluide disponible à une température cryogénique inférieure à -20°C. Il comprend des moyens pour faire circuler le premier fluide de façon globablement centripète par rapport à un axe central général (X-X) de l'appareil (3), à partir d'une entrée radialement extérieure (17) de l'appareil, et des moyens pour faire circuler le second fluide de façon globalement centrifuge par rapport audit axe central, à partir d'une entrée radialement intérieure (18) de l'appareil. Application aux régénérateurs et échangeurs de refroidissement, et éventuellement d'épuration simultanée, d'air atmosphérique à distiller.

The present invention relates to a dehumidification system and method and, in particular, to a system and method for controlling the humidity of air in a process or location using a desiccant-coated fluid-air heat exchanger. The desiccant material adsorbs water at or above ambient temperatures during an adsorption cycle, and the resultant air stream is of a reduced humidity compared with the humidity of the supply air. The desiccant material may then be dried during a regeneration cycle through addition of heating fluid through the heat exchanger, driving water back into the vapor state with addition of latent energy of vaporization. The desiccant material may be cooled, during the adsorption cycle, through addition of cooling fluid through the heat exchanger to maintain the temperature within a range sufficient for water vapor to be removed from the stream of air.
摘要:
Heat exchange apparatus (24, 80) includes first heat transfer tubes (50), contained within an enclosure (43) and coupled to receive a first fluid heated by an energy source (22, 36). Second heat transfer tubes (52) are interleaved with the first heat transfer tubes within the enclosure so as to heat a second fluid contained in the second heat transfer tubes by transfer of heat from the first fluid, and are coupled to output the heated second fluid to drive target equipment (30). A heat storage medium (48) fills the enclosure.
