  • an absorption heat pump is used as the chemical heat store.
  • external heat source can serve sea water.
  • the sea water is concentrated in a flash evaporation system.
  • thermodynamic cycle of the sorption heat pump can be coupled with the solar-heated desalination process in an advantageous manner in terms of process technology.
  • the solar energy is used for the desorption and the condensate heat to be removed from the heat pump maintains the desalination process which, in the absence of a solar energy supply, is supplied with the absorption heat released by metered combination of the working materials.
  • the system size of the solar system, the flash evaporation system and the transport lines from / to the sea to be installed can be significantly reduced compared to conventional systems. Furthermore, the installation is used much better.
  • the heating of the heat pump evaporator at a low temperature level required for the heat pump / heat storage discharge can be carried out with sea water, ambient air and / or the waste brine which is still warm.
  • the V. ' är epumpen effect thus used allows much more than the heat obtained from the solar system to be made available for the desalination process

  • valve 3 can be closed after the desorption process, as a result of which the absorption heat released during the reaction reversal can be stored without loss by storing the reactants separately.
  • the condenser / evaporator 2 of the sorption heat pump must be supplied with heat to evaporate the volatile component.
  • This heat can be taken from a secondary flow of sea water via valve 8, the ambient air and / or the residual brine 16 to be removed.
  • sea water is selected for this purpose, which, after passing through the condenser / evaporator 2, is discharged via valve 14, with valve 13 closed.

Abstract

Dans un procédé de dessalement en continu de l'eau de mer, celle-ci est concentrée en utilisant l'énergie solaire pour obtenir de l'eau douce. Durant les périodes où le rayonnement solaire est suffisant, un accumulateur chimique de chaleur (1, 2) est chargé. Cet accumulateur est déchargé durant les périodes sans soleil et durant celles où le rayonnement est insuffisant, avec utilisation d'une source de chaleur extérieure à température inférieure. La chaleur dégagée lors de la charge et de la décharge de l'accumulateur chimique est utilisée pour la concentration de l'eau de mer, de préférence au moyen d'une installation (12) d'évaporation par détente.
