The present work deals with a low-temperature thermally driven desalination unit exploiting the HD (Humidification/Dehumidification) process. A HD desalination prototype has been designed, assembled and fully instrumented in order to monitor all physical quantities and to evaluate the performance under different operating conditions. The prototype has been experimentally investigated on a test facility established at the Bergamo University Labs. A computer code for simulating the desalination process has also been developed and it was validated by the experimental data. The modeling procedure allows to predict the HD desalination unit performance, varying seawater and air flow rates and all operating conditions.
Il presente lavoro ha per oggetto un’unità di dissalazione ad alimentazione termica a bassa temperatura, operante secondo il processo HD (Humidification-Dehumidification). Un prototipo di dissalatore HD è stato progettato, costruito e sottoposto ai primi test presso i laboratori dell’Università di Bergamo. Parallelamente all’attività sperimentale, è stato sviluppato e validato un codice di calcolo per la simulazione delle prestazioni dell’unità di dissalazione: tale codice permette di prevedere il comportamento del sistema al variare delle condizioni operative e della sorgente termica impiegata.

Abstract
The present work deals with a low-temperature thermally driven desalination unit exploiting the HD (Humidification/Dehumidification) process. A HD desalination prototype has been designed, assembled and fully instrumented in order to monitor all physical quantities and to evaluate the performance under different operating conditions. The prototype has been experimentally investigated on a test facility established at the Bergamo University Labs. A computer code for simulating the desalination process has also been developed and it was validated by the experimental data. The modeling procedure allows to predict the HD desalination unit performance, varying seawater and air flow rates and all operating conditions.File | Dimensione del file | Formato | |
