Air-Heating Solar Collectors for Humidification-Dehumidification Desalination Systems

Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products. However, in the context of a humidification-dehumidification (HDH) desalination cycle, air heating accounts for advantages in cycle performance. Solar collectors can be over 40% of an air-heated HDH system’s cost; thus, design optimization is crucial. Be...

Solar Power Technologies for Desalination

Throughout the world, there are regions of vast extent that have many favorable features, but whose development is principally limited by the lack of fresh water. In arid areas where large-scale development has already occurred, e.g. parts of the Middle East and North Africa, the extraction of fresh water via desalination plants requires very large energy consumption. This motivates the develop...

An experimental study of solar thermal vacuum membrane distillation desalination

An experimental desalination system coupling a vacuum membrane distillation (VMD) unit and a vacuum tube solar heat collection (SHC) unit was developed and tested. The parametric sensitivity of the VMD unit performance was investigated first using an electric heater as the heat source, and then the whole system was examined using solar heat. It was revealed that hot feed temperatures higher tha...
