“…Solar photovolatics can be used to operate reverse osmosis units for small scale applications in these countries. But it may not be feasible due to the high cost of PV modules and maintenance of RO systems [2]. A much simpler option is to use the solar energy as a source of thermal energy.…”

Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the system performance. In this paper, we analyze the thermodynamic performance of various HDH cycles by way of a theoretical cycle analysis. In addition, we propose novel high-performance variations on those cycles. These high-performance cycles include multi-extraction, multi-pressure and thermal vapor compression cycles. It is predicted that the systems based on these novel cycles will have gained-output ratio in excess of 7 and will outperform existing HDH systems.

“…Desalination of sea water can be carried out by two broad classes of methods, viz., thermal or conventional route and reverse osmosis (RO). The costs of thermal desalination plants are high as it consumes more energy as compared to reverse osmosis [13]. In coastal locations, where fresh water shortage is compounded by non availability or unreliability of grid power, reverse osmosis plants driven by renewable energies such as solar or wind appear to be a viable option.…”

“…Ghobeity and Mitsos [6] solved a formal optimization problem to minimize cost associated with power consumed by an RO plant if the electricity tariff is time dependent. There are studies on battery-less operation of RO units based on field trials [13,8]. But attempts towards optimal operating strategy of RO unit (powered by solar power without batteries) based on solving a formal optimization problem are scarce in literature.…”

“…As result, parabolic trough collectors were found to be the most competitive option over other thermal collectors and equivalent PV-driven system. Manolakos et al [20][21][22][23] designed and tested a small stand-alone system using a scroll expander; simulations of the latter were carried out by Schuster et al [24] who put in evidence the influence of the collector slope on the system productivity.…”
