“…A simple [24,25,26,27] air-heated cycle is one in which air is heated, humidified, and dehumidified. Current simulations have found that the GOR for this cycle is very low (GOR<1, only slightly better than a solar still).…”

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.

“…It is worth mentioning that the high amount of fresh water production in studies [29,30] is a result of using auxiliary electric heaters for water heating. In these studies, since the collector area was reduced due to the use of electric heaters, the daily rate of production per total solar absorption area were significantly higher.…”

“…This is because most of the latent heat of condensation of water vapor is lost at the cover of the still and all the main processes of heating, evaporation and condensation take place within a single component [15,16]. HDH process, however, separates the humidification and dehumidification processes into distinct processes in different components [17][18][19] where improvement in each process can take place. On the other hand, when PV panel is used to generate electricity, heat is dissipated together with the electrical energy produced [20].…”
