“…We can mention also the work of Ben Slama, R [9] concerning the coupling of a refrigerator and water heater in which the water temperature reached 60°C and the heating floor reached 30°C in 24 hours. Ben Halima, H et al [10] studied the coupling of a solar still and heat pump. They found that the production of fresh water of the new still improved comparing with ordinary still witch lead to the importance of desalination using heat pumps.…”

With the aim of saving energy and to reduce global warming effect, our work focuses on the valorization of the waste heat evacuated by the condenser of a refrigeration machine (air-conditioner) for the desalination of sea water. In this paper, the conception of a new system combining airconditioning and desalination is realized. The modelling of the heat exchanges of each part of the system is realized. To improve the performance of the system, various experimental tests are represented and discussed. Comparison between simulation and experimental results shows a good agreement and present a courageous motive for the system application.

This article presents a theoretical study and experimental validation of a new solar bubbler basin using as a humidifier in humidification–dehumidification desalination system. The prototype consists mainly of a simple solar basin, filled with water, through which air is forced to travel upwards in form of bubbles. A detailed mass and heat transfer analysis was elaborated to model the dynamic behavior of the new humidifier. It is through a comparison with the experimental data that the validity of the proposed model was tested. The simulation results have revealed that the humidification efficiency and the amount of evaporated water can reach 98% and 6 kg m−2 day−1, during the spring equinox. The effects of some operational parameters (water depth, inlet air temperature, and flow rate) were investigated. It was found that the inlet air temperature and flow rate have a significant effect on the water content difference in the humidifier. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 518–526, 2019
