Abstract

In the present work, a solar desalination-heating system with heat recovery is proposed. The system includes a solar collector, humidifier, storage tank and a water-cooled condenser. The thermal design of a typical unit is presented. Both latent heat of the condensed vapour and the sensible heat of the circulating air are recovered, and added as a sensible heat to the inlet water in the condenser. The system is simple in construction, operation and control. Therefore, it is a suitable option for remote areas where only the ground water, or wells are available. The thermal performance of the system is also studied under different operating conditions. Results have shown that this system is highly recommended for practical application.
