Abstract :

Healthy and fresh water supply is one of the fundamental issues in different regions of the world, particularly in remote areas is dry. There are several methods for desalination of brackish waters, of which solar distillation devices can be the perfect solution for sparsely populated areas that are of sufficient intensity solar radiation. In this study, we have tried to express the necessity of providing safe drinking water, the fundamentals of performance of solar desalination dealt with the resources available. In the present study the effect of water cooling with two modes: Desalination with heat pipe and manifold (semi-active) and desalination to cooling water and heat Vlvlhhay manifold (active mode) are tested daily production was investigated. Tests in August (September) in geographical coordinates(N:35°34′,E:53°22′)is conducted. Based on the results observed The maximum rate of production of fresh water in active mode 0.43(kg / m2) per hour. As well as the daily yield semi-active mode from 1.87 (kg / m2.day) daily 2.085(kg / m2) reached in active mode.
