Abstract—In this paper a direct heated solar desalination system
was designed, his system can raise the fresh water production II. THE DIRECT HEATED SOLAR DESALINATION
through avoiding the heat loss between collector and desalination EXPERIMENTAL DEVICE
and increasing the first stage evaporation temperature. The
effects of solar radiation on the highest seawater temperature
and fresh water production are researched. The results indicated
that the system has a high fresh water production and a shorter
time of reaching steady, and it is suited to solar radiation
instability.
Keywords- desalination; solar energy; flash; multi effect
distillation
I. INTRODUCTION
With economic development in recent years, the use of
fresh water is increased sharply, so to explore fresh water
resources became an imperative duty. In coastal areas,
desalination technology is an effective way to solve the short of
fresh water. In the past few decades, a lot of desalination
methods were invented. In the latter half of the twentieth
century, multi-stage flash (MSF), multi-effect distillation
(MED) and reverse osmosis (RO) and other metho
