摘要：

A design of a double-condensing chamber solar still (DCS) is described. In this design the vapour is formed in the first chamber after the water is heated by solar radiation. Then the vapour is allowed to move into the second chamber through a vent provided at the top of the partition wall of a solar still. The transferred vapour is condensed on the metallic condensing surface behind the partition wall. The vapour is also condensed on the inner surface of the double glass cover of a solar still. Experiments were carried out during September 1995 to August 1996. The daily yields of the DCS and a conventional solar still are compared on the basis of experimental results. It has been observed that there is significant enhancement in daily output due to a maximum vapour pressure difference between the two condensing chambers on a clear day.
