Abstract

Solar stills are attractive method to produce potable water from saline sea water in large areas of the world. The productivity of water from the still increases with increasing the radiation intensity on the still surface. The use of reflector to enhance the solar radiation on the evaporation surface of the Still is promising. In the present work, an experimental investigation on the performance of solar still which is augmented by planar reflector is carried out. Two identical solar stills are designed and constructed with water surface area of 1m x O.5m ). For the purposes of comparison, a vertical mirror is supported in the east west direction on the back side of one still. Measurements of solar radiation intensity, ambient temperature, water temperature in the still and productivity are recorded in the day time. The effect of radiation enhancement on the still performance is discussed. Also, the work demonstra3ed to what extent productivity of the still can be improved.
