ABSTRACT

 

An experimental setup is built in order to evaluate the distillate yield for a compound parabolic Concentrator-Concentric Tubular Solar Still (CP-CTSS). A CPC with a ‘V’ groove at the bottom of the reflector to reduce the gap losses is designed with half acceptance angle of 23.5°.  A 2 m long transparent concentric tube and rectangular absorber trough in the same length has been fabricated.  The rectangular absorber basin placed inside the tubular arrangement and filled with saline water for appropriate height. The entire experimental device is operated with cold water flow over the inner tubular covers (10 ml/min). The heat extracted water from the outlet is linked with single slope solar still. The solar radiation on the solar still is also discussed here.
