In this paper, experimental evaluation and mathematical modeling of single slope hybrid solar still integrated with an air compressor at a different air injection rate within water basin. A compressor unit is used to inject air with different flow rate viz. 0.01, 0.03, 0.05 and 0.06 Kg/s in sea water within the basin area of hybrid solar still. Compressed air injection in water influences the performance parameters such as the temperatures and different modes of heat transfer rate. Rate of convective heat transfer between water and air reaches 2.2 W / m² ° C, between air and glass the convective heat coefficient equal 0.6 W/ m² ° C. The temperature difference between water and inner glass surface, with an addition of dry air inside the basin will enhance cumulative productivity (Pcu) of the hybrid single slope solar still and recorded 16 L/m².day. A comparative study of convective, evaporative heat transfer coefficients also has been reported.
