Experimental investigation on single basin tilted wick solar still integrated with flat plate collector

Single basin solar still (SBSS) has low productivity in this experimental research, some techniques have been employed to solve this problem, these techniques consist of using a flat plate collector. The main aim of this research was to make efficient use of the flat plate collector (FPC) to increase solar still productivity, and it works as a hybrid device. The model solar water heater for the flat plat collector (FPC) was coupled with a solar still, and the tests were repeated in 3 to 5 winter days, and the results were measured in the same way for each day. The results revealed that the productivity of the still increased 87 % when coupled with one, and decreased 20 % and 50 % when coupled with two and three flat plate collectors in southern Algeria, respectively.

Abstract In this communication, characteristic equation for single-slope solar still augmented with N alike parabolic concentrator integrated evacuated tubular collectors has been developed which is also valid for N alike evacuated tubular collectors integrated single-slope solar distiller unit as well as passive single-slope solar distiller unit. The developed equation is similar in the form to Hottel-Whillier-Bliss equation which was developed for flat plate collector. The analytical equation development for the proposed system involves the writing of equations for its different components on the ground of equating net energy input to net energy output. The results obtained for the proposed system have been compared with the results of N alike evacuated tubular collectors integrated single-slope solar distiller unit and passive single-slope solar distiller unit. It has been concluded that the mean value of instantaneous efficiency for N alike parabolic concentrator integrated evacuated tubular collectors is higher by 42.86% and 50.82%; daily generation of freshwater is higher by 49.73% and 74.34%; and daily exergy is higher by 78.71% and 93.35% than the corresponding values for N alike evacuated tubular collector integrated single-slope solar distiller unit and passive single-slope solar distiller unit for the same basin area in that order.
