An Experimental Study to Improve the Performance of a Solar Still Using Solar Collectors

Abstract

The performance of the double-slope solar distiller is combined with two types of solar collectors (vacuum tube solar heater ETC and solar concentrator PTC). The water inside the solar distiller is heated by a heat exchanger linked with the solar heater and the concentrator. 1.4, 1.7 and LPM 2). The results showed that the high temperature of the brine water inside the distillate was obtained at the LPM 2 flow, while the productivity was 2.248, 2.774, and 4.367 liters / day, respectively, for a depth of 0.05 meters of brackish water for the three flows, respectively. The maximum thermal efficiency capacity per hour was 53%. And 51% and 64.1% for water flows of 1.4, 1.7, and LPM 2, respectively. 15.00 hours the thermal efficiency per hour was maximum when the brine temperature was maximum and the base of the tank was at 15.00 hours.
