The augmentation of distillate yield by using concentrator coupled solar still with phase change material
In order to augment the efficiency and distillate yield in the concentrator-coupled hemispherical basin solar still, a phase change material (PCM) was added. Two modes of operation have been studied experimentally, (1) single-slope solar still without the PCM effect, and (2) single-slope solar still with the PCM effect. The temperature of water (T-w), temperature of PCM (T-PCM), air temperature (L-air), inner cover temperature (T) and outer cover temperature (T,) were measured. Experimental results indicate that the effect of thermal storage in the concentrator-coupled hemispherical basin solar still increases the productivity by 26%. It was concluded that the productivity greatly increased due to the still integrated with PCM. (C) 2013 Elsevier B.V. All rights reserved.
