摘要：

This paper presents a modification of parabolic concentrator (PC) - solar still with continuous water circulation using a storage tank to enhance the productivity. Four modes of operation were studied experimentally: (i) PC-solar still without top cover cooling; (ii) PC-solar still with top cover cooling, PC-solar still integrated with phase change material (PCM) without top cover cooling and PC-solar still integrated PCM with cooling. The experiments were carried out for the cooling water flow rates of 40 ml/min; 50 ml/min, 60 ml/min, 80 ml/min and 100 ml/min. Diurnal variations of water temperature (T-w), ambient air temperature (T-a), top cover temperature (T-oc) and production rate are measured with frequent time intervals. Water cooling was not cost effective, but adding PCM was. (C) 2015 Elsevier Ltd. All rights reserved.
