摘要: Abstract Destructing thermal stratification of water storage tank and effect on solar collector performance was investigated experimentally. First experiment performed using conventional thermosyphon flow water. In the second experiment, without discharging hot previous day, continued. Third fourth experiments were started with similar condition to first case. However, in third case during tank’s mixed a circulating pump case, fresh replaced at three different times same amount from Results indicated lowering temperature lower layers would enhance performance. Collector accordingly best worst; discharge, conventional, circulation, initially charged recharge. For example, 16:00, collector’s efficiencies for three-time normal, destruction 52.9%, 38.3%, 32%, respectively. Further, 17:00, efficiency discharge 36% while nearly zero other obtained. addition, heat absorption study, theoretical results compared experimental results.
