Abstract
This paper reports experimental studies on the performance of a natural circulation solar water heater considering the weather condition of a city in north of Iran. The tests are done on clear and partly cloudy days. The variations of storage tank temperature due to consumption from the tank, daily consumption influence on the solar water heater efficiency, and on the input temperature of the collector are studied and the delivered daily useful energy has been obtained. The results show that by withdrawing from storage tank, the
system as well as its collector efficiency will increase. Considering the value of the coefficient FRUL and τα, which are obtained experimentally as 6.03 and 0.83 respectively, average.
monthly total load that is covered by this solar water heating system is estimated.
