Experimental study on thermosyphon solar water heater in Bahrain

摘要

The thermal performance of the thermosyphon water heater unit was analyzed to show its applicability in Bahrain, suing data of several sunny, cloudy and hazy in winter. The performance of this unit was studied under various maximum daily solar intensities, ranging from 1,2 and 3 on a cloudy day, upto 695 W/m~2 on a sunny day, with the daily outside temperature ranges between 25-19 deg. C. The results shown that the system has an average efficiency of 38/100 with storage tank temperature above 50 deg. C. these results show that this system is quite suitable for application in Bahrain weather weather conditions.
