Abstract

The efficiency of a household thermostat solar water heater model with two flat panel collectors and a double-glazed storage tank of 200 liters capacity was investigated experimentally. Water and glycol (antifreeze) are used as operating fluid in the water heater to be transformed into thermosyphon with free movement and increase the temperature of consumed water. Water is not discharged during the test period. Flow temperatures of collector input and output, city water temperature, water temperatures at different points in the reservoir and ambient temperature for sunny days in the autumn in Tehran. Measurement and flow rate of the thermosyphon, thermal energy of the water consumed and total water efficiency The aforementioned heater has been calculated and the corresponding graphs are given over time. The results show that the highest water temperature is 60 °C on sunny days and 50 °C on cloudy days. The overall efficiency of the thermostat solar thermal heater will be around 45درصد during the month of November 1396. The highest photovoltaic panel efficiency in the sunny days is 13.5% in the autumn and 11.6% in the cloudy days, which is due to the decrease in efficiency compared to the ideal conditions. The surface temperature of the panel is high.
