【 摘 要 】

This work studies the novel solar water heater using natural black rocks as the absorption material. The objective of this study is to compare the thermal performance of solar water heater between using black rocks and black copper pipes. Both options were tested at the same parameters such as 0.8 m2 collector area, angle tilted 19° and 30 litters of water tank volume. The experimental results showed that the maximum mean temperatures of solar water heater of absorption type using natural black rock system and black copper pipes system were 54.3 °C and 50.7 °C, respectively. In addition, the efficiencies of the water heater of absorption type using natural black rock system and black copper pipes system were 44.6% and 33.5%, respectively. Therefore, the water heater of absorption type using natural black rock system is another option used in the household sector to reduce the energy consumption of the country.
