【 摘 要 】

Daily useful energy was studied on different daily solar irradiance, which is important to the coefficient of thermal performance(CTP) of domestic solar water heater. The numerical simulation of 8 hours thermal performance experimental was carried out by Fluent, and the thermal energy equation was obtained by least-squares fitting method, the influence between daily solar irradiance and daily useful energy was analyzed quantitatively, The feasibility of the equation was verified. The accuracy of the test results could be increased by the application of the equation.
