This paper deals with an experimental investigation of the effect of the working fluid inventory on the performance of the gravity assisted solar heat pipe. Measurements of solar flux and the temperature in different positions over the heat pipe have permitted us to evaluate the performance of the system for different working conditions. Results prove that the optimum performance is observed when the 2/3 of evaporator volume is filled with methanol.
► Develop a prototype of a solar domestic hot water system using a gravity assisted heat pipe. ► Investigate of the energy behavior of the heat pipe. ► Different fill charges have been experimentally tested. ► Investigate the influence of the liquid fill charge on the thermal performance. ► Predict the maximum performance.
