Abstract

There has been a shift in our concern for energy towards renewable energy sources as a result of the increasing demand for energy and the decreasing supply of fossil fuels. Solar energy is, without a shadow of a doubt, the most environmentally friendly and beneficial alternative among all of the other sources that are now available. In today's world, many people harvest energy from the sun using a variety of various kinds of solar collectors. It has been discovered that the efficiency of the solar collector is reliant on the properties of the working fluid, which is responsible for the collection of solar energy in solar collectors. In this study, the experimental findings of using deionized water as the working fluid for heat pipe evacuated tube solar collectors are presented. During the course of the experiment, a solar collector, a closed working fluid system, and measurement devices will be utilized (flow meter, thermocouples, temperature meter and digital solar power meter). The results of the present work can be used efficiently to improve the perfomance of solar collector in the place of study ( Babylon City ) in Iraq. This will save the energy and make the work of the collector better and increase its efficiency. From the another hand it fill the gap in the experimental studies related to ETSC in the middle east general and Iraq specially. When the solar irradiance was approximately 494 W/m² , the solar collector had a maximum temperature differential of 15.5 oC between its outlet and its inlet. The average energy efficiency reached was 67.3%.
