Description
Summary:This paper studies the experimental and numerical thermal performance of an evacuated tube solar collector (EVT) with a (PCM) integration at different working fluids. Two types of working fluid were used, the first working fluid is water and the second is ethylene glycol with a 30% percentage added to water. A two-dimensional numerical model is developed using ANSYS software program V.21. The results indicated that the addition of ethylene glycol with 30% percentage to the distilled water increased the evaporation temperature by 27% and improved the thermal properties. This improvement allows for an increase in the number of evacuated tubes in closed heating systems.
