Abstract
The main objective of this study is to conduct a controlled thermal investigation of a small Parabolic Trough Concentrator (PTC) under a real climatic conditions for El-Oued region on 16/03/2018, where the water was adopted as a heat transfer fluid. One-dimensional and transient energy balance equations have been analyzed, simplified and then programmed with the Matlab code. What distinguishes this study is the precise tracking of all heat coefficients that would give an accurate representation of the thermal behavior of the studied device. The average optical efficiency of the device has reached 78.55 %, the average value of the thermal efficiency has reached 74.30 %, while the average value of the overall coefficient of the thermal loss is 5.96 W.m-2.°C-1. Water steam has been formed under the effect of practical conditions between 10:20 and 11:50. The results obtained in this study encouraged the research team to start manufacturing this device with the dimensions mentioned in this paper, in order to direct this prototype setup to conduct scientific experiments will be in the field of solar cooling, desalination, water heating and other areas that serve the society welfare and maintain the environment integrity.
Highlights
Solar energy is the heat and light coming from the sun, which human has used in his service since ancient times by using the technology traditional means that has developed to facilitate the life [1,2,3]
Pure water was chosen as a heat transfer fluid
The heat transfer fluid temperature, which has a maximum value of 110.05 °C and a minimum value of 11.05 °C;
Summary
Solar energy is the heat and light coming from the sun, which human has used in his service since ancient times by using the technology traditional means that has developed to facilitate the life [1,2,3]. It can be used to cook food in solar furnaces [19, 20], where these furnaces collect sunlight at a central point and turn sunlight into a heat. It is used for desalination [21, 22], drying [23,24,25], electricity production [26,27,28,29], air conditioning [30,31,32,33] and process heat applications [34,35,36]. All these areas of the solar energy will help solve global energy crises, save money and reduce bills because the sun is a free and clean source of energy
