Experimental Performance exploration of Parabolic Trough Solar Collector with Solar Tracking System
Abstract
The investment of the solar energy needs to be specific mechanism represent by using concentrates solar operating principle of solar radiation falling assembled on the ground and focus on the part that is intended to benefit from it ,depending on the purpose or goal of the design , and in the current study , the objective of study is 1- Heat the water 2- Study the thermal performance of the solar collector To achieve the objective of the study was the study of manufactured parabola system to collect sun's rays at the center of the solar collector. For obtaining, a highest thermal energy utilized to raise temperature of water. Depending on the purpose of the study the measurement were carried out and the accounts in winter season at (January) & summer season at (May) at the University of Tikrit as site. Where they were manufacturing pickup Cylindrical Trough Solar Collectors (PTSC) length (2.4m) and a width (0.8m) and area (1.92〖 m〗^2) was packing bow inverter radiation (Aluminum Foil) to increase the reflected rays on the absorber tube was installed on the base of animations of iron and equipped with control works to track the movement of the sun by using automatic sensor tied at the top of the solar collector, In these study used Two kind of Absorbent tube, length (2.4m). 1-The Absorbent tube made of copper outer diameter (0.03m) and internal (0.028m) painted in black color. 2- The copper tube dyed in black and coated by glass tube outer diameter (0.036 m) and internal (0.034 m) vacuumed from the air. Also we use a tank capacity (80L) for storage of the hot water. Lasted experiments in winter season at (January) & summer season at (May) using one values of mass flow rate (m° = 0.02Kg / sec) The results showed that the efficiency of the system and useful thermal energy that have been obtained using evacuated glass tube were higher than those obtained from the tube copper and proportionate directly proportional to the mass flow rate of the water and the amount solar radiation falling on the surface of the earth and that the higher efficiency of the system (46.68%).
