Erbil Polytechnic University Jointly with the Ministry of Reconstruction and Housing and Tishk International University Complete Another Training Course

On Wednesday, the 31st of May 2023, in the presence of the Minister of Reconstruction and Housing of the Kurdistan Regional Government Mr. Dana Abdulkarim, president of Tishk International University (TIU), Dr. Abdulsamad Slahuddin, the Erbil Polytechnic University Rector Representative Asst. Prof. Dr. Botan Majid Asinger, the closing ceremony of an engineering course on “Roads and Bridges” was held in Duhok General Directorate of Roads and Reconstruction.

In a ceremony where the Deputies of the Minister of the Reconstruction and Housing, several consultants and general directors of the ministry and a number of government officials were present, the Minister of Reconstruction and Housing delivered a speech. He said: “I am pleased to meet with engineers, teachers and the ministry team in this beloved city to award certificates to the participating engineers. Of course, opening of such courses will influence the development and implementation of service projects.”

The course was supervised by both the Erbil Polytechnic University and Tishk International University, in which 40 engineers of the Ministry participated, and the lessons were taught by teachers of both universities. At the end of the ceremony, graduation certificates were awarded to the engineers and the honorary certificates were awarded to the lecturers.

It is worth mentioning that a three-month course (General Specification of Roads and Bridges) was opened for 70 other engineers of the Ministry of Reconstruction and Housing of the Kurdistan Regional Government in Erbil under the supervision of both Erbil Polytechnic University and Tishk International University.

  • One of the biggest problems in the world that we live in nowadays is the environmental pollution caused by an overconsumption of energy. When fossil fuels are burned to generate energy, it emits CO2, which is a leading cause of air pollution. Solar energy has the potential to replace fossil fuels as an alternative source of renewable energy. A photovoltaic solar system is one type of solar system that can convert the sun's light into electrical energy. One of the issues with PV panel is the high temperature of PV cells, especially in summer season when the ambient temperature can rise up to 50℃. As the temperature of solar modules increases, both the output power and the efficiency of PV panel decrease. To improve overall performance while extending the solar module's lifespan, this study proposes lowering photovoltaic cell temperature by using water cooling chamber installed at the back side of the PV panel. The proposed solar panel was developed and designed through both experimental study and ANSYS Fluent simulation. The photovoltaic module that was designed has a water-cooling chamber for the purpose of providing cooling under the condition of Erbil city. The rear side of the photovoltaic panel is cooled using water cooling chamber. The water-cooling chamber can absorb heat dissipation from the photovoltaic panel. The proposed cooling system for the solar panel is a closed cycle, and the cooling water is in contact with the back of the PV panel at different flow rates.  According to experimental setup, the maximum water flow rate of 3.5 l/min gives the optimal heat transfer rate. Finally, results demonstrated an improvement in electrical efficiency by the following percentages: 10.42%, 11.87%, 13.77%, 18.09%, and 19.72% when the water volume flow rates of 1.5, 2, 2.5, 3, and 3.5 l/min, respectively, were applied. Meanwhile, the thermal efficiency of the PV system is 49.7% with a water flow rate of 1.5 l/min. and, the thermal efficiency recorded 79.2% when the system operated at a flow rate of 3.5 l/min.
