“…The mathematical model of this submodule is based on [30,31,32]. This submodule considers the transverse and longitudinal influence of the optical performance as well as its geometric design parameters, in the calculation of the total amount of the collected and reflected thermal energy by a linear Fresnel reflector.…”

The objectives of this study were to develop a realistic simulation tool to analyze solar thermal cooling systems driven by Fresnel collectors and carry out a case study in which the performance of a solar cooling system of 190 kW located in Riyadh is simulated to demonstrate the functionality and potentiality of the developed tool. This tool is based on an integrated mathematical model that considers the ambient conditions, the thermal loads of the building, the pre-sizing data of each of the components of the system and the simultaneous interaction among them, to conduct a realistic, simple, and precise analysis. A demonstrative simulation example was performed. During the month of July, with a solar opening area of 704 m2 and a tank of 35200 L, a total amount of 47,5 MWh of cooling energy was obtained, with a reduced contribution of the auxiliary system (5,6 MWh) and a minimum number of solar collector system deactivation hours (0,7 %). The daily COP of the absorption machine remained above 0,69. The obtained results from the case study with the simulation tool allowed to verify its functionality, capabilities and correct operation to carry out hourly and parametric studies of this type of systems.

“…Bu çalışma sonucunda her iki taraftaki son aynanın merkezi ile merkez çizgi arasındaki mesafenin soğurucu yüksekliğine oranının 0,9 ile 1,2 arasında olması önerilmiştir. [8]'de küçük ölçekli doğrusal Fresnel yansıtıcının enine ve boyuna parametrelerinin performansa etkisi incelenmiştir. Bu çalışmanın temel amacı alıcı yüksekliği, ayna uzunluğu ve genişliği gibi tasarım parametrelerinin soğurucu tarafından emilen enerji üzerindeki etkisinin gösterilmesidir.…”

Bu çalışmada Mathur metodu kullanılarak değişken ayna aralıklarına sahip bir doğrusal Fresnel yansıtıcı tasarımı yapılmıştır. Belirlenen soğurucu yüksekliğinde ve üç farklı ayna genişliğindeki kuzey-güney doğrultusunda bir Doğrusal Fresnel Yansıtıcının optimum konfigürasyonu bulunmuştur. Her bir ayna genişliğine ait tasarımda aynı alana sahip düz ve silindirik soğurucuların etkisi incelenmiştir. Analizde kullanılan ışınım değerleri ASHRAE metodu kullanılarak Şanlıurfa için hesaplanmıştır. Analiz sonucunda, 42.44 yoğunlaştırma oranında, silindirik soğurucu tipli bir doğrusal Fresnel yansıtıcıyla yaz aylarında ortalama 5.2 kWh, ilkbaharda 3.2 kWh ve kış aylarında 1.2 kWh'lık enerji toplamanın mümkün olduğu görülmüştür.

“…In another work, they analyzed a LFR with two different configurations such as flat mirrors and a parabolic shape reflector. As stated in the results, the maximum exergy performance is on the condition of 700 K. Also, a parametric study for identifying the thermal performance of a LFR has been carried out by A. Barbon et al The considered parameters are mirror length and width, and receiver height. Cagnoli et al numerically analyzed the performance of utilizing encapsulated tubes or evacuated tubes in the linear Fresnel collectors.…”

Negative environmental impact of fossil fuel consumption highlight the role of renewable energy sources and give them a unique opportunity to grow and improve. Among renewable energy sources solar energy attract more attention and many studies have focused on using solar energy for electricity generation. Here, in this study, solar energy technologies are reviewed to find out the best option for electricity generation. Using solar energy to generate electricity can be done either directly and indirectly. In the direct method, PV modules are utilized to convert solar irradiation into electricity. In the indirect method, thermal energy is harnessed employing concentrated solar power (CSP) plants such as Linear Fresnel collectors and parabolic trough collectors. In this paper, solar thermal technologies including soar trough collectors, linear Fresnel collectors, central tower systems, and solar parabolic dishes are comprehensively reviewed and barriers and opportunities are discussed. In addition, a comparison is made between solar thermal power plants and PV power generation plants. Based on published studies, PV‐based systems are more suitable for small‐scale power generation. They are also capable of generating more electricity in a specific area in comparison with CSP‐based systems. However, based on economic considerations, CSP plants are better in economic return.
