Past to Present: Solar Chimney Power Technologies

Abstract

This study introduces the solar chimney power technology, which is a solar thermal energy system. One of the renewable energy resources, this system is an energy transformation system in which solar energy and wind energy are used together. In this system, the air that is heated with solar energy ensures the production of electric energy by moving upwards with the suction effect of the chimney and rotating the turbine that is placed inside the chimney. In this review, the main principles and characteristics of this system are discussed and the developments on the experimental and theoretical investigations carried out with regard to the solar chimneys around the world especially in recent years are shared with the readers. With the study, it is aimed to provide upto-date information to readers who are interested in this subject.

Technoeconomic Analysis of 1 MWp Grid Connected Solar Power Plant in Konya (Türkiye)

“…According to the countries' energy policies, solar energy is expected to meet 11% of global electrical energy consumption in 2050 [9]. In short-term plans, it is estimated that renewable energy sources will be the energy source with the fastest growth rate with a growth rate of 7.6% until 2030 [10].…”

An Improved Design and Analysis of a Solar Receiver

“…Solar energy can be taken as the most efficient energy source because it is a clean renewable energy source and is possible to widely distributed [3]. There are many different ways of using solar radiation in the forms of power for heat engines, thermoelectric power generators (such as by Peltier elements or steam engines), photovoltaic cells for direct electricity production, crop dying, power for refrigerators and air conditioners, desalination of sea water and domestic hot water production [4][5][6][7][8][9]. Concentrating solar power (CSP) gets public attention in a wide extent and is thought as one of the most efficient alternatives [10].…”

“…They optically investigated an open receiver of a conical cavity in the shape of a helical tube in order to improve the receiver's optical performance. It is revealed that the helical conical shape with an aperture area of 0.01606 m² absorbed an average flux value of about 2.6 x 105 W/ m² [8]. Another investigation has been run by Rafeu and Kadir (2012) used three experimental models with various geometrical sizes and solar dish concentrators with a diameter of about 0.5 m in order to search the geometry's effect on a solar temperature and irradiation by maximizing the solar fraction under the Malaysian environment.…”

Şanlıurfa’nın Geleneksel Rüzgâr Yakalayıcıları: Kaybolan Bir Geleneğin Günümüze Kadar Gelen Örnekleri

“…Şanlıurfa'daki rüzgâr yakalayıcılarının sadece eyvanı havalandırmak için tasarlanmaları da özgün niteliklerinden biridir. Bazı evlerin eyvanlarını havalandıran bir ya da iki rüzgâr yakalayıcının varlığı ise yine Irak'taki örneklerle benzerlik oluşturmaktadır.Günümüzde kullanılan bina bileşenlerinin çevre üzerinde oluşturacağı etkiler gittikçe daha çok önem kazanmaktadır[56]. Kökleri Antik dönemlere dayanan geleneksel rüzgâr yakalayıcılarının günümüze kalan örnekleri birçok ülkede özellikle korunmakta, sürdürülebilir pasif havalandırma ve soğutma sistemleri için ilham kaynağı olmaktadır.…”
