Abstract
Solarno hlajenje predstavlja eno izmed rešitev za zadovoljevanje naraščajočega povpraševanja po energiji za hlajenje objektov. Izbira solarnih hladilnih sistemov je močno odvisna od značilnosti objektov, podnebnih pogojev, tehničnih parametrov in drugih lastnosti, zato s sistematičnim pregledom relevantne literature povzemamo in primerjamo njihovo tehnološko zrelost, ekonomičnost, celotno energijsko učinkovitost, okoljske vplive, kompaktnost in možnosti uporabe. Z različnimi energijskimi kriteriji, med katerimi je prvenstven solarni delež hlajenja, parametre izbranih solarnih hladilnih sistemov najprej optimiziramo. Da bi prikazali njihovo upravičenost oziroma potencial pri zadovoljevanju hladilnih obremenitev z obnovljivimi viri, nato primerjamo najbolj ugodne različice sistemov. Glede na solarni delež hlajenja so uspešnejši solarni hladilni sistemi, ki zadovoljujejo nižje hladilne obremenitve, z vidika izravnanih stroškov hlajenja pa sistemi, namenjeni večjim potrebam po hlajenju. Analizirani toplotno gnani hladilni sistemi imajo v povprečju za 18 % višji solarni delež hlajenja in za 23 % višje prihranke emisij ogljikovega dioksida v primerjavi s fotonapetostnimi hladilnimi sistemi. Z vidika kriterijev finančne upravičenosti so fotonapetostni hladilni sistemi uspešnejši. Pri tem je bistveno upoštevati celotni potencial solarnega hladilnega sistema, vključno z dodatno razpoložljivo električno energijo ali toploto.

Title:Comparative analysis of solar cooling systems
Abstract:
Solar cooling is one of the most promising solutions to meet the growing cooling demand. The selection of solar cooling systems depends heavily on building specifications, climatic conditions, technical features, and other characteristics. Their technological maturity, economic feasibility, overall performance, environmental impact, compactness, and applicability are reviewed and evaluated. The parameters of the selected solar cooling systems are first optimized by applying various energy criteria, mainly the solar cooling fraction. To demonstrate their feasibility and the potential of using renewable energy sources to satisfy the cooling loads, the comparison of the most favorable system configurations is carried out. Regarding the solar cooling fraction, systems with lower cooling loads are more desirable. However, based on levelized cost of cooling, solar cooling systems that cover higher cooling loads seem to be more favorable. Compared to solar electric cooling systems, solar thermal systems have on average 18 % higher solar cooling fraction and 23 % higher carbon dioxide emission savings. Nevertheless, the former have proven to be the more economically viable option. Considering the full potential of solar cooling technologies, the assessment of both the additional electricity and heat is essential for any comparison.

Keywords:solar cooling, cooling systems, comparative analysis, solar thermal cooling, solar electric cooling, solar thermal collectors, economic feasibility
