Design of a solar absorption cooling system in a Greek hospital
TL;DR: In this paper, the performance and economic evaluation of a solar heating and cooling system of a hospital in Crete, is studied using the transient simulation program (TRNSYS), where the meteorological year file exploited the hourly weather data where produced by 30-year statistical process.
Journal ArticleDOI
Solar cooling technologies in Greece. An economic viability analysis
Theocharis Tsoutsos,Joanna Anagnostou,Colin Pritchard,Michalis Karagiorgas,Dimosthenis Agoris +4 more
TL;DR: In this article, an economic evaluation of two types of solar cooling systems (an absorption and an adsorption system) was made and the analyses indicated that, because of their high investment cost, these systems would be marginally competitive with standard cooling systems at present energy prices.
Journal ArticleDOI
Industrial solar thermal applications in Greece: Economic evaluation, quality requirements and case studies
TL;DR: In this paper, the authors evaluated solar thermal systems in economic terms in comparison with energy equivalent systems such as diesel, LPG, fuel 1500 and natural gas, and eight successful applications of solar thermal system in Greek industry are presented.
Journal ArticleDOI
Solar assisted heat pump on air collectors: A simulation tool
Michalis Karagiorgas,Kostas Galatis,Manolis Tsagouri,Theocharis Tsoutsos,Aristotelis Botzios-Valaskakis +4 more
TL;DR: In this article, the authors evaluated the efficiency of a bioclimatic building of the Greek National Centre for Renewable Energy Sources (CRES) consisting of two heating plants.
Journal ArticleDOI
A Comparative Energy and Economic Analysis of Different Solar Thermal Domestic Hot Water Systems for the Greek Climate Zones: A Multi-Objective Evaluation Approach
TL;DR: In this article , a detailed analysis of different solar thermal systems for domestic hot water production in the different climate zones of Greece is presented, where the analysis is conducted by following the well-known f-chart method and every design is optimized by using energy and financial criteria.
