Résumé

Desert area are important for future solar clean power production. Paper analyses three thermal electrical plants, based on Clausius-Rankine absorption working cycle and operated by ammonia-water, i.e.
WORKCRAFT, WORKCRAFT-ORC and WORKCRAFT-SRC. Plants operate day-night time. Three solar collectors, providing heat and sink sources supply and latent storage for operation, are considered, i.e. the parabolic trough concentrating (PTC), a new high temperature PTC, (HTPTC), and the unglazed flat-plate (UFP) solar collector. As input data, plants sink and heat temperatures are 𝑇𝑀𝑐 = 4,0℃ and 𝑇𝐺𝑂 = 304℃; 450℃; 550℃, respectively. Solar irradiance is 𝐻𝑔𝑙𝑜𝑏𝑎𝑙 = 800 𝑊𝑚−2 and 𝐻𝑑𝑖𝑟𝑒𝑐𝑡 = 672 𝑊𝑚−2.
Solar collecting and electrical efficiency are 𝜂𝑐𝑜𝑙𝑙,𝑃𝑇𝐶 =0,6451; 0,5056; 0,2346, 𝜂𝑐𝑜𝑙𝑙,𝐻𝑇𝑃𝑇𝐶 =0,6736; 0,6044; 0,4731 and 𝜂𝑒𝑙𝑒𝑐𝑡𝑟𝑖𝑐𝑎𝑙 = 0,3275; 0,36; 0,45, respectively. Analysis has chosen solar WORKCRAFT for promotion in clean power yield, because is effective, (𝜂𝑒𝑙 ∗ 𝜂𝑐𝑜𝑙𝑙 )𝑊𝑂𝑅𝐾𝐶𝑅𝐴𝐹𝑇 𝑑𝑎𝑦,𝑛𝑖𝑔ℎ𝑡 = 0,223 𝑘𝑊𝑒𝑙 ∗ 𝑘𝑊𝑠𝑜𝑙𝑎𝑟 −1 , and least complex. Efficiency of solar WORKCRAFT is compared with challenging conventional photovoltaics (PV) and concentrating photovoltaics (CPV) technology in hot dry areas.
