Summary

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 π»π‘”π‘™π‘œπ‘π‘Žπ‘™ = 800 π‘Šπ‘šβˆ’2 and π»π‘‘π‘–π‘Ÿπ‘’π‘π‘‘ = 672 π‘Šπ‘šβˆ’2.
Solar collecting and electrical efficiency are πœ‚π‘π‘œπ‘™π‘™,𝑃𝑇𝐢 =0,6451; 0,5056; 0,2346, πœ‚π‘π‘œπ‘™π‘™,𝐻𝑇𝑃𝑇𝐢 =0,6736; 0,6044; 0,4731 and πœ‚π‘’π‘™π‘’π‘π‘‘π‘Ÿπ‘–π‘π‘Žπ‘™ = 0,3275; 0,36; 0,45, respectively. Analysis has chosen solar WORKCRAFT for promotion in clean power yield, because is effective, (πœ‚π‘’π‘™ βˆ— πœ‚π‘π‘œπ‘™π‘™ )π‘Šπ‘‚π‘…πΎπΆπ‘…π΄πΉπ‘‡ π‘‘π‘Žπ‘¦,π‘›π‘–π‘”β„Žπ‘‘ = 0,223 π‘˜π‘Šπ‘’π‘™ βˆ— π‘˜π‘Šπ‘ π‘œπ‘™π‘Žπ‘Ÿ βˆ’1 , and least complex. Efficiency of solar WORKCRAFT is compared with challenging conventional photovoltaics (PV) and concentrating photovoltaics (CPV) technology in hot dry areas.
