英文摘要	Solar desalination emerges as a promising solution to extract potable water from brackish sources in arid regions facing challenges of clean, drinkable water and electricity. This study conducted energy, exergy, and economic analyses of a novel pyramidal solar still (PSS) incorporating an ultrasonic fogger, Phase Change Material (PCM), and fins. The results were compared with those from a solar still equipped with only fins and PCM, as well as a conventional solar still. Three different experimental setups were designed and fabricated: Case I - Conventional Pyramidal Solar Still (CPSS), Case II - SS with PCM, fins, and ultrasonic fogger (MPSS1), and Case III - SS with PCM and fins (MPSS2). Experiments were conducted in Surat city of Gujarat, India, in March 2024, utilizing Lauric acid as the PCM for energy storage and aluminum fins in the absorbing basin. The obtained results demonstrated a remarkable improvement in total accumulated productivity, with MPSS1 (6.07 l/m2) and MPSS2 (4.45 l/m2) showing enhancements of 143.78 % and 78.71 %, respectively, compared to CPSS. MPSS1 exhibited superior energy efficiency of 44 %, with enhancements of 41 % and 57 % compared to MPSS2 and CPSS. Furthermore, the enhancement in exergy efficiency in MPSS1 was 61.60 % and 89.67 % compared to MPSS2 and CPSS, respectively. Economic analysis revealed that the Cost per Liter (CPL) of freshwater for MPSS1, MPSS2, and CPSS was $0.010, $0.014, and $0.019, respectively. This indicates reductions of up to 28.57 % and 47.36 % for MPSS1 compared to MPSS2 and CPSS, respectively. Additionally, CPL for MPSS2 showcased a reduction of 26.31 % compared to CPSS. The payback period for MPSS1 decreased by 23.57 % and 44.37 % compared to MPSS2 and CPSS, respectively. The novel experimental setup (MPSS1) is advantageous for efficient desalination in potable water scarcity regions.
