“…In the last decade, there has been extensive investigation into different aspects of desalination research and development. These include utilizing absorber plates to enhance heat absorption, employing phase change materials for latent heat storage, utilizing nanoparticles to improve thermal performance, and integrating phase change material with fin absorbers [9][10][11][12][13][14][15][16][17]. Several scholars have examined research on the use of absorber fins in desalination systems.…”

This present study conducted an experimental analysis of the use of hollow circular fins (HCF) within the conventional single-slope solar still (CS4) chamber. To enhance energy absorption, the optimal HCF numbers were increased by the available chamber space. The three identical CS4 testing chambers were examined in the climatic conditions of the Sebelas Maret University Faculty of Engineering, located in Kentingan, Surakarta, Indonesia. The HCF absorber is implemented with 176 HCF, 176 HCF, and 216 HCF within the chamber space. The findings indicate that there is a direct correlation between the increased HCF numbers and both productivity and efficiency. The efficiency for 117 HCF, 176 HCF, and 216 HCF is 27.04%, 35.20%, and 42.16% respectively. Therefore, it was determined that correlation analysis significantly contributed to the relationship between the HCF implementation and the different radiation intensities in day-to-day testing. To obtain a more comprehensive analysis, the randomized complete block design (RCBD) experiment in collaboration using least squares regression was conducted to compare the experimental production of CS4 with its predicted value.

“…The latent heat storage increases the water productivity and reduces the exergy efficiency. Benhammou and Sahli (2020) described the investigation of single slope solar still coupled with a separated heat storage system consisting of double glazing solar collector. It showed that daily irreversibility decreases slightly with increasing the water mass and slope angle of collector.…”

The energy storage application plays a vital role in the utilization of the solar energy technologies. There are various types of the energy storage applications are available in the todays world. Phase change materials (PCMs) are suitable for various solar energy systems for prolonged heat energy retaining, as solar radiation is sporadic. This literature review presents the application of the PCM in solar thermal power plants, solar desalination, solar cooker, solar air heater, and solar water heater. Even though the availability and cost of PCMs are complex and high, the PCMs are used in most solar energy methods due to their significant technical parameters improvisation. This review's detailed findings paved the way for future recommendations and methods for the investigators to carry work for further system developments.

This article presents the energy performance and economic assessments of a solar air collector (SAC) and compression heat pump (CHP)-integrated solar humidifier desalination system. The influences of solar heat flux, ambient wind speed and ambient temperature on the energy performance of the system are investigated. The quality of distilled water obtained from the system was assessed. The results showed that the proposed configuration has the maximum distillate output of 22.3 l per day in 14 hours of observations during the summer months. Moreover, the system delivers 100 l of hot water at 46 ± 2°C. The effectiveness of a solar humidifier was raised from 0.16 to 0.97. The coefficient of performance of the CHP was fluctuating between 2.40 and 2.77. The gain output ratio (GOR) was raised from 0.9 to 3.35 during the summer months. The proposed system has a payback duration (PBD) of 27.62 months for 14 hours of operation per day during 252 days in a year. The environmental impact assessments revealed that the system will release 32.35 tons of carbon dioxide emissions during 15 years life span. The quality of water obtained from the system was found to be good and suitable for drinking enriched with minerals.
