“…Transwall is a commonly used semi-transparent WWS which has a water layer in between two glass panes and a semi-transparent absorption plate at the middle In this kind of system, 80% of the incident solar radiation is absorbed by the semi-transparent plate and transmits the remaining 20% [54]. This form of wall thus incorporates both direct gain and indirect gain techniques, and is ideal for areas with high daytime temperatures [55]. In this type of system, baffles have often been used to lessen the flow of convective heat through the walls.…”

Review on Energy and Fire Performance of Water Wall Systems as a Green Building Façade

Glass façades are widely utilized in green buildings. Ensuring fire safety while reducing the energy need without compromising occupants’ comfort is a challenge in the modern-day green buildings with glass façades. One way of achieving both aspects is to construct a water wall system as a building façade. A water wall system has a water layer between two glass panes and can be considered as a glass façade system. The focus of this review, which builds on the published studies, is how water wall systems can help ensure fire safety and reduce energy demand in green buildings. The water layer within two glass panes of the water wall system store the solar radiation heat throughout the daytime, reducing the amount of heat transferred through the building facade. The reduced heat transfer effects lessen the need for air conditioning to sustain the thermal comfort of the building occupants. The stored energy is released during the nighttime. The transparency of the water wall system also allows daylight to enter the building, thus reducing artificial lighting needs. Furthermore, the water layer acts as a fire safety mechanism in case of a fire. However, the water wall systems are not much utilized in the modern-day green buildings due to their unpopularity and the unavailability of design guidelines. On the basis of the findings of the literature review, stakeholders and the public are encouraged to adopt water wall systems in green building projects as an energy-efficient strategy and a fire safety mechanism.

“…Naturally, seawater desalination accounts for approximately 67%, brackish water for 19%, river water for 8%, and wastewater for 6% of the total application of desalination systems worldwide. The dominant countries that use the desalination process to produce clean drinking water are Saudi Arabia, Kuwait, the UAE, Qatar, Oman, and Bahrain [5].…”

“…A single-slope solar still (CS4) is a type of solar still that operates as an indirect passive system for purifying seawater into freshwater [3]. Generally, this type of solar still is an eco-friendly technology that relies on solar energy as its primary source [5,6]. The process of evaporating seawater involves the movement of saturated vapor within the chamber space through natural convection (Figure 1).…”

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.
