Abstract

The growing demand for air conditioning systems has driven research into alternative applications, such as seawater desalination. This study evaluates the performance of a modified window air conditioner (WAC) integrated with a vortex generator for desalination. Experiments were conducted using R410A refrigerant under four conditions: closed container (CC), without vortex (WV), connected vortex (CV), and separated vortex (SV). Seawater was heated via the condenser to 55–60°C, controlled by a thermostat, and data was collected every five minutes over eight hours. The thermodynamic properties of R410A were analyzed using Refprop software to determine refrigeration effect (RE), compression work (CW), and coefficient of performance (COP). Results indicate that the SV configuration achieved the highest evaporation rate (5.01 kg) but led to a lower COP (3.91) due to increased condenser temperature and compressor workload. Conversely, CC yielded the highest COP (5.08) by stabilizing the evaporator air temperature and reducing compressor effort. These findings suggest that vortex generators enhance evaporation rates but reduce system efficiency. Further research is needed to optimize vortex generator configurations to improve desalination efficiency while minimizing COP reduction.

Abstract

The utilization of water resources as renewable energy through waterwheels presents an environmentally friendly alternative, however, its efficiency requires improvement through technological modification. This research investigates two design modifications: a 45° Angle Cap (AC) and a Water-Filled Angle Cap (WFAC), in comparison with a waterwheel without a Cap (WC). Experiments were conducted at discharges from 1 to 10 m³/h with a constant torque load of 0.05 N-m. The highest efficiency of 57.08% was achieved in the AC 45° configuration at 1 m³/h, generating 1.09 watts of power, while the WFAC 45° yielded the highest power output of 2.88 watts at 10 m³/h with an efficiency of 14.50%. Although increasing discharge generally led to higher power input, it was accompanied by a decrease in efficiency across all configurations. Among all three variations, WFAC 45° demonstrated superior performance at higher discharges, indicating its potential for enhancing the power and efficiency of overshot waterwheels.

Abstract

Porosity in solid materials plays a crucial role in controlling gas pressure behavior and diffusion, particularly in carbon absorption processes within Carbon Capture and Storage (CCS) systems. This study aims to investigate the effect of porosity variations on pressure changes of CO₂–O₂ gas mixtures in nickel slag rocks as potential carbon-absorbing materials. The research method employed a literature review based on various studies discussing the physicochemical characteristics of nickel slag, carbonation mechanisms, and gas interactions within porous structures. Key parameters analyzed include pore size distribution, channel connectivity, and diffusion rate affecting pressure dynamics during gas–solid reactions. The results indicate that highly porous nickel slag experiences a faster pressure drop due to more intensive carbonation reactions, whereas low porosity limits gas transport and slows the process. In conclusion, porosity is a dominant factor governing pressure dynamics and the efficiency of CO₂ capture in nickel slag materials.

Abstract

The absorption of CO₂ gas by solid materials is an important approach in the development of Carbon Capture and Storage (CCS) technology. Nickel slag, as a solid waste product of nickel smelting, has the potential to be used as a carbon absorbent material as well as a construction material. This study analyzes the effect of inter-particle layer partitions in nickel slag on CO₂ absorption and its implications for slag utilization. The method used is a literature review of journal articles and proceedings discussing the physicochemical properties of nickel slag, types of partitions, diffusion pathways, and carbonation performance. The results of the study show that the presence of solid-solid, solid-liquid, pore/crack, and chemical partitions expands the specific surface area, provides active reaction sites, and forms effective diffusion pathways, thereby increasing the capacity and rate of CO₂ absorption. Engineering the morphology of partitions through mechanochemical activation or chemical treatment is an important strategy for optimizing the function of nickel slag in supporting the application of CCS and the circular economy of industry.

Abstract

Evaporators with vacuum and heating systems are increasingly being used in the evaporation process of essential oils for aromatherapy due to their ability to increase efficiency without damaging the quality of volatile compounds. Their working principle is to lower the partial pressure so that the oil's boiling point can be reached at a lower temperature. Under these conditions, the active compounds in essential oils can be optimally evaporated without degradation due to excessive heat. This technology is crucial given the sensitivity of essential oils to high temperatures, as the chemical components in essential oils are highly stable. This study reviews various studies and scientific literature discussing the operating principles, system design, heat transfer characteristics, and temperature control techniques of modern evaporators. A descriptive-analytical approach was used to identify technological trends and the advantages of applying vacuum and heating systems to the aromatherapy industry. The review results indicate that this system combination increases thermal efficiency, accelerates evaporation rates, and maintains the aroma profile and chemical quality of the oil. Furthermore, the use of an automatic temperature control system improves process precision, reduces the loss of active compounds, and supports better energy efficiency compared to conventional heating methods. This technology holds great potential for the development of modern, stable, efficient, and environmentally friendly aromatherapy diffusers.
