Space cooling has a long history of adopting unconventional ways. The vortex tube cooling system (VTCS), a nontraditional cooling system with no moving parts, is the subject of this research. It was designed using CAD and parameters culled from the literature. This system's design includes a control valve, and a cold air orifice. To achieve the best cooling effect, unplasticized polyvinyl chloride (uPVC) material was employed in the design. By employing the hot and cold ends of the tube, it was feasible to segregate warm and cold air. The amount of hot air discharged through the tube was varied to experiment a hot-air/cold-air mass fraction for the most cooling at different inlet pressures. In these two sets of testing, the inlet air pressure and mass percentage of hot air in the vortex tube were investigated. In the design of the vortex tube, ABAQUS finite element software was used (for simulation/visualization of properties such as pressure distribution, temperature distribution, and velocity) for both comparative and validation reasons. Physical experimentation yielded a temperature of 22.3°C, which was 9.4°C lower than the entrance air temperature. The finite element simulation projected a lower temperature of 19°C. When the hot air mass percentage was set to 80%, both the simulated model and the prototype showed the best cooling performance. At maximum cooling with an 80 percent hot air mass fraction, the input air pressure for the prototype and simulated model was 4 bar and 2.6 bar, respectively. [ABSTRACT FROM AUTHOR]

Despite, other operational disciplines like projects, risk, health & safety, environment, and quality management have a variety of global frameworks and models, asset and maintenance management has just recently been created. To help practitioners recognize the variables and constructs that might support decisions towards effective and efficient physical asset management, a variety of organizations, groups, consultancies, and researchers have provided numerous models, terminologies, and frameworks. According to Global Forum on Maintenance & Asset Management (GFMAM) most recent framework, ensuring the asset value is effectively exploited requires considering sustainability as one of the principal components. Although companies have clearly established processes for asset management, there has not been a comprehensive framework to link physical asset management systems with energy sustainability towards meeting sustainable development objectives. With the growing demand for energy and the resulting worries about the reliability of associated asset that employs these energies to generate value for the organization, global asset sustainability becomes necessary. A sound business technique is no longer asset efficient if the energy performance that goes along with it, is not understood. Using asset management systems to achieve sustainable development is still not thoroughly and independently investigated, both in industry practice and academic study. Continuous enhancement of asset management systems under the context of sustainability requires a robust study and framework that will allow organizations to understand the various established subject groups and principles within the performance of asset management system and their contribution towards sustainability-- thereby ensuring that: (i) The 6 subject groups and 39 principles of the asset management landscape by GFMAM are evaluated based on their influence on the energy sustainability & sustainable development perspective: and (ii) Organizational major targets and performance indicators under these subject groups are aligned in the context of sustainable development. The following issues will be addressed in this paper: The current state of energy sustainability measured and how they can be linked to asset management system performance, and how can this be tied back to business performance.
