“…Numerous factors influence the cooling load of a building, encompassing both external and internal elements. The climate influences external factors, while internal factors are influenced by the characteristics within the building, including the building envelope, occupancy pattern, and operating schedules [10,11]. Several standards have been published by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) for estimating the cooling load within buildings, as outlined in ASHRAE Standard 183 [12].…”

The global discussion on conserving energy's importance has persisted, paralleling the surge in energy use over two decades. This rise presents challenges for local energy supply to diverse buildings. Designing energy-efficient buildings has become crucial in reducing energy usage and promoting sustainability. This research comprehensively analyzed and assessed thermal-cooling loads within an airport building using Panasonic software. The investigation primarily focuses on evaluating cooling load and thermal dynamics within the airport facility, emphasizing enhancing energy efficiency, and ensuring thermal comfort. Additionally, duct sizing design was conducted to achieve a comprehensive HVAC installation. From the result of the investigation, it was found that the highest Cooling Load at the airport occurs at 4:00 PM, aligning with the peak temperature resulting from heat transmitted into the building, reaching 263,591 Watts for the Airport Lounge and 82,202 Watts for the Luggage Room. Building energy management must be undertaken to minimize the energy consumption during that period. By thoroughly examining thermal-cooling loads within an airport building, this research contributes to decision-making for designing and operating HVAC systems, thereby advancing sustainable building practices.

The use of thermal insulation is one of the most crucial solutions for reducing energy consumption when designing buildings. In this study, we investigate the use of various types of thermal insulation (air, cellulose, fiberglass, mineral wool, polystyrene, and polyurethane foam) to determine the best location when designing. The numerical study is done using ANSYS/FLUENT 16 software and an enthalpy-porosity formalism. According to the study's findings, all heat insulators investigated offer effective insulation, but some of them, like air, have characteristics that make them challenging to employ. The remaining insulators satisfy all requirements for usage as a thermal insulator. Given that it possesses all the necessary characteristics to be used as a thermal insulator, (polystyrene) is one of the most important insulators that are readily available locally. The use of thermal insulation in buildings reduces the need for refrigeration equipment to maintain comfortable conditions, which has a significant negative impact on the environment.

“…We take note of the interest in heat transfer as an essential component in a wide variety of scientific applications, and we take note of the significant impact that heat transfer has on a wide variety of elements of life, such as the following: (electronics, x-rays, optical devices, cooling devices, etc.). The exponential growth of these devices and technologies through miniaturization, data storage, and optimization of the operating rate has led to serious problems in the thermal management of these devices [1][2][3]. This growth has been driven by factors such as data storage, operating rate optimization, and miniaturization.…”

A numerical analysis demonstrates the significance of utilizing nanoparticles to enhance heat transfer in pipes. This research examines the addition of nanomaterials to used metal at concentrations of 1%, 5%, and 10%. Copper is utilized as the pipe material, while carbon nanotubes serve as the nanomaterial. The analysis was conducted with the ANSYS/FLUENT 16 enthalpy-porosity formulation. The results of this study indicate that the use of nanoparticles increases heat transfer, and that the more the percentage of nanomaterials, the more pronounced the improvement in heat transfer through the tube, as the inclusion of 10% nanomaterials greatly improves heat transfer. This study can be utilized to enhance heat transmission in air conditioners.
