Special Issue Information

Dear Colleagues,

Nowadays, the utilization of fossil fuels has been decreasing every year, and new investments in renewable energy technologies have become a global priority. Utilization of renewable energy sources such as solar, geothermal, wind, biomass, and hydro provides people in developing countries access to energy to cover demand for electricity, heating, and cooling energy. In developed countries, it enables the improvement of energy efficiency in the energy sector and reduces environmental pollution. It helps all countries in the world to ensure energy security. Renewable energy systems can be used at micro, small, and large scales. Rapid development of renewable energy technologies means that their availability is becoming more common while their costs are decreasing. Different technologies are dedicated to specific climatic, environmental, local, and social conditions. Research studies have been conducted to increase efficiency of energy conversion in different devices and machines and the total energy performance of renewable energy systems. Many of such studies deal with analyses of operations and the effectiveness of integrated multi-energy source systems, where different renewables are used in a complimentary manner to each other, covering energy demands of different types of energy users. In this Special Issue, potential topics include but are not limited to the following:

  • the theoretical and technical potential for the utilization of renewable sources for local/regional/global applications
  • modelling of operations and the energy performance of renewable energy devices and systems for different applications
  • processes and methods to design/build/apply different renewable energy systems
  • new achievements in renewable energy technologies for micro or large scale application.
  • Analysis of the operation and effectiveness of multi-renewable energy source systems applied for different types of users
  • applications of renewable energy technologies in buildings
  • economics of renewable energy systems in relation to the scale of their applications and state of economy of the country, regulatory energy market, and other legal entities

As global mineral resources at shallow depths continue to deplete, thermal hazards have emerged as a critical challenge in deep mining operations. Conventional localized cooling systems suffer from a fundamental inefficiency where their cooling capacity is rapidly dissipated by the main ventilation airstream. This study introduces the innovative concept of a “microclimatic circulation zone” implemented through a convection–radiation cooling system. The design incorporates a synergistic arrangement of dual fans and flow-guiding baffles that creates a semi-enclosed air circulation field surrounding the modular convection–radiation cooling apparatus, effectively preventing cooling capacity loss to the primary ventilation flow. The research develops comprehensive theoretical models characterizing both internal and external heat transfer mechanisms of the modular convection–radiation cooling system. Using Fluent computational fluid dynamics software, we constructed an integrated heat–moisture–flow coupled numerical model that identified optimal operating parameters: refrigerant velocity of 0.2 m/s, inlet airflow velocity of 0.45 m/s, and outlet aperture height of 70 mm. Performance evaluation conducted at a mining operation in Yunnan Province utilized the Wet Bulb Globe Temperature (WBGT) index as the assessment criterion. Results demonstrate that the enhanced microclimatic circulation system exhibits superior cooling retention capabilities, with a 19.83% increase in refrigeration power and merely 3% cooling capacity dissipation at a 7 m distance, compared to 19.23% in the conventional system. Thermal field analysis confirms that the improved configuration successfully establishes a stable microclimatic circulation zone with significantly more concentrated low-temperature regions. This effectively addresses the principal limitation of conventional systems where conditioned air is readily dispersed by the main ventilation current. The approach presented offers a novel technological pathway for localized thermal environment management in deep mining operations affected by heat stress conditions. Full article
