Thermal Systems and Energy Efficiency

The use of thermal energy systems in a multitude of industrial processes, as well as in homes, makes a direct impact on their energy consumption. Improving the energy efficiency of thermal energy systems is a primary automated engineering goal. This chapter examines issues related to the efficiency and effectiveness of thermal systems, questioning their optimal performance. Major subjects to be addressed include functional interface integration perplexity; energy source variability, most notably from renewables; the need for advanced thermal materials; and the deployment of intelligent control mechanisms. Other impediments, focused on the economically usable optimum, regulatory pressure, and technological advancement, hinder wide acceptance. Confronting the multitude of issues thermal systems face, this chapter identifies various opportunities through which these systems could be innovatively modified. Innovations in heating system integration with other renewable energy sources, developing continuous control smart systems, and efficient heat recovery technologies are some notable directions. Particular concentrations are also set on the use of digital twins, artificial intelligence–driven predictive maintenance, advanced thermophysical materials, and predictive diagnostics, incorporating engineering principles, which also deserves further research emphasis.
