System optimization

Definition

System optimization is the process of making a system as effective or functional as possible, often through the careful adjustment of various parameters to improve performance. In the context of thermoelectric devices, this can involve fine-tuning heat exchangers to maximize energy transfer efficiency or integrating different energy sources in hybrid systems to enhance overall output. Effective system optimization not only increases performance but also reduces costs and energy waste, making it essential for both heat exchanger design and hybrid systems.
