What is the recommended temperature split across the heat exchanger?

The recommended temperature split across the heat exchanger typically aims for a balance that maximizes thermal efficiency and ensures optimal performance. The choice of the upper 2/3rds reflects the idea that allowing a greater temperature differential at the top of a heat exchanger enhances heat transfer effectiveness.

This design ensures that the temperature gradient facilitates better thermal dynamics, preventing potential condensation issues and enhancing the overall efficiency of the system. When the temperature split is skewed towards the upper section, it allows for better utilization of the heating or cooling potential of the fluid flowing through the exchanger, ensuring that energy transfer is maximized.

Selecting this strategy optimizes the system's performance and energy savings operationally while maintaining a stable workflow during peak outputs or varying loads. This principle is aligned with standard engineering practices concerning heat exchangers, reinforcing its significance in systems design and performance evaluation.
