May I ask, is it true that the smaller the average temperature difference, the more stable the heating of water by the heat exchanger? In other words, there will be no fluctuations such as sudden increases or decreases in temperature – is that correct?
Not really; the temperature difference is small, so the heat exchange capacity is poor. Stability depends on the traffic on both sides; as long as the traffic remains stable, it will stay stable.

This statement is correct when the system is started up; a small average temperature difference generally indicates a large heat exchange area, which makes it easier for the material to reach a steady state. To keep the material parameters from changing much, I think the most important factor is the quality of the automatic control program design The overall control scheme is good; during programming, a proper balance is achieved among proportioning, integration, and differentiation, which allows the parameters to remain almost stable during operation. The system reaches stability quickly upon startup, and it stops promptly when shut down. Put simply, the control scheme forms the foundation, while the algorithm is the core.
Yes. However, when the temperature difference is small, the heat transfer efficiency is also relatively low.
