What is How large must the buffer tank be??

The buffer tank size determines the daily start-stop cycles: a tank that is too small forces frequent starts (wear), one that is too large increases investment costs — rule of thumb: storage capacity should be able to accommodate at least 2–4 hours of CHP heat output.

What the AI reads from these values

What the AI reads
  • Determination of minimum operating time to reduce start-stop cycles
  • Monitoring of the volume to accommodate the daily heat output
  • Analysis of temperature gradients to avoid material fatigue
  • Calculation of operating duration to minimize mechanical wear
Scenario

Monitored: continuous

The scenario: if the differential becomes smaller, the CHP unit extracts less heat, resulting in lower overall efficiency and cogeneration benefit. The AI: detects the shrinking differential early, before the amount of heat collapses visibly. It identifies the trend before the limit value is reached.

Why this matters

Correct dimensioning reduces mechanical stress from start cycles and thus lowers maintenance costs. An optimally dimensioned tank enables stable continuous operation. This extends the service life of the components and ensures full utilization of the CHP efficiency.
