What is a plate heat exchanger?

Thermally couples the engine cooling circuit to the heating flow; primary inlet temperature should be above 65 °C — a fouled PWT (limescale, biomass) measurably reduces the transferred heat output.

What the AI reads from these values

What the AI reads
  • Deviation of the primary inlet temperature (setpoint > 65 °C) as an indicator for flow problems
  • Difference between flow and return temperature to calculate the transferred heat output
  • Measurement of pressure loss across the PWT to identify fouling or blockages
  • Correlation between engine temperature and PWT outlet temperature to verify cooling capacity
Scenario

Monitored: continuous

The scenario: the temperature difference decreases, the CHP unit extracts less heat, resulting in lower overall efficiency and cogeneration benefit. The AI: detects the shrinking temperature difference early, before the amount of heat drops visibly. It identifies the trend before the limit value is reached.

Why this matters

A clean plate heat exchanger ensures the maximum thermal yield of the CHP unit and prevents costly emergency shutdowns due to engine overheating. Precise monitoring of PWT parameters enables early maintenance planning before damage occurs. This stabilises the efficiency and extends the service life of the components in the CHP unit.
