- Domain
- CHILLED_WATER_SYSTEM
- Reference standard
- EN 50600-3-1 / ISO 50001
What it means
Scale and corrosion reduce heat exchange: delta T narrowing at equal load, rising consumption and worsening PUE.
Probable causes
- Inadequate water treatment (hardness, pH, inhibitors)
- Insufficient filtration (dirty strainers)
- Poor quality make-up water
- No periodic analysis
Where to start
Analyse trends: water delta T narrowing at equal load and rising specific consumption are the signature of fouled exchangers.
