Insufficient Cooling Capacity During Peak Summer Heat
Likely causes
Wet bulb temperature exceeds design value (27°C WB) — actual field wet bulb above design
Check: Measure actual peak wet-bulb on-site (3-day average Jul–Aug peak), compare to design basis
What to do: Force VFD fan to max frequency (60–70 Hz) → pre-cool tank to 24–26°C overnight before peak
Tower facing west — direct solar radiation exposure
Check: Check tower orientation and shade; compare tower surface temperature vs shaded zone at 14:00–16:00
What to do: Install shade screen or relocate to east/north orientation (block west/south radiation)
Field tip
Checking fan VFD max frequency and completing fill cleaning 2 weeks before summer peak is the golden window.
