Excessive Condensation from Not Using Night Cover

Likely causes

Night cover not used — direct high-humidity outside air infiltration

Check: Check if night cover is used after business hours — not using increases energy 30~40%; verify store nighttime temperature is at or below 18°C

What to do: Instruct use of night cover (immediately after closing); instruct maintaining store at +18°C at night; replace damaged cover

Store night temperature too high — dew point drops

Check: Measure store temperature after closing — should maintain below +18°C at night; condensation occurs in high-temperature + high-humidity environment

What to do: Maintain night-time cooling settings or reduce ventilation; manage to achieve indoor temperature below +18°C at night

Night cover damaged — poor sealing

Check: Visually inspect entire night cover surface — tears, separation at joints, poor bottom contact; if condensation continues after use = cover failure

What to do: Replace damaged night cover; verify bottom contact fixation (magnet or retaining pin); staff training on proper usage

Field tip

Not using night cover = 30~40% energy increase + condensation — maintaining store at +18°C at night paired with night cover use is the best approach; verifying cover bottom contact is key
