Large cruise ships that sail the warmer regions of the earth such as the Caribbean, the Mediterranean or the Persian Gulf, continuously produce a lot of condensate water. The air is cooled down inside the heat exchangers of the numerous air- conditioning units to a temperature below the dew point of the outside atmosphere. This causes a large fraction of the air humidity to fall out as liquid water (condensate), which accumulates inside the collection pan at the bottom of the air conditioning (AC) units.
