Energy savings for passenger vessels
In passenger vessels, the heating ventilation and air conditioning (HVAC) system is the second largest consumer of energy after propulsion. It is estimated that up to 30% of the total energy consumption of a passenger ship comes from HVAC systems for cabins, public areas and galley ventilation. When the ship is berthed in the port, the HVAC system even becomes the main energy consumer.
Needless to say the HVAC system is not a negligible value and the gains regarding energy efficiency are more than clear. With increasing fuel costs and fast approaching regulations for emission reductions, innovative developments from land based systems are making their way into the marine markets to help meet these challenges.
