Indoor/outdoor spaces pose operational challenges on cruise ships

摘要

Passengers on cruise ships like to wander in and out much as they would on dry land, i.e. without having to negotiate doors that open and shut as they pass. But creating such indoor/outdoor spaces onboard ships is demanding given the particular requirements of heating, ventilation and air conditioning (HVAC). Humidity is a major source of those challenges e.g. creating cabins that feature doors which can be opened and thus remove an entire wall to the balcony, says Uwe Jakubowsky, engineering manager at Aerius, the German HVAC specialist. If the temperature inside the cabin is kept low and the air outside hot and humid, as is often the case when the ship operates in warm climates, condensation starts to build within the space. Over pressurising the cabin offers a way to tackle the problem, he tells The Naval Architect.
