AERIUS Marine GmbH is a market leader in design of maritime HVAC solutions and a global player in the fields of piping, refrigeration and fire protection. For a cruise liner project, AERIUS has asked conmecs to evaluate the ventilation system configuration of different passenger cabin designs.
energy saving devices (ESD)
There are a lot of different energy saving devices (ESD) on the market, e.g. pre-swirl fins, ducts (Schneekluth, Mewis), and post-swirl devices (costa bulbs, rudder fins and hub fins). The suppliers promise efficiency rates, which lie within achieved rates of former projects and the spread is often relatively high, e.g. savings of “2 up to 6%”. For ship owners it is difficult to decide, which device is the best solution for their particular ship design.
reefer cargo hold ventilation
About ten years ago the proper ventilation of perishable goods was an issue for some ship owners and operators. Many reefer cargo hold ventilation systems were designed with a weak performance and the cooling units of containers failed during transport due to intake temperatures above the cooling units maximum design temperature. This problem has been solved for many container ships due to the design of ventilation systems according to new regulations, which take into account conservative fresh air volume rates.
