HVAC control solution for the cruise cabin of the future
Beckhoff | Heating, ventilation and air conditioning (HVAC) control systems developed by Beckhoff Automation and Danfoss were installed in 80 cabins on Cunard’s luxury cruise vessel Queen Mary II during her 2016 refurbishment. The Beckhoff control system reduces energy consumption in the cabins and ensures continuing passenger comfort. The energy-efficient solution is achieved by combining the AB-QM pressure-independent balancing and control valves supplied by Danfoss with a Beckhoff room automation system comprising the eXtendable Room Box (XRB) including a BC9191 Room Controller and the TwinCAT Building Automation software. The successful cruise ship installation has demonstrated the degree to which optimised HVAC systems in conjunction with advanced automation systems can reduce energy consumption and maintenance requirements. As a result, costs can be saved while at the same time enhanc ing passenger comfort.
