KNUD E. HANSEN A/S, in cooperation with Novenco Marine & Offshore A/S, have contracted with Carnival Cruise Line to install state-of-the-art HVAC upgrades on their Victory, Triumph, Conquest and Spirit Class cruise ships, in order to improve the overall operational efficiency of their fleet.
Owner’s newbuilding requirements often specify excessive capacity for HVAC systems in order to ensure passenger comfort while cruising in tropical climates. This means that there is significant potential for operational optimization when the vessels are in less demanding climates or in transitional periods where there are fewer passengers on-board.
Knud Hansen A/S explain that an HVAC operation upgrade to these cruise ships will ensure that the system is taking advantage of the simultaneous factor for persons and for various heat sources such as entertainment equipment, so that cooling capacity is transferred to the areas where needed. The basis of this technology, is to monitor the passenger flow and occupancy of each area. Ventilation is reduced to a minimum for unoccupied areas in order to save both electrical power and chilled water.
The new generation of the “TimeSchedule” and “Energy Saving Calculation” system, can be interfaced to most existing HVAC HMI control systems, and is therefore applicable to most vessels, without exchanging the HVAC HMI.
KNUD E. HANSEN A/S and Novenco Marine & Offshore A/S in Denmark will manage the upgrades in co-operation with the local KNUD E. HANSEN A/S office in Fort Lauderdale, FL, USA.
