The growing demand for energy-efficient HVAC installations has been in a steady increase the past several years. Through consistent development work and testing new technological advances, Halton Marine has met the MSC Cruisetech demand by supplying, as the first one in the world, a state-of-the-art energy efficiency control system for cabin ventilation on a board a cruise ship. The system does not only provide direct savings in energy consumption, but also contributes to protecting the environment – and needless to say – without sacrificing the customer comfort. On the contrary, connecting the cabin ventilation to a well-designed network improves customer comfort.
About the cabin ventilation system
Halton’s intelligent and energy-efficient cabin ventilation systems, reduce the energy demand therefore contributing to the respect of the environmental. Within the local energy efficiency system, Halton’s control systems are connected to switches that can detect the presence of passengers in the cabin, so that the ventilation can be set to serve in a energy-efficient mode while the cabin is not occupied.
Furthermore the balcony door switch indicates to the cabin ventilation system whether the balcony door is open or not.
In addition to local energy efficiency system, an advanced energy efficiency technology operating in a network is introduced on board MSC Fantasia.
Advanced energy efficiency for cabin ventilation
Connecting a cabin ventilation system to a network enables substantial savings in energy consumption on board ship. One of the best benefits is the active operation between AHU (Air Handling Unit) and cabin units. Data from cabin units is collected to control the AHU in two ways:
- Adjusting the fan operation to optimal level
The AHU control calculator monitors and collects data of the pressure-independent VAV units, as well as functional details. Collected data enables the calculator to determine the pressure in front of each unit. Pressure data is used to optimize the fan operation, which cuts down the unnecessary energy consumption. All this is done without losing any comfort in the cabins.
- Minimizing the need of unnecessary electrical re-heating
The AHU control calculator collects the temperature information from each cabin unit. Based on the re-heater’s utilization rates, AHU’s heater valves are controlled to cut down unnecessary electrical heating inside the cabin unit. The supply air is kept actively to optimum temperature level.
In addition to energy efficiency, connecting a cabin ventilation system to a network also offers other benefits such as the possibility to control, monitor and adjust cabin indoor climate, centralized via the network. The Halton Marine supervision software runs on a standard computer and offers an excellent tool for Hotel Management and HVAC Engineering. The software offers an overview all the way from complete cabin ventilation system to each cabin that can be individually adjusted, controlled, and monitored via the network.

MSC Fantasia is the largest ship ever built by a European ship-owner with 133,500 tons of bulk weight, 333 meters long, 60 meters high and 27,000 m2 of public spaces dedicated to its 4,000 guests. The luxurious cruise ship also complies with all the anti-pollution regulations for a complete safeguarding of the marine eco-system and environment. Part of this is the energy efficient cabin ventilation system supplied by Halton Marine.
