How do we know what the saving is?
Before activation, Arkitech monitors the HVAC system in passive mode to establish a baseline for energy consumption. This baseline is later compared with actual performance once our software actively manages the setpoints. The monitoring period may vary depending on operational factors, and the baseline is updated as different weather conditions occur.
Which factors influence the level of saving?
The level of saving depends on how effectively the HVAC system responds to changing thermal loads. Rapid shifts in occupancy, internal heat gains, or outdoor conditions require dynamic adjustments. In such situations, the system continuously optimizes chilled water parameters in real time to balance passenger comfort with reduced energy consumption.
What factors influence energy consumption onboard of a ship?
The main factors influencing energy consumption in are outdoor temperature, outside humidity, seawater temperature, occupancy, internal ship temperature, sun radiation and internal heat emission by ship’s systems.
What happens when the conditions change quickly, for example a large number of people enters the ship?
The ARK-M20 system monitors real-time temperatures inside the ship especially in spaces such as: passenger cabins, show lounges, restaurants, atriums, or lobbys and when an air temperature increase is detected the ARK-M20 automatically reduces the chilled water temperature to meet the new conditions. When the temperatures are going down or the specific room air conditioner (fan coil or water valve) is closed, the system reverts to the most efficient setting.
How is the system different from other methods on the market?
Unlike other solutions that act only on room temperature, often causing limited savings and passenger discomfort, this system directly optimizes chilled water temperature. It works within the existing chiller controls provided by the manufacturer, ensuring safe operation without risk of malfunction. By combining smart data analysis and automated control, it delivers greater energy efficiency and comfort with minimal installation effort.
