October 14, 2019 Slide 7

ARKM20 monitors comfort requirements determined by users as well as ambient conditions (temperature and humidity), processing this information to get the most efficient chiller set-points.

To do this ARKM20 not only connects to the chillers, but also with devices, onboard control systems and onshore providing relevant information.

Chillers are designed for optimum performance in specific ambient conditions which may only occur 10% of the time, leaving significant room for improvement of chiller performance while conditions differ from design assumptions up to 90% of the time.

By optimizing the chilled water setpoint continuously the chiller energy consumption decreases significantly.

Connecting

—Introducing ABB ARKM20

October 14, 2019 Slide 8

In a chiller, the electrical power absorbed by the compressormotor depends on the pressure difference that thecompressor has to produce.

Increasing the chilled water set-point, the pressure differencedecreases and therefore the absorbed power decreases too.

Increasing the chilled water set-point temperature by +1°C, theelectric power consumption decreases by 3÷4%.

Important note: the system does not change and affect theindoor temperature set-points.

How does it work – set-point change

Manual process ABB ARKM20The set-point is typically changed by onboard engineer/s depending on the season or climate zone.

ABB ARKM20 defines and sets the optimized chilled water setpoint every 5 minutes.

Variable conditions allow to optimize the setpoint:- night/day- port/navigation- empty/full of passenger- high/low humidity

Creates operational efficiencies

Saving Results & Pay Back

Direct Savings

In a monthly basis, saving is 70 MWh On annual basis saving is around 600-700 MWh Based on energy cost EUR 0,11/kWh, annual saving is around 77K EUR

Pay back time

12 months

Indirect HVAC Savings

With chillers adjusted to most efficient settings for actual demand, additional potential savings on re-heaters and other equipment, on yearly basis around 500-1.000 MWh
