AF AeronMollier has recently won a contract with Havyard Ship Technology on design and delivery of Heating, Ventilation and Air-Condition plant - HVAC, to 5 new ferries to be built for Fjord 1. The contract also includes delivery of AERON Energy Recovery System (AERS) which is a new innovative system developed to achieve optimal energy efficiency.
The ferries are referred to as an industrial revolution with its very strict environmental and energy efficiency requirements. The ferries will be powered by battery during the entire peak time and advanced data tools are used to achieve the highest possible energy efficiency.
AERS systems are the most advanced solution for energy efficiency and are very relevant to electrically powered ships, hybrid ships, diesel-powered ships that are docked from time to time, as well as cruise- and passenger ships that often have a high energy consumption for HVAC. The system is based on water-cooled heat pumps that can utilize both heating and cooling from the heat pumps to be used on the ships. With this solution heat and cooling can be produced in a very energy-efficient manner. This system utilizes heat from the sea in the heat pump, but can also be coupled with the ship's high and low temperature systems to utilize excess heat from diesel engines if they are in operation.
AF AeronMollier has developed innovative Energy-friendly solutions
"We have worked systematically to be able to offer our customers good solutions that optimize the energy consumption and are very pleased that Havyard Ship Technology has chosen AF AeronMollier on these projects," says Heidi Nag Flikka, Managing director of AF AeronMollier.
“Until now, many shipowners have not had a very strong focus on energy-friendly solutions, as there has been available a lot of excess heat from the main engines. However, within this area, there has been a major change in the construction of several battery powered ferries with electric propulsion, as well as hybrid solutions with traditional motors and electric propulsion. After the main engines, HVAC plants are one of the most material consumers of energy on cruise- and passenger ships. Energy-efficient solutions are therefore important also for this segment. In addition, we also see an increased focus on energy saving for other types of ships, and we see future opportunities within this segment”, concludes Flikka.
