Low-pollution utilization of a ship’s excess heat for cooling

COOL4SEA recycles thermal waste energy from the ship’s engines for the air-condition cooling system. This reduces the need for expensive fuel-generated electricity for cooling. In addition, the unique refrigeration technology uses no environmentally harmful refrigerant gases.

The principle behind COOL4SEA’s eco-friendly cooling technology   

    • COOL4SEA’s air-condition cooling technology builds on a well-known principle called Absorption cooling. Absorption cooling has not been widely used on ships. This is primarily because of the previously used design. The processes used in absorption cooling are very sensitive to motion and are quickly disrupted at sea. COOL4SEA has developed, tested and patented a unique design that ensures that the processes can function effectively at inclinations of up to 45°. The design has been developed specifically for dynamic environments and for ships in particular.

A reliable design with minimal maintenance   

    • COOL4SEA’s air-condition cooling technology utilizes the unique properties of lithium bromide. Lithium bromide is not harmful to the environment or to human health. However, it does react aggressively with certain metals. Because of this, COOL4SEA’s cooling equipment is entirely constructed of plastic (PE and PP)and acid-resistant steel (316L). Furthermore, since the design has very few moving parts, the solution is very reliable and requires only minimal maintenance.

Flexible design and installation without downtime   

    • COOL4SEA’s air-condition cooling technology is modular, and the modules can be brought into the engine room through the ship’s hatches while the ship is in service. This means that it is not necessary to lay-up or dock the ship during installation. The modular design ensures that the design of the cooling technology has a high degree of flexibility and can be adapted to the conditions found in most engine rooms.

High efficiency through process monitoring   

    • The cooling occurs as a result of a number of physical/chemical processes. In order to achieve high efficiency, it is important that the processes which are the key to this cooling technology can function optimally. Therefore, the entire process must be monitored around the clock. The only requirement for this is access to an internet connection.
