      • TOU01 - Thermoliner

          • Cruise liners need a huge quantity of energy to heat or to cool their facilities (fitness rooms, swimming pool, spa, guests rooms, restaurant, bars, shops, etc.). They generally use aero-thermal heat pumps. Aero-thermal HP efficiency is directly related to the out-door temperature. The average efficiency (COP) of a HP is around 4. (i.e. 4 thermal kWh produced for 1 electrical kWh consummated).
            Providing HP with ideal stable temperature, we increase its efficiency and save energy consumption. Therefore, HP COP increases up to 50%.

            In the sea, at a depth of 10-15 m, temperature is stable around 5°C to 15°C depending on the latitude and the season. Our idea is to provide 
            cruise liners with natural sea temperature. The system would consist on a large tube (1000 m +) of clear water (not sea water to avoid maintenance hazard) pulled behind a liner to supply onboarded heat pumps (HP) with stabilized temperature (5°C - 15°C).

            This system will enable onboarded HP to enhance their performance coefficient (COP).  Another issue is to evaluate photovoltaic capacity during the trip and correlate with sea temperature (and the onboarded HP electrical needs).

            Our challenge consist in getting thermal and solar radiation data on cruise liners regular lines, at different seasons, to model energy capacity of each cuise liner trip. With these data, we will be in capacity to propose an energy saved evaluation.
