Sea Water Air Conditioning - SWAC
AIR CONDITIONING FROM WORLDWIDE COLD WATERS, LAKES & OCEANS
Sea Water Air Conditioning (SWAC) is a proven technology using the deep cold water of the oceans to provide cooling solutions to coastal buildings & communities. The cold water is pumped through heat exchangers, that generate cold to be transferred through a closed circuit to any of the facilities connected. SWAC provides up to 90% savings on conventional AC units related electricity costs!
It can be used for hotels & resorts, isolated communities, government & military facilities, large commercial & industrial complexes, universities, airports, and data-centers. SWAC can be installed anywhere close to the infinite free resource of Oceans, Lakes & Rivers.
BARDOT Ocean’s SWAC technology uses pumps to bring in large volumes of deep cold water to feed the heat exchangers of the system, that generate a cold source. The cold water (4-7°C) is pumped up from depths of 700 to 1000m, depending on the temperature pattern of the water source.
The exchangers, located on-shore, will use the cold temperature of the deep sea water to cool down a completely independent circuit that will generate the cold distribution to the facilities.
Used water is then sent back to the ocean, at depths corresponding to its temperature, to avoid any environmental impact. A part of this water can be used to produce fresh water through a Sea Water Reverse Osmosis (SWRO) system, that can provide drinkable water, and water for agriculture and aquaculture.
The key of success of SWAC is the capacity to access deep cold water very close to the installation.
A robust and field proven process, designed for reliability and continuous cold supply:
1 - Cold water intake pipe, may go down to 1000m depth, to reach down to 4°C.
2 - Water rejection pipe, at specific depths to eliminate environmental impact due to temperature difference.
3 - Pumps, for large volumes of water, designed to consume the minimum energy to operate.
4 - Heat exchangers made of titanium.
Bardot Group has developed an innovative and efficient full EPCI solution, based on our highly skilled engineers that deliver complete studies and design for a fit for purpose solution. Among which:
High density polyethylene (HDPE) pipes
Adapted ballast according to bathymetry
Sea water pump
Thanks to various manufacturing sites worldwide, Bardot Group is able to produce SWAC solutions close to where it is requested and helps you optimise your local content and project logistic. Our expertise in composite manufacturing allows us to reach custom-made solution and flawless product quality, to deliver timely the best product to our clients.
Bardot Group’s SWAC systems are designed according to the sea bed particularities. Different ballasts will be designed to adapt our system. A custom made Installation procedure is provided for each SWAC project to ensure the proper assembly of your system. Calculations for the installation are performed by our engineers to validate our installation procedure.
Our engineers are also available for training and on-site monitoring of the installation, with the sole purpose of providing maximum support to our client.
Features of BARDOT Ocean's SWAC:
Custom made design: Sea Water Air Conditioning systems are designed to fit your requirements of water depth, temperature, flow rate, temperature and to accommodate the hydrodynamic stress of your operation environment.
Long-lasting: Materials used have been selected for their good behavior over time. Our design conservatively considers end of life properties, and guarantees that no maintenance will be necessary.
Light structure: The low weight design facilitates installation.
Modular strapping system: Our wide range of strapping systems provides adapted solutions to fit with your environmental loads and project life.
Environmental Management will be main priority of the project.
