An example of Véolia Energies Research the use
of ice slurry on District Cooling Networks

• Veolia Energie operates several District Cooling
  Networks (DCN) in the world
• Some DCN are no longer sufficient to meet a
  growing cooling demand, especially in urban areas
• A solution the use of ice slurry instead of
  chilled water in the pipes of the network

10
An example of Véolia Energies Research the use
of ice slurry on District Cooling Networks

• What is ice slurry?
• It is an aqueous solution that contains ice in
  the form of microscopic crystals
• Advantage of ice slurry?
• It carries a greater amount of energy through
  pipes than chilled water it can be a response to
  the problem raised by the saturation of
  distribution system

11
An example of Véolia Energies Research the use
of ice slurry on District Cooling Networks

• Assess ice slurry as a secondary refrigerant in
  our DCNs
• Evaluation on a test loop of the service
  requirements for ice slurry (segregation,
  clogging, abrasion phenomena attributable to the
  presence of ice in the liquid phase)
• Solutions for the metering and the production of
  the slurry
