    • Bullet Points:
    • Heat Pumps can deliver 90 °C Heat
    • 90°C Heat can drive a desalination process
    • This are proven technologies
    • District Cooling is a viable heat source for desalination delivering 40% savings in water cost
    DISTRICT COOLING & DESALINATION USING HEATPUMPS & M.E.D.
  • DISTRICT COOLING & DESALINATION USING HEATPUMPS & M.E.D. David Pearson Director of Innovation Star Refrigeration Imtiaz Khan Regional Manager, Energy (Power, Oil & Gas) Alfa Laval Middle East Ltd
  • The future……………. Stephen Appleton, Director Ramboll 2010
    • "The three issues which will have the greatest impact on humanity over the next century are Climate Change, Energy Security & Water.
    • Not only is water becoming a scarce resource, but carbon emissions due to countless air conditioning systems, are having a significant impact on climate change. The electrical load associated with hundreds of thousands of air conditioning units is also putting a strain on energy supplies and hence greater risks associated with energy security.
  • Some “unusual” Solutions to a Real problem
  • Think Differently-District Cooling and Desalination
    • A solution to this would be through the use of ammonia refrigeration heat pumps serving district cooling networks, with waste heat being utilised for desalination purposes.“
    • Stephen Appleton, Director Ramboll 2010
    • 1954 Pioneer with first Desalination unit onboard a ship – shell & tube design
    • 1967 Design with Titanium plates as evaporator heat transfer surface
    • Today
    • Supplied more than 30,000 units of the plate desalination concept
    • More than 850,000 m 3 /d in accumulated capacity
    • Average 1000 units per year is delivered
    • Market share leader with 70 % market share achieved and sustained for marine and offshore
    History & Experience Marine Applications Desalination Milestones
    • Does the NeatDesal technology exist?
    • 1988 Decision to Develop a plate desalination concept for large scale capacities
    • 1992 Commercial introduction of the Titanium plate desalination concept
    • Received orders for more than 200 new plate type desalination units.
    • More than 100,000 m 3 /d capacity installed
    • With successful implementation of the concept, significant number of references has been achieved in all parts of the World
    History & Experience Land Applications Desalination Milestones
  • Example of desalination installation References Round the Globe World wide Alfa Laval Experience

  • Kansai Electric (KEPCO), Nuclear Power Plant, Takahama, Japan; 2x TVC-4-1000; 2x 1,000 m3/day, 2002
  • High quality water for Prawn production National Prawn, Saudi Arabia MED-5-425 - 475 m 3 /day 2002
  • Binzagr CO-RO produce soft drinks and beverages using freshwater distillated from underground water, which has a higher salinity chemical complexity than the Red Sea Binzagr CoRo, Jeddah, VVC-350 & VVC-125: 475 m 3 /day
  • Steam or hot water SG MEP Process
  • Corrugated plate design promotes High turbulence with
    • Efficient heat transfer
      • 3-5 times higher in liquid/liquid applications
      • 2-3 times higher in 2-phase applications
    • Minimised fouling
      • 5-10 times higher wall shear stress
    Hot Medium Cold Medium Plate heat Exchanger (PHE) Channel design
  • Multiple Effect Process
    • Vessel Internal: - Pressure Plate - Plate Pack
    • Sea Water distribution
    Multiple Effect Process
  • Plate type Tubular Performance % 1 2 125 100 75 Time Performance through time Alfa Laval Plate type evaporators can be cleaned 100% Tubular evaporators gradually decrease performance because of “irreversible” scaling/fouling CIP cleaning can remove alkaline soft scaling, and hard scaling can also be removed 100% in a PHE type desalination unit. Why use Plate MED?
  • Think Differently-District Cooling and Desalination
  • How do we “Raise“ heat from 2C to 90C? Interstage @ 58C HOR = 14.05MW R eff = 9.61MW COPh = 3.16
  • 90 ˚C Ammonia Heatpump
  • The World’s Largest 90C Natural Heatpump?
  • District Cooling and Desalination
      • Solution?
      • Use waste heat from cooling plant.
    Typical District Cooling COPc = 4.0 10MW Cooling 2.5MW Power 12.5MW Waste Heat Combined DC and Desalination COPc = 2.0 10MW Cooling 5.0MW Power (extra 2.5MW) 15MW Waste Heat Incremental COPh = 15/2.5 =6.0 “ Free” waste heat from Power plants is without this energy cost BUT, Power plants are not as convenient an energy source as District Cooling.
