  1. Cristopia (CIAT) - energy savings systems in air conditioning

  2. CRISTOPIAEnergy Systems • Developed an original energy storage system in 1982 • Became a subsidary of CIAT in January 1988 • LOCATION • Head office & factory in Vence (French Riviera) • French Commercial Office located near Paris • Asian Office in Kuala Lumpur (Malaysia) • WORLD-WIDE REPRESENTATION • Distributors of CRISTOPIA technology in more than 25 countries • LICENCE AGREEMENTS • in Japan : Mitsubishi Corporation • in South Korea : D.I. Corporation • in India : Cristopia Energy Systems India Private Ltd. (Joint Venture) • in China : Hangzhou CIAT Refrigeration Equipments Co. Ltd More than 500 references in 25 countries 2.5 millions of kWh daily shifted 150 MWe saved

  3. BASICS OFTHERMAL ENERGY STORAGE

  4. WHY STORE ENERGY ? • to size a chiller to satisfy the average load instead of the maximum load (few hours per day or even per year) • the chiller runs on a continuous basis • to increase plant capacity • to increase system reliability (back-up) • to increase system efficiency (no short cycle) • to protect the environment : • reduce CO2 emissions • limit the use of CFC's or HCFC's • for energy management (off-peak electricity period) • to reduce system operating costs

  5. TRADITIONAL SOLUTION STL SOLUTION Reduced Installed Capacity

  6. Energy managementbyCRISTOPIA Thermal Energy Storage • Reduce • chiller size by 30 to 70% • use of refrigerant by 50 to 80% • cooling tower installation • space for plant • maintenance • running cost • CO2 emissions • Increase • cooling capacity from existing chiller • plant utilization • equipment life • Additional benefits • avail yourself to a back-up system • shift cooling load from peak hours to off-peak period

  7. APPLICATIONFIELDS AIR CONDITIONING • Office buildings • Hotels • Hospitals • Banks • Conference centres • Computer rooms • Airports • Clean rooms • Supermarkets • Sports centres • Theatres, cinemas, TV studios

  8. APPLICATIONFIELDS INDUSTRIAL PROCESS COOLING • Dairy and food industries • Bottling plants • Slaughter houses • Meat industries • Cold storage • Central kitchens • Breweries • Laboratories • Pharmaceutical industries • Chemical plants • Refineries • Computing rooms

  9. CRISTOPIALATENT HEAT STORAGESTL FOR : • AIR CONDITIONING • INDUSTRIAL APPLICATIONS For a better management and use of electricity

  10. STL SYSTEM • 2 elements • tank • (made to measure according to site requirement) • nodules

  11. THE NODULE • Polyolefines material : chemically neutral towards eutectics and heat transfer fluid • Controlled thickness : no migration of the heat transfer fluid • Cap ultrasonically welded • External diameter : 77 & 78 mm .. Industrial cooling 98 mm ……... Air Conditioning • Heat exchange surface • 77 & 78 mm : .... 1 m2/kWh stored • 98 mm : ……... 0.8 m2/kWh stored • Useful number of nodules per m3 • 77 mm : ... appr. 2 548 • 78 mm : ... appr. 2 444 • 98 mm : ... appr. 1 222

  12. TESTS of the PRODUCT • CEA PCM ageing • ECOLE des MINES de PARIS Nodule mechanical strength • CETIAT STL thermal performances • COSTIC STL thermal performances • CSTB STL durability

  13. OPERATING PRINCIPLES CHARGE MODE

  14. OPERATING PRINCIPLES DISCHARGEMODEPartial Storage

  15. ADVANTAGES of the STL • Reliable system manufactured automatically with a high level quality control • Storage temperatures adapted to usage (from -33°C to +27°C) • Static system • maximum reliability • no risk of breakdown • no maintenance • Closed system with high service pressures allowed • Adaptability to site • Optimized time to store due to a high exchange surface • High cooling capacity • Eco-friendly system • Large know-how based on more than 16 years of experience More than 500 references worldwide

  16. CRISTOPIA Energy Systems Airport, bank, hospital, office building, department store, central kitchen, computer room, food industry, dairy industry,...

  17. CONCLUSION • Technical • reduction of installed chiller capacity • reduction of short-cycling • increase in system efficiency and reliability • simplified maintenance • flexible system • Environmental • limitation of the use of CFC's or HCFC's • reduction of CO2 emissions • saving of up to 15 % of energy due to a better energy management • Financial • shifting of kWh from day to night • saving on the maximum demand charges • energy saving
