  • case study: turkey ๏ Montreal Protocol: Turkey operates under Article 5 - is legally required to phase out ODS by 2010 ๏ good track record on ODS so far: Turkey received MP award as one of the 9 most successful Article 5 countries in implementing the treaty ๏ Kyoto Protocol : Turkey signed only recently (Feb 2009) -is not an Annex B country (not obliged to reduce GHG emissions to 1990 levels between 2008- 2012) ๏ among all Annex I countries,Turkey has the highest rate of increase in GHG since 1990 (82 %), is the 24th largest carbon emitting country in the world 14
  • case study: bahçelievler carrefour ๏ retailer: Carrefour group - Carrefour Sabancı Ticaret Merkezi A.Ş., ๏ store location: Istanbul, Turkey ๏ store opening: August 2009 ๏ working hours: 10:00 am - 10:00 pm ๏ sales area: 7,778 m2 15
  • system type & layout ๏ CO2-R404 cascade system ๏ LT refrigeration: CO2 ๏ MT refrigeration: R404a ๏ involved partners: ๏ commission/installation: Cözüm Soğutma ๏ CO2 system design: enEX ๏ CO2 compressors: Dorin (CETINEL) ๏ system management: CAREL 16
  • store layout & location of system ๏ CO2 in deep-freeze zones and one island refrigeration system 17
  • motivation for switch - overview ๏ technology: feasibility, replacement potential to HCFCs ๏ market: availability, penetration rates, expertise, personnel ๏ environment: ODP, GWP, direct emissions, energy savings ๏ costs: system, installation, operation, maintenance, end-of- life ๏ safety: reliability, use restrictions, safety regulation 18
  • motivation: technology ๏ CO2 cascade systems one of the most consolidated solutions ๏ standardised system and component solutions developed ๏ no major technical challenges left ๏ CO2 has established itself as a preferred cooling fluid in LT ๏ Carrefour: undertook a diagnosis of its refrigeration equipment and leakage rates and decided for climate-friendly refrigeration systems in new stores - as replacement for obsolete systems 19
  • impact: technology ๏ system uses copper pipes resisting higher pressure ๏ CO2 has a higher volumetric refrigeration capacity than R404a and needs a significantly smaller pipe diameter ๏ CO2 compressor for cascade system has significantly smaller dimensions and motor size than comparable R404a DX model 20
  • motivation: market ๏ CO2 cascade systems widely available in Europe: several thousands in Denmark, Scandinavia, Switzerland, Austria, Germany, UK - now starting in Canada, USA ๏ gained expertise from developed countries can be used by developing countries and markets not familiar with the systems ๏ components availability and expertise constantly growing ๏ Carrefour: market penetration of CO2 commercial refrigeration further accelerated with more widely available qualified contractors. Relevant for countries outside the EU, and more particularly in Asia and Latin America 21
  • motivation: environment ๏ CO2 cascade system eliminates presence of HCFCs and largely reduces HFC use throughout the entire installation ๏ CO2 occurs naturally, ODP = 0, a GWP = 1 ๏ direct emissions: reduced significantly ๏ indirect emissions / energy use: in cascade solutions in warm climates a highly energy-efficient solution ๏ Carrefour: GHG emissions control is taking priority in the construction of food retail stores worldwide. Carrefour needs to retrofit up to 700 stores by 2015 with 500 tones of R22 22
  • motivation: environment ๏ Carrefour: “HFC is not a sustainable technology solution in the long term” and it will be used “only if there are no other technically feasible, secure, low-cost and environmentally friendly solutions” to HCFCs ๏ Carrefour supports “the technical developments with natural fluids and hydrocarbons” ๏ Carrefour: where F-gases are still used - as in this case - leakages must be reduced as much as possible with a stricter containment policy 23
  • impact: energy use ๏ refrigeration systems take the largest share of energy consumption in Carrefour stores up to a floor size of 2500 m2 ๏ baseline: 2004 for 25% less energy consumption by 2020 ๏ CO2 cascade system is up to 40% more energy-efficient than comparable system used before (saving: 41,659.20 kW/year) ๏ result: several markets already 24
  • motivation: costs ๏ standardisation of systems and components has reduced price for system design, installation, maintenance ๏ serial production and wider adoption in more world markets will bring down costs again ๏ higher prices of chemical refrigerants and expected cost from F- gases legislation make systems still more cost-competitive ๏ Carrefour: decided to invest in CO2 cascade systems because they have become more affordable & make sense for an investor. 10 stores in France, Belgium, Italy, and Turkey have already been retrofitted to CO2 refrigeration - up to 700 25
  • impact: costs ๏ CO2 installation: similar costs as HFC-only system ๏ further cost reduction expected with more market demand & economies of scale ๏ compressor: CO2 model 6 times less expensive than R404a equivalent ๏ operation: savings of 4,700 USD/year from energy bill alone (compared to system used before) ๏ maintenance: similar costs as HFC-only system; no maintenance in 10 months needed 26
  • motivation: safety ๏ cascade systems with only natural refrigerants available: CO2- ammonia, CO2-hydrocarbons ๏ all natural refrigerants have been proven to work safely and reliably when following established safety guidelines ๏ challenge: non-harmonised safety regulation and standards as regards the use of flammable and toxic substances ๏ Carrefour: decided for an R404 cascade system due to the inconsistent use of safety standards regarding ammonia and hydrocarbons as refrigerants 27
  • impact: safety & reliability ๏ commission & installation of CO2 refrigeration systems carried out without major issues ๏ lack of technicians experienced with high-pressure CO2 system still poses a barrier to wide-spread use ๏ cascade system has been running without any need for maintenance/repair for 10 months with high reliability 28
