CO 2 – the natural refrigerant for MT and LT in discounters, supermarkets and hypermarkets October 19, 2009 Bernd Heinbokel

think system, master energy 2 AGENDA Comparison of refrigerants Overview on subcritical LT cascade systems Overview on transcritical MT systems Comparison of energy efficiency Conclusion

think system, master energy 3 REFRIGERANT OVERVIEW EU, Mobile air conditioning: 2011: Ban in new car types 2017: Ban in all new cars

think system, master energy 4 HFO1234yf AND HFO1234ze ARE … ??? Flammability according EC Directives 67/548/EEC, safety data sheet: Extremely flammable R12, F+ Use only in explosion proof systems and areas Expected classification according DIN EN 378:2008 due to published data: Low flammability, not toxic, safety class A2 Charge limitation Use in multi compressor units with direct expansion would not be possible!

think system, master energy 5 WHY CO 2 AS REFRIGERANT? CO 2 (R744) is... A natural substance A by-product of the air separation process A climate neutral refrigerant No ozone depletion potential No disposal necessary Classified as non-toxic As carbonic acid contained in many beverages Cost effective and worldwide available

think system, master energy 6 WHY CO 2 AS REFRIGERANT? CO 2 (R744) is... A good heat transfer fluid 4 to 6 times higher volumetric efficiency Designed for the future No taxes on GWP No filling charge limitation Best in class refrigerant for heat reclaim

think system, master energy 7 WHY CO 2 AS REFRIGERANT? CO 2 -subcritical: approx. 3 times higher heat reclaim capacity to heat-up tap water compared to R404A or R134a Heat reclaim in MT-multi compressor systems Refrigerating capacity 100kW, to=-10°C, CO 2 =-8°C, superheat 8K, sub cooling 5K Desuperheating to 30°C, tap water approx °C

think system, master energy 8 WHY NATURAL REFRIGERANTS? TEWI comparison for the supermarket format Data according German climate conditions

think system, master energy 9 WHY NATURAL REFRIGERANTS? CO 2 in comparison to R404A ~10% savings in energy consumption * Car with 0,12kg CO2/km ; km per year Average savings in North-Europe / Leakage rates: Hyper 15%, Super 12%, Discount 8%

think system, master energy 11 SYSTEMS FOR LT Subcritical in cascade to MT or as Booster kW LT-refrigerating capacity in 170 stores CO 2 -LT got standard for example in: Scandinavian countries, Switzerland Several German retailer chains

think system, master energy 12 TIMELINE AND OUTLOOK in the retail business

think system, master energy 13 DX-SYSTEMS For medium temperature, transcritical kW refrigerating capacity in 90 stores, additional 20 stores ordered Norway 9 stores Sweden1 store Denmark28 stores UK3 stores Germany24 stores Netherlands1 store Czech Republic2 stores Hungary1 store Luxembourg1 store Austria1 store Switzerland19 stores

think system, master energy 14 RISKS BY HIGH PRESSURE LEVEL Pressure multiplied by volume as parameter for risk by overpressure is not higher than in R4040A- or R134a-DX-systems, while having significantly lower filling charges.

think system, master energy 15 CO 2 – DIRECT EXPANSION For MT- and LT refrigeration Cascade Booster Higher energy efficiency Smaller rack footprint Lower installation costs

think system, master energy 16 COMPARISON OF ENERGY EFFICIENCY R404A, R134a and CO2-DX in MT-supermarket application Bad COPAverage COPGood COP Design condition Annual average temp. Annual hours [h] tA Ambient temperature [°C] R404A CO 2 R134a CO 2 is efficient in Supermarket refrigeration at average ambient temperatures R134a is efficient in air conditioning at high ambient temperatures Attractive energy savings can be obtained with average annual temperatures up to 15 °C. For example: Stockholm 7 °C, Brussels 10 °C, Paris 12 °C, Milan 13 °C, Madrid 14 °C Carrier has the right refrigerant solution for every application, but every application will not have the same refrigerant solution.”
