Agenda • Global Warming Potential vs Global warming Impact • Containment • Monitoring
What is Global Warming Potential (GWP)? Global Warming Impact ignored • GWP = f (Atmospheric Lifetime – LA, Radiative characteristics) • GWP Absolute = Radiative Effect accumulated over the full LA; (mW.yr.m-2.ppm-1) • GWP Relative = Radiative Effect accumulated over a fixed period relative to the radiative effect of a reference substance • Reference Period = 100 years (by convention) • Reference Substance = CO2 The Absolute GWP of CO2 The reference period of 100 years is unfavourable for shorter lived substances
What really matters is the Warming Impact • Warming Impact = [f (GWPA, emissions )] • Emissions = f (tightness, charge) • Consequently, the emission levels are crucial: • Tightness • Charge • Look at the interdependencies (TEWI) • Energy Efficiency of the system • Emissions
Critical Issue: Containment • All measures technically and economically feasible to prevent emissions • Design of equipment => CE marking • Quality of material, connections, installation =>Certified Personnel • Operating Conditions: Vibration, corrosion, degradation of materials • Preventive maintenance • Frequent leak-inspections >3 kg annually; >30 kg quarterly; >300 kg monthly • Accessibility of equipment • Energy Efficiency will be main driver • Charge loss means greater power consumption • Focus on total system performance: e.g. clean heat exchangers • Exemptions possible when leakage detection systems are in place (mandatory for > 300 kg) • Potential conflict with ventilation/safety requirements (EN 378) Smaller charges and tighter circuits
Critical Issue: Monitoring • Purpose of Monitoring: • Adequate data on actual emissions • Tool for operators of equipment • Actual power consumption may be more effective • Data need to drive actions • Monitoring through: • Log Books for installations • Charge and type of Refrigerant used • Quantities recovered and added • Verification of Qualifications • Data reporting by Producers and Importers: • Incomplete picture because it does not cover the complete supply chain • Trade in Equipment containing F-gases? Monitoring is Necessary but not Sufficient
