  12. 12. REFRIGERATION SYSTEMENVIRONMENTAL IMPACTTEWI Total Equivalent Warming Impact, is considered asa good parameter to evaluate the impact on the environmentcaused by a refrigerating system.Direct effect:L – Leakage rate (kg/year)n – Life time (years)m – Refrigerant charge (kg)– Recycling factor (%)Indirect effect:E – Energy consumption (kWh/year)– Emission from energy generation(kgCO2/kWh)TEWI = GWP*L*n + GWP*m*(1- ) + n*E* [kg CO2]
