Fugitive Emissions Split System Air Conditioners
The Search for End of Life Refrigerant 64% of the installed bank is in Air Conditioners - kg Split System AC 80% of installed equipment - units Fun Fact 13.5 Million Split System installed in Australia 1 Split system for every 2 people No factual data on charge sizes Leakage rates operational longevity So we developed a study
Year of Manufacture & Year of De-installation Refrigerant Type Initial Charge Size End of Life Charge Size (Recovered amount)
Refrigerant Type 58, 5% Total iterations = 1152 600, 52% 494, 43% R22 R410A R32
2.5 2.0 1.5 1.0 0.5 0.0 R22 R410A R32 Initial Average Charge Size In Kilograms Overall = 1.93
Year of Installation Average age at replacement = 13.7 years 100 90 80 70 60 50 40 30 20 10 0
Range of Refrigerant Loss 250 50% of units lost less than 20% of charge 200 150 100 50 0
R32 78.8 21.2 Retention and Loss % R22 71.9 28.1 Average loss at EOL = 30% R410A 68.3 31.7 0.0 20.0 40.0 60.0 80.0 100.0 Retained Lost
Summary of Fugitive Emissions Fugitive Emissions 0.87 million CO2e annually Split AC installed base of 13,500,000 units Average life 13.7 years - retirement rate 7.3% Average initial charge size 1.93 kgs Average charge at EOL 1.33 kgs Average loss through service of 30%
