What influences GWP?
When entering the atmosphere through leakage, a refrigerant influences the global warming by its potential to reflect radiative heat from the earth. This potential is influenced by the molecular structure as well as its lifetime in the atmosphere and is referenced to a natural substance (CO2).
However, fossil fuels are used to power reefers on a vessel and CO2 emitted into the atmosphere also has an impact on global warming. Inefficient systems use more energy and thus generate more CO2. TEWI combines the emissions of both refrigerant and power consumption.
Total Equivalent Warming Impact
The Total Equivalent Warming Impact (TEWI) is a measure that combines the impact from direct and indirect emissions and gives a more holistic picture than a simple GWP comparison.
In particular, TEWI enables the comparison of efficiency of different refrigerant options in a specific application. For reefers, the real annual operation profile is taken into account, as they are operated mostly in hot climates and environments.
R513A is the pragmatic replacement for R134a, offering high energy efficiency and low GWP.
