- The global warming potential (GWP) was evaluated through a
100-year time span.
-The LCA study concentrates only on the values that differ
between the different diffuser design scenarios. Thus, the main
differences are in the amount of aluminum sheet needed to
manufacture the diffuser in Scenarios 0–3 as well as the annual
electricity consumption during the compressor’s use phase.
-The varying electricity consumption when machining the diffusers
is taken into account.
-The other parts in the studied compressor remain the same;
thus, they are excluded from the study.
-There is no difference between the service life and the maintenance
needs of the compressors in Scenarios 0–3, and therefore
they are not taken into account.
-The waste treatment of the diffuser is excluded, as the focus of
this study is on the production and use phases.
-Transporting the aluminum sheet to the diffuser manufacturing
as well as transporting the diffuser to the location of use is
excluded because the transported masses are negligible in the
case of only one diffuser
