The Comparison, Measuring & Labelling of Energy-efficient Textile Machinery
The figure illustrates an example of the balance envelopes
of cases b), c) and d).
figuratively speaking, a hallmark of
German textile machinery production.
The industry sees the most important
levers for development and innovation
in the further development of textile
technologies and processes and
technical control and design measures.
energy-efficient components and
materials make further contributions.
Principles of energy efficiency –
assessment of textile machinery
Basic model, balance envelope
The choice of an appropriate balance
envelope is crucial for an energy
balance study. Machines or processes
can only be compared and analysed
with defined balance envelopes and
benchmarks. Depending on the
purpose for which energy consumption
is analysed, one of the following
“envelopes” can be needed for an
energy balance :a) A machine section
b) A complete machine
c) A production chain consisting of
individual machines and the
intervening processes (e.g.
transport)
d) An entire production facility
including the forms of energy
required for air conditioning and
lighting
e) An entire product manufacturing
process or a par t of the
manufacturing process located at
various facilities including the
transport between the production
sites.
