3.5 Innovative technologies
Inverter technology
The scroll compressor not only works in on/off mode,
but is operated with power control (modulating, accor-
ding to the current power requirement).
Advantage:
–
Precise power adjustment.
–
Increased efficiency through reduced clocking.
–
Quieter operation on average due to reduced speed
in the partial load range.
–
Reduction of the power of secondary drives (fan,
primary circuit pump)
Intermediate steam injection
In the scroll compressor, wet steam is injected from
the economizer heat exchanger for cooling.
Enhanced Vapourized Injection injection increases
efficiency, while the power requirement is reduced at
the same time. Thus higher flow temperatures and
higher heating output (especially at low outside tempe-
ratures) are possible. The compression temperature
decreases, increasing the life expectancy of the
compressor.
