The Benefit of
Uniting Ground Power
and Conditioned Air
Guinault's GF15 Combo model combines the functions of a GPU and ACU
into one unit designed to lower emissions and operating costs.
W
hen ground support equipment (GSE) with electric
motors or diesel engines can be utilized to
power and cool aircraft on the ground, it allows
the plane's auxiliary power unit (APU) to be turned off.
With less jet fuel being consumed at the gate, environmental
factors and airlines' operating costs improve.
To assist with this, Guinault has developed a combination
air conditioning unit (ACU) and ground power unit (GPU). The
G15 ACU/GPU combines the advantages of an air conditioner
and generator and benefits from the technical developments
Guinault has achieved over a timespan of more than 60 years.
According to Lionel Clermont, Guinault's president and
CEO, GPUs for decades have been a primary energy source for
aircraft on the ground and air start units (ASUs) have been
necessary only in the case of an APU failure. ACUs have been
viewed as an option, in hot weather.
Today, Clermont says that's changing.
" ACU is becoming mandatory, together with the GPU, and in
certain cases ASU, as we are looking for a substitution to the
APU, " he says.
" Having the GPU and ACU combined in a single unit
appears to make sense, as both functions are simultaneously
required in most of the cases, " Clermont says, noting

the combination offers operation savings for fuel, handling
and maintenance. " The expertise of Guinault in electronics,
alternators and thermodynamics was the necessary tool to
make it right. "
The ACU/GPU combo provides aircraft power (400 Hz or
28 VDC) and aircraft air conditioning -- either separately or
simultaneously.
The ACU maintains the correct temperature in the cockpit
and cabin during pre-flight operations, boarding and
maintenance. The unit adapts its flow and cooling power to
a variety of aircraft types, weather conditions and airline
requirements in terms of cabin temperature and ventilation.
It also helps meet the needs and requirements of code B and
C civil aircraft in continental, tropical or desert climates.
Lastly, the ACU dehumidifies the air to avoid frost in the
heat exchanger.
While the idea of having a combo unit is not new, Clermont
says this unit is notable because of the dual voltage alternator.
" The concept does not require any sensitive and complex
frequency converter, is easier to maintain and is more reliable, "
says Clermont, noting the Guinault combo unit entered
the market in 2016 and was improved in 2019 with a more
efficient cooling concept.
