High external static pressure, 1 phase.
A COLLECTION OF CUTTING EDGE TECHNOLOGIES
COMBINED TO ACHIEVE IMPROVED EFFICIENCY
AND QUIETER OPERATION
1 Cutting edge Compressor Technology
SCROLL COMPRESSOR
Optimum energy saving performance and
quieter operation are made possible by
reducing overheating losses.
SWING COMPRESSOR
Energy savings are made possible by eliminating leakage
of refrigerant and a significant reduction in friction.
Powerful magnets –
Use of neodymium magnets in the motor
enables efficient generation of high torque,
reducing the size of the compressor.
Smooth sine wave DC inverter –
Use of the optimised sine wave smoothes motor
rotation, further improving operating efficiency.

FEATURES OF NEW DAIKIN INVERTER
DUCTED SYSTEMS
• Requiresonlysinglephasepowersupplywhichcanlower
installation costs.
• Quietyetpowerfuloperation.
• Hotstart.Intheheatingmodeandafterdefrost,
the indoor heat exchanger is warmed up to a preset
temperature first before the indoor fan switches to the set
fan speed. This ensures that only warm air is discharged
from the air conditioning unit.
• BuilttoexceedcompliancewithrelevantAS/NZS
standards.
• UtiliseDaikin’sproprietaryelectroniccontrolsystem,for
more precise control.
• Compactdesignofindoorunitsallowsinstallationinto
limited roof spaces.
• Indoorunitscanbedismantledforeasierinstallationinto
confined roof spaces.
• Nightquietmodereducesthesoundlevelsoftheoutdoor

except FDYQ50/60).
• Certiedoperationdownto-15˚Cinheatingandupto
46˚C in cooling.
• PEcoatedheatexchangersforgreaterprotectionagainst

2 Smooth Air Inlet Bell Mouth
and Aero Spiral Fan –
These two features work to
significantly reduce noise. Guides
are added to the bell mouth intake
to reduce turbulence in the airflow
generated by fan suction. The
aero spiral fan features fan blades
with the bent blade edges, further
reducing turbulence.
3 DC Fan Motor –
Efficiency improved in
all areas compared to
conventional AC motors,
especially at low speeds.
(Outdoor unit)
4 Super Aero Grille –
Refined ventilation mechanism enables further reduction
in required fan power. Resulting in greater energy savings.
Note: Data are based on
studies conducted
under controlled
conditions at a
Daikin laboratory.
