What is COP?
An air conditioner's COP (coefficient of performance) indicates how
efficiently it uses energy. A high COP means high energy efficiency.
COP =
Capacity (W)
Power consumption (W)
High energy savings
Daikin energy-saving technologies
Pulse Amplitude Modulation (PAM) control
reduces energy loss by controlling the amount
of switching on/off of the converter.

Swing compressor
Reluctance DC motor
PAM control
The swing compressor can reduce
operational vibration and sound
because its piston moves smoothly
inside the compressor.

This marked the development
of a high-performance swing
compressor that was
compatible with alternative
fluorocarbons. The prize was
presented in 1997.
Reluctance DC motor
Swing compressor
Thanks to its smooth
rotation, the swing
compressor decreases
friction and vibration. It also
prevents the leakage of
refrigerant gas during
compression. These
advantages provide quiet
and efficient operation.
Daikin DC Inverter models are
equipped with the Reluctance DC motor
for compressor. The Reluctance DC
motor uses 2 different types of torque,
neodymium magnet*
1
and reluctance
torque*
2
. This motor can save energy
because it generates more power with
a smaller electric power than an AC or
conventional DC motor.
*1. A neodymium magnet is approximately 10 times stronger than a standard ferrite magnet.
*2. The torque created by the change in power between the iron and magnet parts.
Note: Data are based on studies conducted under
controlled conditions at a Daikin laboratory.
This was the first scroll
compressor to be equipped
with the Reluctance DC motor
in commercial-use air
conditioners. The Institute of
Electrical Engineers of Japan
presented the award in 1998.
Neodymium magnets are used
in the pink-coloured area.

SUPER MULTI HW offers a more powerful outdoor unit to families living in HDB apartments with a limited current of 8.5 A or 11 A.
Note: Please direct enquiries to local dealers.
A quiet outdoor unit is essential for your comfort and peace in your neighbourhood. Super Multi HW achieves
a quiet sound level of 45 dB (A) during Outdoor Unit Quiet Operation of the 3MWKS80K.
A quiet indoor unit is important for your personal comfort.
Super Multi HW offers the quiet sound level of 22 dB (A)
during Indoor Unit Quiet Operation of the FTKS25D.
Note: Capacity may decrease when quiet functions are selected.
