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)

The swing compressor can reduce
operational vibration and sound
because its piston moves smoothly
inside the compressor.

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.
The use of a Reluctance DC motor with
neodymium magnets
*1
for our
compressors has improved motor
efficiency by more than 20% compared
to AC motors. The high torque
*2 and
stronger magnetic force produced is
beneficial particularly at low load
conditions.
*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.
Neodymium magnets are used
in the pink-coloured area.

Non-inverter air conditioners can
only perform simple on/off
operation. They start operation
when the temperature rises and
stop when the room reaches the
set temperature and then switch to
low-capacity operation. As a result,
inverter air conditioners are more
energy efficient and comfortable
than non-inverter air conditioners.

With Super Multi NX, cooling operation is possible even during lower
outdoor temperatures.
Note: This information is for heat pump type.
Super Multi NX achieves a quiet sound level of 43 dB (A) during Outdoor Unit Quiet Operation or Night Quiet
Mode of the 3MXS52 during cooling operation.
Note: Capacity may decrease when quiet functions are selected.
Super Multi NX offers the quiet sound level of 22 dB (A) during
Indoor Unit Quiet Operation of the FTXS20/25 during cooling
operation.
Note: Capacity may decrease when quiet functions are selected.
