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 (kW)
Power consumption (kW)
* During rated capacity operation of 4 indoor units
(2.0 + 2.5 + 5.0 + 5.0 kW class).

The reluctance DC motor is much more
efficient than conventional AC and DC
motors. Its advanced design has
improved low-capacity
operation by more
than 20%.
The swing compressor decreases friction
and vibration and also prevents the
leakage of refrigerant gas
during compression.
This gives much quieter
and more efficient
operation.
Pulse Amplitude Modulation (PAM) control
reduces energy loss by controlling the amount
of switching on/off of the converter.
Neodymium magnet
The reluctance DC motor employs
neodymium magnets. These magnets
are approximately 10 times stronger
than ferrite magnets.
Neodymium magnet Ferrite magnet
Energy efficiency is increased by reducing
operational friction and refrigerant gas leakage.

DC inverter power control uses its
full capacity at startup to cool/warm
quickly. As soon as the set
temperature is reached, it carefully
adjusts current frequency to
prevent temperature fluctuation and
energy loss.

Even during a cold season, a crowded party or a sudden change in the
indoor temperature can leave a room overheated. With SUPER MULTI NX,
cooling operation is possible even during lower outdoor temperatures.
Note: This information is available for heat pump type.

A quiet outdoor unit is essential for your comfort and peace in your neighbourhood. SUPER MULTI NX
achieves a quiet sound level of 43 dB during Outdoor Unit Quiet Operation or Night Quiet Mode of the
3MXS52 during cooling operation. The minimum outdoor unit sound level is 39 dB.*
* Achievable when:
1. A single 2.0 or 2.5 kW class indoor unit is operating.
2. Indoor Unit Quiet Operation is selected for all indoor units in operation.
3. Outdoor Unit Quiet Operation is selected.
Note: Capacity may decrease when quiet functions are selected.
A quiet indoor unit is important for your personal comfort. SUPER
MULTI NX offers the quiet sound level of 22 dB during Indoor Unit
Quiet Operation of the FTXS20/25 during cooling operation.
Note: Capacity may decrease when quiet functions are selected.
