VRF SYSTEMS INDEX
Energy control and reliability
The Mini ECOi system delivering energy-saving performance, powerful
operation, reliability and comfort surpassing anything previously possible.
3 layers
Powerful heat exchanger.
Panasonic twin rotary compressor.
Design fan.
3 layers of heat exchanger for all LE Series. LE Series
features the same heat exchange volume as conventional
model even though it is 15% smaller in size.
A large capacity Inverter compressor has been adopted.
This compressor features wider and 0,1 Hz step Inverter
control.
Fan braves have been redesigned to inhibit air resistance
and to increase efficiency. The larger fan increases air
flow while maintaining low noise levels.
Energy savings design
1 | Panasonic Inverter compressor. A large-capacity Inverter
compressor has been adopted. The Inverter compressor is
superior in performance with improved partial-load capacity.
2 | Printed circuit board. Maintenance is made easier with only
2 PCBs.
3 | Accumulator. A large accumulator has been adopted to maintain
compressor reliability because of the increased refrigerant
quantity, which allows an extended maximum piping length.
4 | DC fan motor. Checking load and outside temperature, the DC
motor is controlled for optimum air flow.
5 | Blade shape. The fan blades have been developed to inhibit air
turbulence and increase efficiency. As the fan diameter has been
increased, air flow has also increased whilst maintaining a same
sound level.
6 | Heat exchanger and copper tubes. The heat exchanger size and
the copper tube sizes in the heat exchanger have been redesigned
to increase efficiency.
7 | Oil separator. A centrifugal separator has been adopted to improve
oil separation efficiency and reduce refrigerant pressure loss.

Heat
exchanger
(Bluefin
condenser)
Bluefin condenser: high durability outdoor unit
The anti-corrosion Bluefin treatment of the heat
exchanger provides greater resistance against corrosion.
All models are equipped with Bluefin condenser and
corrosion-resistance treated for high resistance to rust
and salty air to assure long-lasting performance.
Maximum comfort with quiet operation mode
· Quiet operation mode reduces outdoor unit operating
sound by 7 dB(A)
· 4-step set point is available
· Silent mode 1 maintains rated cooling capacity

Superior seasonal energy efficiency (SEER / SCOP
follows LOT21*)
The operation efficiency has been improved using highly
efficient R410A refrigerant, a DC Inverter compressor, DC
motor and a heat exchanger design.
* SEER / SCOP is calculated based on the seasonal space cooling / heating efficiency “η” values of
the COMMISSION REGULATION (EU) 2016/2281. SEER, SCOP = (η + Correction) × PEF.
