Due to optimization of outlet design of air flow with our
new advanced technology, sufficient air flow is secured
and long reach of air flow is realized.(FDT)
For person who is far
from the indoor unit
For both persons who are
feeling hot or cold
Can cool both the kitchen
and the guests
Expansion of outlet air flow area realizes
reduction of pressure loss caused by air flow
in the indoor unit. Load of fan motor is
decreased and efficiency is increased.

• Increase of heat transfer efficiency
Applying high efficient piping in heat exchanger and
optimization of heat exchanger (2parts 1part)
increases heat transfer efficiency.
Furthermore applying DC
fan motors, the highest
energy efficiency level,
reduction of weight and
significant compact design
are realized.
Individual flap control system
According to room temperature conditions, four
directions of air flow can be controlled by individual flap
as preferred.
As individual flap control is available even after
installation, installation area became wider than before.
The thinnest design
Thanks to new design of heat exchanger changed from 2 parts to 1 part, the
height of indoor unit is reduced drastically.
based on 50% capacity of FDT100V in heating operation
Air-conditioners are generally selected with the operation under the most severe ambient temperature conditions.
The inverter constantly adjusts compressor output to meet the exact demand of the indoor units.
i.e. In case that selecting the capacity of an inverter air-conditioner based on heating operation at -5°C, its capacity drops by
50% at 7°C(ISO-TI measurement condition) and operation period at 50% capacity is normally longer than that at 100% of
nominal heating capacity.
Considering annual electrical power consumption of inverter air-conditioners, it is quite important to give the first priority to 50%
actual capacity and selecting inverter air-conditioners is the best solution for saving energy and protecting the environment.
Consideration on the Environment
All models of the New inverter series use a new
refrigerant R410A characterized by the ozone
depletion coefficient being 0.
In order to comply with RoHS standard, the new inverter
series products use lead-free solder. It was considered to be
too difficult to use lead-free solder because it requires higher
soldering temperatures at assembling, which could jeopardize
the reliability of assembly, etc. PbF soldering method
developed by us, however, has enabled a higher reliability for
lead-free printed circuit boards.
*"RoHS" is the abbreviation of the new European standard, which means
Restriction of Hazardous Substances.
Employment of lead-free solder Employment of the new refrigerant
A High Performance and Excellent Energy Conservation
are achieved at the same time by an increased capacity of
heat exchanger and employment of high efficiency DC
motor etc.
