Low-noise design improves comfort in surrounding
areas
1. The noise-suppressing winglet fan is a result of new
research into vane design theory. The unique curved
shape suppresses the generation of vortexes, thus
reducing air flow noise.
2. The adoption of double-orifice rings reduces air
passage resistance.
3. Strengthening of the noise insulation materials in the
compressor and the sealing-in of mechanical noise
allows vibration noise to be greatly enclosed and
suppressed.
4. The heat exchanger has an L-shaped design to allow air
to flow more smoothly.
5. Noise is automatically reduced further during night-time
operation with lower outdoor air temperatures.

Pipes that are one size larger can also be connected for
renewal.

If renewing the system, existing refrigerant pipes can be
utilized so that only the indoor and outdoor units need to
be replaced.

For example, liquid and gas pipes from 10 years ago
can be connected to current pipes with the same size or
one size larger. Effective utilization of materials reduces
working time and trouble. (Adaptor sockets are not
supplied.)
