These two features work to significantly
reduce sound. Guides are added to the bell
mouth intake to reduce turbulence in the
airflow generated by fan suction. The Aero
Spiral Fan features fan blades with the bent
blade edges, further reducing turbulence.
Smooth Air Inlet Bell Mouth and Aero Spiral Fan
A larger sub-cooled area reduces refrigerant flow sound by making it easer to form
a liquid seal in front of the electrical valve.
SC heat exchanger
Super Aero Grille
Refined ventilation mechanism enables further reduction in required fan power.
Escaping eddies are sucked
in by the bent blade edges,
reducing overall turbulence.
A collection of cutting-edge technologies
realises efficient and quiet operation.

DC fan motor
Efficiency improved in all areas compared
to conventional AC motors, especially at
low speeds.

Sine wave DC inverter
>> Smooth sine wave DC inverter
Use of an optimised sine wave
smoothes motor rotation, further
improving operating efficiency.
Use of neodymium magnets in the motor
enables efficient generation of high torque,
reducing the size of the compressor.
>> Powerful magnets
Changes to the shape of the spiral and volume
ratio result in optimal refrigerant layout.
>> Optimal refrigerant configuration
The strength of the casing has been increased
by boosting the internal dome pressure.
>> Stronger materials
Overheating losses are reduced by pressurising the area
around the motor, boosting energy saving performance in
conjunction with other features.

DC motor
By introducing high pressure oil, the
reactive force from the fixed scroll is added
to the internal force, thereby reducing
thrust losses. This results in improved
efficiency and suppressed sound levels.
