4. Product Features



Sine Wave DC Inverter

Reluctance DC CompressorHigh energy-efficiency in the most frequently used mid-to-low setting keeps annual electricity costs low.

DC Fan MotorAlong with the efficient operation in the whole range of low speed to high speed, the more improvement is done especially in the low speed operation, compared with the conventional AC motor.

Super Aero Grille Improves COP by reducing power consumption for fan

operation while maintaining the large airflow rate.

Aero Spiral FanBending of the fan blade edge reduces turbulence, resulting in less pressure loss.

Smooth Air Inlet Bell MouthA guide is built at the bell-mouthed suction

inlet for reduction of turbulence that occurs

at the fan inlet and, as a result, the quiet

operation is achieved. I-demand functionMaximum power consumption can be easily controlled. The option minimizes the difference between actual power and predefined power consumption.

Neodymium magnets

With adoption of SINE wave, PWM, which smoothes the motor rotation, the operating performance is enhanced. And noise will be reduced.

Swing and scroll compressor are both driven by a motor using 4 neodymium magnets.

4. Product FeaturesEnergy Saving Technology



• Less frequent start/stop cycles

• Automatic throttle back of capacity

• Start-up time down by 1/3

New development

Leak eddy

Suction turbulence at conventional type

Smooth Air Inlet Bell Mouth


Low operating sound:

A guide is built at the bell-mouthed suction inlet for reduction of turbulence that occurs at the fan inlet and, as a result, the quiet operation is achieved.

The tip of the blade is bent for restraining the eddy that occurs at the tip of the blade and, as a result, a considerable noise reduction is achieved.

Leak eddy is sucked to the vicinity of blade tip and the turbulence is

reduced.



Night quiet function:

• Max. –5 dB(A) for a certain period

• Limiting max. compressor frequency & fan speed

• Starting time & ending time can be set


• 2 modes for end-user:

A) Automatic mode:

Time of max. T is memorized

B) Customized mode:

Starting and ending times can be set by external timer control
