The bat wing fan realizes the sound level equivalent to current model.
New
Vector-controlled inverter
Vector IPDU control changes motor current wave to a smooth sinusoidal pattern so that noise emitted from the drive units is greatly reduced.
Efficient circuit built-in and new PIM adoption
Smooth sign curve liquid realizes efficient-izing and low noise-ization.

Anti-eddy projection
Anti-eddy projection prevents big eddies and reduces air resistance.
Reverse-arc-shape wing
Reverse-arc-shape wing reduces air resistance.
DC twin rotary compressor (A3 comp) features
High reliability
The enhanced DC twin-rotary compressor delivers stable performance with minimum friction: Ideal for noise-sensitive applications. The outdoor unit is almost imperceptible.
TWIN-ROTARY COMPRESSOR
• Low vibrations
• Super-quiet operation
• High reliability
Comparison of DC twin rotary and Scroll compressor
This difference is the reason for actual energy savings
(%)
More effective compression from high-precision components
Partial load range
*Most frequent operation
Nominal range
Higher refrigerant compression from redesigned compression channels

Capacity correction in case of frost on the outdoor heat exchanger in heating
Correct the heating capacity when frost was found on the outdoor heat exchanger.
Heating capacity = Capacity after correction of outdoor unit × Correction value of capacity resulted from frost
