Energy Saving
By controlling current frequency according to the desired temperature setting and outside air conditions, energy-efficient
performance is assured. Frequency is lowered when less power is required to substantially reduce electricity consumption
for a more economical operation. Providing you with more economy and comfort throughout the year, inverter control
presents an ideal situation as it reduces compressor rotation speed when the air conditioning load is low so it’s like using a
small compressor with a large heat-exchange unit.

The newly developed concentrated winding DC motor (linked core type) is friendly to the environment as
it uses less copper wiring than a conventional motor winding. This motor features a new high-density,
concentrated winding method that raises motor efficiency to 96%.
“Econo Cool” Mode
Ensures more comfort even when the set temperature is 2°C higher
than the conventional cooling mode.
The compressor motor adopts sensor-less flux vector control that uses a 32-bit RISC (reduced
instruction set computer) microprocessor. By converting the motor’s electrical current waveform from
the conventional waveform (120 conductance) to a sine wave (180 conductance), this microprocessor
raises the motor winding utilization ratio and reduces energy loss for higher efficiency.
This intelligent temperature control feature - that adjusts airflow interval to the body depending
on air outlet temperature - allows set temperatures to be raised by 2 degrees without any loss in
comfort for a 20% gain in energy efficiency.
Compared to the conventional active filter method, simple partial switching method PAM
control found on the new models in the line-up reduces energy loss. When combined with
vector control inverter, PAM control also allows for greater power and efficiency.

PAM adjusts the form of the current wave so that it is close to that
of the supply voltage wave. High harmonics are reduced and 98%
