Specifications

The newly developed scroll com-
pressor is equipped with a “Frame
Compliance Mechanism” that al-
lows movement in the axial direc-
tion of the frame supporting the
cradle scroll. This greatly reduces
both leaking and friction loss, en-
suring very high efficiency through-
out the speed range.
The reluctance DC motor has a rotor equipped with
powerful neodymium magnets. The magnetic torque
produced by the neodymium magnets and reluctance
torque results in more efficient operation.
This produces the most efficient waveform in response
to varying compressor motor rpm. By improving operat-
ing efficiency from low to high speeds, annual electricity
costs are reduced.
Mitsubishi Electric has developed a power receiver and
twin LEVs
(
linear expansion valves
)
that optimise the
performance of the compressor. By ensuring optimum
control in response to the operating waveform and out-
door temperature, this technology is tailored to the char-
acteristics of the new refrigerant to enhance operating
efficiency.
A high-efficiency DC motor drives the fan of the
outdoor unit. It offers up to 60% greater efficiency than
an equivalent AC motor.

Numerous Leading-edge Technologies Assure High Efficiency
The inverter has been made com-
pact by insert-moulding the cir-
cuit pattern in synthetic resin.
To ensure quiet operation, soft
PWM control is used to prevent
the metallic whine associated with
conventional inverters.
