The inverter circuit provides optimum power control and
extremely efficient operation by changing the frequency of the power supply.
So even though you get speedy, flexible operation,
you use less electricity than conventional units.
WHAT'S AN INVERTER?
An inverter is a type of power conversion circuit that electronically
regulates the voltage, current, and frequency of a device. In an
inverter air conditioner, this circuit controls the revolutions of the
compressor — and hence the air conditioner’s output. Raising the
frequency increases the output, lowering the frequency reduces it. In
this way, inverter air conditioners provide much finer temperature
Advanced Inverter Performance —The Difference in Power and Comfort
Original Panasonic inverter circuit technology provides detailed
motor current control. A comfortable room temperature is
maintained with less energy, vibration, and noise.
The current waveform deviates
from the motor voltage
waveform,
so power is
wasted.
More Advantages with Panasonic
Our conventional inverter
Saves energy:
Newly developed bearing reduces
oscillation and mechanical loss.
Compact size, light weight:
New DC motor with rare-earth magnet
and no accumulator.
Less noise and vibration:
Smooth, continuously operating
vortex blades.

Electric Consumption
The current waveform closely matches
the motor voltage waveform, so power
consumption
is reduced.

Power is wasted when the car
swings off
course.
When the car stays right on course,
there’s no
power loss.
Compare this to a car rounding a corner
There's less
waste.
For optimum use of limited energy
resources, an inverter air conditioner
features an inverter circuit providing
extremely efficient operation. Improved
heat exchanger and compressor
performance, precise microcomputer
control and other innovations further
assure dramatically boosted efficiency.
So even though you get speedy, flexible
operation, you use less electricity.

The accelerator can't be adjusted, so you spend a long
time to get comfortable, then soon become uncomfortable.
Keeps the

comfortable
all the time.
Adjusts the accelerator
and thus runs
more economically.
Reaches the comfort
zone quickly.
START Runs at a fixed speed,
so it takes longer to reach
the comfort zone.

Quick comfort
As soon as the an inverter air
conditioner is switched on, it
provides the exact amount of power
needed to rapidly cool or heat of
the room. This enables it to reach
the set temperature in about a
quarter the time required by
non-inverter models. So you're
comfortable soon after you arrive
home on a hot summer day, or on a
cold winter morning.

The indoor unit delivers
whisper-quiet operation and the
noise of the outdoor unit has also
been reduced. Better still, using the
Quiet Mode lowers noise even further
to just 21dB for the indoor unit and
41dB for the outdoor unit. So now you
can enjoy a comfortable night’s sleep
without bothering the neighbours.
