Unit installation

Sine-wave drive soft PWM
The inverter has been made more
compact by inserting the circuitry
inside a synthetic resin molding.
To ensure quiet operation, soft PWM
control is used to prevent the metallic
whine associated with conventional
inverters.

Advanced Technology for High Efficiency
Numerous Leading-edge Technologies
Assure High Efficiency
Reluctance DC Rotary Compressor
(PUHZ-RP71)
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.
Wider Performance Range
Operation is now possible at lower speeds, thus cutting energy losses
produced by the repeated On/Off operation of non-inverter models.
Comfort is improved while power consumption is reduced.
Highly Efficient Scroll Compressor
(PUHZ-RP100/125/140/170/200)
Higher efficiency has been achieved by adding a frame compliance
mechanism to the DC scroll compressor. The mechanism allows
movement in the axial direction of the frame supporting the cradle scroll,
thereby greatly reducing the leakage and friction loss, and ensuring
extremely high efficiency at all speeds.
DC Fan Motor
(PUHZ-RP71/100/125/140/170/200)
A highly efficient DC motor has been installed to drive the fan of
outdoor units, realising up to 60% higher efficiency when
compared to an equivalent AC motor.
Vector-Wave Eco Inverter
This inverter monitors the varying compressor motor frequency and
creates the most efficient waveform for the motor speed. As a result,
operating efficiency in all speed ranges is improved, less power is
used and annual electricity costs are reduced.
Power Receiver and Twin LEV Control
(PUHZ-RP71/100/125/140/170/200)
Mitsubishi Electric has developed a power receiver and twin linear
expansion valves (LEVs) that optimise the performance of the compres-
sor. By ensuring optimum control in response to the operating
waveform and outdoor temperature, this technology is tailored to the
characteristics of the new refrigerant to enhance operating efficiency.

Advanced Energy-saving Technologies
Highly efficient fan and grille for outdoor unit
The shapes of the fan and grille of the outdoor unit were redesigned,
realising an increase in blowing capacity and more efficient heat
exchange while maintaining the same operating noise level.
Highly efficient heat exchanger
A high density and increase in surface area have improved the
heat-exchange efficiency of the heat exchanger.

Outdoor unit fan opening increased
<
PUHZ–RP170/200
>
The diameter of the opening for the fan in the outdoor unit has been
increased from 490 to 550mm. Blowing capacity has been increased
while maintaining the same fan rotation speed.
High-density heat exchanger
<
PUHZ–RP170/200
>
The pipe diameter has been changed from
9.52 to 7.94mm, resulting in a high-density
heat exchanger.
Grille shape changed
<
PUHZ–RP170/200

The shape of the air outlet grille has been changed to reduce pressure
loss. This has helped improve heat exchange performance.
Inflexed fan

Adoption of a fan with improved
ventilation characteristics and a
newly designed rear edge that
suppresses wind turbulence raises
fan operation efficiency.
