Inverter Series

Doing Our Part to

Create a Better Future for All
Core Environmental Policy
Mitsubishi Electric promotes sustainable development, and is committed to protecting
and restoring the global environment through technology, all of its business activities
and the actions of its employees.
Simply meeting industry standards, however stringent, is not enough.
Our aim is to exceed them. When it comes to comfort, efficiency and durability,
Mitsubishi Electric offers you a distinctive advantage. We call it MEQ
Mitsubishi Electric Quality. It results in benchmark leading-edge products like our
air conditioners, which consume minimal power, protect your investment through
a long service life, offer superior reliability and are built to take the punishment of

R 410A refrigerant
As scientific evidence points to man-made chemicals for the damage caused to the ozone layer, we only
use chlorine-free refrigerants that are safe and rated zero ODP (Ozone Depletion Potential). Accordingly, our
systems require less energy to run and have a significantly lower indirect global warming potential. In short,
we produce the most efficient equipment possible, while helping to protect the environment.

extreme weather conditions year in and year out.

The Montreal Protocol calls for the complete abolishment of HCFC (such as R22) refrigerant production by the year 2020.

Mitsubishi Electric is committed to shifting over to HFC models from HCFC models.

Mitsubishi Electric Offers

Montreal Protocol

Three Important Advantages

Mechanism of ozone layer depletion by HCFCs

Ultraviolet rays

Montreal Protocol regulates HCFCs

Comfort

Efficiency

Durability

HCFC production has been regulated since 2004.

HCFCs will be entirely banned by 2020.

MEQ has led to the development

of state-of-the-art air purification
and deodorization filters that
remove unwanted odors and
impurities in the air. Original airflow
technologies and specially
designed components provide
even temperature distribution
even in remote regions of a room.
At Mitsubishi Electric, comfort
doesn't simply mean cool or warm,
it means clean and quiet too.

Optimum cost performance and

energy savings...

Rugged construction, rigorous

testing, long-lasting operation...

MEQ results in air conditioners

that are rated among the best in
the industry in terms of quality
and energy efficiency. We strive
for a perfect balance of performance, reliability, low power
consumption and long service life.
This is complemented by continuously introducing new technologies
and components that further
reduce energy requirements and
negative environmental impact.

MEQ is behind a mindset that goes

to extremes to ensure higher quality
products that protect the initial
investment over years of reliable
service. We subject our indoor and
outdoor units to rigorous durability
testing, including harsher temperature extremes than likely found
anywhere in the world.

UV radiation causes CFC molecules to breakdown and release

chlorine atoms.

Ozone molecules react with chlorine atoms and are broken down
into oxygen atoms and chlorine monoxide.
Oxygen atoms react with chlorine monoxide to form oxygen
molecules and chlorine atoms.

Chlorine atoms react with ozone molecules again. This repetition

continues, depleting the ozone layer.
HFC refrigerants do not contain chlorine, the causative agent of
ozone layer depletion, which HCFC refrigerants contain.Therefore,
Mitsubishi Electric has shifted over to HFC (R410A) refrigerants from
HCFC (R22) refrigerants.

INVERTER TECHNOLOGIES

OTHER TECHNOLOGIES

Mitsubishi Electric inverters ensure superior performance, including the optimum control of operation frequency. As a result,
optimum power is applied in all heating/cooling ranges and maximum comfort is achieved while consuming minimal energy.
Fast, comfortable operation and amazingly low running cost Thats the Mitsubishi Electric promise.

MORE ADVANTAGES WITH MITSUBISHI ELECTRIC

Joint Lap DC Motor

INVERTERS HOW THEY WORK

Inverters electronically control the electrical voltage, current and frequency of electrical devices such as the compressor motor in an air
conditioner. They receive information from sensors monitoring operating conditions and adjust the rotation speed of the compressor, which
directly regulates air conditioner output. Optimum control of operation frequency results in eliminating the consumption of excessive electricity
and providing the most comfortable room environment.

PAM (Pulse Amplitude Modulation)

Mitsubishi Electric has developed a unique

motor, called the Poki-Poki Motor, which is
manufactured using a joint lapping technique. This innovative motor operates based
on a high-density, high-magnetic force, leading to extremely high efficiency and reliability.

PAM is a technology that controls the current waveform so that it resembles the supply voltage wave, thereby reducing loss and realising
more efficient use of electricity. Using PAM control, 98% of the input
power supply is used effectively.

ECONOMIC OPERATION
Impressively low operating cost is a key advantage of inverter-equipped air conditioners. We have combined advanced inverter technologies
with cutting- edge electronic and mechanical technologies to achieve a synergistic effect that enables improvements in heating/cooling
performance efficiency. As a result, better performance and lower energy consumption are achieved.

Powerful neodymium magnets are used in the rotor of the reluctance

DC motor. More efficient operation is realized by strong magnetic and
reluctance torques produced by the magnets.

temperature setting to its original value. The Auto-return function automatically
resets the temperature back to the original setting after a specified period of time,
thereby preventing overcooling. The Auto-return activation time can be set in 10minute units, in a range between 30 and 120 minutes.

Dot Liquid-crystal Display Adopted

Easier to read thanks to use of a full-dot liquid-crystal display with

backlight, and easier to use owing to the adoption of a menu format
that enabled the number of operating buttons to be reduced.

R410A and R22 are chemically stable, low-toxin, non-flammable

refrigerants. The relative specific gravity of R410A is greater than that
of air. In the unlikely event that this refrigerant leaks into a closed
room, it will accumulate low to the floor, causing a lack of oxygen
in that air layer and possible result in an accident. Additionally,
poisonous gas may be produced if R410A comes into contact with
open flame. So please be certain to handle it only in well ventilated
areas where the accumulation of leaking refrigerant can be prevented.

SUY-KA

R410A is a near-azeotropic refrigerant blend of R32 and R125, so

R410A can be handled in almost the same manner as a singlecomponent refrigerant like R22. However, the composition between
gas and liquid phases changed slightly when in a container like a
cylinder. Therefore, charge R410 in the liquid phase.

As the vapor pressure of R410A is 1.6 times that of R22 at a

given temperature, perform charging at the time of installation
using dedicated anti-high-pressure tools and materials for
R410A. (Reference: Table of thermophysical properties by JRAIA,
NISTREFPROPV5.10, Asahi Glass Co., Ltd. and others.)

Xg=30g/m x (length-30)m

Handling Precautions
Mixing of refrigerants

Control of moisture

R410A is a refrigerant blend of HFC32 and HFC125. R22 has different

properties from R410A. Therefore, never mix R410A and R22.

If excessive moisture gets into the refrigerant system, it can cause

capillary clogging, deteriorate compressor insulation, etc.

Pressure rise (R410A)

Control of contaminants

As the vapor pressure of R410A is 1.6 times higher than R22 at a given
temperature, use dedicated extension pipes for R410A. Tools dedicated
for R410A may also be required. Special care should be taken when
charging units with R410A.

If waste, air, flux, mineral oil, etc. get into the refrigerant system, it
accelerates the resolution or deterioration of the refrigerant oil, which
causes capillary clogging, deterioration of compressor insulation, etc.

Notice
Do not install indoor units in areas where the emission of VOCs such as phthalate compounds and formaldehyde is known to
be high (e.g., mobile phone base stations) as this may result in a chemical reaction.
When installing, relocating or servicing air conditioners, use only the specified refrigerant (R410A) to charge the refrigerant lines.
Do not mix R410A with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, this may cause abnormal high pressure in the refrigerant lines and possibly result in an explosion
or other hazard.
The use of any refrigerant other than that specified for the system will cause mechanical failure, system malfunction or unit
breakdown. In the worst case, it could lead to a serious impediment to securing product safety.
