High Eciency Inverter Compressor
Large-power Startup and Low-power Operation
The DC inverter compressor will run cooling at the largest power input and largest airflow each time it is started until
the set temperature is approached. Then, it runs at a low speed and low power input, which will not only keep the
temperature from fluctuating, but will also avoid frequent starting and stopping of the compressor, in result, prolonging
its service life.
Taking a room of 160ft2 as an example, the air conditioning time of the DC inverter unit is 6-10 minutes shorter then that
of the non-inverter one. After the set temperature is reached, the DC inverter compressor will run using 90% less energy
then the non-inverter compressor, therefore resulting in temperature loss being controlled and keeping temperatures at
steady settings. Which cuts down on the electrical consumption and greatly improves the energy eciency.

High Eciency PMSM
As for the DC inverter compressor with the permanent magnetic synchronous motor (PMSM), there is no current
through the motor rotor, no eddy current loss, and little heat produced, which means less ineective power loss so
that the motor’s efficiency is improved and the power input is reduced greatly.

High Eciency Fan Motor
High-efficiency motors are used and will save power significantly.
Stepless Regulation
According to customer’s needs, system output and operating frequency can realize stepless regulation within
10%~120% and 22Hz~80Hz respectively. Thus, energy efficiency is improved.
180° Vector Control technology
With DC Inverter 180° Vector Control technology, the compressor can run more smoothly. According to spectral
analysis, the harmonic wave of the DC inverter compressor is smaller than that of a common inverter compressor.
With lesser heat output and higher energy efficiency, the motor can save up to 20% energy consumption per year.
High Eciency Heat Exchanger
High Eciency Fan Motor
Micro Channel Heat Exchanger*
Micro Channel Heat Exchanger (MCHX) transfers heat trough
multiple flat fluid-filled tubes containing small channels, which
can enhance the heat transfer coefficient so that the heat
exchange efficiency is increased by 30% compared to the
normal fined tube heater exchanger.
Note * for cooling only condensing unit.
Evaporator
Inner Groove Copper Pipe
Special thickened inner groove copper tube
enhances heat exchanging performance.
Hydrophilic Blue Fin
Highly anti-corrosion blue hydrophilic coated aluminum fin has
longer lifespan than common fin. Heat exchange circuit is optimized
in design to best utilize the heat exchanging capacity of evaporator.

Quiet Design
Low Running Noise with Quality
Insulation
The inverter compressor is insulated with a high quality
noise absorption sponge, which is capable of reducing
the running noise remarkably, e.g. by 3-4dB at the
highest frequency.
Comfortable Airflow
Lower Running Noise at Lower
Running Frequency
The inverter compressor and fuzzy control technology,
adopted by inverter air conditioner, are able to
control the cooling speed according to the indoor
temperature change. It features the low noise and it
is proved by the test that the noise of the inverter air
conditioner is lower and service life is 5-8 years longer,
compared with the non-inverter air conditioner.
Low Noise Fan Motor
System adopts low noise motor and optimized
3-dimensional stream blades so that there is lower
noise while efficiency is ensured.
High ESP Design
The high static pressure design of indoor unit can
ensure enough air volume for every room that is
connected to the system. Comfort level of every room
is guaranteed.
High ESP Design
The duct connects with multiple diusers to ensure
even distribution of airflow and optimizes the air
quality.
High Reliability

Strong Anti-corrosion
Moisture Resistance and Damp-proof
This system can still operate reliably even under damp
or wet conditions, thanks to both the damp-proof
design of the electric box and the damp-proof oil that
coats the control board.
Humidity-status tests (working condition: 30/29)
and rainfall tests (full-range and severe rainfall on the
entire unit) have been taken to the system. Moisture
resistance grade is IP24.
187 V
Safe Operation Range
254 V
Anti-corrosive
The outer case of outdoor unit is made of painted
steel and galvanized to prevent corrosion and rust
eectively.
It passed a 1000-hour test in salt mist and proved to
be corrosion-proof.
Wide Operation Voltage Range
The unit can safely operate within 187~254V.
High/low pressure protection
When suction pressure is too low or discharge
pressure is too high, compressor will stop, and unit
displays a malfunction code.
Over current protection
Once the current of the compressor is higher than the
normal level, compressor will stop and the unit will
display a malfunction code.
Reverse (open) phase protection
Once the phase sequence of power supply is
incongruent or the phase is absent, unit will shut o to
protect itself from damage.
Comprehensive Protection
Overload protection
Compressor has its own overheat protection. Once the
temperature of compressor is higher than allowable
level, compressor will stop and only when temperature
recovers, compressor will restart.
Discharge high temperature protection
Once the discharge temperature of the compressor is
higher than allowable value, compressor will stop and
the unit will display a malfunction code.
Temperature sensor alarm
Once temperature sensor is o or short-circuited,
system will indicate the error code and give an alarm.

Easy Installation
The indoor unit can be installed with either horizontal or vertical furnace so as to meet various installation requirements.
Flexible Electronic Expansion Valve
The electronic expansion valve guarantees that the
system makes adjustments automatically according
to the changes of the circumstances and water
temperature. It is more energy saving and stable than
capillary.
Compact Design & Easy Maintance
The newly designed 4-sided detachable case is
capable of not only accommodating the large-sized
electric box, but also keeping a compact structure. The
compact design of the indoor and outdoor unit helps
to reduce the installation space and transportation
cost. The fan system is dismountable to simplify the
maintenance.
Intelligent Control
For more details visit www.mrcool.com
Precise Temperature Control
Both wired thermostats and outdoor units are furnished with a temperature sensor, which can precisely detect the
outdoor and indoor temperature. The compressor can then adjust the power input based on the change of the
indoor and outdoor temperature, as to supply more even airflow, which provides the occupants a more comfortable
setting.
Indoor Unit Separate Control
Indoor units are separately controlled through the wired thermostat. Even though the unit is turned o, FAN mode
can still be the realized through the Fan button on the wired controller.
Memory Function (optional)
Two statuses of “Memory On” and “Memory O” can be configured for the thermostat. This function can save the
repeated setting owing to any power failure.
When the controller is set to “Memory On”, the controller can memorize the running status before the power failure
and resume the previous running status after the power restoration.
When the controller is set to “Memory O”, the running air conditioner will go to the standby status in the event of
power failure.
Other Functions
ON/OFF timer function | Switch between °C and °F | Filter-wash awake | Thermostat button lock
