2.2 High efficiency
2.2.1 High efficiency DC inverter compressor
High efficiency DC inverter twin rotary compressor
2.2.2 High efficiency DC motor
According to the running load and pressure, it controls the speed of DC fan to achieve the minimum power
consumption.
2.2.3 High efficiency heat exchanger
The new designed window fins enlarge the heat-exchanging area, decrease the air resistance, save more
power and enhance heat exchange performance.
Hydrophilic film fins and inner-threaded copper pipes optimize heat exchange efficiency.

2.3 Enhanced comfort
2.3.1 Intelligent soft start technology
2.3.2 Night silent operation mode
Midea's Night Silent Mode feature which is easily set on the PCB board allows the unit to be set to
vary time options during Non-Peak and Peak operation time optimizing the units noise output.
Night silent operation will be activated X hours after the peak temperature during daytime, and it
will go back to normal operation after Y hours.
Model 1
→ X: 6 hours, Y: 10 hours Model 2 → X: 8 hours, Y: 10 hours
Model 3
→ X: 6 hours, Y: 12 hours Model 4 → X: 8 hours, Y: 8 hours
Notes:
This function can be activated by setting at site. Temperature (load) curve shown in the graph is just an example.

DC inverter compressor soft start function reduces strike to the
electric network. This kind of high-performance and low sound scroll
compressor operates at a faster rate when starting, reducing start-up
time. It also helps the unit to quickly adjust the room temperature to
the set level.

General Information 5
2.4 Easy installation and service
2.4.1Compact design for effective use of space
2.4.2 Space saving design
The side discharge type is slimmer and more compact,
resulting in significant savings in installation space.
2.4.3 Simple signal line connection
Installation is easier as communication wiring can be shared by indoor & outdoor units. It’s easy for the user to
retrofit the existing system with a centralized control by simply connecting to the outdoor units.
2.4.4 Auto addressing
2.4.5 Easy maintenance
Forced cooling button makes outdoor unit run in cooling mode at
any condition, so it is very easy for you to charge refrigerant to the
system when it needs to be done. The self-diagnosis function
detects malfunctions in major locations in the system and displays
the type of malfunction and location. This allows service and maintenance
to be performed more efficiently.
PQE&XYE, just only one group of communication wire of PQE,
achieved both of communication for indoor & outdoor unit and
network.
Reversible communication, central controller can be connected
from indoor side or outdoor side as you wish.

Compact size and light weight design minimizes the installation
footprint, reduces the installation floor load, and easier for
transportation. For some projects the units can even be transported
through the elevator or forklift, lessen access problem at the jobsite.
