>>Asymmetric Vortices
Motor Rotor With Neodymium Magnetic Material
Neodymium, an artificial permanent magnet, is one of the strongest magnetic materials to date. The magnetic force
of neodymium magnet is 10 times that of common ferrite magnet. Under the same volume, the electromagnetic field
intensity is stronger, the starting torque is larger, and the operation efficiency is higher.
>>
In view of the high pressure characteristics of R410A refrigerant, the compressor strengthens the bearing structure
and adopts the design of asymmetric scroll disk, which has the following advantages over the symmetrical scroll disk:
Reduce refrigerant leakage and
improve efficiency;
Two adjacent chambers have
small pressure difference, small
vibration and more mute;
Prevent over compression,
prolong the service life of the
compressor.

26 Double 'C' Type Heat Exchanger*
The Double C-type compact heat exchanger features a super-large surface area. This design not only increases
heat exchange efficiency but also reduces system pressure loss, resulting in superior performance under heavy-load
conditions.
Note: The heat exchanger structure and fan diameter are
determined by the specific model.
*Note: Only for 28HP and above
This new structural design optimizes system performance
under partial loads while minimizing the unit's overall footprint
30HP occupies only 1.6055m2
,
which is 21.4% less than the previous generation
Heat exchanger adopts the perfect combination of multi-coated hydrophilic aluminum foil heat exchange fins
and high-efficiency internally threaded heat exchange copper tubes, which greatly improves the heat exchange
efficiency and enhances the corrosion resistance and oxidation resistance of the heat exchanger.
The use of multiple rows of small-diameter tubes with reduced
spacing increases the tube count per unit length, thereby
significantly expanding the heat exchange area and boosting
efficiency.

4.6 Triple back-up operation technology
In units with two compressors, if one compressor fails, the other compressor can run on its own, to ensure the air
conditioning system can work stably.
In a multi-unit system, if one outdoor unit fails, the other modules provide backup so that the system can continue operating.

If the system is connected to multiple modules, in order to ensure the balance of compressor operation, the
automatic control of the microprocessor on the host can realize the automatic rotation operation function
between the modules, effectively extend the service life of the unit.

their service life. (Applicable to dual-compressor units).
Compressor Rotation

The external force blows
the outdoor unit fan to
rotate in reverse. At this
time, start and stop the
rotation of the fan, and
then restart the fan motor
in a forward rotation
according to the normal
procedure, so as not to
damage the fan blades
due to excessive starting
current.
An external force causes the fan to
rotate in the opposite direction
An external force causes the fan to
rotate in the opposite direction
Start the unit and stop running Positive rotation, low starting
torque, protect the fan blade
Instant reverse rotation, torque suddenly increased,
easy to cause fan blade damage
When the power cord of the outdoor unit is connected incorrectly,
the circuit will start self-protection to avoid impact and damage to
the main control board, inverter module and compressor. Ensure the
normal operation of the air conditioner, without accidental electrical
damage, fire, etc.
Automatically recognize the working voltage, when the voltage is too low, give an early warning in time, and control
the power consumption and capacity output of the multi-line system through the corresponding limit frequency.
The outdoor unit has a builtin anti-seismic module, which
has anti-seismic and antiinterference functions to ensure
the safe and stable operation of
the system in bad weather.
When the compressor casing or
motor temperature is too high,
the circuit will automatically cut
off to prevent the compressor
from overloading and cause
electrical damage, fire, etc.
When the current exceeds the
set value, the temperature will
rise, and the motor will be cut
off in time during overcurrent
operation to protect the motor
from burning due to overload.

4.9 Anticorrosion design
It adopts anti-corrosion and anti-oxidation
hydrophilic aluminum foil heat exchange fins,
which have multiple protections of lubricating
coating, hydrophilic coating and corrosionresistant coating.
Improve the protection level of the motor. The
motor shaft is made of stainless steel. During the
installation process, the motor shaft, nuts, gaskets
and exposed motor shaft are coated with anti-rust
grease, and the motor body screws and top cover
screws are coated with silicone grease.
The main board is equipped with moisture-proof glue,
the sheet metal surface of the electric control box
is treated with anti-corrosion spray, and the top of
the metal casing fan capacitor is sprayed with anticorrosion paint separately.
The nails, nuts and washers are made of stainless
steel or high anti-corrosion materials, and the
screw heads inside the machine and outside the
electric control box are coated with silicone grease
for anti-corrosion.
The surface of the sheet metal parts is phosphated
and coated with special anti-corrosion materials.
It improves the salt spray resistance and heat and
humidity resistance, and greatly improves the anticorrosion ability of the sheet metal.
Use special anti-corrosion coils. The base layer
of ordinary galvanized sheet is increased with
electrophoretic layer to achieve anti-corrosion
effect. The coil fixing screws are stainless steel
screws.
