Item Description
Air filter ● Indoor return air filter: G4 filters
● Outdoor intake air filter: G3 filters
Precoolin ● Wet film spraying for evaporative cooling lowers water
g module quality requirements and improves environmental
adaptability. The structure is simple and easy to
disassemble, clean, and maintain.
● Spray water is in direct contact with the precooling
module. The precooling module is periodically maintained
to prevent the core from scaling and corrosion.
Heat ● An efficient heat exchanger core is used. The heat
exchange exchanger core adopts the innovative flow design, which
r core improves efficiency and reduces air resistance.
● The heat exchanger core has high adaptability. It applies
to high-temperature, low-temperature, and high- and low-
temperature impact environments.
Condens The condenser adopts the flow design with a low wind
er resistance.
Exhaust ● A Huawei-developed high-speed fan is used, which
fan features large air volume, high static pressure, high
reliability, and a long service life.
● The fan is separated from the drive. The fan efficiency is
improved by more than 8% compared with a common EC
fan.
● The direct drive that the fan adopts has higher
transmission efficiency than the belt drive, which reduces
belt replacement and routine checks.
Evaporat The synergy field principle and computational fluid dynamics
or (CFD) are used to optimize the flow path design, greatly
improving the heat exchange efficiency. The evaporator air
flow organization is more reasonable, and the air resistance
is smaller.
Spray ● A horizontal three-stage centrifugal pump is used, which
pump features high pump lift, small size, high reliability, and
long service life.
● The water pump is made of new lubrication sealing
material. Wear parts such as water pump spindle seal and
seal ring do not need to be maintained in the life cycle.
● The variable-frequency drive power supply mode is used
to implement soft startup of the water pump, improving
the pump reliability.
