–
The drive is hot-swappable, and the fan can be maintained without
power-off.
–
The direct drive that the fan adopts has higher transmission efficiency
than the belt drive, which reduces belt replacement and routine checks.
–
Compared with fan speed control by the belt drive, fan speed control by
the direct drive has a wider application range which is not subject to the
transmission ratio.
–
The fan is controlled over RS485 communications. You can view the fan
power and speed in real time on the display module and obtain fault
information including fan blockage, overvoltage, and undervoltage. These
features allow you to view the status and locate a fault.
High-efficiency heat exchanger core
–
A Huawei-developed efficient heat exchanger core is used. The heat
exchanger core adopts the patented flow design, which improves
efficiency and reduces wind resistance.
–
The heat exchanger core is made of polymer materials and is corrosion
resistant. It is resistant to acidic, alkaline, and other corrosive gases.
–
The heat exchanger core features high adaptability. It applies to high-
temperature, low-temperature, and high- and low-temperature shock
environments.
–
The heat exchanger core has low water quality requirements. Common
softened water can be used.
Evaporator
–
The evaporator adopts the inner threaded copper pipe and blue
hydrophilic aluminum foil to prevent water blowing due to condensate
water accumulation and improve heat exchange performance. The
evaporator is designed in a straight line, which optimizes the airflow
organization and reduces the wind resistance.
–
The finned-tube evaporator with a high cooling efficiency adopts the
synergy field principle and computational fluid dynamics (CFD) to
optimize the flow path design, which greatly improves the heat exchange
efficiency.
–
The small diameter evaporator is adopted to enhance the heat exchange
performance, a 10%+ increase in heat exchange efficiency compared with
a traditional solution.
Condenser
–
The condenser adopts the inner threaded copper pipes and gold
anticorrosive aluminum foil. The condenser is designed in a straight line,
which optimizes the airflow organization and reduces the wind resistance.
–
The condenser spray technology is used to reduce the compressor power
and improve the energy efficiency in hybrid mode.
EEV
–
The throttling device uses a miniature display module to control the
operation of the step motor, thereby changing the pass-through area of
the EEV to regulate the flow of refrigerant.
–
The EEV is equipped with an energy storage unit that prevents slugging
due to migration of refrigerant after an unexpected power-off.
