− There are ten EC fans in total. The air conditioner will not shut down when a single
fan fails.
− Fans can be maintained with power-on. You can replace one faulty fan without
shutting down the air conditioner.

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 V-type evaporator optimizes the airflow
pattern and reduces the air 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.
− The designed pressure bearing capacity of the heat exchange coil is 1.6 MPa, an
excellent pressure bearing capacity.

EEV
− The flow regulator uses a miniature controller to control the operation of the step
motor, thereby changing the pass-through area of the valve to regulate the flow of
refrigerant.
−
The EEV is equipped with an energy storage unit that prevents slugging due to
migration of refrigerant when the air conditioner is powered off abnormally.

Oil separator
It is an oil-gas separator which separates the lubricant brought out due to exhaustion of
the compressor and brings back the separated lubricant to the compressor.

Sight glass
It allows you to observe the refrigerant flow and gas content for easy maintenance and
optimization.

Filter dryer
It absorbs water from the refrigerant pipes and filters the foreign matter, which reduces
component damage rates and improves operating efficiency and reliability.

Air filter
The G4 air filter is used, and the F5 air filter is customizable. The air filter meets the
relevant requirements of the China National Standard GB/T 14295-2008.

Electric heater
− The positive temperature coefficient (PTC) electric heater automatically adjusts
heating capacity and provides multiple protection measures to ensure secure and
reliable operating.
− The heater features quick start, large heating capacity, and even heating.

Wet film humidifier
− The wet film humidifier has low water quality requirements and high environment
adaptability.
− The wet film humidifier has a simple structure and is easy to remove, clean, and
maintain.
− The wet film humidifier can quickly start and generate huge humidification
capacity.
