− Fans can be maintained with power-on. You can replace one faulty fan without
shutting down the smart cooling product.
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 smart cooling product 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. 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.
− The wet film humidifier consumes less power, saving more than 95% of energy
compared with a traditional electrode humidifier.
