– 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.
