– 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-
shaped evaporator optimizes the airflow organization 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 tubes are adopted to enhance the heat exchange
performance, increasing the heat exchange efficiency by more than 10%
when compared with a traditional solution.
– The designed pressure bearing capacity of the heat exchange coil is 4.35
MPa, providing excellent pressure resistance capability.
EEV
– The throttling device uses a miniature controller to control the operation
of the step motor, thereby changing the pass-through area of the EEV to
regulate the flow of refrigerant.
– The main control module contains an EEV energy storage unit to prevent
slugging due to refrigerant migration after an unexpected power-off.
Oil separator
The oil separator separates the lubricant brought out due to discharge of the
compressor and brings back the separated lubricant to the compressor.
Sight glass
The sight glass allows users to observe the refrigerant flow and the content of
gas and liquid for easy maintenance and optimization.
Filter dryer
The filter dryer absorbs water from the refrigerant pipes and filters out the
foreign matter, which reduces component damage rates and improves
operating efficiency and reliability.
Air filter
The G4 air filter is used.
Electric heater
– The positive temperature coefficient (PTC) electric heater automatically
adjusts heating capacity and provides multiple protection measures to
ensure safe and reliable operation.
– 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.
– Uses a simple structure and is easy to remove, clean, and maintain.
– Quickly starts and generates huge humidification capacity.
– Consumes low power, saving more than 95% energy compared with a
traditional electrode humidifier.
– Provides a longer service life and maintenance interval than a traditional
electrode humidifier.
