④
Using 180-degree sine wave drive program, improve the system vibration and
noise performance and energy efficiency while broadenning the scope of the
system ability.
⑤
Using a new generation of higher reliability PFC program, further improve the
system reliability, and effectively improve the system’s harmonic performance and
energy efficiency at the same time.
⑥
Outdoor switching power supply use new circuit, to reduce electromagnetic
interference.Quad output switching power supply to the system control, AC and DC
fan driver, PFC control circuit and module-driven electricity. In which system control
and other three-way power supply is fully isolated and improve reliability.
⑦
Touch keys design, to highlight user-friendly design.
⑧
The dedicated disply communications circuits, improved anti-jamming capability.
⑨
Display and indoor power supply circuit are separated, and improved the
reliability of the work.
⑩
Panel detection use photoelectric switch, and improved the reliability of
detection.
3.2.2 System characteristics:
Using high-efficiency DC compressor match with the large area of condenser and
evaporator, So air-conditioner could run stable and reliable, and energy-efficient.
3.2.3 Structural features:
Indoor structural elements is a new design
Panels: The upper panel is with a motion mechanism, which uses rack and
pinion driving program. The upper panel slides up when heating up,
and the center and both sides of the baffle open. However, the
upper panel is still, and the top and both sides of the baffle open.
The inlet use the sides and bottom inlet. The sides baffle use inside
and outside two-baffle program. The outer baffle meet the
requirements of design, while the inter baffle meet the requirements
of outlet.
Cabinet section: As the first use the material of color-coated side, eliminating
the need for spraying process. The first time using the overall style
of the case structure, using a combination production technology of
press and online bending, And using TOX riveting technology
without rivets to rivete fan backplanes, improving their appearance
and stability of the overall structure; Adopting a new duct design,
plastic volute as well as the 380mm diameter fan to further reduce
noise.
Outdoor cabinet universal W3C.
3.2.4 Additional features:
----High-efficiency compressor, High cooling capacity, Reliable and Durable.
