Note:
■ Working conditions for cooling: inlet air temperature - dry/wet
bulb 27°C/19.5°C; temperature of inlet/outlet water - 7°C/12 °C.
■ Working conditions for heating: inlet air temperature - dry bulb
21°C; inlet water temperature 60°C; water flow - equal to that for
cooling
operation.
■ Rated air flow is measured under standard atmosphere using dry
coils (dry bulb 20°C).
■ Sound pressure grade and sound level are measured in a
semi-silent room as per GB/T 19232-2003.
■ H, M and L represent high, medium and low fan speed respectively.
■ Static pressure refers to outlet static pressure.
■ All performance parameters in the above table are measure with a
power supply of 220V~/50Hz.
■ The right/left orientation of connection pipes are exchangeable
on site (cooling/heating capacity needs to be multiplied by a
correction factor
of 0.93 after exchange).
1.Compact Exterior
With a compact, graceful and robust design, this
super-thin unit can be concealed in a small space
inside the ceiling.
2.Low Noise
The unit features a forward-pitched low-speed centrifugal fan with
wide impellers. The fan has a good
dynamic balance and a stable performance, and minimizes the
operation sound while ensuring enough air
flow and the static pressure of outlet air by using efficient
sound-dampening and heat-insulation material.
3.Efficient and Energy Saving
To maximize heat transfer and exchange efficiency, the unit
features heat exchange coils made of quality
copper tubes, efficient hyperbolic aluminum shutter fins, precise
mechanic tube expansion and a fan with
wide impellers and a high air supply capacity.
4.Easy and Flexible Installation
The unit features a symmetric design and can be easily installed.
The left and right connection pipes are
exchangeable. For units with a return air plenum, the air return
mode can be customized.
5.Safe and Leakage-proof
The condensate water collector are molded as a whole (no welding
line or dots) and entirely coated with
fireproof material to prevent leakage. A specially designed pitch
on the collector also helps ensure smooth
discharge of condensate water.
6.Easy Maintenance
The unit features a single-phase capacitive motor with a low
operation sound and a long service life thanks
to a quality precision ball bear that is hermetic, fully
lubricated, rustproof and durable. All wires leading out of
the motor are protected against damage using flexible metal tubes.
