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.
■ All performance parameters in the above table are measure with a
power supply of 220V~/50Hz.
1.Stylish Exterior
The unit is stylish and ultra-thin, fits various decoration styles,
and meets decoration as well
as cost saving requirements.
2.Silent Operation
The unit features an optimal design and a high-efficiency low-sound
centrifugal fan, and has undergone strict
motion/rest rectification to ensure that it works at high
efficiency with low noise.
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 centrifugal
fan with wide impellers, high air supply capacity, and low noise.
4.Filter
A washable nylon air filter with primary efficiency is installed at
the air inlet to ensure air quality.
5.Multi-grade Modulation
The unit features a single-phase capacitive motor with a high
precision ball bearing to provide three grades
which can meet various air rate requirements.
6.Easy to Install and Maintain
The unit is ceiling mounted and requires no special processing for
walls and ceilings. The filter at the air inlet
can be easily removed and replaced.
