[Product features]
2.2.1. Low-noise design improves in
surrounding areas
1. The noise-suppressing winglet fan is a result of new
research into vane design theory. The unique curved shape
suppresses the generation of vortexes, thus reduces air
flow noise.
2. The adoption of double-orifice rings reduces air passage
resistance.
3. Strengthening of the noise insulation materials in the
compressor and the sealing-in of mechanical noise allows
vibration noise to be greatly enclosed and suppressed.
4. The heat exchanger has an L-shaped design to allow air to
flow more smoothly.
5. Noise is automatically reduced further during night time
operation with lower outdoor air temperatures.
2.2.2. Automatic restart function
When the electric power resumes after a power failure, the unit
will automatically restarts the operation in the pre-failure mode.
2.2.3. Low ambient cooling operation
Cooling operation is possible at outdoor temperature of -5°C.
2.2. New low-noise outdoor units
