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.
