2.2. Low-noise outdoor units
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.
