2.2.New low-noise outdoor units
[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.
CS-F34DD2E5 CU-L34DBE5 / CS-F43DD2E5 CU-L43DBE5 /
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.
