2.2. Newlow-noise outdoor units

[Productfeatures]

2.2.1. Low-noise design improves insurrounding areas

1. Thenoise-suppressing winglet fanisaresultofnewresearch

intovanedesign theory. Theuniquecurvedshapesuppresses the

generation ofvortexes, thusreduces airflownoise.

2. Theadoption ofdouble-orifice ringsreduces airpassage

resistance.

3. Strengthening ofthenoise insulation materialsinthe

compressor and thesealing-inofmechanical noise allows

vibration noise tobegreatlyenclosedand suppressed.

4. Theheat exchangerhas anL-shapeddesign toallowairtoflow

moresmoothly.
