What factors cause Ultra-Thin Concealed fan coil noise
The Guqin Series Vertical and Horizontal Ultra-Thin Concealed Fan Coil Unit is a HVAC terminal component product produced by Yesncer, named after the world’s intangible cultural heritage – the Guqin. Not only does it have an exquisite appearance, but its performance is also elegant and tranquil.
This product has multiple installation methods (wall-mounted, vertical, and horizontal), catering to different installation requirements in diverse working conditions. The machine body thickness is much thinner than common similar machines on the market, measuring only 180mm.
Regarding performance, noise related to fans can be categorized into mechanical layout factors, turbulence factors, and mechanical fatigue and aging factors. Mechanical layout factors are closely related to product design, including the arrangement and layout of fans, wind-cutting devices, air guides, and exhaust ports, as well as material selection. These factors directly determine the baseline noise level of the fan coil unit. Even if other aspects are optimized, poor design in these areas remains a significant issue. In the case of the Guqin Series products, the inherent wind noise is generally below 50 decibels, and for indoor units, especially bedroom models, options with noise levels below 40 decibels are available.
Turbulence factors are also related to the aforementioned layout, but another critical factor is the type, shape, and even material of the fan itself. Common fans typically have blades that directly cut and push air (creating wind). Although the strength of the generated wind varies based on fan size and model, they all follow a direct discharge pattern. In terms of overall indoor air circulation efficiency, this approach is less effective. Facing this type of wind, although slightly better than air conditioning airflow, it can still be uncomfortable, especially for older adults and children.
Taking the example of the Guqin FP-34 Ultra-Thin Concealed Fan Coil Unit, it can circulate the air in a room equivalent to a height of 3.4 meters and an area of 100 square meters within one hour. Moreover, the sound level is only 35 decibels, creating an ideal quiet environment that ensures you can rest or work/study with peace of mind.
