DC Brushless Fan Coil

A DC brushless fan coil is a type of fan coil unit that uses a brushless DC motor to power the fan. The motor is more efficient and has a longer lifespan compared to traditional AC motors with brushes. The fan coil unit is commonly used in HVAC systems to distribute cool or warm air throughout a building. The DC brushless fan coil is designed to provide quiet and energy-efficient operation, making it a popular choice for commercial air conditioning and residential AC applications.



1. Efficient and energy-saving:

(1) Although the power of a single fan coil unit is small, it cannot be ignored in the practical application of central air conditioning systems due to its large number of uses. In actual projects, the energy consumption of fan coil units generally accounts for about 20% to 30% of the total energy consumption of air conditioning systems.


(2) Midea DC brushless fan coil adopts a DC brushless motor, with a motor efficiency of up to 90%. Compared with traditional fan coil units, the energy consumption of DC brushless fan coil units can be reduced by about 70% under fixed supply air volume conditions.


(3) In addition, the heat exchanger of Midea DC brushless fan coil adopts high-quality copper tubes, paired with high-efficiency corrugated hyperbolic windowed hydrophilic aluminum fins, optimized flow path design, and uses precision mechanical expansion technology, resulting in high heat exchange efficiency.



2. Quiet and low noise:

(1) The centrifugal fan wheel of Midea DC brushless fan coil is made of lightweight materials, effectively reducing noise.


(2) The centrifugal fan adopts a large air volume and wide impeller, which has been optimized to achieve the best aerodynamic performance of the fan. It improves the air volume and pressure, reduces airflow leakage between the fan and the volute, and has a peaceful sound quality and low noise.


(3) The unique vibration reduction design of bearings reduces the vibration of the fan during operation.
