Composition and key components of fan coil unit system

The fan coil unit consists of the following core components, which work together to ensure efficient operation of the system:

Heat exchanger (coil)
Adopting copper tube and aluminum fin structure to increase heat exchange area and improve heat exchange efficiency.
The number of coil rows (such as second row and third row) directly affects the heat transfer performance. The more rows, the stronger the cooling/heating capacity.
Fan and motor
The fan drives air circulation through the rotation of the impeller, and the motor provides power and supports multi speed regulation (high, medium, low) to adapt to different load requirements.
The rationality of the matching between the motor and the fan directly affects the noise level. High quality products can control the noise level at 30-40 decibels (during low-end operation).
Water receiving tray and drainage system
The water collection tray collects condensed water on the surface of the coil and discharges it outdoors through the drainage pipe to prevent leakage.
The drainage slope should be ≥ 1% to ensure smooth drainage and avoid the growth of bacteria or damage to equipment caused by accumulated water.
Filters and exhaust valves
The filter intercepts dust in the air to prevent dust accumulation on the coil from affecting heat transfer efficiency.
The exhaust valve removes air from the system to prevent air blockage and poor water flow.
Control panel and valves
Control panel adjusts fan speed, temperature settings, and mode switching.
Valves (such as electric two-way valves) control the flow of water to achieve on-demand cooling/heating and reduce energy consumption.
