A standard fan coil unit consists of the following key components:
Fan: Circulates air through the unit for heat exchange.
Coil: Transfers heat between water and air. It can be single or double pipe (heating/cooling).
Filter: Removes dust and debris to maintain indoor air quality.
Drain pan: Collects condensation from cooling operations.
Control system: Thermostats or controllers regulate fan speed and water flow.
Fan: Ensures continuous airflow and enhances heat transfer via forced convection.
Coil: Acts as the medium for thermal exchange, compatible with hot or chilled water systems.
Filter: Protects coil efficiency and improves air quality.
Control system: Adjusts temperature and airflow for optimal comfort.
Improved energy efficiency
Easier troubleshooting and maintenance
Extended service life of HVAC systems
Fan coil units are ideal for water-based HVAC systems in:
Multi-story apartments
Hotels and resorts
Office buildings
Hospitals
Inspect and clean filters regularly.
Check water valves and coil for leaks.
Monitor fan operation to avoid airflow reduction.
