A fan coil unit (FCU) is a compact HVAC device that provides heating, cooling, and dehumidification by circulating temperature-controlled water. Proper selection involves estimating thermal loads, reserving 20–30% extra capacity for extreme conditions and usage variations, and choosing an installation type suited to the space. This ensures efficient, reliable performance in residential or commercial settings.

Discover the common reasons behind insufficient cooling in fan coil units and learn practical solutions to restore comfort and efficiency in your HVAC system.

Discover why heat pump outlet water temperature is set at 55–60°C. Improve energy efficiency, prevent scaling, and ensure fan coil unit compatibility.

The fresh air ventilation unit is a new type of environmental protection appliance that keeps the indoor air clean and fresh at all times.

Filter ball valve and globe valve maintenance is especially important for fan coil units

A fresh air system is an independent air handling system composed of an air supply system and an air exhaust system. It is divided into ducted fresh air systems and ductless fresh air systems.
