A fan coil unit (FCU) is a device that cools or heats a room through a fan and coil. In this blog we are discussing what they are, their work process, and how to do fan coil unit maintenance from the eyes of one of the best fan coil unit manufacturers.
Here is a close look at a fan coil unit.
There are different types of FCU. A few FCUs work through ducting while others don’t. Similarly, some FCUs are considered part of the air handler system while others are not. Sometimes they come in horizontal and vertical configurations that could be ceiling mounted, floor mounted, or fixed within a wall.
Several fan coil units are designed for independent working; however, a few are tied-in as an HVAC system’s part. FCUs can be connected to a structure’s automation system inclusive of a thermostat and can be managed on a computer or through a central panel.
Note: the above-mentioned process can a bit different depending on the FCU (either the fan coil unit has two or four pipes).
The fan coil units are massive when you have several small spaces that need individual control. They are also inclined towards coming in at a lower cost point compared to traditional systems. Also, it can be installed as less invasive.
Seeing the negative side, the fan coil units are not as powerful as traditional systems. Also, FCUs lend themselves to cooling and heating large open spaces. They also need hot and chilled water valves that can be a problem for maintenance.
If the fan coil’s motor is vibrating, making odd sounds, or not functioning at all, contact a technician for additional repairs.
