Fan coil system design.

The terminal units are usually mounted either under the window or in a ceiling void from which a number of supply outlets can be served. The thermostat controls the fan speed and or the throughput of. Fcu stands for fan coil unit but often engineers will just call them a fan coil to save time. Fan coil units are very common in all types of buildings from offices bars canteens even some homes and apartments will have a fan coil unit in them.

Generally they are connected to the ductwork that supplies air to and extracts air from the interior and.

A fan coil unit fcu also known as a vertical fan coil unit vfc is a device consisting of a heat exchanger coil and a fan as part of an hvac system found in residential commercial and industrial buildings a fan coil unit is often connected to ductwork and a thermostat to regulate the temperature of one or more spaces. The main source of noise in a fan coil is the small fan that circulates air through the coil and into the conditioned space.

Fan coil engineering fan coil engineeringe2 introduction properties of coils and coil design fan coil units can be used to introduce outdoor air into a space circulate and filter air within a space and provide heating and or cooling within a space. The basic components of a fan coil unit are a heating cooling coil fan section and a filter. In the latter case the ceiling void can be used. Figure 13 9 gives measured sound power levels at several rates of flow.

In this article we are going to be looking at fcu s. When a fan coil unit is located above a t bar ceiling the noise it generates is difficult to control even with lined ductwork or silencers.
