Product Description
A fan coil unit (FCU) is a device that is mounted on the ceiling and consists of a fan and a coil for heating or cooling. It is an integral component of HVAC systems and can be found in various types of buildings, including residential, commercial, and industrial.
Fan coil unit (FCU) will generally consist of the following components：
Cased or Uncased [casing around unit]
Air Intake
Filter
Fan
Cooling Coil [water/dx]
Heating Coil [water/electric]
Discharge
Grille [intake/discharge]
Speed controller/on/off switch
Duct/Wall mounted thermostat
Modulating/on/off valve
Fan Coil Unit Schematic Diagram [Typical 2 pipe]
The diagram below depicts a standard pipework configuration for a two-pipe fan coil unit, accompanied by an explanation of the two-pipe system.
The two-pipe system is the fundamental and simplest form of design and installation for a fan coil unit, and it offers three possible configurations.
Cooling Only
Heating Only
Cooling or Heating
Cooling Only
A cooling-only unit will only be supplied by chilled water to the coil, and these are usually found installed in spaces where no heating is required throughout the year.
Usually found in hotter climates and small computer/server rooms.
Heating Only
Similar to the cooling-only system, the unit will be only supplied by hot water to the coil, and these are usually found installed in spaces where no cooling is required throughout the year.
Usually found in colder climates.
Cooling or Heating
The cooling or heating option is entirely dependent on the time of year, in the summer, the central chilled water system will feed the 2 pipe systems and coil, whilst in the winter, it will switch over and be fed by the central heating system.
Fan Coil Unit Schematic Diagram [Typical 4 pipe]
Below is a typical pipework configuration for a four [4] pipe fan coil unit, along with a description provided underneath.
The four [4] pipe system employs two [2] coils within the FCU, one for cooling and one for heating. This configuration offers significant advantages as it eliminates the need for seasonal changeovers and allows for automatic temperature management within the space.
The FCU is connected to both the central heating and central chilled water systems concurrently. Control valves within each system regulate the supply of appropriate temperatures to the FCU.
