How do fan coil units work?

19
A fan coil unit (FCU) contains a fan which draws the air in a space into the unit then blows it over a cooling or heating coil. FCUs will generally have a chilled water coil for cooling and either a hot water coil for heating or an electric heating element.


Considering this, do fan coil units use refrigerant?

Fan coil units (FCU) consist of only a fan and a heating or cooling element, are located within the space they are serving, and are generally not connected to ductwork. Here, refrigerant is circulated between one or more fan coil units and is connected to an external heat exchanger.

Furthermore, what is the difference between an air handling unit and a fan coil? In simple terms, an air handling unit (AHU) is a component of an HVAC system that cools and distributes air into the space through a duct. A fan coil unit (FCU) is a standalone system that circulates the existing air in a small space, but it can also be a part of an HVAC system.

Also know, how do you service a fan coil unit?

Ensuring Your Preventive Maintenance Checklist Includes Everything

  1. Power off the fan coil unit.
  2. Visually inspect the outside and inside of the unit.
  3. Examine the blower fan for movement, wear and tear and dust.
  4. Change the air filter.
  5. Lubricate all the moving parts, except the ball bearings.

How often should a fan coil unit be serviced?

three months

What is VAV in HVAC?

From Wikipedia, the free encyclopedia. Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant temperature.

What is the purpose of a fan coil unit?

Fan coil units circulate hot or cold water through a coil in order to condition a space. The unit gets its hot or cold water from a central plant, or mechanical room containing equipment for removing heat from the central building's closed-loop.

What is an FTU in HVAC?

What is FTU? Fan Terminal Units (FTUs) provide Variable Air Volume (VAV) air displacement in underfloor air distribution systems. Modular in nature, an FTU is designed to integrate into or below raised access floor panels and force air circulation through the system.

What is a 4 pipe fan coil system?

A four-pipe fan coil unit consists of a fan, chilled water cooling coil, hot water heating coil, and air filter. Fan coil units are designed to provide dehumidification of the area served; however, the amount of dehumidification provided can be limited by increasing the chilled water supply temperature.

What is the difference between HVAC and chiller?

Thermal Care process chillers have independent water and refrigeration circuits. Most HVAC chillers have independent refrigeration circuits, but not independent water circuits. If the water circuit fails on an HVAC chiller, the entire chiller is down causing the entire process to shut down.

How do you clean fan coils?

Coils on most fan coil units can be cleaned by removing the motor/blower assemblies and brushing the entire air face between fins with a stiff brush. Brushing should be followed by a thorough vacuuming.

What is a fan coil filter?

Fan Coil Filters. Protect your Heating and Cooling Coils with Fan Coil Filters. These filters are designed to stop large particles from building up on your Heating/Cooling Coils. The Build up of Dust Particles can reduce the efficiency of your coils. Robust.

How does a VAV system work?

What is a VAV Box? The VAV regulates the volume of the air to the zone by opening or closing the damper, thus controlling the amount of conditioned air directed to the zone. Each zone in a building has a thermostat which controls the VAV, telling it when to open or shut the damper based upon the needs of the zone.

What is the function of fan coil unit?

A fan coil unit (FCU) is a device that uses a coil and a fan to heat or cool a room without connecting to ductwork. Indoor air moves over the coil, which heats or cools the air before pushing it back out into the room.

What is AHU and FCU?

AHU system treats outside air while FCUs basically recycle or re-circulates the air. AHU, completely known as air handling unit is different from FCU or the fan coil unit. AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself.

What is a VRF air conditioning system?

Variable refrigerant flow (VRF), also known as variable refrigerant volume (VRV), is an HVAC technology invented by Daikin Industries, Ltd. in 1982. This refrigerant is conditioned by a single outdoor condensing unit, and is circulated within the building to multiple indoor units.

What is the working principle of chiller?

A chiller works on the principle of vapor compression or vapor absorption. Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°F (10°C).

What happens if AC is not serviced?

The functioning of an air conditioning system is quite simple. If you will not do the regular aircon servicing then dirt and dust will get deposited in its filters. This deposition of dust and dirt in the filters affect its working and your air conditioning system will need to invest more efforts in its working.
