Floor Ceiling Type Fan Coils

Fan coil system can be described as a system, through which heating or cooling fluid runs and which provides the desired temperature as a result of the heat transfer between fan supported serpentine and the space.

Fan coil unit is a heating-cooling element equipped with a finned battery on top and a radial fan and filter which provide air movement at the bottom. They are used in central systems to air-condition certain rooms or certain volumes. Fan coil units are generally composed of a fan, a battery and connected equipment. Either hot or cold water passes through the battery. When hot water passes through the system, it provides heat and when the water is cold, cooling is provided. Room thermostats are used to control fan coil units. Fan coil units are used in every space where heating and cooling is needed. Fan coil systems are central systems. They are preferred in various places from houses to big shopping malls, sports halls, residences and public buildings. Fan coil units provide heating or cooling in proportion to hotness or coolness of the water running through them. Capacities of fan coil units vary in respect to the space they will be used.

Silent operation is extremely important for fan coil units and it should be particularly noticed when comparing different units. In addition, medium speed ones should be selected in projects. Project design criteria should be taken into consideration in selection of fan coil units. Hot water is generally supplied to fan coil units by hot-water boilers or steam boilers via an exchanger or all kinds of heat generators and cold water is supplied by chiller groups or heat pumps. Although the installation cost of fan coil systems is high, their operating expenses are rather reasonable. When fan coil units are used together with a heat pump or heat pump chiller, they function as heater in winters and coolers in summers like air-conditioners. Fan coil installation partly resembles installation of a central heating system but calculations are different. Heating capacity of fan coil units is higher than their cooling capacity. As engineering calculations are based on the most critical value, cooling values are taken into account in calculations. Climatic values are also effective in this selection. If cooling load is high in the zone, cooling values are taken as critical values. If heating load is high in the zone, heating values are taken into account. Behaviors of conveying liquid are also important in system details for heating and cooling.

All pipes in the fan coil line should be heat insulated. Pipe diameters of a fan coil system are chosen in accordance with heat load. Diameter selection should be based on the capacity of the fluid, length of the line, resistors on the line, and the velocity of air. One of the most important points in a fan coil system is the drainage system. Slope of drainage lines should allow water to flow easily and they should not be blocked. Maintenance of fan coil units is very important in terms of silent and efficient operation and hygiene. People who work in environments where the fan coil units are not serviced face with health problems. Fan coil units are grouped as wall type, cassette type, floor-ceiling type and ducted type.
