Real time photos of fan coil units

Fan CoilThe unit is abbreviated as fan coil unit. It is one of the end devices of the air conditioning system composed of small fans, electric motors, and coils (air heat exchangers). When chilled water or hot water flows through the coil tube, it exchanges heat with the air outside the tube, cooling, dehumidifying, or heating the air to regulate indoor air parameters. It is a commonly used end device for cooling and heating.

1. The inlet cold water temperature of the fan coil unit should not be lower than 5 ℃, otherwise it may cause condensation of the unit; The temperature of the incoming hot water should not exceed 80 ℃ (usually 60 ℃), otherwise it may cause corrosion of the copper pipes of the unit heat exchanger.
   2. It is recommended that the operating environment temperature for fan coil units be 16-36 ℃ for cooling and 10-30 ℃ for heating; The relative humidity of the air is ≤ 90%.
   3. The fan coil unit is only used for comfort air conditioning and should not be used in special occasions.
   4. Do not install fan coil units in areas with corrosive gases.

   

   2. According to the structural form, it can be divided into vertical, horizontal, wall mounted, card type, etc. Among them, vertical is further divided into column type and low rise type; According to the installation method, it can be divided into open installation and concealed installation; According to the water inlet direction, it is divided into left and right types. All wall mounted fan coil units are surface mounted units with compact structure and good appearance, directly hanging above the wall. Card type (ceiling embedded) unit, with beautiful air inlet and outlet exposed under the ceiling, and fans, motors, and coils placed above the ceiling, belongs to semi exposed unit. Surface mounted units all have beautiful shells, with built-in air inlets and outlets, and are installed in the room in a visible manner. The shell of the concealed unit is generally made of galvanized steel plate.

   As the terminal equipment of central air conditioning, the quality of fan coil units determines the indoor air conditioning effect. Meanwhile, fiberglass centrifugal fans, cabinet centrifugal fans, 4-72 centrifugal fans, and centrifugal fans are also supporting equipment for central air conditioning.
