Fan coil unit

Fan coil unit is abbreviated as fan coil. It is one of the end devices of the air conditioning system composed of small fans, 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, so that the air is cooled, dehumidified or heated to adjust the indoor air parameters. It is a commonly used terminal device for cooling and heating.

Fan coil units can be divided into vertical fan coil units, horizontal fan coil units, wall-mounted fan coil units, cassette fan coil units, etc. according to their structural forms. Among them, vertical fan coil units are divided into vertical fan coil units and column fan coil units. Low-profile fan coils; according to the installation method, it can be divided into surface mounted fan coils and concealed fan coils; according to the direction of water intake, it can be divided into left fan coils and right fan coils. The wall-mounted fan-coil units are all surface-mounted units, with compact structure and good appearance, which are directly hung above the wall. Cassette type (ceiling embedded) unit, the more beautiful air inlet and outlet are exposed under the ceiling, and the fan, motor and coil are placed on the ceiling. It is a semi-exposed unit. The surface-mounted unit has a beautiful shell, with its own air inlet and outlet, which are exposed and installed in the room. The shell of the concealed unit is generally made of galvanized steel. Fan-coil units are divided into two categories according to the external static pressure: low static pressure and high static pressure. The outlet static pressure of the low static pressure unit at the rated air volume is 0 or 12Pa, for the unit with a tuyere and filter, the outlet static pressure is 0; for the unit without a tuyere and filter, the outlet static pressure is 12Pa; high The static pressure at the outlet of the static pressure unit at the rated air volume is not less than 30Pa.
