Description

Technical Field

[0001] The invention belongs to the technical field of humidifiers, and in particular relates to an ultra-thin fan coil unit that is easy to clean. Background Art

[0002] The fan coil unit is referred to as fan coil. It is one of the terminal devices of the air-conditioning system composed of a small fan, an electric motor and a coil. When chilled water or hot water flows through the coil, 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 cooling and heating terminal device. The fan coil can create an indoor air environment suitable for human comfort, meet the indoor air environment required by process production, and eliminate harmful gases in the room and concentrated heat and humidity.

[0003] A Chinese patent discloses a fan coil unit (CN114294711B), comprising: a fan and an air guide structure, the air guide structure comprising: an annular outer shell and at least one annular inner shell, a connecting air duct and at least one converging air duct and at least one connecting port, the connecting port connects the connecting air duct and the converging air duct formed by the corresponding inner shell, and is configured to guide the airflow in the connecting air duct to flow toward the outlet end of the converging air duct; wherein the inner shell comprises a main body, and the main body comprises a tapered section, a waist section and a gradually expanding section connected in sequence. In addition to being able to avoid the size limitation of the centrifugal fan and thus being thinner, the fan coil unit of the present application can also form two low-pressure or even vacuum zones in the converging air duct by introducing external air from the induced draft duct and setting the shape of the inner shell, thereby inducing a large amount of external air to flow into the converging air duct from the inlet end and being discharged after heat exchange by the heat exchange device. As the current fan coil units are used for a longer time, dust will gradually accumulate inside, thereby reducing the air outlet and air intake effects of the fan coil units, and further reducing the working efficiency of the fan coil units. As time goes by, the fan coil units need to be regularly inspected and maintained. Most of the existing structures are too complicated and inconvenient to inspect and clean.
