Description

Technical Field

[0001] The utility model belongs to the technical field of fan coil units, and in particular relates to a fan coil unit which is convenient 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, which is composed of a small fan, an electric motor and a coil (air heat exchanger). 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 cooling and heating terminal device.

[0003] Since the fan coil unit continuously circulates the indoor air for cooling and heating, impurities in the air will also enter the fan coil unit. Although conventional fan coil units are equipped with filters to filter impurities in the air, this cannot completely remove impurities. Therefore, with long-term use, the coils in the fan coil unit will absorb more impurities and dust, which will form precipitation on its surface over time, greatly affecting the contact and heat exchange between the air and the coil, which is not conducive to the normal and stable operation of the fan coil unit and needs to be improved.
