Description

Technical Field

[0001] This utility model relates to the field of fan coil unit technology, specifically a cassette fan coil unit that is easy to maintain. Background Technology

[0002] A fan coil unit, also known simply as a fan coil unit, is a terminal device in an air conditioning system, consisting of a small fan, motor, and coil (air heat exchanger). When chilled or hot water flows through the coil, it exchanges heat with the outside air, cooling, dehumidifying, or heating the air to regulate indoor air parameters. It is a commonly used cooling and heating terminal device. According to its structure, it can be divided into: vertical, horizontal, wall-mounted, and cassette types, with vertical types further divided into column-mounted and low-profile types. According to the installation method, it can be divided into exposed and concealed installation; according to the water inlet direction, it can be divided into left-hand and right-hand types. Wall-mounted fan coil units are all exposed units, with a compact structure and good appearance, directly mounted on the upper part of the wall. Cassette (ceiling-mounted) air conditioning units have aesthetically pleasing air inlets and outlets exposed under the ceiling, while the fan, motor, and coil are placed above the ceiling. They are semi-exposed units. Exposed units have aesthetically pleasing casings with built-in air inlets and outlets and are installed in the room. Concealed units generally have casings made of galvanized steel sheets. Existing cassette fan coil units have many maintenance inconveniences during use. Their internal components have a complex installation structure. When an internal part malfunctions and needs to be repaired or replaced, it often requires disassembling a large number of related components, which consumes a lot of time and manpower.
