Description

Technical Field

[0001] The utility model relates to the technical field of fan coil units, in particular to a fan coil unit device applied to a large space. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, the quality of indoor environment has received more and more attention. Fan coil units are suitable for large commercial places such as airport terminals and railway station waiting buildings due to their compact structure, relatively high energy efficiency and good air conditioning performance. Although the traditional fan coil units used in large spaces can adjust the indoor temperature, there are still many shortcomings in the use process. For example, the traditional fan coil unit is fixed on the ceiling in a concealed manner, which has the defect of difficult maintenance. When maintenance or repair is required, it is necessary to find a suitable inspection port. When the coil needs to be replaced, it is almost impossible to disassemble and assemble the fan coil without destroying the ceiling decoration, and it is also difficult to clean the dust on the fan coil fins. In short, concealed fan coil units increase the difficulty and complexity of maintenance.

[0003] Due to the characteristics of cold air sinking and hot air rising, the fan coil units concealed on the ceiling of large spaces are located at a higher position. When cooling, the cold air blown out by the fan coil unit will exchange a lot of energy with the indoor air when reaching the appropriate height for the human body, which will not only affect the indoor comfort, but also increase the energy consumption of the fan coil unit; while when heating, the hot air blown out by the fan coil unit will rise directly, and the energy consumption demand of the fan coil unit will be even greater.

[0004] Exposed fan coil units can be placed on the ground and can quickly adjust the air quality of a large space. However, existing exposed fan coil units are prone to inhaling dust and hair from the ground during use, and the filter material replacement process of the fan coil unit is cumbersome and inconvenient for users to operate. This often results in users being unable to replace the filter in time, which greatly reduces the effectiveness of the fan coil unit.

[0005] Therefore, it is necessary to improve the existing fan coil unit device used in large spaces to overcome the defects of the prior art. Utility Model Content

The door panel 2 is hinged to the main body 1, so that the door panel 2 can be easily opened and closed, thereby facilitating the installation and replacement of the filter structure 8 in the mounting cavity. The fan coil unit of the present application can be directly placed on the ground of a large space through the support seat 11, and has the advantages of easy installation, simple maintenance, and energy efficiency.

[0041] In addition, by setting a mounting cavity at the return air outlet at the bottom of the main body of the fan coil unit and snapping the filter structure 8 into the mounting cavity, the installation and replacement of the filter structure 8 becomes convenient. The user only needs to open the door panel 2 to easily remove and replace the filter structure 8 without disassembling the entire fan coil unit or performing complicated operations, thereby reducing maintenance costs and difficulties. In addition, since the filter structure 8 is designed to be snapped into the mounting cavity, it is firmly fixed and not easy to fall off or shift, ensuring the stability and durability of the filtering effect.

[0042] In addition, a filter structure 8 is clamped in the installation cavity. The filter structure 8 is made of high-efficiency filter materials, such as activated carbon, HEPA, etc., which can effectively intercept harmful substances such as dust, bacteria, viruses, etc. in the air, ensuring that the air entering the fan coil unit reaches a high degree of cleanliness. This design can not only improve the air cleanliness of the use area, but also provide users with a healthy and comfortable living and working environment.

[0043] In a more preferred embodiment, a locking structure 7 is provided at the opening edge of the installation cavity for fixing the filter structure 8. The locking structure 7 includes a mounting seat 71 and a locking rod 72. The mounting seat 71 is fixed to the side wall of the installation cavity.
