Description

Technical Field

[0001] This utility model relates to the field of air-conditioning technology, specifically to an air-conditioning unit. Background Technology

[0002] See Figure 1 In existing chilled water type air-wall air conditioning units, because the electrical box 101 and the fan 102 are located on the same side of the unit, the electrical box 101, located in the center of the unit, causes the airflow that passes through the rear coarse filter and then flows through the surface cooler 103 to be at a perpendicular angle to the position of the electrical box. This distribution design affects the utilization of the heat exchange airflow from the return air side, making it difficult for the heat exchange airflow at the same height as the electrical box 101 to be blown out, affecting the heat exchange efficiency of the surface cooler 103 inside the unit, and resulting in a reduction in the unit's energy efficiency. However, due to the limitations of the arrangement of the electrical box 101, it is not easy to install the electrical box 101 in other positions on the same side as the fan 102. Utility Model Content

[0003] The purpose of this invention is to provide a wind-wall air conditioning unit that can avoid the turbulence of airflow inside the unit caused by the obstruction of the electrical box, which would lead to poor heat exchange efficiency and affect the unit's energy efficiency.

[0004] To achieve the above objectives, this utility model provides a wall-mounted air conditioning unit, including a housing, a first fan module, a second fan module, a surface cooler, and an electrical box. The first fan module, the second fan module, and the electrical box are all disposed on the front side wall of the housing. The first fan module and the second fan module are arranged along a first direction, and the electrical box is located between the first fan module and the second fan module. The surface cooler is located inside the housing. The airflow entering the housing is heat-exchanged by the surface cooler and then sent out through the first fan module and the second fan module. The electrical box is inclined relative to the first direction. The electrical box is provided with a top wall panel and a rear wall panel. The rear wall panel is positioned towards the surface cooler, the top wall panel is inclined towards the first fan module and guides the airflow towards the first fan module, and the rear wall panel is inclined towards the second fan module and guides the airflow towards the second fan module.

[0005] As can be seen from the above scheme, by tilting the electrical box so that the top wall panel is tilted towards the first fan module and guides the airflow towards it, and the rear wall panel is tilted towards the second fan module and guides the airflow towards it as well, the top and rear walls of the electrical box act as baffles. This guides the heat exchange airflow from the return air side, which passes through the surface cooler, to the fan module, where it is then blown out with the subsequent airflow. This avoids turbulence in the heat exchange airflow within the unit and improves the heat exchange efficiency. Compared to existing schemes where the return airflow is perpendicular to the rear wall of the electrical box, which can easily lead to instability in the parallel airflow from the surface cooler to the fan, resulting in low heat exchange efficiency, this air-wall air conditioning unit does not require changes to the electrical box structure. Simply tilting the electrical box achieves a good airflow guiding effect, thus improving heat exchange efficiency and overall unit energy efficiency without increasing costs.

[0006] A preferred arrangement is that the top wall panel is perpendicular to the rear wall panel or at an obtuse angle.

[0007] Therefore, the top and rear wall panels can be set vertically to facilitate the rational arrangement of internal components, or they can be set at an obtuse angle to improve the drainage effect.

[0008] A preferred embodiment is that the outer surface of the top wall panel is provided with at least one of a wiring plate and a fixing hook.

[0009] Therefore, by tilting the electrical box, the space above the top wall of the electrical box can be increased, achieving a certain capacity expansion effect. This space can be used to install wiring boards and fixing hooks, thereby saving internal space in the electrical box. Filter boards, reactors, and other components can be placed inside the electrical box according to the needs of subsequent units.

[0010] A further option is to position the wiring board near the first edge of the top wall panel, with the first edge located downstream of the top wall panel in the direction of airflow.

[0011] Therefore, placing the wiring panel on the downstream side of the top wall panel can avoid interference with airflow.

[0012] A further option is to place the wiring board near the first side edge of the top wall panel, with the first side edge located at the end of the top wall panel in the second direction, and the second direction, the first direction, and the airflow direction being perpendicular to each other.

[0013] Therefore, placing the junction box at the end of the junction box line can also avoid the junction box interfering with the airflow.

[0014] A preferred embodiment is that the first fan module includes two or more first fans, wherein at least two of the first fans are arranged along a second direction, and the second direction, the first direction, and the airflow direction are mutually perpendicular to each other.

[0015] A further option is that the second fan module includes two or more second fans, with at least two of the second fans arranged along a second direction.

[0016] Therefore, both the first fan module and the second fan module can include multiple fans, thereby improving air delivery efficiency.

[0017] A preferred embodiment is that an air inlet is provided on the rear side wall of the housing, and an air outlet is provided on the front side wall of the housing, with the first fan module and the second fan module located at the corresponding air outlets.

[0018] A preferred approach is that the first direction is parallel to the vertical direction.

[0019] A preferred design is that the normal to the surface cooler is perpendicular to the direction of airflow. Attached Figure Description

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0030] See Figures 2 to 4 The air conditioning unit includes an outer casing 1, a first fan module 2, a second fan module 3, a surface cooler 4, and an electrical box 5.

[0031] The first fan module 2, the second fan module 3, and the electrical box 5 are all mounted on the front side wall 11 of the outer casing 1. An air inlet 121 is provided on the rear side wall 12 of the outer casing 1, and an air outlet 111 is provided on the front side wall 11 of the outer casing 1. The first fan module 2 and the second fan module 3 are respectively located at the corresponding air outlet 111. An electrical box mounting slot is provided on the outer casing 1. The electrical box 5 can be fitted into the electrical box mounting slot by interference fit, or it can be fixed into the electrical box mounting slot by fasteners or screws.

[0032] The first fan module 2 and the second fan module 3 are arranged along the first direction Z, and the electrical box 5 is located between the first fan module 2 and the second fan module 3. The surface cooler 4 is located inside the outer casing 1 and is arranged vertically. The airflow entering the outer casing 1 is heat-exchanged by the surface cooler 4 and then sent out through the first fan module 2 and the second fan module 3. The normal of the surface cooler 4 is perpendicular to the airflow direction Y.

[0033] Relative to the first direction Z, the electrical box 5 is inclined. The electrical box 5 has a top wall panel 51 and a rear wall panel 52 that are perpendicular to each other. The rear wall panel 52 faces the surface cooler 4. The top wall panel 51 is inclined towards the first fan module 2 and guides airflow towards the first fan module 2. The rear wall panel 52 is inclined towards the second fan module 3 and guides airflow towards the second fan module 3. In other embodiments, the top wall panel 51 and the rear wall panel 52 may also be arranged at an obtuse angle.

[0034] The first fan module 2 includes two or more first fans 21, wherein at least two first fans 21 are arranged along the second direction X, and the second direction X, the first direction Z, and the airflow direction Y are mutually perpendicular. The second fan module 3 includes two or more second fans 31, wherein at least two second fans 31 are arranged along the second direction X. Optionally, in this embodiment, the number of both first fans 21 and second fans 31 is four, with the four first fans 21 arranged in two rows and two columns, and the four second fans 31 arranged in two rows and two columns. In this embodiment, the first direction Z is parallel to the vertical direction, and the second direction X is parallel to the horizontal direction. The number of air outlets 111 is eight, and each fan is correspondingly set with an air outlet 111.

[0035] In other embodiments, the outer surface of the top wall panel may also be provided with at least one of a wiring board and a fixing hook. The wiring board is disposed near a first side edge of the top wall panel, the first side edge being located downstream of the top wall panel in the airflow direction; alternatively, the first side edge may also be located at the end of the top wall panel in a second direction. By tilting the electrical box, the space above the top wall panel of the electrical box can be increased, achieving a certain capacity expansion effect. This allows the wiring board and fixing hook to be disposed in this space, thereby saving internal space within the electrical box. Filter boards and reactors, among other components, can then be placed inside the electrical box according to the subsequent unit requirements.

[0036] As can be seen from the above, by tilting the electrical box, the top wall panel is tilted towards the first fan module, guiding the airflow towards it, and the rear wall panel is tilted towards the second fan module, also guiding the airflow towards it. This allows the top and rear walls of the electrical box to act as deflectors, guiding the heat exchange airflow from the return air side through the surface cooler to the fan module, where it is then blown out with the subsequent airflow. This avoids turbulence in the heat exchange airflow within the unit and improves the unit's internal heat exchange efficiency. Compared to existing solutions where the return airflow is perpendicular to the rear wall of the electrical box, which can easily lead to instability in the parallel airflow from the surface cooler to the fan, resulting in low heat exchange efficiency, this air-wall air conditioning unit does not require changes to the electrical box structure. Simply tilting the electrical box achieves excellent airflow guidance, thus improving heat exchange efficiency and overall unit energy efficiency without increasing costs.

[0037] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
