DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0052] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] In the existing full air system, an external pipe is generally connected to the air inlet at the top of the air inlet box. The external pipe introduces outdoor fresh air into the air inlet box, then flows through the air inlet box, and enters the bottom space of the cabinet from the air outlet of the air inlet box and the air inlet of the air handling unit cabinet. The airflow in the bottom space flows to the functional components inside the air handling unit for processing. When installing the air inlet box, there is a problem of insufficient installation space. Since the air handling unit cabinet is pre-fixed on the base, and a large number of components are arranged inside, the weight is large. At the same time, at least one side of the air handling unit cabinet is an openable and closable movable surface for operating the components inside the cabinet, which needs to face the outside. Therefore, there is an urgent need for a solution that can realize the rapid installation of the air inlet box in any space layout without moving or rotating the air handling unit cabinet. In response to this problem, the technicians first solved the problem of insufficient installation space by reducing the size of the air inlet box, changing the direction of the air inlet of the air inlet box, etc. However, these methods bring new problems to the entire air handling unit, such as air intake volume, noise control and aesthetics. Subsequently, the technicians discovered that the bottom of the cabinet and the bottom space could be optimized by opening air inlets on at least two side walls of the cabinet so that the air outlet of the air inlet box can be selectively connected to any air inlet of the cabinet. At the same time, corresponding functional components such as a mounting structure for a filter component are provided at each air inlet in the bottom space to adapt to different choices of the air inlet box outlet for the cabinet air inlet.

[0054] Based on this, the utility model provides a full air system, with air inlets opened on at least two side walls of the cabinet, so that the air outlet end of the air inlet box can be selectively connected to the air inlet of any side wall, and the air inlet not connected to the air inlet box is blocked by a cover plate to ensure the airtightness of the cabinet, so as to avoid the situation where the air inlet box cannot be installed when there is insufficient installation space in a certain direction. It is suitable for installation in various space distributions in practice.

[0055] Please also see Figure 1 2 , an embodiment of the present application provides a full air system, including a cabinet 10, an air inlet box 20 and at least one cover plate 30. The cabinet 10 includes multiple side walls 11, the air inlet box 20 is fixedly connected to the side walls 11 of the cabinet 10, and at least two side walls 11 of the cabinet 10 are provided with air inlets, one of which is conductively connected to the air outlet end of the air inlet box 20, so that the air flow enters the cabinet 10 through the air inlet box 20, and the other air inlets are covered with cover plates 30 for blocking the air inlets that are not connected to the air inlet box 20.

[0056] Specifically, the cabinet 10 includes two opposite side walls 11, which are defined as a first side wall 111 and a second side wall 112, respectively. The first side wall 111 is provided with a first air inlet 111a, and the second side wall 112 is provided with a second air inlet 112a. In this embodiment, the airflow path inside the cabinet 10 is from bottom to top, and the first air inlet 111a and the second air inlet 112a are respectively arranged below the first side wall 111 and the second side wall 112 at the bottom of the cabinet 10.

[0057] It is understandable that the cabinet 10 is provided with a surface cooler and a refrigerant pipeline (not shown). Since the surface cooler inside the cabinet 10 needs to be filled with new refrigerant and the old refrigerant needs to be discharged, the refrigerant pipeline needs to be connected to the outside to facilitate the access and discharge of the refrigerant. Therefore, at least two side walls 11 of the cabinet 10 are provided with water receiving holes. The water receiving holes on the side wall 11 fixedly connected to the air inlet box 20 are in a blocked state, and the other water receiving holes are connected to the refrigerant pipeline. In this embodiment, the first side wall 111 is provided with a plurality of first water receiving holes 111b, and the second side wall 112 is provided with a plurality of second water receiving holes 112b. Multiple first water receiving holes 111b and multiple second water receiving holes 112b can be respectively arranged at any positions of the first side wall 111 and the second side wall 112. Preferably, the first water receiving holes 111b and the second water receiving holes 112b are symmetrically arranged on the first side wall 111 and the second side wall 112, which is beneficial for better fixing of the air inlet box 20 when it is installed on any side wall 11; at the same time, multiple first water receiving holes 111b or multiple second water receiving holes 112b are concentratedly arranged, which is beneficial for the arrangement of external pipes.

[0058] The air outlet of the air inlet box 20 can be selectively connected to the first air inlet 111a or the second air inlet 112a. When the air outlet of the air inlet box 20 is connected to the first air inlet 111a, the first water receiving hole 111b is in a blocked state, one end of the second water receiving hole 112b is connected to the refrigerant pipeline inside the cabinet 10, and the other end is connected to the external pipeline of the cabinet 10, and the cover plate 30 is covered at the second air inlet 112a.

[0059] When the air outlet end of the air inlet box 20 is connected to the second air inlet 112a, the second water receiving hole 112b is in a blocked state, the first water receiving hole 111b is connected to the refrigerant pipe inside the cabinet 10, and the other end is connected to the external pipe of the cabinet 10, and the cover plate 30 is covered at the first air inlet 111a.

[0060] See also Figure 3When the first water receiving hole 111b or the second water receiving hole 112b is in a blocked state, a blocking member 113 is provided at the first water receiving hole 111b or the second water receiving hole 112b, and the blocking member 113 is inserted into the first water receiving hole 111b or the second water receiving hole 112b. Preferably, the blocking member 113 includes a sealing plate 1131 and a plurality of inserting portions 1132, the plurality of inserting portions 1132 are fixedly provided on one side of the sealing plate 1131, the plurality of inserting portions 1132 are inserted into the corresponding plurality of first water receiving holes 111b or the second water receiving holes 112b, and a side of the sealing plate 1131 provided with the inserting portions 1132 abuts against the first side wall 111 or the second side wall 112, so that the end of the first water receiving hole 111b or the second water receiving hole 112b is not exposed, and the entire side wall 11 is smoother and more beautiful. In another embodiment, there are multiple blocking members 113, and the multiple blocking members 113 are respectively inserted into the multiple first water receiving holes 111b or the second water receiving holes 112b.

[0061] See also Figure 4 The air outlet end of the air inlet box 20 is provided with a bellows air outlet 21, and a first connecting member 211 is arranged around the edge of the bellows air outlet 21, and the first connecting member 211 is fixedly connected to the first air inlet 111a or the second air inlet 112a. Specifically, the bellows air outlet 21 is opened on the outer wall of the air inlet box 20, and the first connecting member 211 protrudes from the outer wall of the air inlet box 20. The shape and size of the first connecting member 211 are matched with the first air inlet 111a and the second air inlet 112a, so that the first connecting member 211 is just inserted into the first air inlet 111a or the second air inlet 112a, which facilitates the conduction connection between the bellows air outlet 21 and the first air inlet 111a or the second air inlet 112a.

[0062] In another embodiment, first connecting members 211 are respectively arranged around the edges of the first air inlet 111a and the second air inlet 112a, wherein one of the first connecting members 211 is fixedly connected to the bellows air outlet 21. Specifically, the first connecting member 211 arranged on the first side wall 111 protrudes from the first side wall 111, and the first connecting member 211 arranged on the second side wall 112 protrudes from the second side wall 112. The size and shape of the first connecting member 211 match the bellows air outlet 21. When the bellows air outlet 21 is conductively connected to the first air inlet 111a, the first connecting member 211 at the edge of the first air inlet 111a is inserted into the bellows air outlet 21. When the bellows air outlet 21 is conductively connected to the second air inlet 112a, the first connecting member 211 at the edge of the second air inlet 112a is inserted into the bellows air outlet 21.

[0063] By arranging water receiving holes and air inlets on at least two side walls 11, and connecting the air inlet box 20 and the cabinet 10, the cover plate 30 and the cabinet, and the sealing member 113 and the water receiving hole in an inserting manner, on the one hand, it is convenient to change the installation position of the air box 20 according to the actual installation space distribution, and on the other hand, when the refrigerant pipe connected to the first air inlet 111a or the second air inlet 112a is blocked during actual use, the air inlet box 20 can be conveniently replaced to other side walls 11 with air inlets at any time for connection, and then the sealing member 113 of the originally blocked water receiving hole can be pulled out, and the external pipe can be connected to the water receiving hole, thereby greatly reducing the difficulty of maintenance when the refrigerant pipe inside the cabinet 10 is blocked.

[0064] See also Figure 5 As a further embodiment, a bellows air inlet 22 is provided at the top of the air inlet box 20. The bellows air inlet 22 is used to connect an external air inlet duct. The external air inlet duct guides the external airflow into the air inlet box 20. During actual installation, the length of the external air inlet duct is different. In order to enable the air inlet box 20 to be quickly and conveniently connected to external air inlet ducts of different lengths, the air inlet box 20 is configured as a height-adjustable box.

Preferably, the second box 24 is inserted into the first opening 23a, and a plurality of screw holes are arranged on the outer walls of the first box 23 and the second box 24 along the sleeve direction. During installation, after the combined height of the first box 23 and the second box 24 is determined according to the length of the external air inlet duct, screws are inserted into the screw holes for fixing.
