Referring to fig. 1, in the conventional fresh air conditioner, the fresh air pipe usually needs to be routed at the back of the indoor unit body 13 of the air conditioner to take into account the left and right pipe discharging manner. Because the air volume is positively correlated with the pipe diameter, the pipe diameter of the fresh air pipe is large for a large fresh air volume air conditioner, the space between the back of the indoor unit body 13 of the air conditioner and the wall 14 is limited, the structural shape of the back of the air conditioner is complex, the large-pipe-diameter fresh air pipe 11 is difficult to walk behind the air conditioner, and the requirements of a left outlet pipe and a right outlet pipe in different use scenes are difficult to meet.

Referring to fig. 2, in the present embodiment, an original large-diameter fresh air duct 11 is changed into a fresh air duct assembly, the fresh air duct assembly includes a plurality of first air ducts 11a with smaller pipe diameters, an indoor unit body 13 of an air conditioner is hung on a wall 14, when the fresh air duct assembly 10 runs at the back of the indoor unit body 13 of the air conditioner, the mutual positions of the plurality of first air ducts 11a can be adjusted according to the structure at the back of the body to adapt to the back structure of the indoor unit body 13 of the air conditioner and irregular spatial arrangement during running, thereby meeting the requirements of left and right outlet pipes in different use scenes, and improving the compatibility of the fresh air duct assembly 10 during running at the back of the indoor unit body 13 of the air conditioner. For example, a joint can be used at the connection between the first air ducts 11a and the fresh air inlet, so that the first air ducts 11a can be conveniently detached when the positions of the first air ducts 11a are adjusted. Referring to fig. 3, the pipelines of the first air ducts 11a may be all connected in parallel, may be connected in a row (referring to fig. 3a), may be connected in a bundle, or may be connected in other implementable forms (referring to fig. 3 b); when the pipeline needs to be twisted to smoothly pass through the pipeline, in order to avoid the twisting to cause the pipeline to be bent to block the air flow, two groups of pipelines can be connected in parallel (please refer to fig. 3c), and the arrangement directions of the groups can be the same or different, and can be horizontal, vertical or oblique; the connection may be in groups of three (see fig. 3d) or in groups of three or more, the connection forms of the groups may be the same or different, and may be connected in a row or a bundle, or may be connected in other practical forms; or the pipelines of the first air ducts 11a are not connected with each other and are scattered, and the pipes can run in the space between the back of the indoor unit of the air conditioner and the wall 14; it may be a group of two or three or more than two in a scattered way (see fig. 3e), or a group of three or more than three in a scattered way (see fig. 3 f). Referring to fig. 4, since the first air ducts 11a are flexible and are hoses, the lengths of the first air ducts 11a may be the same or different, and may be straight or curved, and the degree of curvature may be the same or different, and finally, the first air ducts 11a pass through the through-holes on the casing of the indoor unit of the air conditioner and extend out of the room.

The plurality of first air pipes 11a are communicated with the fresh air inlet, and the space of the fresh air inlet cannot be efficiently utilized due to gaps between pipe walls of the first air pipes 11a, so that the air volume of the introduced outdoor air is damaged; moreover, the sum of the pipe wall areas of the first air ducts 11a is much larger than that of the second air duct 11b, and when air flows in the first air ducts 11a, the air resistance is large due to friction of the pipe walls, which also causes wind loss to a certain extent. Therefore, in order to reduce the wind loss, a section of second air duct 11b is added between the fresh air inlet and the first air ducts 11a, and the connection mode can be various, for example, the second air duct 11b is connected with the fresh air inlet through an adapter, and is connected with the first air ducts 11a through a buckle, a threaded connection or a connector, and the like. After passing through the first air ducts 11a, the outdoor air is converged into the second air duct 11b, and then enters the fresh air module from the fresh air inlet to the indoor space.

After entering the first air ducts 11a, the outdoor air is converged by the first connectors 12a, enters the second air duct 11b, and enters the fresh air module through the fresh air inlet. In a preferred embodiment, in order to reduce the wind loss, the sum of the overfire air areas of the first air ducts 11a is not less than the overfire air area of the second air duct 11b, and when the number and the diameter of the first air ducts 11a and the diameter of the second air ducts 11b are determined as required, the number and the diameter of the first air ducts 11a and the diameter of the second air ducts 11b can be considered, and then suitable first connectors 12a are selected to communicate the second air ducts 11b with the first air ducts 11 a.

Since the sum of the pipe wall areas of the first air ducts 11a is much larger than that of the third air duct 11c, when air flows in the first air ducts 11a, the air resistance is large due to the friction of the pipe walls, which may cause wind loss to a certain extent. Therefore, in order to reduce the wind loss, the first air ducts 11a are communicated with the outdoor air through the third air duct 11c, and the connection manner between the first air ducts 11a and the third air ducts 11c may be various, for example, by a snap connection, a threaded connection, a connector connection, or the like.
