Therefore, the through-air duct 300 can be connected from the rear end. The air introduction port 301 and the upper end air introduction port 302 introduce air at the same time. The air introduction range of this embodiment is expanded, and the air introduction volume is greatly increased, which can increase the air volume of the non-heat exchange air in the mixed air, so that the temperature of the mixed air is more gentle and comfortable. At the same time, Due to the increase of the induced air volume, the fluidity of the indoor air can also be improved, and the indoor temperature can be adjusted quickly and evenly. Both the air inlet 301 and the air outlet 303 at the rear end are strip-shaped.

Fully mixed inside to further ensure the uniformity of the mixed air and improve the comfort and uniformity of the air supply.

In order to further improve the air induction effect, the structure of the through-air duct 300 is optimized. The inner diameter of the through-air duct 300 from the rear air introduction port 301 to the air supply port 303 is first tapered and then gradually expanded, and the air outlet is located on the gradual expansion section. , the air from the air outlet will not interfere with each other, which expands the air outlet angle and air supply distance. At the same time, the negative pressure area B is formed between the first air outlet 103, the second air outlet 203 and the air outlet 303, under the action of negative pressure, the air outside the first air conditioner body 100 and the second air conditioner body 200 passes through the rear end The air introduction port 301 enters the through-air passage 300, first passes through the tapered section, and then passes through the gradual expansion section, so that the wind speed of the non-heat exchange air in the through-air passage 300 can be increased, and the wind-inducing effect can be improved.

The setting of the position of the air outlet in this embodiment makes it possible for the air outlet direction of the first air outlet and the second air outlet to be in the same direction, and the air outlets of the first air outlet and the second air outlet do not intersect, and will not affect and interfere with each other. It is beneficial to reduce the wind resistance and noise caused by the mutual influence of the two air outlets, and is beneficial to air supply, and the air supply angle and the air supply distance are both improved.

A connecting line intersects the second connecting line where the front end L21 and the rear end L22 of the second air conditioner body 200 are located, and the distance between the front end L11 of the first air conditioner body 100 and the front end L21 of the second air conditioner body 200 is greater than that of the first air conditioner body The distance between the rear end L12 of 100 and the rear end L22 of the second air-conditioning body 200; thus, the first air-conditioning body 100 and the second air-conditioning body 200 gradually expand from the air inlet direction of the through air duct 300 to the air supply direction, increasing Increased air supply angle and air supply distance. Preferably, the included angle between the first connecting line and the second connecting line is greater than 0 degrees and less than or equal to 45 degrees, between which angles, the balance between the air induction effect, the air supply angle and the air supply distance can be achieved.

Certainly, the first connecting line where the front end L11 and the rear end L12 of the first air conditioner body 100 are located is parallel to the second line where the front end L21 and the rear end L22 of the second air conditioner body 200 are located, and the front end L11 of the first air conditioner body 100 is parallel to the The distance between the front end L21 of the second air conditioner body 200 is equal to the distance between the rear end L12 of the first air conditioner body 100 and the rear end L22 of the second air conditioner body 200 , which is also within the protection scope of the present invention.

In this embodiment, the first air outlet 103 of the first air conditioner body 100 and the second air outlet 203 of the second air conditioner body 200 are both located in the through-air passage 300 and close to the air supply port 303 , and the wind blown out by the first air outlet 103 is directed toward The air blown from the air outlet 303 and the second air outlet 203 is directed toward the air outlet 303, the wind blown from the first air outlet 103 and the second air outlet 203 will not interfere with each other, the air supply angle and the air supply distance are greatly improved, which is beneficial to the indoor air. flow.

In addition, the air inlet is located on the outer side of the air conditioner body, and the air outlet is located in the through-air duct, that is, on the inner side of the air conditioner body. The air intake is inhaled, which is conducive to the flow of indoor air and can quickly and evenly adjust the indoor temperature. Certainly, when the number of air-conditioning bodies is more than two, in order to form a through-flow passage between two adjacent air-conditioning bodies, the position of the air inlet 202 needs to be arranged on the rear side of the air-conditioning bodies.

The first air-conditioning body 100 and the second air-conditioning body 200 are arranged symmetrically. The first air-conditioning body 100 and the second air-conditioning body have a symmetrical plane. The plane formed by the midline. The symmetrical arrangement of the first air conditioner body 100 and the second air conditioner body 200 means that the shapes of the first housing 101 and the second housing 201 are symmetrical on the plane of symmetry, and the first air inlet 102 on the first housing 101 and the second housing The second air inlet 202 on the body 201 is symmetrical with the plane of symmetry, the first air outlet 103 on the first casing 101 and the second air outlet 203 on the second casing 201 are symmetrical with the plane of symmetry, the first casing The first air passage 105, the first cross-flow fan 104, the first heat exchanger 106 in the 101 and the second air passage 205, the second cross-flow fan 204, the second heat exchanger 206 in the second housing 201 and The symmetrical plane is symmetrical to further improve the uniformity of air induction, air mixing and air supply.
