[0008] The technical scheme is realized, that is, the air outlet is arranged on the static pressure box below the connecting wall. The air outlet is provided with a return air panel, that is, after the air flow is sent into the total air inlet cavity, the fresh air in the total air inlet cavity can enter the total air outlet cavity through the first air outlet, and then is sent out from the air outlet, so that the effect of sending air into the room is achieved. When the air volume in the air inlet pipe increases, the air volume regulating valve is opened, so that the excess air volume can enter the branch air inlet cavity through the branch pipe, and then enters the total air outlet cavity through the second air outlet, so that the excess air volume will not be discharged from the first air outlet, thereby preventing the first air outlet from generating noise due to the increase of air volume. At the same time, when the air volume decreases, the branch pipe is closed, so that the air flow is discharged from the first air outlet in the total air inlet cavity into the total air outlet cavity, thereby ensuring the flow rate, and further ensuring the effect of inducing return air by fresh air, and further ensuring the comfort effect of the cold beam.

[0012] The technical scheme is realized, and the air guide plate can ensure that the fresh air is blown out to both sides from the return air panel, and then the blown-out fresh air can induce indoor air to enter the total air outlet cavity from the return air hole and mix with the fresh air, thereby achieving the effect of inducing return air. The entire return air panel is integrally made, so as to facilitate installation and replacement.

[0013] As a preferred scheme of the present application, the air guide plate is provided with a partition plate arranged vertically along the length direction of the air guide plate.

[0014] The technical scheme is realized, so as to ensure that the fresh air is blown out uniformly and the influence of vortex on the air blowing effect is reduced. The partition plate is arranged on the return air panel, so that the entire return air panel is integrally arranged, thereby facilitating installation and processing.

[0016] The above technical solution is implemented to perform end heat exchange on the air flow, and ensure the comfort of the user.

[0017] As a preferred scheme of the present application, the static pressure tank is provided with a wind pressure detector.

[0018] The above technical solution is implemented to detect the cold beam operation in time by the user.

[0019] In summary, the present application has at least one of the following beneficial technical effects:

[0020] When the air volume in the air inlet pipe becomes large, the air volume adjusting valve is opened, so that the excess air volume can enter the branch flow pipe into the branch flow inlet cavity, and then he enters the total air outlet cavity through the second air outlet, so that the excess air volume will not be discharged from the first air outlet, thereby preventing the first air outlet from generating noise due to the increase of air volume. At the same time, when the air volume becomes small, the branch flow pipe is closed, so that the air flow is discharged from the first air outlet in the total air inlet cavity into the total air outlet cavity, thereby ensuring the flow rate, and further ensuring the effect of fresh air induced return air, and further ensuring the comfort effect of the cold beam.

Further, when the flow amount of the air in the air inlet pipe 2 is increased, the flow amount adjusting valve 16 is opened, so that the excess flow amount can enter the branch air inlet cavity 13 from the branch flow pipe 15, and then enters the total air outlet cavity 12 through the second air outlet port 32, so that the excess flow amount is not discharged from the first air outlet port 31, thereby preventing noise from being generated from the first air outlet port 31 due to the increase of the flow amount. Meanwhile, when the flow amount is decreased, the branch flow pipe 15 is closed, so that the air flow is entirely discharged from the first air outlet port 31 in the total air inlet cavity 11 into the total air outlet cavity 12, thereby ensuring the flow rate and further ensuring the effect of inducing return air by fresh air and the comfort effect of the cooling beam.

[0030] The connecting wall 3 comprises two inclined air guide sections 33 that are connected with the air outlet port 4 on both sides, the first air outlet port 31 and the second air outlet port 32 are both divided into two rows corresponding to the two inclined air guide sections, and are arranged in the inclined direction of the corresponding inclined air guide section 33, and the return air panel 5 is arranged centrally between the two inclined air guide sections 33, so that the discharged fresh air is guided by the inclined air guide sections 33, thereby being blown out uniformly on both sides of the return air panel 5, so as to ensure the uniformity of the air outlet effect, thereby ensuring that the fresh air can normally induce return air to enter the total air outlet cavity 12 from the return air panel 5.
