Body performance, fan operating efficiency and air supply range.

Three independent independent centrifugal air duct systems of three or more are separated by their respective air duct profile structures, and the air duct systems are not interconnected with each other, because the front air outlets are also interconnected by the air duct profile structure. It is separated and does not affect each other, so the fan systems arranged in parallel on the upper, middle and lower sides can be independently controlled to open and / or close, so that the front and back can be selectively opened and / or closed according to the experience and activities of users in different indoor locations.

Taking three fans 3 as an example, each fan 3 has double-sided air outlet, and the double-side air outlet direction of the fan 3 is opposite. In this embodiment, air outlets are provided on the upper, lower, left, and right sides of the air inlet 4. Specifically, the air outlet includes a left air outlet 10 and a right air outlet 11, and also includes an upper air outlet 12 and a lower air outlet 13. Among them, there are three left air outlets 10, which are arranged in a vertical direction and each left air outlet. 10 corresponds to the left air outlet of one fan 3, and the right air outlets 11 are three, which are arranged along the vertical direction. Each right air outlet 11 corresponds to the right air outlet of one fan 3.

In the air duct system where the uppermost fan 3 is located, the upper air duct wall is provided with an air passage 17. The air passage 17 is, for example, a slit extending in the thickness direction, so that the air from the uppermost fan 3 is discharged.

In the air duct system where the fan 3 located at the lowermost side is located, the air duct 17 is provided on the wall of the lower air duct. The air passing channel 17 is, for example, a slit extending in the thickness direction, so that the air from the lowermost fan 3 can partially enter the lower air outlet 13 through the air passing channel 17 and blow out through the lower air outlet 13. Ensure that a certain amount of up and down air flow is distributed without affecting the disturbance of left and right air flow, and achieve auxiliary air supply.

An air outlet grille is provided at the air outlet, which on the one hand plays a protective role and on the other hand can play a role of guiding the wind. In this embodiment, the air outlet grilles at the air outlets on the left and right sides extend in the up-down direction, and the air outlet grills at the air outlets on the upper and lower sides extend in the left-right direction.

Because the front panel 5 is provided with air outlets at upper, lower, left, and right positions, and the air outlets are forward-facing, the casing can realize front-side axial multi-face air outlet, so that the vertical temperature difference in the height direction of the indoor space is small, and the air velocity is supplied. The height direction is uniform, which solves the common technical problem of "the hot air cannot be sent down and the cold air cannot go up" at the existing indoor end, and reflects the superiority of cooling and heating comfort.

Because the air-conditioning terminal equipment adopts an embedded arrangement, the maintenance structure indirectly reinforces the terminal equipment. During its operation, the maintenance structure can partially reduce the vibration noise generated by the terminal equipment, which indirectly achieves the purpose of noise reduction.

The end of the air conditioner is embedded in the vertical wall 2.

Since the upper air outlet grille 14 has a guiding effect on the air outlet at the upper air outlet 12, the upper air outlet is deviated in a direction away from the air inlet 4, and the air from the upper air outlet 12 can be prevented from being directly sucked into the air inlet 4, resulting in The air flow of the upper air outlet 12 is short-circuited, so that the air from the upper air outlet 12 can sufficiently flow through the room to adjust the temperature of the room. Similarly, since the down-exit style grille 15 has a guiding effect on the air at the lower air outlet 13, the down-air is deviated in a direction away from the air inlet 4, and the air from the down air outlet 13 can be prevented from being directly directed to the air inlet 4 Inhalation causes a short-circuit of the airflow from the lower air outlet 13, so that the air from the lower air outlet 13 can sufficiently flow through the room to adjust the temperature of the room. By directing the airflow directions of the upper and lower airflows, it is possible to effectively prevent the short circuit of the airflows in and out, form an effective temperature adjustment effect, and improve user comfort.

The method is changed to three or more fan systems arranged in parallel on top, middle and bottom. The heat exchanger is located between the front air inlet and the fan system. This can ensure the uniformity of the wind speed distribution on the heat exchanger and improve The whole machine heat exchange capacity. Driven by the power of the fan, the indoor air flows in axially through the air inlet area extending laterally in the middle of the front panel of the housing. Under the pressure of the shell, it is sent out axially from the multiple air outlets on the periphery of the air intake area on the front of the shell, and it is circulated to the room. To improve user experience comfort.

This technical solution increases the heat exchange area of the refrigeration system while simultaneously drawing and blowing the airflow in the air duct to the heat exchanger, making the air velocity distribution on the heat exchanger at the air inlet and outlet more uniform, and improving the heat exchange efficiency of the heat exchanger. At the same time, the parameters (wind speed, wind temperature, etc.) of the indoor environment flow field are more uniform, and the user comfort is improved.

Referring to FIG. 10 in combination, according to the fourth embodiment of the present application, it is basically the same as the first embodiment, except that in this embodiment, the heat exchanger 16 is provided corresponding to the air outlet, and is located on the left side. The heat exchanger 16, the heat exchanger 16 on the right side, the heat exchanger 16 on the upper side, and the heat exchanger 16 on the lower side are arranged in parallel, and the heat exchanger 16 is not provided at the air inlet.
