It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2As shown, the present invention proposes a fan coil unit, including a housing 1, a fan 2 and a fan direction adjustment device, wherein the housing 1 is provided with a plurality of air outlets, specifically, an upper air outlet 11 is provided on the top thereof, and a side air outlet 12 is provided on the side thereof. The fan 2 is arranged in the housing and can be driven to rotate by the fan direction adjustment device, so that the air outlet of the fan 2 can be adjusted to blow air toward the upper air outlet 11 of the housing 1 or toward the side air outlet 12 of the housing. Thus, the position of the air outlet of the fan coil unit can be changed, which improves the flexibility of the actual engineering installation of the product, greatly reduces the installation cost, and improves the user experience.

[0022] In the present invention, the air outlet of the housing 1 is provided with a windshield device that can open and close the air outlet. When the air outlet of the fan faces the side air outlet, the windshield device on the side air outlet is opened, and the windshield device on the upper air outlet is closed. When the air outlet of the fan faces the upper air outlet, the windshield device on the upper air outlet is opened, and the windshield device on the side air outlet is closed, so that the air duct is complete, and the air outlet effect that can be achieved is the same as that of setting a single air outlet; the windshield device specifically includes a shutter and an air outlet controller, and the air outlet controller can control the opening and closing of the shutter to open or close the air outlet.

[0023] like Figure 3 As shown, the wind direction adjusting device specifically includes: a fan bracket 31, a connecting rod 32 and a power assembly. The wind direction adjusting device is arranged on the chassis 13 in the shell. The fan bracket is mounted with a fan 2. One end of the connecting rod 32 is connected to the fan bracket 31, and the other end of the connecting rod 32 is connected to the power assembly, so that the power assembly can drive the fan bracket 31 to rotate along a fulcrum or a rotation axis through the connecting rod 32, so that the fan 2 follows the rotation of the fan bracket 31 to adjust the direction of its air outlet.

[0024] In a specific embodiment, the side of the fan bracket 31 parallel to its rotation plane is L-shaped, the fan 2 is installed on one side of the L-shape, the connecting rod 32 is connected to the other side of the L-shape, the bending point of the L-shape is the connection point where the fan bracket is rotatably connected to the chassis in the shell, and the position of the L-shaped bending point is provided with a rotating shaft that is rotatably connected to the chassis 13 in the shell, so that the fan bracket 31 with an L-shaped side can be driven by the connecting rod to rotate 90 degrees, so that the air outlet of the fan can be adjusted. The power component specifically includes a cylinder 33 and a cylinder controller that controls the cylinder to change the specific state of the cylinder. The cylinder 33 is horizontally arranged with its telescopic movable part connected to the connecting rod. The specific state of the cylinder is that the movable part connected to the cylinder and the connecting rod extends to the far end or resets and retracts to the near end.

[0025] In the present invention, an air inlet is provided on the other side of the shell 1 opposite to the side air outlet 12 to form an air duct, and a filter 5 and a surface cooler 4 are provided in sequence on the air duct between the air inlet and the fan, so that the air can be filtered by the filter 5 at the air inlet and then heat exchanged through the surface cooler. At the same time, the overall structure is simplified to improve versatility.

[0026] In the present invention, the fan coil unit is specifically a cabinet type fan coil unit.

[0027] The present invention also provides an air conditioning system using the fan coil unit.

[0028] In specific use, the two air outlet controllers and the cylinder controller of the regulating cylinder form a closed-loop system. When the demand is for horizontal side air outlet, the air outlet controller of the side air outlet is turned on to control the shutter of the side air outlet to open, and at the same time, the air outlet controller of the upper air outlet is turned off to control the shutter of the upper air outlet to close, and the cylinder extends to the far end, and the unit maintains horizontal air outlet. Similarly, when the demand is for upper air outlet, the air outlet controller of the upper air outlet is turned on to control the shutter to open, the horizontal air outlet controller is turned off, the side air outlet is closed, and the cylinder retracts to the near end. Driven by the connecting rod, the fan blows the air outlet upward to correspond to the upper air outlet, so that the unit maintains the upper air outlet state. When the unit needs to be shut down, the fan stops running, the air outlet controllers of the upper air outlet and the side air outlet are kept in the closed state, both air outlets are closed, the cylinder is reset, and the unit is shut down.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
