However, when the outdoor unit of the air conditioner is running for a long time in a high temperature environment, the heat dissipation capacity of the above heat dissipation structure for the compressor and the control board is limited, affecting the service life of the air conditioner.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0022] Please refer to the following Figure 1 and Figure 2 An air conditioning system according to an embodiment of the present invention is described.

[0023] like Figure 1 and Figure 2 As shown, the air-conditioning system of the embodiment of the utility model includes: an indoor unit 1, an outdoor unit 2 and a cold air duct 3, the indoor unit 1 includes an inner casing 11 and a cold air module 12, the cold air module 12 is arranged in the inner casing 11, the outdoor unit 2 includes an outer casing 21, the air inlet end of the cold air duct 3 is connected to the cold air module 12, and the air outlet end of the cold air duct 3 is connected to the outer casing 21, and the cold air module 12 is used to guide the indoor cold air in the indoor environment 10 into the cold air duct 3.

[0024] According to the air conditioning system of the embodiment of the utility model, since the air inlet end of the cold air pipe 3 is connected to the cold air module 12, the air outlet end of the cold air pipe 3 is passed into the outer casing 21. When the air conditioning system is in cooling mode, the cold air module 12 can guide the indoor cold air into the outer casing 21 through the cold air pipe 3 to effectively dissipate the heat of the components in the outdoor unit 2 and extend the service life of the outdoor unit 2.

[0025] In addition, the air-conditioning system of the embodiment of the utility model installs the cold air module 12 on the inner casing 11. Compared with the solution of installing the cold air module 12 on the outer casing 21, on the one hand, it can avoid exposing the cold air module 12 to the outdoor environment, which is beneficial to ensuring the reliability of the operation of the cold air module 12; on the other hand, it can reduce the space occupied by the outer casing 21, which is beneficial to reducing the external dimensions of the outer casing 21.

[0026] It should be noted that if Figure 1 As shown, the air-conditioning system also includes a refrigerant pipe 4, and the indoor unit 1 also includes an evaporator. The evaporator is arranged in the inner shell 11. One end of the refrigerant pipe 4 is connected to the evaporator, and the other end of the refrigerant pipe 4 is connected to the compressor 25 to realize heat exchange between the outdoor unit 2 and the indoor unit 1.

[0027] Optionally, the cold air module 12 includes a driving member and a fan, the driving member is arranged in the inner housing 11 and is connected to the fan in a driving manner, and the blowing side of the fan is opposite to the air inlet end of the cold air pipe 3. For example, the driving member is a motor, the motor is installed in the inner housing 11, and the motor drives the fan to rotate. Since the blowing side of the fan is opposite to the air inlet end of the cold air pipe 3, the cold air in the room can be guided to the cold air pipe 3. The air conditioning system of the embodiment of the utility model can facilitate the integration of the cold air module 12 in the inner housing 11 by setting the cold air module 12 as the above structure, and the difficulty of processing and manufacturing is relatively low.

[0028] In one example, the air conditioning system further includes a temperature sensor (not shown), which is disposed in the outer casing 21 and electrically connected to the driving member, and the temperature sensor is used to detect the temperature in the outer casing 21, and the driving member can adjust the wind speed of the fan according to the temperature signal of the temperature sensor. It can be understood that when the temperature sensor detects that the temperature in the outer casing 21 exceeds a preset value, the driving member can be controlled to turn on, and the wind speed of the fan can be controlled according to the temperature gradient in the outer casing 21. Correspondingly, when the temperature sensor detects that the temperature in the outdoor unit 2 is lower than a preset value, the driving member can be turned off or the wind speed of the fan can be reduced. In this way, the air conditioning system can meet different application scenarios and have low energy consumption.

[0029] like Figure 1 As shown, the outer casing 21 has a fan cavity 211 and a compressor cavity 212, the outdoor unit 2 includes a fan 24, a compressor 25 and an electric control module 22, the fan 24 is arranged in the fan cavity 211, the compressor 25 and the electric control module 22 are arranged in the compressor cavity 212, and the air outlet end of the cold air pipe 3 is connected with the compressor cavity 212. It can be understood that the outdoor unit 2 also includes a middle partition 23, and the middle partition 23 divides the cavity of the outer casing 21 into the fan cavity 211 and the compressor cavity 212. Since the air outlet end of the cold air pipe 3 is connected with the compressor cavity 212, the cold air entering the outer casing 21 can directly cool the compressor 25 and the electric control module 22 in the compressor cavity 212, which is conducive to improving the cooling effect of the compressor 25 and the electric control module 22.

[0030] Optionally, the air outlet may be one or more. In the example of the present application, the air outlet is multiple.

[0031] Specifically, the cold air pipe 3 has a plurality of branch pipes (not shown), each of which is provided with an air outlet, a part of which is opened toward the direction of the compressor 25, and another part of which is opened toward the direction of the electronic control module 22. In other words, a part of the branch pipes can cool the compressor 25 alone, and another part of the branch pipes can cool the electronic control module 22 alone, thereby further improving the cooling effect of the compressor 25 and the electronic control module 22, avoiding the waste of cooling capacity, and being conducive to reducing the energy consumption of the air conditioning system.

[0032] Alternatively, if Figure 2 As shown, the outer housing 21 is provided with a plurality of heat dissipation holes (not shown), which are connected to the compressor cavity 212. The electric control module 22 includes an electric control box 221 and a controller, which is arranged in the electric control box 221. The electric control box 221 is provided with a plurality of ventilation holes (not shown), which are connected to the fan cavity 211 and the compressor cavity 212. It can be understood that when the fan 24 rotates, the fan cavity 211 is in a negative pressure state, and the pressure of the compressor cavity 212 is higher. Figure 1 As shown by the arrows in , the convection air enters the compressor cavity 212 from the right side plate (i.e., the heat dissipation hole) of the outer casing 21, and then enters the fan cavity 211 through the ventilation holes on the electric control box 221. The convection air can play a certain role in cooling the compressor 25 and the controller.

[0033] Therefore, the air-conditioning system of the embodiment of the utility model can not only cool the compressor 25 and the controller by air convection through the rotation of the fan 24, but also cool the compressor 25 and the controller by blowing cold air through the cold air duct 3, which is beneficial to improving the heat dissipation effect of the outdoor unit 2 of the air-conditioning system and ensuring the service life of the outdoor unit 2.
