[0018] Reference Figure 1 An air conditioning system capable of cooling a driving plate includes a compressor 10, a four-way valve 20, an indoor heat exchanger 30, an outdoor heat exchanger 40, a gas-liquid separator 50, and a driving plate cooling pipeline 60. The driving plate cooling pipeline 60 connects the output end of the outdoor heat exchanger 40 with the input end of the gas-liquid separator 50. The driving plate cooling pipeline 60 can heat exchange a part of the low-temperature refrigerant output by the outdoor heat exchanger 40 with the compressor driving plate.

[0019] It is worth noting that in an air-conditioning system of the utility model that can cool the drive plate, the pipeline connection in the cooling mode is: the output end of the compressor 10 is connected to the outdoor heat exchanger 40 through the four-way valve 20, the output end of the outdoor heat exchanger 40 is connected to the indoor heat exchanger 30, and the output end of the indoor heat exchanger 30 is connected to the four-way valve 20 and then connected to the gas-liquid separator 50 through another pipeline output end of the four-way valve 20, and the gas-liquid separator 50 is connected to the input end of the compressor 10.

[0020] It is understandable that a portion of the low-temperature refrigerant output by the outdoor heat exchanger 40 is exchanged with the compressor drive plate through the drive plate cooling pipeline 60 to cool the compressor drive plate, thereby reducing the temperature rise of the compressor drive plate during high-temperature refrigeration and improving the reliability of the air-conditioning system. In addition, the drive plate cooling pipeline 60 connects the output end of the outdoor heat exchanger 40 with the input end of the gas-liquid separator 50, and the refrigerant after cooling the compressor drive plate directly flows to the gas-liquid separator 50, which will not affect the temperature of the refrigerant flowing to the indoor heat exchanger 30, thereby ensuring that the air-conditioning refrigeration effect will not be affected by the drive plate cooling refrigerant.

[0021] Reference Figure 1 The drive plate cooling pipeline 60 includes a first input pipe 61, a first solenoid valve 62, a drive plate heat dissipation module 63 and a first output pipe 64. One end of the first input pipe 61 is connected to the output end of the outdoor heat exchanger 40, and the other end is connected to the input end of the drive plate heat dissipation module 63. The first solenoid valve 62 is arranged on the first input pipe 61. One end of the first output pipe 64 is connected to the output end of the drive plate heat dissipation module 63, and the other end is connected to the input end of the gas-liquid separator 50. The drive plate heat dissipation module 63 is located on one side of the compressor drive plate.

[0022] In some embodiments of the present invention, a portion of the low-temperature refrigerant output by the outdoor heat exchanger 40 can be directly input into the drive plate heat dissipation module 63 through the first input pipe 61 for heat exchange and cooling, and the opening and closing of the first input pipe 61 can be controlled by the first solenoid valve 62.

[0023] Reference Figure 1 The driving plate cooling pipeline 60 further includes a second input pipe 65. One end of the second input pipe 65 is connected to the output end of the outdoor heat exchanger 40, and the other end is connected to the input end of the driving plate heat dissipation module 63. A second electronic expansion valve 66 is provided on the second input pipe 65.

[0024] In other embodiments of the present invention, the amount of refrigerant input to the driver board heat dissipation module 63 may be further increased through the second input pipe 65 , and the refrigerant input amount of the second input pipe 65 may be regulated by the second electronic expansion valve 66 .

[0025] Reference Figure 1 , an air conditioning system capable of cooling the driving plate further comprises a pipeline control system 70. The pipeline control system 70 can control the switch of the air conditioning system and the switch of the driving plate cooling pipeline 60.

[0026] Reference Figure 1The pipeline control system 70 includes a first electronic expansion valve 71, an outdoor air inlet temperature sensing package 72, an indoor environment temperature sensing package 73, a driving heat dissipation module humidity sensor 74, a driving heat dissipation module inlet pipe temperature sensing package 75, and a driving heat dissipation module environment temperature sensing package 76. The first electronic expansion valve 71 is arranged between the outdoor heat exchanger 40 and the indoor heat exchanger 30. The outdoor air inlet temperature sensing package 72 is arranged on the outdoor heat exchanger 40. The indoor environment temperature sensing package 73 is arranged on the indoor heat exchanger 30. The driving heat dissipation module humidity sensor 74, the driving heat dissipation module inlet pipe temperature sensing package 75, and the driving heat dissipation module environment temperature sensing package 76 are all arranged on the driving board heat dissipation module 63.

[0027] It is worth noting that in the embodiment of the utility model, the outdoor air inlet temperature sensing package 72 can detect the outdoor fan air inlet temperature. The indoor ambient temperature sensing package 73 can detect the indoor ambient temperature. The driving heat dissipation module humidity sensor 74 can detect the relative humidity of the environment where the driving plate heat dissipation module 63 is located. The driving heat dissipation module inlet pipe temperature sensing package 75 can detect the inlet pipe temperature of the driving plate heat dissipation module 63. The driving heat dissipation module ambient temperature sensing package 76 can detect the ambient temperature of the driving plate heat dissipation module 63. The dew point temperature of the driving plate heat dissipation module 63 can be converted according to the relative humidity of the environment where the driving plate heat dissipation module 63 is located and the ambient temperature of the driving plate heat dissipation module 63 detected by the driving heat dissipation module ambient temperature sensing package 76. Please refer to the following table for the conversion method:

[0030] According to the dew point temperature of the drive plate heat dissipation module 63, the opening of the second electronic expansion valve 66 can be adjusted to adjust the amount of refrigerant entering the drive plate heat dissipation module 63 to balance the refrigerant for refrigeration and cooling of the compressor drive plate.
