[0019] According to an embodiment of the present invention, an embodiment of an air injection control method of an air-conditioning system is provided. It should be noted that the steps shown in the flow charts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0020] figure 1 is a flow chart of an air injection control method for an air conditioning system according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0021] Step S102, obtaining the discharge temperature of the compressor and the adjustment parameters of the electronic expansion valve in real time.

[0022] Specifically, in the above steps, the above adjustment parameters may be parameters used for compensatio

[0069] According to an embodiment of the present invention, an embodiment of an air injection control device for an air conditioning system is provided, image 3 It is a structural schematic diagram of an air injection control system of an air conditioning system according to an embodiment of the present invention, such as image 3 As shown, the system includes:

[0070] The acquisition device 30 is used to acquire the discharge temperature of the compressor and the adjustment parameters of the electronic expansion valve in real time.

[0071] The controller 32 is connected with the acquisition device, and is used for controlling the opening degree of the electronic expansion valve according to the discharge temperature of the compressor and the adjustment parameters of the electronic expansion valve.

[0072] In an optional embodiment, since the control target is the discharge temperature of the compressor, the current detected discharge temperature of the compressor can be com

[0094] According to an embodiment of the present invention, an air conditioner is provided, and the air conditioner includes any air injection control system of the air conditioning system in Embodiment 2.

[0095] In an optional embodiment, since the control target is the discharge temperature of the compressor, the air conditioner can compare the detected current discharge temperature of the compressor with the preset discharge temperature, and then adjust the parameter The preset range controls the opening of the electronic expansion valve.

[0096]The air conditioner proposed in the above embodiments obtains the discharge temperature of the compressor and the adjustment parameters of the electronic expansion valve in real time, and controls the opening of the electronic expansion valve according to the discharge temperature of the compressor and the adjustment parameters of the electronic expansion valve. The above solution uses the discharge temperature of the compressor and
