[0039] Optionally, the first heat exchange device 4 is a micro-channel radiator composed of micro-channel cooling fins, which can be limited on the outside of the shell according to the shape of the indoor motor, so that the heat exchange process is more uniform and stable when the temperature of the indoor motor is exchanged by the first heat exchange device 4.

[0040] Figure 2 is a schematic diagram of a method for adjusting an air conditioner expansion valve provided by an embodiment of the present disclosure; in combination with Figure 2 As shown in the figure, optionally, the present disclosure provides a method for adjusting an air conditioner expansion valve, comprising:

[0041] S21, the air conditioner detects the current running mode of the air conditioner.

[0042] S22, the air conditioner acquires the first temperature collected by the first temperature sensor and the second temperature collected by the second temperature sensor.

[0043] S23, the air conditioner determines the adjustment strategy of the air conditioner expansion valve according to the current running mode, the first temperature and the second temperature.

[0044] S24, the air conditioner controls the air conditioner according to the adjustment strategy of the air conditioner expansion valve.

[0045] In this scheme, the air conditioner can determine the current running mode of the air conditioner through its associated mobile device or display panel. Here, the current running mode of the air conditioner can be a cooling mode, a heating mode or a dehumidifying mode, etc. In this way, the running state of the air conditioner can be accurately determined, providing accurate data basis for the determination of the flow direction of the air conditioner system refrigerant.

[0046] It can be understood that the air conditioner includes an indoor motor and an outdoor motor, in order to accurately determine the temperature of the indoor motor and the outdoor motor when running, a first temperature sensor for detecting temperature can be arranged at the indoor motor shell of the air conditioner, and a second temperature sensor for detecting temperature can be arranged at the outdoor motor shell. In this way, the user can determine the temperature of the indoor motor shell and the outdoor motor shell through the temperature values collected by the first temperature sensor and the second temperature sensor, providing accurate data basis for the determination of the adjustment strategy of the air conditioner expansion valve.

[0047] Further, after determining the current running mode, the first temperature and the second temperature, the air conditioner can accurately determine the adjustment strategy of the air conditioner expansion valve in combination with the current running mode, the first temperature and the second temperature. Specifically, the air conditioner can determine the on-off adjustment strategy of the air conditioner expansion valve according to the current running mode, determine the opening adjustment strategy of the air conditioner expansion valve according to the first temperature and the second temperature, and thus determine the on-off adjustment strategy and / or the opening adjustment strategy as the adjustment strategy of the air conditioner expansion valve. In this way, the accurate determination of the adjustment strategy of the air conditioner expansion valve can be realized in combination with the current running mode, the first temperature and the second temperature, so that the adjustment strategy of the expansion valve determined in this way is more in line with the flow characteristics of the refrigerant under different running modes. In this way, after determining the adjustment strategy of the expansion valve, the air conditioner can be controlled according to the adjustment strategy of the air conditioner expansion valve to control the refrigerant flow through the heat exchange device.

[0048] With the method for adjusting the expansion valve of the air conditioner provided in the embodiments of the present disclosure, the current operation mode of the air conditioner is detected, and the first temperature collected by the first temperature sensor and the second temperature collected by the second temperature sensor are obtained, so as to determine the adjustment strategy of the expansion valve of the air conditioner according to the current operation mode, the first temperature and the second temperature, and then control the air conditioner according to the adjustment strategy of the expansion valve of the air conditioner. With this scheme, the adjustment strategy of the expansion valve of the air conditioner can be accurately determined in combination with the current operation mode, the first temperature and the second temperature, so as to control the refrigerant flow through the heat exchange device in the case of controlling the air conditioner according to the adjustment strategy of the expansion valve of the air conditioner, effectively regulate the temperature during the operation of the motor, ensure the reliability and efficiency of the motor, and effectively recover the heat generated by the motor by using the refrigerant cooling method, thereby improving the efficiency of the air conditioner.

[0049] Figure 3 is a schematic diagram of a method for determining an adjustment strategy provided in the embodiments of the present disclosure; in combination with Figure 3 As shown in FIG. 8, optionally, S23, the air conditioner determines the adjustment strategy of the expansion valve of the air conditioner according to the current operation mode, the first temperature and the second temperature, including:

[0051] S32, the air conditioner determines the opening adjustment strategy of the expansion valve of the air conditioner according to the first temperature and the second temperature.

[0052] S33, the air conditioner determines the on-off adjustment strategy and / or the opening adjustment strategy as the adjustment strategy of the expansion valve of the air conditioner.

[0053] In this scheme, it can be understood that the on-off of the expansion valve can change the flow direction of the refrigerant in the refrigerant pipeline. Therefore, the air conditioner can determine the on-off adjustment strategy of the expansion valve of the air conditioner in combination with the current operation mode after obtaining the current operation mode. Specifically, in the case that the current operation mode is the cooling mode or the dehumidification mode, the on-off adjustment strategy of the expansion valve of the air conditioner is determined as controlling the first expansion valve and the third expansion valve to be opened and controlling the second expansion valve to be closed; in the case that the current operation mode is the heating mode, the on-off adjustment strategy of the expansion valve of the air conditioner is determined as controlling the second expansion valve and the third expansion valve to be opened and controlling the second expansion valve to be closed.

[0054] Further, the air conditioner can also determine the temperature conditions of the indoor motor housing and the outdoor motor housing according to the first temperature and the second temperature, and determine the opening adjustment strategy of the expansion valve of the air conditioner in combination with the temperature conditions of the indoor motor housing and the outdoor motor housing. In this way, the opening adjustment strategy of the expansion valve of the air conditioner can be accurately determined.

[0055] Further, the air conditioner determines the on-off regulation strategy and / or the opening degree regulation strategy as the regulation strategy of the air conditioner expansion valve after determining the on-off regulation strategy and the opening degree regulation strategy. In this way, the accurate determination of the air conditioner expansion valve regulation strategy can be realized in combination with the current operation mode, the first temperature and the second temperature, so that the expansion valve regulation strategy determined in this way is more in line with the flow characteristics of the refrigerant in the pipeline under different operation modes.

[0056] Optionally, in S31, the air conditioner determines an on-off regulation strategy of the air conditioner expansion valve according to the current operation mode, including:

In this way, the refrigerant can be facilitated to run through the first refrigerant circuit formed in the case where the air conditioner runs according to the on-off regulation strategy, so as to reduce the indoor environment temperature or reduce the humidity in the indoor environment. In the case where the current operation mode is the heating mode, the air conditioner determines that the on-off regulation strategy of the air conditioner expansion valve is to control the second expansion valve and the third expansion valve to be opened and control the second expansion valve to be closed, in combination with the refrigerant flow characteristics of the air conditioner in the heating mode. In this way, the refrigerant can be facilitated to run through the second refrigerant circuit formed in the case where the air conditioner runs according to the on-off regulation strategy, so as to effectively improve the indoor environment temperature.

As an example, if the suitable temperature range of the motor is 30-50, the first threshold value is determined as 30, and the second threshold value is determined as 50. The preset opening degree can be pre-stored in the air conditioner, and as an example, the preset opening degree is 20.

[0065] Further, the air conditioner can determine the opening degree adjustment strategy of the first expansion valve and the opening degree adjustment strategy of the third expansion valve as the opening degree adjustment strategies of the air conditioner expansion valve in the cooling mode or the dehumidifying mode after determining the opening degree adjustment strategy of the first expansion valve and the opening degree adjustment strategy of the third expansion valve. In this way, the temperature conditions of the indoor and outdoor motor housings can be determined in combination with the first temperature and the second temperature when the air conditioner operates in the cooling mode, thereby achieving accurate determination of the opening degree adjustment strategy of the air conditioner expansion valve.

The first threshold value and the second threshold value are determined by the suitable temperature range of the air conditioner motor, the suitable temperature range of the air conditioner motor refers to the best temperature operating range of the air conditioner motor, the first threshold value is the minimum value of the suitable temperature range, and the second threshold value is the maximum value of the suitable temperature range, and the suitable temperature range of the motor can be determined by the model of the motor. As an example, if the suitable temperature range of the motor is 30-50, the first threshold value is determined to be 30, and the second threshold value is determined to be 50. The preset opening can be pre-stored in the air conditioner, and as an example, the preset opening is 20.

[0072] Further, after the air conditioner determines the opening adjustment strategy of the second expansion valve and the opening adjustment strategy of the third expansion valve, the opening adjustment strategy of the second expansion valve and the opening adjustment strategy of the third expansion valve can be determined as the opening adjustment strategy of the air conditioner expansion valve in the heating mode. In this way, in the case that the air conditioner operates in the heating mode, the temperature conditions of the indoor and outdoor motor shells can be determined in combination with the first temperature and the second temperature, so as to accurately determine the opening adjustment strategy of the air conditioner expansion valve.

[0073] Optionally, S12, the air conditioner acquires a first temperature collected by a first temperature sensor and a second temperature collected by a second temperature sensor, comprising:

[0074] The air conditioner determines an initial control strategy of the air conditioner expansion valve matched with the current operation mode.

[0075] In the case that the air conditioner operates according to the initial control strategy, the air conditioner acquires a first temperature collected by a first temperature sensor and a second temperature collected by a second temperature sensor.

[0076] In the present solution, the air conditioner can pre-store the association relationship between different operation modes and the initial control strategy of the air conditioner expansion valve. As an example, if the current operation mode of the air conditioner is the cooling mode, the initial control strategy of the air conditioner expansion valve matched therewith is determined to be controlling the first expansion valve and the third expansion valve to start according to a preset step number. If the current operation mode of the air conditioner is the heating mode, the initial control strategy of the air conditioner expansion valve matched therewith is determined to be controlling the second expansion valve and the third expansion valve to start according to a preset step number. Here, the preset step number is preset by the user on the air conditioner. As an example, the preset step number is 200 steps. Further, in the case that the air conditioner operates according to the initial control strategy, the air conditioner acquires a first temperature collected by a first temperature sensor and a second temperature collected by a second temperature sensor. In this way, the acquisition time of the first temperature and the second temperature is accurately determined, and the accuracy of data acquisition is ensured.

[0078] S41, the air conditioner acquires a suitable temperature range of the air conditioner motor.

[0079] S42, in the case that the first temperature collected by the first temperature sensor and the second temperature collected by the second temperature sensor both fall into the suitable temperature range, the air conditioner controls the air conditioner to stop executing the adjustment strategy of the air conditioner expansion valve.

[0080] In the scheme, the air conditioner can obtain a suitable temperature range of the air conditioner motor. Here, the suitable temperature range of the air conditioner motor refers to the optimal temperature operating range of the air conditioner motor, which is usually determined by the model of the motor. As an example, the air conditioner can pre-store the suitable temperature ranges of air conditioner motors of different models, and after the air conditioner determines the motor model, the suitable temperature range is accurately determined. Further, in the case where the first temperature collected by the first temperature sensor and the second temperature collected by the second temperature sensor both fall within the suitable temperature range, the air conditioner controls the air conditioner to stop executing the adjustment strategy of the air conditioner expansion valve. In this way, in the case where the temperature conditions of the indoor motor and the outdoor motor are consistent with the suitable temperature range, the air conditioner is controlled to stop executing the adjustment strategy of the air conditioner expansion valve. By accurately determining the end time, the user's demand for energy-saving control of the air conditioner is effectively met.
