Each of the indoor unit and the outdoor unit further includes a plurality of sensors 20 for detecting an operation state of the air conditioning unit, and the sensors may be, for example, a temperature/humidity sensor, a pressure sensor, and the like.

The operation mechanism of the controller 19 of the indoor unit will be described in detail.
Fig. 2 is a block schematic diagram of a controller shown according to an embodiment of the present disclosure, the controller 19 comprising: an acquisition module 191, a determination module 192, and a control module 193.
The obtaining module 191 is used for obtaining air conditioner setting parameters and state data of the air conditioning unit.
The air conditioner setting parameters are generally set by a user according to actual requirements, and may include but are not limited to setting temperature, setting humidity, air conditioner operation mode, air outlet mode and the like. The status data includes: operating parameters of each actuator, such as an operating frequency of the compressor 15, an opening degree of the electronic expansion valve 17, a rotation speed of the inner fan 11, a fan gear of the inner fan 11, a rotation speed of the outer fan 16, a fan gear of the outer fan 16, and the like; and state parameters detected by each sensor in the air conditioning unit, such as the environment temperature and humidity of the environment where the indoor unit is located, the refrigeration evaporation temperature, the heating condensation temperature, the air outlet temperature and humidity, the air inlet temperature and humidity, and the like.
The determination module 192 is configured to determine a target operating parameter for each actuator, the target operating parameter being determined based on the state data and a predefined operational decision rule.
The operation decision rule is used for determining an operation scheme of the air conditioning unit according to the state data of the air conditioning unit, and the operation scheme comprises target operation parameters of the actuator.
The operation decision rule may comprise a plurality of decision sub-rules, each for determining an operating parameter of an actuator. Each operational decision rule defines the state parameters required for determining the operating parameters of the corresponding actuator, which may be determined from practical experience. For example, if the decision rule a is used to determine the operating frequency (target operating parameter) of the compressor 15, assuming that the operating frequency of the compressor 15 is related to the set temperature and the outlet temperature, the operation relationship between the set temperature, the outlet temperature and the operating frequency needs to be defined in the operation decision rule a, and when the operating parameter of the compressor 15 is determined, the numerical value of the set temperature and the numerical value of the outlet temperature are assigned to the operation decision rule a to determine the operating frequency of the compressor 15; if the operation decision rule b is used for determining the opening degree (target operation parameter) of the electronic expansion valve 17, assuming that the opening degree of the electronic expansion valve 17 is related to the set temperature, the air outlet temperature and the refrigeration evaporation temperature, the operation relation between the set temperature, the air outlet temperature and the refrigeration evaporation temperature and the opening degree needs to be defined in the operation decision rule b, and when the opening degree of the electronic expansion valve 17 is determined, the numerical value of the set temperature, the numerical value of the air outlet temperature and the numerical value of the refrigeration evaporation temperature are assigned to the operation decision rule b to determine the opening degree of the electronic expansion valve 17.
If the operation decision rule includes a plurality of decision sub-rules, the determining module 192 may call the plurality of decision sub-rules in parallel to adjust the temperature quickly when determining the target operation parameter of each actuator.
The operation decision rule can simultaneously output target operation parameters of a plurality of actuators according to the state data. The operation decision rule can be obtained by training a machine learning model or a neural network. Taking an operation decision rule obtained by training a neural network as an example, obtaining operation parameters of each actuator in normal operation under different state data, taking the state data and the corresponding operation parameters as training samples to train the neural network, and taking the trained neural network as the operation decision rule to determine the operation parameters of the actuator.
Based on the operation decision rule, a plurality of sets of operation schemes may be determined, the scheme with the minimum total power consumption of operation of each operator in the plurality of sets of operation schemes may be determined as the final operation scheme, and the target operation parameters of each actuator in the operation scheme with the minimum total power consumption are sent to the control module 193.
The control module 193 is configured to adjust the operating parameters of each actuator to target operating parameters.
Specifically, the control module 193 converts the target operating parameters of each actuator into control instructions and sends the control instructions to the corresponding actuator, so that the operating parameters of each actuator are adjusted to the target operating parameters, and thus the indoor environmental parameters, such as temperature and humidity, can be quickly adjusted within the respective set parameter ranges with minimum power consumption.
In the present disclosure, the operation parameters of each actuator may be adjusted, but not limited to, by using fuzzy control or PID (a closed loop control algorithm) control, and the target operation parameters are converted into control commands based on the control algorithm and are respectively sent to each actuator in the outdoor unit and each actuator in the indoor unit.
The following takes the indoor temperature higher than the set temperature as an example, and further explains the control mechanism of the air conditioning unit: assuming that the current indoor temperature is T, the set temperature is T ', the outlet temperature is T, the current operating frequency of the compressor 15 is F, the opening degree of the electronic expansion valve 17 is P, the rotation speed of the outer fan 16 is N1, and the rotation speed of the inner fan 11 is N2, the state data is input into the operation decision rule to obtain the target operating frequency of the compressor 15 as F ', the opening degree of the electronic expansion valve 17 as P ', the rotation speed of the outer fan 16 as N1 ', and the rotation speed of the inner fan 11 as N2 '. In order to lower the indoor temperature to T ', the controller 19 continuously performs PID control on the compressor 15, the electronic expansion valve 17, the outer fan 16, and the inner fan 11 such that the operating frequency of the compressor 15 is increased from F to F ', the opening P of the electronic expansion valve 17 is adjusted to P ', the rotation speed of the outer fan 16 is adjusted from N1 to N1 ', and the rotation speed of the inner fan 11 is adjusted from N2 to N2 '.
In the embodiment of the disclosure, the operation decision rule is deployed in the indoor unit, and the indoor unit executes the decision operation, so that compared with the operation decision rule deployed in the outdoor unit, the execution environment of the operation decision rule is mild, the service life of components executing the operation decision rule can be prolonged, the normal operation of the components is ensured, and the accuracy of operation parameters is further ensured; and moreover, the operation decision rule is deployed in the indoor unit, so that all state data of the air conditioning unit can be acquired, and the target operation parameters of each actuator can be determined according to the state data, so that the actuators can be controlled in a linkage manner, and the actuators are not controlled independently, so that the accurate control and the energy-saving operation of the air conditioning unit during operation are realized.

The PFC circuit 195 adjusts the power factor of the dc power supply to the compressor 15 based on the control of the controller 19, for example, to increase and stabilize the voltage of the dc power supply at 380V, so that the input current follows the input voltage, and the power factor is ensured to be above 0.9.
In one embodiment, referring to fig. 3, an expansion valve signal circuit is disposed on the controller 19, the expansion valve signal circuit is electrically connected to the obtaining module 191 and the electronic expansion valve 17, and the expansion valve signal circuit is configured to collect the operation parameters of the electronic expansion valve 17 and send the operation parameters of the electronic expansion valve 17 to the obtaining module 191.

Of course, the obtaining module 191 further obtains the operating parameters of each actuator in the indoor unit, for example, the obtaining module obtains the operating parameters of the inner fan collected by the fan signal circuit disposed in the controller, and summarizes the obtained operating parameters of all the actuators and the state parameters detected by each sensor as state data to be sent to the determining module 192, so that the determining module 192 determines the target operating parameters of each actuator, and then the control module 193 adjusts the operating parameters of each actuator to the target operating parameters. The specific implementation processes of the determining module 192 and the control module 193 are described in the above embodiments, and are not described herein again.
In the related art, in order to ensure the normal operation of the air conditioning unit, the operation parameter range of each actuator is set as a decision parameter in an operation decision rule, so that each actuator operates in the operation parameter range as much as possible. When the operation parameters exceed the operation parameter range, the air conditioning unit gives an alarm. If the operating parameter exceeds the operating parameter range and is not due to the hardware failure engine, the alarm can be eliminated by updating the operating parameter range in the scene. In order to facilitate the update of the operation parameter range, a communication module may be deployed in the controller 19, and the communication module may be implemented by, but not limited to, a bluetooth module, a Wi-Fi module, or other wireless communication modules, and the controller 19 may establish a communication connection with an external device through the communication module, and obtain a decision parameter sent by the external device, so as to update the operation decision rule according to the decision parameter.
