[0037] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] The following describes in detail the control method, system, air conditioner, device and medium of the air conditioner according to the embodiments of the present application in conjunction with the accompanying drawings.

[0040] Before describing the control method of the air conditioner in the embodiment of the present invention, the air conditioner is first explained. The air conditioner, that is, the air conditioning system, usually includes two parts: an indoor unit and an outdoor unit. Of course, it can also be an integrated indoor and outdoor unit air conditioner, that is, the indoor unit and the outdoor unit are integrated. The air conditioner includes a compressor, an evaporator, a condenser, a throttling component, etc., and the compressor, evaporator, condenser, throttling component, etc. constitute the refrigeration system of the air conditioner. Of course, the air conditioner in the embodiment of the present application can also refer to a heat pump system that can both cool and heat. The air conditioner usually also includes a four-way valve to control the direction of the condenser, so that the heat pump system can both heat and cool.

[0041] Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present application. Figure 1 As shown, a method for controlling an air conditioner according to an embodiment of the present application includes the following steps:

[0042] S101: Obtain the operating status of the air conditioner.

[0043] In one embodiment of the present invention, the operating state of the air conditioner includes an energy-reduction response state and a non-energy-reduction response state, wherein the non-energy-reduction response state refers to an operating state other than the energy-reduction response state.

[0044] The energy consumption reduction response state can be achieved by receiving an energy consumption response command sent from the outside, so that the air conditioner's operating state enters the energy consumption reduction response state. For example: according to the increasing demand for peak-shifting response of the power grid, an energy consumption response command issued by the power grid will be received during a certain period of time.

[0045] In a specific example, the air conditioner may include a communication module for communicating with the outside, and receive the energy consumption response command issued by the power grid through the communication module. The communication module generally refers to a network interconnection device that can access the Internet.

[0046] When the air conditioner receives the energy consumption response command and enters the energy consumption reduction response state, it can be obtained that the operating state of the air conditioner is in the energy consumption reduction response state. Otherwise, it can be obtained that the air conditioner is in the non-energy consumption reduction response state.

[0047] S102: When the operation state of the air conditioner is in the energy consumption reduction response state, it is determined whether the output limit of the outdoor unit reaches the energy consumption reduction target of the air conditioner.

[0048] As the demand for power grid peak response increases, it is usually necessary to ensure that the air conditioner can achieve sufficient peak response effect. At present, the conventional control is to directly limit the output of the air conditioner's outdoor unit. However, in some actual energy reduction processes, there are usually indicators that need to be achieved by force, such as: the energy reduction target value needs to be achieved, that is, the actual power of the air conditioner needs to be reduced to a certain extent so that the overall energy consumption of the air conditioner is reduced to the energy reduction target value.

[0049] However, in some scenarios, it is difficult to achieve this indicator for the control of the outdoor unit. For example, when the user has strict requirements for the indoor environment, the energy consumption of the indoor unit of the air conditioner is relatively large. Therefore, in an embodiment of the present invention, when the operating state of the air conditioner is in the energy reduction response state, the outdoor unit is already in the energy reduction control. At this time, it is necessary to determine whether the output limit of the outdoor unit meets the energy reduction target of the air conditioner.

[0050] In one embodiment of the present invention, determining whether the output limit of the outdoor unit reaches the energy consumption reduction target of the air conditioner includes: comparing the real-time power of the air conditioner with a first preset power, wherein the first preset power is determined according to the energy consumption reduction target value; if the real-time power is not less than the first preset power, determining that the output limit of the outdoor unit does not reach the energy consumption reduction target of the air conditioner.

[0051] That is to say, when the operating state of the air conditioner is in the energy consumption reduction response state, the outdoor unit of the air conditioner will take corresponding energy consumption reduction control, that is: limit the output of the outdoor unit, so that the overall real-time power of the air conditioner will decrease. After the overall real-time power of the air conditioner decreases, it is determined whether the real-time power of the air conditioner at this time is less than a preset threshold (that is, the first preset power). If the real-time power at this time is still greater than or equal to the preset threshold, it means that when the output of the outdoor unit is limited, the overall real-time power of the air conditioner cannot meet the energy consumption reduction requirements. In other words, after the output of the outdoor unit is limited, the overall real-time power of the air conditioner still fails to reach the energy consumption reduction target of the air conditioner.

[0052] In the above example, the real-time power is recorded as P, and the first preset power is recorded as P_A, that is, when the operating state of the air conditioner is in the energy-saving response state, if P≥P_A, it is considered that even if the output of the outdoor unit is limited, the overall real-time power of the air conditioner cannot meet the energy-saving requirements.

[0053] The first preset power P_A is determined according to the energy consumption reduction target value. For example, if the energy consumption reduction target value is 40% of the rated power of the whole machine under the current working condition of the air conditioner, then P_A can be set to about 40% of the rated power of the whole machine under the current working condition of the air conditioner. Generally speaking, P_A can be set to a value slightly smaller than the energy consumption reduction target value.

[0054] It should be noted that the energy consumption reduction target value is a value smaller than the rated power of the whole machine under the current operating condition of the air conditioner. For example, the energy consumption reduction target value is 10% to 99% of the rated power of the whole machine under the current operating condition. Therefore, the value range of the first preset power P_A can also be 10% to 99% of the rated power of the whole machine under the current operating condition of the air conditioner.

[0055] In another example, in the process of judging whether the output limit of the outdoor unit has reached the energy reduction target of the air conditioner, other operating parameters of the air conditioner can also be introduced to assist in judging whether the output limit for the outdoor unit has reached the limit, that is, judging whether the energy reduction target of the air conditioner can be achieved when the output limit for the outdoor unit has reached the limit. Specifically, judging whether the output limit of the outdoor unit has reached the energy reduction target of the air conditioner includes: comparing the real-time power of the air conditioner with the second preset power, wherein the second preset power is determined according to the energy reduction target value; if the real-time power is not less than the second preset power, further judging whether the outdoor unit has reached the energy reduction limit according to the operating parameters of the outdoor unit; if the outdoor unit has reached the energy reduction limit, determining that the output limit of the outdoor unit has not reached the energy reduction target of the air conditioner.

[0056] In this example, the second preset power can be set to be the same as the first preset power in the above embodiment. That is, the second preset power can also be expressed as P_A. In this example, the real-time power of the air conditioner is also recorded as P. Therefore, in this embodiment, when the operating state of the air conditioner is in the energy-saving response state and P≥P_A, although it means that the output limit of the outdoor unit at this time cannot achieve the energy-saving target of the air conditioner, it will be further judged whether the outdoor unit has reached the energy-saving limit according to the operating parameters of the outdoor unit. For example, the operating parameters of the outdoor unit are already very small, that is, the operating power of the outdoor unit can no longer be reduced. At this time, it means that the energy-saving control of the outdoor unit has reached the energy-saving limit. If the energy-saving control of the outdoor unit has reached the energy-saving limit, after the energy-saving control of the outdoor unit reaches the energy-saving limit, it is judged whether the air conditioner has reached the energy-saving target according to the real-time power.

[0057] In the above example, the operating parameters of the outdoor unit include but are not limited to the compressor frequency of the outdoor unit, the wind speed of the outdoor unit, the overall output power of the outdoor unit, etc. For example, after the wind speed of the outdoor unit has been adjusted to the lowest level, it is determined whether the air conditioner can achieve the energy reduction target based on the real-time power.

[0058] In the specific example, the operating parameters of the outdoor unit take the compressor frequency as an example. When the operating state of the air conditioner is in the energy consumption reduction response state and P≥P_A, it is determined whether the compressor frequency is less than or equal to a preset frequency. If it is less than or equal to the preset frequency, it is considered that the output limit for the outdoor unit has reached the limit.

[0059] The preset frequency is recorded as Hz_A, and the preset frequency Hz_A can be selected as 1% to 99% of the current compressor operating frequency range. The operating parameters of the outdoor unit, such as the compressor frequency, are used to control the hysteresis, that is, to prevent the influence of the change of the indoor unit's wind speed on the comfort index. For example, when the wind speed of the indoor unit is forced to be reduced, the comfort index will change. If the compressor frequency of the outdoor unit is already very low, it may trigger the situation that the comfort does not meet the comfort index requirements and the air conditioner exits the energy reduction response state. In this embodiment, by introducing the outdoor unit's operating parameters such as the compressor frequency judgment, the influence of the indoor unit's wind speed change and frequency coupling on the whole machine power consumption can be reduced. That is to say, even if the compressor frequency is very small, such as the compressor frequency ≤ Hz_A, even if the indoor unit's wind speed and other parameters are reduced, the air conditioner will not exit the energy reduction response state. It is avoided that the air conditioner no longer responds to the energy consumption response command.

[0060] S103: If the energy consumption reduction target of the air conditioner is not reached, the indoor unit is controlled to reduce energy consumption.

[0061] After it is determined in step S102 that the output restriction on the outdoor unit fails to achieve the energy consumption reduction target of the air conditioner, in an embodiment of the present invention, energy consumption reduction control is performed on the indoor unit, wherein the energy consumption reduction control on the indoor unit includes but is not limited to reducing or shutting down some auxiliary devices, reducing the air speed of the indoor unit, etc., and examples of auxiliary devices include but are not limited to electric auxiliary heating. In the energy consumption reduction control of the indoor unit, (1) step-by-step control and (2) forced control can be adopted, wherein the step-by-step control can include gradually lowering the air speed of the indoor unit, gradually reducing the electric auxiliary heating, etc., and the forced control can include directly adjusting the air speed of the indoor unit to the minimum, directly shutting down the electric auxiliary heating, etc.

[0062] Specifically, the energy consumption reduction control of the indoor unit includes: when the air conditioner is in heating mode, turning off the electric auxiliary heating output of the indoor unit, and after turning off the electric auxiliary heating output of the indoor unit, judging whether the energy consumption reduction target of the air conditioner is achieved, if the energy consumption reduction target of the air conditioner is not achieved, directly adjusting the wind speed of the indoor unit to the lowest wind speed, or gradually reducing the electric auxiliary heating output of the indoor unit until it is turned off, and in the process of gradually reducing the electric auxiliary heating output of the indoor unit until it is turned off, judging whether the energy consumption reduction target of the air conditioner is achieved, if the energy consumption reduction target of the air conditioner is not achieved, gradually reducing the wind speed of the indoor unit until the energy consumption reduction target of the air conditioner is achieved or the wind speed of the indoor unit is adjusted to the lowest wind speed; when the air conditioner is not in heating mode, directly adjusting the wind speed of the indoor unit to the lowest wind speed, or gradually reducing the wind speed of the indoor unit until the energy consumption reduction target of the air conditioner is achieved or the wind speed of the indoor unit is adjusted to the lowest wind speed.

[0063] That is, the energy consumption reduction control method of the indoor unit is:

[0064] Method (1): Control step by step, reduce the electric auxiliary heating output of the indoor unit until it is turned off, and then reduce the indoor unit fan speed step by step until it reaches the lowest fan speed. During this process, it is determined in real time whether the real-time power of the air conditioner reaches the energy consumption reduction target value. If so, maintain the current operating state. If not, continue to reduce step by step until all controls are completed.

[0065] Method (2): Forced control, directly turn off the electric auxiliary heating, and then directly limit the wind speed of the indoor unit to the lowest wind speed. In this process, it is judged in real time whether the real-time power of the air conditioner reaches the energy consumption reduction target value. If so, the current operating state is maintained.

[0066] It should be noted that if the air conditioner does not have electric auxiliary heating, the control of the electric auxiliary heating is skipped and the wind speed of the indoor unit is directly controlled.

[0067] According to the control method of the air conditioner in the embodiment of the present invention, when the operating state of the air conditioner is in the energy consumption reduction response state, the output of the outdoor unit is limited. In this process, it is judged whether the output limitation of the outdoor unit can enable the air conditioner to reach the energy consumption reduction target according to the real-time power of the air conditioner. If the air conditioner cannot reach the energy consumption reduction target, when the energy consumption reduction control effect is insufficient, the indoor unit can be involved in the energy consumption reduction control, thereby effectively reducing the real-time power of the air conditioner, so that the air conditioner reaches or is as close as possible to the energy consumption reduction target, and better meets the energy consumption response requirements.

[0068] In one embodiment of the present invention, the control method of the air conditioner, after obtaining the operating status of the air conditioner, further includes: judging whether at least one of the following conditions is met: the operating status of the air conditioner is not in the energy reduction response state, and the real-time power of the air conditioner is less than a third preset power; when at least one of the conditions is met, further judging whether the indoor unit is in the energy reduction control state; if the indoor unit is in the energy reduction control state, restoring the indoor unit to default control.

[0069] That is, if the air conditioner is not in the energy-saving response state, or the real-time power P of the air conditioner is less than a preset threshold (i.e., the third preset power), the preset threshold is recorded as P_B, if the air conditioner is in the energy-saving control state, for example, the wind speed is not in accordance with the user's requirements, but is at the lowest level, then the indoor unit is restored to the default control, for example, the high wind speed set by the user is restored. In this way, the user's needs can be better met and the user experience of the air conditioner can be improved. Generally speaking, P_B≤P_A, and the value of P_B ​​can be 1% to 99% of the rated power of the air conditioner under the current working conditions.

[0070] On the basis of this example, in another example of the present invention, the above conditions may also include: the operating parameters of the outdoor unit are greater than the predetermined parameter values. Among them, the operating parameters of the outdoor unit are as described in the above embodiment and will not be repeated here. Taking the compressor frequency as an example, if the air conditioner is not in an energy-saving response state, or the real-time power of the air conditioner P<P_B, or the compressor frequency is greater than a predetermined frequency, the predetermined frequency is recorded as Hz_B, and Hz_B can be 1% to 99% of the current compressor operating frequency range. In general, Hz_A≤Hz_B. In this way, the air conditioner can better meet the user's usage needs.

[0071] Figure 2 FIG. 1 is a structural block diagram of an air conditioning control system according to an embodiment of the present application. Figure 2 As shown, the air conditioning control system according to an embodiment of the present application includes: an acquisition module 210, a judgment module 220 and a control module 230. Among them:

[0072] The acquisition module 210 is used to obtain the operating status of the air conditioner;

[0073] The judging module 220 is used to judge whether the output limit of the outdoor unit reaches the energy-saving target of the air conditioner when the running state of the air conditioner is in the energy-saving response state;

[0074] The control module 230 is used to control the indoor unit to reduce energy consumption when the output limit of the outdoor unit does not reach the energy reduction target of the air conditioner.

[0075] According to the control system of the air conditioner according to the embodiment of the present invention, when the operating state of the air conditioner is in the energy consumption reduction response state, the output of the outdoor unit is limited. In this process, it is judged whether the output limitation of the outdoor unit can enable the air conditioner to reach the energy consumption reduction target according to the real-time power of the air conditioner. If the air conditioner cannot reach the energy consumption reduction target, when the energy consumption reduction control effect is insufficient, the indoor unit can be involved in the energy consumption reduction control, thereby effectively reducing the real-time power of the air conditioner, so that the air conditioner reaches or is as close as possible to the energy consumption reduction target, and better meets the energy consumption response requirements.

[0076] For the specific definition of the control system of the air conditioner, please refer to the definition of the control method of the air conditioner above, which will not be repeated here. The various modules of the control system of the air conditioner can be implemented in whole or in part by software, hardware and a combination thereof.
