[0049] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0050] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of this application embodiment is: to control the operation of the fresh air unit and the air conditioner according to a preset control strategy and to reach a preset adjustment time interval; to control the operation of the fresh air unit and the air conditioner according to the current mode of the heat pump system, the current mode running time and the preset mode switching time interval.

[0052] In this embodiment, for ease of description, the following description will focus on identifying the heat pump system as the executing entity.

[0053] With the development of the air conditioning market, many air conditioning manufacturers have launched residential multi-split systems, which, in addition to the indoor units, include a central fresh air system. To facilitate user adjustments, manufacturers have developed control algorithms for the fresh air unit. These algorithms can automatically control fresh air and exhaust air, helping users regulate the indoor air environment. Most related technologies use the detection of indoor and outdoor temperature and humidity to determine and output control parameters to control the operation of the fresh air unit. However, frequent adjustments to the fresh air unit's mode during control can cause reliability issues with the air valves and generate noise.

[0054] This application provides a solution that enables the operation control of the fresh air unit and air conditioner during normal operation of the heat pump system by comprehensively considering the current mode, the length of time the current mode has been running, and the preset time interval for mode switching of the fresh air unit. This strategy of dynamically adjusting the switching time to select the fresh air unit mode can effectively avoid the reliability and noise caused by continuous switching of the air valve.

[0055] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device, multi-split air conditioner, or heat pump system capable of performing the above functions. The following description uses a heat pump system as an example to illustrate this embodiment and the subsequent embodiments.

[0056] Based on this, embodiments of this application provide a heat pump system control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the heat pump system control method of this application.

[0057] In this embodiment, the heat pump system control method includes steps S10 to S20:

[0058] Step S10: Control the fresh air unit and the air conditioner to operate according to the preset control strategy until the preset adjustment time interval is reached;

[0059] It should be noted that, firstly, when the heat pump system starts up, the system is controlled according to a pre-set control strategy to calculate the cumulative time during operation. After the preset time interval for mode switching is reached, the subsequent operation control logic is executed.

[0060] In one feasible implementation, in order to control the heat pump system to operate normally before mode switching, step S10 includes: obtaining preset control parameter combination information; and selecting a target control parameter combination from the preset control parameter combination information to control the operation of the fresh air unit and the air conditioner according to a preset control strategy.

[0061] It should be understood that when the fresh air unit and air conditioner are started, the multi-split system operates normally. During operation, at intervals T, the system executes the control steps of default operation and mode switching strategies.

[0062] In practice, the expected preset control parameter combination information is obtained. The control parameters include the operating mode of the fresh air unit, the windshield, and other information. The preset control parameter combination information includes multiple different parameter combinations, which are selected under the preset control strategy.

[0063] It should be noted that after determining the preset control parameter combination, the target control parameter combination is then selected from it to control the fresh air unit and the air conditioner.

[0064] In one feasible implementation, in order to accurately select a target control parameter combination according to preset control parameter combination information, the step of controlling the operation of the fresh air unit and the air conditioner according to a preset control strategy by selecting the target control parameter combination from the preset control parameter combination information includes: determining a weighted average wind speed based on the preset control parameter combination information; determining controllable wind speed range information based on the weighted average wind speed information; determining a target control parameter combination based on the controllable wind speed range information; and controlling the operation of the fresh air unit and the air conditioner according to the target control parameter combination and the preset control strategy.

[0065] It should be understood that, with N as the period, the actual operating control parameter combinations for the most recent N-1 periods are obtained from the preset control parameter combination information (for example, if N=4, then C3, C2, and C1 are obtained respectively, which are the parameter combinations for the most recent three periods).

[0066] In practice, after obtaining the actual operating control parameter combinations for the most recent N-1 cycles, the weighted average wind speed Favg of the most recent cycles is calculated. Then, the controllable wind speed range is calculated: Favg ± ΔF. The control parameter combination within this range is selected as the target control parameter combination. Here, ΔF refers to the adjustable wind speed range of the fresh air unit. After obtaining the target control parameter combination, the fresh air unit is controlled to operate, while the air conditioner operates according to the normal user settings.

[0067] Step S20: Control the operation of the fresh air unit and the air conditioner according to the current mode of the heat pump system, the current mode running time and the preset mode switching time interval.

[0068] It should be noted that after the fresh air unit and air conditioner are initialized and running, when the preset mode switching time interval is reached, the current mode of the heat pump system and the market that the current mode has been working are obtained. Finally, the operation control is carried out in combination with the preset mode switching time interval.

[0069] This embodiment provides a heat pump system control method. The method controls the operation of the fresh air unit and the air conditioner according to a preset control strategy until a preset adjustment time interval is reached. The operation control of the fresh air unit and the air conditioner is based on the current mode of the heat pump system, the duration of operation in the current mode, and a preset mode switching time interval. In this way, the operation control of the fresh air unit and the air conditioner is achieved by comprehensively considering the current mode, the duration of operation in the current mode, and the preset time interval for mode switching of the fresh air unit during normal operation of the heat pump system. This strategy of dynamically adjusting the switching time to select the fresh air unit mode effectively avoids reliability and noise issues caused by continuous valve switching.

[0070] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S20 includes steps S201 to S203:

[0071] Step S201: Compare the current mode running time of the heat pump system with the preset mode switching time interval;

[0072] It should be noted that the fresh air unit mode is controlled by a switching time length strategy (to avoid reliability and noise caused by continuous switching of the air valve). The preset mode switching time interval is set to Tm. Then, the current mode (heat exchange, internal circulation, strong) and running time are obtained. In the heat exchange mode, the fresh air unit exchanges heat between each room and the outside. In the internal circulation mode, the fresh air unit does not connect with the outside and only circulates air between each indoor space. In the strong mode, the air exchange between the indoor and outdoor spaces is carried out with a high wind speed exceeding a preset threshold. The preset threshold is a pre-set wind speed value, which is not limited in this embodiment.

[0073] It should be understood that the current running time of the heat pump system is compared with the preset mode switching time interval, and subsequent control is performed based on the comparison result.

[0074] In a feasible implementation, in order to perform corresponding control when the current mode running time is not less than the preset mode switching time interval, after step S201, the method further includes: when the current mode running time is greater than or equal to the preset mode switching time interval, selecting a target control parameter combination according to the current mode of the heat pump system; collecting indoor and outdoor temperature information and indoor and outdoor air pollution information; and performing operation control of the fresh air unit and the air conditioner according to the current mode, the indoor and outdoor temperature information and the indoor and outdoor air pollution information.

[0075] In practice, if the runtime is greater than or equal to Tm, the combination of control parameters that can be selected to change the mode or keep the mode unchanged can be selected by the user or determined by the system itself.

[0076] It should be noted that after the mode change is determined, indoor and outdoor temperature information, as well as indoor and outdoor air pollution information, are collected to switch the fresh air system mode based on the current mode, indoor and outdoor temperature, and indoor and outdoor air quality.

[0077] In one feasible implementation, in order to accurately control the operation of the fresh air unit based on temperature and air quality, the steps of controlling the operation of the fresh air unit and the air conditioner based on the current mode, the indoor and outdoor temperature information, and the indoor and outdoor air pollution information include: determining indoor and outdoor temperature assessment information based on the indoor and outdoor temperature information; determining indoor and outdoor air quality assessment information based on the indoor and outdoor air pollution information; determining the target speed of the fresh air unit and the air conditioner based on the indoor and outdoor temperature assessment information and the indoor and outdoor air quality assessment information; and controlling the operation of the fresh air unit and the air conditioner based on the target speed.

[0078] It should be understood that the first scenario involves the fresh air system operating in [internal circulation, heat exchange] mode. If it is currently running in internal circulation mode, and the outdoor air quality is poor or the outdoor temperature is high, it will continue to operate in internal circulation mode; if it is currently running in internal circulation mode, it will switch to heat exchange mode; if it is currently running in heat exchange mode, and the indoor temperature is high or the air quality is poor, it will continue to operate in heat exchange mode; if it is currently running in heat exchange mode, and the outdoor temperature is high, it will switch back to internal circulation mode. The automatic decision-making based on whether the mode remains unchanged or changes can be achieved by setting the above combination parameters for the fresh air system.

[0079] In a specific implementation, the second case is that the fresh air fan is in the [heat exchange, strong] mode. When currently operating in the heat exchange mode and the indoor air quality is poor or the indoor temperature is high, it switches to the strong mode; when currently operating in the heat exchange mode and the indoor air quality is poor or the indoor temperature is high, it continues to operate in the heat exchange mode, and the air damper is set to Favg + △F; when currently operating in the strong mode and the indoor air quality is poor, it continues to operate in the strong mode; when currently operating in the strong mode and switches to the heat exchange mode, the air damper is set to Favg - △F. Among them, based on the unchanged or changed mode, the automatic decision-making can execute the above fresh air fan combined parameter settings.

[0080] It should be noted that the second case is that the fresh air fan is in the [strong, internal circulation] mode. When currently operating in the strong mode, it switches to the internal circulation mode; when currently operating in the strong mode and the indoor air quality is poor or the temperature is high, it continues to operate in the strong mode; when currently operating in the internal circulation mode and the indoor air quality is poor or the indoor temperature is high, it switches to the strong mode; when currently operating in the internal circulation mode and the indoor air is normal and the temperature is appropriate, it continues to operate in the internal circulation mode. Among them, based on the unchanged or changed mode, the automatic decision-making can execute the above fresh air fan combined parameter settings.

[0081] Step S202, when the running duration of the current mode is less than the preset mode switching time interval, detect the indoor and outdoor pollution degree information of the heat pump system;

[0082] In a specific implementation, if the running duration < Tm, select the control parameter combination with the current mode unchanged, and then monitor the indoor and outdoor pollution degree information.

[0083] Step S203, perform the operation control of the fresh air fan and the air conditioner according to the current mode of the heat pump system and the indoor and outdoor pollution degree information.

[0084] It should be noted that after determining the current mode of the heat pump system, according to the level of indoor and outdoor pollution degree, the operation control of the fresh air fan and the air conditioner can be adjusted in a timely manner.

[0085] In a feasible implementation manner, in order to accurately adjust and control the fresh air fan, step S203 includes: determining the current control parameter combination according to the current mode of the heat pump system; determining the target air damper of the air conditioner according to the indoor and outdoor air pollution information; performing the operation control of the fresh air fan and the air conditioner according to the current control parameter combination and the target air damper.

[0086] It should be understood that if the running duration < Tm, select the control parameter combination with the current mode unchanged as the current control parameter combination.

[0087] In practice, the target air deflector is selected as follows: if outdoor pollution is detected to be severe, reduce the fresh air velocity and set the deflector to: Favg - ΔF. If indoor pollution is detected to be severe, increase the fresh air velocity and set the deflector to: Favg + ΔF.

[0088] This embodiment compares the current operating time of the heat pump system with a preset mode switching time interval. When the current operating time is less than the preset mode switching time interval, it detects the indoor and outdoor pollution levels of the heat pump system. Based on the current mode of the heat pump system and the indoor and outdoor pollution levels, it controls the operation of the fresh air unit and the air conditioner. In this way, it achieves a comprehensive analysis based on the current mode and its operating time, combined with the indoor and outdoor pollution levels, to determine the optimal mode switching and operation control scheme for the fresh air unit and air conditioner, reducing noise and the reliability impact of the air valve.

[0089] This application also provides a heat pump system control device, please refer to... Figure 3 The heat pump system control device includes:

The operation of the fresh air unit and the air conditioner is controlled based on the current mode of the heat pump system, the duration of operation in the current mode, and the preset mode switching time interval. In this way, the operation of the fresh air unit and the air conditioner is controlled by comprehensively considering the current mode, the duration of operation in the current mode, and the preset mode switching time interval of the fresh air unit during normal operation of the heat pump system.
