[0044] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] 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.

[0046] 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.

[0047] The main solution of this application embodiment is: to collect environmental parameter information of the heat pump system and calculate the dimensional time interval information of the heat pump system based on the environmental parameter information; to adjust the operating time interval of the fresh air unit based on the dimensional time interval information; and to control the operation of the fresh air unit according to the adjusted operating time interval.

[0048] In this embodiment, for ease of description, the following description will focus on identifying the heat pump system as the executing entity.

[0049] 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 units. These algorithms can automatically control the fresh air and exhaust air, helping users regulate the indoor air environment.

[0050] In the related art, most of them adopt the detection of indoor and outdoor temperature and humidity to make judgments and output control parameters, and the fresh air machine operates at fixed intervals. The existing fresh air machine control operates at a fixed time interval. If the time interval is too long, it will affect the control accuracy and accuracy of environmental regulation. If the time interval is set too short, it will increase the processing pressure of the server / CPU.

[0051] This application provides a solution. Through this method, it realizes the dynamic adjustment of the operation time interval evaluated in multiple different dimensions based on the environmental parameter information of the heat pump system. Finally, the time intervals of all dimensions are comprehensively considered to obtain the dynamically adjusted startup time interval of the fresh air machine. Considering the influencing factors of the linkage between the fresh air machine and the air conditioner, it improves the accuracy and control precision of the fresh air control environment, and avoids the increase of server processing pressure caused by too short time, bringing a better experience to users.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a multi-connected air conditioner, or a heat pump system that can implement the above functions. Hereinafter, taking the heat pump system as an example, this embodiment and the following embodiments will be described.

[0053] Based on this, the embodiment of this application provides a control method for a heat pump system, referring to Figure 1 , Figure 1 is a schematic flowchart of the first embodiment of the control method for the heat pump system of this application.

[0054] In this embodiment, the control method of the heat pump system includes steps S10 to S20:

[0055] Step S10, collect the environmental parameter information of the heat pump system, and calculate the dimension time interval information of the heat pump system according to the environmental parameter information;

[0056] It should be noted that the heat pump system in this embodiment includes an air conditioner and a fresh air machine. The air conditioner in it is a multi-connected air conditioner, including an outdoor unit and at least one indoor unit, and each indoor unit controls different rooms respectively. The fresh air machine, that is, the fresh air system, is a central fresh air system that belongs to the control of the heat pump system together with the air conditioner. Air outlets and inlets are provided in the rooms controlled by each indoor unit for air exchange in the room. In the solution of this embodiment, various air parameters are under the influence of the air conditioner, that is, in the solution of this embodiment, under the influence of the air conditioner, while changing parameters such as air temperature based on the air conditioner, the fresh air machine is correspondingly controlled to achieve linkage control.

[0057] It should be understood that, firstly, the indoor unit and fresh air unit are turned on, and the multi-split air conditioning system operates normally. Then, environmental parameter information around the outdoor and indoor units of the heat pump system is collected. The environmental parameter information includes, but is not limited to, temperature, enthalpy value, and the size of the room served by each indoor unit.

[0058] In practice, in order to accurately calculate the time interval for the operation and start-up of the heat pump system under different dimensions, it is necessary to perform calculations based on information such as temperature, enthalpy, and space size.

[0059] Step S20: Adjust the operating time interval of the fresh air unit according to the dimensional time interval information.

[0060] It should be noted that after obtaining the dimensional time interval information, the time interval for the final dynamic adjustment result is determined based on the dimensional time interval information.

[0061] In one feasible implementation, in order to obtain the time interval by setting the dimension more flexibly, step S20 includes: determining the dimensional time interval information of the heat pump system based on one or more of the temperature dimensional time interval, the enthalpy dimensional time interval, and the spatial dimensional time interval.

[0062] It should be understood that, according to the preset settings, the dimensional time interval information calculated by the scheme in this embodiment may include three dimensions: thermometer, enthalpy and space. However, it is not limited to all three dimensions being calculated. One or more of them can be used, thereby allowing for more flexible calculation of the dimensional time interval information.

[0063] In one feasible implementation, in order to accurately calculate the operating time interval of the fresh air unit, the number of the dimension time intervals is at least two. Step S20 includes: determining the dimension calculation weight and dimension time interval corresponding to each dimension based on the dimension time interval information; calculating the target time interval based on the dimension calculation weight and dimension time interval; and adjusting the operating time interval of the fresh air unit based on the target time interval.

[0064] It should be understood that after determining that time intervals have been calculated for all three dimensions, the first step is to determine the corresponding dimensional calculation weights for each dimension, as well as the calculated dimensional time intervals for each dimension, based on the dimensional time interval information. Dimensional time intervals include temperature time intervals, enthalpy time intervals, and spatial dimension time intervals. Calculations can also be performed when there are only two dimensions, using a similar approach that involves calculating weights and averages.

[0065] In practical implementation, assuming all three dimensions exist, the cloud assigns different weight factors to each dimension and calculates the final time interval. Assuming the weight of the temperature difference dimension is W1, the weight of the enthalpy dimension is W2, and the weight of the spatial dimension is W3, with T1 being the time interval for the temperature dimension, T2 for the enthalpy dimension, and T3 for the spatial dimension, the final target time interval is:

[0066] T_new = W1*T1 + W2*T2 + W3*T3.

[0067] It should be noted that after obtaining the target time interval, the optimized target time interval control device is used to achieve the linkage control of the fresh air unit and the air conditioner.

[0068] Step S30: Control the operation of the fresh air unit according to the adjusted operating time interval.

[0069] It should be understood that after determining the adjusted operating time interval, the adjusted operating time interval is configured into the fresh air unit, thereby controlling the fresh air unit to operate according to the adjusted operating time interval, and realizing the dynamic adjustment of the fresh air unit's operating time interval.

[0070] This embodiment provides a control method for a heat pump system. It collects environmental parameter information of the heat pump system and calculates dimensional time interval information based on this information. The operating time interval of the fresh air unit is adjusted according to this dimensional time interval information. The fresh air unit is then controlled to operate according to the adjusted operating time interval. This method achieves dynamic adjustment of operating time intervals based on environmental parameter information of the heat pump system, evaluating various dimensions. Finally, by comprehensively considering the time intervals of all dimensions, the dynamic adjustment start-up time interval of the fresh air unit is obtained. By comprehensively considering the influencing factors of the interaction between the fresh air unit and the air conditioning system, the accuracy and precision of the fresh air control environment are improved, and the server processing pressure is avoided due to excessively short time intervals, resulting in a better user experience.

[0071] 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 the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 Step S10 further includes steps S101 to S102:

[0072] Step S101: Determine the temperature dimension time interval based on the indoor and outdoor temperature information; and / or;

[0073] It should be noted that, firstly, indoor and outdoor temperature information, indoor and outdoor enthalpy information, and indoor space information are obtained based on environmental parameter information, including but not limited to (indoor temperature, outdoor temperature), (indoor enthalpy, outdoor enthalpy), and room size.

[0074] It should be understood that after obtaining the relevant parameter information of indoor and outdoor temperature, enthalpy, and indoor space, the time intervals in the three dimensions of temperature, enthalpy, and space are calculated respectively.

[0075] In practice, the first step is to obtain indoor and outdoor temperature information and use a pre-set algorithm to calculate the temperature dimension time interval. At the same time, the enthalpy dimension time interval is calculated based on the air enthalpy value of the space where the indoor and outdoor units are located, and the spatial dimension time interval is calculated based on the space size of the room where each indoor unit is located. Finally, the three are combined and summarized to obtain the dimension time interval information.

[0076] It should be noted that before calculating the time intervals for all dimensions, a fixed interval T is first preset.

[0077] By statistically analyzing the data, a suitable interval T is determined as the initial time interval and the basis for subsequent calculations.

[0078] In one feasible implementation, in order to accurately calculate the temperature dimension time interval, step S101 includes: obtaining the indoor and outdoor temperature difference of each indoor unit and calculating the average value of the indoor and outdoor temperature difference; determining the temperature dimension time interval based on the comparison result of the average value of the indoor and outdoor temperature difference and a preset indoor and outdoor temperature difference threshold.

[0079] It should be noted that the indoor and outdoor temperature difference threshold T1_out is set, and the adjustment range △T1 and upper and lower limits are adjusted; the average value of the indoor and outdoor temperature difference of each indoor unit is calculated; when the temperature difference is greater than n times the indoor and outdoor temperature difference threshold, the time interval T1 = T + n * △T1; if the temperature difference is less than or equal to the threshold, T1 = T.

[0080] Step S102: Determine the enthalpy dimension time interval based on the indoor and outdoor enthalpy information; and / or;

[0081] In one feasible implementation, in order to accurately calculate the enthalpy dimension time interval, step S102 includes: obtaining the indoor enthalpy and the outdoor enthalpy, and calculating the average value of the indoor and outdoor enthalpy; determining the enthalpy dimension time interval based on the comparison result of the average value of the indoor and outdoor enthalpy with a preset indoor and outdoor enthalpy threshold.

[0082] It should be understood that the indoor and outdoor threshold values ​​H are set, and the adjustment range ΔT2 and its upper and lower limits are set. The average value of each indoor enthalpy value and the outdoor enthalpy value are calculated. When the enthalpy difference is greater than n times the threshold, the time interval T2 = T + n * ΔT2; if the enthalpy difference is less than or equal to the threshold, T2 = T. Here, the adjustment range ΔT2 and its upper and lower limits refer to the maximum and minimum enthalpy values ​​that each indoor unit can control within the room, as well as their range.

[0083] Step S103: Determine the spatial dimension time interval based on the indoor space information.

[0084] In one feasible implementation, in order to accurately calculate the spatial dimension time interval, step S103 includes: obtaining the spatial values ​​of each room in the room and calculating the average room space value; determining the spatial dimension time interval based on the comparison result of the average room space value and the preset room space threshold.

[0085] In practical implementation, a room space threshold S is set, along with an adjustment range ΔT3 and upper and lower limits. When the average space value of each room is greater than the set threshold by n times, the time interval T3 = T + n * ΔT3; if the space value is less than the threshold, T3 = T. The adjustment range ΔT3 and upper and lower limits refer to the minimum and maximum space size at which each indoor unit can accurately control the temperature.

[0086] This embodiment determines the time interval for the temperature dimension based on the indoor and outdoor temperature information; and / or, the time interval for the enthalpy dimension based on the indoor and outdoor enthalpy information; and / or, the time interval for the spatial dimension based on the indoor space information. In this way, dynamic time interval adjustments are calculated based on three dimensions: temperature, enthalpy, and space, resulting in a more accurate time interval and optimized control performance.

[0087] This application also provides a control device for a heat pump system; please refer to... Figure 3 The control device for the heat pump system includes:

[0089] Interval calculation module 20 is used to adjust the operating time interval of the fresh air unit according to the dimensional time interval information.

[0090] The operation control module 30 is used to control the operation of the fresh air unit according to the adjusted operating time interval.

[0091] This embodiment collects environmental parameter information of the heat pump system and calculates the dimensional time interval information of the heat pump system based on the environmental parameter information. It then adjusts the operating time interval of the fresh air unit according to the dimensional time interval information and controls the operation of the fresh air unit according to the adjusted operating time interval. In this way, it realizes the calculation of dynamic adjustment operating time intervals based on the environmental parameter information of the heat pump system under multiple different dimensions of evaluation. Finally, it comprehensively considers the time intervals of all dimensions to obtain the dynamic adjustment start-up time interval of the fresh air unit. By comprehensively considering the influence factors of the linkage between the fresh air unit and the air conditioning, it improves the accuracy and precision of the fresh air control environment and avoids excessively short time intervals that would increase the server processing pressure, thus providing a better user experience.
