Description

Technical Field

[0001] This application relates to the technical field of intelligent air conditioners, for example, to methods, devices, air conditioners, and storage media for air conditioner control. Background Art

[0002] As a common intelligent device for adjusting the temperature and humidity of the indoor environment, air conditioners have been widely used. In related technologies, air conditioners can adopt a vapor compression refrigeration cycle to achieve the adjustment of indoor temperature, which has the advantage of high energy efficiency. However, when cooling at high temperatures or heating at low temperatures, the air conditioner may have problems such as low cooling capacity or heating capacity.

[0003] Currently, two sets of semiconductor components can be added to the air conditioner. Each set of semiconductor components is respectively connected to the indoor unit and the outdoor unit of the air conditioner. In this way, when the air conditioner operates in cooling mode, one set of semiconductor components can be controlled to operate, pre-cooling the inlet pipeline of the evaporator in the indoor unit of the air conditioner, and pre-heating the inlet pipeline of the condenser in the outdoor unit of the air conditioner, thereby increasing the cooling capacity of the air conditioner; when the air conditioner operates in heating mode, the other set of semiconductor components can be controlled to operate, pre-heating the inlet pipeline of the evaporator in the indoor unit of the air conditioner, and pre-cooling the inlet pipeline of the condenser in the outdoor unit of the air conditioner, thereby increasing the heating capacity of the air conditioner, meeting the cooling and heating requirements under harsh working conditions.

[0004] It can be seen that after the air conditioner is configured with two sets of semiconductor components, the cooling capacity or heating capacity of the air conditioner can be increased by controlling the operation of the semiconductor components, meeting the cooling and heating requirements under harsh working conditions. However, due to material limitations, after the semiconductor components are connected and operated for a long time, the cooling or heating efficiency decreases and the reliability decreases. As a result, the operation efficiency and reliability of the air conditioner are affected, and the power consumption of the air conditioner is relatively large when the semiconductor components are operated for a long time. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a comprehensive review, nor is it intended to identify key / important constituent elements or delineate the scope of protection of these embodiments. Instead, it serves as a preamble to the subsequent detailed description.

[0006] Embodiments of the present disclosure provide a method, a device, an air conditioner, and a storage medium for air conditioner control to solve the technical problem of excessive power consumption of the air conditioner under harsh working conditions. The air conditioner includes two sets of semiconductor components.

[0007] In some embodiments, the method includes:

[0008] When the running time of the air conditioner operating in the current working mode reaches the set start time, obtain the average running frequency of the air conditioner compressor within the set start time, and obtain the first average indoor temperature value of the air conditioner operating in the current working mode within the first set duration, and obtain the first absolute average temperature difference between the first average indoor temperature value and the target indoor temperature value;

[0009] When the first absolute average temperature difference is greater than or equal to the second set temperature value, determine the first running frequency of the air conditioner compressor matching the average running frequency, and the first running state of the current semiconductor component, where the current semiconductor component matches the current working mode;

[0010] Control the air conditioner compressor to run at the first running frequency, and control the current semiconductor component to run at the first running state.

[0011] In some embodiments, the air conditioner includes the above-mentioned device for air conditioner control.

[0012] In some embodiments, the storage medium stores program instructions that, when running, execute the above-mentioned method for air conditioner control.

[0013] The method, device, and air conditioner for air conditioner control provided by the embodiments of the present disclosure can achieve the following technical effects:

[0014] Two sets of semiconductor components are configured in the air conditioner, and when the air conditioner starts to operate in the current working mode and reaches the set start time, and the air conditioner compressor operates at a high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large, the operating parameters and states of the air conditioner compressor and the semiconductor component can be adjusted. In this way, by controlling the operation of the semiconductor component, the cooling capacity or heating capacity of the air conditioner is improved, the cooling and heating efficiency is improved, and the semiconductor component is controlled only when certain conditions are met, reducing the power consumption of the air conditioner.

[0029] In the embodiments of the present disclosure, two sets of semiconductor components are added to the air conditioner. Each set of semiconductor components is respectively connected to the indoor unit and the outdoor unit of the air conditioner. In this way, the refrigerating capacity or the heating capacity of the air conditioner can be increased by controlling the operation of the semiconductor components, which not only meets the refrigerating and heating requirements under harsh working conditions, but also improves the refrigerating and heating efficiency of the air conditioner.

[0030] Figure 1 FIG. is a schematic structural diagram of an air conditioner provided by the embodiments of the present disclosure. As Figure 1 shown, the air conditioner includes: an indoor unit 100 of the air conditioner, an outdoor unit 200 of the air conditioner, and two sets of semiconductor components, namely a first semiconductor component 310 and a second semiconductor component 320.

[0031] The first refrigerating end 311 of the first semiconductor component 310 is connected to the indoor unit 100 of the air conditioner, and the first heating end 312 of the first semiconductor component 310 is connected to the outdoor unit 200 of the air conditioner.

[0032] The second refrigerating end 321 of the second semiconductor component 320 is connected to the outdoor unit 200 of the air conditioner, and the second heating end 322 of the second semiconductor component 320 is connected to the indoor unit 100 of the air conditioner.

[0033] In the embodiments of the present disclosure, the semiconductor component can utilize the thermoelectric effect of the semiconductor. By connecting two metals with different physical properties with a conductor and connecting a direct current, it can achieve a decrease in temperature at one end and an increase in temperature at the other end, and is commonly used for cooling of electronic components and micro heat exchangers. There are multiple sets of hot spot elements inside the semiconductor component, and a refrigerating and heating effect with a hot end of 40-50 °C, a cold end of -10 to -20 °C, and a temperature difference of 60 °C can be achieved.

[0034] Among them, after the first semiconductor component 310 is started to operate, there are multiple sets of hot spot elements in the first refrigerating end 311, and the temperature can be reduced, while there are also multiple sets of hot spot elements in the first heating end 312, but the temperature can be increased. After the second semiconductor component 320 is started to operate, the temperature can also be reduced and increased at both ends respectively. Among them, there are multiple sets of hot spot elements in the second refrigerating end 321, and the temperature can be reduced, while there are also multiple sets of hot spot elements in the second heating end 322, and the temperature can be increased.

[0035] In some embodiments, the first semiconductor component 310 and the second semiconductor component 320 can cooperate with the indoor evaporator and the outdoor condenser of the air conditioner to pre-cool and pre-heat the evaporator inlet pipeline and the condenser inlet pipeline respectively. As Figure 1 shown, one end of the first refrigerating end 311 is connected to the evaporator of the indoor unit 100 of the air conditioner through an indoor connector 110, and the other end is connected to one end of the first heating end 312 through a first semiconductor component connecting pipe 313. The other end of the first heating end 312 is connected to the condenser of the outdoor unit 200 of the air conditioner through an outdoor connector 210.

[0036] One end of the second heat end 322 is connected to the evaporator of the indoor unit 100 of the air conditioner through the indoor connector 110, and the other end is connected to one end of the second cold end 321 through the second semiconductor component connecting pipe 323. The other end of the second cold end 321 is connected to the condenser of the outdoor unit 200 of the air conditioner through the outdoor connector 210.

[0037] It can be seen that the two ends of the first semiconductor component and the second semiconductor component are arranged oppositely, and opposite temperature changes can be achieved after starting operation. That is, during refrigeration, when the first semiconductor component is turned on, the inlet pipeline of the evaporator in the indoor unit of the air conditioner can be precooled, while the inlet pipeline of the condenser in the outdoor unit of the air conditioner can be preheated, realizing precooling on the indoor side and preheating on the outdoor side; during heating, when the second semiconductor component is turned on, the inlet pipeline of the evaporator in the indoor unit of the air conditioner can be preheated, while the inlet pipeline of the condenser in the outdoor unit of the air conditioner can be precooled, realizing preheating on the indoor side and precooling on the outdoor side. Thus, the indoor cooling capacity can be increased when the outside temperature is high, and the indoor heating capacity can be increased when the outside temperature is low, meeting the refrigeration and heating requirements under harsh working conditions.

[0038] In some embodiments, exhaust fans for strengthening air circulation can be arranged at both ends of the two groups of semiconductor components, which can strengthen the heat exchange between both ends of the semiconductor components and the indoor / outdoor sides, thereby realizing the compensation of the system's cooling capacity / heating capacity. As Figure 1 shown, the air conditioner may further include: four exhaust fans; among them, the first exhaust fan 410 is located on the first cold end 311, the second exhaust fan 420 is located on the first heat end 312, the third exhaust fan 430 is located on the second heat end 322, and the fourth exhaust fan 440 is located on the second cold end 321.

[0039] Of course, in some embodiments, the air conditioner may also have only one, two or three exhaust fans, which can be located at any one end of any semiconductor component.

[0040] After the air conditioner is configured with two groups of semiconductor components, or configured with two groups of semiconductor components and their corresponding exhaust fans, the cooling capacity or heating capacity of the air conditioner can be improved by controlling the operation of the semiconductor components, which not only meets the refrigeration and heating requirements under harsh working conditions, but also improves the efficiency of the air conditioner's refrigeration and heating.

[0041] In an embodiment of the present disclosure, when the air conditioner starts running in the current working mode and reaches the set start time, and the air conditioner compressor keeps running at a high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large, the operating parameters and states of the air conditioner compressor and the semiconductor components can be adjusted. That is, when the indoor temperature is far from the target temperature value and the compressor runs at a high frequency for a long time, the semiconductor components can be turned on to provide supplementary cooling or heating for the system. Thus, the power of the air conditioner can be flexibly controlled. While improving the cooling or heating capacity of the air conditioner and the cooling and heating efficiency by controlling the operation of the semiconductor components, the power consumption of the air conditioner is reduced.

[0042] Figure 2 It is a schematic flowchart of a method for controlling an air conditioner provided by an embodiment of the present disclosure. The air conditioner can be configured with two sets of semiconductor components as described above, or configured with two sets of semiconductor components and their corresponding exhaust fans. As Figure 2 shown, the process for controlling the air conditioner includes:

[0043] Step 2001: When the running time of the air conditioner running in the current working mode reaches the set start time, obtain the average running frequency of the air conditioner compressor within the set start time, and obtain the first average indoor temperature value of the air conditioner running in the current working mode within the first set duration, and obtain the first absolute average temperature difference between the first average indoor temperature value and the target indoor temperature value.

[0044] In an embodiment of the present disclosure, the air conditioner starts running in the current working mode. At this time, vapor compression operation can be adopted, that is, the operation of the air conditioner compressor is controlled according to the collected indoor and outdoor temperature values. The current working mode can include: cooling, heating, dehumidification and other modes. A set start time can be preset. After the air conditioner starts running and reaches the set start time, the working state of the air conditioner is relatively stable. Therefore, the set start time can be determined according to the performance parameters of the air conditioner, and can be 15, 20, 25, 30 minutes, etc.

[0045] If the running time of the air conditioner running in the current working mode reaches the set start time, for example: it has run for 20 minutes, it indicates that the air conditioner is in a stable running state. And the average running frequency Pp of the air conditioner compressor within the set start time can be obtained. At this time, the first average indoor temperature value of the air conditioner running in the current working mode within the first set duration can be obtained, and the first absolute average temperature difference between the first average indoor temperature value and the target indoor temperature value can be obtained.

[0046] In the embodiments of the present disclosure, an indoor temperature acquisition device may be configured in the area where the air conditioner is located. Thus, after the air conditioner runs to the set start time, the first average indoor temperature value Trp1 can be obtained according to the indoor temperature values collected by the indoor temperature acquisition device within the recorded first set duration. The first set duration may be 3, 5, 8, or 10 minutes, or it may also be zero, that is, the first average indoor temperature value may be the obtained instant indoor temperature value.

[0047] After obtaining the first average indoor temperature value Trp1, the first absolute average temperature difference │Trp1 - Tset│ between the first average indoor temperature value Trp1 and the target indoor temperature value Tset can be obtained.

[0048] Step 2002: When the first absolute average temperature difference is greater than or equal to the second set temperature value, determine the first operating frequency of the air conditioner compressor matched with the average operating frequency, and the first operating state of the current semiconductor component, where the current semiconductor component is matched with the current working mode.

[0049] Generally, when the air conditioner operates in modes such as cooling, heating, and dehumidifying, the larger the first absolute average temperature difference, the greater the required cooling capacity or heating capacity. At this time, it is necessary to start the semiconductor component to operate. When the first absolute average temperature difference is relatively small, the air conditioner compressor can simply continue to operate in the existing state. Therefore, a relatively large second set temperature value can be preset, for example: 4.5°C, 5°C, or 6°C, etc. In this way, when the first absolute average temperature difference is greater than or equal to the second set temperature value, it is necessary to adjust the operating parameters and states of the air conditioner compressor and the semiconductor component according to the average operating frequency of the air conditioner compressor within the set start time. Thus, by controlling the operation of the semiconductor component, the cooling capacity or heating capacity of the air conditioner is improved, and the cooling and heating efficiency is improved.

[0050] Since the first cooling end of the first semiconductor component is connected to the indoor unit of the air conditioner, and the first heating end of the first semiconductor component is connected to the outdoor unit of the air conditioner, after the first semiconductor component starts to operate, indoor pre-cooling and outdoor side pre-heating can be achieved; while the second cooling end of the second semiconductor component is connected to the outdoor unit of the air conditioner, and the second heating end of the second semiconductor component is connected to the indoor unit of the air conditioner. Therefore, after the second semiconductor component starts to operate, indoor side pre-heating and outdoor side pre-cooling can be achieved.

[0051] It can be seen that according to the connection relationship of the first semiconductor component and the second semiconductor component, the current semiconductor component matched with the current working mode can be determined. When the current working mode is the cooling mode, the current semiconductor component is the first semiconductor component; when the current working mode is the heating mode, the current semiconductor component is the second semiconductor component.

[0052] In an embodiment of the present disclosure, when the first absolute average temperature difference is greater than or equal to the second set temperature value, the operating parameters and states of the air-conditioning compressor and the semiconductor components can be adjusted according to the average operating frequency of the air-conditioning compressor within the set startup time. That is, the first operating frequency of the air-conditioning compressor matching the average operating frequency and the first operating state of the current semiconductor components can be determined. Specifically, it may include: when the average operating frequency is less than the first set frequency, the air-conditioning compressor is frequency-increased, and the increased operating frequency is determined as the first operating frequency, and the shutdown state is determined as the first operating state of the current semiconductor components; when the average operating frequency is greater than or equal to the first set frequency and less than the second set frequency, the first operating frequency of the air-conditioning compressor is determined according to the startup adjustment strategy, and the startup operating state is determined as the first operating state of the current semiconductor components; when the average operating frequency is greater than or equal to the second set frequency, the obtained operating frequency of the air-conditioning compressor is determined as the first operating frequency, and the startup operating state is determined as the first operating state of the current semiconductor components.

[0053] In this way, when the air conditioner starts and runs to reach the set startup time, if the first absolute average temperature difference is greater than or equal to the second set temperature value, for example, when the first absolute average temperature difference │Trp1-Tset│≥5.5°C, it indicates that the indoor temperature difference is relatively large. At this time, the operating parameters and states of the air-conditioning compressor and the semiconductor components need to be adjusted according to the average operating frequency.

[0054] Among them, a first set frequency and a second set frequency can be preset. The second set frequency can be greater than the first set frequency. For example, the first set frequency can be 45%, 50%, or 55% etc. of the maximum operating frequency of the air-conditioning compressor, and the second set frequency can be 70%, 80%, 85%, or 90% etc. of the maximum operating frequency of the air-conditioning compressor. In this way, when the average operating frequency is less than the first set frequency, it means that the operating frequency of the air-conditioning compressor is not high enough, and the operating frequency of the air-conditioning compressor can be increased through frequency-increasing processing. Thus, the cooling capacity or heating capacity of the air conditioner can be improved. That is, at this time, the semiconductor components do not need to be started, and only by adjusting the operating frequency of the air-conditioning compressor, the cooling capacity or heating capacity of the air conditioner can be adjusted, thereby improving the efficiency of the air conditioner. Therefore, the shutdown state can be determined as the first operating state of the current semiconductor components, and the air-conditioning compressor needs to be frequency-increased, and the increased operating frequency is determined as the first operating frequency.

[0055] If the average operating frequency is greater than or equal to the first set frequency, it indicates that the air conditioner has maintained a high-frequency operation during the set startup time, but the indoor temperature value still fails to reach the target indoor temperature value. At this time, it is necessary to turn on the semiconductor component for auxiliary refrigeration or heating, that is, to adjust the refrigerating capacity or heating capacity of the air conditioner by turning on the semiconductor component, so as to improve the efficiency of the air conditioner, and then the startup operation state can be determined as the first operation state of the current semiconductor component. Moreover, in some embodiments, the operating frequency of the compressor can be further adjusted to adjust the refrigerating capacity or heating capacity of the air conditioner. Among them, when the average operating frequency is greater than or equal to the first set frequency and less than the second set frequency, the operating frequency of the air conditioner is not particularly high. At this time, the operating frequency of the compressor can be adjusted according to the preset startup adjustment strategy of the air conditioner, that is, the first operating frequency of the air conditioner compressor is determined according to the startup adjustment strategy. If the average operating frequency is greater than or equal to the second set frequency, the air conditioner is operating at a high frequency. Therefore, only the operating frequency of the air conditioner needs to be maintained unchanged, that is, the obtained operating frequency of the air conditioner compressor is determined as the first operating frequency.

[0056] For example, in the case of the air conditioner operating in the cooling mode, if the first absolute average temperature difference is greater than or equal to the second set temperature value, such as │Trp1 - Tset│≥5°C, the operating parameters and states of the air conditioner compressor and the semiconductor component can be adjusted according to the average operating frequency of the air conditioner compressor during the set startup time. Among them, if the average operating frequency Pp is greater than or equal to the first set frequency, the first operating state of the first semiconductor component can be determined as the startup operation state. In this way, after starting the first semiconductor component to operate, the evaporator inlet pipeline in the indoor unit of the air conditioner can be precooled, and the condenser inlet pipeline in the outdoor unit of the air conditioner can be preheated. Thus, the refrigerating capacity of the air conditioner is improved, and the refrigeration efficiency of the air conditioner is improved. In the case of the air conditioner operating in the heating mode, if the first absolute average temperature difference is greater than or equal to the second set temperature value, such as │Trp1 - Tset│≥5°C, among which, if the average operating frequency Pp is greater than or equal to the first set frequency, the first operating state of the second semiconductor component is determined as the startup operation state. In this way, after starting the second semiconductor component to operate, the evaporator inlet pipeline in the indoor unit of the air conditioner can be preheated, and the condenser inlet pipeline in the outdoor unit of the air conditioner can be precooled. Thus, the heating capacity of the air conditioner is improved, and the heating efficiency of the air conditioner is improved.

[0057] Step 2003: Control the air conditioner compressor to operate at the first operating frequency, and control the current semiconductor component to operate in the first operating state.

[0058] After determining the first operating frequency of the air-conditioning compressor and the first operating state of the current semiconductor component, the air-conditioning compressor can be controlled to operate at the first operating frequency, and the current semiconductor component can be controlled to operate at the first operating state.

[0059] Among them, when the first absolute average temperature difference is greater than or equal to the second set temperature value, controlling the air-conditioning compressor to operate at the first operating frequency may include: if the average operating frequency is less than the first set frequency, the air-conditioning compressor is frequency-increased, and the air-conditioning compressor is controlled to operate at the increased operating frequency. If the average operating frequency is greater than or equal to the first set frequency and less than the second set frequency, the frequency of the air-conditioning compressor can be adjusted according to the startup adjustment strategy, and the air-conditioning compressor is controlled to operate at the adjusted operating frequency. If the average operating frequency is greater than or equal to the second set frequency, the air-conditioning compressor needs to be controlled to operate at a constant operating frequency.

[0060] In some embodiments, when the first absolute average temperature difference is greater than or equal to the second set temperature value and the average operating frequency is greater than or equal to the first set frequency, the semiconductor component can be always controlled to be in the startup operation state. However, due to material limitations, long-term continuous operation of the semiconductor component will reduce the component reliability, and long-term operation of the semiconductor will also increase the power consumption of the air conditioner. Therefore, when the first absolute average temperature difference is greater than or equal to the second set temperature value and the average operating frequency is greater than or equal to the first set frequency, the operating time of the current semiconductor component in the startup operation state in the air conditioner can be 5, 8, 10, or 15 minutes, etc.

[0061] Alternatively, in some embodiments, the semiconductor component does not operate continuously for a long time. The operating cycle can be set as the unit operation, and within the set operating cycle, the semiconductor component operates for a period of time and stops for the remaining time, that is, the set operating cycle includes: operating time and stop time. For example: the set operating cycle can be 20 minutes. In this way, during the periodic operation of the semiconductor component, it can operate in the way of stopping for 10 minutes after operating for 10 minutes. At this time, both the operating time and the stop time are 10 minutes. Or, the set operating cycle can be 30 minutes. In this way, during the periodic operation of the semiconductor component, it can operate in the way of stopping for 10 minutes after operating for 20 minutes, etc. At this time, the operating time is 20 minutes and the stop time is 10 minutes.

[0062] Therefore, in this embodiment, controlling the current semiconductor component to operate in the first operating state may include: controlling the current semiconductor component matching the current operating mode to operate in the first operating state for one cycle. Specifically, it may include: when the first absolute average temperature difference is greater than or equal to the second set temperature value and the average operating frequency is greater than or equal to the first set frequency, within the operating time of the set operating cycle of the semiconductor component, controlling the current semiconductor component to be in the startup operating state; while within the stop time of the set operating cycle of the semiconductor component, controlling the current semiconductor component to be in the shutdown state. For example: when │Trp1 - Tset│≥4.5°C and the average operating frequency Pp≥50% of the maximum operating frequency Pmax, only within 10 minutes of the 20 - minute set operating cycle of the semiconductor component, control the current semiconductor component to be in the startup operating state, and then, the current semiconductor component can be controlled to be in the shutdown state. That is, the current semiconductor component can be shut down after only 10 minutes of startup operation. In this way, by controlling the operation of the semiconductor component, the cooling capacity or heating capacity of the air conditioner is increased, and while improving the cooling and heating efficiency, the power consumption of the air conditioner is reduced.

[0063] Of course, in some embodiments, the semiconductor can operate periodically. However, it is also possible not to perform periodic control on the current semiconductor component, that is, the time when the current semiconductor component of the air conditioner is in the startup operating state may not be the operating time of the set operating cycle. Specific examples are not given here.

[0064] In the embodiments of the present disclosure, the power of the semiconductor component is adjustable, and the corresponding output cooling capacity or heating capacity is also different. Thus, under the same control input voltage, according to different control input currents, the semiconductor component can output different cooling capacities or heating capacities. In some embodiments, the semiconductor component corresponds to two or more operating gears. The greater the control input current of the semiconductor component, the higher the corresponding operating gear and the more output energy. For example: when the control input voltage is 220V and the control input currents are 0.5A, 1A, and 1.5A respectively, the semiconductor component corresponds to three gears: low, medium, and high. Of course, the semiconductor component may also only correspond to two gears: low and high, etc.

[0065] It can be seen that in some embodiments, when the current semiconductor component is in the startup and running state, it can correspond to different operating gears. Therefore, controlling the current semiconductor component to operate in the first operating state includes: when the average operating frequency is greater than or equal to the first set frequency, determining the first operating gear of the current semiconductor component corresponding to the average operating frequency; within the operating time of the set operating cycle of the semiconductor component, controlling the current semiconductor component to operate in the first operating gear. Among them, the semiconductor component corresponds to two or more operating gears, and the greater the control input current of the semiconductor component, the higher the corresponding operating gear. Of course, within the stop time of the set operating cycle of the semiconductor component, the current semiconductor component can be controlled to be in the shutdown state.

[0066] Among them, determining the first operating gear of the current semiconductor component corresponding to the average operating frequency includes: when the average operating frequency is greater than or equal to the first set frequency and less than the second set frequency, determining the second gear as the first operating gear of the current semiconductor component; when the average operating frequency is greater than or equal to the second set frequency, determining the third gear as the first operating gear of the current semiconductor component. Among them, the control input current of the semiconductor component corresponding to the third gear is greater than the control input current of the semiconductor component corresponding to the second gear, and the control input current of the semiconductor component corresponding to the second gear is greater than the control input current of the semiconductor component corresponding to the first gear.

[0067] For example: the second set temperature value is 4°C, the first set frequency is 40% of the highest frequency Pmax, and the second set frequency is 65% of the highest frequency Pmax. In this way, when │Trp1 - Tset│≥4°C, if 40% of Pmax ≤ average operating frequency Pp < 65% of Pmax, the second gear can be determined as the first operating gear of the current semiconductor component; and if 65% of Pmax ≤ Pp, the third gear can be determined as the first operating gear of the current semiconductor component.

[0068] Of course, the semiconductor component corresponds to two, four, five, etc. operating gears, and the first operating gear of the current semiconductor component can also be determined according to the first average outdoor temperature value, which will not be described in detail here.

[0069] After determining the first operating gear of the current semiconductor component, in this way, the current semiconductor component can be controlled to operate in the first operating gear, or within a set time period, the current semiconductor component can be controlled to operate in the first operating gear. In some embodiments, within the operating time of the set operating cycle of the semiconductor component, the current semiconductor component can be controlled to operate in the first operating gear.

[0070] It can be seen that in the embodiments of the present disclosure, when the air conditioner starts to operate in the current working mode and reaches the set start time, and the air conditioner compressor operates at a relatively high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large, the operating parameters and states of the air conditioner compressor and the semiconductor components can be adjusted. In this way, by controlling the operation of the semiconductor components, the cooling capacity or heating capacity of the air conditioner is increased, and the cooling and heating efficiency is improved. Moreover, the semiconductor components are controlled only when certain conditions are met, reducing the power consumption of the air conditioner. And for different average operating frequencies of the compressor, there are different operating gears of the semiconductor components, that is, corresponding to different output energies of the semiconductor components, thereby further accelerating the cooling or heating efficiency of the air conditioner.

[0071] When the operating time of the air conditioner operating in the current working mode reaches the set start time, and within the operating time of the set operating cycle of the semiconductor component, after controlling the current semiconductor component to operate in the first operating gear, the air conditioner can be continuously controlled to operate in the vapor compression mode, and the operation of the semiconductor component is no longer controlled. However, to improve the efficiency of the air conditioner in adjusting the temperature, in some embodiments, after controlling the current semiconductor component to operate in the first operating gear, the operation of the current semiconductor component and the operation of the air conditioner compressor can also be periodically controlled according to the obtained current average indoor temperature value within the current set duration, which may include: when the current semiconductor component is in the shutdown state and the duration of the air conditioner operating in the current mode reaches the preset sampling duration, obtaining the current average indoor temperature value within the current set duration in the area where the air conditioner is located, and obtaining the current absolute average temperature difference between the current average indoor temperature value and the target indoor temperature value; determining the current operating frequency of the air conditioner compressor and the current operating state of the current semiconductor component that match the current absolute average temperature difference; controlling the air conditioner compressor to operate at the current operating frequency, and controlling the current semiconductor component to operate in the current operating state.

[0072] Within the operating time of the set operating cycle of the semiconductor component, after controlling the current semiconductor component to operate in the first operating gear, the current semiconductor component can be in the shutdown state. At this time, the air conditioner operates in the current mode. When the duration of the air conditioner operating in the current mode reaches the preset sampling duration, the preset sampling duration can be 5, 10, 15, 25 minutes, etc. That is, within the preset sampling duration, the semiconductor component has not been started and operated, and is in the shutdown state, and the air conditioner also operates in the current working mode all the time. At this time, the indoor temperature value can be continuously sampled, and the indoor temperature values collected by the indoor temperature acquisition device within the set duration are recorded. Then, according to the recorded indoor temperature values and the set duration, the average indoor temperature value can be obtained.

[0073] Of course, after the air conditioner in the embodiment of the present disclosure controls the current semiconductor component to operate in the first operating gear, automatic continuous control can be performed. Therefore, the current set duration corresponds to the current average indoor temperature value. The set duration can be 1 minute, 5 minutes, 10 minutes, 20 minutes, etc. In some embodiments, the current set duration can be zero. At this time, the current average indoor temperature value is the real-time current indoor temperature value collected by the indoor temperature acquisition device.

[0074] After obtaining the current average indoor temperature value Trp, the current absolute average temperature difference │Trp - Tset│ between the current average indoor temperature value Trp and the target indoor temperature value Tset can be obtained.

[0075] During the process of periodic automatic continuous control, the current operating frequency of the air conditioner compressor and the current operating state of the current semiconductor component can be determined according to the current absolute average temperature difference, as well as the operating parameters and states of the air conditioner compressor and the semiconductor component in the previous control corresponding to the previous set duration.

[0076] In some embodiments, when the previous operating gear of the current semiconductor component is the highest gear, it may include: when the current absolute average temperature difference is greater than or equal to the first set temperature value, determining the obtained operating frequency of the air conditioner compressor as the current operating frequency, and determining the highest gear as the current operating gear in the starting operating state of the current semiconductor component; when the current absolute average temperature difference is less than the first set temperature value, if the obtained operating frequency of the air conditioner compressor is greater than or equal to the second set frequency, performing a frequency reduction process on the air conditioner compressor, and determining the reduced operating frequency as the current operating frequency, and determining the highest gear as the current operating gear in the starting operating state of the current semiconductor component; when the current absolute average temperature difference is less than the first set temperature value, if the obtained operating frequency of the air conditioner compressor is less than the second set frequency, determining the obtained operating frequency of the air conditioner compressor as the current operating frequency, and performing a gear reduction process on the current semiconductor component, and determining the reduced operating gear as the current operating gear in the starting operating state of the current semiconductor component.

[0077] That is, when the previous operating gear of the current semiconductor component is the highest gear and the current absolute average temperature difference is relatively small, the cooling capacity or heating capacity of the air conditioner can be reduced by means of frequency reduction or gear reduction. While improving the cooling capacity or heating capacity of the air conditioner by controlling the operation of the semiconductor component and improving the cooling and heating efficiency, the power consumption of the air conditioner is reduced.

[0078] In some embodiments, when the previous operating gear of the current semiconductor component is not the highest gear, determining the current operating frequency of the air-conditioning compressor that matches the current absolute average temperature difference, and the current operating state of the current semiconductor component may include: when the current absolute average temperature difference is greater than or equal to the second set temperature value, determining the obtained operating frequency of the air-conditioning compressor as the current operating frequency, and performing a gear-up process on the current semiconductor component, and determining the increased operating gear as the current operating gear in the starting operating state of the current semiconductor component; when the current absolute average temperature difference is less than the second set temperature value and greater than or equal to the first set temperature value, determining the obtained operating frequency of the air-conditioning compressor as the current operating frequency, and determining the previous operating gear as the current operating gear in the starting operating state of the current semiconductor component; when the current absolute average temperature difference is less than the first set temperature value, determining the current operating frequency of the air-conditioning compressor according to the start-up adjustment strategy, and performing a gear-down process on the current semiconductor component, and determining the decreased operating gear as the current operating gear in the starting operating state of the current semiconductor component.

[0079] That is, when the previous operating gear of the current semiconductor component is not the highest gear and the current absolute average temperature difference is large, a gear-up process can be performed to increase the cooling or heating capacity of the semiconductor component. When the current absolute average temperature difference is relatively large, the operating parameters of the air-conditioning compressor and the semiconductor component may not be adjusted; when the current absolute average temperature difference is relatively small, a gear-down process can be performed. In this way, while improving the cooling or heating capacity of the air conditioner and the cooling and heating efficiency by controlling the operation of the compressor and the semiconductor component, the power consumption of the air conditioner is reduced.

[0080] Certainly, when the previous operating gear is the lowest gear and the current absolute average temperature difference is less than the first set temperature value and a gear-down process needs to be performed, the shutdown state can be determined as the current operating state of the current semiconductor component.

[0081] The first set temperature value is smaller than the second set temperature value, and can be determined according to the location of the air conditioner and the performance of the air conditioner.

[0082] After determining the current operating frequency of the air-conditioning compressor that matches the current absolute average temperature difference and the current operating state of the current semiconductor component, the air-conditioning compressor can be controlled to operate at the current operating frequency, and the current semiconductor component can be controlled to operate in the current operating state.

[0083] For example: when the first set temperature value is 1.5 °C and the second set temperature value is 4.5 °C, and the previous operating gear of the current semiconductor component is the highest gear, i.e., the third gear, if │Trp - Tset│≥1.5 °C, the operating states of the air-conditioning compressor and the current semiconductor component can be kept unchanged, and the operating frequency of the air-conditioning compressor is still controlled to be unchanged. During the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to operate in the third gear. Of course, during the stop time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to be in the shutdown state. If │Trp - Tset│<1.5 °C, at this time, the operating frequency of the air-conditioning compressor needs to be obtained. If the obtained operating frequency of the air-conditioning compressor is greater than or equal to the second set frequency, it indicates that the air-conditioning compressor is operating at a high frequency. Since Trp is already relatively close to Tset, at this time, the air-conditioning compressor can be frequency-reduced. For example, the frequency can be reduced at a rate of 1HZ / 1min, and the air-conditioning compressor is controlled to operate at the reduced operating frequency. The highest gear can still be determined as the current operating gear in the starting operating state of the current semiconductor component, that is, during the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is still controlled to operate in the third gear. If the obtained operating frequency of the air-conditioning compressor is less than the second set frequency, the compressor frequency may not be adjusted, and the current semiconductor component needs to be downshifted. During the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to operate in the second gear.

[0084] When the previous operating gear of the current semiconductor component is not the highest gear, that is, it may be the second gear or the first gear, if │Trp - Tset│≥4.5 °C, the current absolute average temperature difference is relatively large, and the cooling or heating capacity of the air conditioner needs to be increased. Therefore, an upshift process is required, that is, the operating frequency of the air-conditioning compressor is kept unchanged, and the current semiconductor component can be upshifted. During the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to operate at the increased operating gear. That is, if the previous operating gear is the second gear, it can be increased to the third gear for operation; if the previous operating gear is the first gear, it can be increased to the second gear for operation. If 1.5 °C≤│Trp - Tset│<4.5 °C, the operating states of the air-conditioning compressor and the current semiconductor can be maintained unchanged. If │Trp - Tset│<1.5 °C, it indicates that the current absolute average temperature difference is very small. Then the air-conditioning compressor is adjusted according to the startup adjustment strategy configured for air-conditioning startup, that is, the air-conditioning compressor is controlled to operate according to the startup adjustment strategy, and a downshift process is also required. During the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to operate at the reduced gear.

[0085] Among them, if the previous operating gear is the lowest gear, for example, the first gear, when downshifting is performed, that is, when │Trp-Tset│<1.5°C, the current semiconductor component can be controlled to be in the shutdown state.

[0086] In the semiconductor component of the air conditioner, a corresponding exhaust fan may be configured. The exhaust fan can strengthen air circulation and enhance the heat exchange between both ends of the semiconductor component and the indoor / outdoor side, thereby realizing the compensation of the system's cooling capacity / heating capacity. Therefore, in some embodiments, when the current semiconductor component is in the startup operation state, the corresponding exhaust fan on the current semiconductor component can also be controlled according to the current working mode.

[0087] Among them, when the first semiconductor component is in the startup operation state, control the first exhaust fan and the second exhaust fan configured on the first semiconductor component to operate; when the second semiconductor component is in the startup operation state, control the third exhaust fan and the fourth exhaust fan configured on the second semiconductor component to operate. Among them, in the air conditioner, the first exhaust fan is located on the first cooling end, the second exhaust fan is located on the first heating end, the third exhaust fan is located on the second heating end, and the fourth exhaust fan is located on the second cooling end.

[0088] When the semiconductor component stops running, to further reduce energy consumption, the corresponding exhaust fan can also be turned off. In some embodiments, when the current semiconductor component is in the shutdown state, control the corresponding exhaust fan on the current semiconductor component to turn off. That is, when the first semiconductor component stops running, control the first exhaust fan and the second exhaust fan configured on the first semiconductor component to stop running; when the second semiconductor component stops running, control the third exhaust fan and the fourth exhaust fan configured on the second semiconductor component to stop running.

[0089] Moreover, when the semiconductor component of the air conditioner is in the shutdown state, the air conditioner can still adopt the vapor compression refrigeration cycle to adjust the indoor temperature.

[0090] Currently, the air conditioner has a communication function. In this way, the air conditioner can also control the operation of the semiconductor component according to the received instruction. In some embodiments, when receiving the semiconductor switch instruction sent by the configured control application APP terminal, control the switch operation of the semiconductor component in the air conditioner according to the semiconductor switch instruction. In this way, the user can control the switch of the semiconductor component through the APP, improving the intelligence of the air conditioner and the user experience.

[0091] Next, the operation process will be integrated into specific embodiments to illustrate the air conditioner control process provided by the embodiments of the present disclosure.

[0092] In this embodiment, the air conditioner can be as Figure 1As shown, it includes two sets of semiconductor components and four exhaust fans. Moreover, the first set temperature value stored in the air conditioner is 2°C, and the second set temperature value is 5°C. Also, the semiconductor components correspond to three operating gears, and the output energy of the third gear is greater than that of the second gear, while the output energy of the second gear is greater than that of the first gear. The first set frequency is 50% of the maximum frequency Pmax of the air conditioner compressor, and the second set frequency is 80% of the maximum frequency Pmax of the air conditioner compressor. And, the set start time can be 20 min, the set duration and the first set duration can both be 10 min, the set operating cycle of the semiconductor components can be 20 min, and the operating time of the set operating cycle is 10 min; and the set start time can be the operating time of the set operating cycle, which is also 10 min; the preset sampling duration can also be 10 min. The current operating mode of the air conditioner is the cooling mode, and the corresponding current semiconductor component is the first semiconductor component.

[0122] It can be seen that in this embodiment, two sets of semiconductor components are configured in the air - conditioner. And when the air - conditioner starts to run in the current working mode and reaches the set startup time, and the air - conditioner compressor keeps running at a high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large, the operating parameters and states of the air - conditioner compressor and the semiconductor components can be adjusted. In this way, by controlling the operation of the semiconductor components, the cooling capacity or heating capacity of the air - conditioner is improved, the cooling and heating efficiency is increased, and the semiconductor components are controlled only when certain conditions are met, reducing the power consumption of the air - conditioner.

[0123] According to the above - mentioned process for air - conditioner control, a device for air - conditioner control can be constructed.

The current operating mode of the air conditioner is the heating mode, and the corresponding second semiconductor component is the second semiconductor component.

[0151] Figure 5 is a schematic structural diagram of a device for air-conditioning control provided by the embodiments of the present disclosure. As Figure 5As shown, the air conditioner control device includes: a first acquisition module 4100, a first determination module 4200, a first control module 4300, a second acquisition module 4400, a second determination module 4500, and a second control module 4600.

[0152] When the air conditioner is turned on and the heating mode is started, when the heating operation time of the air conditioner reaches 20 minutes, the first acquisition module 4100 can acquire the average operation frequency P of the air conditioner compressor within 20 minutes, and can record the indoor temperature value of the air conditioner operating in the heating mode within 12 minutes, obtain the first average indoor temperature value Trp1 within 12 minutes, and according to the current average indoor temperature value Trp1 and the target indoor temperature value Tset, obtain the current absolute average temperature difference │Trp1 - Tset│.

[0153] In this way, if │Trp1 - Tset│ < 5.5°C, the air conditioner operates normally in heating mode. If │Trp1 - Tset│ ≥ 5.5°C and the average operation frequency Pp < 50% of Pmax, the first determination unit 4210 in the first determination module 4200 can perform a frequency increase process on the air conditioner compressor, determine the increased operation frequency as the first operation frequency, and determine the shutdown state as the first operation state of the second semiconductor component. Thus, the first control module 4300 can perform a frequency increase process on the air conditioner compressor, control the air conditioner compressor to operate at the increased operation frequency, and control the second semiconductor component to be in the shutdown state.

[0154] If │Trp1 - Tset│ ≥ 5.5°C and 50% ≤ Pp < 80% of Pmax, the second determination unit 4220 in the first determination module 4200 determines the first operation frequency of the air conditioner compressor according to the startup adjustment strategy, determines the startup operation state as the first operation state of the second semiconductor component, and the first gear determination unit 4310 in the first control module 4300 determines the second gear as the first operation gear of the second semiconductor component.

[0155] If │Trp1 - Tset│≥5.5°C and 80% of Pmax ≤ Pp, the third determination unit 4230 in the first determination module 4200 will determine the operating frequency of the air conditioner compressor obtained as the first operating frequency, determine the first operating state of the second semiconductor component as the startup operating state, and the first gear determination unit 4310 will determine the third gear as the first operating gear of the second semiconductor component.

[0156] Thus, the first control unit 4320 in the first control module 4300 can control the air conditioner compressor to operate at the first operating frequency, control the second semiconductor component to operate at the first operating gear, and control the first exhaust fan on the first heating end of the second semiconductor component and the second exhaust fan on the first heating end to operate. Also, when the operating time reaches 15 minutes of the set operating cycle of the semiconductor component, the first control unit 4320 can control the second semiconductor component to be in the shutdown state, and control the third exhaust fan on the second heating end of the second semiconductor component and the fourth exhaust fan on the second heating end to close. And save the first operating gear as the previous operating gear.

[0157] After controlling the second semiconductor component to operate at the first operating gear, the second semiconductor component can be continuously controlled. Among them, when the second semiconductor component is in the shutdown state and the duration of the air conditioner in the current mode operating state reaches the preset sampling duration of 15 minutes, the second acquisition module 4400 acquires the current average indoor temperature value Trp within the current set duration of 12 minutes in the area where the air conditioner is located, and obtains the current absolute average temperature difference │Trp - Tset│ between the current average indoor temperature value and the target indoor temperature value.

[0158] Moreover, when the previously obtained operating gear is the third operating gear, if │Trp - Tset│≥2.5°C, the fourth determination unit 4510 in the second determination module 4500 can determine the obtained operating frequency of the air-conditioning compressor as the current operating frequency of the air-conditioning compressor, and determine the third gear as the current operating gear in the starting operating state of the second semiconductor component. If │Trp - Tset│<2.5°C, but the obtained operating frequency P of the air-conditioning compressor is ≥80% of Pmax, the fifth determination unit 4520 can perform a frequency reduction process on the air-conditioning compressor, and determine the reduced operating frequency as the current operating frequency of the air-conditioning compressor, and determine the third gear as the current operating gear in the starting operating state of the second semiconductor component. If │Trp - Tset│<2.5°C, but the obtained operating frequency P of the air-conditioning compressor is <80% of Pmax, the sixth determination unit 4530 will determine the obtained operating frequency of the air-conditioning compressor as the current operating frequency of the air-conditioning compressor, and perform a gear reduction process on the second semiconductor component, and determine the second operating gear as the current operating gear in the starting operating state of the second semiconductor component.

[0159] When the previously obtained operating gear is not the third operating gear, if │Trp - Tset│≥5.5°C, the seventh determination unit 4540 can determine the obtained operating frequency of the air-conditioning compressor as the current operating frequency of the air-conditioning compressor, and perform a gear up process on the second semiconductor component, and determine the increased operating gear as the current operating gear in the starting operating state of the second semiconductor component. If 2.5°C≤│Trp - Tset│<5.5°C, the eighth determination unit 4550 can determine the obtained operating frequency of the air-conditioning compressor as the current operating frequency, and determine the previously obtained operating gear as the current operating gear in the starting operating state of the second semiconductor component. If │Trp - Tset│<2.5°C, the ninth determination unit 4560 determines the current operating frequency of the air-conditioning compressor according to the start-up adjustment strategy, and performs a gear reduction process on the second semiconductor component, and determines the reduced operating gear as the current operating gear in the starting operating state of the second semiconductor component. Among them, if the previously obtained operating gear is the lowest gear, when performing a gear reduction process on the second semiconductor component, the ninth determination unit 4560 determines the shutdown state as the current operating state of the second semiconductor component.

[0160] Thus, the second control module 4600 can control the air-conditioning compressor to operate at the current operating frequency, control the second semiconductor component to operate at the current operating gear, and control the first exhaust fan on the first heating end of the second semiconductor component to operate, and the second exhaust fan on the first heating end to operate. Also, when the operating time reaches 15 minutes of the set operating cycle of the semiconductor component, the second control module 4600 can control the second semiconductor component to be in the shutdown state, and control the third exhaust fan on the second heating end of the second semiconductor component to be turned off, and the fourth exhaust fan on the second heating end to be turned off. And save the current operating gear as the previous operating gear.

[0161] It can be seen that in this embodiment, two sets of semiconductor components are configured in the air conditioner. In this way, when the device for air-conditioning control starts the current working mode and runs to the set start time, and the air-conditioning compressor keeps running at a high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large, the operating parameters and states of the air-conditioning compressor and the semiconductor components can be adjusted. In this way, by controlling the operation of the semiconductor components, the cooling capacity or heating capacity of the air conditioner is improved, and the cooling and heating efficiency is improved. Moreover, the semiconductor components are controlled only when certain conditions are met, reducing the power consumption of the air conditioner.
