technical field

The present application relates to the technical field of intelligent air conditioners, for example, to methods and devices for air conditioner control, air conditioners and storage media.

Background technique

Air conditioners have been widely used as a common smart device for adjusting the temperature and humidity of indoor environments. In the related art, the air conditioner can use a vapor compression refrigeration cycle to adjust the indoor temperature, which has the advantage of high energy efficiency. However, the air conditioner may have a problem of low cooling or heating capacity when cooling at high temperature or heating at low temperature.

At present, two groups of semiconductor components can be added to the air conditioner, and each group of semiconductor components is connected to the air conditioner internal unit and the air conditioner external unit respectively. In this way, the cooling operation of the air conditioner can control the operation of a group of semiconductor components. The evaporator inlet pipeline of the air conditioner is precooled, and the condenser inlet pipeline of the air conditioner external unit is preheated, which improves the cooling capacity of the air conditioner; while the air conditioner is heating, it can control the operation of another group of semiconductor components.

In the embodiment of the present disclosure, two groups of semiconductor components are added to the air conditioner, and each group of semiconductor components is respectively connected to the air conditioner internal unit and the air conditioner external unit. The heat not only meets the cooling and heating needs under severe working conditions, but also improves the cooling and heating efficiency of the air conditioner.

Fig. 1 is a schematic structural diagram of an air conditioner provided by an embodiment of the present disclosure. As shown in FIG. 1 , the air conditioner includes: an air conditioner inner unit 100 , an air conditioner outer unit 200 and two groups of semiconductor components, namely a first semiconductor component 310 and a second semiconductor component 320 .

The first cooling terminal 311 of the first semiconductor component 310 is connected to the air conditioner indoor unit 100 , and the first heating terminal 312 of the first semiconductor component 310 is connected to the air conditioner external unit 200 .

The second cooling terminal 321 of the second semiconductor component 320 is connected to the air conditioner external unit 200 , and the second heating terminal 322 of the second semiconductor component 320 is connected to the air conditioner internal unit 100 .

In the embodiment of the present disclosure, the semiconductor component can use the thermoelectric effect of the semiconductor to connect two metals with different physical properties with a conductor and connect a direct current, so that the temperature at one end can be lowered and the temperature at the other end can be increased. It is often used in electronic components and micro heat exchange Cooling of the appliance. There are multiple sets of hotspot elements inside the semiconductor components, which can realize the cooling and heating effect of 40-50°C at the hot end, -10--20°C at the cold end, and a temperature difference of 60°C.

Wherein, after the first semiconductor component 310 is turned on and operated, there are multiple sets of hotspot elements in the first cooling end 311 to lower the temperature, and there are also multiple sets of hotspot elements in the first heating end 312 to increase the temperature. After the second semiconductor component 320 is turned on and running, the two ends can also achieve temperature reduction and temperature rise respectively. Among them, there are multiple groups of hotspot elements in the second cooling end 321, which can realize temperature reduction, while the second heating end 322 There are also multiple sets of hot spot elements to achieve temperature rise.

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 preheat the inlet pipeline of the evaporator and the inlet pipeline of the condenser respectively. . As shown in FIG. 1 , one end of the first cooling end 311 is connected to the evaporator of the air conditioner 100 through the indoor connector 110 , and the other end is connected to one end of the first heating end 312 through the first semiconductor component connecting pipe 313 . The other end of the first heating end 312 is connected to the condenser of the air conditioner external unit 200 through the outdoor connecting piece 210 .

One end of the second heating end 322 is connected to the evaporator of the air conditioner 100 through the indoor connector 110, and the other end is connected to one end of the second cooling end 321 through the second semiconductor assembly connecting pipe 323, and the other end of the second cooling end 321 One end is connected with the condenser of the air conditioner external unit 200 through the outdoor connecting piece 210 .

It can be seen that the arrangement of the two ends of the first semiconductor component and the second semiconductor component is reversed, and opposite temperature changes can be realized after the start-up operation. That is, when cooling, the first semiconductor component is turned on to pre-cool the evaporator inlet pipeline in the air conditioner's inner unit, and preheat the condenser inlet pipeline in the air conditioner's outer unit, so as to realize indoor precooling and outdoor side cooling. Preheating; when heating, turn on the second semiconductor component to preheat the evaporator inlet pipeline in the air conditioner’s inner unit, and precool the condenser inlet pipeline in the air conditioner’s outer unit to achieve indoor preheating. The heat and the outdoor side are pre-cooled, so that the indoor cooling capacity can be increased when the external temperature is high, and the indoor heating capacity can be increased when the external temperature is low, which meets the cooling and heating needs under severe working conditions.

In some embodiments, both ends of the two groups of semiconductor components can be equipped with exhaust fans to enhance air circulation, which can strengthen the heat exchange between the two ends of the semiconductor components and the indoor/outdoor side, so as to realize the cooling capacity/heating capacity of the system. compensate. As shown in Figure 1, the air conditioner can also include: four exhaust fans; wherein, the first exhaust fan 410 is located on the first cooling end 311, the second exhaust fan 420 is located on the first heating end 312, and the third exhaust fan 420 is located on the first heating end 312. The exhaust fan 430 is located on the second heating end 322 , and the fourth exhaust fan position 440 is located on the second cooling end 321 .

Of course, in some embodiments, there may be an air conditioner or only one, two or three exhaust fans, which may be located at any end of any semiconductor component.

After the air conditioner is equipped with two sets of semiconductor components, or equipped with two sets 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 demand for cooling and heating under certain conditions also improves the efficiency of air conditioning cooling and heating.

In the embodiment of the present disclosure, when the air conditioner starts to run in the current working mode and reaches the set start time, and the air conditioner compressor keeps running at high frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still relatively large , you can adjust the operating parameters and status of the air conditioner compressor and semiconductor components, that is, the indoor temperature is far from the target temperature value, and after the compressor has been running at high frequency for a long time, you can turn on the semiconductor components to provide supplementary cooling for the system or Therefore, the power of the air conditioner can be flexibly controlled, and the cooling capacity or heating capacity of the air conditioner can be increased by controlling the operation of semiconductor components, and the cooling and heating efficiency can be improved while reducing the power consumption of the air conditioner.

Fig. 2 is a schematic flowchart of an air conditioner control method provided by an embodiment of the present disclosure. As mentioned above, the air conditioner can be configured with two sets of semiconductor components, or equipped with two sets of semiconductor components and their corresponding exhaust fans. As shown in Figure 2, the processes used for air conditioning control include:

Step 2001: When the running time of the air conditioner 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 current work mode within the first set time period The first average indoor temperature value of the air conditioner is operated, and the first absolute average temperature difference between the first average indoor temperature value and the target indoor temperature value is obtained.

In the embodiment of the present disclosure, the air conditioner is started to run in the current working mode. At this time, the 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 may include: cooling, heating, dehumidification and other modes. A set start time can be set in advance. After the air conditioner starts running and reaches the set start time, the air conditioner will be in a relatively stable working state. Therefore, the set start time can be determined according to the performance parameters of the air conditioner, which can be 15, 20, 25, 30 minutes and so on.

If the running time of the air conditioner in the current working mode reaches the set start time, for example: it has been running for 20 minutes, it indicates that the air conditioner is in a stable running state, and the average operating 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 operating in the current working mode within the first set time period 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.

In the embodiment of the present disclosure, the area where the air conditioner is located can be equipped with an indoor temperature acquisition device, so that after the air conditioner runs to the set start time, the indoor temperature collected by the indoor temperature acquisition device can be recorded within the first set time period according to the record. value, the first average indoor temperature value Trp1 can be obtained. The first set duration may be 3, 5, 8, or 10 minutes, or may also be zero, that is, the first average indoor temperature value may be the acquired instant indoor temperature value.

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.

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 that matches the average operating frequency, and the first operating state of the current semiconductor components , where the current semiconductor component matches the current working mode.

Generally, when the air conditioner is operating in cooling, heating, dehumidification and other modes, the greater the first absolute average temperature difference, the greater the required cooling or heating capacity. At this time, semiconductor components need to be activated for operation. While the first absolute average temperature difference is relatively small, it is only necessary for the air conditioner compressor to continue to operate in the current state. Therefore, a relatively large second set temperature value can be preset, for example: 4.5°C, 5°C, or 6°C, etc., so that when the first absolute average temperature difference is greater than or equal to the second set temperature value In some cases, it is necessary to adjust the operating parameters and status of the air conditioner compressor and semiconductor components according to the average operating frequency of the air conditioner compressor within the set start time, so as to increase the cooling capacity of the air conditioner by controlling the operation of semiconductor components or The heating capacity improves the cooling and heating efficiency.

Since the first cooling terminal of the first semiconductor component is connected to the air conditioner internal unit, and the first heating terminal of the first semiconductor component is connected to the external unit of the air conditioner, in this way, after the first semiconductor component starts running, the indoor forecasting can be realized. Cold and outdoor preheating; while the second cooling terminal of the second semiconductor component is connected to the external unit of the air conditioner, and the second heating terminal of the second semiconductor component is connected to the internal unit of the air conditioner, therefore, after the second semiconductor component starts running , It can realize indoor preheating and outdoor precooling.

It can be seen that, according to the connection relationship between the first semiconductor component and the second semiconductor component, the current semiconductor component matching the current working mode can be determined. Wherein, when the current working mode is cooling mode, the current semiconductor component is the first semiconductor component; when the current working mode is heating mode, the current semiconductor component is the second semiconductor component.

In the embodiment of the present disclosure, when the first absolute average temperature difference is greater than or equal to the second set temperature value, the air conditioner compressor and The operating parameters and status of the semiconductor components can determine the first operating frequency of the air-conditioning compressor that matches the average operating frequency, and the current first operating state of the semiconductor components. Specifically, it may include: when the average operating frequency is less than the first set In the case of a fixed frequency, the air conditioner compressor is frequency-up processed, 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 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 conditioner compressor is determined according to the start-up adjustment strategy, and the start-up operation state is determined as the first set frequency of the current semiconductor components. An operating state; when the average operating frequency is greater than or equal to the second set frequency, the obtained operating frequency of the air conditioner compressor is determined as the first operating frequency, and the starting operating state is determined as the current semiconductor component The first operating state.

In this way, when the start-up of the air conditioner reaches the set start 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 status of the air conditioner compressor and semiconductor components need to be adjusted according to the average operating frequency.

Wherein, a first set frequency and a second set frequency can be preset, wherein the second set frequency can be greater than the first set frequency, for example: the first set frequency can be 45% of the maximum operating frequency of the air conditioner compressor %, 50%, or 55%, etc., and the second set frequency can be 70%, 80%, 85%, or 90% of the maximum operating frequency of the air conditioner compressor, etc. In this way, when the average operating frequency is lower than the first set frequency, it means that the operating frequency of the air conditioner compressor is not high, and the operating frequency of the air conditioner compressor can also be increased through frequency up processing, thereby increasing the cooling capacity of the air conditioner or Heating capacity, that is, at this time, there is no need to start semiconductor components, just adjust the cooling capacity or heating capacity of the air conditioner by adjusting the operating frequency of the air conditioner compressor, thereby improving the efficiency of the air conditioner. Therefore, it can be determined that the off state is the first operating state of the current semiconductor components, and it is necessary to perform frequency up processing on the air conditioner compressor, and determine the increased operating frequency as the first operating frequency.

And 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 start time, but the indoor temperature value is still lower than the target indoor temperature value. At this time, it is necessary to turn on the semiconductor components Perform auxiliary cooling or heating, that is, adjust the cooling or heating capacity of the air conditioner by turning on the semiconductor components, thereby improving the efficiency of the air conditioner, and then determine the start-up operation state as the first operation state of the current semiconductor components. Moreover, in some embodiments, the operating frequency of the compressor can be further adjusted to adjust the cooling capacity or heating capacity of the air conditioner. Wherein, 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 compressor can be adjusted according to the preset starting adjustment strategy of the air conditioner The operating frequency is to determine the first operating frequency of the air conditioner compressor according to the start-up adjustment strategy. If the average operating frequency is greater than or equal to the second set frequency, the air conditioner is operating at high frequency. Therefore, only the operating frequency of the air conditioner needs to be kept unchanged, and the acquired operating frequency of the air conditioner compressor is determined to be the first operating frequency.

For example, when the air conditioner is running in refrigeration 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, according to the set start time, The average operating frequency of the air-conditioning compressor, and adjust the operating parameters and status of the air-conditioning compressor and semiconductor components. Wherein, 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 start-up operating state. In this way, after the first semiconductor component is started to operate, the air conditioner can The inlet pipeline of the evaporator in the indoor unit is precooled, and the inlet pipeline of the condenser in the outdoor unit of the air conditioner is preheated, thereby increasing the cooling capacity of the air conditioner, thereby improving the cooling efficiency of the air conditioner. In the case of air-conditioning and heating mode operation, if the first absolute average temperature difference is greater than or equal to the second set temperature value, such as: │Trp1-Tset│≥5℃, wherein, if the average operating frequency Pp is greater than or equal to the first set frequency, then the first operating state of the second semiconductor component is determined as the start-up operating state, so that after the second semiconductor component is started to run, the evaporator inlet pipe in the air conditioner internal unit can be The air conditioner is preheated, and the condenser inlet pipeline in the air conditioner external unit is precooled, thereby increasing the heating capacity of the air conditioner, thereby improving the heating efficiency of the air conditioner.

Step 2003: Control the air conditioner compressor to run at the first operating frequency, and control the current semiconductor components to run at the first operating state.

After determining the first operating frequency of the air conditioner compressor and the first operating state of the current semiconductor components, the air conditioner compressor can be controlled to operate at the first operating frequency, and the current semiconductor components can be controlled to operate at the first operating state.

Wherein, the first absolute average temperature difference is greater than or equal to the second set temperature value, controlling the air conditioner compressor to run at the first operating frequency may include: if the average operating frequency is less than the first set frequency, the air conditioner compressor is raised Frequency processing to control the air conditioner compressor to run 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 conditioner compressor can be adjusted according to the start-up adjustment strategy, and the air conditioner compressor is controlled to operate at the adjusted operating frequency. If the average running frequency is greater than or equal to the second set frequency, the air conditioner compressor needs to be controlled to run at a constant running frequency.

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 components can always be controlled to be in the start-up operation state, however, Semiconductor components are limited by materials, and long-term continuous operation will reduce the reliability of components. Moreover, long-term operation of semiconductors 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 time that the current semiconductor components in the air conditioner are in the start-up state can be 5, 8, 10, or 15 minutes and so on.

Or, in some embodiments, the semiconductor components do not run continuously for a long time, and the operation period can be set as a unit to operate, and within the set operation period, the semiconductor components operate for a period of time, and the semiconductor components operate for the rest of the time. Stopping, that is, setting the running cycle includes: running time and stopping time. For example: set the operating cycle to be 20 minutes. In this way, during the periodic operation of semiconductor components, it can be operated in the manner of running for 10 minutes and then stopping for 10 minutes. At this time, the operating time and stopping time are both 10 minutes. Alternatively, the set operation period can be 30 minutes, so that during the periodic operation of semiconductor components, it can be operated in the manner of running for 20 minutes and then stopping for 10 minutes, etc. At this time, the operation time is 20 minutes, and the stop time is 10 minutes.

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, during the operating time of the set operating cycle of the semiconductor components Within the control period, the current semiconductor components are controlled to be in the start-up operation state; and within the stop time of the set operation cycle of the semiconductor components, the current semiconductor components are controlled to be in the shutdown state. For example: │Trp1-Tset│≥4.5℃, and the average operating frequency Pp≥50% of the maximum operating frequency Pmax, only need to control the current semiconductor components to start within 10 minutes within 20 minutes of the set operating cycle of the semiconductor components The running state, then, can control the current semiconductor components to be in the shutdown state. That is to say, the current semiconductor components only need to be started and run for 10 minutes before they can be turned off. In this way, the cooling or heating capacity of the air conditioner can be increased by controlling the operation of the semiconductor components, and the cooling and heating efficiency can be improved while reducing the power consumption of the air conditioner.

Of course, in some embodiments, the semiconductor can be operated periodically, but the current semiconductor components may not be periodically controlled, that is, the time that the current semiconductor components of the air conditioner are in the start-up operation state may not be the operation of the set operation cycle. Time, no specific examples.

In the embodiment of the present disclosure, the power of the semiconductor components is adjustable, and the corresponding output cooling or heat is also different. Therefore, under the same control input voltage, according to different control input currents, the semiconductor components can output different cooling. volume or heat. In some embodiments, the semiconductor component corresponds to two or more operating gears, and the greater the control input current of the semiconductor component is, the higher the corresponding operating gear is, and the greater the output energy is. For example: the control input voltage is 220V, and the control input current is 0.5A, 1A, and 1.5A respectively. In this way, semiconductor components correspond to three gears of low, medium, and high. Of course, semiconductor components can also only correspond to low and high gears and so on.

It can be seen that, in some embodiments, when the current semiconductor components are in the starting operation state, they can correspond to different operating gears. Therefore, controlling the current semiconductor components to operate in the first operating state includes: when the average operating frequency is greater than or equal to the first In the case of setting the frequency, determine the first operating gear of the current semiconductor component corresponding to the average operating frequency; within the running time of the set operating cycle of the semiconductor component, control the current semiconductor component to the first operating gear run. Wherein, the semiconductor components correspond to two or more operating gears, and the greater the control input current of the semiconductor components is, the higher the corresponding operating gears are. Of course, within the stop time of the set operating period of the semiconductor component, the current semiconductor component can be controlled to be in a shutdown state.

Wherein, determining the first operating gear of the current semiconductor components corresponding to the average operating frequency includes: determining the second gear when the average operating frequency is greater than or equal to the first set frequency and less than the second set frequency is the first operating gear of the current semiconductor components; when the average operating frequency is greater than or equal to the second set frequency, determine the third gear as the first operating gear of the current semiconductor components. Wherein, the control input current of the semiconductor components corresponding to the third gear is greater than the control input current of the semiconductor components corresponding to the second gear, and the control input current of the semiconductor components corresponding to the second gear is greater than the control input current of the semiconductor components corresponding to the first gear. Control input current for semiconductor components.

For example: the second set temperature is 4°C, the first set frequency is 40% of the maximum frequency Pmax, and the second set frequency is 65% of the maximum frequency Pmax. In this way, when │Trp1-Tset│≥4℃, 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 components; and If 65% of Pmax≤Pp, the third gear can be determined as the first operating gear of the current semiconductor components.

Of course, the semiconductor components correspond to two, four, five, etc. operating gears, and the corresponding first operating gears of the current semiconductor components can also be determined according to the first average outdoor temperature value, which will not be described in detail. .

The first operating gear of the current semiconductor component is determined, so that the current semiconductor component can be controlled to run at the first operating gear, or, within a set time period, the current semiconductor component can be controlled to run at the first operating gear . In some embodiments, the current semiconductor component can be controlled to operate at the first operating gear within the operating time of the set operating cycle of the semiconductor component.

It can be seen that in the embodiment of the present disclosure, when the air conditioner starts 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 If it is still relatively large, the operating parameters and status of the air conditioner compressor and semiconductor components can be adjusted. In this way, the cooling capacity or heating capacity of the air conditioner can be increased by controlling the operation of the semiconductor components, the cooling and heating efficiency can be improved, and certain requirements can be met. Conditions to control the semiconductor components, reducing the power consumption of the air conditioner. Moreover, different average operating frequencies of the compressors correspond to different operating gears of the semiconductor components, that is, correspond to different output energies of the semiconductor components, thereby further speeding up the cooling or heating efficiency of the air conditioner.

When the running time of the air conditioner in the current working mode reaches the set start time, and within the running time of the set running cycle of the semiconductor components, after the current semiconductor components are controlled to run in the first operating gear, the air conditioner can be continued to be controlled Operate in vapor compression mode and no longer control the operation of semiconductor components. However, in order to improve the efficiency of air conditioning temperature regulation, in some embodiments, after the current semiconductor components are controlled to operate in the first operating gear, the current average indoor temperature value within the current set time period can also be periodically controlled. The operation of the current semiconductor components and the operation of the air conditioner compressor may include: when the current semiconductor components are in the shutdown state and the duration of the air conditioner in the current mode of operation reaches the preset sampling time, obtain the current status of the area where the air conditioner is located. Set the current average indoor temperature value within the duration, and obtain the current absolute average temperature difference between the current average indoor temperature value and the target indoor temperature value; determine the current operating frequency of the air conditioner compressor that matches the current absolute average temperature difference , and the current operating state of the current semiconductor components; controlling the air conditioner compressor to operate at the current operating frequency, and controlling the current semiconductor components to operate at the current operating state.

During the operating time of the set operating cycle of the semiconductor components, after the current semiconductor components are controlled to run at the first operating gear, the current semiconductor components can be in the shutdown state. At this time, the air conditioner operates in the current mode. When the duration of the current mode running state reaches the preset sampling time, the preset sampling time can be 5, 10, 15, 25 minutes, etc. Turn off the shutdown state, and the air conditioner has been running in the current working mode. At this time, you can continue to sample the indoor temperature value, and record the indoor temperature value collected by the indoor temperature acquisition device within the set time. Then, according to the recorded indoor temperature value, and the set time, you can get the average indoor temperature value.

Of course, the air conditioner control in the embodiment of the present disclosure can perform automatic and continuous control after the current semiconductor components operate at the first operating gear. Therefore, the current set duration corresponds to the current average indoor temperature value. The set duration can be 1 minute, 5 minutes, 10 minutes, or 20 minutes, etc. In some embodiments, the current set duration can be zero. At this time, the current average indoor temperature value is obtained through the indoor temperature acquisition device. The collected real-time current indoor temperature value.

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.

In the process of periodic automatic continuous control, the current absolute average temperature difference can be determined according to the current absolute average temperature difference, as well as the operating parameters and status of the air conditioner compressor and semiconductor components in the previous control corresponding to the previous set duration. The current operating frequency of the air conditioner compressor matched with the temperature difference, and the current operating status of the current semiconductor components.

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, the obtained air conditioner The operating frequency of the compressor is determined as the current operating frequency, and the highest gear is determined as the current operating gear in the start-up operation state of the current semiconductor components; when the current absolute average temperature difference is less than the first set temperature value Next, if the obtained operating frequency of the air conditioner compressor is greater than or equal to the second set frequency, the frequency reduction process is performed on the air conditioner compressor, and the reduced operating frequency is determined as the current operating frequency, and the highest gear is set to It is determined as the current operating gear in the start-up operation state of the current semiconductor components; 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, determine the obtained operating frequency of the air conditioner compressor as the current operating frequency, and perform downshift processing on the current semiconductor components, and determine the reduced operating gear as the current operating state of the semiconductor components. Current operating gear.

That is to say, when the previous operating gear of the current semiconductor components is the highest gear, the current absolute average temperature difference is relatively small, and the cooling capacity or heating capacity of the air conditioner can be reduced by downgrading or downshifting. The operation of semiconductor components can increase the cooling capacity or heating capacity of the air conditioner, improve the cooling and heating efficiency, and reduce the power consumption of the air conditioner.

However, in some embodiments, the previous operating gear of the current semiconductor components is not the highest gear, and the current operating frequency of the air conditioner compressor matching the current absolute average temperature difference and the current operating status of the current semiconductor components are determined It 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 conditioner compressor as the current operating frequency, and performing upshift processing on the current semiconductor components , determine the increased operating gear as the current operating gear in the current start-up operation state of the semiconductor components; 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, determine the obtained operating frequency of the air conditioner compressor as the current operating frequency, and determine the previous operating gear as the current operating gear in the current start-up operating state of the semiconductor components; in the current absolute When the average temperature difference is less than the first set temperature value, according to the start-up adjustment strategy, determine the current operating frequency of the air conditioner compressor, and perform downshift processing on the current semiconductor components, and determine the reduced operating gear as the current The current operating gear in the start-up operating state of the semiconductor component.

That is, when the previous operating gear of the current semiconductor components is not the highest gear, and the current absolute average temperature difference is large, an upshift can be performed to increase the cooling or heating capacity of the semiconductor components. When the current absolute average temperature difference is large, it is not necessary to adjust the operating parameters of the air conditioner compressor and semiconductor components; and when the current absolute average temperature difference is small, downshift processing can be performed. The operation of components can increase the cooling capacity or heating capacity of the air conditioner, improve the cooling and heating efficiency, and reduce the power consumption of the air conditioner.

Of course, when the last operating gear is the lowest gear, if the current absolute average temperature difference is less than the first set temperature value, downshifting processing is required, then the shut down and shutdown state can be determined as the current temperature of the current semiconductor components. Operating status.

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

After the current operating frequency of the air conditioner compressor matching the current absolute average temperature difference and the current operating state of the current semiconductor components are determined, the air conditioner compressor can be controlled to operate at the current operating frequency, and the current semiconductor components can be controlled to The current running state is running.

For example: the first set temperature value is 1.5°C, and the second set temperature value is 4.5°C, then the last operating gear of the current semiconductor component is the highest gear, that is, the third gear, if│Trp-Tset │When ≥ 1.5°C, the operating status of the air conditioner compressor and the current semiconductor components can be kept unchanged, and the operating frequency of the air conditioner compressor can still be controlled. During the operating time of the set operating cycle of the semiconductor components, the current Semiconductor components operate in third gear. Certainly, during the stop time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to be in a shutdown state. If│Trp-Tset│<1.5℃, at this time, it is necessary to obtain the running frequency of the air conditioner compressor. If the obtained operating frequency of the air conditioner compressor is greater than or equal to the second set frequency, it indicates that the high frequency of the air conditioner compressor Running, because Trp is already relatively close to Tset, at this time, the frequency reduction process can be performed on the air conditioner compressor, for example, the frequency reduction can be performed at a rate of 1HZ/1min, and the air conditioner compressor can be controlled to run at the reduced operating frequency, still The highest gear can be determined as the current operating gear in the start-up operation state of the current semiconductor component, that is, within the running time of the set operating cycle of the semiconductor component, control the current semiconductor component to still run in the third gear . If the acquired operating frequency of the air conditioner compressor is lower than the second set frequency, the frequency of the compressor 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, Control the current semiconductor components to run in the second gear.

When the last operating gear of the current semiconductor components is not the highest gear, that is, it may be the second gear or the first gear, if │Trp-Tset │≥4.5℃, the current absolute average temperature difference is a bit large, It is necessary to increase the cooling capacity or heating capacity of the air conditioner. Therefore, it is necessary to perform upshift processing, that is, to keep the operating frequency of the air conditioner compressor unchanged, and to perform upshift processing on the current semiconductor components, that is, to operate at the set operating frequency of the semiconductor components. During the running time of the cycle, control the current semiconductor components to run at the raised operating gear, that is, the previous operating gear is the second gear, and then it can be raised to the third gear for operation, and the previous operating gear If it is the first gear, it can be raised to the second gear for operation. If 1.5°C≤│Trp-Tset│<4.5°C, the running status of the air conditioner compressor and the current semiconductor can be kept unchanged. If │Trp-Tset│<1.5℃, it indicates that the current absolute average temperature difference is very small, and the air conditioner compressor maintains the start-up adjustment strategy of the air conditioner start-up configuration, that is, controls the operation of the air conditioner compressor according to the start-up adjustment strategy, In addition, downshifting processing is required, that is, within the operating time of the set operating cycle of the semiconductor component, the current semiconductor component is controlled to operate at a reduced gear.

Wherein, if the last operating gear is the lowest gear, for example, the first gear, when performing downshift processing, that is, when │Trp-Tset│<1.5°C, the current semiconductor components can be controlled to be in shutdown state.

The semiconductor components of the air conditioner may be equipped with a corresponding exhaust fan. The exhaust fan can enhance the air circulation and enhance the heat exchange between the two ends of the semiconductor components and the indoor/outdoor side, so as to realize the compensation of the cooling capacity/heating capacity of the system. Therefore, in some embodiments, when the current semiconductor component is in the start-up state, the operation of the corresponding exhaust fan on the current semiconductor component can also be controlled according to the current working mode.

Wherein, when the first semiconductor component is in the starting operation state, control the operation of the first exhaust fan and the second exhaust fan configured on the first semiconductor component; when the second semiconductor component is in the starting operation state Next, control the operation of the third exhaust fan and the fourth exhaust fan arranged on the second semiconductor component. Wherein, 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 heating end. Second, on the refrigeration end.

The semiconductor components stop running. In order to further reduce energy consumption, the corresponding exhaust fans can also be turned off. In some embodiments, when the current semiconductor components are in the shutdown state, control the corresponding The exhaust fan is switched 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; The third exhaust fan and the fourth exhaust fan configured on the second semiconductor component stopped running.

Moreover, when the semiconductor components of the air conditioner are turned off, the air conditioner can still use a vapor compression refrigeration cycle to adjust the indoor temperature.

At present, the air conditioner has a communication function, so that the air conditioner can also control the operation of semiconductor components according to the received instructions. In some embodiments, in the case of receiving the semiconductor switch instruction sent by the configuration control application APP terminal, the switching operation of the semiconductor components in the air conditioner is controlled according to the semiconductor switch instruction. In this way, the user can control the switching of semiconductor components through the APP, which improves the intelligence and user experience of the air conditioner.

Turn on the air conditioner to start the heating mode. In this way, when the heating operation time of the air conditioner reaches 20 minutes, the first flower acquisition module 4100 can obtain the average operating frequency P of the air conditioner compressor within 20 minutes, and can record that it is running in the heating mode within 12 minutes. For the indoor temperature value of the air conditioner, the first average indoor temperature value Trp1 within 12 minutes is obtained, and based on the current average indoor temperature value Trp1 and the target indoor temperature value Tset, the current absolute average temperature difference │Trp1-Tset│ is obtained.

In addition, when the previously obtained operating gear is the third operating gear, if │Trp-Tset│≥2.5°C, the fourth determining unit 4510 in the second determining module 4500 can obtain the operating frequency of the air conditioner compressor, It is determined as the current operating frequency of the air conditioner compressor, and the third gear is determined as the current operating gear in the starting operation state of the second semiconductor component. And if │Trp-Tset│<2.5°C, but the obtained operating frequency P≥Pmax of the air-conditioning compressor is 80%, the fifth determination unit 4520 can perform frequency reduction processing on the air-conditioning compressor, and reduce the operating frequency of the air-conditioning compressor The frequency is determined as the current operating frequency of the air conditioner compressor, and the third gear is determined as the current operating gear in the start-up 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 less than 80% of Pmax, the sixth determination unit 4530 determines the obtained operating frequency of the air-conditioning compressor as the air-conditioning compressor The current operating frequency of the second semiconductor component is downshifted, and the second operating gear is determined as the current operating gear in the start-up operating state of the second semiconductor component.

When the acquired previous operating gear is not the third operating gear, if │Trp-Tset│≥5.5°C, the seventh determination unit 4540 can determine the acquired operating frequency of the air conditioner compressor as the current operating frequency of the air conditioner compressor frequency, and perform an upshift process on the second semiconductor component, and determine the raised operating gear as the current operating gear in the start-up operating state of the second semiconductor component. And if 2.5°C≦│Trp-Tset│<5.5°C, the eighth determination unit 4550 can determine the obtained operating frequency of the air conditioner compressor as the current operating frequency, and determine the previous operating gear as the second The current operating gear in the start-up operating state of the semiconductor component. When │Trp-Tset│<2.5°C, the ninth determination unit 4560 determines the current operating frequency of the air conditioner compressor according to the start-up adjustment strategy, and performs downshift processing on the second semiconductor component to determine the reduced operating gear is the current operating gear in the start-up operating state of the second semiconductor component. Wherein, if the previous operating gear is the lowest gear, when downshifting the second semiconductor component, the ninth determination unit 4560 determines the shutdown state as the current operating state of the second semiconductor component.

Therefore, the second control module 4600 can control the air conditioner 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 gas on the first heating terminal of the second semiconductor component The fan is running, and the second exhaust fan on the first heating side is running. And, when the running time of the set running cycle of the semiconductor component reaches 15 minutes, the second control module 4600 can control the second semiconductor component to be in the shutdown state, and control the second heating terminal of the second semiconductor component The third exhaust fan on the heating end is turned off, and the fourth exhaust fan on the second heating end is turned off. And save the current running gear as the previous running gear.

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 conditioner control runs in the current working mode of the air conditioner and reaches the set start time, and the air conditioner compressor keeps running at a relatively high frequency, if 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 status of the air conditioner compressor and semiconductor components can be adjusted, so that the air conditioner can be improved by controlling the operation of the semiconductor components. The cooling capacity or heating capacity improves the cooling and heating efficiency, and the semiconductor components are controlled only when certain conditions are met, reducing the power consumption of the air conditioner.
