In the embodiment of the disclosure, two groups of semiconductor components are added in the air conditioner, and each group of semiconductor components is respectively connected with the air conditioner inner unit and the air conditioner outer unit, so that the refrigerating capacity or heating capacity of the air conditioner can be improved by controlling the operation of the semiconductor components, the refrigerating and heating requirements under severe working conditions are met, and the refrigerating and heating efficiency of the air conditioner is also improved.
Fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the air conditioner includes: the air conditioner indoor unit 100, the air conditioner outdoor unit 200, and the two sets of semiconductor components are a first semiconductor component 310 and a second semiconductor component 320, respectively.
The first cooling end 311 of the first semiconductor component 310 is connected to the air conditioner indoor unit 100, and the first heating end 312 of the first semiconductor component 310 is connected to the air conditioner outdoor unit 200.
The second cooling end 321 of the second semiconductor component 320 is connected to the air conditioner external unit 200, and the second heating end 322 of the second semiconductor component 320 is connected to the air conditioner internal unit 100.
In the embodiment of the disclosure, the semiconductor component can utilize the thermoelectric effect of the semiconductor, and the conductor is used for connecting two metals with different physical properties and is connected with direct current, so that the temperature at one end is reduced, the temperature at one end is increased, and the semiconductor component is commonly used for cooling electronic elements and miniature heat exchangers. A plurality of groups of hot spot elements exist in the semiconductor component, and the refrigerating and heating effects of the hot end at 40-50 ℃, the cold end at-10-20 ℃ and the temperature difference at 60 ℃ can be realized.
After the first semiconductor component 310 is turned on, a plurality of sets of hot spot elements are disposed in the first cooling end 311, so as to reduce the temperature, and a plurality of sets of hot spot elements are disposed in the first heating end 312, so as to increase the temperature. After the second semiconductor component 320 is turned on, the two ends can also respectively realize temperature reduction and temperature increase, wherein, a plurality of groups of hot spot elements are arranged in the second cooling end 321, so that the temperature reduction can be realized, and a plurality of groups of hot spot elements are also arranged in the second heating end 322, so that the temperature increase can be realized.
In some embodiments, the first semiconductor component 310 and the second semiconductor component 320 may cooperate with an indoor evaporator and an outdoor condenser of an air conditioner to pre-cool and pre-heat the evaporator inlet line and the condenser inlet line, respectively. As shown in fig. 1, one end of the first refrigerating end 311 is connected to the evaporator of the air conditioner indoor unit 100 through the indoor connection 110, the other end is connected to one end of the first heating end 312 through the first semiconductor component connection pipe 313, and the other end of the first heating end 312 is connected to the condenser of the air conditioner outdoor unit 200 through the outdoor connection 210.
One end of the second heating end 322 is connected with the evaporator of the air conditioner indoor unit 100 through the indoor connecting piece 110, the other end is connected with one end of the second cooling end 321 through the second semiconductor component connecting pipe 323, and the other end of the second cooling end 321 is connected with the condenser of the air conditioner outdoor unit 200 through the outdoor connecting piece 210.
It can be seen that the first semiconductor component and the second semiconductor component are arranged at opposite ends, and opposite temperature changes can be realized after the operation is started. When the refrigerating device is used for refrigerating, the first semiconductor component is started, so that the inlet pipeline of the evaporator in the air conditioner inner unit can be precooled, and the inlet pipeline of the condenser in the air conditioner outer unit can be preheated, so that indoor pre-cooling measurement and outdoor side preheating are realized; when heating, the second semiconductor component is started, an evaporator inlet pipeline in the air conditioner inner unit can be preheated, and a condenser inlet pipeline in the air conditioner outer unit is precooled, so that indoor preheating and outdoor precooling are realized, indoor refrigerating capacity can be improved at an external high temperature, indoor heating capacity is improved at an external low temperature, and the refrigerating and heating requirements under severe working conditions are met.
In some embodiments, exhaust fans for enhancing air circulation can be arranged at two ends of the two groups of semiconductor components, so that heat exchange between the two ends of the semiconductor components and indoor/outdoor sides can be enhanced, and compensation of refrigerating capacity/heating capacity of the system is realized. As shown in fig. 1, the air conditioner may further include: four exhaust fans; wherein, the first exhaust fan is located 410 on the first refrigeration side 311, the second exhaust fan 420 is located on the first heating side 312, the third exhaust fan 430 is located on the second heating side 322, and the fourth exhaust fan 440 is located on the second refrigeration side 321.
Of course, in some embodiments, the air conditioner may also have only one, two or three exhaust fans, and may be located at any end of any semiconductor component.
After the air conditioner is provided with two groups of semiconductor components or two groups of semiconductor components and the exhaust fans corresponding to the semiconductor components, the refrigerating capacity or heating capacity of the air conditioner can be improved by controlling the operation of the semiconductor components, so that the refrigerating and heating requirements under severe working conditions are met, and the refrigerating and heating efficiency of the air conditioner is also improved.
In the embodiment of the disclosure, when the air conditioner is started and the current working mode is operated to reach the set starting time and the air conditioner compressor is operated 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, the operating parameters and states of the air conditioner compressor and the semiconductor components can be adjusted, namely, the indoor temperature is far away from the target temperature value, and after the air conditioner is operated at high frequency for a long time, the semiconductor components can be started to provide supplementary cooling capacity or heat for the system, so that the power of the air conditioner is flexibly controlled, and the refrigerating capacity or the heating capacity of the air conditioner is improved by controlling the operation of the semiconductor components, so that the refrigerating and heating efficiency is improved and the power consumption of the air conditioner is reduced.
Fig. 2 is a schematic flow chart of a method for controlling an air conditioner according to an embodiment of the present disclosure. The air conditioner can be configured with two groups of semiconductor components or two groups of semiconductor components and corresponding exhaust fans. As shown in fig. 2, the process for air conditioning control includes:
step 2001: under the condition that the running time of the air conditioner running in the current working mode reaches the set starting time, acquiring the average running frequency of the air conditioner compressor in the set starting time, acquiring a first average indoor temperature value of the air conditioner running in the current working mode in a first set duration, and acquiring a first absolute average temperature difference value between the first average indoor temperature value and a target indoor temperature value.
In the embodiment of the disclosure, the air conditioner is started to operate in the current working mode, and at this time, vapor compression type operation can be adopted, namely, the operation of the air conditioner compressor is controlled according to the collected indoor and outdoor temperature values. The current operating mode may include: cooling, heating, dehumidifying and the like. The set starting time can be preset, and after the set starting time is reached after the air conditioner is started and operated, the working state of the air conditioner is relatively stable, so that the set starting time can be determined according to the performance parameters of the air conditioner and can be 15, 20, 25, 30 minutes and the like.
If the running time of the air conditioner in the current working mode reaches the set starting time, for example: and running for 20 minutes, wherein the air conditioner is in a stable running state, and the average running frequency Pp of the air conditioner compressor in the set starting time can be obtained, at this time, a first average indoor temperature value of the air conditioner running in the current working mode in a first set duration can be obtained, and a first absolute average temperature difference value between the first average indoor temperature value and the target indoor temperature value is obtained.
In the embodiment of the disclosure, the area where the air conditioner is located may be configured with an indoor temperature acquisition device, so that after the air conditioner reaches the set starting time, according to the recorded first set duration, the first average indoor temperature value Trp1 can be obtained by the indoor temperature acquired by the indoor temperature acquisition device. The first set duration may be 3, 5, 8, or 10 minutes, or may be zero, that is, the first average indoor temperature value may be the obtained instant indoor temperature value.
The first average indoor temperature value Trp1 is obtained, and a first absolute average temperature difference value |trp1-tset| between the first average indoor temperature value Trp1 and the target indoor temperature value Tset is obtained.
Step 2002: and determining a first operating frequency of the air-conditioning compressor matched with the average operating frequency and a first operating state of the current semiconductor component when the first absolute average temperature difference value is larger than or equal to the second set temperature value, wherein the current semiconductor component is matched with the current working mode.
Generally, when an air conditioner is operated in modes of cooling, heating, dehumidifying and the like, the larger the first absolute average temperature difference value is, the larger the required cooling capacity or heating capacity is, and at this time, the semiconductor components need to be started to operate. And when the first absolute average temperature difference value is smaller, the air conditioner compressor can be kept running in the existing state. Thus, a second set temperature value, which is a little larger, may be preset, for example: 4.5 ℃, 5 ℃ or 6 ℃ and the like, thus, under the condition that the first absolute average temperature difference value is larger than or equal to the second set temperature value, the operation parameters and states of the air conditioner compressor and the semiconductor components are required to be adjusted according to the average operation frequency of the air conditioner compressor in the set starting time, and the refrigerating capacity or the heating capacity of the air conditioner is improved by controlling the operation of the semiconductor components, and the refrigerating and heating efficiency is improved.
Because the first refrigerating end of the first semiconductor component is connected with the air conditioner indoor unit, the first heating end of the first semiconductor component is connected with the air conditioner outdoor unit, and thus, after the first semiconductor component starts to operate, indoor pre-cooling and outdoor side preheating can be realized; the second refrigerating end of the second semiconductor component is connected with the air conditioner external unit, and the second heating end of the second semiconductor component is connected with the air conditioner internal unit, so that after the second semiconductor component starts to operate, the indoor preheating measurement and the outdoor precooling can be realized.
It can be seen that the current semiconductor component matched with the current operation mode can be determined according to the connection relation of the first semiconductor component and the second semiconductor component. When the current working mode is a refrigeration mode, the current semiconductor component is a first semiconductor component; when the front working mode is a heating mode, the front semiconductor component is a 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 operation parameters and states of the air conditioner compressor and the semiconductor components may be adjusted according to the average operation frequency of the air conditioner compressor within the set start time, that is, the first operation frequency of the air conditioner compressor matched with the average operation frequency and the first operation state of the current semiconductor components may be determined, which may specifically include: under the condition that the average operating frequency is smaller than the first set frequency, the air conditioner compressor is subjected to frequency raising treatment, the raised operating frequency is determined to be the first operating frequency, and the closed shutdown state is determined to be the first operating state of the current semiconductor component; under the condition that the average operating frequency is larger than or equal to the first set frequency and smaller than the second set frequency, determining the first operating frequency of the air conditioner compressor according to a starting adjustment strategy, and determining a starting operating state as a first operating state of the current semiconductor component; and under the condition that the average operating frequency is greater than or equal to the second set frequency, determining the acquired operating frequency of the air conditioner compressor as a first operating frequency, and determining the starting operating state as a first operating state of the current semiconductor component.
Thus, when the air conditioner starts to run and reaches the set starting 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 value-Trp 1-Tset-is equal to or greater than 5.5 ℃, the indoor temperature difference is relatively large, and at this time, the operation parameters and states of the air conditioner compressor and the semiconductor components need to be adjusted according to the average operation frequency.
Wherein, a first set frequency and a second set frequency can be preset, wherein, the second set frequency can be larger than the first set frequency, for example: the first set frequency may be 45%, 50%, or 55%, etc. of the maximum operating frequency of the air conditioner compressor, and the second set frequency may be 70%, 80%, 85%, or 90%, etc. of the maximum operating frequency of the air conditioner compressor. Therefore, when the average operating frequency is smaller than the first set frequency, the operating frequency of the air conditioner compressor is not large, and the operating frequency of the air conditioner compressor can be increased through the frequency raising treatment, so that the refrigerating capacity or heating capacity of the air conditioner is improved, namely, at the moment, a semiconductor component is not required to be started, and the refrigerating capacity or heating capacity of the air conditioner is only required to be adjusted by adjusting the operating frequency of the air conditioner compressor, so that the efficiency of the air conditioner is improved. Therefore, the shut down state may be determined to be the first operating state of the current semiconductor component, and the air conditioner compressor may need to be frequency up-converted, and the frequency up-converted may be determined to be the first operating frequency.
If the average operating frequency is greater than or equal to the first set frequency, the air conditioner keeps running at a higher frequency in the set starting time, but the indoor temperature value still does not reach the target indoor temperature value, at this time, the semiconductor component is required to be started for auxiliary refrigeration or heating, namely, the refrigerating capacity or heating capacity of the air conditioner is adjusted by starting the semiconductor component, so that the efficiency of the air conditioner is improved, and the starting operating state can be determined to be the first operating state of the current semiconductor component. In some embodiments, the operation frequency of the compressor can be further adjusted to adjust the refrigerating capacity or heating capacity of the air conditioner. 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, and at this time, the operating frequency of the compressor can be adjusted according to a 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 operated at a high frequency, so that the operating frequency of the air conditioner is maintained unchanged, namely, the acquired operating frequency of the air conditioner compressor is determined as the first operating frequency.
For example, in the case of the air-conditioning cooling mode operation, if the first absolute average temperature difference is greater than or equal to the second set temperature value, for example, when the value of Trp1-Tset I is equal to or greater than 5 ℃, the operation parameters and states of the air-conditioning compressor and the semiconductor components can be adjusted according to the average operation frequency of the air-conditioning compressor within the set start time. 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 a starting operating state, so that after the first semiconductor component is started to operate, the evaporator inlet pipeline in the air conditioner inner unit can be precooled, and the condenser inlet pipeline in the air conditioner outer unit can be preheated, thereby improving the refrigerating capacity of the air conditioner, and further improving the refrigerating efficiency of the air conditioner. And under the condition of air conditioner heating mode operation, if the first absolute average temperature difference value is larger than or equal to the second set temperature value, for example, trp1-Tset I is larger than or equal to 5 ℃, wherein if the average operation frequency Pp is larger than or equal to the first set frequency, the first operation state of the second semiconductor component is determined to be a starting operation state, so that after the second semiconductor component is started to operate, an evaporator inlet pipeline in an air conditioner inner unit can be preheated, and a condenser inlet pipeline in an air conditioner outer unit is precooled, thereby improving the heating capacity of the air conditioner, and further improving the heating efficiency of the air conditioner.
Step 2003: the air conditioner compressor is controlled to operate at a first operating frequency, and the current semiconductor component is controlled to operate at a first operating state.
After the first operating frequency of the air conditioner compressor and the first operating state of the current semiconductor component are determined, the air conditioner compressor can be controlled to operate at the first operating frequency, and the current semiconductor component is 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, and controlling the air conditioner compressor to operate at the first operating frequency may include: and if the average operating frequency is smaller than the first set frequency, performing frequency-raising treatment on the air conditioner compressor, and controlling the air conditioner compressor to operate at the raised operating frequency. If the average running 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 starting adjustment strategy, and the air-conditioning compressor is controlled to run at the adjusted running frequency. If the average operating frequency is greater than or equal to the second set frequency, the air conditioner compressor is controlled to operate at the constant operating 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 component can be controlled to be in a starting operating state all the time, however, the semiconductor component is limited by materials, long-term continuous operation can result in reduced reliability of the component, and long-term operation of the semiconductor can also increase 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 of the current semiconductor component in the air conditioner in the start-up operating state may be 5, 8, 10, 15min, or the like.
Alternatively, in some embodiments, the semiconductor component does not continue to operate for a long period of time, the operation period may be set to be a unit operation, and the semiconductor component is operated for a period of time during the set operation period, and the semiconductor component is stopped for the remaining period of time, i.e., the set operation period includes: run time and stop time. For example: the set operation period can be 20min, so that the semiconductor component can be operated according to the mode of stopping for 10min after 10min in the periodic operation process, and at the moment, the operation time and the stop time are both 10min. Or, the set operation period may be 30min, so that the semiconductor component may be operated in a mode of stopping for 10min after 20min in the periodic operation process, and the operation time is 20min and the stop time is 10min.
Thus, in the present embodiment, controlling the current semiconductor component to operate in the first operating state may include: the current semiconductor component matched with the current operation mode is controlled to operate for one period in the first operation state. The method specifically comprises the following steps: when the first absolute average temperature difference value is larger than or equal to the second set temperature value and the average operating frequency is larger than or equal to the first set frequency, controlling the current semiconductor component to be in a starting operating state in the operating time of the set operating period of the semiconductor component; and controlling the current semiconductor component to be in a closing and stopping state in the stopping time of the set running period of the semiconductor component. For example: when Trp1-Tset I is not less than 4.5 ℃ and the average operating frequency Pp is not less than 50% of the maximum operating frequency Pmax, the current semiconductor component is controlled to be in a starting operating state within 10min of the set operating period of the semiconductor component within 20min, and then the current semiconductor component can be controlled to be in a closing and stopping state. The current semiconductor components can be turned off after being started to operate for 10min, so that the refrigerating capacity or heating capacity of the air conditioner is improved by controlling the operation of the semiconductor components, the refrigerating and heating efficiency is improved, and the power consumption of the air conditioner is reduced.
Of course, in some embodiments, the semiconductor may perform periodic operation, but the current semiconductor component may not be periodically controlled, that is, the time of the air conditioner in the start-up operation state of the current semiconductor component may not be the operation time of the set operation period, which is not specifically exemplified.
In the embodiment of the disclosure, the power of the semiconductor component is adjustable, and the corresponding output cold or heat is different, so that the semiconductor component can output different cold or heat according to different control input currents under the same control input voltage. In some embodiments, the semiconductor components correspond to two or more operating ranges, and the greater the control input current to the semiconductor components, the higher the corresponding operating range, and the more output energy. For example: the control input voltage is 220V, and the control input currents are 0.5A, 1A and 1.5A respectively, so that the semiconductor component corresponds to three gears of low, medium and high. Of course, the semiconductor component may correspond to only two low and high gears, and so on.
It can be seen that in some embodiments, when the current semiconductor component is in the start-up operating state, different operating gears may be corresponding, and thus controlling the current semiconductor component to operate in the first operating state includes: determining a first operating gear of the current semiconductor component corresponding to the average operating frequency under the condition that the average operating frequency is greater than or equal to a first set frequency; and controlling the current semiconductor component to operate in the first operation gear within the operation time of the set operation period of the semiconductor component. The semiconductor component corresponds to two or more operation gears, and the larger the control input current of the semiconductor component is, the higher the corresponding operation gears are. Of course, the current semiconductor component can be controlled to be in a closed and stopped state within the stop time of the set operation period of the semiconductor component.
Wherein determining the first operating range of the current semiconductor component corresponding to the average operating frequency comprises: under the condition that the average operating frequency is larger than or equal to the first set frequency and smaller than the second set frequency, determining the second gear as the first operating gear of the current semiconductor component; and determining the third gear as the first operation gear of the current semiconductor component under the condition that the average operation frequency is greater than or equal to the second set frequency. The control input current of the semiconductor component corresponding to the third gear is larger 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 larger than the control input current of the semiconductor component corresponding to the first gear.
For example: the second set temperature value is 4 ℃, the first set frequency is 40% of the highest frequency Pmax, and the second set frequency is 65% of the highest frequency Pmax. Thus, if Pmax is 40% or less and the average operating frequency Pp is less than 65% of Pmax under the condition that the value of Trp1-Tset I is equal to or greater than 4 ℃, the second gear can be determined to be the first operating gear of the current semiconductor component; and if 65% of Pmax is less than or equal to Pp, determining that the third gear is the first operation gear of the current semiconductor component.
Of course, the semiconductor components correspond to two, four, five, etc. operating gears, and the corresponding first operating gear of the current semiconductor component may 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 operate in the first operating gear, or the current semiconductor component can be controlled to operate in the first operating gear within a set time period. In some embodiments, the current semiconductor component may be controlled to operate in the first operating range during an operating time of a set operating cycle of the semiconductor component.
Therefore, in the embodiment of the disclosure, when the air conditioner starts the current working mode to run for a set starting time and the air conditioner compressor keeps running at a higher frequency, if the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value is still larger, the running parameters and states of the air conditioner compressor and the semiconductor components can be adjusted, so that the refrigerating capacity or heating capacity of the air conditioner is improved by controlling the running of the semiconductor components, the refrigerating and heating efficiency is improved, and the semiconductor components are controlled only when certain conditions are met, so that the power consumption of the air conditioner is reduced. And different average operating frequencies of the compressors correspond to different operating gears of the semiconductor components, namely, correspond to different output energies of the semiconductor components, so that the refrigerating or heating efficiency of the air conditioner is further improved.
When the running time of the air conditioner running in the current working mode reaches the set starting time and the running time of the set running period of the semiconductor component is controlled to run in the first running gear, the air conditioner can be continuously controlled to run in the vapor compression mode, and the semiconductor component is not controlled to run any more. However, in order to improve the temperature adjustment efficiency of the air conditioner, in some embodiments, after controlling the current semiconductor component to operate in the first operation gear, the operation of the current semiconductor component and the operation of the air conditioner compressor may be periodically controlled according to the obtained current average indoor temperature value in the current set time period, which may include: under the condition that the current semiconductor component is in a closed and stopped state and the duration time of the air conditioner in the current mode running state reaches the preset sampling duration time, acquiring a current average indoor temperature value in the current set duration time of the area where the air conditioner is located, and acquiring a current absolute average temperature difference value between the current average indoor temperature value and a target indoor temperature value; determining the current operating frequency of the air conditioner compressor matched with the current absolute average temperature difference value and the current operating state of the current semiconductor component; the air conditioner compressor is controlled to operate at the current operating frequency, and the current semiconductor components are controlled to operate at the current operating state.
And controlling the current semiconductor component to be in a closed shutdown state after the current semiconductor component is controlled to run in a first running gear within the running time of the set running period of the semiconductor component, wherein the air conditioner is run in a current mode, the preset sampling time can be 5, 10, 15, 25 minutes and the like under the condition that the duration time of the running state of the air conditioner in the current mode reaches the preset sampling time, namely, the semiconductor component is not started to run all the time within the preset sampling time, is in the closed shutdown state, and the air conditioner is also run in the current working mode all the time, at the moment, the indoor temperature value can be continuously sampled, the indoor temperature value acquired by the indoor temperature acquisition device within the set time is recorded, and then the average indoor temperature value can be obtained according to the recorded indoor temperature value and the set time.
Of course, after the current semiconductor component is controlled to operate in the first operation gear by the air conditioner in the embodiment of the disclosure, automatic continuous control can be performed, so that the current set duration corresponds to the current average indoor temperature value. The set duration may be 1 minute, 5 minutes, 10 minutes, 20 minutes, or the like, and in some embodiments, the current set duration may be zero, where the current average indoor temperature value is a real-time current indoor temperature value acquired by the indoor temperature acquisition device.
The current average indoor temperature value Trp is obtained, and the current absolute average temperature difference value |trp-tset| between the current average indoor temperature value Trp and the target indoor temperature value Tset is obtained.
In the process of periodic automatic continuous control, the current running frequency of the air conditioner compressor matched with the current absolute average temperature difference and the current running state of the current semiconductor component can be determined according to the current absolute average temperature difference and the running parameters and states of the air conditioner compressor and the semiconductor component in the previous control corresponding to the previous set time length.
In some embodiments, when the previous operating gear of the front semiconductor component is the highest gear, it may include: under the condition that the current absolute average temperature difference value is larger than or equal to a first set temperature value, determining the acquired 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; if the current absolute average temperature difference value is smaller than the first set temperature value, performing frequency reduction processing on the air conditioner compressor if the acquired operating frequency of the air conditioner compressor is larger than or equal to the second set frequency, 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; and under the condition that the current absolute average temperature difference value is smaller than the first set temperature value, if the acquired operating frequency of the air-conditioning compressor is smaller than the second set frequency, determining the acquired operating frequency of the air-conditioning compressor as the current operating frequency, performing downshift processing on the current semiconductor component, and determining the lowered operating gear as the current operating gear in the starting operating state of the current semiconductor component.
That is, when the previous running gear of the semiconductor component is the highest gear, the current absolute average temperature difference is relatively small, the refrigerating capacity or heating capacity of the air conditioner can be reduced in a down-conversion or down-shift mode, the refrigerating capacity or heating capacity of the air conditioner is improved by controlling the running of the semiconductor component, the refrigerating and heating efficiency is improved, and meanwhile the power consumption of the air conditioner is reduced.
In some embodiments, the previous operating gear of the current semiconductor device is not the highest gear, determining the current operating frequency of the air conditioner compressor that matches the current absolute average temperature difference value, and the current operating state of the current semiconductor device may include: under the condition that the current absolute average temperature difference value is larger than or equal to a second set temperature value, determining the acquired operating frequency of the air conditioner compressor as the current operating frequency, performing upshift processing on the current semiconductor component, and determining the upshift operating gear as the current operating gear in the starting operating state of the current semiconductor component; when the current absolute average temperature difference value is smaller than the second set temperature value and is larger than or equal to the first set temperature value, determining the acquired operating frequency of the air conditioner 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; and under the condition that the current absolute average temperature difference value is smaller than the first set temperature value, determining the current operating frequency of the air conditioner compressor according to a starting adjustment strategy, performing downshift processing on the current semiconductor component, and determining the lowered operating gear as the current operating gear in the starting operating state of the current semiconductor component.
That is, when the previous running gear of the semiconductor component is not the highest gear, the upshift process can be performed when the current absolute average temperature difference is large, so that the refrigerating capacity or heating capacity of the semiconductor component is improved. When the current absolute average temperature difference is larger, the operation parameters of the air conditioner compressor and the semiconductor components can not be adjusted; and when the current absolute average temperature difference value is smaller, the downshift treatment can be performed, so that the refrigerating capacity or heating capacity of the air conditioner is improved by controlling the operation of the compressor and the semiconductor components, the refrigerating and heating efficiency is improved, and the power consumption of the air conditioner is reduced.
Of course, when the previous operating gear is the lowest gear, if the current absolute average temperature difference is smaller than the first set temperature value and the downshift is required, the shutdown state can be determined as the current operating state of the current semiconductor component.
The first set temperature value is smaller than the second set temperature value, and can be determined according to the position of the air conditioner and the performance of the air conditioner.
After the current running frequency of the air conditioner compressor matched with the current absolute average temperature difference value and the current running state of the current semiconductor component are determined, the air conditioner compressor can be controlled to run at the current running frequency, and the current semiconductor component is controlled to run at the current running state.
For example: the first set temperature value is 1.5 ℃, the second set temperature value is 4.5 ℃, the previous running gear of the current semiconductor component is the highest gear, namely, when in the third gear, if the value of Trp-Tset is more than or equal to 1.5 ℃, the running states of the air conditioner compressor and the current semiconductor component can be kept unchanged, the running frequency of the air conditioner compressor is still controlled to be unchanged, and the current semiconductor component is controlled to run in the third gear in the running time of the set running period of the semiconductor component. Of course, the current semiconductor component is controlled to be in a closed and stopped state within the stop time of the set operation period of the semiconductor component. If the temperature of the air-conditioning compressor is equal to or lower than the first set frequency, the air-conditioning compressor is required to be operated at the temperature of-Tset <1.5 ℃, and if the obtained operating frequency of the air-conditioning compressor is higher than or equal to the second set frequency, the air-conditioning compressor is indicated to be operated at a high frequency, because Trp is relatively close to Tset, at this time, the air-conditioning compressor can be subjected to frequency reduction processing, for example, frequency reduction can be performed at a rate of 1HZ/1min, and the air-conditioning compressor is controlled to operate at the reduced operating frequency, and the highest gear can still be determined as the current operating gear in the starting operating state of the current semiconductor component, namely, the current semiconductor component is controlled to still operate at the third gear in the operating time of the set operating period of the semiconductor component. If the obtained operation frequency of the air conditioner compressor is smaller than the second set frequency, the compressor frequency is not adjusted, the current semiconductor component is required to be subjected to the downshift treatment, and the current semiconductor component is controlled to operate in the second gear within the operation time of the set operation period of the semiconductor component.
When the previous running gear of the current semiconductor component is not the highest gear, namely the second gear or the first gear, if the absolute average temperature difference value is equal to or greater than or equal to 4.5 ℃ and the absolute average temperature difference value is a little larger, the refrigerating capacity or heating capacity of the air conditioner needs to be increased, so that upshift treatment is needed, namely the running frequency of the air conditioner compressor is kept unchanged, the current semiconductor component can be upshifted, namely the running of the current semiconductor component in the running time of the set running period of the semiconductor component is controlled, namely the running of the current semiconductor component in the raised running gear, namely the previous running gear is the second gear, the running of the current semiconductor component can be raised into the third gear, and the running of the current semiconductor component can be raised into the second gear. If the temperature is equal to or less than 1.5 ℃ and equal to or less than 4.5 ℃, the running state of the air conditioner compressor and the current semiconductor can be maintained unchanged. If Trp-Tset-1.5 deg.C, the absolute average temperature difference is very small, the air conditioner compressor maintains the start-up regulation strategy of the start-up configuration of the air conditioner to regulate, i.e. the operation of the air conditioner compressor is controlled according to the start-up regulation strategy, and the down shift treatment is needed, i.e. the current semiconductor component is controlled to operate in the reduced gear in the operation time of the set operation period of the semiconductor component.
If the previous operating gear is the lowest gear, for example, the first gear, the current semiconductor device can be controlled to be in a shutdown state when the downshift is performed, namely, when the temperature of the-Trp-Tset is <1.5 ℃.
The semiconductor components of the air conditioner may be provided with corresponding exhaust fans, the exhaust fans can strengthen air circulation, and heat exchange between two ends of the semiconductor components and indoor/outdoor sides is enhanced, so that compensation of refrigerating capacity/heating capacity of the system is realized. Therefore, in some embodiments, when the current semiconductor component is in the start-up operation state, the operation of the exhaust fan corresponding to the current semiconductor component can be controlled according to the current operation mode.
When the first semiconductor component is in a starting operation state, controlling a first exhaust fan and a second exhaust fan which are arranged on the first semiconductor component to operate; and controlling the third exhaust fan and the fourth exhaust fan which are arranged on the second semiconductor component to operate under the condition that the second semiconductor component is in a starting operation state. In the air conditioner, a first exhaust fan is positioned on a first refrigerating end, a second exhaust fan is positioned on a first heating end, a third exhaust fan is positioned on a second heating end, and a fourth exhaust fan is positioned on a second refrigerating end.
In some embodiments, when the current semiconductor component is in a shutdown state, the corresponding exhaust fan on the current semiconductor component is controlled to be turned off. Namely, under the condition that the first semiconductor component stops running, controlling a first exhaust fan and a second exhaust fan which are arranged on the first semiconductor component to stop running; and under the condition that the second semiconductor component stops operating, controlling a third exhaust fan and a fourth exhaust fan which are arranged on the second semiconductor component to stop operating.
And, under the condition that the semiconductor components of the air conditioner are in a closed and stopped state, the air conditioner can still adopt vapor compression refrigeration cycle to realize the regulation of indoor temperature.
Currently, air conditioners have a communication function, and thus, the air conditioner can also control the operation of semiconductor components according to received instructions. In some embodiments, under the condition that a semiconductor switching instruction sent by the configuration control Application (APP) terminal is received, the switching operation of semiconductor components in the air conditioner is controlled according to the semiconductor switching instruction. Like this, the switch of user accessible APP control semiconductor components has improved the intelligent and the user experience of air conditioner.

The following illustrates an air conditioning control process performed by the apparatus for air conditioning control provided in the embodiment of the present disclosure.
The air conditioner may include two sets of semiconductor components and four exhaust fans as shown in fig. 1. The first set temperature value stored in the air conditioner is 2.5 ℃, and the second set temperature value is 5.5 ℃. And, the semiconductor components correspond to 3 operation gears, and the output energy of third gear is greater than the output energy of second gear, and the output energy of second gear is greater than the output energy of first gear. The first set frequency is 50% of the highest frequency of the air conditioner compressor, and the second set frequency is 80% of the highest frequency of the air conditioner compressor. The set start time may be 20min, the set duration and the first set duration may be 12min, the set operation period of the semiconductor component may be 30min, and the operation time of the set operation period may be 15min; the set starting time can be the running time of the set running period and is also 15 minutes; the preset sampling duration may also be 15 minutes. The current operation mode of the air conditioner is a heating mode, and the corresponding second semiconductor component is a second semiconductor component.
Fig. 5 is a schematic structural view of an air conditioner control device according to an embodiment of the present disclosure. As shown in fig. 5, the control device for an air conditioner 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, wherein the first determination module 4200 comprises: the first determining unit 4210, the second determining unit 4220, and the third determining unit 4320, and the first control module 4300 includes: a first gear determination unit 4310 and a first control unit 4320. The second determination module 4500 includes: the third determination unit 4510, the fourth determination unit 4520, the sixth determination unit 4530, the seventh determination unit 4540, the eighth determination unit 4550, and the ninth determination unit 4560.
When the air conditioner is started to perform heating mode starting, and when the heating operation time of the air conditioner reaches 20min, the first flower acquisition module 4100 can acquire the average operation frequency P of the air conditioner compressor within 20min, and can record the indoor temperature value of the air conditioner in the heating mode operation within 12min, so as to obtain a first average indoor temperature value Trp1 within 12min, and according to the current average indoor temperature value Trp1 and the target indoor temperature value Tset, obtain a current absolute average temperature difference value Trp 1-Tset.
Thus, if Trp1-Tset <5.5 ℃, the air conditioner operates normally. If Trp1-Tset is equal to or greater than 5.5 ℃ and the average operating frequency Pp < 50% of Pmax, the first determination unit 4210 in the first determination module 4200 may perform an up-conversion process on the air conditioner compressor, and determine the up-converted operation frequency as the first operation frequency, and determining the shutdown state as the first operation state of the second semiconductor device, so that the first control module 4300 may perform the frequency up-conversion process on the air-conditioning compressor, control the air-conditioning compressor to operate at the increased operation frequency, and control the second semiconductor device to be in the shutdown state.
If Trp1-Tset I is equal to or higher than 5.5 ℃, pmax is equal to or higher than 50% Pp < 80% of Pmax, the second determining unit 4220 in the first determining module 4200 determines the first operating frequency of the air conditioner compressor according to the start-up adjustment strategy, determines the start-up operating state as the first operating state of the second semiconductor device, and the first gear determining unit 4310 in the first control module 4300 determines the second gear as the first operating gear of the second semiconductor device.
If Trp1-Tset I is equal to or higher than 5.5 ℃ and Pmax is 80% or lower than Pp, the third determining unit 4230 in the first determining module 4200 determines the obtained operation frequency of the air conditioner compressor as the first operation frequency, determines the start-up operation state as the first operation state of the second semiconductor device, and the first gear determining unit 4310 determines the third gear as the first operation gear of the second semiconductor device.
Thus, the first control unit 4320 in the first control module 4300 may control the air conditioning compressor to operate at a first operating frequency, the second semiconductor component to operate at a first operating gear, and the first exhaust fan on the first heating side of the second semiconductor component to operate. And when the operation time of the set operation period of the semiconductor components reaches 15min, the first control unit 4320 can control the second semiconductor components to be in a closed and stopped state, and control the third exhaust fan on the second heating end of the second semiconductor components to be closed, and control the fourth exhaust fan on the second heating end to be closed. And saves the first operating gear as the previous operating gear.
And after the second semiconductor component is controlled to operate in the first operation gear, the second semiconductor component can be continuously controlled. Under the condition that the second semiconductor component is in a closed and stopped state and the duration time of the air conditioner in the current mode running state reaches the preset sampling duration time 15min, the second obtaining module 4400 obtains a current average indoor temperature value Trp within a current set time 12min of an area where the air conditioner is located, and obtains a current absolute average temperature difference value l Trp-Tset l between the current average indoor temperature value and the target indoor temperature value.
And, if the previous operating gear is the third operating gear and the value of Trp-Tset is equal to or greater than 2.5 ℃, the fourth determining unit 4510 in the second determining module 4500 may determine the operating frequency of the air conditioner compressor, the method includes determining a current operating frequency of the air conditioner compressor, and determining a third gear as a current operating gear in a start-up operating state of the second semiconductor component. And if the l-Trp-Tset-is <2.5 deg.c, but the obtained operation frequency P of the air conditioner compressor is equal to or greater than 80% of Pmax, the fifth determining unit 4520 may perform the frequency down-conversion process on the air conditioner compressor, determine the reduced operation frequency as the current operation frequency of the air conditioner compressor, and determine the third gear as the current operation gear in the start-up operation state of the second semiconductor device. If the temperature of the air-conditioning compressor is equal to-Trp-Tset-is equal to <2.5 ℃, but the acquired operation frequency P of the air-conditioning compressor is equal to 80% of Pmax, the sixth determining unit 4530 determines the acquired operation frequency of the air-conditioning compressor as the current operation frequency of the air-conditioning compressor, performs the downshift process on the second semiconductor component, and determines the second operation gear as the current operation gear in the start-up operation state of the second semiconductor component.
When the obtained previous operation gear is not the third operation gear, if the l-Trp-Tset l is equal to or higher than 5.5 ℃, the seventh determining unit 4540 may determine the obtained operation frequency of the air-conditioning compressor as the current operation frequency of the air-conditioning compressor, perform the upshift process on the second semiconductor device, and determine the upshift operation gear as the current operation gear in the start-up operation state of the second semiconductor device. And if the temperature of the air-conditioning compressor is equal to or lower than 2.5 ℃ and equal to or lower than the temperature of the-Trp-Tset-is equal to or lower than 5.5 ℃, the eighth determining unit 4550 may determine the obtained operating frequency of the air-conditioning compressor as the current operating frequency and the previous operating gear as the current operating gear in the start-up operating state of the second semiconductor component. And when the temperature of the-Trp-Tset-is <2.5 ℃, the ninth determining unit 4560 determines the current operating frequency of the air conditioner compressor according to the start-up adjustment strategy, and performs a downshift process on the second semiconductor component, and determines the lowered operating gear as the current operating gear in the start-up operating state of the second semiconductor component. If the previous operating range is the lowest range, the ninth determining unit 4560 determines the shutdown state as the current operating state of the second semiconductor device when the downshift is performed on the second semiconductor device.
Thus, the second control module 4600 may control the air conditioning compressor to operate at a current operating frequency, the second semiconductor component to operate at a current operating gear, and the first exhaust fan on the first heating end of the second semiconductor component to operate, the second exhaust fan on the first heating end to operate. And when the operation time reaching the set operation period of the semiconductor components reaches 15min, the second control module 4600 can control the second semiconductor components to be in a closed and stopped state, and control the third exhaust fan on the second heating end of the second semiconductor components to be closed, and control the fourth exhaust fan on the second heating end to be closed. And saving the current running gear as the previous running gear.
Therefore, when the air conditioner is started in the current working mode and reaches the set starting time and the air conditioner compressor is kept to operate at a higher 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, so that the refrigerating capacity or heating capacity of the air conditioner is improved by controlling the operation of the semiconductor components, the refrigerating and heating efficiency is improved, and the semiconductor components are controlled only when certain conditions are met, and the power consumption of the air conditioner is reduced.
