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, in a set starting time, the air conditioner performs starting operation of a current working mode, the air conditioner compressor can be controlled to perform the current working mode operation at the highest frequency, and the current semiconductor component matched with the current working mode is controlled to be in a starting operation state, so that the semiconductor component which is operated for a period of time in the room can be maintained at a target indoor temperature value for a long time, the power consumption of the air conditioner is saved, the user experience is improved, and then the operation parameters and states of the air conditioner compressor and the semiconductor component can be adjusted according to the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value, thereby flexibly controlling the power of the air conditioner, improving the refrigerating capacity or heating capacity of the air conditioner by controlling the operation of the semiconductor component, improving the refrigerating and heating efficiency and reducing the power consumption of the air conditioner.
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 air conditioner starts the current working mode operation, controlling the air conditioner to start the operation, including: the air conditioner compressor operates in the current working mode at the highest frequency, and the current semiconductor component matched with the current working mode is in a starting operation state in the set starting time.
In the embodiment of the disclosure, when the air conditioner is started to operate, the air conditioner compressor needs to be firstly adjusted to the highest frequency and the semiconductor components are operated for a period of time, namely, the indoor temperature is quickly adjusted through the high-frequency operation of the compressor and the operation of the semiconductor components, so that the indoor temperature value is quickly close to a target indoor temperature value, indoor temperature balance can be ensured in a longer time, and the air conditioner efficiency and user experience are improved.
The current operating mode may include: cooling, heating, dehumidifying and the like. 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.
At present, semiconductor components are limited by materials, the reliability of parts is reduced due to long-term continuous operation, and the power consumption of an air conditioner is increased due to long-term operation of semiconductors. Therefore, the set start time corresponding to the start operation of the air conditioner may be 5, 8, 10, or 15 minutes, etc.
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. Therefore, in the present embodiment, the set start-up time may be the operation time of the set operation period. At this time, the control air conditioner starts the operation, including: the air conditioner compressor operates in the current working mode at the highest frequency, and controls the current semiconductor component matched with the current working mode to start up and operate for one period, namely, the current semiconductor component matched with the current working mode is in a starting up and operating state in the operating time of the set operating period of the semiconductor component. Of course, in some embodiments, the semiconductor may perform periodic operation, but when the air conditioner is started, the current semiconductor component may not be periodically controlled, that is, the set start time may not be the operation time of the set operation period, which is not specifically exemplified.
Step 2002: under the condition that the starting operation is completed, acquiring a current average indoor temperature value in a current set time period of an area where the air conditioner is operated in a current working mode, and acquiring a current absolute average temperature difference value between the current average indoor temperature value and a target indoor temperature value.
The air conditioner starts running and reaches the set starting time, the completion of the starting running of the air conditioner can be determined, and at the moment, the current semiconductor components can be controlled to be in a closed and stopped state. And, the air conditioner still operates the current working mode.
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 start operation of the air conditioner is completed, the indoor temperature value acquired by the indoor temperature acquisition device within a set period of time is recorded, and then, according to the recorded indoor temperature value and the set period of time, an average indoor temperature value can be obtained.
Of course, the air conditioner control in the embodiment of the present disclosure may perform one-time control or automatic continuous control after the start operation of the air conditioner is completed, 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.
And obtaining the current average indoor temperature value, namely obtaining the current absolute average temperature difference value between the current average indoor temperature value and the target indoor temperature value.
Step 2003: the method includes determining a current operating frequency of an air conditioner compressor that matches a current absolute average temperature difference, and determining a current operating state of a current semiconductor component that matches the current absolute average temperature difference.
Generally, when an air conditioner is operated in modes of refrigeration, heating, dehumidification and the like, the greater the current absolute average temperature difference value is, the higher the operation frequency of the air conditioner compressor is, the compressor of the air conditioner operates in the current working mode according to the indoor temperature value within the current set time length for acquiring the indoor temperature value, and the current absolute average temperature difference value Trp-Tset is smaller than a set value, the compressor of the air conditioner may perform frequency reduction processing, so that the user experience and the energy consumption are both considered, and the temperature is stably controlled. Thus, in some embodiments, determining a current operating frequency of the air conditioning compressor that matches the current absolute average temperature difference value includes: acquiring a previous absolute average temperature difference value under the condition that the current absolute average temperature difference value is smaller than a first set temperature value; and under the condition that the absolute average temperature difference value of the previous time is smaller than the first set temperature value, performing frequency reduction processing on the air conditioner compressor, and determining the reduced operating frequency as the current operating frequency.
Wherein the first set temperature value may be 1.5 ℃, 2 ℃, 3 ℃, etc. Thus, after the air conditioner is started and operated, if the current absolute average temperature difference is greater than or equal to the first set temperature value, for example: the current absolute average temperature difference value |Trp-Tset|is equal to or greater than 2.5 ℃, indicating that the current absolute average temperature difference value |Trp-Tset| is relatively large, and thus, the operating frequency of the air conditioner compressor may not be adjusted, for example: the air conditioner compressor is still operating in the current mode of operation at the highest frequency. If the current absolute average temperature difference value |trp-tset| is smaller than the first set temperature value, for example: and Trp-Tset-2.5 deg.C, the temperature difference is small, i.e. the running frequency of air conditioner compressor can be unchanged or can be undergone the process of frequency-reducing treatment. When the absolute average temperature difference value is acquired and obtained, the absolute average temperature difference value of the previous time corresponding to the previous time setting duration is not available, and at the moment, when the current absolute average temperature difference value Trp-Tset is smaller than the first set temperature value, the running frequency of the air conditioner compressor can not be adjusted; if the absolute average temperature difference value is not acquired for the first time, the absolute average temperature difference value of the previous time can be acquired, and when the absolute average temperature difference value of the previous time is smaller than the first set temperature value, the air conditioner compressor can be indicated to have no need of high frequency, the frequency reduction processing can be performed, the reduced operating frequency is determined to be the current operating frequency, namely, when the average temperature difference value obtained by sampling for two or more times is smaller than the first set temperature value, the frequency reduction processing can be performed. Thus, not only the accuracy of temperature control can be ensured, but also the power consumption of the air conditioner can be saved. Of course, the frequency-reducing processing is relatively many, and frequency-reducing may be performed according to a set value or a set ratio, or frequency-reducing may be performed according to a set gear, which is not specifically exemplified.
In the embodiment of the disclosure, after the start operation of the air conditioner is completed, when the current absolute average temperature difference value is relatively large, the current semiconductor component matched with the current working mode can be started to operate, and the current operation state of the current semiconductor component can be determined to be the start operation state; and when the current absolute average temperature difference value is smaller, the current semiconductor component can be determined to be in a closed and stopped state without starting the current semiconductor component. Therefore, when the current absolute average temperature difference value is larger, the refrigerating capacity or heating capacity can be increased through the operation of the semiconductor components, and the refrigerating or heating efficiency of the air conditioner can be improved.
In some embodiments, determining a current operating state of the current semiconductor component that matches the current absolute average temperature difference value comprises: determining the shutdown state as a current running state of the current semiconductor component when the current absolute average temperature difference value is smaller than a first set temperature value; determining the starting operation state as the current operation state of the current semiconductor component under the condition that the current absolute average temperature difference value is larger than or equal to a first set temperature value; wherein the second set temperature value is greater than or equal to the first set temperature value.
The first set temperature value may be determined according to a location where the air conditioner is located, performance of the air conditioner, etc., and may be 1.5 c, 2 c, 3 c, etc.
For example, in the case of the air conditioner cooling mode operation, if the current absolute average temperature difference is greater than or equal to the first set temperature value, for example, when the absolute average temperature difference is equal to or greater than the first set temperature value, i.e., trp-Tset-I is equal to or greater than 3 ℃, the current operation state of the first semiconductor component can be determined as the start operation 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 cooling capacity of the air conditioner, and further improving the cooling efficiency of the air conditioner. And under the condition of air conditioner heating mode operation, if the current absolute average temperature difference value is greater than or equal to a first set temperature value, for example, when the absolute average temperature difference value is equal to or greater than or equal to 2.5 ℃ i.e. Trp-Tset, the current operation state of the second semiconductor component can be 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 the heating efficiency of the air conditioner.
Step 2004: 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.
In the current working mode, the air conditioner compressor can be controlled to operate at the current operating frequency, and the current semiconductor components are controlled to be in a closed stop state or a start operation state.
Under the condition that the current absolute average temperature difference value is larger than or equal to the first set temperature value, the current running state of the current semiconductor component is the starting running state, and at the moment, the current semiconductor component can be controlled to be always in the starting running state. Or, in a set period of time, controlling the semiconductor component to be in a starting operation state, for example: and controlling the semiconductor component to be in a starting operation state in the operation time of the set operation period of the semiconductor component.
Thus, controlling the current semiconductor component to operate in the current operating state includes: and under the condition that the current absolute average temperature difference value is larger than or equal to the first set temperature value, controlling the current semiconductor component to be in a starting operation state only in the operation time of the set operation 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 Trp-Tset I is not less than 3 ℃, the current semiconductor component is controlled to be in a starting operation state only within 10min of the set operation 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.
It can be seen that, in the embodiment of the present disclosure, two groups of semiconductor components are configured in an air conditioner, and when the air conditioner starts a current working mode, the current semiconductor component matched with the current working mode may be controlled to be in a starting operation state within a set starting time, so that, by first operating the semiconductor component for a period of time, a target indoor temperature value may be maintained for a long time in a room, so that not only is power consumption of the air conditioner saved, but also user experience is improved, and then, an operation state of an air conditioner compressor and the semiconductor component may be adjusted according to an absolute average temperature difference between an average indoor temperature value and the target indoor temperature value, thereby flexibly controlling power of the air conditioner, and, while improving refrigerating capacity or heating capacity of the air conditioner by controlling operation of the semiconductor component, improving refrigerating and heating efficiency, and reducing power consumption of the air conditioner.
The power of the semiconductor component is adjustable, and the corresponding output cold energy or heat energy is different, so that the semiconductor component can output different cold energy or heat energy 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 current operating state includes: determining a current running gear of the current semiconductor component corresponding to the current absolute average temperature difference value under the condition that the current absolute average temperature difference value is larger than or equal to a first set temperature value; and controlling the current semiconductor component to operate in the current operating gear within the operating time of the set operating 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 a current operating gear of the current semiconductor component corresponding to the current absolute average temperature difference comprises: under the condition that the current absolute average temperature difference value is in a first temperature range, determining a first gear as a current running gear of the current semiconductor component; under the condition that the current absolute average temperature difference value is in a second temperature range, determining a second gear as the current running gear of the current semiconductor component; and determining the third gear as the current running gear of the current semiconductor component under the condition that the current absolute average temperature difference value is in the third temperature range.
The lower limit value of the first temperature range is equal to the second set temperature value, the upper limit value of the first temperature range is equal to the lower limit value of the second temperature range, the upper limit value of the second temperature range is equal to the lower limit value of the third temperature range, 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 2.5 ℃, the first temperature range may be [2.5,4.8 ], the second temperature range may be [4.8,6.5), and the third temperature range may be [6.5, ++). Thus, when the temperature is 2.5 ℃ less than or equal to-Trp-Tset less than or equal to 4.8 ℃, the first gear can be determined as the current running gear of the current semiconductor component; when the temperature is less than or equal to 4.8 ℃ and less than or equal to-Trp-Tset-is less than 6.5 ℃, the second gear can be determined as the current running gear of the current semiconductor component; and when the temperature is less than or equal to minus Trp-Tset minus 6.5 ℃, the third gear can be determined to be the current running gear of the current semiconductor component.
Of course, the semiconductor components correspond to two, four, five, etc. operating gears, and the corresponding current operating gear of the current semiconductor component may also be determined according to the current absolute average temperature difference value, which will not be described in detail.
After the start-up operation of the air conditioner is completed, air conditioner control may be performed twice or more continuously, and thus, the current operation gear of the current semiconductor device may be determined according to the current absolute average temperature difference value and the previous absolute average temperature difference value.
In some embodiments, determining the current operating range of the current semiconductor component without obtaining the previous absolute average temperature difference comprises: if the current absolute average temperature difference value is in the fourth temperature range, determining the second gear as the current running gear of the current semiconductor component; and if the current absolute average temperature difference value is in the fifth temperature range, determining the third gear as the current running gear of the current semiconductor component.
The lower limit value of the fourth temperature range is equal to the first set temperature value, the upper limit value of the fourth temperature range is equal to the lower limit value of the fifth temperature range, 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 first set temperature value is 2.5 ℃, the fourth temperature range can be [2.5,5.5 ], and the fifth temperature range can be [5.5, +.. Thus, after the starting operation of the air conditioner is finished, the temperature is acquired for the first time and the current absolute average temperature difference value is obtained, at the moment, no absolute average temperature difference value exists in the last time, and if the temperature of the air conditioner is equal to or lower than 2.5 ℃ and the temperature of the Trp-Tset is equal to or lower than 5.5 ℃, the second gear can be determined to be the current operation gear of the current semiconductor component; and when the temperature is less than or equal to minus Trp-Tset minus 5.5 ℃, the third gear can be determined to be the current running gear of the current semiconductor component.
In some embodiments, determining the current operating range of the current semiconductor component if the previous absolute average temperature difference was obtained comprises: determining a previous operating gear of the current semiconductor component as the current operating gear of the current semiconductor component under the condition that the current absolute average temperature difference value is larger than or equal to a first set temperature value and the previous absolute average temperature difference value is larger than or equal to the first set temperature value; and under the condition that the current absolute average temperature difference value is larger than or equal to the first set temperature value and the previous absolute average temperature difference value is smaller than the first set temperature value, performing downshift processing on the current semiconductor component, and determining the lowered operation gear as the current operation gear of the current semiconductor component.
Wherein, the downshifting the current semiconductor component may include: if the previous operating gear of the current semiconductor component is not the lowest gear, the previous operating gear can be reduced by one gear, and the reduced gear is determined as the current operating gear of the current semiconductor component. If the last operating gear of the current semiconductor component is the lowest gear, the lowest gear may be determined to be the current operating gear of the current semiconductor component. For example: if the previous running gear is the third gear, the second gear can be determined as the current running gear; if the previous running gear is the second gear, the first gear can be determined to be the current running gear; and if the previous operating gear is the lowest first gear, the first gear may be determined to be the current operating gear.
The current operating gear of the current semiconductor component is determined, so that the current semiconductor component can be controlled to operate in the current operating gear, or the current semiconductor component can be controlled to operate in the current operating gear in a set time period. In some embodiments, the current semiconductor component may be controlled to operate in a current operating gear during an operating time of a set operating cycle of the semiconductor component.
For example: when the absolute average temperature difference value of the previous time is not obtained and the absolute average temperature difference value of the current absolute average temperature difference value of Trp-Tset of 2.5 ℃ is smaller than or equal to the absolute average temperature difference value of the current absolute average temperature of 2.5 ℃ and is smaller than 5 ℃, 220v voltage can be provided for the current semiconductor component within 10min operation time of 20min set operation period of the semiconductor component, 1A current is provided, and the current semiconductor component is controlled to operate in a middle gear. Or when the absolute average temperature difference value (Trp-Tset) is equal to or greater than 5 ℃, 220v voltage and 1.5A current can be provided for the current semiconductor component in 10min running time of the 20min set running period of the semiconductor component, and the current semiconductor component is controlled to run in a high gear. When Trp-Tset-2.5 ℃, the current semiconductor device can be controlled to be in a closed and stopped state.
Or acquiring the absolute average temperature difference value of the previous time, and controlling the current semiconductor component to still operate in the previous operation gear within 10min of the operation time of the 20min set operation period of the semiconductor component if the absolute average temperature difference value of the previous time, namely, trp-Tset I is not less than 2 ℃ and the current absolute average temperature difference value of the current absolute average temperature is not less than 2 ℃; if the absolute average temperature difference value I Trp-Tset I is not less than 2 ℃ before, the absolute average temperature difference value I Trp-Tset I is not less than 2 ℃, the current semiconductor component needs to be subjected to the downshift treatment, and the current semiconductor component can be controlled to operate in the reduced operation gear within the 10min operation time of the 20min set operation period of the semiconductor component.
It can be seen that in some embodiments, different current absolute average temperature differences correspond to different operation gears of the semiconductor component, that is, correspond to different output energies of the semiconductor component, thereby further accelerating the cooling or heating efficiency of the air conditioner. In addition, in the running time of the set running period of the semiconductor component, the semiconductor component is in a starting running state, and in the stopping time of the set running period of the semiconductor component, the semiconductor component is in a closing stopping state, so that the semiconductor component cannot be continuously started for a long time, the stability of the semiconductor component is ensured, and the energy consumption of an air conditioner is reduced.
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. Thus, in some embodiments, controlling the current semiconductor component to operate in the current operating range further comprises: and controlling the operation of the corresponding exhaust fan on the current semiconductor component according to the current working 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.
In the embodiment of the present disclosure, the control process of the air conditioner may perform one-time control or automatic continuous control after the start-up operation of the air conditioner is completed, so in some embodiments, obtaining the current average indoor temperature value in the current set duration of the area where the air conditioner is operated in the current working mode includes: when 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, recording an indoor temperature value of an area where the air conditioner is running in the current working mode in the current set duration time; and obtaining the current average indoor temperature value in the current set time according to the recorded indoor temperature value.
For example: the preset sampling duration may be 5, 10, 15, 25 minutes, etc., so that in the preset sampling duration, the semiconductor component is not started to operate all the time, is in a closed and stopped state, and the air conditioner is also operated in the current working mode all the time, at this time, temperature sampling and recording can be performed for the current set time, so as to obtain the current average indoor temperature value in the current set duration, further obtain the current absolute average temperature difference value, and then air conditioner control can be performed continuously according to the current absolute average temperature difference value.
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.

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. And, the fourth temperature range may be [2, 5), and the fifth temperature range may be [5, ++); the set duration may be 10min, the set operation period of the semiconductor device may be 20min, and the operation time of the set operation period may be 10min; the set starting time can be the running time of the set running period and is also 10 minutes; the preset sampling duration may also be 10 minutes.

The air conditioner is started to perform heating mode starting, wherein a starting operation module 4100 controls the air conditioner compressor to perform current working mode operation at the highest frequency, and controls the second semiconductor components matched with the current working mode to be in a starting operation state within a set starting time of 15 min.
After the start-up operation of the air conditioner is completed, the second semiconductor component is in a stop state. Then, if the two semiconductor devices are in a stopped state and the duration of the air conditioner in the heating mode operation state reaches 15min, the first obtaining module 4200 may record the indoor temperature value of the air conditioner in the heating mode operation within 12min, obtain the current average indoor temperature value Trp within 12min, and obtain the current absolute average temperature difference value i Trp-Tset according to the current average indoor temperature value Trp and the target indoor temperature value Tset.
Thus, if the current absolute average temperature difference is obtained by the first sampling, that is, the previous absolute average temperature difference is not obtained, the mode determining unit 4320 may determine the shutdown state as the current operation state of the second semiconductor device if i Trp-Tset i < 2.5. Thus, the control module 4300 may control the air conditioner to perform heating operation, and control the second semiconductor component to be in a closed shutdown state, and control the third exhaust fan on the second heating end of the second semiconductor component to be closed, and the fourth exhaust fan on the second cooling end to be closed. Of course, the current absolute average temperature difference may also be saved as the previous average temperature difference, the current operating frequency as the previous operating frequency, and the current operating gear as the previous operating gear. And 2.5 < l Trp-Tset <5.5, the mode determining unit 4320 may determine the start-up operation state as the current operation state of the second semiconductor device. And the gear determining unit 4410 in the first control module 4400 may determine that the second gear is the current operation gear of the second semiconductor component. If the value of the threshold value is equal to or less than 5.5-Trp-Tset-again, the mode determining unit 4320 may determine the start-up operation state as the current operation state of the second semiconductor device. And the gear determining unit 4410 may determine that the third gear is the current operation gear of the second semiconductor component. Thus, the first control unit 4420 in the first control module 4400 may control the second semiconductor component to operate in a current operating range, and control the third exhaust fan on the second heating side of the second semiconductor component to operate, and the fourth exhaust fan on the second cooling side to operate.
When reaching the operation time of 15min with the set operation period of the semiconductor components, the second control unit 4430 may control the second semiconductor components to be in a shutdown state, and control the third exhaust fan on the second heating end of the second semiconductor components to be turned off, and the fourth exhaust fan on the second cooling end to be turned off. And the current absolute average temperature difference value is stored as the previous average temperature difference value, the current operating frequency is stored as the previous operating frequency, and the current operating gear is stored as the previous operating gear.
After the air conditioner is started to operate, the current absolute average temperature difference value is obtained by sampling the air conditioner for the first time, and the previous absolute average temperature difference value can be obtained, so that if the current absolute average temperature difference value is
Trp-Tset- <2.5, the mode determining unit 4320 may still determine the shutdown state as the current operation state of the second semiconductor device. Meanwhile, if the absolute average temperature difference value of the previous time is Trp-Tset I
<2.5, the frequency determining unit 4310 may perform a down-conversion process on the air conditioner compressor and determine the reduced operation frequency as the current operation frequency.
In this way, the first control module 4400 may control the air conditioner to perform heating operation according to the current operation frequency, and control the second semiconductor component to be in a closed and stopped state, and control the third exhaust fan on the second heating end of the second semiconductor component to be closed, and the fourth exhaust fan on the second cooling end to be closed. Of course, the current absolute average temperature difference may also be saved as the previous average temperature difference, the current operating frequency as the previous operating frequency, and the current operating gear as the previous operating gear.
If the current absolute average temperature difference value i Trp-Tset i is equal to or greater than 2.5 and the previous absolute average temperature difference value i Trp-Tset i is equal to or greater than 2.5, the mode determining unit 4320 may determine the start-up operation state as the current operation state of the second semiconductor device, and the gear determining unit 4410 may determine the previous operation gear of the second semiconductor device as the current operation gear of the second semiconductor device. If the current absolute average temperature difference value (Trp-Tset) is equal to or greater than 2.5 and the previous absolute average temperature difference value (Trp-Tset)
<2.5, the mode determining unit 4320 may determine the start-up operation state as the current operation state of the second semiconductor component, and the gear determining unit 4410 may perform a downshift process to the second semiconductor component, and determine the lowered operation gear as the current operation gear of the second semiconductor component.
Thus, the first control unit 4420 in the first control module 4400 may control the second semiconductor component to operate in a current operating range, and control the third exhaust fan on the second heating side of the second semiconductor component to operate, and the fourth exhaust fan on the second cooling side to operate.
When reaching the operation time of 15min with the set operation period of the semiconductor components, the second control unit 4430 may control the second semiconductor components to be in a shutdown state, and control the third exhaust fan on the second heating end of the second semiconductor components to be turned off, and the fourth exhaust fan on the second cooling end to be turned off. And the current absolute average temperature difference value is stored as the previous average temperature difference value, the current operating frequency is stored as the previous operating frequency, and the current operating gear is stored as the previous operating gear.
Therefore, after the start operation is completed, the running parameters and states of the air conditioner compressor and the semiconductor components are adjusted according to the absolute average temperature difference between the average indoor temperature value and the target indoor temperature value, so that the power of the air conditioner is flexibly controlled, and 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 power consumption of the air conditioner is reduced. In addition, the semiconductor components which are operated for a period of time can be ensured to be maintained at the target indoor temperature value for a long time, and the efficiency and the user experience of the air conditioner are improved.
