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, the air conditioner performs the starting operation of the current working mode in the set starting time, and when the exhaust temperature is too high in the starting operation, the current semiconductor component matched with the current working mode is controlled to be in the starting operation state, so that the semiconductor component which is operated for a period of time in the room can be maintained at the target indoor temperature value for a long time, the power consumption of the air conditioner is saved, the user experience is improved, and then, after the starting operation is finished, the operation parameters and states of the air conditioner compressor and the semiconductor component can be adjusted according to the average exhaust temperature value, so that the power of the air conditioner is flexibly controlled, the refrigerating capacity or the heating capacity of the air conditioner can be improved by controlling the operation of the semiconductor component, the refrigerating and heating efficiency is improved, and the power consumption of the air conditioner is reduced. In addition, the operation state of the air conditioner compressor can be judged through the detected exhaust temperature and the detected return air temperature, if the air conditioner compressor has a fault, the air conditioner compressor and the air conditioner are protected, and the service life of the air conditioner is prolonged.
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: and when the running time of the air conditioner running in the current working mode reaches the set starting time, if the first average exhaust temperature value in the set exhaust time length of the air conditioner is greater than or equal to the second set exhaust temperature value, controlling the current semiconductor component matched with the current working mode to be in a starting running state in the running time of the set running period of the semiconductor component.
In the embodiment of the disclosure, when the air conditioner is started to operate, vapor compression 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: the operation is performed for 20min, which indicates that the air conditioner is in a stable operation state, at this time, the exhaust temperature value of the air conditioner can be collected by the exhaust temperature collecting device, and a first average exhaust temperature value in a set exhaust time period is obtained, wherein the set exhaust time period can be 5, 8, 10 or 15min, and the like. Thus, if the first average exhaust temperature value is greater than or equal to the second set exhaust temperature value, it indicates that in the set starting time, the air conditioner is operated by the compressor, and still cannot provide enough refrigerating capacity or heating capacity, the exhaust temperature of the air conditioner is higher, and the operation frequency of the air conditioner compressor is higher.
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. Thus, the air conditioner may operate the current semiconductor device for 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. Thus, in this implementation, the period of time may be the time at which the run period is set. At this time, controlling the current semiconductor component matched with the current operation mode to be in a start-up operation state includes: and controlling the current semiconductor component matched with the current working mode to start and run for one period, namely, in the running time of the set running period of the semiconductor component, the current semiconductor component matched with the current working mode is in a starting running state. Of course, in some embodiments, the semiconductor may perform periodic operation, but the current semiconductor component may be controlled to be in a start-up operation state within any period of time without performing periodic control on the current semiconductor component, 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.
Thus, in some embodiments, controlling the current semiconductor component that matches the current operating mode to be in a start-up operational state includes: and controlling the current semiconductor component matched with the current working mode to operate in a second gear in the running time of the set running period of the semiconductor component, wherein the semiconductor component comprises three gears, 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.
Of course, the current semiconductor component may be controlled to operate in the first gear or the third gear for one period, that is, in the operation time of the set operation period of the semiconductor component, the current semiconductor component matched with the current operation mode may be controlled to operate in the first gear or the third gear, which is not specifically exemplified.
Step 2002: and under the condition that the current semiconductor component is in a closed and stopped state after finishing the starting running state, and the duration time of the air conditioner in the current mode running state reaches the preset sampling duration time, acquiring the current average exhaust temperature value in the current set duration time of the air conditioner.
After the air conditioner is started to run, and after the current semiconductor component finishes the starting running state, the current semiconductor component can be controlled to be in a closing and stopping state. And, the air conditioner still operates the current operation mode.
In the embodiment of the disclosure, the air conditioner is provided with the exhaust temperature acquisition device, so that the average exhaust temperature value can be obtained by recording the exhaust temperature value acquired by the exhaust temperature acquisition device within a set period of time after the current semiconductor component completes the starting operation state and then according to the recorded exhaust temperature value and the set period of time.
Of course, in the embodiment of the present disclosure, after the current semiconductor component completes the start-up operation state, one-time control or automatic continuous control may be performed, so if the previous semiconductor component is in the shutdown state after completing the start-up operation state, and the duration of the air conditioner in the current mode operation state reaches the preset sampling duration, one-time sampling may be performed, and the current setting duration corresponding to the current sampling corresponds to the current average exhaust temperature value.
The preset sampling duration may be 5 minutes, 10 minutes, 15 minutes, 20 minutes, or the like, and the set duration may be 1 minute, 5 minutes, 10 minutes, or 20 minutes, or the like, and in some embodiments, the current set duration may be zero, where the current average exhaust temperature value is a real-time current exhaust temperature value acquired by the exhaust temperature acquisition device.
Step 2003: and controlling the operation of the current semiconductor component according to the current average exhaust temperature value.
Generally, when an air conditioner is operated in modes of cooling, heating, dehumidifying and the like, when the exhaust temperature is high, it is indicated that the air conditioner needs to increase the cooling capacity or heating capacity. Thus, a first set exhaust temperature value, and a second set exhaust temperature value, for example: the first set exhaust temperature value may be 80 ℃, 82 ℃, 83 ℃, 85 ℃, or the like. The second set exhaust temperature value may be 88 ℃, 90 ℃, 93 ℃, 95 ℃ or the like, and may be specifically determined according to the area and performance of the air conditioner.
Thus, if the current average exhaust temperature value is smaller than the first set exhaust temperature value, the current semiconductor component can be controlled to be in a closed and stopped state; and under the condition that the current average exhaust temperature value is larger than or equal to the first set exhaust temperature value, the current semiconductor component can be controlled to be in a starting running state.
Of course, in some embodiments, the semiconductor component does not continuously operate for a long period of time, but periodically operates, so that in the case where the current average exhaust temperature value is greater than or equal to the first set exhaust temperature value, the current semiconductor component may be controlled to be in the start-up operation state during the operation time of the set operation period of the semiconductor component.
The current semiconductor component can be controlled to operate once, however, in some embodiments, the current semiconductor component is in a closed and stopped state after the current semiconductor component completes the start-up operation state, and the air conditioner can sample and control under the condition that the duration of the current mode operation state reaches the preset sampling duration, so that the periodic operation of the semiconductor component is realized. That is, when the air conditioner starts to run and reaches the set starting time, and the first average exhaust temperature value in the set exhaust time length is greater than or equal to the second set exhaust temperature value, the current semiconductor component matched with the current working mode can be controlled to run periodically according to the current average exhaust temperature value after the current semiconductor component finishes one-time starting operation.
In some embodiments, the semiconductor components correspond to two or more operating ranges, and thus, controlling the current semiconductor component operation based on the current average exhaust temperature value may include: and determining the current gear of the current semiconductor component according to the current average exhaust temperature value, and controlling the current semiconductor component to operate in the current gear within the operation time of the set operation period of the semiconductor component, wherein 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 gear is.
In the control of the periodic operation of the semiconductor component, the current average exhaust temperature value is collected for the first time, and the number of times of the periodic operation of the semiconductor component, which is not recorded, and the corresponding previous operation state, previous operation gear, etc., while in the subsequent continuous control, the number of times of the operation, and the corresponding previous operation state, previous operation gear, etc., are recorded, so that different recording conditions can correspond to different semiconductor component control processes.
In some embodiments, in a case where the recorded number of times of periodic operation of the semiconductor component is zero, controlling the current semiconductor component to be in the start-up operation state includes: when the current average exhaust temperature value is larger than or equal to the second set exhaust temperature value, controlling the current semiconductor component to operate at the highest gear in the operation time of the set operation period; and controlling the current semiconductor component to operate in a non-highest gear within the operation time of the set operation period under the condition that the current average exhaust temperature value is larger than or equal to the first set exhaust temperature value and smaller than the second set exhaust temperature value.
The recorded running times of the periodic running of the semiconductor components are zero, namely the starting running of the air conditioner reaches the set starting time, and the current semiconductor components matched with the current working mode are sampled for the first time after the current semiconductor components are started to run for one time because the first average exhaust temperature value in the set exhaust time is larger than or equal to the second set exhaust temperature value, and the semiconductor components are not periodically controlled, at the moment, if the first set exhaust temperature value is 87 ℃, the second set exhaust temperature value is 97 ℃, if the current average exhaust temperature value Tpp is larger than or equal to 92 ℃, the current semiconductor components are controlled to run in a third gear within 15min of the running time of 30min of the set running time, and if the temperature is 87 ℃ or smaller than 92 ℃, the current semiconductor components are controlled to run in a second gear or run in a first gear within 15min of the running time of 30min of the set running time. The semiconductor components comprise three gears, wherein 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.
Thus, after the running time of the set running period of the semiconductor component is reached, the current semiconductor component can be controlled to be in a closed and stopped state, then, under the condition that the current semiconductor component is in the closed and stopped state after the current semiconductor component finishes the starting running state and the duration time of the air conditioner in the current mode running state reaches the preset sampling duration time, the sampling can be continued, the control of the semiconductor component is continued, at the moment, the recorded running times of the periodic running of the semiconductor component are not zero, and accordingly, the running of the current semiconductor component can be controlled according to the previous running gear, the previous running gear and the current average exhaust temperature value. Therefore, after each time of periodical control of the semiconductor component, the running times of periodical running of the semiconductor component, the corresponding running states and running gears are recorded.
In some embodiments, in a case where the recorded number of times of periodic operation of the semiconductor component is not zero, controlling the current semiconductor component to be in the start-up operation state includes:
in the recorded running state of the current semiconductor component, under the condition that the number of times of continuous running in the previous gear is less than 2, if the current average exhaust temperature value is greater than or equal to the first set exhaust temperature value, determining the previous running gear as the current running gear, and controlling the current semiconductor component to run in the current running gear in the running time of the set running period; in the recorded running state of the current semiconductor component, continuously running for times greater than or equal to 2 times in the previous gear, and under the condition that the previous running gear is not the highest gear, if the current average exhaust temperature value is greater than or equal to the first set exhaust temperature value, performing upshift processing on the current semiconductor component, determining the elevated running gear as the current running gear of the current semiconductor component, and controlling the current semiconductor component to run in the current running gear in the running time of the set running period; in the recorded running state of the current semiconductor component, the number of times of continuous running in the previous gear is more than or equal to 2, and under the condition that the previous running gear is the highest gear, if the current average exhaust temperature value is more than or equal to the first set exhaust temperature value and less than the second set exhaust temperature value, controlling the current semiconductor component to run in the highest gear in the running time of the set running period, and resetting the recorded running number of times of periodic running after the running is finished; and in the recorded running state of the current semiconductor component, continuously running for times greater than or equal to 2 times in the previous gear, and under the condition that the previous running gear is the highest gear, if the current average exhaust temperature value is greater than or equal to the second set exhaust temperature value, acquiring the current average return air temperature value of the air conditioner within the set return air time period, and controlling the running of the air conditioner compressor according to the current average return air temperature value.
For example: the first set exhaust temperature value is 83 deg.c and the second set exhaust temperature value is 90 deg.c. If the number of times of continuous operation in the previous gear is less than 2 in the recorded operation state of the current semiconductor component, that is, the previous operation gear is different from the previous gear, wherein when the number of times of periodic operation in the recorded semiconductor component is 1, only the previous operation gear is not present, so that the previous operation gear is different from the previous operation gear, that is, the number of times of continuous operation in the previous gear is less than 2, so that, because Tpp is greater than or equal to 83 ℃, the current operation state of the current semiconductor component is the starting operation state, and the previous operation gear can be determined as the current operation gear, and therefore, the current semiconductor component can be controlled to operate in the current operation gear within the operation time of the set operation period.
In the recorded running state of the current semiconductor component, the number of continuous running times of the previous running gear is greater than or equal to 2, namely the previous running gear is the same as the previous running gear, at the moment, tpp is more than or equal to 83 ℃, which indicates that the previous running gear is run twice or more, and Tpp is higher, then the current semiconductor component is required to be subjected to upshift treatment so as to improve the refrigerating capacity or heating capacity, therefore, if the previous running gear is not the highest gear, the current semiconductor component can be subjected to upshift treatment, the risen running gear is determined as the current running gear of the current semiconductor component, and the current semiconductor component is controlled to run in the current running gear in the running time of the set running period. If the previous operating gear is the highest gear, the control is performed according to the Tpp, wherein the Tpp is high, which indicates that the compressor may have faults, so that the current semiconductor component can be controlled to operate at the highest gear within the operating time of the set operating period if the temperature is 83 ℃ or less and the Tpp is less than 90 ℃, but after the operation is finished, the recorded number of times of periodic operation is not increased by 1, but the recorded number of times of periodic operation is cleared, namely, the control starting point of periodic operation of the semiconductor component is returned. Whereas if 90 ℃ is less than or equal to Tpp, the highest gear is operated twice or more, but Tpp is high, indicating that the compressor may malfunction. At this time, the operation of the air conditioner compressor may be controlled according to the current average return air temperature value.
In some embodiments, controlling operation of the air conditioning compressor includes: under the condition that the current average return air temperature value is greater than or equal to the set return air temperature value, controlling the air conditioner compressor to stop running, and carrying out fault reminding treatment; and under the condition that the current average return air temperature value is smaller than the set return air temperature value, controlling the air conditioner compressor to carry out frequency reduction processing, and under the condition that the frequency reduction operation duration of the air conditioner compressor reaches the set frequency reduction duration, resetting the recorded operation times of periodic operation.
The air conditioner is also provided with an air return temperature acquisition device, and the current average air return temperature value of the air conditioner can be obtained within a set air return time length through the air return temperature acquisition device, wherein the set air return time length can be the same as or different from the set time length and can be 5, 8, 10, 15 mm or the like. Thus, if the current average return air temperature value Thp is greater than or equal to the set return air temperature value, for example: the temperature of 25 ℃, 30 ℃ or 35 ℃ and the like indicate that the compressor is out of order, and the air conditioner outdoor unit possibly causes the compressor to be out of order due to air leakage, refrigerant leakage, indoor unit failure and the like, can carry out failure reminding processing, and stops the operation of the compressor, so that the compressor can be timely protected, and the service lives of the compressor and the air conditioner are prolonged.
If the current average return air temperature value Thp is smaller than the set return air temperature value, the air conditioner compressor may be subjected to a frequency-reducing process, for example: and reducing the running frequency of the air conditioner compressor according to the speed of 1HZ/min, and clearing the recorded running times of the periodic running under the condition that the time length of the down-conversion running of the air conditioner compressor reaches the set down-conversion time length, namely returning to the control starting point of the periodic running of the semiconductor component again.
In the periodic control of the semiconductor component, if the current average exhaust temperature value is smaller than the first set exhaust temperature value, the current semiconductor component is controlled to be in a closed and stopped state. When the periodic control of the semiconductor component is performed again, the previous running state of the current semiconductor is the shutdown state, and at this time, the control of the current semiconductor component in the startup running state includes: under the condition that the current average exhaust temperature value is larger than or equal to a first set temperature value, if the previous running gear is the highest gear, performing downshifting treatment on the current semiconductor component, determining the reduced gear as the current running gear, and controlling the current semiconductor component to run in the current running gear in the running time of the set running period; and under the condition that the current average exhaust temperature value is greater than or equal to the first set temperature value, if the previous running gear is not the highest gear, resetting the recorded running times of periodic running, and controlling the current semiconductor component to be in a starting running state according to the current average exhaust temperature value.
For example: the first set temperature value is 85 ℃, so that the previous running state is a closed shutdown state, at this time, 85 ℃ is less than or equal to Tpp, and when the previous running gear is the highest gear, the current semiconductor component is subjected to downshifting treatment, the reduced gear is determined as the current running gear, and the current semiconductor component is controlled to run in the current running gear within the running time of the set running period.
And when the temperature is less than or equal to 85 ℃ and is less than or equal to Tpp and the previous running gear is not the highest gear, the recorded running times of the periodic running are cleared, and the current semiconductor component is controlled to be in a starting running state according to the current average exhaust temperature value, namely, the control starting point of the periodic running of the semiconductor component is returned.
Therefore, the semiconductor components which are matched with the current working mode are controlled to be in a starting operation state when the operation time of the air conditioner in the current working mode reaches the set starting time and the exhaust temperature is too high, so that the semiconductor components which are operated for a period of time can be maintained at the target indoor temperature value for a long time in the room, the power consumption of the air conditioner is saved, the user experience is improved, then, after the starting operation is finished, the operation parameters and states of the air conditioner compressor and the semiconductor components can be adjusted according to the average exhaust temperature value, the power of the air conditioner is flexibly controlled, the refrigerating capacity or the heating capacity of the air conditioner can be 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. In addition, the operation state of the air conditioner compressor can be judged through the detected exhaust temperature and the detected return air temperature, if the air conditioner compressor has a fault, the air conditioner compressor and the air conditioner are protected, and the service life of the air conditioner is prolonged.
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 be in a start-up operational state 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.
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.
