Fig. 1 is a schematic diagram of a method for cleaning an air conditioner according to an embodiment of the present disclosure.
Referring to fig. 1, an embodiment of the present disclosure provides a method for cleaning an air conditioner, which may be used to kill bacteria, mold, etc. inside the air conditioner and reduce the number of microorganisms breeding; in this embodiment, the method includes:
s101, responding to a cleaning instruction, heating the surface temperature of a target heat exchanger to a first sterilization temperature, and performing high-temperature sterilization;
in some optional embodiments, cleaning options such as "sterilization function" or "sterilization function" are added to the remote controller and the control panel of the air conditioner, and the cleaning options can be used to trigger the operation of the method flow for cleaning the air conditioner in this embodiment; thus, after the user selects the cleaning option, the air conditioner generates a relevant cleaning instruction and responds to the execution.
In still other alternative embodiments, the air conditioner may also generate the related cleaning instruction by detecting a trigger, a timing trigger, or the like, for example, the air conditioner is additionally provided with a microorganism detection device, which may be used to detect the content of one or more specific types of microorganisms, and when the detected content of the microorganisms is higher than a set content threshold, it indicates that the air conditioner has a large number of microorganisms, and the air conditioner generates the related cleaning instruction; still alternatively, the air conditioner has a timing module, which is configured to count the cumulative operating time of the air conditioner, such as the cumulative operating time of the cooling mode or the dehumidifying mode, wherein as the cumulative operating time of the cooling mode or the dehumidifying mode of the air conditioner increases, the more condensed water is condensed inside the air conditioner and the more the number of microorganisms in the humid environment increases, so that the air conditioner may be configured to generate the related cleaning instruction when the cumulative operating time of the air conditioner exceeds the set time threshold.
In still other alternative embodiments, the air conditioner may also be triggered in linkage with the original cleaning function of the air conditioner, for example, after the original cleaning function is selected by a user, a cleaning instruction is generated and the cleaning method flow defined by the original cleaning function is executed before the cleaning flow defined by the original cleaning function is executed, or a cleaning instruction is generated and the cleaning method flow defined by the original cleaning function is executed after the cleaning flow defined by the original cleaning function is executed; that is, after the user selects an original cleaning function, the air conditioner executes two different cleaning processes in sequence, and the cleanliness of the interior of the air conditioner is effectively guaranteed through a double cleaning mode.
For example, the original cleaning function of the air conditioner is a spray cleaning function, the spray cleaning function is to spray water onto a heat exchanger of the air conditioner to clean the heat exchanger in a flowing water flushing manner, and an optional implementation manner is that the cleaning method flow of the present application is operated before the spray cleaning function is executed, that is, after the spray cleaning function is selected by a user, the cleaning method flow of the present application is controlled to kill microbes such as bacteria and the like, and then the spray cleaning function is executed, so that the flowing water can not only flush dirt such as dust, oil stains and the like, but also flush the killed microbes on the heat exchanger.
In this embodiment, an indoor heat exchanger is mainly taken as an example of the target heat exchanger, and when step S101 is executed, the air conditioner adjusts the flow direction of the refrigerant in the system to be consistent with the flow direction of the refrigerant in the heating mode, so that the high-temperature refrigerant discharged by the compressor first flows through the indoor heat exchanger, so as to heat the indoor heat exchanger by using the heat of the high-temperature refrigerant, heat the surface temperature of the indoor heat exchanger to a first sterilization temperature, and perform high-temperature sterilization.
Optionally, the first sterilization temperature is greater than or equal to 60 ℃. Under the condition that the surface of the indoor heat exchanger is at the temperature, microorganisms such as bacteria, mold and the like bred on the surface of the indoor heat exchanger are heated and die gradually, so that the effects of sterilization and disinfection are achieved. In this example, the first sterilization temperature was 65 ℃.
And S102, after the high-temperature sterilization condition is met, reducing the surface temperature of the target heat exchanger to a second sterilization temperature, and performing quick cooling sterilization.
In some alternative embodiments, the autoclaving conditions include:
Te≥T1sterilizationAnd t isHigh temperature≥t1；
Wherein, TeIn the embodiment of the present disclosure, the temperature of the coil of the indoor heat exchanger is used as a parameter for measuring the surface temperature of the indoor heat exchanger, and when the coil temperature is greater than the first sterilization temperatureThe surface temperature of the indoor heat exchanger can be regarded as being higher than the sterilization temperature; t1SterilizationIs the first sterilization temperature, tHigh temperatureThe duration of the autoclaving is t1, the autoclaving duration threshold.
Optionally, t1 is greater than or equal to 30 minutes. According to the test, when the surface temperature of the indoor heat exchanger is greater than or equal to the first sterilization temperature for a duration of greater than or equal to 30 minutes, the actual sterilization effect is better, and t1 is 35 minutes in the embodiment.
The air conditioner is provided with a temperature sensor at the position of a coil of the indoor heat exchanger, and the temperature sensor can be used for detecting the real-time temperature of the coil of the indoor heat exchanger; meanwhile, the air conditioner is also provided with a timing module for counting the duration of high-temperature sterilization of the indoor heat exchanger, and the timing module starts timing when the temperature of the coil of the indoor heat exchanger in the step S101 is greater than or equal to the first sterilization temperature. Here, the timer module is cleared after determining that the high temperature sterilization condition is satisfied.
In this embodiment, if the high-temperature sterilization condition is not satisfied, the high-temperature sterilization flow of step S101 is continuously executed.
In some optional embodiments, when the rapid cooling sterilization process in step S102 is executed, the air conditioner adjusts the flow direction of the refrigerant in the system to be consistent with the flow direction of the refrigerant in the refrigeration mode, so that the high-temperature refrigerant discharged by the compressor flows through the outdoor heat exchanger first, and then the low-temperature refrigerant after throttling and pressure reduction is input into the indoor heat exchanger, so as to absorb the heat of the indoor heat exchanger by using the "cold energy" of the low-temperature refrigerant, cool the indoor heat exchanger, reduce the surface temperature of the indoor heat exchanger to the second sterilization temperature, and perform rapid cooling sterilization.
Optionally, the value range of the second sterilization temperature is less than or equal to 5 ℃. Here, because the indoor heat exchanger is in a state with a higher temperature in the previous high-temperature sterilization stage, and the indoor heat exchanger is switched to a state with a lower temperature in the next quick cold sterilization stage, the surface temperature of the indoor heat exchanger is greatly changed by cold and heat, and experiments prove that the rapid change process of the cold and the heat from high temperature to low temperature can effectively inactivate microorganisms, thereby realizing the effect of strengthening the sterilization. In this example, the second sterilization temperature was 5 ℃.
In some optional embodiments, after performing step S102, if the rapid cooling sterilization condition is satisfied, the control unit exits the rapid cooling sterilization.
Optionally, the rapid cooling sterilization conditions include:
Te≤T2sterilizationAnd t isLow temperature≥t2；
Wherein, T2SterilizationIs the second sterilization temperature, tQuick coolingThe duration of the rapid cooling sterilization is t2, and the threshold value of the duration of the rapid cooling sterilization is t 2.
Optionally, t2 is in a range of 10 minutes or longer. T2 was 10 minutes in this example.
Here, the timing module may be further configured to count a duration of the rapid cooling sterilization performed by the indoor heat exchanger, and the timing module starts timing when the coil temperature of the indoor heat exchanger during the step S102 is less than or equal to the second sterilization temperature. Here, after determining that the quick-cooling sterilization condition is satisfied, the timer is cleared.
In this embodiment, if the quick cooling sterilization condition is not satisfied, the quick cooling sterilization flow of step S102 is continuously executed.
The method for cleaning the air conditioner can kill bacteria breeding on the heat exchanger of the air conditioner through two processes of high-temperature sterilization and quick-cooling sterilization in sequence, wherein the high-temperature sterilization utilizes higher temperature to kill the bacteria, and the quick-cooling sterilization utilizes rapid change of cold and heat from high temperature to low temperature to kill the bacteria; the method can effectively reduce microorganisms such as bacteria, mold and the like on the heat exchanger, thereby improving the cleanness degree of the interior of the air conditioner.
In this embodiment, in order to ensure the sterilization effect in the two stages of high-temperature sterilization and rapid-cooling sterilization, the sterilization effect is mainly achieved by controlling the working parameters of the components such as the indoor fan, the air deflector, the outdoor fan, the throttling device, the compressor and/or the four-way valve, and the parameter control in each stage is respectively exemplarily described below with reference to fig. 2, where the ordinate of fig. 2 is the parameter amplitude change of each component to be controlled, and the abscissa is time.
High temperature sterilization stage
The control process of the indoor fan in the high-temperature sterilization stage is divided into a front stage and a rear stage, the indoor fan in the front stage is in a stop state, and at the moment, high-temperature refrigerant discharged by the compressor is input into the indoor heat exchanger to heat the indoor heat exchanger as soon as possible and reduce the loss of heat to the indoor environment, so that the indoor fan is controlled to be in the stop state; the indoor fan in the later stage is in a low-rotating-speed state (low-gear wind speed), the surface temperature of the indoor heat exchanger after the previous stage is close to or reaches the first sterilization temperature, and then the indoor fan is controlled to run at a low speed, so that heat can be conducted inside the indoor unit, the temperature of other parts of the indoor unit is increased, and the effect of performing high-temperature sterilization on other parts of the air conditioner is achieved.
Optionally, the front and rear stages of the indoor fan may be set to have a fixed time duration, for example, the time duration of the high-temperature sterilization stage is 35 minutes, the time duration of the front stage is set to be 5 minutes, and the time duration of the rear stage is set to be 30 minutes; therefore, the state switching of the indoor fan is controlled when the duration of each stage is counted and the duration requirement is met.
In some alternative embodiments, the switching between the first and second stages of the indoor fan may be determined based on the coil temperature.
When the air conditioner starts to execute the high-temperature sterilization stage of the step S101, detecting the temperature of the coil of the indoor heat exchanger through the temperature sensor in real time, and controlling the indoor fan to be in a shutdown state before the temperature of the coil does not reach a first sterilization temperature, wherein the indoor fan is in the shutdown state all the time in the previous stage; and after the temperature of the coil pipe reaches the first sterilization temperature, stage switching is carried out, and the indoor fan is switched to a low-rotation-speed state. Compared with the previous implementation mode of controlling according to fixed time, the two-stage state switching of the indoor fan can be realized more accurately, and the heating rate of the indoor heat exchanger and the sterilization effect of other parts of the indoor unit are guaranteed.
In still other alternative embodiments, the switching of the two stages of the indoor fan may be determined based on the initial frequency of the compressor. Here, the initial frequency of the compressor may affect the temperature of the refrigerant discharged therefrom, and thus, the temperature increase rate of the indoor heat exchanger and the time period required for switching the state of the indoor unit.
Illustratively, before the air conditioner performs the high-temperature sterilization stage of the step S101, acquiring an initial frequency of the compressor, and when the initial frequency is greater than a set frequency threshold, a duration of the first stage is a first duration; and when the initial frequency is less than or equal to the set frequency threshold, the duration of the first stage is a second duration, wherein the second duration is greater than the first duration. That is, the greater the initial frequency of the compressor is, the higher the temperature of the discharged refrigerant is, and the shorter the time required for the surface temperature of the indoor heat exchanger to reach the first sterilization temperature is. Therefore, the state switching of the indoor fan is controlled according to the initial frequency of the compressor, and the effects of accurately controlling and guaranteeing the heating rate can be achieved.
In some optional embodiments, the guide plate of the indoor unit is in a closed state or a slightly opened state during the high-temperature sterilization stage, so as to reduce the heat inside the indoor unit from escaping from the air outlet to the indoor environment. Optionally, in the heating condition, the guide plate of the indoor unit can be controlled to be opened at a slightly larger angle, so that part of refrigerant heat in the high-temperature sterilization process can be continuously conveyed to the indoor environment, and the uncomfortable influence on a user caused by the reduction of the indoor environment temperature in the cleaning process is avoided.
The parameters of the high-temperature sterilization stage comprise a first high-temperature sterilization parameter obtained according to the outdoor environment temperature, wherein the first high-temperature sterilization parameter comprises the rotating speed of a first outdoor unit of the outdoor fan and the first opening degree of the throttling device.
For the control of the outdoor fan in the high-temperature sterilization stage, the outdoor heat exchanger corresponding to the outdoor fan is in a heat absorption state, and the heat absorption efficiency of the outdoor heat exchanger can be influenced by the high and low heat exchange temperature difference between the outdoor environment temperature and the outdoor heat exchanger, so that the heating and temperature rising effects of the indoor heat exchanger are influenced; here, the outdoor environment temperature and the outdoor fan are in a negative correlation relationship, that is, the lower the outdoor environment temperature is, the larger the heat exchange temperature difference between the outdoor environment temperature and the outdoor heat exchanger is, and the larger the heat exchange air volume required for ensuring the heat absorption effect is. Therefore, the rotating speed of the outdoor fan is adjusted according to the outdoor environment temperature, so that the heat absorption efficiency of the outdoor heat exchanger is enhanced, and the high-temperature sterilization effect can be improved.
Optionally, the air conditioner is preset with a first association relationship between the outdoor environment temperature and the rotation speed of the external unit, where the first association relationship includes a one-to-one correspondence relationship between the outdoor environment temperature and the rotation speed of the external unit. Therefore, the rotating speed of the outdoor unit corresponding to the current outdoor environment temperature can be obtained by searching the association relation, and the outdoor fan is controlled to operate by taking the rotating speed of the outdoor unit as the rotating speed of the first outdoor unit.
In still other alternative embodiments, the frequency of the compressor can also affect the heat absorption efficiency of the outdoor heat exchanger. Here, the higher the operating frequency of the compressor is, the greater the amount of refrigerant discharged, and therefore the greater the amount of refrigerant flowing into the outdoor heat exchanger to exchange heat. Therefore, in this embodiment, the outdoor environment temperature and the frequency of the compressor are used together to determine the temperature of the outdoor fan in the high-temperature sterilization stage, and an optional corresponding relationship between the outdoor environment temperature Tao and the frequency f of the compressor and the external machine rotation speed of the outdoor fan is shown in table 1:
TABLE 1
| Outdoor ambient temperature/frequency | f＜60Hz | 60Hz≤f≤99Hz | f＞99Hz |
| Tao＜10℃ | 3 | 5 | 7 |
| 10≤Tao≤16℃ | 2 | 4 | 5 |
| Tao＞16℃ | 2 | 2 | 2 |
In this embodiment, the rotation speed gear of the outdoor fan is set to be 7 levels, and the rotation speed is increased in sequence; in the table 1, the rotation speed gear of the outdoor fan corresponding to different outdoor environment temperature and frequency combinations is shown, and in this embodiment, the rotation speed control of the outdoor fan in the high-temperature sterilization stage can be determined by looking up the table.
In some optional embodiments, the outdoor heat exchanger is in a heat absorption state, so the outdoor heat exchanger is also in a lower temperature state, and if the outdoor environment temperature is also in a lower temperature state, the outdoor heat exchanger is prone to frost formation, for example, when the cleaning method is operated under a heating working condition in winter, the outdoor environment temperature is very low, and the outdoor heat exchanger is prone to frost condensation gradually at a high-temperature sterilization stage, so that the heat absorption efficiency of the outdoor heat exchanger from the external environment is affected. Therefore, the control of the throttling device in the high-temperature sterilization stage mainly adjusts the opening degree of the throttling device according to the temperature condition of the outdoor environment; for example, the throttling device is adjusted at a higher opening degree when the outdoor environment temperature is lower, so that the refrigerant flowing into the outdoor heat exchanger from the indoor heat exchanger can also keep a higher temperature, and the frosting speed of the outdoor heat exchanger is delayed by utilizing the heat of the residual refrigerant; and when the indoor environment is lower, the throttling device is adjusted by a lower opening degree, so that the temperature and the pressure of the throttled refrigerant are lower, and the heat exchange efficiency of the refrigerant and the external environment is improved.
Optionally, the air conditioner is preset with a first association relationship between the outdoor ambient temperature and the opening degree of the throttling device, where the first association relationship includes a one-to-one correspondence relationship between the outdoor ambient temperature and the opening degree. Therefore, the opening corresponding to the current outdoor environment temperature can be obtained by searching the incidence relation, and the throttle device is controlled to be opened by taking the opening as the first opening. Table 2 shows the correlation between the outdoor ambient temperature and the opening degree of the throttle device in an alternative embodiment.
TABLE 2
| Outdoor environment temperature | Tao≥16 |
5℃≤Tao＜16℃ | Tao＜5℃ |
| Opening degree in high-temperature sterilization stage | 220 | 240 | 260 |
In this embodiment, the control of the opening of the restriction device during the autoclaving stage can thus be determined by looking up the table above.
In the embodiments, the outdoor unit of the air conditioner is provided with a temperature sensor, and the temperature sensor can be used for detecting and obtaining the outdoor environment temperature for acquiring the first high-temperature sterilization parameter.
In this embodiment, the high temperature sterilization phase further includes obtaining a second high temperature sterilization parameter according to the indoor coil temperature, where the second high temperature sterilization parameter includes a frequency of the compressor.
In some alternative embodiments, one of the keys of the high temperature sterilization stage is that the indoor heat exchanger can reach and maintain the first sterilization temperature, and since the high temperature refrigerant discharged from the compressor flows to the indoor heat exchanger first, the control of the compressor in the high temperature sterilization stage is mainly determined according to the coil temperature of the indoor heat exchanger.
Optionally, when the temperature of the coil pipe of the indoor heat exchanger is lower than the first sterilization temperature, the compressor is controlled to operate at a first frequency with a larger value, so that the amount and the temperature of a high-temperature refrigerant discharged into the indoor heat exchanger are increased, and the speed of raising the temperature of the indoor heat exchanger to the first sterilization temperature is accelerated; when the temperature of the coil pipe of the indoor heat exchanger is larger than or equal to the first sterilization temperature, the compressor is controlled to operate at a second frequency with the numerical value smaller than the first frequency, the problem that the indoor heat exchanger is heated continuously to trigger high-temperature protection can be avoided under the condition that the indoor heat exchanger is maintained at the first sterilization temperature, the operation power consumption of the compressor can be reduced, and the energy-saving and environment-friendly effects are achieved.
Here, the high temperature sterilization phase further comprises obtaining a frequency reduction rate of the compressor when the surface temperature of the target heat exchanger is greater than or equal to a set safe temperature threshold value according to the indoor coil temperature, and the set safe temperature threshold value is greater than the first sterilization temperature. Here, the safe temperature threshold is a critical value of the heat exchanger within a safe temperature range, when the current temperature of the heat exchanger exceeds the safe temperature range, the operation of the air conditioner is damaged, and a fault and a fire are easily caused.
The air conditioner is preset with a second incidence relation between the indoor coil temperature and the frequency reduction rate, and the preset second incidence relation comprises a corresponding relation between the indoor coil temperature and the frequency reduction rate. In an optional embodiment, the set safety temperature threshold is divided into three threshold steps (a first threshold, a second threshold and a third threshold), and the temperature values of the three threshold steps are gradually increased; when the temperature of the indoor coil is less than or equal to a first threshold value, the current running state of the heat exchanger is normal, and the current running frequency of the compressor is kept; when the temperature of the indoor coil pipe is greater than a first threshold value and less than or equal to a second threshold value, the heat exchanger is abnormal, and the compressor performs frequency reduction at a first frequency reduction rate with a smaller value; when the temperature of the indoor coil pipe is greater than a second threshold value and less than or equal to a third threshold value, the abnormal condition of the heat exchanger is serious, and at the moment, the compressor carries out frequency reduction at a second frequency reduction rate with the value greater than the first frequency reduction rate so as to accelerate the cooling operation of the heat exchanger and the output reduction operation of heat; when the temperature of the indoor coil pipe is larger than a third threshold value, the abnormal condition of the heat exchanger is serious, the compressor is controlled to stop at the moment, and the refrigerant is stopped from being input into the heat exchanger.
In some alternative embodiments, the four-way valve switches and maintains a valve position for the refrigerant to flow in a direction consistent with the heating mode during the autoclaving stage.
(II) quick cooling and sterilizing stage
The indoor fan operates at a rotating speed higher than that of the high-temperature sterilization stage in the quick-cooling sterilization stage, such as a medium-grade rotating speed, a high-grade rotating speed and the like; the refrigerant flows along the flow direction consistent with the refrigeration mode in the quick cooling sterilization stage, the refrigerant input into the indoor heat exchanger is a low-temperature refrigerant, the whole inside of the indoor unit is in a higher temperature state in the previous high-temperature sterilization stage, so that the temperature of the indoor heat exchanger can be reduced in a short time, and the effect of rapid cold and heat change of the temperature of the indoor heat exchanger is achieved.
In some embodiments not shown in the figures, the speed control of the indoor fan during the rapid cooling sterilization phase may also be determined based on the indoor coil temperature.
Illustratively, when the air conditioner starts to perform the rapid cooling sterilization stage of step S102, the real-time temperature sensor is used to detect the coil temperature of the indoor heat exchanger, the indoor fan is controlled to be in the middle-gear rotation speed state before the coil temperature is not reduced to the second sterilization temperature, and the indoor fan is switched to be in the low-rotation speed state or the shutdown state after the coil temperature is reduced to the second sterilization temperature. The control mode can improve the cooling and rapid cooling of the indoor heat exchanger in the rapid cooling and sterilization stage, and further improve the reinforced sterilization effect.
In some optional embodiments, in the quick cooling and sterilizing stage, the guide plate of the indoor unit is in a slightly opened state, so that the discharge of hot air of the indoor unit is accelerated, and the cooling and quick cooling are improved. Meanwhile, according to the difference of the current refrigeration and heating working conditions, the opening angle of the guide plate of the indoor unit can be further adjusted, if the refrigeration working conditions exist, the guide plate of the indoor unit can be controlled to be opened at a slightly larger angle, so that hot air can be discharged into the indoor environment more, and the utilization rate of waste heat in the high-temperature sterilization stage is improved; and in the refrigeration working condition, the guide plate of the indoor unit is controlled to supply air upwards so as to avoid the situation of a hot air direct blowing user and improve the use experience of the user.
The quick cooling sterilization stage comprises first quick cooling sterilization parameters obtained according to the outdoor environment temperature, wherein the first quick cooling sterilization parameters comprise a second external machine rotating speed of an outdoor fan and a first frequency of a compressor.
For the control of the outdoor fan in the rapid cooling and sterilization stage, the outdoor heat exchanger corresponding to the outdoor fan is in a heat release state, and the heat release efficiency of the outdoor heat exchanger can be influenced by the high and low heat exchange temperature difference between the outdoor environment temperature and the outdoor heat exchanger, so that the cooling and rapid cooling effects on the indoor heat exchanger are influenced; here, the outdoor environment temperature and the outdoor fan are in a positive correlation relationship, that is, the higher the outdoor environment temperature is, the smaller the heat exchange temperature difference between the outdoor environment temperature and the outdoor heat exchanger is, and the larger the heat exchange air volume required for ensuring the heat absorption effect is. Therefore, the rotating speed of the outdoor fan is adjusted according to the outdoor environment temperature, so that the heat dissipation efficiency of the outdoor heat exchanger is enhanced, and the quick cooling sterilization effect can be improved.
Optionally, a third correlation between the outdoor environment temperature and the rotation speed of the external unit is preset in the air conditioner, and the first correlation includes a one-to-one correspondence between the outdoor environment temperature and the rotation speed of the external unit. Therefore, the rotating speed of the outdoor unit corresponding to the current outdoor environment temperature can be obtained by searching the association relation, and the outdoor fan is controlled to operate by taking the rotating speed of the outdoor unit as the rotating speed of the second outdoor unit.
In still other alternative embodiments, the frequency of the compressor can also affect the heat rejection efficiency of the outdoor heat exchanger. Here, the higher the operating frequency of the compressor is, the greater the amount of refrigerant discharged, and therefore the greater the amount of refrigerant flowing into the outdoor heat exchanger to exchange heat. Therefore, in the present embodiment, the outdoor environment temperature and the frequency of the compressor are used together to determine the temperature of the outdoor fan in the quick cooling and sterilization stage, and an optional corresponding relationship between the outdoor environment temperature Tao and the frequency f of the compressor and the external machine rotation speed of the outdoor fan is shown in table 3:
TABLE 3
| Outdoor ambient temperature/frequency | f＜51Hz | 51Hz≤f≤80Hz | f＞80Hz |
| Tao＜22℃ | 2 | 3 | 5 |
| 22℃≤Tao≤29℃ | 3 | 6 | 7 |
| Tao＞29℃ | 7 | 7 | 7 |
In this embodiment, the setting of the gear position of the outdoor fan is the same as that in the previous embodiment, and in this embodiment, the control of the rotation speed of the outdoor fan in the rapid cooling sterilization stage can be determined by looking up the table.
In some alternative embodiments, one of the keys to the rapid cool sterilization phase is to lower and maintain the indoor heat exchanger below the second sterilization temperature for a short period of time; here at the rapid cooling sterilization stage, the compressor is because the high temperature refrigerant of compressor exhaust flows to outdoor heat exchanger earlier, then the outdoor ambient temperature height can influence the coolant at outdoor heat exchanger and outdoor environment's radiating efficiency, and then influences the refrigerant temperature that flows into indoor heat exchanger, then this application acquires the frequency of compressor according to outdoor ambient temperature for the compressor frequency after the adjustment can satisfy and cool down the requirement to second sterilization temperature rapidly with indoor heat exchanger.
Optionally, the third association further includes a one-to-one correspondence between the outdoor ambient temperature and the compressor frequency, so that the compressor frequency corresponding to the current outdoor ambient temperature can be obtained by searching the association.
For example, when the outdoor environment temperature is greater than the first outer ring temperature threshold, the compressor is controlled to operate at a third frequency with a larger value, so that the temperature and the quantity of the discharged refrigerant are increased, and the heat exchange efficiency of the refrigerant between the outdoor heat exchanger and the external environment is improved; when the outdoor environment temperature is lower than the first outer ring temperature threshold value, the heat exchange efficiency of the refrigerant and the outdoor environment is higher, the compressor is controlled to operate at a fourth frequency with the numerical value lower than the third frequency, and the power consumption of the compressor in the quick cooling sterilization stage can be effectively reduced.
In some optional embodiments, the rapid cooling sterilization phase further comprises a second rapid cooling sterilization parameter obtained according to the indoor ambient temperature, wherein the second rapid cooling sterilization parameter comprises a second opening degree of the throttling device. In this embodiment, the indoor fan in the quick cooling sterilization stage is operated at the middle-gear rotating speed, so the temperature of the indoor heat exchanger can be influenced to a certain extent by the indoor environment temperature, and therefore, in order to ensure the quick cooling sterilization effect, the opening degree of the throttling device is adjusted according to different temperature conditions of the indoor environment in this embodiment, so as to change the temperature and the pressure of the low-temperature refrigerant flowing into the indoor heat exchanger, and further reduce the adverse effect of the indoor environment temperature on the quick cooling sterilization effect.
Optionally, the air conditioner has a preset fourth association relationship, where the preset fourth association relationship includes a corresponding relationship between the indoor ambient temperature and the opening degree. Table 4 shows the correspondence between the ambient indoor temperature Tp and the opening degree of the throttle device in an alternative embodiment.
TABLE 4
| Indoor ambient temperature | Tp≥22℃ | Tp＜22℃ |
| Opening degree | 340 | 350 |
In this embodiment, therefore, the control of the opening degree of the throttle device for each stage of rapid cooling can be determined by looking up the table.
In some optional embodiments, when the operation of step S101 is performed, the electric auxiliary heating device may be further controlled to be activated to perform auxiliary heating, so as to accelerate the temperature rise inside the indoor unit by using the electric auxiliary heating device, and shorten a time period required by the indoor heat exchanger to reach the first sterilization temperature.
In some optional embodiments, after the high-temperature sterilization condition is met and before the rapid cooling sterilization is performed, because the refrigerant flow direction needs to be switched from the heating flow direction to the cooling flow direction, in order to ensure the stability of an internal system of the air conditioner in the switching process, the application controls to perform the pressure stabilizing operation, wherein the pressure stabilizing operation comprises that the throttling device is started at the maximum opening degree, the compressor is used for reducing the frequency, and the rapid cooling sterilization can be performed after the duration of the pressure stabilizing operation is determined to be greater than or equal to the set pressure stabilizing duration.
Optionally, the pressure stabilization time period is set to be 1-2 minutes.
In some optional embodiments, the method for air conditioning cleaning further comprises controlling activation of the ultraviolet sterilization device when the surface temperature of the target heat exchanger is heated to the first sterilization temperature. The ultraviolet sterilization device can utilize ultraviolet light to kill microorganisms in the indoor unit, thereby improving the overall sterilization effect.
