According to an aspect of an embodiment of the present application, there is provided an air conditioner control method. Alternatively, in the present embodiment, the air conditioner control method described above may be applied to a hardware environment as shown in fig. 1. As shown in figure 1 of the drawings, in which,
according to an aspect of an embodiment of the present application, there is provided an air conditioner control method. Alternatively, in the present embodiment, the air-conditioning control method described above may be applied to a hardware environment constituted by the terminal 102 and the server 104 as shown in fig. 1. As shown in fig. 1, the server 104 is connected to the terminal 102 through a network, which may be used to provide services for the terminal or a client installed on the terminal, may be provided with a database on the server or independent from the server, may be used to provide data storage services for the server 104, and may also be used to handle cloud services, and the network includes but is not limited to: the terminal 102 is not limited to a PC, a mobile phone, a tablet computer, etc. the terminal may be a wide area network, a metropolitan area network, or a local area network. The air conditioner control method in the embodiment of the present application may be executed by the server 104, may be executed by the terminal 102, or may be executed by both the server 104 and the terminal 102. The terminal 102 may execute the air conditioner control method according to the embodiment of the present application by a client installed thereon.
Taking the terminal 102 and/or the server 104 to execute the air conditioning control method in this embodiment as an example, fig. 2 is a schematic flowchart of an optional air conditioning control method according to an embodiment of the present application, and as shown in fig. 2, the flowchart of the method may include the following steps:
step S202, acquiring outdoor environment temperature, relative humidity and air conditioner outer tube temperature;
step S204, calculating real-time dew point temperature based on the outdoor environment temperature and the relative humidity;
step S206, calculating the temperature difference between the real-time dew point temperature and the temperature of the outer pipe of the air conditioner;
step S208, accumulating the first frosting degree corresponding to the temperature difference value larger than the first preset value to obtain an accumulated frosting degree, wherein the first frosting degree is obtained based on the difference value and the preset time length;
and step S210, controlling the air conditioner to enter a defrosting mode when the accumulated frosting degree is greater than a preset frosting degree.
Through the steps S202 to S210, in the air conditioner heating operation process, the outdoor temperature, the outdoor relative humidity and the air conditioner appearance temperature are obtained in real time, the dew point temperature is calculated based on the outdoor temperature and the outdoor relative humidity, the dew point temperature is compared with the air conditioner outer tube temperature, the difference values meeting the conditions are accumulated to obtain the air conditioner frosting degree, when the air conditioner frosting degree meets the preset conditions, the air conditioner is judged to enter defrosting control, in the air conditioner frosting dynamic process, the real-time operation is performed, the frosting condition of the air conditioner is judged, and therefore the air conditioner is subjected to defrosting control when the air conditioner frosting layer is thick. Therefore, the defrosting is accurately realized, the defrosting control is not performed when no frost exists, the defrosting process is performed after the frosting is ensured to a certain degree, and the heating efficient operation of the air conditioning unit can be ensured.
For the technical solution in step S202, the outdoor unit air temperature and the outdoor side relative humidity can be detected in real time, in this embodiment, the detection can be performed by the temperature and humidity sensor of the outdoor unit, and the third-party weather data collected by the APP associated with the air conditioner can also be used. For example by acquiring meteorological data at a meteorological station. In this embodiment, the air conditioner is a heat pump type air conditioner, and supplies heat to the room in cold seasons. The heat exchange is carried out through the air conditioner outer pipe, after the air conditioner runs for a period of time, the surface of the heat exchanger of the outdoor unit is prone to frosting, the surface temperature of the heat exchanger can be approximately regarded as the evaporation temperature of a refrigerant, namely the temperature of a coil of the outdoor unit, the temperature of the air conditioner outer pipe is called as the temperature of the air conditioner outer pipe for short, and therefore the temperature value of the air conditioner outer pipe can be obtained through the temperature sensor in real time.
For the technical solution in step S204, the real-time dew point temperature is calculated based on the outdoor environment temperature and the relative humidity, and the evaporation temperature of the air conditioner and the dew point temperature of the outdoor air jointly determine the difficulty of frosting and the actual frosting condition. When the air pressure is kept constant with the water vapor content in the air unchanged, the temperature at which the air is cooled to saturation is called the dew point temperature, and usually 0 ℃ or higher is called the "dew point" and 0 ℃ is called the "frost point" hereinafter. The embodiment is used for air conditioner defrosting control, so the dew point temperature is usually a subzero temperature value. As an exemplary embodiment, the dew point temperature value of the air may be calculated from the following equation according to the relative humidity and the temperature value.
LogEW＝(0.66077+7.5*T/(237.3+T)+(log10(RH)－2)
From the formula, Td ((0.66077-logEw) × 237.3)/(logEw-8.16077), it can be seen that the dew point value is mainly related to the relative humidity and temperature, and is changed by the changes of them. The unit of the outdoor temperature T and the dew point temperature Td is centigrade, the relative humidity RH is percentage, and the Ew is the liquid level saturated vapor pressure corresponding to the temperature T.
And for the technical scheme in the step S206, calculating the temperature difference between the real-time dew point temperature and the temperature of the air conditioner outer pipe. As an exemplary embodiment, the temperature and humidity of the outdoor environment have a great influence on the frosting amount of the heat pump air conditioner. The outdoor heat exchanger surface temperature and the dew point temperature of the air blown over the heat exchanger surface together determine the frosting condition. When the surface temperature of the heat exchanger is lower than zero and the dew point temperature of air, frost formation can occur. When the air conditioning product is operated for heating, the larger the difference between the surface temperature and the dew point temperature of the heat exchanger is, the higher the frosting speed is. The heat exchanger surface temperature can be approximately regarded as the refrigerant evaporation temperature (air conditioner outer tube temperature). The evaporation temperature of the air conditioner and the dew point temperature of the outdoor air jointly determine the difficulty degree of frosting and the actual frosting condition. Therefore, the temperature difference between the real-time dew point temperature and the temperature of the outer pipe of the air conditioner can be calculated to serve as the basis of the frosting amount, and therefore whether the real-time dew point temperature is smaller than a second preset value or not is judged; when the real-time dew point temperature is smaller than a second preset value, judging whether the temperature difference value is larger than a first preset value or not; and when the temperature difference is larger than the first preset value, accumulating the first frosting degree corresponding to the temperature difference larger than the preset value. For example, it is determined whether the dew-point temperature Td satisfies the condition that Td is less than or equal to 0 ℃, and if yes, the dew-point temperature Td is compared with the real-time outer tube temperature Te, and the temperature difference Δ T is Td-Te, when Δ T is greater than a first preset value, frost may be formed on the outer tube of the outdoor unit or the surface of the heat exchanger, for example, if Δ T is Td-Te is greater than or equal to 0 ℃, the outer tube temperature of the outdoor unit is lower than the dew-point temperature, and Td is lower than 0 ℃. Indicating that in this case, frosting occurs.
For the technical scheme in step S208, when the temperature difference Δ T is greater than the first preset value, accumulating the first frosting degree corresponding to the temperature difference greater than the first preset value to obtain an accumulated frosting degree, where the first frosting degree is obtained based on the difference and the preset time length. As an exemplary embodiment, in the present embodiment, the frosting degree may be a thickness of frosting, an area of frosting, and other characteristics, that is, a size for representing the frosting amount or a difficulty level of removing frosting. When the temperature difference value meets the condition, namely is larger than a first preset value, the frosting degree in the preset time length is accumulated once every preset time length, the frosting degree in the preset time length is determined based on different working conditions, and in particular, the frosting can occur in about 50-80 min in common frosting weather.
As an exemplary embodiment, there is a prior art that the temperature difference Δ T is averaged, the defrosting mode is determined based on the average value of the temperature difference Δ T, and the average value of the temperature difference over a period of time is used as an index of the frost formation degree to weaken the influence of the variation range of the temperature difference. For example, if the air conditioner frosts more and the temperature difference Δ T becomes larger due to weather reasons at a certain moment in the heating operation of the air conditioner, the average value will increase, and if Δ T is decreased due to weather changes or operation changes of the air conditioning system, the new average value will show a gradually decreasing trend. While the actual frost thickness is continuously increasing. The calculated frosting degree is inaccurate, so that the thickness condition of a frost layer cannot be effectively indicated, and the frosting degree is accumulated to control the defrosting of the air conditioner, so that the condition of the frosting degree can be reflected in real time, and the defrosting can be more accurately performed.
As an exemplary embodiment, the preset time Δ t generally has a value range as follows: delta t is more than or equal to 30s and less than or equal to 600s, the time interval is too short, and the controller has more execution operation data; the time interval is too long to feed back the frosting condition in time. Therefore, the first frost degree corresponding to the temperature difference value larger than the preset value needs to be accumulated to obtain an accumulated frost degree, and whether defrosting is needed or not is determined based on the accumulated frost degree, for example, the accumulated frost degree may be: judging whether the temperature difference value is larger than a first preset value or not; when the temperature difference is larger than the first preset value, calculating the frosting degree within a preset time length as the first frosting degree under the current temperature difference; and accumulating the first frosting degrees in a plurality of preset time lengths corresponding to the temperature difference values larger than the first preset value according to a time sequence to obtain the accumulated frosting degrees.
In the present embodiment, the preset time Δ t may take 60S as an example. And when the accumulated frosting degree is greater than the preset frosting degree, controlling the air conditioner to enter a defrosting mode. Specifically, the preset duration is a fixed value, the preset frosting degree is the same value, under different frosting working conditions, the time for reaching the value is different, the frosting working condition is easy to occur, the frosting working condition is reached earlier, the defrosting is started earlier, the frosting working condition is not easy to occur, and the defrosting is started later when the frosting working condition is reached later. The defrosting can be realized at proper time under all working conditions. The preset frosting degree is determined based on the preset time length and an outdoor environment factor, and the outdoor environment factor is determined based on the outdoor environment temperature and the relative humidity.
In order to enable the preset frosting degree fixed value to have strong adaptability.
Presetting the frosting degree based on a preset time delta t, and influenced by a coefficient xi; specifically, the preset time duration Δ t is different, and the accumulated frost degree accumulation result is also different, for example, when the air conditioner reaches a severe frost degree in the 60 th min, the FD value is different between the time when the sampling Δ t is 30S and the time when the sampling Δ t is 60S, and thus the FD preset value is different.
More recently, the coefficient ξ may be preset according to different outdoor environment dimensions and relative humidity, specifically, see table 1, where ξ FD preset value ξ FD standard value × Δ t standard value/Δ t, preferable Δ t standard value 60s, FD frosting degree, and FD preset value preset frosting degree.
TABLE 1
1-1 is not more than 1 and not more than 1-2 is not more than 1-3; xi 1-1 takes the value of [ 0.6-1.0 ]; xi 1-2 takes the value of [ 0.8-1.2 ]; xi 1-3 value [ 1-3 ]
Xi 2-1 is not more than xi 2-2 is not more than xi 2-3; xi 2-1 takes a value of [ 0.6-1.1 ]; xi 2-2 takes a value of [ 0.8-1.2 ]; xi 2-3 value [ 1-3 ]
Xi 3-1 is less than or equal to xi 3-2; xi 2-1 takes a value of [ 1-3 ]; xi 2-2 takes the value of [ 1-4 ];
ξ1-1≤ξ2-1≤ξ3-1
ξ1-2≤ξ2-2≤ξ3-2
because the T outer ring is more than 5.8 ℃ and the T outer ring is less than or equal to minus 12.8 ℃ regardless of the relative humidity, the two intervals are in the working condition of no frosting, so the method has the advantages of simple structure, low cost and high safety
Xi 0 takes the value of [ 1-50 ].
And when the FD is judged not to meet the condition, judging that the accumulated operation time of the frosting degree calculation method is met, and when the accumulated operation time reaches a preset value, judging that the air conditioner enters defrosting control. When the accumulated frosting degree is smaller than a preset frosting degree, counting the accumulated time length of which the temperature difference value is larger than the first preset value; and when the accumulated time length is longer than the preset accumulated time length, controlling the air conditioner to enter a defrosting mode. The preset accumulation period is determined based on the outdoor ambient temperature and the relative humidity.
And (3) judging the time meeting the conditions that Td is less than or equal to 0 ℃ and delta T is greater than or equal to Td-Te and is greater than or equal to 0 ℃, timing T0, judging that the accumulated time is greater than the preset accumulated time, if the accumulated time is not greater than the preset accumulated time, continuously calculating FD, and if the conditions are met, entering defrosting control.
Wherein the value of t0 is determined between the outer ring and the humidity partition
Based on the difference between the outer ring and the interval, t is preset to be 1 ═ δ t standard value, specifically see table 2:
TABLE 2
Delta 1-1 is more than or equal to delta 1-2 is more than or equal to delta 1-3; delta 1-1 takes the value of [ 0.5-1.0 ]; delta 1-2 takes the value of [ 0.8-1.2 ]; delta 1-3 takes the value of [ 1-5 ];
delta 2-1 is more than or equal to delta 2-2 is more than or equal to delta 2-3; delta 2-1 takes the value of [ 0.6-1.1 ]; delta 2-2 takes the value of [ 0.8-1.5 ]; delta 2-3 takes the value of [ 1-6 ];
delta 3-1 is not more than delta 3-2; delta 2-1 takes the value of [ 1-5 ]; delta 2-2 takes the value of [ 1-10 ];
δ1-1≤δ2-1≤δ3-1；
δ1-2≤δ2-2≤δ3-2；
because the T outer ring is more than 5.8 ℃ interval (the outer ring temperature is high) and the T outer ring is less than or equal to minus 12.8 ℃ (the moisture content is low), no matter what the relative humidity is, the two intervals are the frostless working condition, so the time threshold value protection measure is not set.
Determining whether delta T is Td-Te
T outer ring is greater than 5.8 deg.C: Δ T > Δ T1; delta T1 value [5 ℃,10 ℃) ]
The temperature of T outer ring is less than or equal to minus 12.8 ℃, and delta T is more than delta T2; delta T2 value [5 ℃,10 ℃) ]
As an exemplary embodiment, when the defrosting time of the air conditioner is in different intervals, the previous frosting degree preset value is automatically adjusted, so that the time for the next air conditioner to enter the defrosting control is in a reasonable frosting thickness of the air conditioner. Specifically, the time interval from the start of defrosting to the end of defrosting is obtained; when the interval duration is in a first preset interval, keeping the preset frosting degree unchanged; when the interval length is in a second preset interval, reducing the preset frosting degree; and when the interval duration is in a third preset interval, increasing the preset frosting degree, wherein the minimum value of the second preset interval is greater than or equal to the maximum value of the first preset interval, and the maximum value of the third preset interval is less than or equal to the minimum value of the first preset interval. For example, the time interval from the start of defrosting to the end of defrosting can be the time interval from the moment of starting defrosting to the time interval when the temperature of the outer pipe reaches 0 ℃ or more than 0 ℃, when the air conditioner is applied at home, the air conditioner enters defrosting when the FD is not less than the preset value FD, and the time ts from the start of defrosting to the end of defrosting is recorded; judging ts0 is more than ts and less than or equal to ts 1; if yes, continuing to judge next defrosting according to the original FD preset value, if ts is larger than ts1, indicating that the defrosting time is too long (frost layer thickness), subtracting a value from the FD preset value on the original basis, and obtaining the FD preset value-delta FD; if ts is less than or equal to ts0, the defrosting time is too short (frost layer is light), and the FD preset value + delta FD is obtained; thereby realizing the self-adaptive control in the defrosting process. Illustratively, the first preset interval may be [ ts0, ts 1], the second preset interval may be greater than ts1, and the third preset interval may be less than ts0, wherein ts1 is less than or equal to 8min and less than or equal to 12min and ts0 is less than or equal to 8 min. For example, see the adaptive adjustment measures shown in table 3:

| Defrosting time ts | FD Preset value |
| ts＞ts1 | Preset value of FD- Δ FD |
| ts0＜ts≤ts1 | FD Preset value |
| ts≤ts0 | FD Preset value + Δ FD |
