Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A control method of an air conditioner, a control device of an air conditioner, an electronic apparatus, and a computer-readable storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present application. In an embodiment of the present application, the air conditioner may be a split type air conditioner.
As shown in fig. 1, the method for controlling an air conditioner according to the embodiment of the present application includes the following steps:
s101, detecting the running frequency of the compressor, the temperature of a first coil of the indoor heat exchanger, the temperature of a second coil of the outdoor heat exchanger and the temperature of outdoor environment.
And S102, acquiring the target exhaust temperature of the compressor according to the operating frequency, the first coil temperature, the second coil temperature and the outdoor environment temperature.
The discharge temperature of the compressor is related to the operating frequency of the compressor, the coil temperature of the condenser, the coil temperature of the evaporator, and the outdoor ambient temperature. If the air conditioner is in a heating mode, the temperature of the first coil is the temperature of a coil of the condenser, and the temperature of the second coil is the temperature of a coil of the evaporator; if the air conditioner is in a refrigeration mode, the temperature of the second coil is the temperature of the coil of the condenser, and the temperature of the first coil is the temperature of the coil of the evaporator.
According to the principle of the refrigeration cycle of the air conditioner, if the operating frequency of the compressor is increased, or the temperature of a coil of the condenser is increased, or the temperature of a coil of the evaporator is reduced, the exhaust temperature of the compressor is increased.
Since the compressor is generally installed outdoors, the discharge temperature of the compressor is generally obtained by the temperature detection device, and the outdoor ambient temperature affects the accuracy of the temperature detection device, and the lower the outdoor ambient temperature is, the lower the discharge temperature of the compressor obtained by the temperature detection device is. For example, in severe cold weather, if the actual exhaust temperature of the compressor is 90 ℃, the exhaust temperature of the compressor acquired by the temperature detection device may be 85 ℃.
From the above analysis, in order to obtain a more accurate target discharge temperature, the target discharge temperature can be positively correlated with the operating frequency of the compressor, the coil temperature of the condenser, and the outdoor ambient temperature, respectively, and negatively correlated with the coil temperature of the evaporator. Optionally, the operating frequency of the compressor may be detected by collecting operating parameters of the air conditioner, for example, the operating frequency of the compressor may be determined by collecting voltage of the air conditioner, and the first coil temperature of the indoor heat exchanger and the second coil temperature of the outdoor heat exchanger may be detected by installing temperature detection devices on the coil pipe wall of the indoor heat exchanger and the coil pipe wall of the outdoor heat exchanger, respectively, and the outdoor environment temperature may be detected by installing a temperature detection device on an outdoor unit of the air conditioner or acquiring weather information through a wireless communication device, where the temperature detection device may be a temperature sensor.
Therefore, the method determines the target exhaust temperature of the compressor by detecting the operating frequency of the compressor, the coil temperature of the indoor heat exchanger, the coil temperature of the outdoor heat exchanger and the outdoor environment temperature, and can comprehensively consider the influence of the operating frequency of the compressor, the temperature of the indoor heat exchanger, the temperature of the outdoor heat exchanger and the outdoor environment temperature on the target exhaust temperature, so that the obtained target exhaust temperature is more accurate.
Optionally, a mapping relation or a mapping table between the target exhaust temperature and the operating frequency of the compressor, the first coil temperature, the second coil temperature, and the outdoor environment temperature may be pre-established, and after the operating frequency of the compressor, the first coil temperature, the second coil temperature, and the outdoor environment temperature are obtained, the mapping relation or the mapping table is queried, so that the target exhaust temperature currently required by the compressor can be determined. The mapping relationship or the mapping table may be preset in a storage space of the air conditioner, for example, may be stored in a main board of the air conditioner. It should be noted that the mapping relationship or the mapping table may be constructed according to different operation modes of the air conditioner, for example, the mapping relationship or the mapping table may be constructed when the air conditioner is in a heating mode or a cooling mode, respectively.
For example, a mapping function between the target discharge temperature and the operating frequency of the compressor, the first coil temperature, the second coil temperature, and the outdoor environment temperature may be established in advance, and after the operating frequency of the compressor, the first coil temperature, the second coil temperature, and the outdoor environment temperature are obtained, the obtained values are substituted into the mapping function, so as to obtain the target discharge temperature currently required by the compressor. The mapping function may be preset in a storage space of the air conditioner, for example, may be stored in a main board of the air conditioner. It should be noted that the mapping function may be constructed according to different operation modes of the air conditioner, for example, the mapping function may be constructed in a heating mode and a cooling mode of the air conditioner respectively.
And S103, acquiring the actual exhaust temperature of the compressor, and adjusting the opening of the throttling element in the air conditioner according to the actual exhaust temperature and the target exhaust temperature.
The actual exhaust temperature can be detected by installing a temperature detection device at the exhaust outlet pipe wall of the compressor, and the temperature detection device can be a temperature sensor. Wherein the throttling element may comprise an expansion valve.
The throttling element has the function of throttling and depressurizing, and the flow rate of the refrigerant can be adjusted by adjusting the opening degree of the throttling element, so that the actual exhaust temperature of the compressor can be adjusted.
For example, if the opening degree of the throttle element is decreased, the flow rate of the refrigerant decreases, and the high-low pressure side pressure difference of the air conditioner increases due to the principle of the refrigeration cycle, thereby increasing the discharge temperature of the compressor. When the opening degree of the throttle element is increased, the flow rate of the refrigerant is increased, and the high-low pressure side pressure difference of the air conditioner is decreased by the refrigeration cycle principle, thereby lowering the discharge temperature of the compressor.
Therefore, the method can actively adjust the opening degree of the throttling element according to the actual exhaust temperature and the target exhaust temperature so as to adjust the flow rate of the refrigerant, thereby actively adjusting the actual exhaust temperature of the compressor so as to approach the target exhaust temperature and improving the operation reliability of the air conditioner.
Optionally, the adjusting the opening degree of the throttling element may include acquiring an opening degree correction amount of the throttling element, and adjusting the opening degree of the throttling element according to the opening degree correction amount. The opening correction amount may be a positive or negative value, and the correction direction is to increase the opening of the restriction element if the opening correction amount is a positive value, and the correction direction is to decrease the opening of the restriction element if the opening correction amount is a negative value.
In one embodiment of the present application, the opening correction amount of the throttling element may be determined based on the deviation amount of the actual exhaust temperature and the target exhaust temperature. Wherein the deviation amount may be a difference or a ratio between the actual exhaust temperature and the target exhaust temperature.
If the absolute value of the difference is large, or the absolute value of the ratio is large relative to 1, it means that the deviation between the actual exhaust temperature and the target exhaust temperature is large, and in order to ensure the operation reliability of the air conditioner, the actual exhaust temperature needs to be adjusted greatly, and then the flow rate of the refrigerant needs to be adjusted greatly, and at this time, the absolute value of the opening correction amount of the throttling element should be large.
In one embodiment of the present application, the positive or negative of the opening correction amount of the throttling element may be determined according to the magnitude relation of the actual exhaust temperature and the target exhaust temperature.
If the obtained actual exhaust temperature is lower than the target exhaust temperature, the actual exhaust temperature is low, and in order to ensure the operation reliability of the air conditioner, the actual exhaust temperature is controlled to be increased, the opening degree of the throttling element is reduced to reduce the flow rate of the refrigerant, namely, the opening degree correction amount is a negative value. Further, according to the principle of the refrigeration cycle, the pressure difference between the high-pressure side and the low-pressure side of the air conditioner becomes large, and the discharge temperature of the compressor increases. If the obtained actual exhaust temperature is higher than the target exhaust temperature, the actual exhaust temperature is higher, and in order to ensure the operation reliability of the air conditioner, the actual exhaust temperature is controlled to be reduced, the opening degree of the throttling element is increased to increase the flow rate of the refrigerant, namely, the opening degree correction value is a positive value. Further, according to the principle of the refrigeration cycle, the difference in the high-and low-pressure side pressures of the air conditioner becomes small, and the discharge temperature of the compressor is lowered.
Alternatively, a mapping relation or a mapping table between the deviation amount and the opening correction amount of the throttling element may be established in advance, and after the deviation amount is obtained, the mapping relation or the mapping table is queried, so that the opening correction amount of the throttling element required by the air conditioner at the time can be determined. The mapping relationship or the mapping table may be preset in a storage space of the air conditioner, for example, may be stored in a main board of the air conditioner.
As another possible manner, a first difference between the actual exhaust gas temperature and the target exhaust gas temperature may be acquired, then a second difference between the actual exhaust gas temperature at the previous time and the actual exhaust gas temperature at the present time may be acquired, and the opening degree correction amount of the throttling element may be acquired based on the first difference and the second difference. In this map, the opening correction amount may be a negative value or a positive value, and in the case of a negative value, it corresponds to decreasing the opening and in the case of a positive value, it corresponds to increasing the opening, so that the actual exhaust temperature can be increased or decreased to approach the target exhaust temperature.
Therefore, the method can comprehensively consider the difference between the current exhaust temperature and the target exhaust temperature and the influence of the change of the actual exhaust temperature on the opening correction quantity of the throttling element, so that the obtained opening correction quantity is more accurate.
It should be noted that the first difference is a difference obtained by subtracting the actual exhaust temperature from the target exhaust temperature, and may be denoted as TPC, and the second difference is a difference obtained by subtracting the actual exhaust temperature at the previous time from the actual exhaust temperature at the current time, and may be denoted as △ TPC.
In one embodiment of the present application, a trend of change in the actual exhaust gas temperature may be identified based on a second difference between the actual exhaust gas temperature at the previous time and the actual exhaust gas temperature at the present time, and the opening correction amount of the throttling element may be obtained based on the trend of change and the first difference. The variation trend can be calibrated according to actual conditions, and can include an ascending trend, a descending trend and the like, and is preset in a storage space of the air conditioner, for example, the variation trend can be stored in a main board of the air conditioner.
Optionally, if the second difference is greater than or equal to the preset threshold and is a negative number, the actual exhaust temperature may be identified as an increasing trend, and if the second difference is greater than or equal to the preset threshold and is a positive number, the actual exhaust temperature may be identified as a decreasing trend. The preset threshold value can be calibrated according to actual conditions, and is preset in a storage space of the air conditioner, for example, the preset threshold value can be stored in a main board of the air conditioner.
Further, acquiring the opening correction amount of the throttling element according to the variation trend and the first difference value, which may include determining a target correction direction of the actual exhaust temperature and the first opening correction amount of the throttling element according to the first difference value, then identifying whether the variation trend of the actual exhaust temperature is consistent with the target correction direction of the actual exhaust temperature, if the variation trend is consistent with the correction direction, reducing the absolute value of the first opening correction amount to avoid over-adjustment, and taking the updated first opening correction amount as the opening correction amount; if the change tendency does not coincide with the correction direction, the absolute value of the first opening degree correction amount may be increased and the updated first opening degree correction amount may be used as the opening degree correction amount in order to increase the adjustment speed. Wherein the target correction direction includes decreasing or increasing the actual exhaust temperature.
The method can actively adjust the preset opening correction according to whether the variation trend of the actual exhaust temperature is consistent with the target correction direction or not, can avoid excessive adjustment, and can accelerate the adjustment speed and efficiency.
For example, a mapping relation or a mapping table between the opening correction amount of the throttling element and the first difference may be established in advance, after the first difference is obtained, the mapping relation or the mapping table may be queried, so as to determine the first opening correction amount, then the change trend of the actual exhaust temperature may be identified according to the second difference, if the change trend is an increasing trend, the target correction direction of the actual exhaust temperature determined according to the first difference is to decrease the actual exhaust temperature, which indicates that the change trend is not consistent with the target correction direction, and in order to accelerate the decrease of the actual exhaust temperature, the absolute value of the first opening correction amount may be increased.
As another possible implementation manner, a mapping relation or a mapping table between the opening correction amount of the throttling element and the first difference and the second difference may be established in advance, and after the first difference and the second difference are obtained, the mapping relation or the mapping table is queried, so that the opening correction amount of the throttling element required at this time can be determined. The mapping relationship or the mapping table may be preset in a storage space of the air conditioner, for example, may be stored in a main board of the air conditioner.
For example, as shown in table 1, a mapping table between the opening correction amount of the throttle element and the first difference (TPC) and the second difference (△ TPC) may be established in advance.
