It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the present disclosure described herein may be made. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.

In the embodiment of the present disclosure, the character "/" indicates that the preceding and following objects are in an or relationship. For example, A/B represents: a or B.
The term "and/or" is an associative relationship that describes objects, meaning that three relationships may exist. For example, a and/or B, represents: a or B, or A and B.
In the field of air conditioning, the general target exhaust temperature is set in advance according to experimental data and a common ambient temperature range, so that adaptability change cannot be made according to actual ambient conditions, and the air conditioner operation effect is weakened. For example, when the ambient temperature is low and the air conditioner heats, if the target exhaust temperature is not adjusted, the air conditioner will frequently defrost, resulting in fluctuation of the indoor temperature. In order to stabilize the operation of the air conditioning unit system, adaptive adjustment of the target exhaust temperature is required.
The following disclosed embodiments are all satisfied based on the condition that the air conditioner is in a low-temperature environment for heating.
Based on this, as shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, the method including:
and step S01, after the exhaust temperature of the compressor is determined to reach the target exhaust temperature, continuously acquiring the new exhaust temperature of the compressor.
Here, the discharge temperature refers to an actual discharge temperature of the compressor; the new exhaust temperature refers to the changed actual exhaust temperature. For how to collect the actual exhaust temperature, reference may be made to related technologies, which are not described herein.
The method for acquiring the exhaust temperature of the compressor may be acquiring the actual exhaust temperature according to a preset sampling period, or acquiring the actual exhaust temperature in real time, which is not limited herein.
And step S02, determining the current exhaust temperature change rate corresponding to the new exhaust temperature collected in the current control period according to the preset control period.
Here, the preset control period is preset to express that the exhaust temperature change rate is calculated every time one preset control period passes; the current control period refers to a period in which a time when a new exhaust temperature is collected falls according to a time length of a preset control period.
In step S03, a current correction value corresponding to the current exhaust temperature change rate is determined based on the correspondence relationship between the exhaust temperature change rate and the target exhaust temperature correction value.
Here, the current correction value is used to express the adjustment amount of the current target exhaust gas temperature.
Alternatively, determining a current correction value corresponding to the current exhaust temperature change rate according to the correspondence between the exhaust temperature change rate and the target exhaust temperature correction value includes: if a is less than or equal to K and less than b, T is-10 abb; if b is less than or equal to K and less than c, T is-10 × c; if c is less than or equal to K and less than d, T is-10 x d; if d is less than or equal to K and less than e, T is-10 × e; where K is the exhaust gas temperature change rate, T is the target exhaust gas temperature correction value, a ranges from 0 to 0.1, b ranges from 0.1 to 0.5, c ranges from 0.6 to 1, d ranges from 1 to 1.5, and e ranges from 1.5 to 2.
As such, the larger the exhaust temperature change rate, the larger the target exhaust temperature correction value. The large exhaust temperature change rate indicates that the difference between the actual exhaust temperature and the target exhaust temperature is large, the target exhaust temperature needs to be reduced, and at the moment, the target exhaust temperature correction value is large, so that the difference between the corrected target exhaust temperature and the current latest exhaust temperature can be reduced.
Here, a, b, c, d, and e are random numbers that take values within the respective intervals.
In some embodiments, when a is 0.04, b is 0.2, c is 0.7, d is 1.2, and e is 1.8, and when the current exhaust temperature change rate K is 0.6, which is greater than b and less than c, the corresponding correction value T is-10 × 0.7 is-7, that is, the target exhaust temperature is decreased by 7 degrees celsius.
In still other embodiments, a is 0.06, b is 0.3, c is 0.8, d is 1.4, and e is 1.7, and when the current exhaust temperature change rate K is 0.2, which is greater than a and less than b, the corresponding correction value T is-10, 0.3 is-3, that is, the target exhaust temperature is decreased by 3 degrees celsius.
Optionally, the control method further includes:
in the case where the current exhaust temperature change rate is greater than or equal to the preset change rate, the correspondence between the exhaust temperature change rate and the target exhaust temperature correction value is acquired.
Here, the preset change rate is used to express a case where the value of the exhaust gas temperature changes in one control cycle. When the exhaust temperature change rate is smaller than the preset change rate, the exhaust temperature change rate is smaller, and the difference between the actual exhaust temperature and the target exhaust temperature is not large; when the exhaust temperature change rate is greater than or equal to the preset change rate, the exhaust temperature change rate is relatively large, and the actual exhaust temperature has a large difference from the target exhaust temperature. In the embodiment of the present disclosure, the value of the preset rate of change may be the value of a in the embodiment of the present disclosure, where a ranges from 0 to 0.1.
Therefore, when the difference between the actual exhaust temperature and the target exhaust temperature is not large, the problem that frequent defrosting of the air conditioner causes large fluctuation of the indoor temperature is avoided, the target exhaust temperature does not need to be corrected, the exhaust temperature adjusting process can be simplified, and the power consumption is reduced.
And step S04, correcting the target exhaust temperature according to the current correction value so as to reduce the difference between the corrected target exhaust temperature and the latest exhaust temperature collected in the current control period.
Optionally, the control method further includes: the correction of the target exhaust gas temperature is stopped in a case where the heat exchanger defrosting condition is satisfied or the valve opening degree of the throttle element is adjusted to the maximum opening degree.
Here, the throttling element refers to an element that can adjust the valve opening degree, and in the embodiment of the present disclosure, the throttling element may be an electronic expansion valve.
Thus, under the condition that the defrosting condition of the heat exchanger is met, the air conditioner starts defrosting, and the correction of the target exhaust temperature is no longer meaningful; when the valve opening degree of the throttling element is adjusted to the maximum opening degree, the target exhaust gas temperature cannot be continuously decreased, and therefore, the correction of the target exhaust gas temperature is stopped.
Optionally, if the new exhaust temperature of the compressor is collected according to a preset sampling period, the preset sampling period is smaller than a preset control period, and the preset control period is an integer multiple of the preset sampling period, the correcting of the target exhaust temperature is stopped when the valve opening of the throttling element is adjusted to the maximum opening, including: determining the current valve opening corresponding to the latest exhaust temperature according to the latest exhaust temperature acquired under the current sampling period; and stopping correcting the target exhaust gas temperature if the current valve opening is the maximum opening of the throttling element.
Therefore, the detection frequency of the exhaust temperature is high, whether the opening degree of the valve reaches the maximum opening degree or not can be known according to the detected real-time exhaust temperature, the target exhaust temperature is stopped to be corrected in time, and the power consumption is reduced.
Alternatively, the stopping of the correction of the target exhaust gas temperature in the case where the heat exchanger defrosting condition is satisfied includes: determining a corresponding defrosting condition at the current environment temperature; and stopping correcting the target exhaust temperature under the condition that the temperature of the outdoor unit coil meets the defrosting condition.
In this way, when the heat exchanger is defrosted, the air conditioner stops heating, and at this time, the target exhaust temperature does not need to be corrected.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the difference between the actual exhaust temperature and the target exhaust temperature can be obtained by acquiring the exhaust temperature and the exhaust temperature change rate; determining a target exhaust temperature correction value according to the numerical value interval of the exhaust temperature change rate, so as to reduce the difference between the actual exhaust temperature and the target exhaust temperature; and adjusting the target exhaust temperature of the air conditioner according to the target exhaust temperature correction value. Through the scheme, the target exhaust temperature can be corrected, so that the condition that the indoor temperature fluctuates due to frequent defrosting of the air conditioner is avoided, the air conditioning unit system is stable in operation, the air conditioner is good in heating effect, and the user experience is good.
Fig. 2 is a flowchart of a control method for an air conditioner according to an embodiment of the present disclosure. As shown in fig. 2, the control method for an air conditioner includes:
and step S11, collecting the compressor exhaust temperature after a set time as the new exhaust temperature of the compressor when the exhaust temperature of the compressor reaches the target exhaust temperature.
Here, the set time period is a time length set in advance and used to express a time during which a state in which the exhaust gas temperature change rate is small continues. When the set length is not reached, the change rate of the exhaust temperature is relatively small, and the target exhaust temperature is not corrected; after a set time period, the exhaust gas temperature change rate is relatively large, and a numerical value of the exhaust gas temperature change rate needs to be obtained according to the collected exhaust gas temperature, so that the target exhaust gas temperature is corrected.
In the embodiment of the disclosure, the setting of the set duration may refer to experimental data under typical working conditions in the development stage.
And step S12, determining the current exhaust temperature change rate corresponding to the new exhaust temperature collected in the current control period according to the preset control period.
In step S13, a current correction value corresponding to the current exhaust temperature change rate is determined based on the correspondence relationship between the exhaust temperature change rate and the target exhaust temperature correction value.
And step S14, correcting the target exhaust temperature according to the current correction value so as to reduce the difference between the corrected target exhaust temperature and the latest exhaust temperature collected in the current control period.

Through the embodiment of the disclosure, the target exhaust temperature can be corrected, so that the air conditioning unit system is stable in operation, the air conditioning heating effect is good, unnecessary correction times can be reduced, and the adjusting process is simplified.

In step S23, the magnitude relationship between the current exhaust temperature change rate and the preset change rate is determined.
In step S24, the target exhaust temperature is not corrected in the case where the current exhaust temperature change rate is smaller than the preset change rate.
In step S25, in the case where the current exhaust temperature change rate is greater than or equal to the preset change rate, the current correction value is determined based on the correspondence between the exhaust temperature change rate and the target exhaust temperature correction value.
And step S26, correcting the target exhaust temperature according to the current correction value so as to reduce the difference between the corrected target exhaust temperature and the latest exhaust temperature collected in the current control period.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, the difference between the actual exhaust temperature and the target exhaust temperature can be obtained by acquiring the exhaust temperature and the exhaust temperature change rate; by judging the magnitude relation between the current exhaust temperature change rate and the preset change rate, the target exhaust temperature is corrected under the condition that the current exhaust temperature change rate is greater than or equal to the preset change rate, so that the adjustment process can be simplified; determining a target exhaust temperature correction value according to the numerical value interval of the exhaust temperature change rate, so as to reduce the difference between the actual exhaust temperature and the target exhaust temperature; and adjusting the target exhaust temperature of the air conditioner according to the target exhaust temperature correction value.
