On the premise of not changing hardware of an outdoor unit or increasing cost, the reliability of the air conditioner outdoor unit is difficult to guarantee during high-temperature work.
In view of the above problems, no effective solution has been proposed.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

In accordance with an embodiment of the present invention, there is provided a method embodiment of a control method of an air conditioner, it is noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Example one
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring a temperature value of the outdoor environment.
Specifically, the obtaining of the outdoor environment temperature of the outdoor unit of the air conditioner may be a real-time monitoring of the temperature by using a temperature sensing pack installed on the outdoor unit of the air conditioner, and obtaining an outdoor temperature value transmitted by the temperature sensing pack to the air conditioner processor, where the temperature value is used as a precondition for subsequently determining how to limit the current.
And step S104, determining a current limit value of a compressor of the air conditioner according to the temperature value of the outdoor environment.
Specifically, after determining the temperature value of the outdoor unit of the air conditioner, the air conditioner processor needs to determine the current limit value of the compressor according to the relationship between the current limit value and the external ambient temperature as shown in fig. 2, which is used as a basis for subsequently judging the working current and whether to start the limiting operation of the compressor.
Optionally, determining the current limit value of the compressor of the air conditioner according to the temperature value of the outdoor environment includes: acquiring a corresponding relation between a temperature value of an outdoor environment and a current limit value to obtain a first corresponding relation; and obtaining a current limit value according to the first corresponding relation.
Specifically, as shown in fig. 2, different ambient temperature values of the outdoor unit of the air conditioner correspond to different current limit values, that is, in the case of an increasing outdoor temperature, the current is set to different limit values according to a changing temperature, so as to ensure that the outdoor unit of the air conditioner does not cause a compressor failure due to a high temperature during the operation.
Optionally, determining the current limit value of the compressor of the air conditioner according to the temperature value of the outdoor environment includes: determining a temperature range to which a temperature value of the outdoor environment belongs; and determining a current limit value of a compressor of the air conditioner according to the temperature range.
Optionally, before determining the current limit value of the compressor of the air conditioner according to the temperature range, the method further comprises: acquiring a corresponding relation between the temperature range and the current limit value to obtain a second corresponding relation; and obtaining a current limit value according to the second corresponding relation.
Specifically, in the method for determining the current limit value according to the embodiment of the present invention, the current limit value may be determined according to an outdoor temperature range of the outdoor unit of the air conditioner, so that a relationship graph between the current limit value and the external ambient temperature during actual control may also be as shown in fig. 3 and 4. If the system has high requirement on the control precision and strong calculation capability, a quadratic function relation graph shown in fig. 3 can be adopted, and the current limit value determined by adopting the relation is most accurate, so that the performance of the system can be increased to the maximum extent on the premise of ensuring the reliability of the system. If the system has low precision requirement or insufficient calculation capacity, a sectional type relation graph shown in FIG. 4 can be adopted to determine a fixed current limit value according to different temperature intervals, and the current limit value determined by the method can ensure the reliable operation of the system and save the calculation capacity of the system.
And step S106, comparing the current limit value with the current value of the current work of the compressor to obtain a comparison result.
Specifically, after the air conditioning processor obtains the current limit value according to the ambient temperature of the air conditioning outdoor unit, the working current value of the compressor needs to be detected according to a current real-time detection device arranged on the air conditioning compressor, and after the current value of the compressor during working is obtained, the obtained working current value and the current limit value need to be compared, and a comparison result is obtained, wherein the comparison result may be that the current limit value is smaller than the working current value, or the current limit value is not smaller than the working current value.
And step S108, controlling the running frequency of the compressor according to the comparison result.
Optionally, controlling the operating frequency of the compressor according to the comparison result includes: if the comparison result is that the current limit value is not less than the current value of the current work of the compressor, controlling the current running frequency of the compressor to be unchanged; if the comparison result is that the current limit value is smaller than the current value of the current work of the compressor, the running frequency of the compressor is reduced until the current limit value is not smaller than the current value of the current work of the compressor.
Specifically, according to the comparison result between the working current value and the current limit value, if the comparison result is that the current limit value is not less than the current value of the current work of the compressor, it indicates that the running condition of the compressor is good, and the current does not exceed the limit value due to the influence of the high temperature of the outdoor unit environment, so that the frequency of the compressor does not need to be changed. If the comparison result shows that the current limit value is smaller than the current value of the current work of the compressor, the running condition of the compressor is overload running, the current exceeds the limit value due to the influence of high temperature in the environment of the outdoor unit, and further the running frequency of the compressor needs to be reduced until the current limit value is not smaller than the current value of the current work of the compressor.
Through the steps, the frequency of the compressor can be limited under the high-temperature condition, and the technical effect of ensuring the reliability of the outdoor unit is achieved.

Fig. 7 is a logic diagram of a control system according to an embodiment of the present invention, as shown in fig. 7, firstly, an outdoor ambient temperature needs to be detected to obtain an ambient temperature value of an outdoor unit, then, a current limit value is determined according to the ambient temperature value, the current limit value is compared with a compressor working current measured in real time, when the current limit value is smaller than the working current, the frequency of the compressor is reduced, and when the current limit value is not smaller than the working current, the frequency of the compressor is not subjected to intervention control.
