In the embodiment of the disclosure, the air conditioner is operated in a heating mode, and before defrosting is not performed, the first corresponding relation between the working parameters of the compressor and the temperature of the inner coil is stored, so that under the condition that defrosting operation is completed and the air conditioner enters a heating operation state, the estimated temperature of the inner coil matched with the current working parameters of the compressor can be determined according to the first corresponding relation, and the operation of the compressor is controlled according to the estimated temperature of the inner coil.
Fig. 1 is a schematic flowchart of a control method for an air conditioner compressor according to an embodiment of the present disclosure. As shown in fig. 1, the process for air conditioner compressor control includes:
step 101: and under the condition that the air conditioner is determined to finish defrosting operation and enter a heating operation state, acquiring the working parameters of the current compressor.
After the air conditioner starts the operation of heating, can regularly or in real time, detect interior coil pipe temperature, then, according to the interior coil pipe temperature control compressor that detects the raising and lowering of frequency, include: the up-conversion operation of the air conditioner compressor is performed when the temperature of the inner coil reaches 48 c, and the down-conversion operation of the air conditioner compressor is performed when the temperature of the inner coil reaches 56 c. In the embodiment of the disclosure, when the air conditioner is operated in heating, not only the temperature of the inner coil needs to be detected, but also the working parameters of the compressor need to be acquired, and a first corresponding relationship between the working parameters of the compressor and the temperature of the inner coil is formed and stored. Therefore, in some embodiments, in the case that it is determined that the air conditioner is in the heating operation state before the defrosting operation state, the first inner coil temperature detected by the air conditioner and the corresponding compressor operation parameter are acquired; and controlling the operation of the compressor according to the temperature of the first internal coil, and recording the temperature of the first internal coil and the working parameters of the compressor in the first corresponding relation.
Wherein, compressor operating parameters include: one or more of an indoor ambient temperature, an outdoor ambient temperature, and a compressor operating frequency.
After the air conditioner is heated and operated for a period of time, the defrosting operation is needed, and when the air conditioner is in a refrigerating mode, the temperatures of the evaporator and the inner coil pipe are lower, so that after the defrosting operation is completed and the air conditioner enters a heating operation state, the temperature of the inner coil pipe is difficult to reach the temperature corresponding to the frequency protection of the compressor in a short time.
Step 102: and determining the estimated temperature of the inner coil matched with the current working parameters of the compressor according to the stored first corresponding relation between the working parameters of the compressor and the temperature of the inner coil.
When the air conditioner is in a heating running state before a defrosting running state, a first corresponding relation between the working parameters of the compressor and the temperature of the inner coil is configured and stored in the air conditioner, namely the first corresponding relation is recorded before the air conditioner enters the defrosting running state, so that the estimated temperature of the inner coil matched with the current working parameters of the compressor can be determined according to the stored first corresponding relation between the working parameters of the compressor and the temperature of the inner coil.
Step 103: and controlling the operation of the compressor according to the estimated temperature of the inner coil.
In the related art, the operation of the compressor may be controlled according to the temperature of the first inner coil detected by the air conditioner, including: frequency up control, frequency down control, shutdown control, etc. of the compressor, i.e., in some embodiments, controlling the operation of the compressor based on the first inner coil temperature comprises: controlling the compressor to perform frequency-increasing operation at a first speed under the condition that the temperature of the first inner coil is greater than or equal to a first set temperature; controlling the compressor to perform frequency reduction operation at a second speed under the condition that the temperature of the first inner coil is greater than or equal to a second set temperature; wherein the first set temperature is less than the second set temperature.
For example: and if the temperature of the first inner coil is more than or equal to 48 ℃, controlling the compressor to perform frequency increasing operation at the rate of 1HZ/10S, and if the temperature of the first inner coil is more than or equal to 52 ℃, controlling the compressor to perform frequency decreasing operation at the rate of 1HZ/10S, wherein the first set temperature of 48 ℃ is less than the second set temperature of 52 ℃.
Of course, according to first interior coil pipe temperature, can further subdivide in the operation of control compressor, carry out the temperature and set for, reach different temperatures and carry out different compressor controls, include: slow up-frequency operation, fast up-frequency operation, constant frequency operation, slow down-frequency operation, fast down-frequency operation, and stop operation, etc.
In the embodiment of the disclosure, the air conditioner completes defrosting operation and enters a heating operation state, and determines the estimated inner coil temperature matched with the current working parameter of the compressor, and at this time, the operation of the compressor can be controlled according to the estimated inner coil temperature. In the control process, the estimated temperature of the inner coil is compared with the preset temperature, and then the corresponding control is carried out according to the comparison result, and the process of the corresponding control according to the comparison result can be the same as the control process in the related technology, and certainly, different temperature division and control can also be carried out.
In some embodiments, controlling operation of the compressor based on the estimated inner coil temperature comprises: under the condition that the predicted temperature of the inner coil is greater than or equal to a third set temperature, controlling the compressor to perform frequency-increasing operation at a third speed, wherein the third set temperature is less than the first set temperature, and the third speed is less than or equal to the first speed; and under the condition that the estimated temperature of the inner coil is greater than or equal to a second set temperature, controlling the compressor to perform frequency reduction operation at a fourth speed, wherein the fourth speed is less than or equal to the second speed.
The third set temperature may be 48 ℃, or may be 45 ℃, 42 ℃ or 40 ℃. For example: the temperature of the inner coil is estimated to be more than or equal to 40 ℃, and the compressor is controlled to carry out frequency-increasing operation at the speed of 1HZ/10S, 1HZ/20S, 1HZ/50S and the like. I.e. the third rate may be less than or equal to the first rate. The compressor frequency raising rate is lowered, time can be prolonged for raising the temperature of the coil pipe, fluctuation of air conditioner power is reduced, and fluctuation of room temperature is further reduced. Of course, the temperature of the inner coil is estimated to be more than or equal to 56 ℃, and the compressor can also be controlled to perform the frequency reduction operation at 1HZ/10S, 1HZ/50S or 1 HZ/100S.
Also, controlling operation of the compressor based on the estimated inner coil temperature includes: slow up-frequency operation, fast up-frequency operation, constant frequency operation, slow down-frequency operation, fast down-frequency operation, and stop operation, etc. Accordingly, in some embodiments, controlling operation of the compressor further comprises: under the condition that the estimated temperature of the inner coil is greater than or equal to a fourth set temperature, controlling the compressor to stop increasing the frequency, wherein the fourth set temperature is greater than the first set temperature and less than the second set temperature; and under the condition that the estimated temperature of the inner coil is greater than or equal to a fifth set temperature, controlling the compressor to stop running, wherein the fifth set temperature is greater than the second set temperature.
For example: when the predicted temperature of the inner coil is more than or equal to 40 ℃, controlling the compressor to slowly increase the frequency, wherein the frequency increasing speed is a third rate of 1 HZ/10S; when the temperature of the inner coil is estimated to be more than or equal to 52 ℃, controlling the compressor to stop increasing the frequency; when the predicted temperature of the inner coil is more than or equal to 56 ℃, controlling the compressor to operate at a slow down frequency at the fourth speed of 1 HZ/10S; when the predicted temperature of the inner coil is more than or equal to 59 ℃, controlling the compressor to operate at a fast frequency reduction speed of 1 HZ/1S; and when the temperature of the inner coil is estimated to be more than or equal to 63 ℃, controlling the compressor to stop running and protecting the compressor. And after the machine is stopped, when the temperature of the inner coil is estimated to be less than or equal to 38 ℃, controlling the compressor to start to operate.
Therefore, in the embodiment, when the air conditioner performs heating operation after defrosting, the operation of the compressor is controlled not according to the detected temperature of the inner coil, but according to the temperature of the inner coil before defrosting, which is matched with the working parameters of the compressor, so that the problem that the control of the frequency of the compressor cannot be implemented in time according to the protection of the temperature of the inner coil is avoided, the probability of fluctuation of the room temperature caused by power fluctuation due to too fast frequency rise is reduced, the heating operation effect is improved, and the user experience is further improved.
After the air conditioner finishes defrosting operation and enters a heating operation state, the operation of the compressor can be controlled according to the temperature of the inner coil pipe before defrosting, which is matched with the working parameters of the compressor. In some embodiments, the estimated temperature of the inner coil may be compared with a second temperature of the inner coil detected by the air conditioner, and when the estimated temperature of the inner coil matches the second temperature of the inner coil detected by the air conditioner, the operation of the compressor may be controlled according to the second temperature of the inner coil. The difference between the estimated temperature of the inner coil and the temperature of the second inner coil detected by the air conditioner is within the set range, namely the estimated temperature of the inner coil is matched with the temperature of the second inner coil detected by the air conditioner, so that the actual temperature of the air conditioner coil is increased and is not the temperature after defrosting, and at the moment, the operation of the compressor can be continuously controlled according to the temperature of the second inner coil. At this moment, the operation can be continuously carried out according to the control process in the related technology, and of course, the corresponding relation between the working parameters of the compressor and the temperature of the inner coil can be continuously recorded and stored, so that the operation of the compressor can be continuously controlled according to the estimated temperature of the inner coil after the air conditioner is defrosted again.
The following operational procedures are integrated into a specific embodiment to illustrate the control process for the air conditioner compressor provided by the embodiment of the present invention.
In this embodiment, the air conditioner is configured with a first set temperature of 48 ℃, and the second set temperature may include: the third set temperature was 42 ℃, the fourth set temperature was 52 ℃, the fifth set temperature was 60 ℃, and the sixth set temperature was 40 ℃, although the first rate, the second rate, the third rate, and the fourth rate were also set, respectively.

For example: when the temperature of the inner coil is estimated to be more than or equal to 42 ℃, controlling the compressor to slowly increase the frequency, wherein the frequency increasing speed is a third rate of 1 HZ/10S; when the temperature of the inner coil is estimated to be more than or equal to 52 ℃, controlling the compressor to stop raising the frequency; when the predicted temperature of the inner coil is more than or equal to 57 ℃, controlling the compressor to operate at a slow down frequency at a fourth speed of 1 HZ/10S; and when the temperature of the inner coil is estimated to be more than or equal to 60 ℃, controlling the compressor to stop running and protecting the compressor. And after the machine is stopped, when the temperature of the inner coil is estimated to be less than or equal to 40 ℃, controlling the compressor to start to operate.
Step 209: is it determined whether the predicted inner coil temperature matches the second inner coil temperature detected by the air conditioner? If yes, go back to step 201, otherwise, go back to step 206.
The second inner coil temperature is detected by the air conditioner after the air conditioner has undergone defrosting.
Therefore, in the embodiment, when the air conditioner performs heating operation after defrosting, the operation of the compressor is controlled not according to the detected temperature of the inner coil, but according to the temperature of the inner coil before defrosting, which is matched with the working parameters of the compressor, so that the problem that the control of the frequency of the compressor cannot be implemented in time according to the protection of the temperature of the inner coil is avoided, the probability of fluctuation of the room temperature caused by power fluctuation due to too fast frequency rise is reduced, the heating operation effect is improved, and the user experience is further improved.
