technical field

Background technique

At present, air conditioners have been widely used as a common intelligent device for adjusting the temperature and humidity of indoor environment. Air conditioners have functions such as cooling and heating to adjust temperature. Among them, during the heating operation of the air conditioner, in order to reduce the possibility of the fluctuation of the air conditioner power caused by the fluctuation of the operating frequency of the compressor, thereby causing the fluctuation of the indoor temperature, it is necessary to control the temperature of the compressor according to the temperature of the inner coil of the air conditioner during the heating operation. Frequency raising and lowering includes: when the temperature of the inner coil reaches 48°C, performing the up-frequency operation of the air-conditioning compressor, and when the temperature of the inner coil reaches 56°C, performing the frequency-lowering operation of the air-conditioning compressor.

However, after the air conditioner has been running for a period of time, it will defrost, and during defrosting, the air conditioner operates in cooling mode, the temperature of the evaporator and the inner coil are both low, and the temperature in the room also drops to a certain extent. After the cooling operation is completed and the heating mode is restored, the temperature of the indoor coil rises slowly, so that the temperature of the inner coil detected by the air conditioner will be relatively small, and it will not reach the corresponding frequency of controlling the compressor's frequency according to the temperature of the inner coil. Therefore, the control of the frequency of the compressor generated according to the temperature protection of the inner coil cannot be implemented in time, which may cause the frequency to rise too fast, causing power fluctuations and then room temperature fluctuations, causing discomfort in the user's room.

Further improve the user experience.

FIG. 1 is a schematic flowchart of a method for controlling an air conditioner compressor provided by an embodiment of the present disclosure. As shown in Figure 1, the process for air conditioning compressor control includes:

Step 101: Obtain current compressor operating parameters when it is determined that the air conditioner completes the defrosting operation and enters the heating operation state.

After the air conditioner starts the heating operation, it will detect the temperature of the inner coil regularly or in real time, and then control the compressor's frequency up and down according to the detected temperature of the inner coil, including: when the temperature of the inner coil reaches 48°C, the air conditioner will be compressed. The frequency-up operation of the machine is performed, and when the temperature of the inner coil reaches 56°C, the down-frequency operation of the air conditioner compressor is performed. In the embodiment of the present disclosure, when the air conditioner is in heating operation, it is necessary not only to detect the temperature of the inner coil, but also to obtain the working parameters of the compressor, and to form and save the first correspondence between the working parameters of the compressor and the temperature of the inner coil . Therefore, in some embodiments, when it is determined that the air conditioner is in the heating operation state before the defrosting operation state, the temperature of the first inner coil detected by the air conditioner and the corresponding compressor operating parameters are obtained; tube temperature, control the operation of the compressor, and record the first inner coil temperature and the compressor operating parameter in the first correspondence.

The compressor operating parameters include one or more of: indoor ambient temperature, outdoor ambient temperature, and compressor operating frequency.

After the air conditioner has been in heating operation for a period of time, defrosting operation is required. During defrosting, the air conditioner operates in cooling mode, and the temperature of the evaporator and the inner coil is low. It is difficult for the coil temperature to reach the temperature corresponding to the frequency protection of the compressor in a short period of time. Therefore, in the embodiment of the present disclosure, when it is determined that the air conditioner has completed the defrosting operation and entered the heating operation state, the current compressor operating parameters are directly obtained, That is, one or more of the current indoor ambient temperature, the current outdoor ambient temperature, and the current compressor operating frequency are acquired.

Step 102: According to the stored first correspondence between the compressor operating parameters and the inner coil temperature, determine an estimated inner coil temperature matching the current compressor operating parameters.

When the air conditioner is in the heating operation state before the defrosting operation state, the first correspondence between the compressor operating parameters and the temperature of the inner coil has been configured and saved in the air conditioner, that is, the first correspondence is that the air conditioner is in the defrosting operation state. In this way, the estimated inner coil temperature that matches the current compressor operating parameters can be determined according to the first correspondence between the saved compressor operating parameters and the inner coil temperature.

Step 103: Control the operation of the compressor according to the estimated inner coil temperature.

In the related art, the operation of the compressor can 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, that is, in some embodiments, according to For the temperature of the first inner coil, controlling the operation of the compressor includes: when the temperature of the first inner coil is greater than or equal to the first set temperature, controlling the compressor to perform an up-frequency operation at a first rate; When the tube temperature is greater than or equal to the second set temperature, the compressor is controlled to perform a down-frequency operation at a second rate; wherein the first set temperature is lower than the second set temperature.

For example: if the temperature of the first inner coil is greater than or equal to 48°C, the compressor is controlled to increase the frequency at a rate of 1HZ/10S, and if the temperature of the first inner coil is greater than or equal to 52°C, the compressor is controlled to decrease at a rate of 1HZ/10S. Frequency operation, where the first set temperature of 48°C is lower than the second set temperature of 52°C.

Of course, according to the temperature of the first inner coil, the operation of the control compressor can be further subdivided, the temperature can be set, and different compressor controls can be performed when different temperatures are reached, including: slow-speed up-frequency operation, fast up-frequency operation, Frequency unchanged operation, slow down-frequency operation, fast down-frequency operation, and stop operation, etc.

In the embodiment of the present disclosure, the air conditioner completes the defrosting operation and enters the heating operation state, and determines the estimated inner coil temperature matching the current compressor operating parameters. At this time, according to the estimated inner coil temperature, control operation of the compressor. In the control process, the estimated inner coil temperature is compared with the preset temperature, and then the corresponding control is performed according to the comparison result. Different temperature division and control are carried out.

In some embodiments, controlling the operation of the compressor according to the estimated inner coil temperature includes: when the estimated inner coil temperature is greater than or equal to a third set temperature, controlling the compressor to up-frequency at a third rate operation, 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; when the estimated inner coil temperature is greater than or equal to the second set temperature, the compressor is controlled to operate at the first speed. Four-rate down-conversion operation, where the fourth rate is less than or equal to the second rate.

The third set temperature may be 48°C, or may be 45°C, 42°C or 40°C. For example, the estimated inner coil temperature is ≥40°C, and the compressor is controlled to run at a rate of 1HZ/10S, 1HZ/20S, or 1HZ/50S, etc. That is, the third rate may be less than or equal to the first rate. Among them, the compressor's frequency-up rate has been degraded, which can increase the heating time of the coil, reduce the fluctuation of the air conditioner power, and further reduce the fluctuation of the room temperature. Of course, if the estimated inner coil temperature is ≥56°C, the compressor can also be controlled to run at 1HZ/10S, 1HZ/50S, or 1HZ/100S to reduce the frequency.

Similarly, according to the estimated inner coil temperature, control the operation of the compressor, including: slow up-frequency operation, fast up-frequency operation, constant frequency operation, slow-speed down-frequency operation, fast down-frequency operation, and stop operation, etc. . Therefore, in some embodiments, controlling the operation of the compressor further includes: in the case that the estimated inner coil temperature is greater than or equal to a fourth set temperature, controlling the compressor to stop the frequency-up operation, wherein the fourth set temperature It is greater than the first set temperature and less than the second set temperature; when the estimated inner coil temperature is greater than or equal to the fifth set temperature, the compressor is controlled to stop running, wherein the fifth set temperature is greater than the second set temperature. fixed temperature.

For example: when the estimated inner coil temperature is greater than or equal to 40°C, the compressor is controlled to increase the frequency slowly, and the frequency increase speed is the third rate of 1HZ/10S; when the estimated inner coil temperature is greater than or equal to 52°C, the compressor is controlled to stop increasing the frequency. Frequency operation; when the estimated inner coil temperature is ≥56°C, control the compressor to run at a slow frequency reduction, and the speed is the fourth speed of 1HZ/10S; when the estimated inner coil temperature is ≥59°C, control the compressor to quickly reduce the frequency Run at a speed of 1HZ/1S; when the estimated inner coil temperature is greater than or equal to 63°C, control the compressor to stop running to protect the compressor. After shutdown, when the estimated inner coil temperature is less than or equal to 38℃, control the compressor to start running.

It can be seen that in this embodiment, when the air conditioner performs heating operation after defrosting, the compression control is not based on the detected inner coil temperature, but according to the inner coil temperature before defrosting that matches the working parameters of the compressor. In this way, the control of the compressor frequency according to the temperature protection of the inner coil can not be implemented in time, and the probability of power fluctuations and room temperature fluctuations caused by the frequency rising too fast is reduced, and the effect of heating operation is improved. It also further improves the user experience.

After the air conditioner completes the defrosting operation and enters the heating operation state, the operation of the compressor can be controlled according to the temperature of the inner coil before defrosting that matches the working parameters of the compressor. In some embodiments, the estimated inner coil temperature may also be compared with the second inner coil temperature detected by the air conditioner, and when the estimated inner coil temperature matches the second inner coil temperature detected by the air conditioner, according to The temperature of the second inner coil controls the operation of the compressor. The difference between the estimated inner coil temperature and the temperature of the second inner coil detected by the air conditioner is within the set range, that is, the estimated inner coil temperature matches the temperature of the second inner coil detected by the air conditioner. It can be seen that the air conditioner The actual temperature of the coil has increased, not the temperature after defrosting. At this time, the operation of the compressor can be controlled according to the temperature of the second inner coil. At this time, the operation can be continued according to the control process in the related art. Of course, the corresponding relationship between the working parameters of the compressor and the temperature of the inner coil can continue to be recorded and saved. Therefore, after the air conditioner is defrosted again, it will continue to be based on the estimated The inner coil temperature controls the operation of the compressor.

The operation procedures are grouped into specific embodiments below to illustrate the control process for an air conditioner compressor provided by the embodiments of the present invention.

In this embodiment, the air conditioners are respectively configured with a first set temperature of 48°C, a second set temperature may include: 57°C, a third set temperature of 42°C, a fourth set temperature of 52°C, and a fifth set temperature of 52°C. The set temperature is 60°C, and the sixth set temperature is 40°C. Of course, the first rate, the second rate, the third rate, and the fourth rate are also set respectively.

FIG. 2 is a schematic flowchart of a method for controlling an air conditioner compressor provided by an embodiment of the present disclosure. Referring to Figure 2, the process for air conditioning compressor control includes:

Step 201 : the air conditioner is in heating operation, and the temperature of the first inner coil detected by the air conditioner and the corresponding compressor operating parameters are collected.

In this embodiment, the air conditioner may collect data periodically or in real time to obtain the temperature of the first inner coil detected by the air conditioner and the corresponding compressor operating parameters. Compressor operating parameters may include indoor ambient temperature, outdoor ambient temperature, and compressor operating frequency.

Step 202 : Configure and save the first correspondence between the temperature of the first inner coil and the operating parameters of the compressor.

Step 203: Control the operation of the compressor according to the temperature of the first inner coil.

When the temperature of the first inner coil reaches different set temperatures, different compressor operations are performed, including: slow-speed up-frequency operation, fast-speed up-frequency operation, constant frequency operation, slow-speed down-frequency operation, fast down-frequency operation, Stop running and start running, etc.

Step 204: Determine whether to enter the defrosting operation? If yes, go to step 205; otherwise, go back to step 201.

Step 205: Determine whether the defrosting operation is completed and the heating operation is entered? If yes, go to step 206; otherwise, go back to step 204.

Step 206: Acquire current compressor operating parameters.

Likewise, here, the current compressor operating parameters include: the current indoor ambient temperature, the current outdoor ambient temperature, and the current compressor operating frequency.

Step 207 : According to the stored first correspondence between the compressor operating parameters and the inner coil temperature, determine the estimated inner coil temperature matching the current compressor operating parameters.

Step 208: Control the operation of the compressor according to the estimated inner coil temperature.

It is estimated that the temperature of the inner coil reaches different set temperatures, and different compressor operations are performed, including: slow-speed up-frequency operation, fast-frequency up-frequency operation, constant frequency operation, slow-speed down-frequency operation, and fast-frequency down-frequency operation, Stop running and start running, etc. For example: when the estimated inner coil temperature is greater than or equal to 42°C, control the compressor to slowly increase the frequency, and the frequency increase speed is the third rate of 1HZ/10S; when the estimated inner coil temperature is greater than or equal to 52°C, control the compressor to stop the frequency increase operation. ; When the estimated inner coil temperature is ≥57°C, control the compressor to run at a low frequency, and the speed is the fourth speed of 1HZ/10S; when the estimated inner coil temperature is ≥60°C, control the compressor to stop running to protect the compression machine. After shutdown, when the estimated inner coil temperature is less than or equal to 40℃, control the compressor to start running.

Step 209: Determine whether the estimated 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 temperature of the second inner coil is detected by the air conditioner after defrosting the air conditioner.

It can be seen that in this embodiment, when the air conditioner performs heating operation after defrosting, the compression control is not based on the detected inner coil temperature, but according to the inner coil temperature before defrosting that matches the working parameters of the compressor. In this way, the control of the compressor frequency according to the temperature protection of the inner coil can not be implemented in time, and the probability of power fluctuations and room temperature fluctuations caused by the frequency rising too fast is reduced, and the effect of heating operation is improved. It also further improves the user experience.

According to the above-described process for air conditioner compressor control, an apparatus for air conditioner compressor control can be constructed.

For example: the slow rate can be 1HZ/10S, and the fast rate can be 1HZ/1S.

FIG. 4 is a schematic structural diagram of a control device for an air conditioner compressor provided by an embodiment of the present disclosure. As shown in FIG. 4 , the control device for an air conditioner compressor includes: a first acquisition module 310, a first determination module 320, a first control module 330, a second acquisition module 340, a record keeping module 350, a second control module 360, and switching module 370 .

The second acquisition module 340 may collect the temperature of the first inner coil detected by the air conditioner and the corresponding compressor operating parameters after the air conditioner is turned on for heating operation. In this way, the record keeping module 350 may be configured to save the first correspondence between the temperature of the first inner coil and the operating parameters of the compressor. The second control module 360 can control the operation of the compressor according to the temperature of the first inner coil.

When the air conditioner completes the defrosting operation and enters the heating operation state, the first obtaining module 310 can obtain the current compressor operating parameters. Therefore, the first determining module 320 can determine the estimated inner coil temperature matching the current compressor working parameters according to the first correspondence between the compressor working parameters and the inner coil temperature saved by the record keeping module 350 . In this way, the first control module 330 can control the operation of the compressor according to the estimated inner coil temperature. Similarly, it is estimated that the temperature of the inner coil reaches different set temperatures, and different compressor operations are performed, including: slow-speed up-frequency operation, fast-frequency up-frequency operation, constant frequency operation, slow-speed down-frequency operation, and fast-frequency down-frequency operation run, stop running, and start running, etc. For example: when the estimated inner coil temperature is greater than or equal to 42°C, the first control module 330 controls the compressor to run with a slow frequency increase, and the frequency increase speed is the third rate of 1HZ/10S; when the estimated inner coil temperature is greater than or equal to 52°C, the first control module 330 The control module 330 controls the compressor to stop frequency-up operation; when the estimated inner coil temperature is greater than or equal to 56°C, the first control module 330 controls the compressor to slowly reduce the frequency to operate at a speed of 1HZ/10S; when the estimated inner coil temperature is greater than or equal to 56°C When the temperature is 59°C, the first control module 330 controls the compressor to run at a low frequency at a speed of 1HZ/S; when the estimated inner coil temperature is greater than or equal to 60°C, the first control module 330 controls the compressor to stop running to protect the compressor. After shutdown, when the estimated inner coil temperature is less than or equal to 40°C, the first control module 330 controls the compressor to start running.
