BEST MODE FOR CARRYING OUT THE INVENTION

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

It should be noted that the technical solutions of the various embodiments of the present invention can be combined with each other, but it must be based on the realization of those skilled in the art. When the combination of technical solutions is contradictory or cannot be realized, this technology should be considered The combination of schemes does not exist, nor is it within the scope of protection claimed by the present invention.

At first, technical line of the present invention is briefly summarized as follows:

When the air conditioner is running in the capacity test mode, it usually enters the fixed frequency mode, and the compressor runs at a fixed frequency, and the frequency cannot be adjusted and changed. Due to the consistency of air conditioners, or the impact of production, testing, and test operating environments, there may be situations where the test capability does not meet the requirements. But at this time, for the air conditioner, there may still be room for capacity improvement, and the test is deemed to be unqualified just because the frequency is fixed and the test capacity cannot meet the requirements. Rate. Without solving this technical problem, the present invention considers to conditionally adjust the operating parameters of the air conditioner during the test process to improve the accuracy of the test results and the pass rate of the test.

Please refer to FIG. 1 , which is a flow chart of the first embodiment of the air conditioner test operation control method of the present invention.

As shown in Figure 1, this embodiment adopts following process to carry out air conditioner test operation control:

Step 11: The air conditioner enters the capacity test mode to obtain real-time capacity values.

The real-time capability value is the capability value of the air conditioner detected in real time according to the set sampling frequency in the test mode. The characterization parameter and acquisition method of the real-time capability value can be realized by using the existing technology. As a preferred implementation, the real-time capability value is represented by the real-time air outlet temperature of the indoor unit.

Step 12: When the real-time capacity value does not meet the real-time target capacity value, perform the adjustment process: obtain the real-time system pressure value and real-time power module temperature value, compare them with the system pressure threshold and power module temperature threshold respectively, and adjust the compressor according to the comparison results Operating frequency and/or operating speed of the indoor fan.

The real-time target capability value is a known value, which is the target value that the air conditioner should reach in the current test mode. After the real-time capability value is acquired in step 11, it is compared with the real-time target capability value. If the real-time capability value does not meet the real-time target capability value, instead of directly outputting that the air conditioner test fails, an adjustment process is performed to determine whether the test capability value can reach the target capability value through adjustment.

The specific adjustment process is to adjust the frequency of the compressor and/or the speed of the indoor fan according to the system pressure value and the temperature value of the power module. Among them, the real-time system pressure value refers to the air conditioner system pressure value obtained in real time according to the set sampling frequency during the test process, which is generally the system high pressure value; the real-time power module temperature value refers to the air conditioner system pressure value obtained in real time according to the set sampling frequency during the test process. The temperature value of the power module of the power converter, the method for obtaining the two values is the prior art, and will not be described in more detail here. The system pressure threshold and the power module temperature threshold are known values, which are generally the corresponding values corresponding to the power upper limit in the current test mode. After the real-time system pressure value and the real-time power module temperature value are obtained, they are compared with the system pressure threshold and the power module temperature threshold respectively, and the operating frequency of the compressor and/or the operating speed of the indoor fan are adjusted according to the comparison results.

Using the method of this embodiment, when the air conditioner enters the capacity test mode, if the real-time capacity value does not meet the real-time target capacity value, compare the real-time system pressure value with the system pressure threshold value, and compare the real-time power module temperature value with the power module temperature threshold value For comparison, adjust the operating frequency of the compressor and/or the operating speed of the indoor fan according to the comparison results; therefore, during the test operation, the frequency of the compressor and/or the operating speed of the indoor fan are not fixed, but can be adjusted automatically, through this Automatic adjustment to overcome the discrepancy between the system capability and the actual product capability caused by the consistency of the air conditioner or the influence of the production, test or test environment, improve the accuracy of the test results, and increase the test pass rate; moreover, the frequency of the compressor And/or the operating speed of the indoor fan is not adjusted unlimitedly, but conditionally adjusted within an appropriate range based on the system pressure and power module temperature, to avoid mistesting and misjudgement of products that actually fail to meet the standards and to further ensure Accuracy of Test Results.

In some other preferred embodiments, the real-time target capability value is a dynamically variable value, and is determined by the following process:

Obtain the real-time target operating parameters when the air conditioner enters the capability test mode;

The real-time target capability value corresponding to the real-time target operating parameter is determined according to the real-time target operating parameter and the known corresponding relationship between the target operating parameter and the target capability value. Wherein, the corresponding relationship between the target operating parameter and the target capacity value is stored in the air conditioner in advance.

Fig. 2 shows the flow chart of the second embodiment of the air conditioner test operation control method of the present invention, specifically, according to the comparison result of the real-time system pressure value and the system pressure threshold value and the real-time power module temperature value and the power module temperature threshold value A flow chart of a specific example of adjusting the operating frequency of the compressor and/or the operating speed of the indoor fan based on the comparison result.

As shown in Figure 2, this embodiment adopts following process to carry out air conditioner test operation control:

Step 201: Obtain the difference between the system pressure threshold and the real-time system pressure value as the real-time pressure difference, and obtain the difference between the power module temperature threshold and the real-time power module temperature as the real-time temperature difference.

Step 202: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the first condition. If yes, go to step 203; otherwise, go to step 204.

Wherein, the first condition is: the real-time pressure difference is greater than the first pressure difference, and the real-time temperature difference is greater than the first temperature difference.

Both the first pressure difference and the first temperature difference are preset values, which may be specifically determined according to structural parameters, performance parameters, and test conditions of the air conditioner. For example, in a preferred embodiment, the first pressure difference is 0.4Mpa, and the first temperature difference is 6°C.

Step 203: Increase the operating frequency of the compressor, and control the compressor to run at the increased operating frequency.

In step 202, it is judged that when the first condition that the real-time pressure difference is greater than the first pressure difference and the real-time temperature difference is greater than the first temperature difference is satisfied, it indicates that there is a larger pressure difference and a larger temperature difference, with There is a large capacity improvement space. At this time, the operating frequency of the compressor will be increased, and the compressor will be controlled to run at the increased operating frequency to achieve the purpose of improving the capacity of the air conditioner.

Step 204: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the second condition. If yes, go to step 205; otherwise, go to step 206.

When it is determined in step 202 that the real-time pressure difference and the real-time temperature difference do not satisfy the first condition, it is further determined whether the second condition is satisfied. Wherein, the second condition is: the real-time pressure difference is not greater than the first pressure difference and greater than the second pressure difference, or the real-time temperature difference is not greater than the first temperature difference and greater than the second temperature difference. Both the second pressure difference and the second temperature difference are preset values, and are determined in the same way as the first pressure difference and the second temperature difference. Moreover, the first pressure difference is greater than the second pressure difference, and the first temperature difference is greater than the second temperature difference. For example, in a preferred embodiment, the second pressure difference is 0.2Mpa, and the second temperature difference is 3°C.

Step 205: Increase the operating speed of the indoor fan, and control the indoor fan to run at the increased operating speed.

When it is determined in step 204 that the real-time pressure difference and the real-time temperature difference meet the second condition, the operating frequency of the compressor is no longer adjusted to avoid misjudgment of the test results caused by forcedly increasing the operating frequency of the compressor. Instead, the operating speed of the indoor fan is adjusted. Adjustments to achieve small adjustments to system capabilities. Specifically, it is to increase the operating speed of the indoor fan and control the indoor fan to run at the increased operating speed to achieve the purpose of improving the capacity of the air conditioner.

Step 206: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the third condition. If yes, go to step 207; otherwise, go to step 201.

When it is determined in step 204 that the real-time pressure difference and the real-time temperature difference do not satisfy the second condition, it is further determined whether the third condition is satisfied. The third condition is: the real-time pressure difference is not greater than the second pressure difference, or the real-time temperature difference is not greater than the second temperature difference.

Step 207: The operating frequency of the compressor and the operating speed of the indoor fan remain unchanged.

When it is determined in step 204 that the real-time pressure difference and real-time temperature difference meet the third condition, the pressure difference or temperature difference is small, and there is little room for capacity improvement. No additional frequency or fan speed adjustment is performed, but the compressor is kept The operating frequency and the operating speed of the indoor fan remain unchanged to avoid inaccurate test results caused by forced adjustment.

Fig. 3 shows the flow chart of the third embodiment of the air conditioner test operation control method of the present invention, specifically, it is also based on the comparison result of the real-time system pressure value and the system pressure threshold value and the real-time power module temperature value and the power module temperature threshold value A flowchart of a specific example of adjusting the operating frequency of the compressor and/or the operating speed of the indoor fan based on the comparison results.

As shown in Figure 3, this embodiment adopts following process to carry out air conditioner test operation control:

Step 301: Obtain the difference between the system pressure threshold and the real-time system pressure value as the real-time pressure difference, and obtain the difference between the power module temperature threshold and the real-time power module temperature as the real-time temperature difference.

Step 302: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the first condition. If yes, go to step 303; otherwise, go to step 306.

Same as the embodiment in FIG. 2 , the first condition is: the real-time pressure difference is greater than the first pressure difference, and the real-time temperature difference is greater than the first temperature difference. The determination and values of the first pressure difference and the first temperature difference can refer to the embodiment in FIG. 2 .

Step 303: Increase the operating frequency of the compressor, and control the compressor to run at the increased operating frequency.

In step 302, it is judged that when the first condition that the real-time pressure difference is greater than the first pressure difference and the real-time temperature difference is greater than the first temperature difference is satisfied, it indicates that there is a larger pressure difference and a larger temperature difference, with There is a large capacity improvement space. At this time, the operating frequency of the compressor will be increased, and the compressor will be controlled to run at the increased operating frequency to achieve the purpose of improving the capacity of the air conditioner.

Step 304: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the fourth condition. If yes, go to step 305; otherwise, go to step 303.

During the operation of the compressor at the increased operating frequency, the real-time pressure difference and the real-time temperature difference are still obtained in real time, and it is judged whether the fourth condition is satisfied, and different controls are executed according to the judgment result. The fourth condition is: the real-time pressure difference is not greater than the third pressure difference or the real-time temperature difference is not greater than the third temperature difference. Both the third pressure difference and the third temperature difference are preset values, which are determined in the same way as the first pressure difference and the second temperature difference. Moreover, the third pressure difference is smaller than the second pressure difference described later, and the third temperature difference is also smaller than the second temperature difference described later.

Step 305: Stop increasing the operating frequency of the compressor.

If step 304 determines that the real-time pressure difference and real-time temperature difference meet the fourth condition, the pressure difference or temperature difference is small, and there is little room for capacity improvement, and the increase of the operating frequency of the compressor will be stopped.

In some other preferred embodiments, if the capacity value of the air conditioner still fails to meet the real-time target capacity value after the increase of the operating frequency of the compressor is stopped, the test result of the air conditioner test failing is output.

Step 306: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the second condition. If yes, go to step 309; otherwise, go to step 307.

When it is determined in step 202 that the real-time pressure difference and the real-time temperature difference do not meet the first condition, it is further determined whether the second condition is met, and corresponding control is performed according to the result of the determination. Wherein, the second condition is: the real-time pressure difference is not greater than the first pressure difference and greater than the second pressure difference, or the real-time temperature difference is not greater than the first temperature difference and greater than the second temperature difference. Moreover, the first pressure difference is greater than the second pressure difference, and the first temperature difference is greater than the second temperature difference; the determination and values of the second pressure difference and the second temperature difference can refer to the embodiment in FIG. 2 .

Step 307: Determine whether the real-time pressure difference and the real-time temperature difference satisfy the third condition. If yes, go to step 308; otherwise, go to step 301, and continue to execute the next cycle of judgment and processing.

When it is determined in step 306 that the real-time pressure difference and the real-time temperature difference do not meet the second condition, it is further determined whether the third condition is met, and corresponding control is performed according to the result of the determination. The third condition is: the real-time pressure difference is not greater than the second pressure difference, or the real-time temperature difference is not greater than the second temperature difference.

Step 308: The operating frequency of the compressor and the operating speed of the indoor fan remain unchanged. Then, go to step 313 .

If step 307 judges that the real-time pressure difference and real-time temperature difference meet the third condition, the pressure difference or temperature difference is small, and the capacity improvement space is small, no additional frequency or fan speed adjustment is performed, but the compressor is kept The operating frequency and the operating speed of the indoor fan remain unchanged to avoid inaccurate test results caused by forced adjustment. Then, go to step 313 .

Step 309: Increase the operating speed of the indoor fan, and control the indoor fan to run at the increased operating speed.

When it is determined in step 306 that the real-time pressure difference and the real-time temperature difference meet the second condition, the operating frequency of the compressor is no longer adjusted to avoid misjudgment of the test results caused by forcedly increasing the operating frequency of the compressor. Instead, the operating speed of the indoor fan is adjusted. Adjustments to achieve small adjustments to system capabilities. Specifically, it is to increase the operating speed of the indoor fan and control the indoor fan to run at the increased operating speed to achieve the purpose of improving the capacity of the air conditioner.

Step 310: Determine whether the increase value reaches the set wind speed increase threshold. If yes, execute step 311; otherwise, continue to execute the process of step 309.

During the operation of the indoor fan at the increased rotational speed, it is judged whether the increased value of the rotational speed reaches the set wind speed increase threshold. Wherein, the wind speed increase threshold is set as a preset known value.

Step 311: Stop increasing the running speed of the indoor fan.

If the increase in the operating speed of the indoor fan reaches the set wind speed increase threshold, the increase in the operating speed of the indoor fan will be stopped. Avoiding a forced increase in the wind speed is not beneficial to the capacity improvement, but also causes inaccurate test results. Then, step 312 is executed.

Step 312: Judging that the ability value satisfies the real-time target ability value. If yes, go to step 313; otherwise, go to step 314.

After stopping increasing the operating speed of the indoor fan, continue to judge whether the real-time capacity value meets the real-time target capacity value. If yes, go to step 313; if the real-time ability value does not meet the real-time target ability value,

Step 313: Continue testing.

If step 312 determines that the real-time capability value satisfies the real-time target capability value, continue to execute other testing processes.

Step 314: The air conditioner fails the test.

If it is determined in step 312 that the real-time capability value still does not meet the real-time target capability value, it will directly output that the test of the air conditioner fails. The test failure here refers to the failure of the ability test.

In some other preferred embodiments, in order to ensure the stability of the test and the accuracy of the test results, after the real-time capability value does not meet the real-time target capability value, first judge whether the system is running stably, and then execute the test after the system is stable. The process of adjusting the operating frequency of the compressor and/or the operating speed of the indoor fan.

As a preferred implementation, the following method is used to determine whether the system is running stably:

Judging whether the duration of the air conditioner running at a fixed operating current reaches the set time threshold;

If yes, it is judged that the system is running stably; otherwise, it is judged that the system is running unstable.
