Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
It should be noted that the technical solutions in the embodiments of the present invention may be combined with each other, but must be based on the realization of the technical solutions by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not to be within the protection scope of the present invention.
First, the technical route of the present invention is briefly summarized as follows:
when the air conditioner operates in the capacity test mode, the air conditioner generally enters a fixed frequency mode, and the compressor operates at a fixed frequency, so that the adjustment and the change of the frequency cannot be performed. The situation that the testing capability does not meet the requirement can occur because of the consistency problem of the air conditioner or the influence of production, test operation environment and the like. However, for the air conditioner, the air conditioner may still have a capacity improvement space, and the air conditioner is determined to be unqualified when the testing capacity cannot meet the requirement only because the frequency of the air conditioner is fixed, so that the air conditioner is not only inaccurate in testing and generates misjudgment, but also reduces the testing passing rate. The invention considers conditionally adjusting the air conditioner operation parameters in the test process to improve the accuracy of the test result and the test passing rate.
Referring to fig. 1, a flowchart of a control method for testing operation of an air conditioner according to a first embodiment of the present invention is shown.
As shown in fig. 1, this embodiment performs air conditioner test operation control using the following procedure:
step 11: and the air conditioner enters a capacity test mode to obtain a real-time capacity value.
The real-time capacity value is the capacity value of the air conditioner detected in real time according to the set sampling frequency in the test mode. The representation parameters of the real-time capability value and the acquisition method can be realized by adopting the prior art. As a preferred embodiment, the real-time capacity value is represented by the real-time air outlet temperature of the indoor unit.
Step 12: when the real-time capability value does not meet the real-time target capability value, executing an adjusting process: and acquiring a real-time system pressure value and a real-time power module temperature value, comparing the real-time system pressure value and the real-time power module temperature value with a system pressure threshold value and a power module temperature threshold value respectively, and adjusting the running frequency of the compressor and/or the running rotating speed of the indoor fan according to a comparison result.
The real-time target capacity value is a known value and is a target value which 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 capacity value does not meet the real-time target capacity value, the air conditioner is not directly output to be unqualified in test, but an adjusting process is executed, and whether the tested capacity value can reach the target capacity value or not is determined through adjustment.
And in the specific adjusting process, the frequency of the compressor and/or the rotating speed of the indoor fan are adjusted according to the system pressure value and the power module temperature value. The real-time system pressure value refers to an air conditioner system pressure value obtained in real time according to a set sampling frequency in the testing process, and is generally a system high-pressure value; the real-time power module temperature value refers to a temperature value of the air conditioner power module obtained in real time according to a set sampling frequency in a testing process, and a method for obtaining the two values is the prior art and is not described in more detail herein. The system pressure threshold and the power module temperature threshold are known values, and are generally corresponding values corresponding to the upper power limit in the current test mode. And after the real-time system pressure value and the real-time power module temperature value are obtained, comparing the real-time system pressure value and the real-time power module temperature value with a system pressure threshold value and a power module temperature threshold value respectively, and adjusting the running frequency of the compressor and/or the running rotating speed of the indoor fan according to the comparison result.
By adopting the method of the 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, the real-time system pressure value is compared with the system pressure threshold value, the real-time power module temperature value is compared with the power module temperature threshold value, and the running frequency of the compressor and/or the running rotating speed of the indoor fan are/is adjusted according to the comparison result; therefore, in the test operation process, the frequency of the compressor and/or the operation rotating speed of the indoor fan are not fixed but can be automatically adjusted, and by means of the automatic adjustment, the problem that the system capacity does not accord with the actual capacity of a product due to the consistency problem of the air conditioner or the influence of production, test or test environment and the like is solved, the accuracy of a test result is improved, and the test passing rate is increased; moreover, the frequency of the compressor and/or the running speed of the indoor fan are/is not adjusted without limit, but are conditionally adjusted within a proper range based on the system pressure and the temperature of the power module, so that misdetection and misjudgment that products which cannot reach the standard are forced to pass the test are avoided, and the accuracy of the test result is further ensured.
In other preferred embodiments, the real-time target capability value is a dynamically variable value and is determined using the following process:
acquiring real-time target operation parameters when the air conditioner enters a capacity test mode;
and determining a real-time target capability value corresponding to the real-time target operation parameter according to the real-time target operation parameter and the corresponding relation between the known target operation parameter and the target capability value. And the corresponding relation between the target operation parameters and the target capacity value is stored in the air conditioner in advance.
Fig. 2 is a flowchart illustrating a second embodiment of the air conditioner test operation control method according to the present invention, and more particularly, to a flowchart illustrating a specific example of adjusting the operation frequency of the compressor and/or the operation speed of the indoor fan according to the comparison result between the real-time system pressure value and the system pressure threshold value and the comparison result between the real-time power module temperature value and the power module temperature threshold value.
As shown in fig. 2, this embodiment performs air conditioner test operation control using the following procedure:
step 201: and acquiring a difference value between a system pressure threshold value and a real-time system pressure value as a real-time pressure difference value, and acquiring a difference value between a power module temperature threshold value and a real-time power module temperature value as a real-time temperature difference value.
Step 202: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a first condition. If yes, go to step 203; otherwise, step 204 is performed.
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.
The first pressure difference value and the first temperature difference value are preset values and can be determined according to air conditioner structural parameters, performance parameters, test conditions and the like. For example, in a preferred embodiment, the first pressure difference is 0.4MPa and the first temperature difference is 6 ℃.
Step 203: and increasing the running frequency of the compressor, and controlling the compressor to run at the increased running frequency.
If it is determined in step 202 that 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 a larger pressure difference and a larger temperature difference exist, and a larger capacity-increasing space exists, and at this time, the operating frequency of the compressor is increased, and the compressor is controlled to operate at the increased operating frequency, so as to achieve the purpose of increasing the capacity of the air conditioner.
Step 204: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a second condition. If yes, go to step 205; otherwise, step 206 is performed.
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 a second condition is satisfied. Wherein the second condition is: the real-time pressure difference is not greater than the first pressure difference and is greater than the second pressure difference, or the real-time temperature difference is not greater than the first temperature difference and is greater than the second temperature difference. The second pressure difference value and the second temperature difference value are preset values, and the determining mode is the same as the first pressure difference value and the second temperature difference value. Moreover, the first pressure differential is greater than the second pressure differential, and the first temperature differential is greater than the second temperature differential. For example, in a preferred embodiment, the second pressure difference is 0.2MPa and the second temperature difference is 3 ℃.
Step 205: and increasing the running rotating speed of the indoor fan, and controlling the indoor fan to run at the increased running rotating speed.
When the real-time pressure difference value and the real-time temperature difference value meet the second condition in the step 204, the operation frequency of the compressor is not adjusted any more, misjudgment of a test result caused by forcibly increasing the operation frequency of the compressor is avoided, the operation rotating speed of the indoor fan is adjusted, and small-amplitude adjustment of the system capacity is realized. Specifically, the running speed of the indoor fan is increased, and the indoor fan is controlled to run at the increased running speed, so that the purpose of improving the capacity of the air conditioner is achieved.
Step 206: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a 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 a 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 running frequency of the compressor and the running speed of the indoor fan are kept unchanged.
When it is determined in step 204 that the real-time pressure difference value and the real-time temperature difference value satisfy the third condition, the pressure difference value or the temperature difference value is small, the capacity improvement space is small, extra frequency or fan speed adjustment is not performed, the compressor operation frequency and the indoor fan operation speed are kept unchanged, and inaccurate test results caused by forced adjustment are avoided.
Fig. 3 is a flowchart illustrating a third embodiment of the method for controlling the test operation of the air conditioner according to the present invention, and in particular, is a flowchart illustrating a specific example of adjusting the operation frequency of the compressor and/or the operation speed of the indoor fan according to the comparison result between the real-time system pressure value and the system pressure threshold and the comparison result between the real-time power module temperature value and the power module temperature threshold.
As shown in fig. 3, this embodiment performs air conditioner test operation control using the following procedure:
step 301: and acquiring a difference value between a system pressure threshold value and a real-time system pressure value as a real-time pressure difference value, and acquiring a difference value between a power module temperature threshold value and a real-time power module temperature value as a real-time temperature difference value.
Step 302: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a first condition. If yes, go to step 303; otherwise, step 306 is performed.
As in the embodiment of 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 value of the first pressure difference and the first temperature difference can refer to the embodiment of fig. 2.
Step 303: and increasing the running frequency of the compressor, and controlling the compressor to run at the increased running frequency.
In step 302, it is determined 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 a larger pressure difference and a larger temperature difference exist, and the capacity of the air conditioner is increased, at this time, the operating frequency of the compressor is increased, and the compressor is controlled to operate at the increased operating frequency, so as to achieve the purpose of increasing the capacity of the air conditioner.
Step 304: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a fourth condition. If yes, go to step 305; otherwise, go to step 303.
And in the process that the compressor runs at the increased running frequency, the real-time pressure difference value and the real-time temperature difference value are still obtained in real time, whether the fourth condition is met or not is judged, and different controls are executed according to the judgment result. The fourth condition is that: 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. The third pressure difference value and the third temperature difference value are both preset values, and the determination mode is the same as the first pressure difference value and the second temperature difference value. The third pressure difference is smaller than a second pressure difference described later, and the third temperature difference is also smaller than a second temperature difference described later.
Step 305: the increase in the operating frequency of the compressor is stopped.
If step 304 determines that the real-time pressure difference and the real-time temperature difference satisfy the fourth condition, the pressure difference or the temperature difference is small, the capacity-increasing space is small, and the increase of the operating frequency of the compressor is stopped.
In other preferred embodiments, if the air conditioner capacity value still cannot meet the real-time target capacity value after the increase of the running frequency of the compressor is stopped, a test result that the air conditioner test is not qualified is output.
Step 306: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a second condition. If yes, go to step 309; otherwise, step 307 is executed.
When it is determined in step 202 that the real-time pressure difference value and the real-time temperature difference value do not satisfy the first condition, it is further determined whether a second condition is satisfied, and corresponding control is executed according to the determination result. Wherein the second condition is: the real-time pressure difference is not greater than the first pressure difference and is greater than the second pressure difference, or the real-time temperature difference is not greater than the first temperature difference and is 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 value of the second pressure difference and the second temperature difference can refer to the embodiment of fig. 2.
Step 307: and judging whether the real-time pressure difference value and the real-time temperature difference value meet a third condition. If yes, go to step 308; otherwise, go to step 301, continue to execute the next cycle of judgment and processing.
When it is determined in step 306 that the real-time pressure difference value and the real-time temperature difference value do not satisfy the second condition, it is further determined whether a third condition is satisfied, and corresponding control is executed according to the determination result. 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 running frequency of the compressor and the running speed of the indoor fan are kept unchanged. Then, go to step 313.
If it is determined in step 307 that the real-time pressure difference and the real-time temperature difference satisfy the third condition, the pressure difference or the temperature difference is small, the capacity improvement space is small, additional frequency or fan speed adjustment is not performed, but the compressor operation frequency and the indoor fan operation speed are kept unchanged, and inaccurate test results caused by forced adjustment are avoided. Then, go to step 313.
Step 309: and increasing the running rotating speed of the indoor fan, and controlling the indoor fan to run at the increased running rotating speed.
When the real-time pressure difference value and the real-time temperature difference value meet the second condition, the operation frequency of the compressor is not adjusted any more, misjudgment of a test result caused by forcibly increasing the operation frequency of the compressor is avoided, the operation rotating speed of the indoor fan is adjusted, and small-amplitude adjustment of the system capacity is achieved. Specifically, the running speed of the indoor fan is increased, and the indoor fan is controlled to run at the increased running speed, so that the purpose of improving the capacity of the air conditioner is achieved.
Step 310: and judging whether the increment value reaches a set wind speed increment threshold value or not. If yes, go to step 311; otherwise, the process continues with step 309.
And judging whether the increase value of the rotating speed reaches a set wind speed increase threshold value or not in the process that the indoor fan runs at the increased rotating speed. Wherein the wind speed increase threshold value is set to a preset known value.
Step 311: and stopping increasing the running rotating speed of the indoor fan.
If the increase value of the operating rotating speed of the indoor fan reaches the set wind speed increase threshold value, the increase of the operating rotating speed of the indoor fan is stopped, and the situation that the forced increase of the wind speed is not only beneficial to the capacity improvement but also causes inaccurate test results is avoided. Then, step 312 is performed.
Step 312: and judging that the capacity value meets the real-time target capacity value. If yes, go to step 313; otherwise, step 314 is performed.
And after the increase of the running rotating speed of the indoor fan is stopped, continuously judging whether the real-time capacity value meets the real-time target capacity value. If yes, go to step 313; if the real-time capability value does not satisfy the real-time target capability value,
step 313: the test is continued.
If step 312 determines that the real-time capability value satisfies the real-time target capability value, other testing processes continue to be performed.
Step 314: and the air conditioner is unqualified in test.
If the real-time capability value does not meet the real-time target capability value in step 312, the air conditioner test is directly output to be unqualified. The test fail here means that the capability test fails.
In other preferred embodiments, in order to ensure the stability of the test and the accuracy of the test result, after the real-time capability value does not meet the real-time target capability value, whether the system is stable or not is judged, and after the system is stable, the process of adjusting the operation frequency of the compressor and/or the operation speed of the indoor fan is performed.
As a preferred embodiment, the following method is used to determine whether the system is operating stably:
judging whether the duration time of the air conditioner running at the fixed running current reaches a set time threshold value or not;
if so, judging that the system runs stably; otherwise, the system is judged to be unstable in operation.
