Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.
It should be noted that, the technical solutions of the embodiments of the present invention may be combined with each other, but it is necessary to be based on the fact that those skilled in the art can implement the embodiments, and when the technical solutions are contradictory or cannot be implemented, it should be considered that the combination of the technical solutions does not exist, and is not within the scope of protection required by 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 usually enters a fixed frequency mode, and the compressor operates at a fixed frequency and cannot adjust and change the frequency. Because of the air conditioning consistency problem, or by the production, test operating environment, etc., there may be cases where the test capability is not satisfactory. However, for the air conditioner, the air conditioner may still have a capacity lifting space, and the air conditioner is determined to be unqualified only if the frequency is fixed and the testing capacity cannot meet the requirement, so that the air conditioner is inaccurate in test and generates erroneous judgment, and the test passing rate is reduced. Without solving the technical problem, the invention considers that the operation parameters of the air conditioner are conditionally adjusted in the test process so as to improve the accuracy of the test result and the test passing rate.
Referring to fig. 1, a flowchart of a first embodiment of a test operation control method of an air conditioner according to the present invention is shown.
As shown in fig. 1, this embodiment performs air conditioner test operation control using the following procedure:
step 11: the air conditioner enters a capability test mode to acquire a real-time capability 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 characterization parameters and the acquisition method of the real-time capability value can be realized by adopting the prior art. As a preferred embodiment, the real-time capability value is represented by the temperature of the real-time air outlet of the indoor unit.
Step 12: when the real-time capability value does not meet the real-time target capability value, performing an adjustment 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 the 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 obtained 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 adjustment process is executed, and whether the tested capacity value can reach the target capacity value is determined through adjustment.
The specific adjustment process is to adjust the frequency of the compressor and/or the rotating speed of the indoor fan according to the system pressure value and the temperature value of the power module. 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 test process, and is generally a system high pressure value; the real-time power module temperature value refers to a temperature value of an air conditioner power module obtained in real time according to a set sampling frequency in a test process, and the two-value obtaining method 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. After the real-time system pressure value and the real-time power module temperature value are obtained, the real-time system pressure value and the real-time power module temperature value are respectively compared with a system pressure threshold value and a 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.
When the air conditioner enters a capacity test mode, if the real-time capacity value does not meet the real-time target capacity value, comparing the real-time system pressure value with a system pressure threshold value, comparing the real-time power module temperature value with a power module temperature threshold value, and adjusting the compressor running frequency and/or the indoor fan running rotating speed according to the comparison result; therefore, in the test operation process, the frequency of the compressor and/or the running rotating speed of the indoor fan are not fixed, but can be automatically adjusted, so that the problem that the system capacity is inconsistent with the actual capacity of a product due to the consistency problem of an air conditioner or the influence of production, test or test environment is solved, the accuracy of a test result is improved, and the test passing rate is increased; in addition, the frequency of the compressor and/or the running rotating speed of the indoor fan are/is not adjusted limitlessly, but are adjusted conditionally in a proper range based on the system pressure and the temperature of the power module, so that false detection and false judgment of forcing the product which cannot reach the standard 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 procedure:
acquiring real-time target operation parameters when the air conditioner enters a capacity test mode;
and determining a real-time target capacity value corresponding to the real-time target operation parameter according to the real-time target operation parameter and the known corresponding relation between the target operation parameter and the target capacity value. The corresponding relation between the target operation parameter and the target capacity value is stored in the air conditioner in advance.
Fig. 2 is a flowchart of a second embodiment of the air conditioner test operation control method according to the present invention, specifically, a flowchart of a specific example of adjusting the compressor operation frequency and/or the indoor fan operation rotation speed according to the comparison result of the real-time system pressure value and the system pressure threshold value and the comparison result of 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 the system pressure threshold value and the real-time system pressure value as a real-time pressure difference value, and acquiring a difference value between the power module temperature threshold value and the 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 and the first temperature difference are preset values, and can be determined according to structural parameters, performance parameters, testing conditions and the like of the air conditioner. For example, in a preferred embodiment, the first pressure differential is 0.4Mpa and the first temperature differential is 6 ℃.
Step 203: raising the operating frequency of the compressor, and controlling the compressor to operate at the raised operating frequency.
When it is determined in step 202 that the first condition that the real-time pressure difference value is greater than the first pressure difference value and the real-time temperature difference value is greater than the first temperature difference value is satisfied, it is indicated that there is a greater pressure difference value and a greater temperature difference value, and a greater capacity lifting space is provided.
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 value and the real-time temperature difference value 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 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 and the second temperature difference are preset values, and the first pressure difference and the second temperature difference are determined in the same way. 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 differential is 0.2Mpa and the second temperature differential 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 step 204 determines that 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, erroneous judgment of the test result caused by forced increase of the operation frequency of the compressor is avoided, and the operation rotating speed of the indoor fan is adjusted, so that small-amplitude adjustment of the system capacity is realized. Specifically, the running rotating speed of the indoor fan is increased, and the indoor fan is controlled to run at the increased running rotating speed, so that the air conditioner capacity is improved.
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 value and the real-time temperature difference value 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 compressor operating frequency and the indoor fan operating speed are kept unchanged.
When the real-time pressure difference value and the real-time temperature difference value meet the third condition, the pressure difference value or the temperature difference value is smaller, the capacity lifting space is smaller, the additional frequency or the wind speed adjustment of the fan is not executed, the operation frequency of the compressor and the operation rotating speed of the indoor fan are kept unchanged, and the inaccuracy of the test result caused by forced adjustment is avoided.
Fig. 3 is a flowchart of a third embodiment of the air conditioner test operation control method according to the present invention, specifically, a flowchart of a specific example of adjusting the compressor operation frequency and/or the indoor fan operation speed according to the comparison result of the real-time system pressure value and the system pressure threshold value and the comparison result of the real-time power module temperature value and the power module temperature threshold value.
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 the system pressure threshold value and the real-time system pressure value as a real-time pressure difference value, and acquiring a difference value between the power module temperature threshold value and the 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 the value of the first pressure difference and the first temperature difference can refer to the embodiment of fig. 2.
Step 303: raising the operating frequency of the compressor, and controlling the compressor to operate at the raised operating frequency.
When it is determined in step 302 that the first condition that the real-time pressure difference value is greater than the first pressure difference value and the real-time temperature difference value is greater than the first temperature difference value is satisfied, it is indicated that there is a greater pressure difference value and a greater temperature difference value, and a greater capacity lifting space is provided, at this time, the operating frequency of the compressor is raised, and the compressor is controlled to operate at the raised operating frequency, so as to achieve the purpose of improving 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.
In the process that the compressor operates at the increased operating 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 judging 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. The third pressure difference and the third temperature difference are preset values, and the third pressure difference and the third temperature difference are determined in the same mode as the first pressure difference and the second temperature difference. 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: the raising of the compressor operating frequency 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 smaller, the capacity-increasing space is smaller, and the increasing of the compressor operation frequency is stopped.
In other preferred embodiments, if the air conditioner capacity value does not meet the real-time target capacity value after stopping increasing the compressor operating frequency, a test result of failed air conditioner test 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 performed.
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 the second condition is satisfied, and corresponding control is performed 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 may 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 to continue the judgment and processing procedure of the next cycle.
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 the third condition is satisfied, and corresponding control is performed 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 compressor operating frequency and the indoor fan operating speed are kept unchanged. Then, go to step 313.
If step 307 determines 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 smaller, the capacity lifting space is smaller, and no additional frequency or fan wind speed adjustment is performed, but the compressor operating frequency and the indoor fan operating rotating speed are kept unchanged, so that 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 step 306 determines that 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, erroneous judgment of the test result caused by forced increase of the operation frequency of the compressor is avoided, and the operation rotating speed of the indoor fan is adjusted, so that small-amplitude adjustment of the system capacity is realized. Specifically, the running rotating speed of the indoor fan is increased, and the indoor fan is controlled to run at the increased running rotating speed, so that the air conditioner capacity is improved.
Step 310: and judging whether the added value reaches a set wind speed added threshold value. If yes, go to step 311; otherwise, the process of step 309 continues.
In the process that the indoor fan operates at the increased rotating speed, judging whether the increasing value of the rotating speed reaches a set wind speed increasing threshold value or not. Wherein, the wind speed increase threshold value is set to be a preset known value.
Step 311: stopping increasing the running rotating speed of the indoor fan.
If the increased value of the running speed of the indoor fan reaches the set wind speed increase threshold, the running speed of the indoor fan is stopped to be increased, the forced increase of the wind speed is avoided, the capacity is not beneficial to improvement, and the test result is inaccurate. Step 312 is then performed.
Step 312: the judgment capability value satisfies the real-time target capability value. If yes, go to step 313; otherwise, step 314 is performed.
And after stopping increasing the running rotating speed of the indoor fan, 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 meet the real-time target capability value,
step 313: and continuing the test.
If step 312 determines that the real-time capability value meets the real-time target capability value, then other testing procedures continue to be performed.
Step 314: the air conditioner is not qualified in test.
If step 312 determines that the real-time capability value does not meet the real-time target capability value, the direct output air conditioner fails the test. Here, failed test refers to failed capability test.
In other preferred embodiments, to ensure stability of the test and accuracy of the test result, after the real-time capability value does not meet the real-time target capability value, whether the system is running stably is first determined, and after the system is running stably, an adjustment process for the running frequency of the compressor and/or the running speed of the indoor fan is executed.
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 yes, judging that the system is stable in operation; otherwise, the system is judged to be unstable in operation.
