On the basis of the computer device 10 shown in fig. 2, a possible implementation manner of an air conditioner testing method is given below, specifically, fig. 3 is a schematic flow chart of the air conditioner testing method provided by the present invention, and referring to fig. 3, the air conditioner testing method may include the steps of:
and S1, acquiring a plurality of test items of the air conditioner, and the initial operating parameters and the operating parameters to be adjusted of the air conditioner under each test item.
The test items refer to different operation modes of the air conditioner, and are generally divided into a refrigerating mode and a heating mode, wherein the refrigerating mode comprises rated refrigeration, intermediate refrigeration, 25% refrigeration, minimum refrigeration, maximum refrigeration and the like, and the heating mode comprises rated heating, intermediate heating, 25% heating, minimum heating, low-temperature heating and the like.
The initial operation parameters refer to initial values of various operation parameters of the air conditioner, and the various operation parameters may include, but are not limited to, expansion valve step, indoor fan rotating speed, outdoor fan rotating speed, PFC switch, and the like. The initial operation parameters are set according to historical test data of the tested air conditioner, test data of other air conditioners similar to the type of the tested air conditioner, empirical data and the like, and the initial operation parameters of the air conditioner are different under different test items.
The operation parameters to be adjusted refer to operation parameters to be adjusted in the air conditioner testing process, such as the valve steps of the expansion valve, the rotating speed of the indoor fan, the rotating speed of the outdoor fan, the PFC switch and the like. Under different test items, the air conditioner has different operation parameters to be regulated, and meanwhile, the operation parameters to be regulated are set by a tester according to actual conditions.
And S2, acquiring a target test item and initial operation parameters and operation parameters to be adjusted corresponding to the target test item from the plurality of test items.
The target test item is one item that is currently required to be tested among a plurality of test items. For example, the target test item is rated refrigeration, the initial operation parameter is an initial value of each operation parameter of the air conditioner under the rated refrigeration, and the operation parameter to be adjusted is an operation parameter which needs to be adjusted under the rated refrigeration.
And S3, controlling the air conditioner to start to operate according to the initial operation parameters.
And S4, adjusting the operation parameters to be adjusted until the energy efficiency ratio of the air conditioner is maximum, and acquiring the operation condition parameters of the air conditioner.
The Energy Efficiency Ratio (EER) is a Ratio of the amount of cooling or heating provided by the air conditioner to the amount of Energy consumed by the air conditioner itself.
The operation condition parameters refer to the actual values of the operation parameters currently collected by the air conditioner and the actual values of the environmental parameters currently collected by the test board.
And S5, when the operation condition parameters meet the set conditions, acquiring the actual operation parameters of the air conditioner in the period with the maximum energy efficiency ratio.
The set conditions include that after the air conditioner reaches the maximum energy efficiency ratio, the working condition of the test bench is in place within a period of time (for example, 5min), the operation of the tested air conditioner is stable, the test data of the tested air conditioner is stable, the recording condition of the test data is reached, and the like.
The actual operation parameter of the air conditioner in the time period with the maximum energy efficiency ratio can be the actual operation parameter of the air conditioner at the time with the maximum energy efficiency ratio; or may be an actual operating parameter of the air conditioner during a period of time (e.g., 3min) from the time when the energy efficiency ratio is maximized to the time before the time. For example, if the time when the energy efficiency ratio is maximum is 14:45, the actual operation parameter of the time period when the energy efficiency ratio is maximum may be the actual operation parameter of the air conditioner at 14:45, or may be the actual operation parameter of the air conditioner within 3min of 14:42 to 14: 45.
And S6, obtaining the recommended operation parameters of the air conditioner under the target test item according to the actual operation parameters.
If the actual operation parameter is the actual operation parameter of the air conditioner at the moment when the energy efficiency ratio is maximum, directly taking the actual operation parameter as a recommended operation parameter; and if the actual operation parameter is the actual operation parameter of the air conditioner within a period of time (for example, 3min) before the moment when the energy efficiency ratio is maximum, taking the average value of the actual operation parameters within the period of time as the recommended operation parameter.
After the step S6 is completed, that is, the recommended operating parameters of the air conditioner under the target test item are obtained, if there are unfinished test items in the plurality of test items, the test is required to be continued, and therefore, the air conditioner testing method further includes:
and repeatedly executing the steps from S2 to S6 until the recommended operating parameters of the air conditioner under each test item are obtained.
It should be noted that the above-mentioned S1-S6 are only used for numbering the steps, and do not limit the execution order of the steps, and those skilled in the art may also use other manners to number the steps, such as a parameter obtaining step, a parameter adjusting step, and the like. In other words, the air conditioner testing method is not limited to be performed in the order of S1 to S6, and the execution order of the steps can be flexibly adjusted according to actual situations.
Optionally, before step S1, the air conditioner testing method may further include the steps of:
and establishing a test list, wherein the test list comprises a plurality of test items of the air conditioner, and the initial operating parameters and the operating parameters to be adjusted of the air conditioner under each test item.
Meanwhile, the test sequence of the plurality of test items in the test list is determined, and usually the cooling mode is tested first, and then the heating mode is tested, for example, the test list is shown in table 1 below:
TABLE 1
Figure BDA0002471540810000091
The test sequence of each test item is from left to right, namely, the test is performed from rated refrigeration to low-temperature heating. The initial operating parameters are initial values of the expansion valve steps, the indoor fan speed, the outdoor fan speed, and the like, which are not shown in the table above. The operation parameters to be adjusted refer to the contents selected in the table, for example, the test item is rated refrigeration, and the corresponding operation parameters to be adjusted are expansion valve steps and PFC switches; the test item is 25% refrigeration, and the corresponding operation parameter to be adjusted is the valve step of the expansion valve and the like.
Optionally, after step S6, that is, after obtaining the recommended operating parameters of the air conditioner under the target test item, the air conditioner testing method may further include the steps of:
and updating the recommended operating parameters of the air conditioner under the target test item into the test list, namely updating the initial operating parameters of the air conditioner under the target test item into the recommended operating parameters.

For example, assume that the first capacity value is Q1Target capacity value is QTargetThen, the first preset condition may be: q1≥QTargetOr is or
Figure BDA0002471540810000101
Wherein m is a constant, and can be 3% to 4%.

In one possible scenario, after the air conditioner reaches the maximum energy efficiency ratio, if the adjustment of the operation parameter to be adjusted is continued, the energy efficiency ratio may be gradually decreased, and therefore, referring to fig. 5, after the sub-step S44, the step S4 may further include the following sub-steps:
and S45, adjusting the rotating speed of the fan according to a preset rule to enable the difference value between the current energy efficiency ratio and the last energy efficiency ratio of the air conditioner to be within a first preset range.
The first preset range may be a specific value or a value range, for example, a difference between the current energy efficiency ratio and the last energy efficiency ratio is 0.03, or a difference between the current energy efficiency ratio and the last energy efficiency ratio is less than 0.03.
The fan rotation speed in this embodiment includes an indoor fan rotation speed and an outdoor fan rotation speed, and step S45 may include:
and S451, setting the preset wind speed ascending and descending mark and the current value of the counter to be 0. Assuming that the wind speed ascending and descending identifier is X and the current value of the counter is N, X is 0 and N is 0.

For example, the first preset rotation speed value is 50rpm, and the second preset rotation speed value is 20 rpm. In practical application, a user can self-define the first preset rotating speed value and the second preset rotating speed value according to practical situations, and the limitation is not made herein.
And S453, adding 1 to the current value of the counter, and measuring and calculating the current energy efficiency ratio of the air conditioner after waiting for the preset time.
The preset time can be 1min, 5min or 10min, and the like, and the accurate energy efficiency ratio of the air conditioner can be measured and calculated only when the air conditioner runs stably.
And S454, judging whether the difference value between the current energy efficiency ratio and the last energy efficiency ratio of the air conditioner is within a first preset range.
If not, returning to execute the step S452; if yes, go to step S455.
S455, it is determined whether the current value of the counter is greater than a preset value. The preset value may be 1, 2, or 3, and the user may customize the preset value according to the actual situation, which is not limited herein.

The second preset condition may be the same as the first preset condition or different from the first preset condition.
For example, assume the second capacity value is Q2Target capacity value is QTargetThen, the second preset condition may be: q2≥QTargetOr is or
