Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.
The following describes an operation capability detection method and system of an air conditioner according to an embodiment of the present application with reference to the accompanying drawings.
Fig. 1 is a flowchart of an operation capability detection method of an air conditioner according to an embodiment of the present application. As shown in fig. 1, a method for detecting an operation capability of an air conditioner according to an embodiment of the present application includes the steps of:
s101: in a preset time period, acquiring an air conditioner operation parameter and a plurality of capacity output values which are monitored at intervals of first preset time to obtain a first capacity output value sequence, wherein the air conditioner operation parameter comprises indoor temperature. Wherein the predetermined period of time is, for example, 2 minutes.
As a specific example, as shown in fig. 2, the first predetermined time is, for example, x seconds. X is, for example, 1 second, 2 seconds, 3 seconds, or the like.
The air conditioner operation parameters may include, but are not limited to, in addition to the indoor temperature T1 (also referred to as the indoor ambient temperature T1): the real-time outdoor environment temperature T2 of air conditioner, the compressor running frequency W, the opening Z of electronic expansion valve, the rotating speed of indoor fan A r/min, the rotating speed of outdoor fan Br/min.
As shown in fig. 4, the schematic diagram of an air conditioner is shown, the air conditioner includes an indoor unit portion at an indoor side and an outdoor unit portion at an outdoor side, wherein, in fig. 4, reference numerals respectively denote: the compressor 1, the four-way valve 2, the outdoor fan 31, the outdoor heat exchanger 32, the throttling element 4, the indoor fan 51, the indoor heat exchanger 52 and the numbers (i) to (12) are all temperature sensors arranged at different temperature monitoring points and the compressor running power W.
The air conditioner operation parameters can be acquired through corresponding sensors and the like, and the corresponding capacity output value at the current moment can be obtained through a calculation mode according to the operation parameters.
The method for detecting the operation capacity of the air conditioner can be applied to capacity detection when the air conditioner enters an unstable working state after being started. For example: when the air conditioner is started for the first time, a user is required to input information such as the volume V of the space used by the air conditioner, the material of the enclosure, the size of a door and a window and the like according to the actual condition of the user. Two preconditions are provided for entering unsteady state capacity detection, one is that the air conditioner does not carry out capacity detection for a long time; and secondly, the user requires capability detection. At this time, the operation parameter value and the real-time monitoring capability output value Qi are taken and recorded every x seconds, for example: if i is less than or equal to n, n Qi form a first capability output value sequence, and n is a positive integer.
S102: and judging whether the temperature difference between the indoor temperature and the set temperature is smaller than a first preset temperature difference.
As shown in fig. 2, during operation, it is detected whether the absolute value of the difference between the measured indoor ambient temperature T1 of the air conditioner and the set temperature Ts of the air conditioner is less than a first predetermined temperature difference Δ T, that is: judging whether | T1-Ts | < Δ T is true, wherein the first preset temperature difference Δ T is related to the set temperature Ts of the air conditioner, if yes, entering step S103, and storing the related value in a storage or uploading the related value to a cloud platform; if not, the air conditioner continues to operate for a preset time and then detects again.
S103: and if so, acquiring a second capacity output value sequence monitored at a third preset time interval in a second preset time period after the second preset time. Further, when the temperature difference between the indoor temperature and the set temperature is not less than the first predetermined temperature difference, the process returns to S101 to re-detect.
As shown in fig. 2, the second predetermined time is N × Y seconds, and the third predetermined time is Y seconds. Namely: when Y seconds are called after N X Y seconds, N capacity output values monitored from 2Y seconds to N X Y seconds are respectively expressed as: q11, Q12 to Q1N1, Q2N2, Q22 to Q21, wherein N1+ N2 ═ N. In a specific example, Y is, for example, 2 seconds, N is, for example, 10, and N1 and N2 are, for example, 5, respectively. Thus, Q11, Q12 through Q15, Q21, Q22 through Q25 constitute a second capability output value sequence.
S104: and judging whether the second capacity output value sequence meets a preset condition.
In a specific example, a running capacity average of a previous portion in the second series of capacity output values is calculated; and calculating the running capacity average value of the rest part in the second capacity output value sequence, judging whether the absolute value of the difference value between the running capacity average value of the previous part and the running capacity average value of the rest part is smaller than a preset capacity difference value, and if so, judging that the second capacity output value sequence meets a preset condition.
Specifically, as shown in fig. 2, with Q11, Q12 to Q1n1 as the operational capability of the previous part in the second capability output value sequence, and Q2n2, Q22 to Q21 as the operational capability of the remaining part in the second capability output value sequence, then: judging whether | (Q11+ Q12+ … + Q1n)/n1- (Q21+ Q22+ … + Q2n2)/n2| < Δ Q is true, if true, determining that the capability output is stable, namely: if the predetermined condition is satisfied, step S105 is performed, where Δ Q is a predetermined capacity difference, which may be understood as a tolerance range, and the value thereof is related to the capacity of real-time monitoring, and the related value is stored in the storage and uploaded to the cloud platform.
S105: if so, an average capability value is calculated from the first sequence of capability output values.
Wherein the average capacity value

x is a first predetermined time, namely: time interval of monitoring.
The stored running time from the air conditioner can also be called, such as: until the time when the determination capability output is stable, when t is 0, for example: and (3) calculating the average operation capacity of the air conditioner during the non-steady operation period according to the formula.
S106: and determining whether the operation capacity of the air conditioner reaches the standard or not according to the average capacity value.
And judging whether the operation capacity of the air conditioner reaches the standard, judging the ranking range of the operation capacity of the air conditioner, and knowing whether the operation capacity is qualified. For example:
determining whether the operation capacity of the air conditioner reaches the standard according to the average capacity value, wherein the step of determining whether the operation capacity of the air conditioner reaches the standard comprises the following steps: judging the capacity area of the average capacity value in a preset capacity area table; and determining the operation capacity grade of the air conditioner according to the capacity area of the average capacity value in the preset capacity area table. Fig. 4 is a schematic diagram of a preset capability area table.
Specifically, the initial indoor environment temperature is T1, the outdoor environment temperature is T2, and in the environment with the space volume of V, the average unsteady state operation capacity interval and the capacity ranking interval of the relevant history of the same machine type in the interval, and the capacity output can tolerate the minimum value Qmin (namely, the preset normal capacity lower limit) and the like.
Comparing the areas where the average operation capacity of the air conditioner is located during the unsteady state operation, namely: a ranking range of average run-time capabilities is determined.
As shown in FIG. 3, the capacity output is greater than the lower limit Q1L of the capacity region and less than Q2L, indicating that the capacity output is greater than Q1% for machines of the same model; the capacity output is greater than the lower limit Q2L of the capacity region and less than Q3L, which shows that the capacity output is higher than Q2% of machines of the same model; the capacity output is greater than the lower limit Q3L of the capacity region and less than Q4L, which shows that the capacity output is higher than Q3% of machines of the same model; the capacity output is greater than the lower limit Q4L of the capacity region and less than Q5L, which shows that the capacity output is higher than Q4% of machines of the same model; the capacity output is larger than the lower limit Q5L of the capacity region, which shows that the capacity output is higher than Q5% of machines of the same model, wherein Q1%, Q2%, Q3%, Q4% and Q5% are respectively as follows: 15%, 35%, 55%, 75%, 95%. The lower limit of the capacity of each area is different from the type of the air conditioner, the size of the match, and the like. In this way, the operation capability level of the air conditioner is also determined.
Determining whether the operation capacity of the air conditioner reaches the standard according to the average capacity value, and further comprising the following steps: judging whether the average capacity value is smaller than a preset normal capacity lower limit or not; and if so, judging that the operation capacity of the air conditioner does not reach the standard.
Referring to fig. 2 again, comparing the unstable average output capacity with the minimum tolerable capacity Qmin of capacity output, if Q > Qmin is satisfied, it indicates that the unstable capacity output of the air conditioner is normal, and if Q > Qmin is not satisfied, it indicates that the unstable capacity output of the air conditioner is not normal.
It should be noted that the preset capability area table and the preset lower limit of normal capability are provided by the cloud server.
The method for detecting the operation capacity of the air conditioner can be used for detecting the operation capacity of the air conditioner on line and quantitatively judging whether the operation capacity output of the air conditioner is qualified or not. Due to the adoption of quantitative judgment modes such as capability value comparison and the like, faults which are difficult to observe in the early stage can be eliminated by using the detection of capability and energy efficiency, so that the qualification rate of finished air-conditioners is effectively improved, and the quality of the air-conditioners is improved.
Referring to fig. 2, in an embodiment of the present application, before determining whether a temperature difference between an indoor temperature and a set temperature is less than a predetermined temperature difference, the method for detecting an operation capability of an air conditioner further includes: calculating the average value of the outdoor temperatures monitored at every interval of the first preset time; judging whether the temperature difference between the current outdoor temperature and the average value of the outdoor temperatures is smaller than a second preset temperature difference or not; if so, executing the step of judging whether the temperature difference between the indoor temperature and the set temperature is smaller than the first preset temperature difference, otherwise, exiting the operation capacity detection of the air conditioner.
That is, every xs is started after the detection starts for N4 × s, temperature values T2x and T22x … T2N4 × of the outdoor ambient temperature T2 at x seconds, 2 × seconds to N4 × seconds are retrieved, T2avg is taken as (T2x + T22x + … + T2N4 ×)/N4, and it is determined whether | T2-T2avg | < Δ T2 is established, where the value of Δ T2 is related to T2avg, and the related values are stored in the storage or the cloud platform. If so, continuing to operate; if not, the unsteady state capability detection is stopped, and the detection can be restarted after the next time the air conditioner starts to operate again.
