Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a method, apparatus, electronic device, and storage medium for detecting condenser blockage. Background Technology

[0002] Air conditioner outdoor units are usually installed outdoors. Over time, the condenser inevitably accumulates debris, leading to blockage. A clogged condenser increases air resistance in the air conditioning system, obstructing airflow and reducing the condenser's heat exchange efficiency, thus decreasing cooling or heating performance.

[0003] The existing method for detecting condenser blockage is to obtain the actual high-pressure value, actual exhaust temperature, and actual ambient temperature during air conditioner operation; then, based on the actual high-pressure value, find the actual saturation temperature and exhaust temperature reference value; next, based on the actual ambient temperature, find the saturation temperature reference value; and finally, based on the actual saturation temperature, actual exhaust temperature, saturation temperature reference value, and exhaust temperature reference value, determine the condenser blockage status.

[0004] The current method for detecting condenser blockage has the following problems: The reference values ​​obtained from the lookup table are pre-set and fixed. However, the saturation temperature and pressure will vary under different operating conditions and in different usage scenarios. For example, the boiling point of water at standard atmospheric pressure is 100℃, but in high-altitude areas, due to the reduced air pressure, the boiling point of water may drop to 98℃. The accuracy of the sensors varies, and the obtained temperature and pressure will deviate from the actual temperature and pressure. The sensors themselves also have inherent errors, which are unavoidable. Inaccurate actual temperature and pressure values ​​lead to unreliable reference values ​​and inaccurate detection results for condenser blockage. Summary of the Invention

[0005] This invention provides a method, apparatus, electronic device, and storage medium for detecting condenser blockage. The detection of condenser blockage is not affected by sensor error and accuracy, resulting in more accurate detection results.

[0006] According to one aspect of the present invention, a method for detecting condenser blockage is provided, the method being applied to an air conditioner, the method comprising:

[0007] Under the same operating conditions, the average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on is recorded.

[0008] The condenser's clogging status is determined based on the current average time and the previous average time under the same operating conditions.

[0009] Optionally, determining the condenser's fouling status based on the current average time and the previous average time under the same operating conditions includes:

[0010] Calculate the difference between the current average time and the previous average time under the same operating conditions;

[0011] When the difference is greater than the set value, it is determined that the condenser is clogged.

[0012] Optionally, before recording the current average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, under the same operating conditions, the method further includes:

[0013] Under the same operating conditions, the average time taken for the condenser to reach the set water temperature from the last time the air conditioner was turned on is recorded.

[0014] Optionally, the operating conditions include at least one of: ambient temperature, actual water temperature, and set water temperature.

[0015] Optionally, the ambient temperature range includes 0°C to 40°C.

[0016] Optionally, the actual water temperature range includes 0℃ to 40℃.

[0017] Optionally, the range of the set water temperature includes 0℃ to 40℃.

[0018] According to another aspect of the present invention, a condenser clogging detection device is provided, the condenser clogging detection device comprising:

[0019] The average time recording module is used to record the current average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, under the same operating conditions.

[0020] The dirt / clogging status determination module is used to determine the dirt / clogging status of the condenser based on the current average time and the previous average time under the same operating conditions.

[0022] One or more processors;

[0023] Memory, used to store one or more programs;

[0025] According to another aspect of the present invention, a computer-readable storage medium is also provided, on which a computer program is stored, which, when executed by a processor, implements the method as described in any embodiment of the present invention.

[0026] The technical solution of this invention involves recording the average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, under the same operating conditions. The condenser's clogging status is determined based on this average time and the previous average time under the same operating conditions. Detecting condenser clogging does not require sensors, thus avoiding the influence of sensor errors and accuracy. As the air conditioner runs longer and more sample data is recorded, the accuracy of condenser clogging detection increases, resulting in more accurate detection results. In summary, this invention solves the problem of inaccurate condenser clogging detection results in existing methods due to varying sensor accuracy and inherent sensor errors, leading to inaccurate actual temperature and pressure values ​​and unreliable baseline values.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] Figure 1 This is a flowchart of a condenser dirt blockage detection method according to an embodiment of the present invention, see reference. Figure 1 This invention provides a method for detecting condenser blockage, which can be executed by a condenser blockage detection device, which can be implemented by software and / or hardware. The condenser blockage detection method includes the following steps:

[0036] S110. Under the same operating conditions, record the average time it takes for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on.

[0037] Specifically, under the same operating conditions, such as ambient temperature, actual water temperature, and set water temperature, the average time f(t) taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on is recorded.

[0038] S120. Determine the condenser's clogging status based on the current average time and the previous average time under the same operating conditions.

[0039] Specifically, compare the current average time f(t) with the previous average time f(t-1) under the same operating conditions. If f(t-1)-f(t)<0, it means that as the current average time f(t) increases, the energy efficiency continues to decrease, showing a monotonically decreasing characteristic, which proves that the condenser is dirty and clogged.

[0040] The condenser clogging detection method in this embodiment of the invention determines the condenser clogging status by simulating and calculating the energy efficiency of the air conditioner under the same scenario and operating conditions. It compares the current average time with the previous average time under the same scenario and operating conditions. This method is unaffected by sensor errors and accuracy. The longer the air conditioner runs and the more sample data recorded, the higher the accuracy of condenser clogging detection. It can make corresponding judgments based on different usage scenarios and operating conditions, improving the accuracy of condenser clogging detection. It should be noted that different usage scenarios and operating conditions refer to different unit operating environments, such as high temperature or low temperature.

[0041] The condenser blockage detection method in this embodiment of the invention can ignore the impact of sensor accuracy and error on the judgment. The longer the air conditioner runs, the more sample data is recorded, and the higher the accuracy of condenser blockage detection. This detection method is applicable to any scenario and can ensure the accuracy of condenser blockage detection.

[0042] The technical solution of this invention involves recording the average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, under the same operating conditions. The condenser's clogging status is determined based on this average time and the previous average time under the same operating conditions. Detecting condenser clogging does not require sensors, thus avoiding the influence of sensor errors and accuracy. As the air conditioner runs longer and more sample data is recorded, the accuracy of condenser clogging detection increases, resulting in more accurate detection results. In summary, this invention solves the problem of inaccurate condenser clogging detection results in existing methods due to varying sensor accuracy and inherent sensor errors, leading to inaccurate actual temperature and pressure values ​​and unreliable baseline values.

[0043] Optionally, determining the condenser's fouling condition based on the current average time and the previous average time under the same operating conditions includes:

[0044] Calculate the difference between the current average time and the previous average time under the same operating conditions;

[0045] When the difference is greater than the set value, it is determined that the condenser is clogged.

[0046] Specifically, the difference between the current average time f(t) and the previous average time f(t-1) under the same operating conditions is calculated. If f(t-1)-f(t)<0, it means that as the current average time f(t) increases, the energy efficiency continues to decrease, showing a monotonically decreasing characteristic, which proves that the condenser is dirty and clogged.

[0047] Optionally, under the same operating conditions, before recording the current average time it takes for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, the following may also be included:

[0048] Under the same operating conditions, the average time taken for the condenser to reach the set water temperature from the last time the air conditioner was turned on is recorded.

[0049] Optionally, the operating conditions include at least one of: ambient temperature, actual water temperature, and set water temperature.

[0050] Optionally, the ambient temperature range includes 0℃ to 40℃.

[0051] Optionally, the actual water temperature range includes 0℃ to 40℃.

[0052] Optionally, the water temperature range can be set from 0℃ to 40℃.

[0053] Specifically, this embodiment exemplifies a method for detecting condenser blockage, and the specific implementation steps of this method are as follows:

[0054] f(t): represents the average time of 30 runs under the same operating conditions.

[0055] f(t-1): represents the average time of the previous 30 runs under the same operating conditions.

[0056] If f(t-1)-f(t)<0, it means that as the current average time f(t) increases, the time t value becomes smaller and the energy efficiency continues to decrease, showing a monotonically decreasing characteristic, which proves that the condenser is dirty and clogged.

[0057] Assuming the ambient temperature range of the equipment is 0–40℃, and the actual water temperature range is also 0–40℃, with each 5℃ interval representing one operating condition, the following average time table for operating condition records is obtained:

[0058]

[0059] Figure 2 This is a line graph showing the average time recorded according to an embodiment of the present invention, for reference. Figure 2 The ambient temperature was 20℃, the water temperature was 20℃, the water temperature was set to 10℃, the first average time was 30 minutes, the second average time was 30 minutes, the third average time was 33 minutes, and the fourth average time was 35 minutes.

[0060] according to The result shows that f(t-1)-f(t)<0. As the current average time f(t) increases, the time t value becomes smaller, indicating that the energy efficiency is continuously decreasing, which means that the condenser is considered to be dirty and clogged.

[0061] Figure 3 This is a schematic diagram of a condenser clogging detection device according to an embodiment of the present invention. (Refer to...) Figure 3 The present invention also provides a condenser clogging detection device, which includes:

[0062] The average time recording module 201 is used to record the current average time taken for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, under the same operating conditions.

[0063] The dirt and blockage determination module 202 is used to determine the dirt and blockage status of the condenser based on the current average time and the previous average time under the same operating conditions.

[0064] The above-mentioned condenser blockage detection device can perform the condenser blockage detection method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects for performing the condenser blockage detection method.

[0065] Continue to refer to Figure 3 Optionally, the dirt and blockage determination module 202 is also used to calculate the difference between the current average time and the previous average time under the same operating conditions;

[0066] When the difference is greater than the set value, it is determined that the condenser is clogged.

[0067] Optionally, under the same operating conditions, before recording the current average time it takes for the condenser to reach the set water temperature from the actual water temperature when the air conditioner is turned on, the following may also be included:

[0068] Under the same operating conditions, the average time taken for the condenser to reach the set water temperature from the last time the air conditioner was turned on is recorded.
