Description

Technical Field

[0002] The outdoor unit of the air conditioner is usually installed outdoors. After long-term use, the air conditioner condenser will inevitably absorb some debris, causing dirt and blockage. Condenser blockage will increase the air resistance of the air conditioning system, resulting in obstruction of air flow, which will reduce the heat exchange efficiency of the condenser and reduce the cooling or heating effect.

[0003] The existing condenser dirty blockage detection method is to obtain the actual high-pressure pressure value, actual exhaust temperature and actual ambient temperature when the air conditioner is running; and find the actual saturation temperature and exhaust temperature reference value based on the actual high-pressure pressure value; then find the saturation temperature reference value based on the actual ambient temperature; finally, determine the dirty blockage of the condenser based on the actual saturation temperature, actual exhaust temperature, saturation temperature reference value and exhaust temperature reference value.

[0004] The following problems exist in this method for detecting dirty and blocked condensers: the reference value obtained by looking up the table is preset and fixed in advance, and the saturation temperature and saturation pressure will be different under different usage scenarios and working conditions. For example, the boiling point of water under standard atmospheric pressure is 100°C, but in plateau areas, due to the decrease in air pressure, the boiling point of water may drop to 98°C. The accuracy of the sensors is different, and there will be deviations between the obtained temperature and pressure and the actual temperature and pressure; the sensors themselves will also have certain errors, which are inevitable; the actual temperature and pressure values ​​obtained are inaccurate, and the reference values ​​obtained are unreliable, and the detection results of dirty and blocked condensers are inaccurate.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] Figure 1 is a flow chart of a condenser dirty blockage detection method provided according to an embodiment of the present invention, referring to Figure 1 The embodiment of the present invention provides a method for detecting dirty condenser blockage, which can be performed by a dirty condenser blockage detection device, which can be implemented by software and / or hardware. The dirty condenser blockage detection method includes the following steps:

[0036] S110: Under the same operating conditions, the air conditioner records the current average time taken for the condenser's actual water temperature to reach the set water temperature from when the air conditioner is turned on.

[0037] Specifically, the air conditioner is under the same operating conditions, for example, the operating conditions may be ambient temperature, actual water temperature, and set water temperature, and the current 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, determining the dirtiness and blockage of the condenser according to the current average time and the previous average time under the same operating condition.

[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 with the increase of the current average time f(t), the energy efficiency has been decreasing, showing a monotonically decreasing characteristic, which proves that the condenser is dirty and blocked.

[0040] The condenser dirty blockage detection method in the embodiment of the present invention simulates and calculates the energy efficiency of the air conditioner operation under the same scenario and working conditions, and compares the current average time with the previous average time under the same scenario and working conditions to determine the dirty blockage of the condenser. This method is not affected by the error and accuracy of the sensor. As the air conditioner runs longer, the more sample data is recorded, and the higher the accuracy of determining whether the condenser is dirty or blocked. It can make corresponding judgments based on different usage scenarios and different working conditions, thereby improving the accuracy of determining whether the condenser is dirty or blocked. It should be noted that different usage scenarios and different working conditions refer to different unit operating environments, such as high temperature or low temperature.

[0041] The condenser dirty blockage detection method in the embodiment of the present invention can ignore the influence 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 the condenser dirty blockage detection. The detection method is applicable to any scenario and can ensure the accuracy of the condenser dirty blockage detection.

[0042] According to the technical solution of the embodiment of the present invention, the air conditioner records 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, and determines the dirty and blocked condition of the condenser based on the current average time and the previous average time under the same operating conditions; the dirty and blocked condition of the condenser does not require the use of a sensor, and is not affected by the error and accuracy of the sensor. As the air conditioner runs longer, the more sample data is recorded, and the higher the accuracy of judging the dirty and blocked condenser, the more accurate the detection result of the dirty and blocked condenser is. In summary, the present invention solves the problem that the existing condenser dirty and blocked detection method has inaccurate actual temperature and pressure values ​​due to the different accuracy of the sensor, the sensor itself also has certain errors, the obtained reference value is unreliable, and the detection result of the dirty and blocked condenser is inaccurate.

[0043] Optionally, determining the dirty and blocked condition of the condenser according to the current average time and the previous average time under the same operating condition 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 dirty and blocked.

[0046] Specifically, the current average time f(t) is subtracted from the previous average time f(t-1) under the same operating conditions. If f(t-1)-f(t)<0, it means that with the increase of the current average time f(t), the energy efficiency has been decreasing, showing a monotonically decreasing characteristic, which proves that the condenser is dirty and blocked.

[0047] Optionally, under the same operating conditions, the air conditioner further includes recording the current average time taken for the actual water temperature of the condenser to reach the set water temperature from when the air conditioner is turned on:

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

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

[0050] Optionally, the range of the ambient temperature includes 0°C to 40°C.

[0051] Optionally, the actual water temperature ranges from 0°C to 40°C.

[0052] Optionally, the water temperature is set in a range of 0°C to 40°C.

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

[0054] f(t): represents the average time of 30 running times under the same working conditions.

[0055] f(t-1): represents the average value of the last 30 running times under the same working 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, the energy efficiency decreases, and it shows a monotonically decreasing characteristic, which proves that the condenser is dirty and blocked.

[0057] Assuming that the ambient temperature range of the equipment is 0-40℃, the actual water temperature range is 0-40℃, and every 5℃ is a working condition, the following working condition record average time table is obtained:

[0058]

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

[0060] according to It is concluded that f(t-1)-f(t)<0. As the current average time f(t) increases, the time t value becomes smaller, and the energy efficiency continues to decrease, which means that the condenser is dirty and blocked.

[0061] Figure 3 is a schematic diagram of a condenser dirty blockage detection device provided according to an embodiment of the present invention, with reference to Figure 3 The embodiment of the present invention further provides a condenser dirty blockage detection device, the condenser dirty blockage detection device comprising:

[0062] The average time recording module 201 is used for recording the current average time taken for the actual water temperature of 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 dirty and blocked condition determination module 202 is used to determine the dirty and blocked condition of the condenser according to the current average time and the previous average time under the same operating condition.

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

[0065] Continue to refer Figure 3 , Optionally, the dirty and blocked condition determination module 202 is further used to calculate the difference between the current average time and the previous average time under the same operating condition;

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

[0067] Optionally, under the same operating conditions, the air conditioner further includes recording the current average time taken for the actual water temperature of the condenser to reach the set water temperature from when the air conditioner is turned on:

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