[0059] In related technologies, after the air conditioner 200 has been running for a long experimental period, the corrosion degree of the components is analyzed to obtain corrosion data of the components. However, the obtained corrosion data cannot accurately reflect the corrosion process of the components during the experimental period, which affects the accuracy of the air conditioner anti-corrosion scheme.
[0060] Therefore, this invention proposes a monitoring device 100 for use in an air conditioner 200, which can realize online monitoring of the actual state of the air conditioner components during the corrosion process, thereby improving the accuracy of the corrosion process state analysis of the air conditioner components and thus improving the accuracy of the formulated air conditioner anti-corrosion scheme. The structure of the monitoring device 100 will be described below by way of an embodiment.
[0061] Reference Figure 1 The monitoring device 100 includes a data acquisition component, a fixture 101, and a data processor 103. The data acquisition component includes at least one probe 102, with a detection electrode disposed within the probe 102. The material of the detection electrode is the same as that of the component under test in the air conditioner 200. The fixture 101 is used to mount the probe 102 to the operating environment of the component under test. The data processor 103 is electrically connected to the probe 102 and is used to process the detection signal from the probe 102 to obtain a target signal, thereby determining the corrosion status information of the component under test in the operating environment based on the target signal.
[0062] In this embodiment, the monitoring device 100 is applied to the air conditioner 200, which can be a split-type air conditioner or an integrated air conditioner. For example, the air conditioner 200 may include an indoor unit and an outdoor unit, or it may be a window air conditioner. The air conditioner 200 may include air conditioning components such as a heat exchanger 250, a throttling device, a fan, a compressor, and connecting pipes.
[0063] The component to be tested is an air conditioning component that requires corrosion detection. In this embodiment, the component to be tested includes the refrigerant pipe in the heat exchanger 250 of the air conditioner 200, and the corrosion status information can be information indicating the electrochemical corrosion status on the refrigerant pipe. In some other embodiments, the component to be tested may also be a fan, etc.
[0064] The detection electrode is an electrode made of the material of the component under test. In this embodiment, the component under test includes a refrigerant pipe in the heat exchanger 250, and the refrigerant pipe is made of copper, so the detection electrode is a copper electrode. The heat exchanger 250 can be an indoor heat exchanger 250 or an outdoor heat exchanger 250. In other embodiments, the refrigerant pipe is made of aluminum, so the detection electrode can also be an aluminum electrode. In a feasible implementation, the detection electrode includes a comb-tooth electrode, and both the component under test and the comb-tooth electrode are made of metal, so the electrochemical corrosion process of the component under test during the operation of the air conditioner 200 can be monitored based on the comb-tooth electrode.
[0065] The probe 102 is a measuring tool obtained by encapsulating a detection unit (electrode or sensor, etc.). The probe 102 is energized during detection, and the electrical signal supplied to it can be alternating current (AC) or direct current (DC). In this embodiment, the electrical signal supplied to the probe 102 is AC, which has higher current sensitivity than DC. When the probe 102 is in the detection state, the output detection signal will differ depending on the state of the object being detected. Based on this, the output detection signal of the probe 102 can accurately characterize the state of the object being detected. For example, when a detection electrode is provided in the probe 102, and the object being detected is the degree of corrosion of the detection electrode itself, different degrees of corrosion will result in different output detection signals (e.g., voltage signals) from the probe 102. Similarly, when a temperature sensor is provided in the probe 102, and the object being detected is temperature, different temperatures will result in different output detection signals (e.g., voltage signals) from the probe 102.
[0066] The data acquisition component may include one or at least two probes 102. When the data acquisition component includes one probe 102, a detection electrode is disposed within the probe 102. When the data acquisition component includes at least two probes 102, one or more probes 102 may contain detection electrodes, wherein other corrosion detection-related sensors may be disposed within probes 102 that do not contain detection electrodes. The number and type of probes 102 installed in the operating environment of the component under test in the data acquisition component can be selected according to the actual needs of corrosion detection of the component under test.
[0067] The fixture 101 is an installation structure for mounting the probe 102 from the data acquisition component to the operating environment of the component under test. The operating environment here refers to the area near the component under test. The fixture 101 has mounting positions corresponding to the probe 102, which can be mounted on the fixture 101. When the data acquisition component includes more than one probe 102, different probes 102 can be placed in different mounting positions. The fixture 101 can be mounted on the component under test, or it can be mounted on the body of the air conditioner 200 where the component under test is located, or it can be mounted outside the air conditioner 200 with the portion containing the probe 102 extending into the body of the air conditioner 200. The fixture 101 can be installed in the environment where the air conditioner 200 is located in a detachable or non-detachable manner, for example, by plugging, snapping, screw fixing, welding, etc., in the environment where the air conditioner 200 is located (including the air conditioner 200 or its exterior). The probe 102 can be fixedly or detachably mounted on the clamp 101. The clamp 101 is a structure made of an elastic material, which may include ABS plastic (a terpolymer of acrylonitrile, butadiene, and styrene monomers) or resin, etc. The specific structure of the clamp 101 can be seen in the following embodiment.
[0068] The data processor 103 is a device for processing the detection signal output by the probe 102 to form a target signal. The data processor 103 can be installed on the air conditioner 200 or set up independently of the air conditioner 200. The data processor 103 may include a transmitter or a CPU, etc. When the data acquisition component includes more than one probe 102, all of the probes 102 are electrically connected to the data processor 103.
[0069] The data processor 103 can acquire and process the detection signal from the probe 102 in real time or at set intervals, or when data acquisition conditions are met (e.g., receiving a data acquisition command). In one implementation, the target signal is corrosion state information, and the data processor 103 can directly analyze the detection signal output by the probe 102 to obtain the corrosion state information. In another implementation, the target signal is a signal for the analysis device 500 to analyze and obtain corrosion state information. The data processor 103 can process the detection signal output by the probe 102 into a target signal and then send the target signal to the analysis device 500. The analysis device 500 analyzes the received target signal to obtain the corrosion state information of the component under test in the operating environment. The analysis device 500 can be part of the monitoring device 100, for example, it can be integrated with the data processor 103, or it can be an external device to the monitoring device 100. The analysis device 500 can be a local device in the area where the air conditioner 200 is located, or it can be a cloud platform. The data processor 103 and the analysis device 500 can transmit signals via wired or wireless communication.
[0070] When the data acquisition component includes at least two probes 102, the data processor 103 converts the detection signals of different probes 102 into corresponding target signals to obtain at least two target signals, so as to determine the corrosion status information of the component under test in the operating environment based on the at least two target signals.
[0071] The corrosion status information may include at least one of the following: corrosion behavior information, corrosion mechanism information, corrosion rate, corrosion amount, corrosion rate, etc. The corrosion status information may include information representing the real-time corrosion status of the component under test at one or more moments and / or information representing the corrosion status of the component under test over a period of time or during different air conditioning operating periods.
[0072] During the test, the probe 102 in the data acquisition component can be mounted on the fixture 101, which can be installed in the environment where the air conditioner 200 is located. The probe 102 is located in the operating environment of the component under test. The data processor 103 can be placed or installed in the environment where the air conditioner 200 is located. During the operation of the air conditioner 200 with preset operating parameters, the data processor 103 can acquire the detection signal of the probe 102 in real time and process the detection signal into a target signal. The target signal is then sent to the analysis device 500 in real time. The analysis device 500 can record the received target signal and determine the corrosion status information of the component under test in the operating environment based on the recorded target signal. The preset operating parameters are the air conditioner operating parameters set according to the air conditioner operating conditions corresponding to the corrosion test requirements of the component under test. The analysis device 500 can analyze the change pattern of the received target signal and analyze the corrosion behavior information of the component under test in different time periods within the operating cycle of the air conditioner 200 based on the change pattern of the target signal corresponding to the detection electrode. The corrosion status information may include corrosion behavior information, which may include whether corrosion has occurred, the time when corrosion occurred, the time when the corrosion rate is greater than the preset rate, etc.
[0073] In this embodiment, the component under test includes the refrigerant pipe of the heat exchanger 250. During the operation of the air conditioner 200 with preset operating parameters, the fan corresponding to the heat exchanger 250 is in the on state. The fan can drive the air in the environment where the air conditioner 200 is located to blow towards the heat exchanger 250 and the probe 102. Based on this, the probe 102 can simulate the state of electrochemical corrosion of the heat exchanger 250 under the influence of air temperature, humidity, sulfur dioxide, carbon dioxide and other components. Then, through the cooperation of the data processor 103, the probe 102 and the fixture 101, the actual state of the refrigerant pipe in the heat exchanger 250 during the electrochemical corrosion process can be monitored online.
[0074] This embodiment proposes a monitoring device 100 for use in an air conditioner 200. A probe electrode is installed in the operating environment of the component under test within the air conditioner 200 using a clamp 101. A data processor 103 processes the detection signal from the probe electrode. Since the probe electrode is made of the same material as the component under test, the results obtained from processing the detection signal can accurately reflect the actual corrosion state of the component under test at any given moment during the corrosion process in the operating environment. Based on this, online monitoring of the corrosion state of the component under test can be achieved, effectively improving the accuracy of the corrosion process state analysis of the air conditioner components, thereby enhancing the accuracy of the formulated air conditioner corrosion prevention scheme.
[0075] In one embodiment, combined with Figure 8 The data acquisition component includes at least two probes 102, and an environmental sensor is installed in at least one of the probes 102.
[0076] Environmental sensors can be one of the following: temperature sensor, humidity sensor, carbon dioxide sensor, sulfur dioxide sensor, etc.
[0077] In this embodiment, the probe 102 with the detection electrode is defined as the first probe, and the probe 102 with the environmental sensor is defined as the second probe. Therefore, the data acquisition component may include at least one first probe and at least one second probe. When there is more than one second probe, the environmental sensors installed on each second probe may be different. The fixture 101 can mount both the first and second probes in the operating environment of the component under test.
[0078] The number of second probes installed in the operating environment of the component under test and the type of environmental sensor therein can be set according to the corrosion detection requirements of the component under test.
[0079] In this embodiment, the corrosion status information may also include information on the mechanism of the corrosion performance of the component under test in the operating environment.
[0080] The data processor 103 can process the detection signal from the first probe to obtain a first target signal, and the data processor 103 can process the detection signal from the second probe to obtain a second target signal, so as to determine the corrosion status information of the component under test based on the first target signal and the second target signal. The above-mentioned at least two target signals include the first target signal and the second target signal here.
[0081] In this embodiment, the monitoring device 100 is equipped with more than one probe 102. In addition to simulating the corrosion process of the component under test through the detection electrode, it can also effectively monitor the environmental state of the component under test during the corrosion process based on the detection signal of the environmental sensor. It can accurately analyze the influence and mechanism of the operating environment of the component under test on the corrosion performance of the component under test, and further improve the accuracy of the corrosion process state analysis of the air conditioning component.
[0082] In other embodiments, at least two probes 102 may also be the first probe.
[0083] In one embodiment, combined with Figure 1 The data processor 103 includes a transmitter, and the target signal includes a standard electrical signal. The transmitter is used to process the detection signal of the probe 102 into a standard electrical signal and send the standard electrical signal to the analysis device 500 so that the analysis device 500 can determine the corrosion state information based on the standard electrical signal.
[0084] Standard electrical signals include standard current signals or standard voltage signals.
[0085] In this embodiment, the analysis device 500 is a cloud platform.
[0086] In this embodiment, the monitoring process of the monitoring device 100 is as follows: Figure 1 As shown.
[0087] In this embodiment, the signal detected by the probe 102 is processed into a standard electrical signal by the cooperation of the transmitter and the probe 102, which facilitates long-distance transmission and improves the compatibility of the data processor 103 with different analysis devices 500. This is beneficial to further improve the efficiency and convenience of corrosion process state analysis of air conditioning components.
[0088] In other embodiments, the analysis device 500 may also be a local computer or the like.
[0089] In one embodiment, combined with Figures 10 to 11 The component under test includes a refrigerant pipe in a heat exchanger 250, wherein the heat exchanger 250 may include a refrigerant pipe and fins disposed on the surface of the refrigerant pipe. The refrigerant pipe may include at least two pipe segments connected end-to-end, and the at least two pipe segments are arranged at intervals along a first preset direction. When the detection electrode is installed in the operating environment of the component under test, the detection electrode may be attached to the fins. Based on this, the data processor 103 processes the detection signal of the probe 102 to obtain the target signal as follows: a temperature compensation value is determined based on the temperature difference between the ambient temperature of the environment where the air conditioner 200 is located and the refrigerant temperature in the refrigerant pipe; the detection signal of the probe 102 is corrected according to the signal correction parameters corresponding to the temperature compensation value; and the corrected detection signal is processed to obtain the target signal; wherein the temperature compensation value is the temperature difference between the ambient temperature of the environment where the air conditioner 200 is located and the refrigerant temperature in the refrigerant pipe.
[0090] In this embodiment, the ambient temperature is detected by a temperature sensor built into the data processor 103. In other embodiments, the ambient temperature may also be detected by a temperature detection module located in the environment of the air conditioner 200, which is independent of the monitoring device 100.
[0091] In this embodiment, the temperature difference between the ambient temperature and the refrigerant temperature is a preset temperature difference obtained based on the ambient temperature. The temperature difference value is different depending on the ambient temperature, so the temperature difference value can be determined by detecting the ambient temperature alone.
[0092] In one implementation, the temperature difference value can be determined as the temperature compensation value. In another implementation, the temperature compensation value can be obtained by correcting the temperature difference value according to a correction coefficient.
[0093] The signal correction parameter may include a correction coefficient or a correction amplitude. When the signal correction parameter is a correction coefficient, the product of the detection signal of probe 102 and the correction coefficient can be used as the corrected detection signal; when the signal correction parameter is a correction amplitude, the sum of the detection signal of probe 102 and the correction amplitude can be used as the corrected detection signal.
[0094] In this embodiment, before processing the corrected detection signal to obtain the target signal, the signal correction parameter is determined based on the temperature compensation value and the coefficient corresponding to the material of the refrigerant pipe. Different materials correspond to different coefficients. For example, the detection signal of probe 102 can be corrected based on the following relationship: Z_corrected = Z_measured ×(1 + αΔT), where Z_corrected is the corrected detection signal, Z_measured is the initial detection signal of probe 102, (1 + αΔT) is the signal correction parameter, ΔT is the temperature difference value, and α is the coefficient corresponding to the material of the refrigerant pipe, for example, α=0.0035 / ℃ when the material is copper.
[0095] The corrected detection signal can be processed into the standard electrical signal described above.
[0096] In this embodiment, the detection signal of the target probe in the data acquisition component is corrected according to the signal correction parameter corresponding to the temperature compensation value, and the corrected detection signal is processed into the target signal corresponding to the target probe. The detection signals of other probes 102 in the data acquisition component besides the target probe do not need to be corrected; their detection signals are directly processed into the corresponding target signals. In this embodiment, the target probe includes a probe 102 equipped with a temperature sensor. Further, the target probe may also include a probe 102 equipped with a preset sensor and / or a probe 102 equipped with a detection electrode. Here, the preset sensor is not a temperature sensor, but its detection signal is affected by temperature factors.
[0097] During the test, when the air conditioner 200 is running with preset operating parameters, the heat exchanger 250 is in an evaporation or condensation state. The fan drives the air in the environment where the air conditioner 200 is located to exchange heat with the heat exchanger 250. The temperature that affects the corrosion of the refrigerant pipe is the combined temperature of the ambient temperature of the environment where the air conditioner 200 is located and the refrigerant temperature in the heat exchanger 250. Since there is a certain temperature difference between the ambient temperature and the refrigerant temperature, and the surface of the refrigerant pipe is provided with fins, the temperature at the location of the probe 102 will deviate from the actual temperature affecting the corrosion performance of the refrigerant pipe. Therefore, the detection signal of the probe 102 is corrected based on the temperature compensation value to ensure that the corrected detection signal can better match the actual corrosion state of the refrigerant pipe, thereby further improving the accuracy of the corrosion process state analysis of the air conditioning components.
[0098] By combining the temperature compensation value with the coefficient corresponding to the material of the refrigerant pipe to correct the detection signal of probe 102, the accuracy of temperature compensation can be improved, thereby further improving the accuracy of the corrosion process state analysis of air conditioning components.
[0099] In one feasible implementation, the data processor 103 is provided with fasteners for fixing the data processor 103 to the body of the component under test.
[0100] Fasteners may include at least one of the following: screws, clips, etc.
[0101] In this embodiment, the data processor 103 can be fixed to the top of the air conditioner 200 body with fasteners.
[0102] In this embodiment, fixing the data processor 103 to the air conditioner 200 with fasteners helps to improve the stability of signal transmission between the probe 102 and the data processor 103, thereby further improving the accuracy and reliability of monitoring the corrosion process of the component under test.
[0103] In one feasible implementation, combined with Figures 10 to 11 The data processor 103 is provided with at least two terminals, and the data acquisition component includes at least two probes 102, which are connected to the terminals one-to-one via connecting lines 300.
[0104] Based on this, the detection signals of different probes 102 can be transmitted independently through different channels, which helps to reduce interference between different detection signals and further improves the accuracy of corrosion process analysis of the component under test.
[0105] In other embodiments, the data processor 103 may also be provided with a terminal block that can be connected to different probes 102 simultaneously.
[0106] Combination Figures 2 to 9 This application also proposes a clamp 101 for use in the monitoring device 100 described above. The clamp 101 includes a mounting frame 10, which is provided with a mounting slot 11 for mounting the probe 102.
[0107] The mounting bracket 10 serves as the overall support structure for the clamp 101, and structures such as the probe 102 are fixedly or detachably mounted on the mounting bracket 10. Optionally, the mounting bracket 10 can be a plate-shaped, frame-shaped, column-shaped, or other shapes. Furthermore, the mounting bracket 10 can be fixed to the environment where the air conditioner 200 is located using methods such as snap-fit, screw connection, or threaded connection.
[0108] The mounting slot 11 on the mounting bracket 10 can penetrate through the first side 14 and the second side 15 of the mounting bracket 10, which are opposite to each other; alternatively, the mounting slot 11 can only penetrate through the first side 14 of the mounting bracket 10, without penetrating the second side 15. The shape of the mounting slot 11 can be, but is not limited to, circular, square, hexagonal, triangular, or other geometric shapes, which can be adjusted according to the shape of the probe 102. The size of the mounting slot 11 is 1mm to 2mm larger than the outer diameter of the probe 102.
[0109] The number of mounting slots 11 can be one or more. The number of mounting slots 11 is greater than or equal to the number of probes 102 in the data acquisition assembly. One mounting slot 11 is used to mount one probe 30.
[0110] In this embodiment, there is more than one mounting slot 11, and the more than one mounting slot 11 are distributed at intervals along the second preset direction on the mounting frame 10.
[0111] It should be noted that the probe 102 does not have an installation structure and cannot be directly installed in the operating environment of the component under test.
[0112] In this embodiment, the probe 102 can be mounted on the fixture 101 via the mounting slot 11 on the mounting bracket 10. The fixture 101 is then used to mount the probe 102 in the environment where the air conditioner is located, so that the probe 102 can be mounted in the operating environment of the component under test, and the probe 102 can cooperate with the data processor 103 to realize online monitoring of the corrosion status of the component under test.
[0113] In one embodiment, combined with Figure 4 , Figure 6 , Figure 8 as well as Figure 9 The mounting bracket 10 is also provided with a fixing member 70, which is used to fix the clamp 101 to the environment where the air conditioner 200 is located.
[0114] The fastener 70 can be one of the following: a fixing claw, a fixing buckle, a screw connector, etc.
[0115] In practical applications, the number of fixing members 70 can be one, two, or more. Furthermore, the shape and size of the fixing member 70 can be adjusted according to the shape and size of the heat exchange tube or other components it mates with. In some embodiments, the fixing member 70 can be selected when the heat exchange tube needs to be inserted into the fixing probe 102; the selection range is heat exchange tubes or other components with a diameter of 5mm or 7mm and a center distance of 14.5mm to 21.0mm.
[0116] In this embodiment, the fixing member 70 is used to fix the clamp 101 to the heat exchanger 250 in the air conditioner. In one implementation, the air conditioner 100 includes a heat exchanger 250, which includes at least two heat exchange tubes. Each heat exchange tube may include a tube segment as mentioned in the above embodiment and fins on the surface of the tube segment. The fixing member 70 includes fixing claws, which include at least two engaging portions. The engaging portions are configured to engage with the heat exchange tubes, wherein each engaging portion engages one heat exchange tube. Based on this, when the component under test is the heat exchanger 250 or a component in the environment where the heat exchanger 250 is located, the probe 102 can be quickly installed in the operating environment of the component under test using the fixing member 70 on the clamp 101, improving the convenience and reliability of probe 102 installation.
[0117] In practical applications, the data acquisition component includes at least two probes 102. The mounting bracket 10 is provided with at least two spaced mounting slots 11, and the at least two mounting slots 11 are arranged sequentially along a second preset direction. The component under test includes the refrigerant pipe of the heat exchanger 250. When at least two probes 102 are mounted on the mounting slots 11 of the mounting bracket 10 and the mounting bracket 10 is fixed to the heat exchanger 250 by the fasteners 70, the at least two probes 102 are arranged sequentially along the extension direction of each pipe segment in the refrigerant pipe. This allows the detection signals of the at least two probes 102 to accurately characterize the corrosion state of the corresponding pipe segment in the refrigerant pipe of the heat exchanger 250. In other embodiments, when at least two probes 102 are mounted on the mounting slots 11 of the mounting bracket 10 and the mounting bracket 10 is fixed to the heat exchanger 250 by the fasteners 70, the arrangement direction of the at least two probes 102 can also be set at an angle (e.g., perpendicular) to the extension direction of each pipe segment in the refrigerant pipe.
[0118] In this embodiment, the installation stability of the probe 102 can be effectively improved by setting the fastener 70, thereby improving the stability and reliability of the detection signal of the probe 102 and further enhancing the accuracy of corrosion monitoring of the component under test.
[0119] In one embodiment, combined with Figures 2 to 6 as well as Figures 8 to 9 The mounting bracket 10 is provided with at least two spaced mounting slots 11, and the mounting bracket 10 is provided with at least two fixing members 70. Each fixing member 70 is provided with a different mounting slot 11, and the number of mounting slots 11 is greater than or equal to the number of fixing members 70.
[0120] In one implementation, fasteners 70 are respectively provided at positions corresponding to at least two consecutive mounting slots 11 on one end of the mounting bracket 10 (e.g., the top or bottom end). In another implementation, fasteners 70 are respectively provided on the mounting bracket 10 at positions corresponding to each mounting slot 11. In yet another implementation, fasteners 70 are respectively provided on the mounting bracket 10 at positions corresponding to any two mounting slots 11 that meet preset conditions. The preset conditions include a preset number of spaced mounting slots 11 (e.g., 1 or 2, etc.). For example, if the preset number is 2, then a fastener 70 is provided every two mounting slots 11.
[0121] In practical applications, the mounting bracket 10 has 5 mounting slots 11, which are arranged sequentially along the second preset direction. The mounting bracket 10 has a fixing member 70 at the corresponding positions of the two mounting slots 11 arranged in order 4 and order 5. When the number of probes 102 required for corrosion detection of the component under test is 4, the mounting bracket 10 can be cut, retaining the four mounting slots 11 arranged in order 1 to 4 and the corresponding fixing members 70 for installing 4 probes 102. The mounting slot 11 arranged in order 5 and the corresponding fixing member 70 can be considered as redundant structures and discarded or used for other air conditioning. When the number of probes 102 required for corrosion detection of the component under test is 5, the mounting bracket 10 does not need to be cut, and all 5 mounting slots 11 and the two corresponding fixing members 70 are retained for installing 5 probes 102.
[0122] In this embodiment, by setting the fixing member 70 as described above, the number of probes 102 installed in the operating environment of the component under test can be set according to actual testing needs. The mounting bracket 10 can be adapted to the actual number of probes 102 required, so that the number of mounting slots 11 retained on the mounting bracket 100 is as close as possible to or equal to the required number of probes 102. The retained mounting slots 11 can be fixed to the operating environment of the component under test by the fixing member 70 retained together. Based on this, the assembly adaptability of the fixture 101 is effectively improved to meet the testing needs of different types of air conditioners or different components under test.
[0123] In one embodiment of this application, combined with Figures 2 to 9 The clamp 101 also includes a flow guide 20 disposed on one side of the mounting bracket 10. When the probe 102 is installed in the operating environment by the clamp 101, the flow guide 20 is located below the mounting slot 11. The flow guide 20 is provided with a flow guide groove 21, and a communicating space is formed between the flow guide groove 21 and the mounting slot 11.
[0124] The mounting bracket 10 is provided with at least two spaced mounting slots 11, and the mounting slots 11 are provided in a one-to-one correspondence with the guide member 20.
[0125] The flow guide 20, via the flow guide groove 21, is used to collect and discharge impurities such as condensate or corrosion products. Optionally, the flow guide 20 can be a plate-shaped, block-shaped, column-shaped, or other shape, as long as the flow guide groove 21 can be formed on the flow guide 20. Furthermore, the shape of the flow guide groove 21 formed on the flow guide 20 can be a rectangular groove, an arc-shaped groove, a strip-shaped groove, or some other shape of groove.
[0126] In this embodiment, the component under test includes the refrigerant pipe of the heat exchanger 250. During the operation of the air conditioner 200 with preset operating parameters, ambient air enters the air duct 230 and is blown towards the probe 102 and the heat exchanger 250 under the drive of the fan corresponding to the heat exchanger 250. When the airflow passes through the probe 102, it can blow off impurities such as condensate or corrosion products on the surface of the probe 102. The blown-off impurities are collected and discharged through the guide groove 21 below, thereby improving the measurement accuracy of the probe 102. In other implementations, without the drive of a fan, the condensate or impurities on the surface of the probe 102 can also fall into the guide groove 21 due to gravity.
[0127] In this embodiment, the flow guide 20 can effectively improve the detection accuracy of the probe 102, thereby further enhancing the accuracy of corrosion process state analysis of the component under test.
[0128] In one embodiment, combined with Figures 2 to 4 as well as Figures 6 to 8 The mounting bracket 10 has a first side 12 and a second side 13 opposite each other in the width direction. The guide channel 21 has a first water outlet 21a and a second water outlet 21b. The first water outlet 21a is flush with or protrudes from the first side 12, and the second water outlet 21b is flush with or protrudes from the second side 13.
[0129] In this embodiment, by designing the guide channel 21 with a first water outlet 21a and a second water outlet 21b, the condensate or corrosion products and other impurities on the surface of the probe 102 fall into the guide channel 21 under the action of airflow and can be diverted to the first water outlet 21a and the second water outlet 21b, so as to be discharged outward from the first water outlet 21a and the second water outlet 21b, thereby improving the impurity removal efficiency of the guide channel 21.
[0130] In this embodiment, by aligning the first water outlet 21a with or protruding from the first side 12 of the mounting bracket 10, and aligning the second water outlet 21b with or protruding from the second side 13 of the mounting bracket 10, the condensate or corrosion products discharged from the first water outlet 21a will not flow to the lower probe 102 when the mounting bracket 10 is equipped with at least two probes 102. Similarly, the condensate or corrosion products discharged from the second water outlet 21b will also not flow to the lower probe 102, thus preventing contamination of the lower probe 102 and affecting its measurement performance and accuracy.
[0131] Furthermore, since the first water outlet 21a of the guide channel 21 protrudes from the first side 12 of the mounting bracket 10, and the second water outlet 21b of the guide channel 21 protrudes from the second side 13 of the mounting bracket 10, the first water outlet 21a and the second water outlet 21b of the guide channel 21 are prone to interference with other air conditioning components of the air conditioner 200. Therefore, in this embodiment, the first water outlet 21a of the guide channel 21 is flush with the first side 12 of the mounting bracket 10, and the second water outlet 21b of the guide channel 21 is flush with the second side 13 of the mounting bracket 10.
[0132] In one embodiment, combined with Figures 8 to 9 The mounting bracket 10 has a first side 14. When the probe 102 is installed in the mounting slot 11, the first end of the probe 102 protrudes from the first side 14. The guide 20 is provided on the first side 14. When the probe 102 is installed in the mounting slot 11, the height of the first end of the probe 102 protruding from the first side 14 is defined as L1, and the width of the guide groove 21 in the facing direction of the first side 14 is L2. Then, L2>L1 is satisfied.
[0133] It should be noted that the mounting bracket 10 also has a second side 15 disposed opposite to the first side 14. The facing direction of the first side 14 refers to the direction that is perpendicular to the first side 14 and away from the second side 15.
[0134] In this embodiment, by making the width L2 of the guide groove 21 in the facing direction of the first side 14 greater than the height L1 of the probe 102 protruding from the first side 14, the condensate or corrosion products and other impurities falling from the surface of the probe 102 can fall fully into the guide groove 21 below, thus preventing the condensate or corrosion products and other impurities falling from the surface of the probe 102 from falling outside the guide groove 21 and causing contamination to the probe 102 or other components below.
[0135] Furthermore, L2 and L1 also satisfy: 1mm≤L2-L1≤2mm.
[0136] For example, the range of L2-L1 can specifically be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc.
[0137] When the width L2 of the guide channel 21 in the facing direction of the first side 14 is significantly smaller than the height L1 of the first end of the probe 102 protruding from the first side 14, some impurities such as condensate or corrosion products falling from the surface of the probe 102 will splash outside the guide channel 21, contaminating the probe 102 or other components below. Conversely, when the width L2 of the guide channel 21 in the facing direction of the first side 14 is significantly larger than the height L1 of the first end of the probe 102 protruding from the first side 14, the guide channel 21 is prone to interference with other air conditioning components of the air conditioner 200. Therefore, this embodiment, by making the width L2 of the guide channel 21 in the facing direction of the first side 14 1mm to 2mm larger than the height L1 of the first end of the probe 102 protruding from the first side 14, can prevent impurities from splashing outside the guide channel 21 and avoid interference between the guide channel 21 and other air conditioning components of the air conditioner 200.
[0138] In one embodiment, combined with Figure 2 and Figure 3 The guide channel 21 includes two interconnected water outlet sections 211. The two water outlet sections 211 are distributed along the width direction of the mounting frame 10. When the probe 102 is installed in the operating environment by the clamp 101, the ends of the two water outlet sections 211 that are far apart from each other are inclined downward.
[0139] In this embodiment, by setting the ends of the two water outlet sections 211 that are far apart from each other downwards, the condensate or corrosion products and other impurities on the surface of the probe 102 fall into the guide channel 21 under the action of airflow and can be diverted to the two water outlet sections 211. Then, under the action of gravity, the impurities flow to the ends of the two water outlet sections 211 that are far apart from each other, which is conducive to the removal of condensate and corrosion products and other impurities, and at the same time can improve the efficiency of the guide channel 21 in removing impurities.
[0140] In one embodiment of this application, the angle between the water outlet section 211 and the horizontal plane is defined as α, which satisfies: α≥45°.
[0141] Since when the angle α between the water outlet section 211 and the horizontal plane is too small, some impurities such as condensate and corrosion products are easily retained in the guide channel 21, this embodiment makes the angle α between the water outlet section 211 and the horizontal plane greater than or equal to 45°, so that impurities such as condensate and corrosion products can be smoothly discharged from the guide channel 21, which is more conducive to the removal of impurities such as condensate and corrosion products, and can further improve the efficiency of the guide channel 21 in removing impurities.
[0142] As some examples, the angle α between the water outlet section 211 and the horizontal plane can be 45°, 46°, 47°, 48°, 49°, 50°, 52°, 55°, 57°, 60°, 65°, 70°, 75°, 80°, 85°, etc.
[0143] In one embodiment of this application, combined with Figures 2 to 9 The mounting slot 11 passes through the first side 14 and the second side 15 opposite to each other on the mounting bracket 10. When the probe 102 is installed in the mounting slot 11, the first end of the probe 102 protrudes relative to the first side 14 and / or the second end of the probe 102 protrudes relative to the second side 15. The mounting bracket 10 is provided with a limiting structure, which is used to limit the protruding end of the probe 102 relative to the mounting bracket 10.
[0144] In this embodiment, the probe 102 includes a detection end and a connection end electrically connected to the detection end. The detection end is exposed at the first end of the probe 102, and the connection end is electrically connected to the data processor 103 via a connection line.
[0145] The limiting structure may include one or more limiting components. When the limiting structure includes more than one limiting component, different limiting components limit the end of the probe 102 protruding relative to the mounting bracket 10.
[0146] The limiting structure may include at least one of the following: a limiting baffle, a limiting buckle, a limiting sleeve, etc.
[0147] When the mounting bracket 10 is provided with at least two mounting slots 11, the mounting bracket 10 can be provided with at least two limiting structures. The limiting structures are provided in a one-to-one correspondence with the mounting slots 11. The probes 102 installed in each mounting slot 11 are equivalent to the protruding ends of the mounting bracket 10 being limited by the corresponding limiting structures.
[0148] When the probe 102 is installed in the mounting slot 11, the direction in which the first end of the probe 102 and the second end of the probe 102 extend is a third preset direction. The limiting structure is used to limit the position of the first end of the probe 102 and / or the second end of the probe 102 in the third preset direction and / or in the direction perpendicular to the third preset direction.
[0149] In this embodiment, the protruding end of the probe 102 is limited by a limiting structure, which helps to effectively improve the reliability of the probe 102 installation.
[0150] In one embodiment, combined with Figures 2 to 4 as well as Figures 6 to 9 The mounting bracket 10 is provided with a connecting part, and a first direction is defined as the direction from the position where the connecting part is connected to the mounting bracket 10 to the mounting slot 11. A baffle extending along the first direction is provided on the side of the connecting part away from the mounting bracket 10, and the baffle is used to limit the first end of the probe 102.
[0151] The first direction is set at an angle to the third preset direction, and the baffle can be used to limit the position of the probe 102 in the third preset direction.
[0152] The baffle and the connecting part can be integrally formed, or the baffle can be connected to the connecting part by means of adhesive, screw connection, snap-fit, etc. Furthermore, the baffle can be a straight plate, an arc plate, a bent plate, or some other shape baffle structure.
[0153] In practical applications, the baffle can abut against the end face of the first end of the probe 102, or it can have a gap between it and the end face of the first end of the probe 102.
[0154] The number of baffles can be one or more. In one implementation, the mounting bracket 10 is provided with more than one connecting part, and each connecting part has a baffle extending along a corresponding first direction on the side away from the mounting bracket 10. The first directions corresponding to different connecting parts are different. The more than one connecting part can be arranged opposite to each other or spaced around the edge of the mounting slot 11 on the mounting bracket 10.
[0155] In one embodiment, the probe 102 has a detection end exposed at a first end of the probe 102. The length of the baffle extending along the first direction is H, and the radius of the probe 102 is R, satisfying H < 1 / 2R. As some examples, the relationship between the length H of the baffle extending along the first direction and the radius R of the probe 102 can be H1 = 1 / 3R, H1 = 1 / 4R, H1 = 1 / 5R, H1 = 1 / 6R, H1 = 1 / 7R, H1 = 1 / 8R, H1 = 1 / 9R, H1 = 1 / 10R, H1 = 1 / 11R, H1 = 1 / 12R, etc.
[0156] In one embodiment, combined with Figures 2 to 4 , Figures 6 to 8The mounting bracket 10 is provided with at least two connecting parts and at least two corresponding baffles. The at least two connecting parts include a first connecting part 41 and a second connecting part 42. The at least two baffles include a first baffle 31 and a second baffle 32. The first baffle 31 is provided on the side of the first connecting part 41 away from the mounting bracket 10, and the second baffle 32 is provided on the side of the second connecting part 42 away from the mounting bracket 10. The first baffle 31 and the second baffle 32 are opposite to each other and spaced apart. The first direction corresponding to the first baffle 31 is the same as the direction from the first baffle 31 to the second baffle 32. The first direction corresponding to the second baffle 32 is the same as the direction from the second baffle 32 to the first baffle 31. The length of the first baffle 31 extending toward the second baffle 32 is defined as H1, and the radius of the probe 102 is R. Then, H1 < 1 / 2R. The length of the second baffle 32 extending toward the first baffle 31 is defined as H2, and the radius of the probe 102 is R. Then, H2 < 1 / 2R. The first baffle 31 and the second baffle 32 are spaced apart to form clearance openings for the connection ends of the corresponding probes 102. In some embodiments, the mounting bracket 10 may also be provided with a first connecting portion 41 and a second connecting portion 42, correspondingly provided with one of the first baffle 31 and the second baffle 32.
[0157] In some embodiments, combined with Figures 2 to 4 , Figure 6 as well as Figure 8 The first connecting part 41 is the aforementioned guide member 20, and the guide channel 21 has an upwardly extending first baffle 31 on the side away from the mounting bracket 10. In order to allow condensate and corrosion products falling from the surface of the probe 102 to fall smoothly into the guide channel 21, a gap may be optionally provided between the first baffle 31 and the end face of the probe 102. In addition to limiting the probe 102, the first baffle 31 can also prevent condensate and corrosion products from splashing outside the guide channel 21 during the process of falling into the guide channel 21.
[0158] In some embodiments, combined with Figure 2 and Figure 4 as well as Figure 7 The second baffle 32 and the second connecting part 42 are arranged at an angle. One side of the second connecting part 42 is connected to the mounting bracket 10 and is used to abut and limit the top of the probe 102. One side of the second baffle 32 is connected to the side of the second connecting part 42 away from the mounting bracket 10 and extends downward. The second baffle 32 is used to abut and limit the end face of the first end of the probe 102. The inner side of the connection position between the second baffle 32 and the second connecting part 42 is rounded and has reinforcing ribs.
[0159] In this embodiment, the baffle can limit the end face of the probe 102, improving the reliability of the probe 102 installation. The extension length H of the baffle is limited to less than half the radius R of the probe 102, which helps prevent the baffle from being too long and obstructing the detection end of the probe 102, effectively ensuring the detection accuracy of the probe 102 and further improving the accuracy of corrosion detection of the component under test.
[0160] In one embodiment, combined with Figure 2 as well as Figures 4 to 8 The limiting structure includes a limiting buckle 50, which is used to hold the second end of the probe 102.
[0161] In this embodiment, the mounting slot 11 passes through the first side 14 and the second side 15 opposite to the mounting bracket 10. When the probe 102 is installed in the mounting slot 11, the first end of the probe 102 protrudes relative to the first side 14 and the second end of the probe 102 protrudes relative to the second side 15. The second side 15 is provided with a limiting buckle 50, which is used to hold the end of the probe 102 that protrudes from the second side 15.
[0162] The aforementioned guide element 20 is located on the first side 14.
[0163] In practical applications, one limit buckle 50 can be used to hold the probe 102, or two or more limit buckles 50 can be used to hold the probe 102.
[0164] With this configuration, when installing the probe 102, the first end of the probe 102 can be inserted into the mounting slot 11 from the side of the mounting slot 11 near the second side 15, passing over the limiting buckle 50. Then, the probe 102 is pushed towards the first side 14 from the second end of the probe 102, so that the first end of the probe 102 gradually protrudes towards the first side 14 of the mounting bracket 10, until the second end of the probe 102 protruding from the second side 15 engages with the limiting buckle 50 on the second side 15. The limiting buckle 50 can then fix and limit the second end of the probe 102, thereby further improving the installation reliability of the probe 102.
[0165] In some embodiments, to improve the holding and limiting effect of the probe 102, a pair of limiting buckles 50 can be used to hold and cooperate with the probe 102. The pair of limiting buckles 50 are respectively provided on opposite sides of the mounting slot 11. Since the probe 102 cannot be inserted between the two limiting buckles 50 when the distance between them is too small, and the two limiting buckles 50 will lose their limiting effect on the probe 102 when the distance between them is too large, this embodiment allows the distance between the pair of limiting buckles 50 to be 1mm to 1.5mm smaller than the outer diameter of the probe 102. This effectively prevents the probe 102 from being unable to be inserted between the two limiting buckles 50, and also prevents the limiting buckles 50 from losing their limiting effect on the probe 102. Specifically, the distance between the pair of limiting buckles 50 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc., smaller than the outer diameter of the probe 102.
[0166] In one embodiment, combined with Figure 2 , Figures 4 to 9 The limiting structure includes a limiting sleeve 60, which surrounds the mounting slot 11. When the probe 102 is installed in the mounting slot 11, the second end of the probe 102 passes through the limiting sleeve 60.
[0167] In this embodiment, the limiting sleeve 60 is provided on the second side 15 of the mounting bracket 10.
[0168] In practical applications, the cross-sectional shape of the limiting sleeve 60 can be, but is not limited to, circular, square, hexagonal, triangular and other geometric shapes, which can be adjusted according to the shape of the probe 102.
[0169] With this configuration, when installing the probe 102, one end of the probe 102 can be passed over the limiting buckle 50 from the side of the mounting slot 11 near the second side 15, then passed through the limiting sleeve 60 and inserted into the mounting slot 11. Then, the probe 102 can be pushed backward from the end of the probe 102 near the second side 15, so that one end of the probe 102 gradually protrudes towards the first side 14 of the mounting bracket 10, until the end of the probe 102 protruding from the second side 15 engages with the limiting buckle 50 on the second side 15. Thus, the installation reliability of the probe 102 can be further improved by the combined limiting effect of the limiting sleeve 60 and the limiting buckle 50.
[0170] In one embodiment of this application, combined with Figure 2 , Figure 7 as well as Figure 8 The mounting bracket 10 is also provided with a wire clamping groove 80, which is used to hold the connecting wire 300 between the probe 102 and the data processor 103.
[0171] In some embodiments, in order to facilitate the insertion of the connecting wire 300 into the wire clamping groove 80, the clamping distance of the wire clamping groove 80 can be 1mm to 1.5mm smaller than the total outer diameter of the wire harness formed by all the connecting wires 300 tightly arranged between the probe 102 and the data processor 103. Specifically, it can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc.
[0172] In this embodiment, by setting a wire clamping groove 80 on the mounting bracket 10, the connecting wire 300 is held in place by the wire clamping groove 80, thereby improving the overall wiring of the monitoring device 100.
[0173] Combination Figures 10 to 11 This application also proposes an air conditioning testing system 1000, which includes an air conditioner 200 and the aforementioned monitoring device 100. The monitoring device 100 may include the aforementioned fixture 101, and the probe 102 is mounted on the fixture 101. The fixture 101 is mounted on the air conditioner 200 and the probe 102 is located in the operating environment of the component under test.
[0174] The specific structure of the monitoring device 100 is as described in the above embodiments. Since the air conditioning test system 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0175] In practical applications, the data processor 103 can be installed inside or outside the air conditioner 200. In some embodiments, when the data processor 103 is installed outside the air conditioner 200, a protective housing 400 can be provided to protect the data processor 103 from rain, dust, and other impurities in the external environment, thereby extending the service life of the data processor 103.
[0176] In this embodiment, the clamp 101 can be installed on the component under test inside the air conditioner 200, or on other components outside the component under test in the operating environment of the component under test inside the air conditioner 200, or it can be installed outside the air conditioner 200 with the portion equipped with the probe 102 extending into the operating environment of the component under test.
[0177] During the test, while the air conditioner 200 operates with preset operating parameters, the data processor 103 can acquire the detection signals from the probe 102 in real time, process the detection signals into target signals, and send the target signals to the analysis device 500 in real time. The analysis device 500 can record the received target signals and determine the corrosion status information of the component under test in the operating environment based on the recorded target signals. The preset operating parameters are the air conditioner operating parameters set according to the air conditioner operating conditions corresponding to the corrosion testing requirements of the component under test. Among them, the analysis device 500 can analyze the changing patterns of the received target signals, and the corrosion status information of the component under test in different time periods within the operating cycle of the air conditioner 200, based on the changing patterns of the target signals corresponding to each probe, can include corrosion behavior information.
[0178] In one embodiment, the component to be tested includes a refrigerant pipe of a heat exchanger 250, and the detection end of the probe 102 is positioned toward the air inlet direction of the heat exchanger 250.
[0179] In this embodiment, based on the above settings, during the operation of the air conditioner 200, the ambient air driven by the fan enters the air duct 230 of the air conditioner 200 and can be blown simultaneously onto the refrigerant pipe and the detection end. Based on this, it can be avoided that the detection end is blocked, which would prevent corrosion-related factors in the environment from directly affecting the detection end. This is conducive to the detection signal of the detection end being more consistent with the actual corrosion situation of the refrigerant pipe, and further improves the accuracy of the analysis of the corrosion state of the refrigerant pipe.
[0180] In one feasible implementation, combining Figure 10 The clamp 101 is installed on the heat exchanger 250, which is located in the outdoor unit of the air conditioner 200. The detection end of the probe 102 is positioned facing the air inlet 210 of the outdoor unit. Here, the air conditioner 200 is a split-type air conditioner, which includes an indoor unit and an outdoor unit. The heat exchanger 250 in the outdoor unit is generally located in the outdoor air duct 230 near the air inlet 210. Driven by a fan, air enters the outdoor air duct 230 from the air inlet 210 and blows towards the heat exchanger 250. The clamp 101 and the probe 102 can be located on the windward or leeward side of the heat exchanger 250. Based on this, the detection end of the probe 102 is set towards the air inlet 210, and the air that causes corrosion to the refrigerant pipe of the heat exchanger 250 is blown towards the heat exchanger 250 in the same direction as the air blown towards the detection end, thereby further improving the accuracy of the detection signal of the detection end in characterizing the corrosion of the refrigerant pipe of the heat exchanger 250 in the outdoor unit.
[0181] In another feasible implementation, combining Figure 11The air conditioner 200 is a window air conditioner. The heat exchanger 250 is located in the outdoor air duct 230 of the window air conditioner. The clamp 101 is installed on the leeward side of the heat exchanger 250 and is located outside the window air conditioner. The detection end of the probe 102 is positioned facing the air outlet 220 of the outdoor air duct 230. Driven by a fan, airflow blows from the first side of the heat exchanger 250 to the second side of the heat exchanger 250, where the leeward side refers to the second side. In a window air conditioner, the heat exchanger 250 is generally located at the end of the outdoor air duct 230 near the air outlet 220. In this embodiment, the clamp 101 and the probe 102 mounted on it are both located outside the window air conditioner. In addition to the heat exchanger 250, the outdoor air duct 230 of the window air conditioner is equipped with a water pumping motor. Moisture generated during the pumping process, driven by the fan in the outdoor air duct 230, flows through the heat exchanger 250 and is blown out of the window air conditioner through the air outlet 220. At this time, the detection end of the probe 102 is positioned facing the air outlet 220, ensuring that the direction in which the ambient air and moisture are blown towards the heat exchanger 250 is the same as the direction towards the detection end. This ensures that the detection signal at the detection end can accurately characterize the corrosive effect of the ambient air and moisture generated by the pumping motor on the refrigerant pipes of the heat exchanger 250, effectively improving the accuracy of refrigerant pipe corrosion analysis in the window air conditioner. Furthermore, the fixture 101 is installed outside the window air conditioner, which allows corrosion detection to be completed without disassembling the heat exchanger 250 during the test.
[0182] In other embodiments, the clamp 101 in the window air conditioner may also be installed on the windward side of the heat exchanger 250.
[0183] In one embodiment, combined with Figure 10 and Figure 11 The data processor 103 is installed outside the body of the air conditioner 200 where the component to be tested is located. The probe 102 is installed inside the body through the clamp 101. The body is provided with a wire outlet hole 240. The probe 102 and the data processor 103 are electrically connected through a connecting wire 300, which passes through the wire outlet hole 240.
[0184] The unit here can be the outdoor unit or the main body of a window air conditioner. When the unit is an outdoor unit, a cable outlet hole 240 can be provided on the top cover of the unit near the air inlet 210; when the unit is the main body of a window air conditioner, a cable outlet hole 240 can be provided on the back of the unit where the air outlet 220 is located.
[0185] In this embodiment, the through-hole 240 ensures that the corrosion status of the component under test can be monitored online, while the data processor 103 can be installed without occupying the internal space of the air conditioner 200. This reduces the impact of corrosion monitoring on the internal structure of the air conditioner 200, ensures that the operating environment of the component under test during the test is as close as possible to the actual operating environment of the component under test in the product, ensures the accuracy of corrosion detection of the component under test, and improves the effectiveness of the anti-corrosion scheme formulated based on the corrosion analysis results.
[0186] In the testing scenarios for the outdoor unit of a split-type air conditioner, such as Figure 10 As shown, the number of probes 102 can be up to 4. The probes 102 are installed on the clamp 101, and the top of the clamp 101 is fixed to the left side panel of the outdoor unit of the air conditioner 200 with screws. The bottom of the clamp 101 is fastened to the heat exchange tube of the heat exchanger 250 with a fixing buckle. The data processor 103 is fixed to the left side of the top cover of the outdoor unit with screws. At the same time, a wire outlet hole 240 is opened on the left side of the top cover of the outdoor unit for the probe 102 to be connected to the data processor 103. The data processor 103 is equipped with a protective shell 400 to prevent rain. During the operation of the air conditioner 200, the probes 102 detect synchronously, and the detected detection signals are collected by the data processor 103 and uploaded to the analysis device 500.
[0187] In the testing scenario for window air conditioners, such as Figure 11 As shown, the number of probes 102 can be up to 5. The probes 102 are installed in the clamp 101, and the top and bottom of the clamp 101 are fastened into the heat exchange tube in the lower area of the heat exchanger 250 with fixing buckles. The data processor 103 is fixed to the right side of the top cover of the window air conditioner with screws. At the same time, a wire outlet hole 240 is opened on the back of the outdoor unit for the probe 102 to be connected to the data processor 103. During the operation of the air conditioner 200, the probes 102 detect synchronously, and the detected detection signal is collected by the data processor 103 and uploaded to the analysis device 500.

Any equivalent structural transformations made based on the technical concept of this application and the content of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
