[0002] With the development of air conditioning technology and the continuous improvement of people's living standards, air conditioning systems have been widely used to ensure user experience. Currently, for air conditioning piping in air conditioning systems, vibration stress testing and evaluation of the piping system are usually carried out during the design and development stage to reduce the risk of piping breakage during the application of the air conditioning system.

[0003] However, in actual use of air conditioning systems, factors such as transportation, installation, and aging and deformation of vibration damping materials can all cause piping to deform under stress. This can lead to strong vibrations during use, resulting in pipe breaks. Currently, there is no effective safety inspection and protection system for the piping, making it difficult to detect pipe breaks in a timely manner. This can damage the air conditioning compressor and severely affect the operating efficiency of the air conditioning system.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] An embodiment of this application provides a method for protecting air conditioning piping, referring to... Figure 1 As shown, the method is applied to air conditioning equipment, and the method includes the following steps:

[0033] Step 101: Obtain the ambient temperature parameters of the environment where the air conditioning equipment is located, the current operating frequency of the compressor, and the current vibration parameters of the air conditioning piping.

[0034] In this embodiment, the ambient temperature parameter of the environment where the air conditioning equipment is located can be obtained by a temperature detection device installed on the air conditioning equipment, or by a temperature detection device that has a communication connection with the air conditioning equipment and is located in the same environment as the air conditioning equipment sending the detected ambient temperature parameter to the air conditioning equipment. The current operating frequency of the compressor included in the air conditioning equipment can be determined from the control unit corresponding to the air conditioning equipment. The current vibration parameter of the air conditioning piping can be obtained by a vibration detection device installed on the outdoor unit of the air conditioning equipment to detect the vibration of the outdoor unit, or by a vibration detection device to detect the vibration of the air conditioning piping inside the outdoor unit.

[0035] Step 102: Determine the preset vibration parameters based on the ambient temperature parameters and the current operating frequency.

[0036] In this embodiment, the air conditioning equipment stores preset relationships obtained from numerous experiments. These preset relationships correspond to the vibration parameters of the air conditioning piping under different usage stages, ambient temperature parameters, and compressor operating frequencies, assuming normal vibration. These preset relationships can be expressed using calculation formulas or in a list format, depending on the specific circumstances. Thus, after determining the ambient temperature parameters and the current operating frequency, the corresponding preset vibration parameters can be obtained through these relationships.

[0037] Step 103: Based on the current vibration parameters and preset vibration parameters, determine the protection operation for the air conditioning piping.

[0038] In this embodiment of the application, the current vibration parameters and preset vibration parameters are analyzed to determine the protection operation for the air conditioning piping, wherein the protection operation for the air conditioning piping is the operation to reduce the vibration of the air conditioning piping.

[0039] Step 104: Perform protection operations for the air conditioning piping.

[0040] In this embodiment of the application, after determining the protection operation for the air conditioning piping, the protection operation for the air conditioning piping is executed to reduce the vibration of the air conditioning piping and avoid the air conditioning piping from breaking due to excessive vibration.

[0041] In this embodiment, after obtaining the ambient temperature parameters of the current environment where the air conditioning equipment is located, the current operating frequency of the compressor, and the current vibration parameters of the air conditioning piping, preset vibration parameters are determined based on the ambient temperature parameters and the current power frequency. Based on the current vibration parameters and the preset vibration parameters, protection operations for the air conditioning piping are determined and finally executed. In this way, after determining the corresponding preset vibration parameters based on the ambient temperature parameters of the air conditioning equipment's environment and the current operating frequency of the compressor, the protection operations to be performed on the air conditioning piping are determined based on the preset vibration parameters and the current vibration parameters of the air conditioning piping. This solves the problem of the lack of an effective technical solution for the safety detection of air conditioning piping, and proposes a technical solution for the safety detection of air conditioning piping, enabling timely detection of pipe breakage faults, reducing the possibility of compressor damage due to pipe breakage, and ensuring the working efficiency of the air conditioning system.

[0042] Based on the foregoing embodiments, embodiments of this application provide an air conditioning piping protection method, referring to... Figure 2 As shown, the method is applied to air conditioning equipment, and the method includes the following steps:

[0043] Step 201: Obtain the ambient temperature parameters of the environment where the air conditioning equipment is located, the current operating frequency of the compressor, and the current vibration parameters of the air conditioning piping.

[0044] Among them, the ambient temperature parameters include at least the indoor ambient temperature parameters where the air conditioning equipment is located and the outdoor ambient temperature parameters where the air conditioning equipment is located.

[0045] In this embodiment, the indoor ambient temperature parameter of the air conditioning equipment can be detected by a temperature detection device installed on the indoor unit of the air conditioning equipment, and the outdoor ambient temperature parameter of the air conditioning equipment can be detected by a temperature detection device installed on the outdoor unit.

[0046] Step 202: Determine the preset vibration parameters based on the ambient temperature parameters and the current operating frequency.

[0047] In this embodiment, the air conditioning equipment uses a pre-set preset relationship to analyze the indoor ambient temperature parameters, outdoor ambient temperature parameters, and current operating frequency to determine the preset vibration parameters.

[0048] Step 203: Determine the first difference between the current vibration parameters and the preset vibration parameters.

[0049] In this embodiment of the application, the first difference can be calculated using the formula "first difference = current vibration parameter - preset vibration parameter".

[0050] Step 204: If the first difference is greater than or equal to the preset vibration threshold, determine the frequency reduction amplitude for the compressor.

[0051] Among these, protective operations include reducing the operating frequency of the compressor.

[0052] In this embodiment, the preset vibration threshold is a vibration intensity threshold obtained from numerous experiments. When the first difference is greater than or equal to the preset vibration threshold, it indicates that the current vibration amplitude of the air conditioning piping is large, which may cause irreversible damage to the air conditioning piping, such as pipe breakage. Therefore, when the first difference is greater than or equal to the preset vibration threshold, the frequency reduction amplitude for the compressor is determined. The compressor frequency reduction amplitude can be a pre-set empirical value, or different empirical values ​​set for different vibration conditions, which can be determined according to the actual situation.

[0053] Step 205: Perform protection operations for the air conditioning piping.

[0054] In this embodiment of the application, after determining the frequency reduction amplitude for the compressor, the operating frequency of the air conditioning equipment compressor is reduced by the frequency reduction amplitude to achieve the protection operation of the air conditioning piping.

[0055] Based on the foregoing embodiments, in other embodiments of this application, step 205 can be implemented by steps 205a to 205b:

[0056] Step 205a: Determine the difference between the current operating frequency and the frequency reduction amplitude to obtain the target operating frequency of the compressor.

[0057] In this embodiment of the application, the target operating frequency of the compressor can be calculated using the formula "target operating frequency of the compressor = current operating frequency - frequency reduction amplitude".

[0058] Step 205b: Adjust the compressor's operating frequency to the target operating frequency.

[0059] In this embodiment, the compressor is subjected to a forced frequency reduction operation, which forcibly reduces the operating frequency of the compressor to the target operating frequency.

[0060] Based on the foregoing embodiments, in other embodiments of this application, refer to... Figure 3 As shown, after the air conditioning equipment performs step 205, it is also used to perform steps 206 to 211:

[0061] Step 206: After the preset duration of the protection operation, execute the step "obtain the ambient temperature parameters of the environment where the air conditioning equipment is located, the current operating frequency of the compressor and the current vibration parameters of the air conditioning piping" until the first difference is less than the preset vibration threshold, and then obtain the operating parameters of the air conditioning equipment at this time.

[0062] In this embodiment, the preset duration can be an empirical value obtained from numerous experiments, or it can be a preset duration corresponding to the frequency reduction amplitude. This is used to ensure the compressor operates at the target frequency for the preset duration before subsequent analysis is performed, guaranteeing the stability of the compressor after frequency reduction. After the compressor reduces its frequency to the target operating frequency for the preset duration, steps 201-205 are repeated until the corresponding first difference is detected to be less than a preset vibration threshold. At this point, the operating conditions of the air conditioning equipment are obtained, i.e., the operating parameters of the air conditioning equipment. These operating parameters include at least one of the following: the current indoor ambient temperature parameter, the user-preset desired ambient temperature parameter, and the operating mode of the air conditioning equipment.

[0063] Step 207: Determine the recommended operating frequency of the compressor based on the operating parameters.

[0064] In this embodiment, the air conditioning device analyzes operating parameters to determine the recommended operating frequency of the compressor. For example, when the operating parameters include the current indoor ambient temperature, the user-preset desired ambient temperature, and the operating mode of the air conditioning device, the recommended operating frequency of the compressor when the indoor ambient temperature is adjusted to the desired ambient temperature in the operating mode can be determined. It should be noted that the compressor of the air conditioning device operates at the target operating frequency continuously at this time; the operating frequency of the air conditioning device is not adjusted from the target operating frequency to the recommended operating frequency.

[0065] Step 208: Determine the fault status of the air conditioning piping based on the recommended operating frequency and the target operating frequency.

[0066] The target operating frequency is the operating frequency of the compressor when it performs a protection operation.

[0067] In this embodiment of the application, the recommended operating frequency and target operating frequency of the compressor are analyzed to determine the fault status of the air conditioning piping.

[0068] Step 209: If the fault status is the first status, control the air conditioning equipment to stop working.

[0069] In this embodiment, the first state indicates an abnormality in the air conditioning piping. When the fault state is the first state, in order to ensure the safe use of the air conditioning equipment and reduce the impact on the safety of other components of the air conditioning equipment, the air conditioning equipment must be stopped immediately.

[0070] Step 210: Generate a prompt message to indicate that there is an abnormality in the air conditioning piping.

[0071] In this embodiment of the application, after the air conditioning equipment stops working, a prompt message indicating that there is an abnormality in the air conditioning piping is also required. On the one hand, this informs the user that the air conditioning equipment has stopped working due to a malfunction, and on the other hand, it informs the user of the specific location of the malfunction so that the user can quickly locate the malfunction and carry out corresponding repairs, thereby improving the user experience.

[0072] Step 211: Display a prompt message.

[0073] In this embodiment, the generated prompt information can be a combination of one or more forms such as sound, text, images, and light. When displaying the prompt information, it can be shown on the corresponding display screen of the air conditioning device, on a smart home central controller that has a communication connection with the air conditioning device, or on a smart mobile terminal that has a communication connection with the air conditioning device. It can also be a combination of the above display methods, which can be determined according to the actual situation and is not specifically limited here.

[0074] Based on the foregoing embodiments, in other embodiments of this application, step 208 can be implemented by steps 208a to 208b, or steps 208a and 208c:

[0075] Step 208a: Determine the third difference between the recommended operating frequency and the target operating frequency.

[0076] In this embodiment of the application, the third difference can be calculated by the formula "third difference = recommended operating frequency - target operating frequency".

[0077] Step 208b: If the third difference is greater than or equal to the preset frequency threshold, determine the fault state as the first state.

[0078] In this embodiment, the preset frequency threshold can be an empirical value obtained from a large number of experiments. When the third difference is greater than or equal to the preset frequency threshold, the fault state of the air conditioning piping is determined as the first state.

[0079] Step 208c: If the third difference is less than the preset frequency threshold, determine the fault state as the second state.

[0080] In this embodiment, the second state indicates that the air conditioning piping is normal. When the third difference is less than a preset frequency threshold, the fault state of the air conditioning piping is determined to be the second state.

[0081] Based on the foregoing embodiments, in other embodiments of this application, reference is made to... Figure 4 As shown, after the air conditioning unit performs step 208, it can also choose to perform step 212:

[0082] Step 212: If the fault state is the second state, control the compressor to continue working at the target operating frequency and execute the step "obtain the ambient temperature parameters of the environment where the air conditioning equipment is located, the current operating frequency of the compressor and the current vibration parameters of the air conditioning piping".

[0083] In this embodiment of the application, when the fault state is the second state, it indicates that there is no abnormality in the air conditioning piping. The air conditioning equipment repeats steps 201 to 212 to realize the abnormal monitoring and protection operation of the air conditioning piping.

[0084] Based on the foregoing embodiments, in other embodiments of this application, reference is made to... Figure 5 As shown, before the air conditioning equipment performs step 201, it also performs step 213:

[0085] Step 213: Collect the current vibration parameters of the air conditioning piping using a vibration detection device.

[0086] The vibration detection device is installed in close contact with the compressor receiver inside the outdoor unit of the air conditioning equipment.

[0087] In this embodiment, the vibration detection device can be a vibration sensor or a piezoelectric sensor. The corresponding current vibration parameters can be represented by vibration amplitude, voltage signal value, or current signal value, etc. The specific type of the current vibration parameter can be determined by the actual vibration detection device used. Due to the eccentric operation of the compressor, the compressor vibration is transmitted to the entire piping system through copper pipe connections. The vibration of the air conditioning piping appears to be greatest in the circumferential direction of the compressor receiver, which is far from the center line. Therefore, by detecting the vibration on the compressor receiver, the vibration of the air conditioning piping can be accurately indicated. Thus, the vibration of the compressor receiver can be selected as the vibration of the air conditioning piping.

[0088] Based on the foregoing embodiments, this application provides a method for protecting air conditioning piping, which is applied to, for example... Figure 6 The air conditioning unit with the shown connection structure includes a four-way valve A, an indoor evaporator (including a fan) B, an electronic expansion valve C, an outdoor condenser (including a fan) D, a compressor E, a compressor receiver F, and a vibration detection device G. The vibration detection device G is mounted on the compressor receiver F and can be implemented using a piezoelectric sensor. Correspondingly, the structure of the vibration detection device G mounted on the compressor receiver F includes: Figure 7 The image shows clamps, such as... Figure 8The diagram shows a piezoelectric sensor support plate including a support plate groove H, and a piezoelectric sensor. During installation, a vibration transmission device is constructed using clamps. A rubber band is placed in the middle of the clamps, which are then secured to the upper end of the compressor receiver with screws. The clamps also have a protruding surface designed to fit tightly against the piezoelectric sensor. The other side of the piezoelectric sensor is positioned within the piezoelectric sensor support plate groove H. The piezoelectric sensor support plate can be fixed to a compressor bracket adjacent to the compressor receiver with screws. This bracket can be designed as a bracket groove to ensure the piezoelectric sensor fits tightly against the protruding surface of the vibration transmission device, guaranteeing accurate detection of vibration information from the air conditioning piping. The implementation process of the corresponding air conditioning piping protection method can be referred to [reference needed]. Figure 9 As shown, it includes the following steps:

[0089] Step 301: During the development and design phase of the air conditioning system, after the air conditioning piping design is finalized, test the voltage parameter values ​​of the piezoelectric sensor installed on the compressor receiver of the air conditioning system under different ambient temperatures and different operating frequencies of the compressor.

[0090] Step 302: Based on the voltage parameter values ​​corresponding to different ambient temperatures and different operating frequencies, determine the corresponding logical relationships throughout the entire operating life cycle of the air conditioning system.

[0091] Step 303: Obtain the real-time ambient temperature T1, the current operating frequency F1 of the compressor, and the voltage parameter value V21 detected in real time by the piezoelectric sensor when the air conditioning equipment is currently operating.

[0092] Step 304: Determine the preset voltage parameter value V11 based on the real-time ambient temperature T1, the current operating frequency F1, and the logic relationship.

[0093] The preset voltage parameter value is the theoretically permissible vibration condition of the air conditioning piping corresponding to the real-time ambient temperature T1 and the current operating frequency F1.

[0094] Step 305: Determine whether V21-V11 is greater than or equal to the revised voltage ΔV1. If not, proceed to step 306; otherwise, proceed to step 307.

[0095] Step 306: The air conditioning equipment is operating normally.

[0096] Step 307: Force the compressor to reduce its frequency by an amplitude of ΔHz1. After a preset time interval of ΔT1, obtain the real-time ambient temperature T2, the compressor's current operating frequency F2, and the voltage parameter value V22 detected in real time by the piezoelectric sensor.

[0097] Step 308: Determine the preset voltage parameter value V12 based on the real-time ambient temperature T2, the current operating frequency F2, and the logic relationship.

[0098] Step 309: Determine whether V22-V12 is greater than or equal to the revised voltage ΔV2. If not, proceed to step 310; otherwise, proceed to step 307.

[0099] Step 310: Obtain the compressor's operating frequency Hz1, and simultaneously obtain the compressor's preset operating frequency Hz2 corresponding to the current operating parameters of the air conditioning equipment.

[0100] Step 311: Determine whether Hz2-Hz1 is greater than the revised frequency ΔHz2. If yes, proceed to step 312; otherwise, proceed to step 303.

[0101] Step 312: The air conditioning equipment stops operating and displays a message indicating abnormal vibration of the air conditioning piping.

[0102] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.
