Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to a control method, device and parking air conditioner for a parking air conditioner. Background Technology

[0002] Most vehicles are equipped with air conditioners. During vehicle operation, the vehicle itself will vibrate. When the vibration frequency of the vehicle and the vibration frequency of the air conditioner are the same, resonance will occur. Prolonged resonance may lead to problems such as loose air conditioner components and pipe leaks.

[0003] Currently, before air conditioners leave the factory, noise and vibration tests are conducted at compressor frequency points, and those frequencies that fail to meet the standards are disabled. This method can assess the operating status of a single air conditioner, but it cannot determine the operating status of the air conditioner when installed in different vehicles or when the vehicle is traveling under different road conditions. There is still a significant possibility of resonance, which can affect the reliability of the air conditioner. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a control method, device, and parking air conditioner, which can effectively limit the resonance phenomenon of the parking air conditioner when installed in different vehicles or when vehicles are traveling under different road conditions, thereby improving the operational reliability of the parking air conditioner.

[0005] In a first aspect, this application provides a control method for a parking air conditioner, the parking air conditioner comprising:

[0006] compressor;

[0007] An amplitude sensor is used to collect the vibration amplitude of the parking air conditioner.

[0008] A controller, which is connected to the compressor and the amplitude sensor;

[0009] The method includes:

[0010] When the compressor is operating at a first target frequency, the amplitude sensor acquires the first vibration amplitude of the parking air conditioner. The first target frequency is one of a plurality of target operating frequencies in a set of target frequencies. The target operating frequency is located within the operating frequency range of the compressor. The number of frequencies in the set of target frequencies is less than the number of frequencies in the operating frequency range.

[0011] When the first vibration amplitude is greater than or equal to the target amplitude threshold, the controller adjusts the operating frequency of the compressor, and obtains the second vibration amplitude of the parking air conditioner after the compressor adjusts its operating frequency.

[0012] The controller determines the second target frequency of the compressor based on the second vibration amplitude and the target amplitude threshold, and controls the compressor to operate at the second target frequency.

[0013] According to the control method of the parking air conditioner of this application, by obtaining the first vibration amplitude corresponding to the compressor operating at the first target frequency, monitoring the vibration state of the parking air conditioner, adjusting the operating frequency of the compressor in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor is controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon of the parking air conditioner when it is installed in different vehicles or when the vehicle is driving under different road conditions, and improve the operational reliability of the parking air conditioner.

[0014] According to one embodiment of this application, the controller adjusts the operating frequency of the compressor, including:

[0015] The controller determines the frequency adjustment amount corresponding to the first vibration amplitude;

[0016] The controller adjusts the operating frequency of the compressor according to the frequency adjustment amount.

[0017] The above technical solution has at least the following technical effects: based on the first vibration amplitude corresponding to the current operation of the compressor, the corresponding frequency adjustment amount is calculated, and the operating frequency is adjusted according to the frequency adjustment amount based on the first target frequency, so as to optimize the operating frequency more quickly and accurately.

[0018] According to one embodiment of this application, the controller determines a second target frequency of the compressor based on the second vibration amplitude and the target amplitude threshold, including:

[0019] The controller compares the second vibration amplitude with the target amplitude threshold, and determines whether to continue adjusting the operating frequency of the compressor based on the comparison result;

[0020] If it is determined that the operating frequency of the compressor should be adjusted, the controller adjusts the operating frequency of the compressor, and each adjustment of the operating frequency corresponds to the acquisition of a second vibration amplitude;

[0021] If it is determined that the operating frequency of the compressor should be stopped, the controller determines the second target frequency.

[0022] The above technical solution has at least the following technical effects: accurately adjusting the operating frequency of the compressor based on the feedback of the second vibration amplitude can effectively limit the resonance phenomenon when the vehicle is driving on complex road conditions or when the parking air conditioner is installed in different vehicles.

[0023] According to one embodiment of this application, when it is determined that the adjustment of the compressor's operating frequency should be stopped, the controller determines the second target frequency, including:

[0024] If the second vibration amplitude corresponding to the current operating frequency of the compressor is less than the target amplitude threshold, the controller determines to stop adjusting the operating frequency of the compressor and uses the current operating frequency of the compressor as the second target frequency.

[0025] The above technical solution has at least the following technical effects: when the second vibration amplitude corresponding to the current operating frequency of the compressor is less than the target amplitude threshold, it can effectively limit the resonance between the parking air conditioner and the vehicle, and the vibration of the parking air conditioner will not cause damage to parts, connecting pipes, etc.

[0026] According to one embodiment of this application, when it is determined that the adjustment of the compressor's operating frequency should be stopped, the controller determines the second target frequency, including:

[0027] When the compressor adjusts its frequency within the operating frequency range and all of the second vibration amplitudes are greater than or equal to the target amplitude threshold, the controller takes the operating frequency corresponding to the minimum value among the multiple second vibration amplitudes as the second target frequency.

[0028] The above technical solution has at least the following technical effects: the minimum amplitude is determined from multiple second vibration amplitudes, and the operating frequency corresponding to the minimum value is used as the second target frequency, so as to reduce the amplitude of the parking air conditioner when the compressor is running, reduce abnormal vibration noise, and reduce the risk of damage and rupture of gas pipeline.

[0029] According to one embodiment of this application, the target operating frequency is determined based on the load demand of the parking air conditioner.

[0030] The above technical solution has at least the following technical effects: the target operating frequency meets the load requirements of the parking air conditioner, providing the vehicle with a temperature and humidity environment that meets the requirements.

[0031] According to one embodiment of this application, the difference between two adjacent target operating frequencies in the target frequency set is equal.

[0032] The above technical solution has at least the following technical effects: the difference between two adjacent target operating frequencies in the target frequency set is equal, which ensures that when the first vibration amplitude corresponding to the first target frequency is greater than or equal to the target amplitude threshold, the adjustment range of the compressor operating frequency is guaranteed.

[0033] According to one embodiment of this application, during the process of adjusting the operating frequency of the compressor, the controller has a higher priority in adjusting the operating frequency of the compressor by decreasing it than in adjusting the operating frequency of the compressor by increasing it.

[0034] The above technical solution has at least the following technical effects: following the frequency regulation principle of first reducing and then increasing, when it is necessary to adjust the operating frequency of the compressor, the operating frequency is reduced first based on the current operating frequency of the compressor, which can limit the compressor frequency from being too high and reduce the risk of compressor system overshoot.

[0035] According to one embodiment of this application, after the amplitude sensor acquires the first vibration amplitude of the parking air conditioner, the method further includes:

[0036] If the first vibration amplitude is less than the target amplitude threshold, the controller maintains the compressor's current operating frequency.

[0037] The above technical solution has at least the following technical effects: the first vibration amplitude being less than the target amplitude threshold indicates that there is no resonance between the parking air conditioner and the vehicle, the compressor maintains the first target frequency, and the vibration of the parking air conditioner will not cause damage to parts, connecting pipes, etc.

[0038] Secondly, this application provides a control device for a parking air conditioner, the parking air conditioner comprising:

[0039] compressor;

[0040] An amplitude sensor is used to collect the vibration amplitude of the parking air conditioner.

[0041] The control device is connected to the compressor and the amplitude sensor, and the control device includes:

[0042] The first processing module is used to obtain the first vibration amplitude of the parking air conditioner through the amplitude sensor when the compressor is running at the first target frequency. The first target frequency is one of a plurality of target operating frequencies in a set of target frequencies. The target operating frequency is located within the operating frequency range of the compressor. The number of frequencies in the set of target frequencies is less than the number of frequencies in the operating frequency range.

[0043] The second processing module is used to adjust the operating frequency of the compressor when the first vibration amplitude is greater than or equal to the target amplitude threshold, and to obtain the second vibration amplitude of the parking air conditioner after the compressor adjusts its operating frequency.

[0044] The third processing module is used to determine the second target frequency of the compressor based on the second vibration amplitude and the target amplitude threshold, and to control the compressor to operate at the second target frequency.

[0045] According to the control device of the parking air conditioner of this application, by acquiring the first vibration amplitude corresponding to the compressor operating at the first target frequency, monitoring the vibration state of the parking air conditioner, adjusting the operating frequency of the compressor in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor is controlled to operate at the second target frequency, which can effectively limit the resonance phenomenon of the parking air conditioner when it is installed in different vehicles or when the vehicle is driving under different road conditions, and improve the operational reliability of the parking air conditioner.

[0046] Thirdly, this application provides a parking air conditioner, the parking air conditioner comprising:

[0047] compressor;

[0048] An amplitude sensor is used to collect the vibration amplitude of the parking air conditioner.

[0049] The control device for the parking air conditioner as described in the second aspect above is connected to the compressor and the amplitude sensor.

[0069] Parking air conditioner 800, compressor 810, amplitude sensor 820, body 900. Detailed Implementation

[0070] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0071] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0072] The following description, in conjunction with the accompanying drawings, details the control method for the parking air conditioner 800, the control device 700 for the parking air conditioner 800, the parking air conditioner 800, the vehicle, the electronic equipment, and the readable storage medium provided in this application, through specific embodiments and application scenarios.

[0073] The control method for the parking air conditioner 800 can be applied to the parking air conditioner 800, and can be executed by the hardware or software in the parking air conditioner 800.

[0074] The parking air conditioner 800 is an air conditioner used in vehicles. The vehicle's DC power supply powers the parking air conditioner 800, which regulates and controls parameters such as temperature, humidity, and airflow of the air inside the vehicle.

[0075] In practice, the parking air conditioner 800 can be used in vehicles such as transport trucks, RVs, and buses to provide a comfortable environment for the driver's cab.

[0076] The parking air conditioner 800 may include components such as a compressor 810, a controller, an amplitude sensor 820, a heat exchanger, and a throttling element.

[0077] The compressor 810, outdoor heat exchanger, throttling element and indoor heat exchanger are connected in sequence to form a refrigerant circuit. The controller is connected to the compressor 810. The controller can control the refrigerant to circulate in the refrigerant circuit to realize the cooling or heating function of the parking air conditioner 800.

[0078] The compressor 810 compresses the refrigerant and drives its circulation. The compressor 810 vibrates significantly during operation and is the main source of vibration for the parking air conditioner 800. The frequency of the compressor 810 may be equal to the frequency of the vehicle, resulting in resonance.

[0079] The amplitude sensor 820 is used to collect the vibration amplitude of the parking air conditioner 800 and monitor the vibration state of the parking air conditioner 800 when the compressor 810 is running.

[0080] Understandably, after the compressor 810 starts running, the compressor 810 is the main source of vibration in the parking air conditioner 800. An amplitude sensor 820 can be installed on or near the compressor 810 to monitor the vibration state of the parking air conditioner 800, determine whether the parking air conditioner 800 resonates with the vehicle, and determine whether there is a risk of damage or breakage to the components and pipes in the parking air conditioner 800.

[0081] For example, an amplitude sensor 820 can be installed on the intake pipe or exhaust pipe that is close to the compressor 810 to collect vibration amplitude data of the parking air conditioner 800.

[0082] This application provides a control method for a parking air conditioner 800, which can effectively limit the resonance phenomenon of the parking air conditioner 800 when it is installed in different vehicles or when the vehicle is traveling on different road conditions, thereby improving the operational reliability of the parking air conditioner 800.

[0083] It should be noted that the parking air conditioner 800 is installed in the vehicle, and the control method of the parking air conditioner 800 is used for the parking air conditioner 800 that has been installed in the vehicle.

[0084] like Figure 1 As shown, the control method of the parking air conditioner 800 includes steps 110, 120 and 130.

[0085] Step 110: When the compressor 810 is running at the first target frequency, the amplitude sensor 820 acquires the first vibration amplitude of the parking air conditioner 800.

[0086] The first target frequency is one of the multiple target operating frequencies in the target frequency set. The target operating frequency is located within the operating frequency range of the compressor 810, and the number of frequencies in the target frequency set is less than the number of frequencies in the operating frequency range.

[0087] The target frequency set is a preset set of frequency points for the compressor 810 to operate. The target frequency set may include multiple target operating frequencies. When the parking air conditioner 800 is turned on, it can select one target operating frequency from the multiple target operating frequencies as the first target frequency and control the compressor 810 to operate according to the first target frequency.

[0088] For example, the target frequency set includes eight target operating frequencies: Fn1, Fn2, Fn3, Fn4, Fn5, Fn6, Fn7, and Fn8. When the parking air conditioner 800 is turned on, Fn4 is selected as the first target frequency, and the compressor 810 is controlled to operate according to Fn4.

[0089] It is understandable that the operating frequency range refers to the range of frequencies within which the compressor 810 is allowed to operate, and the operating frequency range can be determined based on the rated operating frequency of the compressor 810.

[0090] In this embodiment, the target operating frequency in the target frequency set is located within the operating frequency range of the compressor 810. The first target frequency is selected from the target frequency set to control the operation of the compressor 810, thereby limiting the compressor 810 to operate within the allowable operating range.

[0091] It should be noted that resonance is a phenomenon where vibrations amplify when two objects have the same or similar frequencies. Related technologies use fuzzy control to select frequency points within the operating frequency range of the air conditioner. Each frequency point within the operating frequency range may occur, and the probability that the air conditioner component has the same or similar frequency as the vehicle is relatively high. In this embodiment, the number of frequencies in the target frequency set is less than the number of frequencies in the operating frequency range. The compressor 810 operates according to the target operating frequency of the target frequency set, and the probability that the compressor 810 has the same or similar frequency as the vehicle is relatively low, which can reduce the probability of resonance between the parking air conditioner 800 and the vehicle.

[0092] For example, the operating frequency range is 20Hz-90Hz. Related technologies select 70 frequency points. The probability that the frequency is the same as the vehicle's operating frequency is 70 / number of vehicle operating frequencies. In this embodiment, the number of frequencies in the target frequency set is less than 70, and the probability that the frequency is the same as the vehicle's operating frequency is less than 70 / number of vehicle operating frequencies. This can effectively reduce the probability of the parking air conditioner 800 resonating with the vehicle.

[0093] In this step, when the compressor 810 is running at the first target frequency, the vibration amplitude data of the parking air conditioner 800, i.e. the first vibration amplitude, can be collected by the amplitude sensor 820 to monitor the vibration state of the parking air conditioner 800 when the compressor 810 is running.

[0094] Step 120: When the first vibration amplitude is greater than or equal to the target amplitude threshold, the controller adjusts the operating frequency of the compressor 810 and obtains the second vibration amplitude of the parking air conditioner 800 after the compressor 810 adjusts its operating frequency.

[0095] The target amplitude threshold is a preset critical value used to determine whether the parking air conditioner 800 resonates with the vehicle.

[0096] In this embodiment, when the first vibration amplitude is greater than or equal to the target amplitude threshold, the parking air conditioner 800 may resonate with the vehicle, and the components and connecting pipes in the parking air conditioner 800 may be damaged or broken. The target amplitude threshold also reflects the maximum displacement allowed by the vibration of the components and pipes on the parking air conditioner 800.

[0097] In this step, when the first vibration amplitude is greater than or equal to the target amplitude threshold, the operating frequency of the compressor 810 is adjusted to limit the resonance phenomenon between the parking air conditioner 800 and the vehicle, reduce the risk of damage or breakage of components and connecting pipes in the parking air conditioner 800, and obtain the second vibration amplitude after the operating frequency of the compressor 810 is adjusted.

[0098] Understandably, the second vibration amplitude can reflect whether there is still resonance (or risk of resonance) between the parking air conditioner 800 and the vehicle after the compressor 810 adjusts its operating frequency.

[0099] In this embodiment, the operating frequency of the compressor 810 is adjusted from the original first target frequency to a new operating frequency.

[0100] Step 130: Based on the second vibration amplitude and the target amplitude threshold, the controller determines the second target frequency of the compressor 810 and controls the compressor 810 to operate at the second target frequency.

[0101] Understandably, by comparing the second vibration amplitude obtained after the compressor 810 adjusts its operating frequency with the target amplitude threshold, it can be determined whether there is still resonance between the parking air conditioner 800 and the vehicle after the compressor 810 adjusts its operating frequency.

[0102] In this step, the second target frequency of the compressor 810 is determined based on the second vibration amplitude and the target amplitude threshold. The second target frequency is a different operating frequency from the first target frequency. Controlling the compressor 810 to operate at the second target frequency can limit the resonance between the parking air conditioner 800 and the vehicle, reduce the abnormal vibration noise of the parking air conditioner 800, and reduce the risk of damage or breakage of components and connecting pipes in the parking air conditioner 800.

[0103] It is understandable that when a vehicle is driving on a road with complex conditions, the vehicle's natural frequency changes with the road conditions. Since the natural frequency is a variable, the operating frequency of the compressor 810 may be consistent with the natural frequency of the vehicle, resulting in resonance and generating resonance noise. Long-term resonance operation may also lead to pipe cracks and leaks, affecting the operational reliability of the parking air conditioner 800. Similarly, it is impossible to effectively determine whether the parking air conditioner 800 will generate resonance when installed in different types of vehicles.

[0104] In related technologies, noise and vibration tests are conducted at frequency points before the air conditioner leaves the factory, and frequencies that fail to meet the standards are disabled. This method can assess the operating status of a single air conditioner, but it cannot determine the operating status of the air conditioner when it is installed in different vehicles or when the vehicle is traveling under different road conditions. There is still a high probability that resonance may occur, affecting the reliability of the air conditioner.

[0105] In this embodiment, the compressor 810 operates at a first target frequency selected from the target frequency set. The probability that the compressor 810 and the vehicle have the same or similar frequencies is small, which can reduce the probability of resonance between the parking air conditioner 800 and the vehicle. The first vibration amplitude is obtained, and the vibration state of the gas pipeline in the parking air conditioner 800 is monitored. When the first vibration amplitude is greater than or equal to the target amplitude threshold, the operating frequency of the compressor 810 is adjusted to limit the harm caused by resonance. Combined with the feedback of the second vibration amplitude, the second target frequency of the compressor 810 is optimized and controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon when the vehicle is driving on complex road conditions or when the parking air conditioner 800 is installed in different vehicles, reduce abnormal vibration noise, reduce the risk of damage and rupture of the gas pipeline, and improve the operational reliability of the parking air conditioner 800.

[0106] According to the control method of the parking air conditioner 800 provided in the embodiments of this application, by obtaining the first vibration amplitude corresponding to the compressor 810 operating at the first target frequency, monitoring the vibration state of the parking air conditioner 800, adjusting the operating frequency of the compressor 810 in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor 810 is controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon of the parking air conditioner 800 when it is installed in different vehicles or when the vehicle is driving under different road conditions, thereby improving the operational reliability of the parking air conditioner 800.

[0107] In some embodiments, adjusting the operating frequency of the compressor 810 by the controller may include:

[0108] The controller determines the frequency adjustment amount corresponding to the first vibration amplitude;

[0109] The controller adjusts the operating frequency of compressor 810 according to the frequency adjustment amount.

[0110] Among them, the frequency adjustment amount is the frequency change amount when the operating frequency of compressor 810 is adjusted once.

[0111] For example, if the frequency adjustment is 1Hz, the operating frequency of compressor 810 is adjusted once, either by increasing the first target frequency by 1Hz or decreasing the first target frequency by 1Hz.

[0112] In this embodiment, when it is determined that the operating frequency of the compressor 810 needs to be adjusted, the corresponding frequency adjustment amount is calculated according to the first vibration amplitude corresponding to the current operation of the compressor 810. Based on the first target frequency, the operating frequency is adjusted according to the frequency adjustment amount, so as to optimize the operating frequency more quickly and accurately.

[0113] In actual implementation, the corresponding frequency adjustment amount is determined based on the first vibration amplitude. The first vibration amplitude and the frequency adjustment amount can be positively correlated. The larger the first vibration amplitude, the larger the frequency adjustment amount for adjusting the operating frequency of the compressor 810.

[0114] For example, the compressor 810 operates at a first target frequency Fn, obtains a first vibration amplitude Δx, determines the amplitude range to which the first vibration amplitude Δx belongs, and determines the frequency adjustment amount ΔF based on the amplitude range.

[0115] When 350μm≤Δx<360μm, the frequency adjustment amount ΔF is 1Hz. The operating frequency of compressor 810 is adjusted according to Fn±1Hz, with each adjustment being 1Hz.

[0116] When 360μm≤Δx<370μm, the frequency adjustment amount ΔF is 2Hz. The operating frequency of compressor 810 is adjusted according to Fn±2Hz, with an adjustment of 2Hz each time.

[0117] When 370μm≤Δx<380μm, the frequency adjustment amount ΔF is 3Hz. The operating frequency of compressor 810 is adjusted according to Fn±3Hz, with an adjustment of 3Hz each time.

[0118] When 380μm≤Δx<390μm, the frequency adjustment amount ΔF is 4Hz. The operating frequency of compressor 810 is adjusted according to Fn±4Hz, with an adjustment of 4Hz each time.

[0119] When 390μm≤Δx<400μm, the frequency adjustment amount ΔF is 5Hz. The operating frequency of compressor 810 is adjusted according to Fn±4Hz, with each adjustment being 5Hz.

[0120] In this embodiment, when Δx≥400μm, it indicates that the compressor 810 is vibrating violently, and the compressor 810 can be controlled to stop running, reducing the risk of damage to components in the parking air conditioner 800.

[0121] In some embodiments, such as Figure 2 As shown, step 130, where the controller determines the second target frequency of the compressor 810 based on the second vibration amplitude and the target amplitude threshold, may include:

[0122] Step 131: The controller compares the second vibration amplitude with the target amplitude threshold and determines whether to continue adjusting the operating frequency of the compressor 810 based on the comparison result;

[0123] Step 132: If it is determined that the operating frequency of compressor 810 should continue to be adjusted, the controller adjusts the operating frequency of compressor 810, and each adjustment of the operating frequency of compressor 810 corresponds to the acquisition of a second vibration amplitude.

[0124] Step 133: After determining that the operating frequency of compressor 810 has been stopped, the controller determines the second target frequency.

[0125] Understandably, the second vibration amplitude is the pipe amplitude data obtained after the compressor 810 adjusts its operating frequency. By comparing the second vibration amplitude with the target amplitude threshold, it can be determined whether the compressor 810's adjustment of its operating frequency effectively limits the resonance phenomenon between the parking air conditioner 800 and the vehicle.

[0126] When resonance still exists between the parking air conditioner 800 and the vehicle or there is a risk of resonance, continue to adjust the operating frequency of the compressor 810. When there is no resonance between the parking air conditioner 800 and the vehicle or the risk of resonance is low, the adjustment of the operating frequency of the compressor 810 can be stopped to obtain the second target frequency for controlling the operation of the compressor 810. The operating frequency of the compressor 810 can be accurately adjusted according to the feedback of the second vibration amplitude, which can effectively limit the resonance phenomenon when the vehicle is driving on complex road conditions or when the parking air conditioner 800 is installed in different vehicles.

[0127] In this embodiment, each time the operating frequency of the compressor 810 is adjusted, a corresponding second vibration amplitude is obtained, and then the second vibration amplitude is compared with the target amplitude threshold to determine whether the operating frequency of the compressor 810 needs to be adjusted further.

[0128] It is understandable that the current adjustment of the operating frequency of compressor 810 is based on the operating frequency of compressor 810 in the previous stage.

[0129] For example, when the parking air conditioner 800 is turned on, the compressor 810 operates at the first target frequency Fn, and the first vibration amplitude is acquired in real time. When the first vibration amplitude is greater than or equal to the target amplitude threshold, the amplitude adjustment amount corresponding to the first vibration amplitude is determined to be 1Hz, the operating frequency of the compressor 810 is adjusted to Fn-1Hz, and the second vibration amplitude Δx1 is acquired.

[0130] When it is determined that the operating frequency needs to be adjusted further based on the second vibration amplitude Δx1 and the target amplitude threshold, the operating frequency of the compressor 810 is adjusted from Fn-1Hz to Fn-2Hz to obtain the second vibration amplitude Δx2.

[0131] When it is determined that the operating frequency needs to be adjusted further based on the second vibration amplitude Δx2 and the target amplitude threshold, the operating frequency of the compressor 810 is adjusted from Fn-2Hz to Fn-3Hz to obtain the second vibration amplitude Δx3, and so on.

[0132] In some embodiments, when it is determined that the operating frequency of the compressor 810 should be stopped, the controller determines a second target frequency, including:

[0133] If the second vibration amplitude corresponding to the current operating frequency of compressor 810 is less than the target amplitude threshold, the controller determines to stop adjusting the operating frequency of compressor 810 and takes the current operating frequency of compressor 810 as the second target frequency.

[0134] In this embodiment, after adjusting the operating frequency of the compressor 810, the second vibration amplitude corresponding to the current operating frequency of the compressor 810 is less than the target amplitude threshold. This indicates that when the compressor 810 operates at the current operating frequency, it can effectively limit the resonance between the parking air conditioner 800 and the vehicle. The current operating frequency of the compressor 810 can be used as the second target frequency, and the vibration of the parking air conditioner 800 will not cause damage to parts, connecting pipes, etc.

[0135] For example, such as Figure 3 As shown in step 132, if it is determined that the operating frequency of the compressor 810 should continue to be adjusted, the controller adjusts the operating frequency of the compressor 810, and each adjustment of the operating frequency of the compressor 810 corresponds to obtaining a second vibration amplitude.

[0136] When the second vibration amplitude is greater than or equal to the target amplitude threshold, it is determined that the operating frequency needs to be adjusted further. The operating frequency of the compressor 810 is adjusted from Fn1 to Fn2, and the second vibration amplitude corresponding to Fn2 is obtained.

[0137] Step 133A: When the second vibration amplitude corresponding to the current operating frequency of compressor 810 is less than the target amplitude threshold, the controller determines to stop adjusting the operating frequency of compressor 810 and takes the current operating frequency of compressor 810 as the second target frequency.

[0138] When the second vibration amplitude corresponding to Fn2 is less than the target amplitude threshold, it is determined that the adjustment of the operating frequency of the compressor 810 can be stopped, and the current operating frequency Fn2 of the compressor 810 is taken as the second target frequency.

[0139] In some embodiments, when it is determined that the operating frequency of the compressor 810 should be stopped, the controller determines a second target frequency, including:

[0140] When the compressor 810 adjusts its frequency within the operating frequency range and all of the multiple second vibration amplitudes are greater than or equal to the target amplitude threshold, the controller takes the operating frequency corresponding to the minimum value among the multiple second vibration amplitudes as the second target frequency.

[0141] It should be noted that the adjustment of the operating frequency of compressor 810 is carried out within the operating frequency range of compressor 810, and the adjusted operating frequency of compressor 810 will not exceed the operating frequency range.

[0142] In this embodiment, frequency adjustment is performed within the operating frequency range. When multiple second vibration amplitudes after the operating frequency of compressor 810 is adjusted are greater than or equal to the target amplitude threshold, the adjustment of the operating frequency of compressor 810 is stopped. The minimum amplitude value is determined from the multiple second vibration amplitudes, and the operating frequency corresponding to the minimum value is taken as the second target frequency. This reduces the amplitude of the parking air conditioner 800 when compressor 810 is running, reduces abnormal vibration noise, and lowers the risk of damage or rupture of gas pipelines.

[0143] For example, such as Figure 4 As shown in step 132, if it is determined that the operating frequency of the compressor 810 should continue to be adjusted, the controller adjusts the operating frequency of the compressor 810, and each adjustment of the operating frequency of the compressor 810 corresponds to obtaining a second vibration amplitude.

[0144] When the second vibration amplitude is greater than or equal to the target amplitude threshold, it is determined that the operating frequency needs to be adjusted. After adjusting the operating frequency of the compressor 810, the corresponding second vibration amplitude is obtained.

[0145] Step 133B: When the compressor 810 adjusts the frequency within the operating frequency range and all the second vibration amplitudes are greater than or equal to the target amplitude threshold, the controller takes the operating frequency corresponding to the minimum value among the multiple second vibration amplitudes as the second target frequency.

[0146] There are 10 frequency points in the operating frequency range, Fn1, Fn2...Fn10. When the second vibration amplitude of the compressor 810 at these 10 frequency points is greater than or equal to the target amplitude threshold, the adjustment of the operating frequency of the compressor 810 is stopped.

[0147] The minimum value among the 10 second vibration amplitudes is determined, and the frequency point corresponding to the minimum value is Fn2. Fn2 is taken as the second target frequency.

[0148] In some embodiments, the target operating frequency is determined based on the load demand of the parking air conditioner 800.

[0149] In this embodiment, a target operating frequency can be set within the operating frequency range of the compressor 810, taking into account the load demand of the parking air conditioner 800. Multiple target operating frequencies in the target frequency set correspond to different load demands. The target operating frequency meets the load demand of the parking air conditioner 810, providing the vehicle with a temperature and humidity environment that meets the requirements.

[0150] Among them, the load demand can be the heat removed or added to the room by the parking air conditioner 800 to maintain the indoor temperature (such as the driver's cab). The load demand can include both cooling load and heating load.

[0151] In practice, load demand can be determined based on the difference between the current indoor temperature and the set target temperature.

[0152] For example, the current indoor temperature is T room Set the target temperature as T set According to the temperature difference ΔT = T room -T set Once the load demand is obtained, the target operating frequency corresponding to the load demand is determined.

[0153] The relationship between the temperature difference ΔT and the target operating frequency Fn is shown in Table 1 below:

[0154] Table 1

[0155] <![CDATA[ΔT=T room -T set ]]> Fn ΔT≥13℃ Fn8 (90Hz) maximum frequency 13℃>ΔT≥11℃ Fn7 (80Hz) 11℃>ΔT≥9℃ Fn6 (70Hz) 9℃>ΔT≥7℃ Fn5 (60Hz) 7℃>ΔT≥5℃ Fn4 (50Hz) 5℃>ΔT≥3℃ Fn3 (40Hz) 3℃>ΔT≥1℃ Fn2 (30Hz) 1℃>ΔT≥0℃ Fn1 (20Hz) minimum frequency ΔT < 0℃ 0

[0156] The operating frequency range of compressor 810 is 20Hz-90Hz. When ΔT < 0℃, the operating frequency of compressor 810 can be 0, and compressor 810 will stop running.

[0157] In this embodiment, the parking air conditioner 800 is started, and the current load demand of the parking air conditioner 800 is determined based on the difference between the current indoor temperature and the set target temperature. Based on the current load demand, the corresponding target operating frequency is searched in the target frequency set as the first target frequency, and the compressor 810 is controlled to operate at the first target frequency.

[0158] Understandably, it is possible to monitor the difference between the current indoor temperature and the set target temperature in real time, update the current load demand, find the corresponding target operating frequency as the new first target frequency, and control the compressor 810 to operate at the new first target frequency.

[0159] In some embodiments, the difference between two adjacent target operating frequencies in the target frequency set is equal.

[0160] In this embodiment, within the operating frequency range of the compressor 810, multiple target operating frequencies can be evenly divided according to a preset frequency difference, with the difference between two adjacent target operating frequencies being equal.

[0161] For example, the operating frequency range of compressor 810 is 20Hz-90Hz, with a preset frequency difference of 10Hz, which is divided into Fn1 (20Hz), Fn2 (30Hz), Fn3 (40Hz), Fn4 (50Hz), Fn5 (60Hz), Fn6 (70Hz), Fn7 (80Hz), and Fn8 (90Hz).

[0162] In this embodiment, when determining the target operating frequency within the operating frequency range of the compressor 810 according to the rule that the difference between two adjacent target operating frequencies is equal, the setting can be combined with the load demand, so as to select the first target frequency according to different load demands.

[0163] It should be noted that the difference between two adjacent target operating frequencies in the target frequency set is equal, which ensures that when the first vibration amplitude corresponding to the first target frequency is greater than or equal to the target amplitude threshold, the adjustment range of the operating frequency of the compressor 810 is guaranteed.

[0164] Understandably, the number and values ​​of target operating frequencies in the target frequency set can be adjusted according to the actual application.

[0165] In actual implementation, the target frequency set can be stored in an EEPROM (Electrically Erasable Programmable Read Only Memory) storage chip. The data is not lost after power failure, which makes it easy to adjust the number and frequency value of the target operating frequencies in the target frequency set.

[0166] In some embodiments, during the adjustment of the operating frequency of the compressor 810, the controller has a higher priority in adjusting the operating frequency of the compressor 810 by decreasing it than in adjusting the operating frequency of the compressor 810 by increasing it.

[0167] In this embodiment, following the frequency adjustment principle of first decreasing and then increasing, when it is necessary to adjust the operating frequency of compressor 810, the operating frequency is reduced first based on the current operating frequency of compressor 810. This can limit the frequency of compressor 810 from being too high and reduce the risk of overshoot in compressor 810 system.

[0168] For example, if the frequency adjustment is 1Hz and the compressor 810 is operating at the first target frequency Fn, the priority of adjusting the operating frequency of the compressor 810 to a lower level is greater than the priority of adjusting the operating frequency of the compressor 810 to a higher level. Therefore, the operating frequency of the compressor 810 is adjusted to Fn-1Hz first.

[0169] In actual implementation, the operating frequency of compressor 810 can be adjusted by first reducing it within the operating frequency range of compressor 810. After adjusting to the minimum value of the operating frequency range, and judging from the corresponding second vibration amplitude, the operating frequency of compressor 810 can be adjusted by increasing it.

[0170] For example, the operating frequency range of compressor 810 is 20Hz-30Hz. The operating frequency of compressor 810 is 25Hz. The operating frequency of compressor 810 is adjusted first in the order of 24Hz, 23Hz, 22Hz, 21Hz, and 20Hz. If further adjustment is needed based on the corresponding second vibration amplitude, the operating frequency of compressor 810 is then adjusted in the order of 26Hz, 27Hz, 28Hz, 29Hz, and 30Hz.

[0171] In actual operation, during the frequency optimization adjustment of compressor 810, the pressure, temperature, current and other parameters of each component of parking air conditioner 800 are monitored in real time to ensure the safe operation of parking air conditioner 800.

[0172] In some embodiments, such as Figure 5 As shown, after step 110, where the amplitude sensor 820 acquires the first vibration amplitude of the parking air conditioner 800, the control method for the parking air conditioner 800 may further include:

[0173] Step 140: If the first vibration amplitude is less than the target amplitude threshold, the controller maintains the current operating frequency of the compressor 810.

[0174] In this embodiment, during the operation of the compressor 810 at the first target frequency, the first vibration amplitude is less than the target amplitude threshold, indicating that there is no resonance between the parking air conditioner 800 and the vehicle, and the vibration of the parking air conditioner 800 will not cause damage to parts, connecting pipes, etc. The compressor 810 maintains the current operating frequency (i.e. the first target frequency).

[0175] Taking a target amplitude threshold of 350μm as an example, when the first vibration amplitude is less than 350μm, the current operating frequency of the compressor 810 is maintained. When the first vibration amplitude is greater than or equal to 350μm, the operating frequency of the compressor 810 is adjusted. Each time the operating frequency is adjusted, a corresponding second vibration amplitude is obtained to determine the vibration state.

[0176] The following is a specific example.

[0177] like Figure 6 As shown, based on the operating frequency range of the compressor 810 and combined with the load requirements, eight target operating frequencies are evenly divided: Fn1 (20Hz), Fn2 (30Hz), Fn3 (40Hz), Fn4 (50Hz), Fn5 (60Hz), Fn6 (70Hz), Fn7 (80Hz), and Fn8 (90Hz), resulting in a target frequency set. The number of frequencies in the target frequency set is less than the number of frequencies in the operating frequency range, thus reducing the probability of resonance between the parking air conditioner 800 and the vehicle.

[0178] The parking air conditioner 800 starts, and the target compressor 810 operates at the first target frequency corresponding to the current load demand. The first target frequency is the target operating frequency selected from the target frequency set based on the current load demand.

[0179] The compressor 810 operates at the first target frequency, acquires the first vibration amplitude, and monitors the pipeline vibration status after the compressor 810 starts running.

[0180] When the first vibration amplitude is less than the target amplitude threshold, the compressor 810 maintains its current operating frequency.

[0181] When the first vibration amplitude is greater than or equal to the target amplitude threshold, the operating frequency of the compressor 810 is adjusted according to the frequency adjustment amount corresponding to the first vibration amplitude, and frequency optimization control is performed based on the current operating frequency.

[0182] Within the operating frequency range, the compressor 810 adjusts the operating frequency once and obtains a second vibration amplitude. It then determines whether the second vibration amplitude is less than the target amplitude threshold during the adjustment process.

[0183] When the second vibration amplitude is less than the target amplitude threshold, the operating frequency adjustment of the compressor 810 is stopped, and the compressor 810 operates at the operating frequency corresponding to the second vibration amplitude which is less than the target amplitude threshold.

[0184] The second vibration amplitudes within the operating frequency range are all greater than or equal to the target amplitude threshold. That is, during the adjustment process, the second vibration amplitudes are all greater than or equal to the target amplitude threshold. The compressor 810 operates at the operating frequency corresponding to the minimum value among these second vibration amplitudes.

[0185] In this embodiment, the compressor 810 operates at a first target frequency selected from the target frequency set, reducing the probability of resonance between the parking air conditioner 800 and the vehicle. It monitors the vibration state of the gas pipeline in the parking air conditioner 800 in real time. If resonance is possible, frequency optimization control is performed based on the current operating frequency. The vibration state of the gas pipeline is monitored, and a second target frequency for the compressor 810 is obtained through optimization. Controlling the compressor 810 to operate at the second target frequency effectively limits resonance when the vehicle is traveling on complex road conditions or when the parking air conditioner 800 is installed in different vehicles, reduces abnormal vibration noise, lowers the risk of gas pipeline damage or rupture, and improves the operational reliability of the parking air conditioner 800.

[0186] The control method for the parking air conditioner 800 provided in this application embodiment can be executed by the control device 700 of the parking air conditioner 800. This application embodiment uses the control device 700 of the parking air conditioner 800 executing the control method as an example to illustrate the control device 700 of the parking air conditioner 800 provided in this application embodiment.

[0187] This application embodiment also provides a control device 700 for a parking air conditioner 800. The parking air conditioner 800 is installed in a vehicle and includes a compressor 810 and an amplitude sensor 820. The control device 700 is connected to the compressor 810 and the amplitude sensor 820.

[0188] The compressor 810 compresses the refrigerant and drives its circulation. The compressor 810 vibrates significantly during operation and is the main source of vibration for the parking air conditioner 800. The frequency of the compressor 810 may be equal to the frequency of the vehicle, resulting in resonance.

[0189] The amplitude sensor 820 is used to collect the vibration amplitude of the parking air conditioner 800 and monitor the vibration state of the parking air conditioner 800 when the compressor 810 is running.

[0190] Understandably, after the compressor 810 starts running, the compressor 810 is the main source of vibration in the parking air conditioner 800. An amplitude sensor 820 can be installed on or near the compressor 810 to monitor the vibration state of the parking air conditioner 800, determine whether the parking air conditioner 800 resonates with the vehicle, and determine whether there is a risk of damage or breakage to the components and pipes in the parking air conditioner 800.

[0191] like Figure 7 As shown, the control device 700 of the parking air conditioner 800 includes:

[0192] The first processing module 710 is used to obtain the first vibration amplitude of the parking air conditioner 800 through the amplitude sensor 820 when the compressor 810 is running at the first target frequency. The first target frequency is one of a plurality of target operating frequencies in the target frequency set. The target operating frequency is located within the operating frequency range of the compressor 810. The number of frequencies in the target frequency set is less than the number of frequencies in the operating frequency range.

[0193] The second processing module 720 is used to adjust the operating frequency of the compressor 810 when the first vibration amplitude is greater than or equal to the target amplitude threshold, and to obtain the second vibration amplitude of the parking air conditioner 800 after the compressor 810 adjusts its operating frequency.

[0194] The third processing module 730 is used to determine the second target frequency of the compressor 810 based on the second vibration amplitude and the target amplitude threshold, and to control the compressor 810 to operate at the second target frequency.

[0195] According to the control device 700 of the parking air conditioner 800 provided in the embodiments of this application, by acquiring the first vibration amplitude corresponding to the compressor 810 operating at the first target frequency, monitoring the vibration state of the parking air conditioner 800, adjusting the operating frequency of the compressor 810 in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor 810 is controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon of the parking air conditioner 800 when it is installed in different vehicles or when the vehicle is driving under different road conditions, thereby improving the operational reliability of the parking air conditioner 800.

[0196] In some embodiments, the second processing module 720 is used to adjust the operating frequency of the compressor 810, including:

[0197] Determine the frequency adjustment amount corresponding to the first vibration amplitude;

[0198] The operating frequency of compressor 810 is adjusted according to the frequency adjustment amount.

[0199] In some embodiments, the third processing module 730 is configured to determine a second target frequency of the compressor 810 based on the second vibration amplitude and the target amplitude threshold, including:

[0200] The second vibration amplitude is compared with the target amplitude threshold, and the comparison result determines whether to continue adjusting the operating frequency of compressor 810.

[0201] If it is determined that the operating frequency of compressor 810 should be adjusted, the operating frequency of compressor 810 is adjusted, and a second vibration amplitude is obtained for each adjustment of the operating frequency of compressor 810.

[0202] If it is determined that the operating frequency of compressor 810 will be stopped, a second target frequency will be determined.

[0203] In some embodiments, the third processing module 730 is configured to determine a second target frequency when it is determined that the operating frequency of the compressor 810 will be stopped, including:

[0204] If the second vibration amplitude corresponding to the current operating frequency of compressor 810 is less than the target amplitude threshold, it is determined to stop adjusting the operating frequency of compressor 810 and take the current operating frequency of compressor 810 as the second target frequency.

[0205] In some embodiments, the third processing module 730 is configured to determine a second target frequency when it is determined that the operating frequency of the compressor 810 will be stopped, including:

[0206] When the compressor 810 adjusts its frequency within the operating frequency range, and all of the multiple second vibration amplitudes are greater than or equal to the target amplitude threshold, the operating frequency corresponding to the minimum value among the multiple second vibration amplitudes is taken as the second target frequency.

[0207] In some embodiments, the target operating frequency is determined based on the load demand of the parking air conditioner 800.

[0208] In some embodiments, the difference between two adjacent target operating frequencies in the target frequency set is equal.

[0209] In some embodiments, during the process of adjusting the operating frequency of the compressor 810, the priority of adjusting the operating frequency of the compressor 810 to be lower is greater than the priority of adjusting the operating frequency of the compressor 810 to be higher.

[0210] In some embodiments, after obtaining the first vibration amplitude of the parking air conditioner 800, the second processing module 720 is further configured to maintain the current operating frequency of the compressor 810 if the first vibration amplitude is less than the target amplitude threshold.

[0211] The control device 700 of the parking air conditioner 800 in this embodiment can be an electronic device or a component in an electronic device, such as an integrated circuit or a chip.

[0212] The control device 700 for the parking air conditioner 800 provided in this application embodiment can achieve... Figures 1 to 6 The various processes implemented in the method implementation examples will not be described again here to avoid repetition.

[0213] This application embodiment also provides a parking air conditioner 800, which is installed in a vehicle.

[0214] like Figure 8As shown, the parking air conditioner 800 includes a compressor 810, an amplitude sensor 820, and a control device 700 as described above. The control device 700 is connected to the compressor 810 and the amplitude sensor 820.

[0215] In practice, the parking air conditioner 800 can be used in vehicles such as transport trucks, RVs, and buses to provide a comfortable environment for the driver's cab.

[0216] The parking air conditioner 800 may include components such as a compressor 810, a heat exchanger, and a throttling element. The compressor 810, the outdoor heat exchanger, the throttling element, and the indoor heat exchanger are connected in sequence to form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit to realize the cooling or heating function of the parking air conditioner 800.

[0217] The amplitude sensor 820 is used to collect the vibration amplitude of the parking air conditioner 800 and monitor the vibration state of the parking air conditioner 800 when the compressor 810 is running.

[0218] According to the parking air conditioner 800 provided in the embodiments of this application, by acquiring the first vibration amplitude corresponding to the compressor 810 operating at the first target frequency, monitoring the vibration state of the parking air conditioner 800, adjusting the operating frequency of the compressor 810 in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor 810 is controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon of the parking air conditioner 800 when it is installed in different vehicles or when the vehicle is driving under different road conditions, thereby improving the operational reliability of the parking air conditioner 800.

[0219] This application also provides a vehicle.

[0220] The vehicle includes a body 900 and a parking air conditioner 800 as described above, which is mounted on the body 900.

[0221] In practice, the parking air conditioner 800 can be used in vehicles such as transport trucks, RVs, and buses to provide a comfortable environment for the driver's cab.

[0222] Taking a transport truck as an example, such as Figure 9 As shown, the parking air conditioner 800 is installed on the top of the vehicle body 900. The parking air conditioner 800 is connected to the cab through a gas pipe. The parking air conditioner 800 adjusts and controls the temperature, humidity, airflow and other parameters of the ambient air in the cab.

[0223] According to the vehicle provided in this application embodiment, by acquiring the first vibration amplitude corresponding to the compressor 810 operating at the first target frequency, monitoring the vibration state of the parking air conditioner 800, adjusting the operating frequency of the compressor 810 in a timely manner, and combining the feedback of the second vibration amplitude to optimize the operating frequency, the compressor 810 is controlled to operate at the second target frequency. This can effectively limit the resonance phenomenon of the parking air conditioner 800 when it is installed in different vehicles or when the vehicle is driving under different road conditions, thereby improving the operational reliability of the parking air conditioner 800.
