[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0041] At present, manufacturers have two main solutions to the problem of excessive pressure in air conditioning systems:

[0042] First, the overvoltage is determined by detecting the temperature difference of the air conditioning pipe in the air conditioning system or the current of the compressor in the air conditioning system. However, this solution has the problem of false alarm of the system, which affects the normal use of users.

[0043] Second, by adding a sensor switch or pressure sensor to the air conditioning system to detect whether there is overpressure. However, this solution adds components to the air conditioning pipeline, which not only increases the cost of the air conditioning unit, but also affects the stress and strain of the pipeline, affecting the long-term reliable operation of the air conditioning system.

[0044] In order to solve the above problems, the embodiments of the present disclosure provide a control method, device, equipment and storage medium for a pressure relief device. The specific structures of the pressure relief device and the terminal device are introduced by taking the application of the pressure relief device to a terminal device with a compressor as an example, but this does not constitute a limitation. The above terminal device includes but is not limited to air conditioning equipment, refrigeration equipment or other equipment with compressor functions, which can be determined according to actual conditions and is not limited by the present disclosure. Please refer to Figure 1 is a schematic structural diagram of a compressor including a pressure relief device according to an exemplary embodiment.

[0045] like Figure 1 The compressor shown may include a pressure relief device 100, a compressor body 101, a compressor motor 102, an upper cylinder air cover 103, a lower cylinder air cover 104, a compressor shaft 105, a compressor rotor 106, an exhaust port 107, an air intake port 108, and a liquid reservoir 109. Those skilled in the art will appreciate that the device structure shown in the figure does not constitute a limitation on the compressor, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently. Figure 1 The various components of the compressor shown are introduced in detail. Among them:

[0046] The pressure relief device 100 is shown by the dotted line in the figure, and the pressure relief device 100 may include a pressure relief channel 1001 and a sealing component 1002. The pressure relief channel 1001 may be arranged in the upper cylinder gas cover 103 of the compressor. The present disclosure does not limit the shape of the pressure relief channel. For example, the pressure relief channel may be a double L-shaped pressure relief channel, or it may be adjusted according to actual conditions. The pressure relief channel 1001 may be sealed by the sealing component 1002 to divide / form two chambers of the corresponding internal space of the compressor, which may be referred to as the first chamber 1004 and the second chamber 1005, respectively. The present disclosure may realize the connection or blocking of the first chamber 1004 and the second chamber 1005 by controlling the sealing component 1002. Among them, the first chamber 1004 may be used for gas discharge, which may also be referred to as an exhaust chamber (referred to as an exhaust chamber). The second chamber 1005 may be used for gas inhalation and / or gas compression, which may also be referred to as a compression chamber or an air intake chamber (referred to as a compression chamber). The present disclosure does not limit the specific type of the sealing component 1002 , for example, it may include but is not limited to a sealing plate, a pressure pin or other custom sealing components.

[0047] Among them, the upper cylinder gas cover 103 of the present disclosure can also be called the upper end cover of the cylinder, and the lower cylinder gas cover 104 can also be called the lower end cover of the cylinder. The closed space formed between the upper cylinder gas cover 103 and the lower cylinder gas cover 104 is a compression chamber (that is, the second chamber 1004 mentioned above), which is connected to the suction port 108 through the suction channel to suck the external gas into the compression chamber for gas compression. Specifically, when the compressor is working, the compressor motor 102 runs, driving the compressor shaft 105 and the compressor rotor 106 to rotate and work to compress the gas sucked into the compression chamber. The liquid generated after compression can flow into the liquid reservoir 109 for storage, and the waste gas or excess gas generated after compression can flow through the exhaust chamber (that is, the first chamber 1005 mentioned above) and discharge through the exhaust port 107. Among them, the exhaust chamber is the white area located at the upper end of the upper cylinder gas cover 103 in the figure. The present disclosure does not make too many details and limitations on other components in the compressor.

[0048] In some optional embodiments, the pressure relief device 100 may further include a control switch 1003 (not shown). The control switch 1003 is disposed on the sealing component 1002, and is used to control whether the sealing component 1002 connects or blocks (also referred to as disconnecting or isolating) the first chamber 1004 and the second chamber 1005. The present disclosure does not limit the specific type of the control switch 1003, for example, it may include but is not limited to a solenoid valve, or other switches. The present disclosure describes in detail below the specific implementation of how to control the control switch 1003 and the sealing component 1002 to connect or block the first chamber 1004 and the second chamber 1005, and will not be repeated here.

[0049] For example, taking the control switch 1003 as a solenoid valve and the sealing component 1003 as a pin, when the indoor pressure (i.e., gas pressure) in the first chamber 1004 is greater than the preset pin pressure threshold, the pin can be pushed downward due to the high gas pressure to connect the first chamber and the second chamber. Alternatively, when the indoor pressure (i.e., gas pressure) in the first chamber 1004 is greater than the preset pin pressure threshold, the solenoid valve can be opened to connect the first chamber and the second chamber to balance the pressure on the suction side and the exhaust side of the compressor, so that the pressure in the compressor is consistent, avoiding the compressor from overloading due to overpressure, resulting in equipment wear, or unreliable and unsafe equipment operation due to excessive pressure, or explosion of the compressor due to after-sales operation errors.

[0050] Based on the above examples, see Figure 2 FIG. 1 is a flow chart of a control method of a pressure relief device according to an exemplary embodiment. Figure 2 The method shown can be applied to Figure 1 In the pressure relief device 100 shown in FIG. 1 , the structure of the pressure relief device 100 may be referred to in the aforementioned Figure 1 The relevant introduction in the above-mentioned embodiment will not be repeated here. Figure 2 The method shown may include the following implementation steps:

[0051] S201, obtaining working parameters of the pressure relief device 100.

[0052] The above-mentioned working parameters disclosed in the present invention refer to relevant parameters during the operation of the above-mentioned pressure relief device 100 or the equipment where the above-mentioned pressure relief device 100 is located, which may include but are not limited to, for example, any one or more combinations of the following: the indoor pressure of the first chamber 1004 (i.e., gas pressure), the indoor temperature of the first chamber 1004 (i.e., gas temperature), the indoor temperature of the second chamber 1005, the working current of the pressure relief device 100 or the equipment where it is located (such as a compressor) or other custom parameters, etc.

[0053] S202 . When the working parameters of the pressure relief device 100 meet preset conditions, the sealing component 1002 is controlled to connect the first chamber 1004 and the second chamber 1005 to balance the indoor pressures of the first chamber 1004 and the second chamber 1005 .

[0054] When the above working parameters meet the preset conditions, the present disclosure can control the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005 to balance the pressure difference between the first chamber 1004 and the second chamber 1005, so as to avoid the overload working condition of the chamber overpressure, equipment wear, unreliable or unsafe operation, etc. The description of the respective contents of the pressure relief device 100, the sealing component 1002, the first chamber 1004 and the second chamber 1005 can be referred to the above Figure 1 The relevant introduction in the embodiments will not be repeated here.

[0055] The above-mentioned preset conditions are overpressure judgment conditions that are customized according to actual conditions, which may include but are not limited to any one or more of the following combinations: the indoor pressure of the first chamber 1004 is greater than the preset pressure threshold, the difference between the indoor temperature of the first chamber 1004 and the indoor temperature of the second chamber 1005 is not within the preset temperature range, the working current of the pressure relief device is greater than the preset current threshold or other customized overpressure judgment conditions. The above-mentioned preset pressure threshold is a pressure threshold that is customized according to actual conditions, such as an empirical value that can be set based on user experience, or a statistical value that can be calculated based on a series of experimental data. The above-mentioned preset temperature range is also a temperature range that is customized according to actual conditions, and the above-mentioned preset current threshold is also a current threshold that is customized according to actual conditions. The present disclosure does not make too many restrictions and details on this.

[0056] The present disclosure does not limit the control implementation method of the sealing component 1002. Taking the sealing component 1002 as a pin as an example, when it is determined that the above working parameters meet the above preset conditions, the pin can be pushed downward due to the overpressure in the first chamber, thereby connecting the above first chamber 1004 and the above second chamber 1005, so as to connect the high-pressure chamber and the low-pressure chamber, thereby balancing the pressure difference between the intake side and the exhaust side, so that the pressures in the two chambers of the pressure relief device 100 are consistent, avoiding problems such as equipment wear caused by high pressure.

[0057] In some optional embodiments, the pressure relief device 100 further includes a control switch 1003, which is disposed on the sealing component 1002 to control whether the sealing component 1002 connects or blocks the first chamber 1004 and the second chamber 1005. In the specific implementation process, when the present disclosure determines that the working parameters meet the preset conditions, the control switch 1003 can be controlled to be opened to control the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005 to balance the pressure difference between the two chambers. In practical applications, by default, the sealing component 1002 or the control switch 1003 is in a closed state to block the first chamber 1004 and the second chamber 1005, so that the first chamber 1004 and the second chamber 1005 become two independent, non-connected chambers.

[0058] In some optional embodiments, during the operation of the pressure relief device 100, the present disclosure may perform the above steps S201 and S202 in real time or periodically according to actual needs. After controlling the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005, the present disclosure may detect the current working parameters of the pressure relief device 100 again after a preset period of time to determine whether to control the sealing component 1004 to block the first chamber 1004 and the second chamber 1005. In a specific implementation, when the working parameters of the pressure relief device 100 do not meet the preset conditions, the present disclosure may control the sealing component 1002 to block the first chamber 1004 and the second chamber 1005, or control the closing of the control switch 1003 to block the first chamber 1004 and the second chamber 1005.

[0059] In some optional embodiments, when the pressure relief device 100 is detected to be in a target state, the present disclosure can control the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005. Specifically, the sealing component 1002 can be directly controlled or the control switch 1003 can be controlled to open to control the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005. The target state is a state customized according to actual conditions, which may include but is not limited to any one or a combination of multiple of the following states: shutdown, restart, and abnormal fault, etc.

[0060] Optionally, when the pressure relief device 100 is detected to have the target condition, the present disclosure may control the sealing component 1002 to connect the first chamber 1004 and the second chamber 1005 after a preset period of time. For example, when the pressure relief device 100 is shut down due to an abnormal fault, the control switch 1003 may be opened after 3 seconds to connect the first chamber 1004 and the second chamber 1005 to balance the air pressure in the two chambers. When the pressure relief device 100 returns to normal, the control switch 1003 may be closed to block the first chamber 1004 and the second chamber 1005, etc.

[0061] By implementing the embodiments of the present disclosure, it is not only possible to effectively reduce the problems of high-pressure operation of the pressure relief device causing equipment wear or after-sales explosion accidents, but also to improve the reliability and safety of the equipment operation caused by the overload working condition of the pressure relief device due to overpressure. In a specific implementation, the working parameters of the pressure relief device can be obtained. The pressure relief device includes a pressure relief channel and a sealing component. The pressure relief channel is sealed by the sealing component to form a first chamber and a second chamber; when the working parameters of the pressure relief device meet the preset conditions, the sealing component is controlled to connect the first chamber and the second chamber to balance the indoor pressure of the first chamber and the second chamber. It can be seen that the present disclosure can control the sealing component to connect the first chamber and the second chamber when the working parameters of the pressure relief device meet the preset conditions to balance the pressure difference between the two chambers, avoid the overload working condition of overpressure, and cause the equipment to wear, unsafe and unreliable equipment operation, etc., thereby helping to improve the reliability and safety of the operation of the pressure relief device.
