Abstract
Description

[0002] Air conditioning equipment typically has a service life of over 10 years. To ensure stability during long-term use, the stability and reliability of the air conditioning refrigeration system must be guaranteed during the manufacturing process. Among the four main components of air conditioning equipment—evaporator, condenser, compressor, and throttling device—both the evaporator and condenser contain copper pipes. During the manufacturing process of air conditioners containing evaporators or condensers (indoor or outdoor units), when the copper pipes are welded, the inner wall of the copper pipes reacts with oxygen at high temperatures, producing oxide scale that can block the pipe passages, affecting the normal flow of refrigerant and causing the refrigeration system to malfunction. To avoid this oxidation reaction, a certain flow of nitrogen gas must be injected into the copper pipes before welding to expel the oxygen.
[0003] Currently, when purging copper pipes of air conditioners with nitrogen, the nitrogen purging process is mostly carried out manually after setting the corresponding nitrogen purging parameters (e.g., nitrogen flow rate). This manual setting method is prone to problems such as the manually set nitrogen purging parameters being unsuitable for the corresponding air conditioner or being set incorrectly, resulting in unstable nitrogen purging effect and quality risks. Furthermore, the manual setting method is easily affected by subjective factors such as the work experience of the staff, making it difficult to guarantee the nitrogen purging effect of the air conditioner.

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

Detailed Implementation
[0018] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0019] During the manufacturing process of air conditioners (indoor or outdoor units) containing evaporators or condensers, the copper pipes are welded. At high temperatures, the inner wall of the copper pipes reacts with the oxygen inside the pipes, producing oxide scale that can block the pipe passages. This can affect the normal flow of refrigerant in the pipes and cause the refrigeration system to malfunction. To avoid this oxidation reaction, a certain flow of nitrogen gas must be injected into the copper pipes before welding to expel the oxygen inside.
[0020] Currently, when purging copper pipes of air conditioners with nitrogen, the nitrogen purging process is mostly carried out manually after setting the corresponding nitrogen purging parameters (e.g., nitrogen flow rate). This manual setting method is prone to problems such as the manually set nitrogen purging parameters being unsuitable for the corresponding air conditioner or being set incorrectly, resulting in unstable nitrogen purging effect and quality risks. Furthermore, the manual setting method is easily affected by subjective factors such as the work experience of the staff, making it difficult to guarantee the nitrogen purging effect of the air conditioner.
[0021] To address the problems in the prior art, this application provides a nitrogen filling control method, device, electronic device, and storage medium. It can determine the required nitrogen flow rate for the copper pipes of different air conditioners and control the nitrogen filling system to perform nitrogen filling operations on the air conditioner's copper pipes based on this flow rate. This effectively avoids problems such as incompatible or incorrectly set nitrogen filling parameters, and also avoids the influence of subjective factors by operators, ensuring the nitrogen filling effect and quality of the air conditioner.
[0022] Example 1 See Figure 1 , Figure 1 This is a schematic diagram of a partial structure of the nitrogen-filling system provided in this application embodiment. The nitrogen-filling control method of this application embodiment is applied to the nitrogen-filling system, which can be used to fill the copper pipes of an air conditioner with nitrogen. The nitrogen-filling system includes a nitrogen source, a gas flow controller, a pressure sensor, an automatic disconnect connector, an air conditioner docking valve, a solenoid valve, and a compressed air source. The nitrogen source refers to a nitrogen supply device that can provide nitrogen. The gas flow controller is used to control the nitrogen-filling flow rate of the nitrogen-filling system. The pressure sensor is used to collect the actual nitrogen pressure when the nitrogen-filling system fills the copper pipes of the air conditioner with nitrogen. The automatic disconnect connector is used to connect to one connector of the air conditioner docking valve, and the other connector of the air conditioner docking valve is used to connect to the air conditioner. The compressed air source refers to a compressed air supply device that can provide compressed air. The solenoid valve controls whether the compressed air supplied by the compressed air source can be delivered to the automatic disconnect connector by opening or closing. In addition, the nitrogen-filling system may also be equipped with a flow sensor, which is used to collect the actual nitrogen-filling flow rate when the nitrogen-filling system fills the copper pipes of the air conditioner with nitrogen.
[0023] It should be noted that in other embodiments, the nitrogen filling system may also adopt other structures. For example, the nitrogen filling system may not be equipped with a pressure sensor, solenoid valve, and compressed air source, and the automatic disconnect connector and the air conditioner docking valve may be changed to a manually detachable connection structure; or, the nitrogen filling system may not be equipped with a pressure sensor; or, the nitrogen filling system may not be equipped with a solenoid valve and compressed air source, and the automatic disconnect connector and the air conditioner docking valve may be changed to a manually detachable connection structure; other structures that the nitrogen filling system may adopt will not be described in detail here.
[0024] The nitrogen filling control method described in this application embodiment can be applied to computer equipment such as industrial computers, which are connected to the nitrogen filling system.
[0025] See Figure 2 , Figure 2 This is a schematic flowchart of the nitrogen filling control method provided in the embodiments of this application.
[0026] This application provides a nitrogen filling control method, including the following steps: Step S110: Obtain the pipe size information of the copper pipe of the target air conditioner.
[0027] In this embodiment, the target air conditioner can be an indoor unit or an outdoor unit. Understandably, the target air conditioner is an indoor or outdoor unit that is still in the production stage and has not yet been completed. The copper pipes of the target air conditioner refer to the copper pipes of the evaporator of the indoor unit or the copper pipes of the condenser of the outdoor unit. In this embodiment, the pipe size information of the copper pipe of the target air conditioner may include pipe size parameters such as pipe diameter and pipe length.
[0028] For example, the pipe size information of the target air conditioner's copper pipes can be pipe size information entered by the staff; or it can be obtained by matching according to the specifications and / or model of the evaporator or condenser. In this way, a data table of associated information of pipe size information corresponding to different evaporators or condensers can be established in advance. In this way, during matching, it can be matched according to the specifications and / or model of the evaporator or condenser. Optionally, the specifications and / or model of the evaporator or condenser can be entered by the staff, or it can be obtained by scanning a barcode or by recognizing an image captured by a camera.
[0029] Step S120: Determine the required nitrogen flow rate for the copper pipes of the target air conditioner based on the pipe size information.
[0030] In this embodiment, the required nitrogen flow rate for the copper pipe of the target air conditioner can be determined based on the pipe diameter and pipe length; Understandably, the nitrogen flow rate required for the copper pipes of the target air conditioner, that is, the nitrogen flow rate required by the nitrogen filling system to perform nitrogen filling operation on the copper pipes of the target air conditioner, is controlled by the gas flow controller of the aforementioned nitrogen filling system.
[0031] Step S130: Based on the nitrogen flow rate, control the nitrogen filling system to perform nitrogen filling operation on the copper pipes of the target air conditioner.
[0032] In this embodiment, when the nitrogen filling system is controlled to perform nitrogen filling operation on the copper pipe of the target air conditioner according to the nitrogen filling flow rate, the nitrogen filling flow rate of the nitrogen filling system during the nitrogen filling operation on the copper pipe of the target air conditioner is controlled by the gas flow controller of the nitrogen filling system.
[0033] Optionally, when controlling the nitrogen charging system to charge the copper pipes of the target air conditioner with nitrogen, a predetermined nitrogen charging time can be used. This predetermined nitrogen charging time can be determined based on the time required for nitrogen to fully charge the copper pipes of the target air conditioner. For example, it can be determined based on the nitrogen charging flow rate and the specifications of the copper pipes of the target air conditioner. In this way, a data table of correlation information for nitrogen charging time corresponding to different nitrogen charging flow rates and different specifications of copper pipes of the target air conditioner can be suggested in advance. Thus, during matching, the nitrogen charging time can be matched according to different nitrogen charging flow rates and different specifications of copper pipes of the target air conditioner.
[0034] The nitrogen filling control method of this application embodiment determines the required nitrogen filling flow rate of the copper pipe of the target air conditioner by acquiring the pipe size information of the copper pipe of the target air conditioner, and controls the nitrogen filling system to perform nitrogen filling operation on the copper pipe of the target air conditioner according to the nitrogen filling flow rate. In this way, the required and appropriate nitrogen filling flow rate of the copper pipe of the corresponding air conditioner can be dynamically determined according to different air conditioners. Compared with the method of manually setting nitrogen filling parameters, it can effectively avoid the problem of manually set nitrogen filling parameters not being suitable for the corresponding air conditioner or being set incorrectly, and avoid the influence of subjective factors of the staff, thus ensuring the nitrogen filling effect and quality of the air conditioner.
[0035] See Figure 3 As an optional implementation, step S110, obtaining the pipe size information of the copper pipe of the target air conditioner, may include: Step S111: Obtain the identification code of the target air conditioner; Step S112: Obtain the pipe structure design drawings of the copper pipes of the target air conditioner according to the identification code of the target air conditioner; Step S113: Obtain the pipe size information of the copper pipe of the target air conditioner according to the pipe structure design drawings.
[0036] In this implementation, the identification code of the target air conditioner can be the MES barcode of the target air conditioner. MES stands for Manufacturing Execution System, which is a production information management system for the shop floor execution layer of manufacturing enterprises. The MES barcode is a unique identification code for each air conditioner. For example, the identification code of the target air conditioner can be obtained by a barcode scanner, or by a camera capturing an image containing the MES barcode of the target air conditioner.
[0037] Specifically, based on the identification code of the target air conditioner, it is possible to determine which air conditioner it is, its specifications and model. Then, the pipe structure design drawings of the target air conditioner's copper pipes can be obtained from a pre-established database of air conditioner and its corresponding pipe structure design drawings. Understandably, these pipe structure design drawings contain the pipe size information of the target air conditioner's copper pipes, and thus the pipe size information of the target air conditioner's copper pipes can be obtained from the pipe structure design drawings.
[0038] In this method, the pipe structure design drawings of the copper pipes of the target air conditioner are obtained through the identification code of the target air conditioner, and then the pipe size information of the copper pipes of the target air conditioner is obtained in a relatively convenient, accurate and fast way. This can ensure the accuracy of the nitrogen filling flow rate required for the copper pipes of the target air conditioner, thereby better guaranteeing the nitrogen filling effect and quality of the air conditioner.
[0039] See Figure 4 As an optional implementation, step S120, determining the required nitrogen flow rate for the copper pipes of the target air conditioner based on the pipe size information, includes: Step S121: Calculate the pipe volume of the copper pipe of the target air conditioner based on the pipe diameter and pipe length; Step S122: Match the required nitrogen flow rate of the copper pipe of the target air conditioner according to the pipe volume of the target air conditioner.
[0040] In this implementation, a data table of associated information for the required nitrogen flow rate corresponding to different copper pipe volumes can be pre-established. Thus, when matching the required nitrogen flow rate of the copper pipe of the target air conditioner based on the pipe volume of the target air conditioner, the required nitrogen flow rate of the copper pipe of the target air conditioner can be obtained based on the data table of associated information.
[0041] This method allows for a relatively quick and accurate determination of the required nitrogen flow rate for the copper pipes of the target air conditioner, thereby better ensuring the nitrogen filling effect and quality of the air conditioner.
[0042] As an optional implementation, the nitrogen filling control method of this application embodiment, after controlling the nitrogen filling system to perform nitrogen filling operation on the copper pipes of the target air conditioner according to the nitrogen filling flow rate, may further include the following steps: Obtain the actual nitrogen pressure and actual nitrogen flow rate when the nitrogen filling system performs nitrogen filling operation on the copper pipes of the target air conditioner; Based on the actual nitrogen pressure and actual nitrogen flow rate, determine whether the nitrogen filling operation of the target air conditioner's copper pipes meets the standards. If the nitrogen filling system meets the requirements for filling the copper pipes of the target air conditioner, the nitrogen filling operation will be completed after the scheduled nitrogen filling time. If the nitrogen filling system fails to meet the nitrogen filling standards for the copper pipes of the target air conditioner, the nitrogen filling system should be controlled to refill the copper pipes of the target air conditioner with nitrogen.
[0043] In this implementation, the actual nitrogen pressure and actual nitrogen flow rate when the nitrogen filling system fills the copper pipes of the target air conditioner can be obtained from the data collected by the pressure sensor and flow sensor of the nitrogen filling system.
[0044] For example, when determining whether the nitrogen filling operation of the nitrogen filling system for the copper pipes of the target air conditioner meets the standard based on the actual nitrogen pressure and the actual nitrogen filling flow rate, the actual nitrogen pressure and the actual nitrogen filling flow rate can be compared with the corresponding preset nitrogen pressure threshold range and preset nitrogen filling flow rate threshold range, respectively. If the actual nitrogen pressure and the actual nitrogen filling flow rate are both within the preset nitrogen pressure threshold range and the preset nitrogen filling flow rate threshold range, then the nitrogen filling operation of the nitrogen filling system for the copper pipes of the target air conditioner is considered to be compliant. If either the actual nitrogen pressure or the actual nitrogen filling flow rate is not within the preset nitrogen pressure threshold range or the preset nitrogen filling flow rate threshold range, then the nitrogen filling operation of the nitrogen filling system for the copper pipes of the target air conditioner is considered to be non-compliant. The preset nitrogen filling flow rate threshold range can be set according to the nitrogen filling flow rate required by the copper pipes of the target air conditioner, and the preset nitrogen pressure threshold range can be matched according to the nitrogen filling flow rate required by the copper pipes of the target air conditioner, or it can be matched according to the nitrogen filling flow rate threshold range.
[0045] Understandably, the nitrogen filling operation is completed after the predetermined nitrogen filling time, that is, the nitrogen filling system stops supplying nitrogen; the nitrogen filling system is controlled to refill the copper pipes of the target air conditioner with nitrogen, that is, the nitrogen filling system is controlled to refill the copper pipes of the target air conditioner with nitrogen again at the required nitrogen filling flow rate. Optionally, when the nitrogen filling system is controlled to refill the copper pipes of the target air conditioner with nitrogen, it can continue until the nitrogen filling operation of the copper pipes of the target air conditioner meets the standard.
[0046] The above method allows for more effective and accurate control of the nitrogen charging operation of the copper pipes of the target air conditioner by the nitrogen charging system. The nitrogen charging operation is completed after the predetermined charging time, and the supply of nitrogen is stopped, reducing nitrogen waste. Furthermore, if the nitrogen charging operation of the copper pipes of the target air conditioner fails to meet the standards, the nitrogen charging system can be controlled to recharge the copper pipes of the target air conditioner, thus better ensuring the nitrogen charging effect and quality of the target air conditioner.
[0047] Furthermore, as a preferred embodiment, the nitrogen filling control method of this application may further include the following steps after the nitrogen filling operation is completed after a predetermined nitrogen filling time: The solenoid valve is opened, and the compressed air source is controlled to supply compressed air to the automatic disconnector, so that the automatic disconnector is pushed out and separated from the air conditioner docking valve.
[0048] Specifically, the automatic disconnector and the air conditioner docking valve can be assembled using a quick-connect fitting. The automatic disconnector is female, and the air conditioner docking valve is male. The male and female fittings are locked together by a retaining spring. Since the automatic disconnector is connected to a compressed air source through a pipeline, after the nitrogen filling operation is completed, the compressed air supplied by the compressed air source is introduced into the automatic disconnector by controlling the solenoid valve to open. The air pressure pushes open the retaining spring, causing the automatic disconnector to quickly separate from the air conditioner docking valve.
[0049] In the above method, after the nitrogen filling operation is completed, the automatic disconnector can be automatically pushed out and separated from the air conditioner docking valve without the need for the staff to manually disassemble the automatic disconnector from the air conditioner docking valve. This facilitates the work of the staff, improves the efficiency of nitrogen filling operation, and increases the efficiency of nitrogen filling operation and production of batch air conditioners.
[0050] Furthermore, as a preferred embodiment, the nitrogen filling control method of this application may further include the following steps: The actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance judgment information are uploaded to the MES system so that the MES system can associate the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance judgment information with the target air conditioner.
[0051] By uploading the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance judgment information to the MES system, the nitrogen charging operation of the air conditioner can be recorded and stored. Furthermore, the MES system can associate the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance judgment information with the target air conditioner, which facilitates the monitoring, management, and subsequent traceability of the nitrogen charging operation of the air conditioner.
[0052] Furthermore, as a preferred embodiment, the nitrogen filling control method of this application may further include the following steps: Send the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance assessment information to the relevant staff to notify them.
[0053] For example, when sending the actual nitrogen pressure, the required nitrogen flow rate, the actual nitrogen flow rate, and the corresponding compliance judgment information to the relevant personnel, it can be sent to the relevant personnel via email, or by sending a message to the relevant personnel's terminal or by pushing a notification.
[0054] By sending the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance assessment information to the relevant personnel, the personnel can be informed of the nitrogen charging operation of the air conditioner in real time and in a timely manner. This facilitates the monitoring, management, and tracking of the nitrogen charging operation, which is beneficial to the implementation of the nitrogen charging operation and better ensures the effectiveness and quality of the nitrogen charging operation.

[0058] The nitrogen charging control device provided in this application determines the required nitrogen charging flow rate for the copper pipes of the target air conditioner by acquiring the pipe size information of the target air conditioner, and controls the nitrogen charging system to perform nitrogen charging operation on the copper pipes of the target air conditioner according to the nitrogen charging flow rate. In this way, the required and appropriate nitrogen charging flow rate for the copper pipes of different air conditioners can be dynamically determined for nitrogen charging operation. Compared with the method of manually setting nitrogen charging parameters, it can effectively avoid the problems of manually set nitrogen charging parameters not being suitable for the corresponding air conditioner or being set incorrectly, and avoid the influence of subjective factors of the staff, thus ensuring the nitrogen charging effect and quality of the air conditioner.

If the nitrogen filling system fails to meet the nitrogen filling standards for the copper pipes of the target air conditioner, the nitrogen filling system should be controlled to refill the copper pipes of the target air conditioner with nitrogen.
[0062] Furthermore, preferably, the control module 530 can also be used to control the solenoid valve to open and control the compressed air source to deliver compressed air to the automatic disconnector after the nitrogen filling operation is completed after the predetermined nitrogen filling time, so as to push the automatic disconnector out of the air conditioner docking valve.
[0063] Furthermore, as a preferred embodiment, the nitrogen filling control device of this application also includes an information transmission module, which is used to upload the actual nitrogen pressure, the required nitrogen filling flow rate, the actual nitrogen filling flow rate and the corresponding compliance judgment information to the MES system, so that the MES system can associate the actual nitrogen pressure, the required nitrogen filling flow rate, the actual nitrogen filling flow rate and the corresponding compliance judgment information with the target air conditioner. Additionally, it can be used to send the actual nitrogen pressure, required nitrogen flow rate, actual nitrogen flow rate, and corresponding compliance judgment information to the relevant personnel to notify them.
