[0002] During compressor operation, refrigerant circulation is typically used to cool heat-generating components such as the motor. Because refrigerant circulation lowers the localized temperature of the compressor body or its mounting base, condensation can easily form in the compressor controller's installation environment when moisture from the outside air comes into contact with these low-temperature areas. In particular, when the controller is located on or near the compressor body, condensation can adhere to the controller housing, heat dissipation structures, or near the circuit board, leading to circuit board corrosion, decreased insulation performance, and even short-circuit faults, thus affecting the compressor controller's operational reliability and lifespan.
[0003] Therefore, how to reduce the risk of condensate generation in the compressor controller installation environment and avoid condensate from corroding or short-circuiting the controller circuit is a technical problem that urgently needs to be solved. Summary of the Invention

[0026] As described in the background section, the installation environment of the compressor controller in the prior art is prone to condensation, which leads to circuit corrosion. In order to solve the above technical problems, the embodiments of this application provide a compressor anti-condensation control method, a compressor anti-condensation control device, a compressor, and a computer-readable storage medium.
[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0028] Figure 1 This is a flowchart of a compressor anti-condensation control method according to an embodiment of this application. Figure 1 As shown, the method includes the following steps:
[0029] Step S101: Obtain environmental parameters of multiple preset areas in the compressor, including temperature and humidity parameters.
[0030] Specifically, multiple preset zones are areas within the compressor that are pre-defined and require condensation risk monitoring. Temperature parameters characterize the hot or cold state of the corresponding preset zone, while humidity parameters characterize the moisture content in the air of the corresponding preset zone. By simultaneously acquiring both temperature and humidity parameters, it is possible to more accurately reflect whether each preset zone possesses the environmental conditions for condensation formation.
[0031] Step S102: Determine the target area based on the above environmental parameters. The target area is an area with a risk of condensation.
[0032] Specifically, after obtaining the environmental parameters of multiple preset areas, the system determines whether each preset area is prone to condensation based on the temperature and humidity parameters of each preset area, and identifies the preset areas with condensation risk as target areas.
[0033] Step S103: Control the heating module located in the corresponding preset area to operate according to the target area.
[0034] Specifically, after determining the target area, the heating module corresponding to the target area is controlled to operate, so that the heating module heats the corresponding preset area.
[0035] Through the above embodiments, by acquiring temperature and humidity parameters of multiple preset areas and determining target areas with condensation risk based on these parameters, the location in the compressor prone to condensation can be identified in a timely manner. Furthermore, by controlling the operation of the corresponding heating module according to the target area, targeted heating can be performed on the area with condensation risk, thereby increasing the temperature of that area, reducing the risk of condensation formation, preventing condensation from corroding the controller circuit, and improving the operational reliability and service life of the compressor controller.
[0036] In some embodiments, multiple preset zones are areas within the compressor that are prone to condensation risk and require environmental parameter monitoring and temperature regulation. Each preset zone may correspond to at least one heating module, or multiple adjacent preset zones may correspond to the same heating module. The heating module is located within the corresponding preset zone, or at a position capable of heating the corresponding preset zone, so that the heat generated during operation can act on the corresponding preset zone. During control, when a preset zone is determined to be a target zone based on environmental parameters, it indicates that the preset zone has a condensation risk. At this time, the heating module located at the corresponding position in the target zone is controlled to operate, thereby increasing the temperature of the target zone and reducing the likelihood of condensation. This allows for targeted heating of areas with condensation risk without continuously heating the entire area, thus improving the targeting of anti-condensation control and reducing energy consumption.
[0037] In some exemplary embodiments, determining the target area based on the above-mentioned environmental parameters includes: determining the preset area where the temperature parameter is less than a preset temperature value as the target area, or determining the preset area where the humidity parameter is greater than a preset humidity value as the target area.
[0038] Specifically, the temperature parameter of each preset area is compared with a preset temperature value. When the temperature parameter of a preset area is lower than the preset temperature value, it indicates that the temperature of that preset area is low, and water vapor in the outside air is more likely to condense in that area. Therefore, this preset area is identified as a target area. Alternatively, the humidity parameter of each preset area is compared with a preset humidity value. When the humidity parameter of a preset area is higher than the preset humidity value, it indicates that the water vapor content in the air surrounding that preset area is high, creating conditions for condensation. Therefore, this preset area is also identified as a target area. In other words, if a preset area meets either the condition of low temperature or high humidity, it can be considered to have a risk of condensation and is identified as a target area requiring anti-condensation control. This allows for timely identification of locations prone to condensation, providing a basis for subsequent targeted control of the heating module operation.
[0039] In the above embodiments, by defining the preset area where the temperature parameter is less than the preset temperature value or the humidity parameter is greater than the preset humidity value as the target area, it is possible to identify areas with condensation risk from two dimensions: excessively low temperature and excessively high humidity. This improves the accuracy and timeliness of condensation risk assessment, thereby facilitating subsequent targeted anti-condensation control of the area and reducing the risk of condensate generation and circuit corrosion.
[0040] In some embodiments, the preset temperature and preset humidity values are predetermined based on the actual operating environment of the compressor, the temperature variation range of the compressor housing or heat dissipation components, the humidity variation range of the environment surrounding the controller, and the conditions for condensation formation. Specifically, the preset temperature value is determined based on the critical temperature at which water vapor may condense in the controller installation environment; the preset humidity value is determined based on the critical humidity at which the water vapor content in the controller installation environment easily leads to condensation. Further, the preset temperature and preset humidity values can be determined through experimental calibration, historical operating data, or the target application environment of the compressor. For example, under different ambient temperatures, different ambient humidity levels, and different compressor operating conditions, multiple preset areas can be detected to determine whether condensation occurs, and the temperature and humidity parameters corresponding to the start or imminent formation of condensation can be used as the setting basis. This allows the control method to promptly determine the target area based on the actual condensation risk, thereby improving the accuracy of anti-condensation control.
[0041] In one optional solution, controlling the operation of the heating module located in the corresponding preset area according to the target area includes: determining the target heating module corresponding to the target area according to the preset correspondence between the target area and the heating module; and controlling the operation of the target heating module.
[0042] In the above embodiments, by pre-establishing the correspondence between target areas and heating modules, after identifying target areas with condensation risk, the target heating module for heating that target area can be quickly determined and its operation controlled. This enables targeted heating of areas with condensation risk, avoiding indiscriminate activation of all heating modules, improving the specificity of anti-condensation control, reducing energy consumption, and minimizing the risk of corrosion of compressor control circuits by condensate.
[0043] In some embodiments, a pre-established correspondence is established between multiple preset areas and heating modules. This correspondence represents the association between each preset area and a heating module capable of heating that preset area. That is, when a preset area is determined as a target area, a heating module capable of heating that target area is determined based on the pre-established correspondence between the target area and the heating module, and this heating module is designated as the target heating module. After determining the target heating module, the target heating module is controlled to operate, causing the target heating module to heat the target area or the corresponding preset area containing the target area, thereby increasing the temperature of that area and reducing the risk of condensation in that area.
[0044] In another optional embodiment, controlling the operation of the target heating module includes: obtaining the difference between a preset target temperature parameter and the temperature parameter of the target area; if the difference is greater than or equal to a first preset difference, controlling the target heating module to operate at a first power; if the difference is less than the first preset difference but greater than or equal to a second preset difference, controlling the target heating module to operate at a second power, wherein the first preset difference is greater than the second preset difference and the first power is greater than the second power; and if the difference is less than the second preset difference, controlling the target heating module to operate at a third power, wherein the third power is less than the second power.
[0045] In the above embodiments, by obtaining the difference between the preset target temperature parameter and the temperature parameter of the target area, and controlling the target heating module to operate at different power levels according to the magnitude of the difference, it is possible to rapidly heat up the target area with higher power when the temperature is low and the risk of condensation is high; as the target area gradually approaches the preset target temperature parameter, the heating power is reduced to avoid temperature overshoot caused by continuous high-power heating; and when the temperature of the target area is basically close to the preset target temperature parameter, the temperature is maintained at a lower power. Therefore, it is possible to balance anti-condensation effect, temperature control stability, and energy consumption control, while reducing the risk of condensate formation and circuit corrosion.
[0046] Specifically, the preset target temperature parameter is the desired temperature parameter for the target area. The aforementioned difference characterizes the degree of deviation between the current temperature of the target area and the preset target temperature. A larger difference indicates that the current temperature of the target area is further from the preset target temperature, resulting in a higher risk of condensation and requiring stronger heating. When the difference is greater than or equal to the first preset difference, it indicates that the temperature of the target area is significantly lower than the preset target temperature, requiring rapid heating. Therefore, the target heating module is controlled to operate at the first power to rapidly heat the target area and reduce the risk of condensation as quickly as possible. When the difference is less than the first preset difference but greater than or equal to the second preset difference, it indicates that the temperature of the target area has increased but has not yet reached the preset target temperature. In this case, the target heating module is controlled to operate at the second power. Since the first preset difference is greater than the second preset difference, and the first power is greater than the second power, the output power of the heating module decreases as the target area gradually approaches the preset target temperature, thus avoiding excessively high temperatures due to continuous high-power heating. When the difference is less than the second preset difference, it indicates that the temperature of the target area is close to the preset target temperature, and the risk of condensation is relatively reduced. Therefore, the target heating module is controlled to operate at the third power. Since the third power is less than the second power, the target heating module can maintain the temperature of the target area with lower power, reducing temperature fluctuations and energy consumption.
[0047] In some embodiments, the aforementioned preset target temperature parameter, first preset difference, and second preset difference can be predetermined based on the compressor's operating conditions, the condensation formation conditions of the preset area, the heating capacity of the heating module, and the controller's safe operating temperature range. The preset target temperature parameter is the desired temperature value for the target area, which can be determined based on the temperature at which condensation is unlikely to occur in the target area. For example, it can be determined based on the target area's critical condensation temperature, the range of ambient temperature and humidity changes, and the temperature changes of the compressor base or heat dissipation components during compressor operation, so that when the target area is heated to near the preset target temperature parameter, the risk of condensation formation can be reduced. The first preset difference is used to determine whether the current temperature of the target area is significantly lower than the preset target temperature parameter. When the difference between the preset target temperature parameter and the temperature parameter of the target area is greater than or equal to the first preset difference, it indicates that the temperature of the target area is too low and the risk of condensation is high, requiring rapid heating with higher power. Therefore, the first preset difference is predetermined based on the rated power of the heating module, the heating requirement of the target area, and the allowable heating rate. The second preset difference is used to determine whether the target area is approaching the preset target temperature parameter. When the aforementioned difference is less than the second preset difference, it indicates that the target area is approaching the preset target temperature parameter. At this point, the heating module power can be reduced to maintain temperature stability and reduce energy consumption. The second preset difference can be predetermined based on temperature control accuracy, allowable temperature fluctuation range, and the need to prevent temperature overshoot. Simultaneously, the aforementioned first preset difference is greater than the aforementioned second preset difference. This allows for tiered control: high-power heating when the temperature difference is large, reduced power when the temperature difference decreases, and low-power maintenance when approaching the target temperature, thus balancing anti-condensation effect, temperature control stability, and energy consumption control.
[0048] In some exemplary embodiments, the preset target temperature parameter is determined based on the temperature at which condensation is unlikely to occur in the target area. For example, the preset target temperature parameter can be 30°C. The current temperature parameter of the target area is obtained, and the difference between the preset target temperature parameter and the current temperature parameter is calculated. For example, when the current temperature parameter of the target area is 25°C, the difference between the preset target temperature parameter and the current temperature parameter is 5°C. At this time, it indicates that the current temperature of the target area is significantly lower than the preset target temperature parameter, and the target area has a high risk of condensation. The bearing controller controls the target heating module to operate at a first power. The first power can be 100% of the rated power of the target heating module to rapidly heat up the target area. When the current temperature parameter of the target area gradually rises to between 27°C and 29°C, the difference between the preset target temperature parameter and the current temperature parameter is less than 5°C and greater than or equal to 1°C. At this time, the target area has not yet reached the preset target temperature parameter, but the risk of condensation has been reduced, and the target heating module is controlled to operate at a second power. The second power can be 50% of the rated power of the target heating module. In this stage, a PID (Proportional-Integral-Derivative Control) algorithm is used to dynamically adjust the output power of the target heating module. This ensures that the output power gradually decreases as the temperature approaches the preset target temperature parameter, thus preventing temperature overshoot caused by continuous high-power heating. When the current temperature parameter of the target area rises above 29°C, the difference between the preset target temperature parameter and the current temperature parameter is less than 1°C, indicating that the target area has approached the preset target temperature parameter. At this point, the target heating module is controlled to operate at a third power. This third power can be 20% of the rated power of the target heating module to maintain a stable temperature in the target area and prevent the temperature from dropping again, which could lead to condensation. In other words, in this embodiment, the first preset difference can be 5°C, the second preset difference can be 1°C, the first power can be 100% of the rated power, the second power can be 50% of the rated power, and the third power can be 20% of the rated power. By using the aforementioned graded power control and combining it with a PID algorithm to dynamically adjust the output power of the target heating module, the temperature can be rapidly increased when the temperature difference is large, and the heating power can be reduced when the temperature approaches the preset target temperature parameter, thereby avoiding temperature overshoot and keeping the temperature of the target area stable, reducing the risk of condensation formation.
[0049] In some exemplary embodiments of this application, the control method further includes: in the event that the acquisition of the environmental parameters fails, controlling the operation of the heating module according to a preset control strategy, wherein the preset control strategy includes controlling the heating module to turn on for a first preset duration and then controlling the heating module to turn off for a second preset duration within each preset control cycle, wherein the first preset duration is less than the second preset duration.
[0050] In the above embodiments, when environmental parameters fail to be acquired, the heating module is periodically turned on and off by a preset control strategy. This can maintain a certain anti-condensation heating capacity even when the risk of condensation cannot be accurately determined, thus avoiding the generation of condensate due to the complete shutdown of the heating module caused by sensor failure or data acquisition failure. At the same time, since the first preset duration is shorter than the second preset duration, the on-time of the heating module is shorter than the off-time, which can reduce the risk of overheating and energy consumption caused by continuous heating, and improve the safety and reliability of the control method.
[0051] In some embodiments, if environmental parameters of a preset area cannot be obtained normally during the execution of the control method, it indicates that there may be an anomaly in the data acquisition process used to detect temperature and humidity parameters. For example, the environmental detection module may experience communication interruption, loss of detection signals, or data that cannot be recognized by the bearing controller. In this case, if the heating module is stopped directly, the preset area may continue to cool down and generate condensation in an unmonitored state; if the heating module is continuously controlled to run, it may cause local overheating or increased energy consumption. Therefore, in the case of failure to acquire environmental parameters, the judgment can no longer be based on real-time environmental parameters, but the operation of the heating module can be controlled according to a preset control strategy. The preset control strategy can be a periodic start-stop control strategy, that is, in each preset control cycle, the heating module is first controlled to be turned on for a first preset duration, so that the heating module heats the corresponding area for a certain period of time; after the first preset duration ends, the heating module is controlled to be turned off for a second preset duration to avoid the heating module working continuously for a long time. The first preset duration is shorter than the second preset duration. That is, when environmental parameters cannot be obtained normally, the heating module's on time is shorter than its off time, so that the heating module operates intermittently in a more conservative manner. This not only maintains a certain level of anti-condensation capability when an anomaly is detected, reducing the risk of condensation, but also avoids overheating or excessive energy consumption caused by the heating module being continuously turned on, thus improving the safety and reliability of the control method.
[0052] In one alternative embodiment, the control method further includes: acquiring the radiator temperature in real time; and controlling the heating module to shut down when the radiator temperature is higher than a preset radiator temperature.
[0053] In the above embodiments, by acquiring the radiator temperature in real time and controlling the heating module to shut down when the radiator temperature exceeds the preset radiator temperature, over-temperature protection of the radiator can be provided during the heating process. This avoids the radiator temperature from becoming too high due to continuous operation of the heating module, thereby reducing the risk of component damage, local overheating, and safety failures, and improving the safety and reliability of the anti-condensation control method.
[0054] Specifically, the radiator is used to transfer the heat generated by the heating module to the corresponding preset area to increase the temperature of the preset area.
[0055] Embodiments of this application also provide a compressor anti-condensation control device for any of the above-described compressor anti-condensation control methods, the control device comprising:
[0056] The bearing controller is located in the compressor housing;
[0057] A heat dissipation component is thermally connected to the bearing controller, and the heat dissipation component includes multiple preset areas;
[0058] Specifically, a thermally conductive connection refers to the ability to form a heat transfer path between the bearing controller and the heat dissipation component. This can be achieved through direct contact, or by using thermal pads, thermal grease, or fasteners. Thus, the heat generated by the bearing controller during operation can be transferred to the heat dissipation component. The heat dissipation component includes multiple preset areas. These preset areas are areas on the heat dissipation component that require condensation risk monitoring and temperature regulation. Different preset areas correspond to different locations on the heat dissipation component. When the compressor is running, the temperature and humidity of different preset areas may vary; therefore, by setting multiple preset areas, the condensation risk at different locations can be monitored separately.
[0059] Multiple heating modules are disposed in multiple preset areas and are electrically connected to the bearing controller;
[0060] Multiple environmental detection modules are provided, and each of the preset areas is equipped with at least one of the environmental detection modules to monitor the environmental parameters of the preset area. The environmental detection modules are communicatively connected to the bearing controller so that the bearing controller controls the operation of the corresponding heating module according to the environmental parameters.
[0061] In the above embodiments, by setting environmental detection modules in multiple preset areas of the heat dissipation component, the temperature and humidity parameters of each preset area can be monitored in real time, thereby determining whether there is a risk of condensation in the corresponding area. By setting heating modules in the preset areas and electrically connecting the heating modules to the bearing controller, the bearing controller can control the operation of the corresponding heating modules according to the environmental parameters, and provide targeted heating to areas with a risk of condensation. This reduces the risk of condensate formation in the compressor controller installation environment, decreases the possibility of condensate corroding or damaging the bearing controller circuitry, and improves the safety and reliability of compressor operation.
[0062] In some embodiments, the heat dissipation component can be a heat sink. As a component of the bearing controller, the heat dissipation component is used to conduct and dissipate the heat generated during the operation of the bearing controller. Specifically, the heat dissipation component can be closely fitted to the heat-generating parts of the electronic devices in the bearing controller, so that the heat generated by the electronic devices can be quickly transferred to the heat dissipation component, thereby improving the heat dissipation efficiency of the bearing controller.
[0063] It should be noted that the heat dissipation component and the bearing controller can function as a single unit, with the heat dissipation component working in conjunction with the bearing controller to achieve heat dissipation and temperature regulation. However, structurally, the heat dissipation component can be detachably connected to the bearing controller. For example, the heat dissipation component can be installed on the bearing controller using screws, snap-fit structures, press-fit structures, or other detachable connection methods to facilitate subsequent maintenance, replacement, or assembly.
[0064] In some embodiments, the heat dissipation component can be extended according to the location of the low-temperature region in the compressor. That is, the extension direction and length of the heat dissipation component can be set according to the location on the compressor housing that is prone to condensation. When a certain area is prone to forming a low-temperature region due to compressor operation, the heat dissipation component can be extended to or near the low-temperature region to conduct the heat generated by the bearing controller to that region, thereby increasing the temperature of that region and reducing the risk of condensation formation.
[0065] Furthermore, in some embodiments, the overall volume or material usage of the heat dissipation component can remain substantially constant. In this case, to increase the extended coverage area of the heat dissipation component over low-temperature regions, the thickness of at least a portion of the heat dissipation component can be reduced accordingly. That is, with a fixed material usage, the heat dissipation component achieves a larger coverage area by reducing its thickness, enabling it to cover or approach more areas prone to condensation. Thus, without significantly increasing material usage and structural weight, the thermal conductivity coverage of the heat dissipation component over low-temperature regions can be improved, thereby enhancing the anti-condensation effect.
[0066] In one exemplary embodiment, such as Figure 2 As shown, the compressor anti-condensation control device includes a bearing controller 100, a compressor base 200, a heat dissipation component, a heating module 400, and an environmental detection module.
[0067] The bearing controller 100 is mounted on the compressor base 200. A heat dissipation component is thermally connected to the bearing controller 100 so that the heat generated during the operation of the bearing controller 100 can be transferred to the heat dissipation component. The heat dissipation component can be mounted on the compressor base 200 or in thermal contact with the compressor base 200.
[0068] The heat dissipation component includes multiple preset areas. These preset areas can be regions on the heat dissipation component that are susceptible to condensation risks due to the operating conditions of the compressor. For example, the heat dissipation component includes a first preset area 310, a second preset area 320, a third preset area 330, and a fourth preset area 340. Each preset area is located at a different position on the heat dissipation component to monitor the condensation risk in different areas of the heat dissipation component.
[0069] The heating module 400 is disposed in a preset area, or in a location capable of heating the preset area. Specifically, the heating module 400 can be disposed corresponding to the second preset area 320 or the fourth preset area 340. When there is a risk of condensation in the second preset area 320 or the fourth preset area 340, the bearing controller 100 can control the corresponding heating module 400 to operate, thereby increasing the temperature of the corresponding preset area and reducing the risk of condensation formation.
[0070] The environmental detection module includes multiple environmental detection components, each positioned within a corresponding preset area. For example, the module may include a first environmental detection component 510, a second environmental detection component 520, a third environmental detection component 530, a fourth environmental detection component 540, and a fifth environmental detection component 550. The first environmental detection component 510 is positioned in the overlapping area of the first preset area 310 and the fourth preset area 340; the second environmental detection component 520 is positioned in the overlapping area of the first preset area 310 and the second preset area 320; the third environmental detection component 530 is positioned in the overlapping area of the second preset area 320 and the third preset area 330; the fourth environmental detection component 540 is positioned in the overlapping area of the fourth preset area 340 and the third preset area 330; and the fifth environmental detection component 550 is located on the bearing controller. Each environmental detection component includes an integrated temperature and humidity sensor. These components are used to detect environmental parameters within their respective preset areas, including temperature and humidity parameters.
[0071] Multiple environmental sensors are communicatively connected to the bearing controller 100 to send detected environmental parameters to it. Based on the environmental parameters sent by each sensor, the bearing controller 100 determines the target area with a risk of condensation and controls the operation of the heating module 400 corresponding to that target area. The heating module 400 is placed in the second preset area 320 and the fourth preset area 340, or it can be placed in the first preset area 310 and the third preset area 330. This allows for zoned detection and zoned heating control of different locations on the heat dissipation components, improving the targeting of anti-condensation control and reducing the risk of corrosion or damage to the bearing controller 100 caused by condensate.
[0072] It should be noted that the above-mentioned settings of the first preset area, the second preset area, the third preset area, the fourth preset area, the heating module, and the environmental detection components are only used to illustrate the detection and heating control methods of different areas on the heat dissipation component, and are not intended to limit the specific number and specific location of the preset areas, the heating module, and the environmental detection module in this application.
[0073] In other embodiments, the number of preset areas can be adjusted according to the shape of the heat dissipation component, the structure of the compressor base, and the distribution of the actual condensation risk area; environmental detection components can also be set at the corners, edges, middle areas, or other locations where environmental parameters need to be detected on the heat dissipation component. The heating module can be set in any preset area, between adjacent preset areas, or at a location capable of heating one or more preset areas.
[0074] In other words, as long as the environmental detection module can detect the environmental parameters of the corresponding preset area, and the heating module can heat the target area with condensation risk when it is running, it falls under the setting method described above in this application.
[0075] In some exemplary embodiments, the heating module includes an electromagnetic induction coil and a thermally conductive metal sheet.
[0076] In the above embodiments, the electromagnetic induction coil and the heat-conducting metal sheet can generate an alternating magnetic field using the electromagnetic induction coil, causing the heat-conducting metal sheet to generate eddy current heat, and then transfer the heat to the corresponding preset area through the heat-conducting metal sheet, thereby achieving rapid and directional heating of areas with condensation risk, improving the anti-condensation response speed, and reducing the risk of condensate generation.
[0077] Embodiments of this application also provide a compressor, including any of the above-described compressor anti-condensation control devices.
[0078] The above embodiments can integrate the anti-condensation detection and heating control structure into the compressor, enabling the compressor to monitor and heat the condensation risk areas in the controller installation environment during operation. This reduces the risk of condensation caused by local low temperatures during compressor operation, reduces the possibility of condensation causing corrosion or damage to the bearing controller circuit, and improves the stability and reliability of the compressor as a whole.
[0079] It should be noted that this application does not limit the specific type of compressor. The compressor can be a magnetic levitation compressor or other types of compressors, as long as the compressor has a controller installation area where condensation is likely to occur due to localized low temperature, the anti-condensation control method and control device provided in this application can be applied.
[0080] In some embodiments, the compressor is a magnetic levitation compressor. The magnetic levitation compressor can support the rotor using magnetic bearings, and a bearing controller is used to control the magnetic bearings. Since the bearing controller is typically located on or near the compressor mounting base, the localized low temperatures generated during compressor operation may pose a condensation risk to the bearing controller's installation environment. Therefore, the control method of this application can be used to detect environmental parameters in multiple preset areas and control the operation of the heating module based on the detection results to reduce the risk of condensate generation.
[0081] Figure 3 A schematic diagram of the compressor provided in this embodiment is shown. The compressor includes a compressor base 200 and a compressor sealing cover 600, with the compressor base 200 disposed on one side of the compressor sealing cover 600. The compressor base 200 is used to mount the bearing controller 100. The compressor also includes an intake port 700 and an exhaust port 800, which are respectively disposed on opposite sides of the compressor. The intake port 700 is used to supply gas into the compressor, and the exhaust port 800 is used to supply compressed gas to exit the compressor. During compressor operation, the flow of refrigerant inside the compressor will lower the temperature of the compressor base 200 and its surrounding metal structure. Since the bearing controller 100 is located at the compressor base 200, the installation environment of the bearing controller 100 is easily affected by the low temperature of the compressor base 200. When moisture in the outside air comes into contact with the low-temperature area around the compressor base 200 or the bearing controller 100, condensation is easily generated in that area. Condensate may adhere to the compressor housing 200, the casing of the bearing controller 100, the heat dissipation structure, or the circuit area near the bearing controller 100, leading to circuit corrosion, decreased insulation performance, or even short circuits. Therefore, this application detects environmental parameters in a preset area of the bearing controller 100 installation environment and controls the operation of the heating module based on the detection results to increase the temperature of areas with condensation risk, thereby reducing the risk of condensate formation.
[0082] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the compressor anti-condensation control method of this application will be described in detail below with reference to specific embodiments.
[0083] This embodiment relates to a specific control method for preventing condensation in a compressor, such as... Figure 4 As shown, it includes the following steps:
[0084] Step S1: Obtain environmental parameters for multiple preset areas;
[0085] Specifically, environmental monitoring modules positioned around the compressor housing, radiator, and bearing controller acquire environmental parameters for multiple preset areas. These parameters include temperature and humidity. The environmental monitoring modules can include temperature and humidity sensors; for example, the temperature sensor can be a PT100 platinum resistance thermometer, and the humidity sensor can be a capacitive humidity probe. The environmental monitoring modules can collect environmental parameters at a preset sampling frequency, such as once per second, so that the bearing controller can promptly obtain information about environmental changes in each preset area.
[0086] Step S2: Determine the target area based on environmental parameters;
[0087] Specifically, after acquiring temperature and humidity parameters for multiple preset areas, the system determines whether each preset area has a condensation risk. When the temperature parameter of a preset area is lower than the preset temperature value, or the humidity parameter of the preset area is higher than the preset humidity value, it indicates that the preset area is prone to condensation, and the bearing controller identifies this preset area as the target area. The target area is the area where there is a condensation risk and anti-condensation heating control is required.
[0088] Step S3: Determine the target heating module based on the target area;
[0089] Specifically, based on the preset correspondence between target areas and heating modules, the target heating module corresponding to the target area is determined. The preset correspondence represents the relationship between each preset area and the heating module capable of heating that preset area.
[0090] Step S4: Control the operation of the target heating module;
[0091] Specifically, the target heating module is controlled to operate in order to heat the target area. The target heating module may include an electromagnetic induction coil and a heat-conducting metal sheet. The electromagnetic induction coil may be placed inside the cavity of the heat sink, and the heat-conducting metal sheet may be attached to the surface of the heat sink. When the target heating module is running, the electromagnetic induction coil generates an alternating magnetic field, which causes eddy currents in the heat-conducting metal sheet and transfers the heat to the heat sink and the corresponding target area, thereby increasing the temperature of the target area.
[0092] Step S5: Adjust the output power of the target heating module according to the temperature difference;
[0093] Specifically, the difference between the preset target temperature parameter and the temperature parameter of the target area is obtained, and the output power of the target heating module is adjusted according to this difference. For example, when the difference between the preset target temperature parameter and the temperature parameter of the target area is 5°C, the bearing controller can control the target heating module to operate at 100% of its rated power to rapidly heat up the target area. As the temperature of the target area gradually approaches the preset target temperature parameter, the bearing controller can use a PID algorithm to dynamically adjust the output power of the target heating module, gradually reducing the output power of the target heating module, for example, to 20% of the rated power, thereby avoiding temperature overshoot and maintaining a stable temperature in the target area.
[0094] Step S6: Implement radiator over-temperature protection;
[0095] Specifically, the radiator temperature is acquired in real time during the operation of the target heating module. When the radiator temperature exceeds the preset radiator temperature, it indicates that the radiator may be at risk of overheating. The bearing controller then controls the target heating module to shut down or cuts off its power supply to prevent the heating module from continuing to operate and causing the radiator to overheat, thereby improving the safety of the control method.
[0096] Furthermore, when acquiring environmental parameters fails, or when environmental parameters exceed a preset reasonable range, or when sensor signals are interrupted, the heating module is controlled to operate according to a preset control strategy. For example, the bearing controller can control the heating module to start and stop according to a preset control cycle. Within each preset control cycle, the heating module is first controlled to be on for a first preset duration, and then controlled to be off for a second preset duration, with the first preset duration being shorter than the second preset duration. Thus, even when environmental parameters cannot be acquired normally, a certain level of anti-condensation capability can still be maintained, while preventing the heating module from running continuously for extended periods, thus avoiding overheating or excessive energy consumption.
[0097] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
[0098] This invention provides a computer-readable storage medium including a stored program, wherein, when the program is executed, it controls the device containing the computer-readable storage medium to perform the compressor anti-condensation control method.
[0099] Specifically, the compressor anti-condensation control methods include:
[0100] Step S101: Obtain environmental parameters of multiple preset areas in the compressor, including temperature and humidity parameters.
[0101] Specifically, multiple preset zones are areas within the compressor that are pre-defined and require condensation risk monitoring. Temperature parameters characterize the hot or cold state of the corresponding preset zone, while humidity parameters characterize the moisture content in the air of the corresponding preset zone. By simultaneously acquiring both temperature and humidity parameters, it is possible to more accurately reflect whether each preset zone possesses the environmental conditions for condensation formation.
[0102] Step S102: Determine the target area based on the above environmental parameters. The target area is an area with a risk of condensation.
[0103] Specifically, after obtaining the environmental parameters of multiple preset areas, the system determines whether each preset area is prone to condensation based on the temperature and humidity parameters of each preset area, and identifies the preset areas with condensation risk as target areas.
[0104] Step S103: Control the heating module located in the corresponding preset area to operate according to the target area.
[0105] Specifically, after determining the target area, the heating module corresponding to the target area is controlled to operate, so that the heating module heats the corresponding preset area.
[0106] Optionally, determining the target area based on the above environmental parameters includes: determining the preset area where the temperature parameter is less than a preset temperature value as the target area, or determining the preset area where the humidity parameter is greater than a preset humidity value as the target area.
[0107] Optionally, controlling the operation of the heating module located in the corresponding preset area according to the target area includes: determining the target heating module corresponding to the target area according to the preset correspondence between the target area and the heating module; and controlling the operation of the target heating module.
[0108] Optionally, controlling the operation of the target heating module includes: acquiring the difference between a preset target temperature parameter and the temperature parameter of the target area; if the difference is greater than or equal to a first preset difference, controlling the target heating module to operate at a first power; if the difference is less than the first preset difference but greater than or equal to a second preset difference, controlling the target heating module to operate at a second power, wherein the first preset difference is greater than the second preset difference and the first power is greater than the second power; and if the difference is less than the second preset difference, controlling the target heating module to operate at a third power, wherein the third power is less than the second power.
[0109] Optionally, the above control method further includes: in the event that the acquisition of the above environmental parameters fails, controlling the operation of the heating module according to a preset control strategy, wherein the preset control strategy includes controlling the heating module to turn on for a first preset duration and then controlling the heating module to turn off for a second preset duration within each preset control cycle, wherein the first preset duration is less than the second preset duration.
[0110] Optionally, the above control method further includes: acquiring the radiator temperature in real time; and controlling the heating module to shut down when the radiator temperature is higher than the preset radiator temperature.
