Description

Technical Field

[0001] The present invention relates to the technical field of condensation systems, and in particular to a shared fan control method and device based on a dual condensation system. Background Art

[0002] In the field of industrial air conditioning, especially in scenarios where low outdoor temperatures (such as below 18°C) need to be cooled, the condensing system plays a vital role. For computer room air conditioners and household air conditioners, the refrigeration system is usually simple, that is, a single refrigeration system corresponds to one or more condensing fans. In this configuration, the condensing fan speed regulator can easily adjust the fan speed according to a single condensing pressure signal to meet the cooling needs.

[0003] However, in the field of industrial air conditioning, since industrial air conditioning often needs to handle a larger cooling load, a dual refrigeration system configuration is often adopted, and the two systems may share one or more condensing fans. While this configuration improves refrigeration efficiency, it also brings new challenges to the condensing fan control system.

[0004] Specifically, the dual refrigeration system will produce two different condensing pressures when working. When designing existing condensing fan speed regulators, it is usually defaulted to adjust the fan speed according to the larger condensing pressure to prevent the condensing pressure from being too high. However, this approach has obvious problems in the scenario where the dual refrigeration system shares a condensing fan: since the dual refrigeration system is usually started one after another at a certain interval, or the second system needs to be loaded when running a single refrigeration system, it is inevitable that the condensing pressure of one system will be greater than that of the other system. In addition, test data also show that as the outdoor temperature decreases, the condensing pressure difference between the two refrigeration systems will become larger and larger. This will cause the system with lower condensing pressure to face the risk of low-pressure tripping, thereby affecting the normal operation of industrial air conditioners. It can be seen that it is particularly important to provide a method that can improve the accuracy of shared fan control for dual condensing systems. Summary of the invention

[0069] Embodiment 1

[0070] See also Figure 1 , Figure 1 : is a flow chart of a shared fan control method based on a dual condensing system disclosed in an embodiment of the present invention. Figure 1 The shared fan control method based on the dual condensing system described can be applied to large industrial air conditioning control scenarios, commercial building central air conditioning control scenarios, refrigeration / cold storage industry air conditioning control scenarios, etc., and the embodiments of the present invention do not limit this. Optionally, the method can be implemented by a shared fan control device, which can be integrated in the shared fan of the dual condensing system, or can be a local server or cloud server for processing the shared fan control process of the dual condensing system, and the embodiments of the present invention do not limit this. Figure 1 As shown, the shared fan control method based on the dual condensing system may include the following operations:

[0071] 101. Obtain target condensation pressure parameters of the dual condensation system.

[0072] In an embodiment of the present invention, the target condensing pressure parameters of the dual condensing system include condensing pressure parameters of the first condensing system and the second condensing system, and the target condensing pressure parameters can be obtained by a first condensing pressure sensor of the first condensing system and a second condensing pressure sensor of the second condensing system.

[0073] Furthermore, the fault warning and diagnosis functions can be integrated to monitor and analyze the operating status of the dual condensing system, condensing pressure parameters and control parameters of its shared fan in real time, promptly detect potential fault signs, and give corresponding warning or diagnostic information. This will help operation and maintenance personnel to take timely measures to reduce the occurrence or expansion of faults and improve the operation and maintenance efficiency of the dual condensing system and shared fan.

[0074] 102. Determine the control parameters of the shared fan of the dual condensing system according to the target condensing pressure parameters of the dual condensing system.

[0075] In the embodiment of the present invention, the shared fan may be one or more. Optionally, the control parameter of the shared fan includes at least one of a speed control parameter, a wind direction control parameter, a wind temperature control parameter and a time control parameter.

[0076] For example, after measuring the condensing pressure parameters Pc1 and Pc2 of the two condensing systems, the two condensing pressure sensors of the dual condensing system can transmit them to the common fan control device, and the common fan control device compares the sizes of Pc1 and Pc2, and then determines the control parameters of the common fan based on the comparison results to adjust the condensing pressure of the corresponding condensing system.

[0077] 103. Control the common fan according to the control parameters of the common fan so that the condensation pressure between the first condensation system and the second condensation system matches.

[0078] In an embodiment of the present invention, the condensation pressures between the first condensation system and the second condensation system are matched, that is, the condensation pressures of the two condensation systems are equal, or the condensation pressure difference between the two condensation systems is reduced to a preset pressure difference threshold.

[0079] It can be seen that the implementation of the embodiment of the present invention can intelligently determine the control parameters of the common fan according to the target condensing pressure parameters of the dual condensing system, and then control the common fan according to the control parameters to adapt the condensing pressure of the dual condensing system. In this way, the excessive difference in condensing pressure of the dual condensing system and the occurrence of low-pressure / high-pressure tripping are reduced, thereby improving the reliability and accuracy of the condensing pressure control of the dual condensing system, which is beneficial to the normal operation of the industrial air conditioner.

[0080] In an optional embodiment, the step 102 of determining the control parameters of the common fan of the dual condensing system according to the target condensing pressure parameters of the dual condensing system includes:

[0081] Determine the system parameters of the dual condensing system and the equipment parameters of the common fan of the dual condensing system;

[0082] Determine a target pressure threshold of the shared fan according to system parameters of the dual condensing system and equipment parameters of the shared fan;

[0083] The control parameters of the common fan of the dual condensing system are determined according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system.

[0084] In this optional embodiment, the system parameters may include at least one of system model parameters, system location parameters, and system usage (such as historical usage, energy consumption, etc.). Further, the device parameters may include at least one of device model parameters, device location parameters, and device usage (such as historical usage, energy consumption, etc.).

[0085] Further, the target pressure threshold (the target pressure threshold can be set in advance in the common fan control device, or determined in real time according to the system parameters of the dual condensing system and the equipment parameters of the common fan) includes a start-up pressure threshold P1, a full-speed pressure threshold P2 and a warning pressure threshold P3, wherein the start-up pressure threshold is less than the full-speed pressure threshold, and the full-speed pressure threshold is less than the warning pressure threshold, that is, P1 <P2<P3。

[0086] Furthermore, the environmental parameters of the environment in which the dual condensing system is located, such as temperature parameters, humidity parameters, pressure parameters, air density parameters, altitude parameters, etc., can be obtained, and then the target pressure threshold of the shared fan can be determined based on the system parameters of the dual condensing system and the equipment parameters of the shared fan, combined with the environmental parameters.

[0087] It can be seen that this optional embodiment can determine the target pressure threshold of the shared fan based on the system parameters of the dual condensing system and the equipment parameters of the shared fan, and then compare the target pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing system, so as to determine the control parameters of the shared fan according to the comparison results. In this way, the reliability and accuracy of determining the control parameters of the shared fan can be improved, thereby reducing the wear, fatigue, overheating and overpressure of the dual condensing system and the shared fan, thereby improving the operating stability and efficiency of the dual condensing system, thereby enhancing the user experience.

[0088] In another optional embodiment, the step 102 above determines the control parameters of the common fan of the dual condensing system according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system, including:

[0089] Determining whether the condensation pressure parameters of the first condensation system and the second condensation system are both less than a starting pressure threshold;

[0090] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both lower than the starting pressure threshold, the first target condensing system with the lowest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the first target condensing system.

[0091] In this optional embodiment, for example, when it is determined that the condensing pressure parameter Pc1 of the first condensing system is less than the condensing pressure parameter Pc2 of the second condensing system and less than the starting pressure threshold P1 of the shared fan, it indicates that the condensing pressure parameters of the two condensing systems have not reached the starting pressure threshold of the shared fan. At this time, Pc1 can be transmitted to the shared fan control device, and the control parameters of the shared fan can be determined by the shared fan control device.

[0092] It can be seen that this optional embodiment can determine the control parameters of the shared fan based on the comparison results between the starting pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing system. In this way, timely and accurate response can be made based on the actual changes in the condensing pressure, which is beneficial to improve the operational adaptability and flexibility of the dual condensing system, thereby helping to improve the overall performance and operating efficiency of the dual condensing system.

[0093] In yet another optional embodiment, the step 102 of determining the control parameter of the common fan of the dual condensing system according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system further includes:

[0094] When it is determined that only one of the first condensing system and the second condensing system has a condensing pressure parameter greater than or equal to the starting pressure threshold, the condensing system whose condensing pressure parameter is greater than or equal to the starting pressure threshold is determined as the second target condensing system;

[0095] Determining whether a condensing pressure parameter of the second target condensing system is less than a full-speed pressure threshold;

[0096] When it is determined that the condensing pressure parameter of the second target condensing system is less than the full-speed pressure threshold, the control parameters of the shared fan of the dual condensing systems are determined according to the condensing pressure parameter of the second target condensing system.

[0097] In this optional embodiment, for example, when it is determined that the condensing pressure parameter Pc1 of the first condensing system is less than the starting pressure threshold P1 of the shared fan ≤ the condensing pressure parameter Pc2 of the second condensing system is less than the full-speed pressure threshold P2 of the shared fan, it indicates that the condensing pressure parameter of the condensing system with high condensing pressure has reached the starting pressure threshold of the shared fan. At this time, Pc2 can be transmitted to the shared fan control device, and the shared fan control device determines the control parameters of the shared fan to reduce the pressure of the condensing system with high condensing pressure.

[0098] It can be seen that this optional embodiment can determine the control parameters of the shared fan based on the comparison result between the full-speed pressure threshold of the shared fan and the target condensing pressure parameter of the dual condensing system. In this way, when the condensing pressure of only one condensing system reaches the starting pressure threshold, the system can be depressurized in a targeted manner, thereby improving the operating accuracy and stability of the dual condensing system, thereby improving the overall energy efficiency of the dual condensing system and ensuring the normal operation of the dual condensing system.

[0099] In yet another optional embodiment, the step 102 of determining the control parameter of the common fan of the dual condensing system according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system further includes:

[0100] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both greater than or equal to the starting pressure threshold, it is determined whether the condensing pressure parameters of the first condensing system and the second condensing system are both less than the full-speed pressure threshold;

[0101] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both less than the full-speed pressure threshold, or only one of the first condensing system and the second condensing system is greater than or equal to the full-speed pressure threshold and less than the warning pressure threshold, a third target condensing system with the lowest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the third target condensing system.

[0102] In this optional embodiment, for example, when it is determined that the starting pressure threshold P1 of the shared fan ≤ the condensing pressure parameter Pc1 of the first condensing system < the condensing pressure parameter Pc2 of the second condensing system < the full-speed pressure threshold P2 of the shared fan, or the starting pressure threshold P1 of the shared fan ≤ the condensing pressure parameter Pc1 of the first condensing system < the full-speed pressure threshold P2 of the shared fan ≤ the condensing pressure parameter Pc2 of the second condensing system < the warning pressure threshold P3, it indicates that the condensing pressure parameters of the two condensing systems have reached the starting pressure threshold of the shared fan, and the condensing system with high condensing pressure has no risk of high-pressure tripping. At this time, Pc1 can be transmitted to the shared fan control device, and the shared fan control device determines the control parameters of the shared fan to prevent the condensing system with low condensing pressure from experiencing a situation where the pressure is getting lower and lower.

[0103] It can be seen that this optional embodiment can determine the control parameters of the shared fan based on the comparison results between the full-speed pressure threshold and the warning pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing system. In this way, the occurrence of further pressure reduction in the condensing system with too low condensing pressure can be effectively reduced, which not only improves the operating stability of the dual condensing system, but also optimizes the energy usage of large-scale air-conditioning control scenarios, ensuring that the dual condensing system can operate efficiently and safely under different condensing pressures.

[0104] In yet another optional embodiment, the step 102 of determining the control parameter of the common fan of the dual condensing system according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system further includes:

[0105] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both greater than or equal to the full-speed pressure threshold, the fourth target condensing system with the highest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the fourth target condensing system.

[0106] In this optional embodiment, for example, when it is determined that the full-speed pressure threshold value P2 of the shared fan ≤ the condensing pressure parameter Pc1 of the first condensing system < the condensing pressure parameter Pc2 of the second condensing system, it means that the condensing pressure parameters of the two condensing systems have reached the full-speed pressure threshold value of the shared fan, and the condensing system with low condensing pressure will not experience a situation where the pressure is getting lower and lower. At this time, Pc2 can be transmitted to the shared fan control device, and the shared fan control device determines the control parameters of the shared fan to dissipate heat for the condensing system with high condensing pressure.

[0107] It can be seen that this optional embodiment can determine the control parameters of the shared fan based on the comparison results between the full-speed pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing systems, so as to dissipate heat from the condensing system with high condensing pressure. In this way, when the condensing pressures of the two condensing systems reach or exceed the full-speed pressure threshold, the occurrence of overheating of the condensing system can be reduced, thereby improving the control reliability and accuracy of the shared fan, thereby reducing the occurrence of device damage.

Optionally, the method can be implemented by a shared fan control device, which can be integrated in the shared fan of the dual condensing system, or can be a local server or cloud server for processing the shared fan control process of the dual condensing system, and the embodiments of the present invention do not limit this. Figure 2 As shown, the shared fan control method based on the dual condensing system may include the following operations:

[0110] 201. Obtain target condensation pressure parameters of the dual condensation system.

[0111] 202. Determine whether a condensation pressure parameter of at least one condensation system among the first condensation system and the second condensation system is greater than or equal to a warning pressure threshold.

[0112] 203. When it is determined that the condensation pressure parameter of at least one of the first condensation system and the second condensation system is greater than or equal to the warning pressure threshold, a fifth target condensation system with the highest condensation pressure parameter is determined from the first condensation system and the second condensation system, and control parameters of the common fan of the dual condensation systems are determined based on the condensation pressure parameters of the fifth target condensation system.

[0113] In an embodiment of the present invention, for example, when it is determined that the condensing pressure parameter Pc1 of the first condensing system is less than the warning pressure threshold P3 of the shared fan ≤ the condensing pressure parameter Pc2 of the second condensing system, or the warning pressure threshold P3 of the shared fan is less than the condensing pressure parameter Pc1 of the first condensing system ≤ the condensing pressure parameter Pc2 of the second condensing system, it indicates that the condensing system with high condensing pressure may have a high-pressure trip risk. At this time, Pc2 can be transmitted to the shared fan control device, and the shared fan control device determines the control parameters of the shared fan to reduce the pressure of the condensing system with high condensing pressure and reduce the occurrence of high-pressure trips.

[0114] 204. Control the shared fan according to the control parameters of the shared fan so that the condensation pressure between the first condensation system and the second condensation system matches.

[0115] In the embodiment of the present invention, for other descriptions of step 201 and step 204, please refer to the detailed description of step 101 and step 103 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0116] It can be seen that the implementation of the embodiment of the present invention can determine the control parameters of the common fan based on the comparison result between the full-speed pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system, so as to reduce the pressure of the condensing system with high condensing pressure. In this way, when the condensing pressure of at least one condensing system exceeds the warning pressure threshold, the shared fan control device can quickly identify the condensing system with excessively high condensing pressure, thereby reducing the risk of high-pressure tripping of the condensing system, thereby further improving the operating stability of the dual condensing system.

In this way, the excessive difference in condensing pressure of the dual condensing system and the occurrence of low-pressure / high-pressure tripping are reduced, thereby improving the reliability and accuracy of the condensing pressure control of the dual condensing system, which is beneficial to the normal operation of industrial air conditioning.

[0128] In this optional embodiment, the system parameters include at least one of system model parameters, system location parameters, and system usage conditions, and the device parameters include at least one of device model parameters, device location parameters, and device usage conditions.

[0129] In this optional embodiment, optionally, the target pressure threshold includes a starting pressure threshold, a full-speed pressure threshold and a warning pressure threshold, the starting pressure threshold is less than the full-speed pressure threshold, and the full-speed pressure threshold is less than the warning pressure threshold.

[0130] It can be seen that the implementation Figure 3The described shared fan control device based on the dual condensing system can determine the target pressure threshold of the shared fan according to the system parameters of the dual condensing system and the equipment parameters of the shared fan, and then compare the target pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing system, so as to determine the control parameters of the shared fan according to the comparison results.

[0132] Determining whether the condensation pressure parameters of the first condensation system and the second condensation system are both less than a starting pressure threshold;

[0133] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both lower than the starting pressure threshold, the first target condensing system with the lowest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the first target condensing system.

[0134] It can be seen that the implementation Figure 3 The described shared fan control device based on the dual condensing system can determine the control parameters of the shared fan according to the comparison result between the starting pressure threshold of the shared fan and the target condensing pressure parameter of the dual condensing system. In this way, timely and accurate response can be made based on the actual change of the condensing pressure, which is beneficial to improve the operational adaptability and flexibility of the dual condensing system, thereby helping to improve the overall performance and operating efficiency of the dual condensing system.

[0137] Determining whether a condensing pressure parameter of the second target condensing system is less than a full-speed pressure threshold;

[0138] When it is determined that the condensing pressure parameter of the second target condensing system is less than the full-speed pressure threshold, the control parameters of the shared fan of the dual condensing systems are determined according to the condensing pressure parameter of the second target condensing system.

[0139] It can be seen that implementation Figure 3 The described shared fan control device based on a dual condensing system can determine the control parameters of the shared fan according to the comparison result between the full-speed pressure threshold of the shared fan and the target condensing pressure parameter of the dual condensing system. In this way, when the condensing pressure of only one condensing system reaches the starting pressure threshold, the system can be depressurized in a targeted manner, thereby improving the operating accuracy and stability of the dual condensing system, thereby improving the overall energy efficiency of the dual condensing system and ensuring the normal operation of the dual condensing system.

[0142] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both less than the full-speed pressure threshold, or only one of the first condensing system and the second condensing system is greater than or equal to the full-speed pressure threshold and less than the warning pressure threshold, a third target condensing system with the lowest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the third target condensing system.

[0143] It can be seen that implementation Figure 3 The described shared fan control device based on the dual condensing system can determine the control parameters of the shared fan according to the comparison result between the full-speed pressure threshold and the warning pressure threshold of the shared fan and the target condensing pressure parameters of the dual condensing system. In this way, the further pressure reduction of the condensing system with too low condensing pressure can be effectively reduced, which not only improves the operating stability of the dual condensing system, but also optimizes the energy usage of large-scale air-conditioning control scenarios, ensuring that the dual condensing system can operate efficiently and safely under different condensing pressures.

[0145] When it is determined that the condensing pressure parameters of the first condensing system and the second condensing system are both greater than or equal to the full-speed pressure threshold, the fourth target condensing system with the highest condensing pressure parameter is determined from the first condensing system and the second condensing system, and the control parameters of the common fan of the dual condensing systems are determined based on the condensing pressure parameters of the fourth target condensing system.

[0146] It can be seen that implementation Figure 3 The described shared fan control device based on a dual condensing system can determine the control parameters of the shared fan based on the comparison result between the full-speed pressure threshold of the shared fan and the target condensing pressure parameter of the dual condensing system, so as to dissipate heat from the condensing system with a high condensing pressure. In this way, when the condensing pressures of the two condensing systems reach or exceed the full-speed pressure threshold, the overheating of the condensing system can be reduced, thereby improving the control reliability and accuracy of the shared fan, thereby reducing the occurrence of damage to the device.

[0147] In yet another optional embodiment, the determination module 302 determines the control parameter of the common fan of the dual condensing system according to the target pressure threshold of the common fan and the target condensing pressure parameter of the dual condensing system, specifically including:
