Thirdly, the coordinated optimization of the volume configuration and the filtering performance in the running process of the collector system, the volume of the collection tank and the configuration of the filter plate are usually determined independently in the traditional design, lacking systematic analysis of the matching relationship between the two, resulting in the incoordination between the filtering effect and the collection capacity, the present application establishes the accurate constraint relationship that the effective filtering area of the filter plate and the internal volume of the collection tank are within the range of 0.7 to 0.9, and adopts a double-layer game model to coordinate the balance relationship between the minimum total energy consumption and the maximum filtering purification effect, realizes the collaborative solution of the upper energy consumption control model and the lower filtering optimization model through the coupling term of filter pressure drop loss, ensures the optimal matching of the collection volume and the filtering performance, and realizes the significant improvement of the overall performance of the system.

[0048] In order to better understand and implement the present application, the following provides an embodiment 2 of a specific application scenario of the present application: a technical team undertakes the condensate water treatment optimization reconstruction project of a ground source heat pump system of an office building. The original ground source heat pump system of the building has been running for many years, and the condensate discharge collection system has the technical problems of unreasonable volume design, high energy consumption, frequent filter plate replacement, etc. The original system adopts fixed volume design, the volume of the collection tank 1 is 50L, an ordinary motor 6 with a power of 15W is configured, a manual cover 10 opening and closing mode is adopted, and the filter plate 18 replacement needs to be stopped and disassembled with bolts, the maintenance period is short and the operation is complex.

[0049] The technical team first conducted an in-depth investigation of the original system, and through 7 days of continuous data collection, obtained operating parameters under different working conditions. The ambient temperature ranged from 12°C to 35°C, the refrigeration load ranged from 45% to 95% of the rated load, and the relative humidity ranged from 40% to 85%.

After model verification, the prediction accuracy reached 88%, providing a reliable basis for subsequent design.

[0050] During the volume design phase, the technical team used the volume balance equation for optimization calculation. According to the peak value of the instantaneous flow of condensate obtained from the prediction model, which was 18.5 L / h, considering the storage safety factor of 1.8, the drainage cycle interval of 8 hours, the temperature fluctuation coefficient of 1.1, and the humidity correction factor of 1.05, the optimal internal volume of collection tank 1 was calculated to be 43 L. Compared with the original 50 L volume, the new design volume was reduced by 14%, which not only met the storage requirements but also avoided overdesign.

[0051] In the motor 6 parameter optimization design, the technical team calculated the torque requirement of the motor 6 to be 1.2 N·m based on the new design of the cover plate 10 weight of 8.5 kg, the opening and closing resistance coefficient of 0.18, the screw pitch of 3 mm, the transmission efficiency of 0.92, and the safety margin of 1.5. Combined with the screw 4 speed control at 30 r / min, the power requirement of the motor 6 was determined to be 13 W, which was reduced by 13% compared with the original 15 W power.

[0052] In the process of double-layer game model optimization, the technical team first established the upper-layer energy consumption minimization objective function, considering factors such as motor 6 power consumption, fluid resistance loss, and standby energy consumption. The running time factor was set to 0.6, the filter plate 18 pressure drop loss was determined through experiment to be 350 Pa, the fluid flow was converted to , and the standby energy consumption was 3.5 W. In the lower-layer filtration effect maximization objective function, the pollutant removal rate target was set to 0.85, the flow velocity distribution uniformity was obtained through flow field simulation analysis to be 0.92, and the pressure drop weight coefficient was set to . Through Nash equilibrium solution and Pareto optimal analysis, the best parameter combination was determined.

[0053] In the filter plate 18 design optimization, the technical team determined the effective filtration area of the filter plate 18 to be 35 , the area ratio control is 0.81, which meets the design requirement of 0.7 to 0.9. The filter plate 18 is made of stainless steel mesh with a pore size of 120 μm and a thickness of 2.5 mm. The inner diameter of the storage groove 15 is designed to be 12.2 mm, and the outer diameter of the circular shaft 16 is designed to be 12.0 mm, with a matching gap control of 0.2 mm, ensuring the smoothness of quick disassembly and connection stability.

[0054] In the automatic opening and closing system design, the technical team uses a stepper motor 6 to drive a lead screw 4 transmission mechanism to achieve precise control of the cover plate 10. The length of the strip groove 3 is designed to be 240 mm, covering 80% of the height of the collection box 1. The sliding sleeve 5 has a moving stroke of 220 mm in the strip groove 3, ensuring that the cover plate 10 covers 98% of the opening area of the collection box 1 when fully opened. The sliding accuracy of the connecting plate 8 in the sliding groove 7 is controlled within ±0.3 mm, and the circular rod 12 provides stable guiding support in the vertical groove 11.

[0055] In the system integration and debugging stage, the technical team tests all functions comprehensively. The motor 6 speed is adjusted to 28 r / min, the cover plate 10 opening time is controlled to 45 seconds, and the closing time is controlled to 42 seconds, meeting the design requirements. By injecting test water flow through the water inlet pipe 19, the flow rate is controlled at 120% of the design flow rate to test the system's processing capacity. In the filter plate 18 efficiency test, the water turbidity is 85 NTU, and the effluent turbidity is 12 NTU, with a filtration efficiency of 85.9%, exceeding the design target.

[0056] The comparison of system performance parameters as shown in Table 1 shows the difference before and after optimization: Table 1 Comparison of system performance parameters

[0057] The test data in the running effect verification stage is shown in Table 2: Table 2 Running effect verification data table

[0058] The long-term running monitoring results are shown in Table 3: Table 3 Long-term running monitoring results table

[0059] After 6 months of continuous operation verification, the technical team conducted a comprehensive evaluation of the system performance. The total energy consumption of the system is stable at below 16.7 W, which is 12% lower than the original system. The filtration efficiency is always maintained above 84%, meeting the condensate water purification requirements. The automatic opening and closing function runs stably, with a failure rate of below 2%. The filter plate 18 quick disassembly and assembly function significantly improves the maintenance efficiency, with a single replacement time reduced from 25 minutes to 22 minutes, and the work intensity of maintenance personnel is significantly reduced.

[0060] The optimization effect of the double-layer game model is fully verified in actual operation. The upper layer energy consumption minimization objective realizes reasonable allocation of energy consumption of each component of the system, the motor 6 power consumption, fluid resistance loss and standby energy consumption account for 50%, 35% and 15% of the total energy consumption respectively, forming a balanced energy consumption structure. The lower layer filtration effect maximization objective realizes the best balance between filtration performance and flow resistance by optimizing the filter plate 18 structure parameters and flow field distribution, and controls the pressure drop loss in a reasonable range while ensuring high filtration efficiency.

[0061] The technical progress brought by the present application relative to the traditional means mainly lies in the scientificity of system design and the intelligentization of operation control. The traditional condensate water collector adopts an empirical design method, and the volume and power configuration often have problems of overdesign or underdesign, while the present application realizes accurate calculation and optimal configuration of parameters by establishing a mathematical model. The manual operation mode of the traditional system not only increases labor cost, but also easily leads to system failure due to improper operation, while the automatic start-stop control system of the present application realizes unattended operation through precise mechatronic design. The traditional filter plate replacement requires complex operations such as bolt disassembly, and the maintenance efficiency is low, while the quick disassembly and assembly technology of the present application realizes convenient replacement of the filter plate through precise fit design. The traditional single-objective optimization method cannot balance the relationship between energy consumption and filtration effect, while the double-layer game model of the present application realizes global optimization of system performance through multi-objective coordinated optimization, fundamentally solving the technical problem of one-sidedness in the traditional method.

[0062] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
