Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution: A high-efficiency refrigeration room system for the tire industry includes a cooling tower 1 and a cooling tower inlet electric switch butterfly valve 6. The cooling tower inlet electric switch butterfly valve 6 controls the water intake of the cooling tower 1, accurately controls the number of cooling towers used and the water flow, reduces energy waste, and improves the effective operating energy efficiency of the system.

[0018] The overflow outlet of cooling tower 1 is equipped with a comprehensive water treatment device 7. One end of the water pipe of the comprehensive water treatment device 7 is equipped with a bypass sand filter device 8. One end of the water pipe of the bypass sand filter device 8 is equipped with a chilled water pump 31. The connection port of the chilled water pump 31 is connected to an end cap type online cleaning device 4. The end cap type online cleaning device 4 improves the self-cleaning ability of the pipeline and incorporates pipeline cleaning into the online monitoring program to ensure the efficient operation of the hydraulic system.

[0019] The outlet pipe of the end cap type online cleaning device 4 is equipped with a dual-condition centrifugal chiller 2. The dual-condition centrifugal chiller 2 provides medium-temperature water at 17-23℃ or low-temperature water at 7-12℃, reducing the total installed capacity of refrigeration, reducing energy consumption, and improving the system's operating efficiency.

[0020] The outlet pipe of the dual-condition centrifugal chiller 2 is equipped with a cooling water pump 32, and the outlet pipe of the cooling water pump 32 is equipped with an electric switch valve 5. The electric switch valve 5 controls the medium-temperature chilled water and low-temperature chilled water of the dual-condition centrifugal chiller 2 to adapt to the water temperature requirements of different processes and improve the automation and efficiency of the system.

[0021] The outlet pipe of the electric switch valve 5 is equipped with a fully automatic dosing device 10, and the outlet pipe of the fully automatic dosing device 10 is equipped with an electromagnetic water treatment device 9. Through the design of the pipeline in the machine room, the hydraulic design of the pipeline and the terminal, and the selection of pipe fittings, the hydraulic resistance of the pipeline is reduced by replacing the 90° elbow with the 45° elbow and the ordinary valve with the low resistance valve, thereby reducing the head of the chilled water pump 31 and the cooling water pump 32, reducing the power consumption of the pumps, and comprehensively using parameters such as the change of terminal pressure difference, the change of temperature difference, and the opening of the terminal valve to perform frequency conversion control of the pumps, further reducing the operating energy consumption of the pumps and improving the operating energy efficiency of the system.

[0022] The electric butterfly valve 6 for the cooling tower inlet is installed at one end of the inlet pipe of the cooling tower 1. The cooling tower 1 is calculated through CFD simulation of fluid dynamics. The variable flow nozzles are used to distribute water evenly, which expands the allowable flow range for the uniform water distribution of the cooling tower 1 from 70% to 100% to 30% to 100%. The cooling water temperature is optimized from 37-32℃ to 36-31℃, which improves the heat dissipation capacity of the cooling tower 1, reduces the number of cooling towers 1, makes reasonable space arrangement, saves equipment footprint, reduces initial investment, and improves system operating efficiency.

[0023] The dual-condition centrifugal chiller 2 includes a tank 21. Support blocks 23 are connected to the left and right ends of the tank 21. A movable roller 27 is provided at the bottom end of the support block 23. A connecting base 28 is rolledly connected to the surface of the movable roller 27. A metal frame 22 is welded to the front and rear ends of the top surface of the connecting base 28. A connecting slide rod 25 is inserted into the middle position of the metal frame 22.

[0024] Connecting sliders 24 are slidably connected to the surface of the connecting rod 25. The connecting sliders 24 are bolted to the bottom of the support block 23. There are four connecting sliders 24. Two connecting sliders 24 form a group. The two groups of connecting sliders 24 are distributed left and right. Two connecting sliders 24 on the same side are distributed on the front and rear surfaces of the support block 23.

[0025] A limiting plug 26 is inserted into the top of the connecting slider 24. The limiting plug 26 is inserted into the top of the metal frame 22. A round hole is opened at the top of the metal frame 22. The limiting plug 26 and the metal frame 22 determine the position of the connecting slider 24, which makes it convenient to adjust the position of the connecting slider 24.

[0026] The system employs an intelligent management and control platform system. Based on IoT data applications and optimized equipment, it uses an ergonomic optimization control algorithm. By leveraging equipment mechanism models, system learning, and real-time load changes, it optimizes equipment start-up strategies and parameter control, ultimately achieving a high-efficiency cooling system.

[0027] When in use, it is first applied to a high-efficiency refrigeration room system in the rubber tire industry. It mainly includes a refrigeration unit, a cooling tower 1, a chilled water pump 31, and a cooling water pump 32. The ambient temperature cooling water is transported to the condenser of the refrigeration unit through the cooling water pump 32, then enters the cooling tower 1 for cooling, and then returns to the cooling water pump 32 to form a cycle. The low temperature chilled water produced by the refrigeration unit is transported to the equipment being cooled by the chilled water pump 31, then returns to the evaporator of the refrigeration unit, and enters the chilled water pump 31 to form a cycle.

[0028] Through year-round operation control strategy simulation and energy efficiency simulation calculation, high-efficiency cooling equipment selection, variable flow system, flow balance design, and airflow organization simulation analysis are carried out to improve the combined performance of equipment such as chillers, cooling towers, and water pumps. During commissioning and operation and maintenance, through traversal optimization control algorithms, and by utilizing IoT data application services and equipment mechanism models + system learning + real-time load changes, the equipment operation strategy is optimized by comprehensively considering system load characteristics and unit performance. This achieves efficient operation of the organic combination of equipment while meeting the terminal cooling load demand, maintaining efficient automatic and intelligent control of the chiller plant, and continuously optimizing equipment start-up strategies based on actual operating conditions, ultimately realizing a high-efficiency chiller room.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
