[0044] Example 1

[0045] Additional aspects and advantages of embodiments of the present invention will be described in part in the following description, and will become apparent from the following description, or will be learned through practice of embodiments of the present invention. Figure 1-Figure 8 A cooling tower construction optimization method provided by an embodiment of the present invention comprises the following steps:

[0046] S1: Optimize cooling tower selection by considering on-site environmental factors.

[0047] S2: Based on the optimized cooling tower selection, design multiple cooling tower construction plans.

[0048] S3: Perform airflow organization simulation on cooling towers in multiple cooling tower construction plans to obtain cooling tower operation data for the multiple construction plans.

[0049] S4: Compare and analyze the cooling tower operation data to determine the optimal cooling tower construction plan.

[0050] S5: Based on the optimal cooling tower construction plan, a three-dimensional BIM construction model is established.

[0051] S6: Guide the on-site installation of cooling towers based on the 3D BIM construction model.

[0052] Specifically, step S1 of optimizing the cooling tower selection by considering the on-site environmental factors also includes:

[0053] Step S1-1: Determine the size of the cooling tower according to the on-site construction environment, placement space and cooling tower selection specifications.

[0054] Step S1-2: Optimize the inlet and outlet water temperatures of the cooling tower and the power consumption of the cooling tower to obtain an optimized cooling tower selection.

[0055] Due to the limited placement space of the cooling tower in the on-site environment, the obstruction of the outdoor side by the louver and perforated plate, the obstruction of the indoor side by the building body, the hot air backflow and the influence of the on-site air flow, the selection of the cooling tower needs to be optimized. In full consideration of the complex environment of the site, to ensure the normal operation of the cooling tower and meet the energy-saving requirements, the size of the cooling tower is first determined according to the requirements of the on-site construction environment, placement space and cooling tower selection specifications. The cooling tower selection specification requires that the cooling tower selection must be at least 2.3 m away from the solid wall, 1 m away from the louver wall, and the foundation height is 1.2 m. The average heat dissipation loss and treated water volume of the cooling tower are evaluated through CFD airflow organization simulation (simulating that all equipment are running in the hottest environment). It is found that the average heat dissipation loss is high, indicating that the ventilation and heat dissipation effect is poor and the treated water volume is less than 690 m³ / h, which does not meet the requirements of the host. In addition, the cooling tower motor power is 55 KW and the inlet and outlet water temperature is 37 / 32 ℃, and the power consumption is high. Therefore, the inlet and outlet water temperature of the cooling tower and the power consumption of the cooling tower need to be optimized. The embodiment of the present invention ultimately reduces the cooling tower motor power from the original 55 KW to 45 KW, and optimizes the cooling tower inlet and outlet water temperatures from the original 37 / 32 ° C to 35.5 / 30.5 ° C. Combined with the on-site environment, it just meets the requirements of the cooling tower selection specification and the placement space. The optimized cooling tower selection can better reduce the water temperature, the cooling tower operation effect is better and the power consumption is greatly reduced, which is conducive to reducing the power consumption of the equipment and improving the operating energy efficiency of the system.

[0056] Specifically, in step S2, based on the selection of cooling towers, multiple cooling tower construction plans are designed. Due to the limited placement space of the cooling tower in the on-site environment, the outdoor side is blocked by louvers and perforated plates, and the indoor side is blocked by the building body, and the air is refluxed, resulting in a certain degree of decrease in cooling capacity. Therefore, it is necessary to optimize the construction plan of the cooling tower. The embodiments of the present invention respectively use the first construction plan, the second construction plan and the third construction plan to optimize the construction of the cooling tower. The first construction plan is to arrange the cooling tower according to the original design plan after the cooling tower is optimized and selected, and the cooling tower relies on the bottom frame structure space for air intake and heat dissipation; the second construction plan is to raise the cooling tower to 2m of the frame structure on the basis of the first construction plan. The third construction plan is to add partitions and air guide tubes to the bottom frame of the cooling tower on the basis of the second construction plan.

[0057] Specifically, step S3 uses CFD technology to simulate the airflow organization of the cooling towers in the three construction schemes under multiple airflow conditions, and obtains the operating data of the cooling towers in the three construction schemes under multiple airflow conditions. The operating data includes the average heat dissipation loss and the amount of water treated of the cooling tower. The embodiment of the present invention simulates the airflow organization of the cooling towers in the three construction schemes under five airflow conditions, respectively, to evaluate five wind directions and corresponding airflow velocities, including: no wind, southeast by east (ESE, 0.5 m / s), southeast by east (ESE, 2.7 m / s), northeast by east (ENE, 0.5 m / s) and northeast by east (ENE, 2.9 m / s) conditions of ventilation, heat dissipation and cooling water volume. Specifically including:

[0058] Under windless conditions, the airflow organization of the cooling tower in each construction scheme is simulated;

[0059] Under the conditions of southeast by east wind direction and air flow velocity of 0.5 m / s, the air flow organization of the cooling tower in each construction scheme was simulated;

[0060] Under the conditions of southeast by east wind direction and air flow velocity of 2.7 m / s, the air flow organization of the cooling tower in each construction scheme was simulated;

[0061] Under the conditions of northeast by east wind direction and air flow velocity of 0.5 m / s, the air flow organization of the cooling tower in each construction scheme was simulated;

[0062] The airflow organization of the cooling tower in each construction scheme was simulated under the conditions of northeast-east wind direction and air flow velocity of 2.9 m / s.

[0063] Specifically, step S4 compares and analyzes the cooling tower operation data to determine the optimal cooling tower construction plan, which specifically includes:

[0064] Step S4-1: Compare and analyze the operating data of the cooling towers in each construction scheme under different airflow conditions to obtain the optimal operating data of the cooling towers. In this step, the values ​​of the operating data measured under different airflow conditions of the cooling towers in each construction scheme are compared with the preset values. When the measured operating data value is greater than or equal to the preset value, the cooling water volume requirement is met. The operating data that meet the cooling water volume requirement are compared to obtain the optimal operating data.

[0065] Step S4-2: Determine the optimal cooling tower construction plan corresponding to the optimal operating data according to the optimal operating data.

[0066] After the CFD airflow organization simulation, the average heat dissipation loss and water volume of the three construction schemes are compared and analyzed to reflect the ventilation and heat dissipation and cooling capacity of the cooling tower. After data analysis, it can be determined that the optimal construction scheme is obtained while ensuring the normal operation of the cooling tower. The optimal scheme of the embodiment of the present invention is the third construction scheme, that is, the cooling tower motor power is 45 KW, the inlet and outlet water temperatures are 35.5 / 30.5 ℃, the equipment is raised to 2 m of the frame structure, and partitions and air guides are added.

[0067] Specifically, step S5 establishes a three-dimensional BIM construction model based on the optimal cooling tower construction plan, and establishes a three-dimensional construction model of the cooling tower through BIM technology to guide on-site construction.

[0068] Specifically, step S6 guides the on-site installation of the cooling tower according to the three-dimensional BIM construction model. After the on-site infrastructure structure is completed and the cooling tower is qualified through on-site acceptance, the three-dimensional BIM construction model is used to guide the installation of the cooling tower.

[0069] Example 2

[0070] The embodiment of the present invention further provides a cooling tower construction optimization system, comprising:

[0071] Cooling tower selection optimization module 1 is used to optimize the cooling tower selection according to on-site environmental factors.

[0072] The construction scheme design module 2 is used to design multiple cooling tower construction schemes according to the optimized cooling tower selection.

[0073] The airflow organization simulation module 3 is used to simulate the airflow organization of the cooling towers in multiple cooling tower construction plans to obtain the cooling tower operation data of the multiple construction plans.

[0074] The data analysis module 4 is used to compare and analyze the cooling tower operation data and determine the optimal cooling tower construction plan.

[0075] The BIM modeling module 5 is used to establish a three-dimensional BIM construction model according to the optimal cooling tower construction plan.

[0076] Example 3

[0077] The working process of the present invention is described in detail below with a specific embodiment. It should be noted that this embodiment is only described as a specific embodiment, and the specific implementation is not limited to this.

[0078] The embodiment of the present invention sets 12 cooling towers and labels the 12 cooling towers. Due to the limited placement space of the cooling towers, they are blocked by louvers and perforated plates on the outdoor side and by the building body on the indoor side, which causes exhaust air to reflux, resulting in increased power consumption of the equipment. In order to improve the energy efficiency of the system, the embodiment of the present invention optimizes the selection of 12 cooling towers in full consideration of the on-site construction environment and the energy-saving requirements of the cooling towers, reduces the power of the cooling tower motor from the original 55KW to 45KW, and optimizes the inlet and outlet water temperatures of the cooling tower from the original 37 / 32 ℃ ​​to 35.5 / 30.5℃, thereby greatly reducing the power consumption of the equipment. On this basis, the embodiment of the present invention designs three cooling tower construction schemes, and uses CFD airflow organization simulation technology to evaluate the three cooling tower construction schemes. By comparing and analyzing the average heat loss and treated water volume of the cooling towers in the three construction schemes, the ventilation and heat dissipation conditions and cooling capacity of the cooling towers in the three construction schemes are evaluated. Under the premise of ensuring the normal operation of the entire system, the optimal construction scheme is determined, and finally the optimal construction scheme is modeled using BIM technology to guide the on-site construction of the cooling tower. The three cooling tower construction schemes designed in the embodiments of the present invention and the corresponding evaluation processes are as follows:

[0079] Option 1:

[0080] After determining the optimal selection of the cooling tower, the optimized cooling tower motor power is 45KW, the inlet and outlet water temperatures are 35.5 / 30.5℃, 12 cooling towers are arranged according to the original design plan and each cooling tower is numbered, and each cooling tower relies on the frame structure space at the bottom to take in air and dissipate heat. The embodiment of the present invention uses CFD airflow organization simulation technology to simulate and evaluate the cooling tower construction plan of Scheme 1 under 5 airflow conditions, where the 5 airflow conditions include 5 wind directions and corresponding airflow speeds, specifically including no wind, southeast by east (ESE, 0.5 m / s), southeast by east (ESE, 2.7 m / s), northeast by east (ENE, 0.5m / s) and northeast by east (ENE, 2.9 m / s). The evaluation results are as follows Figure 3 and Figure 6As shown, under windless conditions, the cooling capacity of each cooling tower is 512-569 m³ / h, under wind direction of southeast by east (ESE) and air flow velocity of 0.5 m / s, the cooling capacity of each cooling tower is 553-602 m³ / h; under wind direction of southeast by east (ESE) and air flow velocity of 2.7 m / s, the cooling capacity of each cooling tower is 578-635 m³ / h; under wind direction of northeast by east (ENE) and air flow velocity of 0.5 m / s, the cooling capacity of each cooling tower is 553-619 m³ / h; under wind direction of northeast by east (ENE) and air flow velocity of 2.9 m / s, the cooling capacity of each cooling tower is 594-635 m³ / h. The average heat dissipation loss of scheme 1 is calculated to be 29.47%. Under various external air flow conditions, the processing capacity of each tower type is less than 635 m³ / h, which cannot meet the cooling water demand of the host.

[0081] Option 2:

[0082] Scheme 2 is to raise the equipment foundation from 1.2m to 2m based on Scheme 1, so as to obtain a larger area exposed to fresh air. CFD airflow organization simulation technology is used to simulate and evaluate the cooling tower construction scheme of Scheme 2 under 5 airflow conditions. The evaluation results are as follows: Figure 4 and Figure 6 As shown, under windless conditions, the cooling capacity of each cooling tower is 612-655 m³ / h, and under wind direction of southeast by east (ESE) and air flow velocity of 0.5 m / s, the cooling capacity of each cooling tower is 647-698 m³ / h; under wind direction of southeast by east (ESE) and air flow velocity of 2.7 m / s, the cooling capacity of each cooling tower is 672-733 m³ / h, under wind direction of northeast by east (ENE) and air flow velocity of 0.5 m / s, the cooling capacity of each cooling tower is 638-707 m³ / h; under wind direction of northeast by east (ENE) and air flow velocity of 2.9 m / s, the cooling capacity of each cooling tower is 690-724 m³ / h. The average heat dissipation loss of Scheme 2 is calculated to be 22.31%. This scheme cannot meet the cooling water demand of the host under windless conditions. Under other air flow conditions, some cooling towers can meet the cooling water demand of the host.

[0083] Option 3:

[0084] Scheme 3 is to add partitions and air ducts above the cooling tower on the basis of Scheme 2 to improve ventilation and heat dissipation capacity and prevent air backflow. CFD airflow organization simulation technology is used to simulate and evaluate the cooling tower construction plan of Scheme 3 under 5 airflow conditions. The evaluation results are as follows: Figure 5 and Figure 6As shown, under windless conditions, the cooling capacity of each cooling tower is 690-724 m³ / h, under the condition of 0.5 m / s air flow velocity in the southeast by east (ESE), the cooling capacity of each cooling tower is 733-759 m³ / h; under the condition of 2.7 m / s air flow velocity in the southeast by east (ESE), the cooling capacity of each cooling tower is 750-784 m³ / h; under the condition of 0.5 m / s air flow velocity in the northeast by east (ENE), the cooling capacity of each cooling tower is 741-759 m³ / h; under the condition of 2.9 m / s air flow velocity in the northeast by east (ENE), the cooling capacity of each cooling tower is 767-793 m³ / h. The average heat dissipation loss of scheme three is calculated to be 12.93%, and the minimum processing capacity under various external air flow conditions is 690 m³ / h, which can meet the cooling water demand of the host.

[0085] By comparing and analyzing the evaluation results of the cooling tower construction plans of Plans 1, 2 and 3, Plan 3 was finally determined to be the optimal construction plan for the cooling tower, that is, the cooling tower motor power is 45 KW, the inlet and outlet water temperature is 35.5 / 30.5 ℃, the equipment is raised to 2 m above the frame structure, and partitions and air guides are added above the cooling tower. After determining the optimal construction plan, BIM technology was used to perform three-dimensional modeling of the cooling tower construction process to facilitate on-site installation of the cooling tower.

[0086] The embodiment of the present invention reduces the motor power of the cooling tower from the original 55 KW to 45 KW by implementing the selection optimization of the cooling tower, and optimizes the inlet and outlet water temperature from the original 37 / 32 ℃ ​​to 35.5 / 30.5 ℃, greatly reducing the power consumption of the equipment. By raising the foundation of the equipment to 2 m of the frame structure, a larger area is exposed to fresh air. By adding air guides and baffles above the cooling tower, ventilation and heat dissipation and prevention of air backflow can be facilitated. Combined with local climatic conditions, site conditions, cooling towers and surrounding environment, CFD airflow organization simulation technology is used for evaluation. When the motor power of the cooling tower is 45 KW, the inlet and outlet water temperatures are 35.5 / 30.5 ℃, the equipment is raised to 2 m of the frame structure, and baffles and air guides are added, the average heat dissipation loss is 12.93%. Under various external airflow conditions, the minimum processing capacity is 690 m³ / h, which can meet the cooling water demand of the host.
