Description

Technical Field

[0001] This invention relates to a method for selecting air distributors for automated residential areas, which belongs to the field of ship design technology. Background Technology

[0002] The selection of air distributors during ship design requires comprehensive consideration of various performance factors such as cabin area, air volume, and noise. However, selecting a suitable air distributor model from numerous options based on cabin dimensions involves a significant amount of repetitive work for designers, which is time-consuming and labor-intensive. Therefore, this invention provides an automated method for selecting air distributors in living areas. By utilizing existing parameters from the drawings, it achieves automatic selection of air distributors, thereby improving design efficiency and reducing manpower consumption.

[0003] Traditional manual selection of air distributors involves choosing the model based solely on the room's air volume, followed by assessment of whether the selection meets the room noise limits and whether it satisfies comfort requirements, based on the designer's experience.

[0004] In reality, due to regulatory requirements, noise limits for shipboard living quarters vary depending on the type of cabin. The type of air distributor also affects the noise level of the room. Furthermore, because each air distributor covers a limited area, multiple air distributors may be needed to ensure even air distribution within the cabin. Finally, the design capacity of the air distributors must meet the airflow requirements of the cabin; if the airflow of a single air distributor is insufficient, multiple air distributors must be used for air delivery.

[0005] Considering that the larger the air volume of the air distributor, the greater its noise, manual selection requires taking into account the interaction of multiple factors, which increases the burden on personnel. Currently, air distributor selection relies entirely on manual selection by designers, which is both time-consuming and labor-intensive. Furthermore, designers need to comprehensively consider the impact of the air distributor model on multiple design parameters, and if personnel lack experience, poor selection can easily affect the cabin living experience. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a method for selecting air distributors for automated residential areas, which comprehensively considers the impact of air distributor model on cabin air distribution uniformity, personnel comfort, noise level and air distributor cost.

After incrementing the value by 1, recalculate the noise value of a single fan according to step S5. and total noise value until the total noise value The value is less than And confirm that the number of air distributors at this time is ;

[0022] S7. Price based on different models of air distributors Calculate the total price of the air distributor. ;

[0023]

[0024] S8. Compare the total price when using different air distributor models. The model with the lowest total price was selected as the air distributor model for the cabin.

[0025] Compared with existing technologies, this invention has the following advantages: This method, compared to manual selection, can comprehensively consider the impact of the air distributor model on cabin airflow uniformity, passenger comfort, noise level, and air distributor cost. This method relies on drawing data for automatic selection, saving labor costs. This method can avoid problems caused by human error during manual selection.

[0026] This method integrates key information such as cabin layout, noise limits, and air distributor model parameters. It first determines the minimum number of air distributors based on both coverage area and required airflow, then dynamically adjusts the number based on noise limits to meet comfort requirements. Finally, it selects the optimal model through cost comparison. This process comprehensively considers airflow uniformity, passenger comfort, noise control, and cost-effectiveness, achieving automation and optimization in air distributor selection, effectively improving selection efficiency and rationality.

The method requires inputting the air volume-noise curve of a single air distributor to calculate the total noise level of all air distributors in the cabin. Finally, the method selects the model with the lowest total price by comparing the minimum number of air distributors required for different models and the unit price of each air distributor.
