How to use for clean roomFFUThe fan filter unit design is optimized?

1. On the basis of the theoretical formula of multi-tube high efficiency filter resistance established by experimental research, the optimal design mathematical model of this type of filter is established with the total cost of life as the objective function. Use sequence quadratic rule

2. On the basis of the theoretical formula of multi-tube high efficiency filter resistance established by experimental research, the optimal design mathematical model of this type of filter is established with the total cost of life as the objective function. The sequential quadratic programming method is used to solve this constrained optimization model, and the optimal structural design parameters of this kind of filter when the total cost of the life period is the smallest are obtained. And compared with the results obtained by minimizing resistance, it is pointed out that the optimal design based on the total life-time cost is more reasonable.


3. Multi-tube high efficiency air filter is a new structure of high efficiency air filter. In addition to the advantages of good performance and low energy consumption, its structure is simple, easy to manufacture, and low in price, so it has certain technical performance under the same technical performance. The economic advantage. The optimal design of the air filter is of great significance to give full play to its technical and economic advantages. The optimal design of the filter is generally considered to minimize the resistance under the premise of ensuring technical performance, in order to reduce energy consumption and operating costs.


4. But as far as the multi-tube high efficiency air filter is concerned, its structure and material characteristics determine that its volume and maintenance are relatively large, so the increase in its cost cannot be ignored. It can be seen that it is of practical significance to study the influence of the technical economy of the filter on the optimal design result.


In recent years, more and more engineering optimization designs have adopted the total lifetime cost index as the objective function of the optimal design mathematical model to conduct technical and economic analysis of the problem. This paper also uses this method. Based on the total resistance formula of this type of high-efficiency air filter obtained by a large number of experimental studies, a mathematical model with the minimum life-time cost is established and the problem is solved as this type ofFFUThe basis for the design of high efficiency air filters, and some practical conclusions have been obtained.
