Application of Genetic Algorithm to Optimal Design of Central Air-Conditioning Water System

Abstract

The optimal design of air-conditioning water system is an optimization problem of functions that depend on a series of nonlinear discrete multi-variables.Many traditional methods are not satisfactory when applied in this field. However, genetic algorithm (GA ) has special advantages in tackling this problem based on its inherent characteristics.Genetic algorithm (GA) is adopted and applied in the optimal design of air-conditioning water system in this study. A mathematical model and constrained conditions are put forward. This paper gives an overall introduction of basic principles of GA and analyzes the characteristics of water system, the pipe code technology, the evaluation function, crossover operator and mutation operator of GA. An optimal design program of central air-conditioning water system has been made using GA. In order to verify the effectiveness of the program, a practical project is analyzed. A comparison of GA and the traditional velocity method shows that more economical solution has been achieved by using GA. It is concluded that GA provides better optimal solutions for air-conditioning water system design.
