摘　　要：作者提出的新风直接供冷空调系统的最佳形式,对3种可能方案进行分析并做深入的讨论.确定系统的最佳形式就是系统的设计与运行优化组合的问题.而从节能的角度进行系统的优化,则是通过解决函数寻优问题,使运行能耗为最小.以设计优化与运行优化相结合的思想,建立了空调系统的风机能耗优化模型.该模型以供冷期能耗最小为目标函数,以系统的运行风量作为供冷期所需风量,以各子系统风量不大于其最大风量为约束条件,采用遗传算法进行系统的优化,得到了系统的最优设计与运行方案.In order to find the best form of outdoor air cooling system, three projects have been taken for further discussion. Determination of the best form means the optimal combination of the design and operation of systems. The optimization of systems, from the point of energy efficiency view, is to find the minimum energy consumption in operation by means of solving the problem of function optimization. An optimization model of energy consumption of fans has been developed according to the thought of integration of design and operation optimizations. It takes the minimum energy consumption in cooling period as object function, and volume sum of the subsystems as air volume demand in the same period. The restricting condition stands upon that each volume should be less than its design. Genetic algorithm is used for the system optimization in this paper,and the best design and operation is obtained.
