摘　　要：主要研究变风量(VAV)空调系统的水力特性数学模型的建立。以一个实际的压力无关型、无动力空调末端的VAV空调系统为研究对象,利用MATLAB语言编制程序,建立了系统主要部件的阻力特性数学模型。结合图论和流体管网的基本理论,运用"MKP"计算方法建立了空调风系统管网的数学模型。在此基础上搭建了可对管网进行任意工况下的水力分析的水力计算平台,并给出了一组系统仿真结果。The establishment of the math models of the hydraulic characteristic of VAV air-conditioning system is mainly studied in this paper. Taking an actual VAV air-conditioning system with Pressure-Independent and Non-Power VAV BOX as the research target, and using MATLAB program, the math models of the resistance characteristic of main components in the system are established. According to the basic theory of graph and fluid network, using the ＇MKP＇ computing method, the math model of the air-condition wind system is established. On that basis, the hydraulic calculation platform which can do the hydraulic analyzing of the pipeline network under any working condition is established and a group of the system simulation results is provided.
