摘　　要：从模块化建模的角度出发,针对在暖通空调系统中常见的单相流体网络,对一些关键部件进行合理假设、划分并建模,通过将网络节点抽象成小容积环节并建立容积模块,实现模块化建模。仿真结果表明,采用容积模块可以克服传统的迭代算法缺陷,大大减小在线计算量,高效实现动态仿真。Based on the idea of module modeling, a single-phase flow network of HVAC is decomposed into different component modules and volume modules after rational assumptions is made, and the network joints are looked as small volume unit. Simulation results show that the volume module helps to decrease online computation time and optimize module connection, and then the more efficient dynamic simulation is accomplished.
