传统的质量和能量平衡组件方法用于表征固定气流系列风机驱动终端装置的性能，以应用于建筑模拟程序。该方法包括为风扇驱动的终端装置中的部件——加热线圈、风扇/电机组合和混合器——建立相关的能量和质量平衡方程。模型开发中包括由可控硅整流器控制的永久分裂电容器电机或电子换向电机的风扇电机。本文演示了如何将永久分裂电容器和电子换向电机的风扇/电机组合性能模型纳入质量和能量平衡方法。风扇模型是根据多个风扇提供的性能数据开发的- 电力终端设备制造商。风扇/电机性能数据包括250至3500ft³/min（0.118m³/s至1.65m³/s）的风扇气流范围和0.333至1hp（248.6至745.7W）的电机尺寸范围。引用:2016年年度会议，密苏里州圣路易斯，2016年交易，第122卷。2.

A traditional mass and energy balance component approach was used to characterize the performance of fixed-airflow series fan-powered terminal units for applications in building simulation programs. The approach included developing relevant energy and mass balance equations for the components in a fan-powered terminal unit--heating coil, fan/motor combination, and mixer. Fan motors that included permanent-split-capacitor motors controlled by silicon-controlled rectifiers or electronically commutated motors were included in the model development.The paper demonstrates how to incorporate the fan/motor combination performance models for both permanent-split-capacitor and electronically commutated motors into the mass and energy balance approach. The fan models were developed from performance data that were provided by multiple fan-powered terminal unit manufacturers. The fan/motor performance data included a fan airflow range from 250 to 3500ft3/min (0.118to1.65m3/s) and a motor size range from 0.333 to 1 hp (248.6 to 745.7 W).
