四家制造商提供了实验室气流和功率数据，作为35台多速风机盘管（带永久分裂电容器电机）的外部静压函数。这些数据用于开发风机盘管机组的简化性能模型，可用于构建模拟程序，以估计风机盘管机组的年度能源性能。风机盘管机组的风机电机尺寸范围为0.033至0.75马力（25至560瓦），最大气流范围为242至2646立方英尺/分钟（0.11至1.25立方米/秒）。基本模型包括一组简单的回归，将风扇电机功率与风扇气流联系起来。对整个气流范围进行建模需要二次多项式。然后将这些机组分解为风扇电机小于0.25马力（187瓦）的小型机组和风扇电机大于等于0.25马力（187瓦）的大型机组。较小单位的风扇效能值平均为0。 269 W/ft3/min（570 W/m3/s），而大型机组的平均功率为0.486 W/ft3/min（1030 W/m3/s）。还开发了一个程序，用于估算多速永久分裂电容式风机盘管机组部分负载运行时的气流和功率。引用:佛罗里达州奥兰多2020年冬季会议技术论文

Four manufacturers provided laboratory airflow andpower data as a function of external static pressure for over 35multi-speed fan-coil units with permanent split capacitormotors. These data were used to develop simplified performancemodels of fan-coil units that could be used in building simulationprograms to estimate the annual energy performance of fan-coilunits. The fan-coil units had fan motors ranging in size from0.033 to 0.75 hp (25 to 560 W) and maximum airflows thatranged from 242 to 2646 ft3/min (0.11 to 1.25 m3/s). The basicmodel consisted of a simple set of regressions relating fan motorpower to the fan airflow. Modeling the whole range of airflowsrequired a second degree polynomial. The units were then disaggregatedinto smaller units with fan motors less than 0.25 hp(187 W) and larger units with fan motors 0.25 hp (187 W) andgreater. The smaller units had values of fan efficacy that averaged0.269 W/ft3/min (570 W/m3/s) while the large units averaged0.486 W/ft3/min (1030 W/m3/s). A procedure was alsodeveloped to estimate the airflows and powers at part load operationsfor multi-speed permanent split capacitor fan-coil units.
