对85台装有电子交流电机的风机盘管机组的气流和功率数据进行了评估，并利用这些数据在风机电机功率和风机气流之间建立了一个简单的风机模型。虽然45台机组的数据由五家制造商提供，但其他40台机组的数据是通过一所大学实验室的一个带有功率测量的气流室生成的。评估了垂直和水平单位。性能数据包括一系列外部静压和风扇气流设置下的风扇气流和风扇电机功率。性能数据是开发一个简单模型的基础，该模型可用于建筑模拟程序，以估算风机的年能耗- 线圈单元。对于容量小于1500 ft3/min（0.71 m3/s）的机组，开发了一条风机电机功率与气流的最佳匹配线。虽然数据中存在相当大的分散性，但该模型允许对给定气流下的功率进行简单估计。对于流量高达1500 ft3/min（0.71 m3/s）的气流，还将装有电子换向电机的风机盘管机组的风机功率与装有永久分裂电容器电机的风机盘管机组的风机功率进行了比较。与使用永久分裂电容电机的机组相比，使用电子换向电机的机组在所有气流下的风扇功率都更低。引用:2021个虚拟会议技术论文

Airflow and power data on 85 fan-coil units with electronicallycommutated motors were evaluated and used todevelop a simple fan model between fan motor power and fanairflow. While data on 45 units were provided by five manufacturers,data on the other 40 units were generated using anozzle airflow chamber with power measurements at a universitylaboratory. Both vertical and horizontal units were evaluated.Performance data included fan airflow and fan motorpower over a range of external static pressures and fan airflowsettings. The performance data served as the basis for developinga simple model that could be used in building simulationprograms to estimate the annual energy use of fan-coil units.A best-fit line of fan motor power versus airflow was developedfor units less than 1500 ft3/min (0.71 m3/s) in capacity. Whilethere was considerable scatter in the data, the model allowedfor a simple estimate of power at a given airflow. The fan powerfor fan-coil units with electronically commutated motors wasalso compared to the fan power for fan-coil units with permanentsplit capacitor motors for airflows ranging up to 1500 ft3/min (0.71 m3/s). Those with electronically commutated motorshad lower fan powers at all airflows when compared to unitswith permanent split capacitor motors.
