当在EnergyPlus中使用带有永久分裂电容器电机的串联风扇供电终端单元（FPTU）对HVAC系统进行建模时，用户必须输入风扇总压升高和风扇/电机效率的值。EnergyPlus模拟中使用的通用建议风机总压力值远高于8英寸入口（203 mm）系列风机供电终端装置的测量值（Bryant和Bryant，2015）。该研究中引用的数值约为0.25英寸。w、 g.（63帕）而不是1.5-3英寸。w、 g.（374-747 Pa），如文献所示。本文介绍了验证和扩展可变风量（VAV）系列风机驱动终端装置总压升测量的制造商性能数据。对于两种最常见的串联风扇供电终端单元入口尺寸，8英寸和12英寸。（203和305 mm），发现风机总压升在0。 20-0.35英寸。w、 g.（50-87帕）。EnergyPlus五区模型用于确定在使用系列FTPU对VAV系统建模时使用“差”与“好”输入值的影响。结果表明，每年的风机和热能都会受到相当大的影响。然而，HVAC总系统能量差异非常小，建议输入和“较差”输入之间的差异不到2%。只要为模拟输入选择适当较低的风机总压升高值，就基本上可以消除带有永久分裂电容器电机的串联风机供电终端装置的风机/电机效率值。引文:ASHRAE Transactions，第123卷，pt。2.

When modeling an HVAC system using series fanpowered terminal units (FPTUs) with permanent split capacitor motors in EnergyPlus, the user must enter values for fan total pressure riseandfan/motor efficiency.Commonlyrecommended fan total pressure values for use in EnergyPlus simulations are much higher than those measured for an 8 inch inlet (203 mm) series fan-powered terminal unit (Bryant and Bryant 2015). Values cited in that study were on the order of 0.25 in. w.g. (63 Pa) and not 1.5-3 in. w.g. (374-747 Pa) as found in the literature. This paper presents manufacturers’ performance data that verify and extend variable-air-volume (VAV) series fan-powered terminal unit total pressure rise measurements. For the two most common series fan-powered terminal unit inlet sizes, 8 and 12 in. (203 and 305 mm), the fan total pressure rise was found to be in the range of 0.20-0.35 in. w.g. (50-87 Pa). An EnergyPlus five-zone model was used to determine the impact of using "poor" versus "good" input values when modeling a VAV system with series FTPUs. Results show considerable impacts in yearly fan and heating energy. However, HVAC total system energy differences are quite small, less than 2% between recommended and "poor" inputs. The value for fan/motor efficiency for a series fanpowered terminal unit with a permanent split capacitor motor could essentially be eliminated as long as an appropriately low value of fan total pressure rise is selected for the simulation inputs.
