For example, the EnergyPlus 8.7 template for fan-powered terminal
units (also called powered induction units in EnergyPlus) found in the EnergyPlus Input Output Reference (8) describes all the inputs used to model a parallel or series FPTU.
Modeling the performance of ECM and SCR parallel fan-powered terminal
units in single-duct VAV systems.
Performance of VAV series fan-powered terminal
units: Experimental results and models.
"A simplified model of the fan/motor performance of fan-powered terminal
units that use electronically commutated motors." ASHRAE Transactions 121(2):306-320.
Performance of series fan-powered terminal
units with Electronically Commutated Motors.
For example, EnergyPlus was limited to the modeling of a fixed airflow fan/motor in the fan-powered terminal
unit and did not allow modulating the terminal unit fan to meet varying zone loads.
Peng Yin: To investigate the impact of different factors, such as primary air leakage in parallel units and air filter loading, on the performance of fan-powered terminal
units, we need measured data either from field or laboratory testing.
Characterizing the performance of fixed-airflow series fan-powered terminal
units using a mass and energy balance approach.
These systems and components include fan coils, both refrigerant and electric, parallel fan-powered terminals
and small circulating pumps.
Modeling fan-powered terminal
unit fan/motor combinations controlled by silicon controlled rectifiers.
When modeling an HVAC system using series fan-powered terminal
units (FPTUs) with permanent split capacitor motors in EnergyPlus, the user must enter values for fan total pressure rise and fan/motor efficiency.
units have been a key component of many building HVAC systems over the years, as they are largely responsible for helping move air through a building to occupant spaces.
