Johnson Controls Parallel Fan Powered VAV terminals provide flexibility in performance ranges to meet a multitude of system design requirements.
The VAV solid state VAV fan series and parallel fan controller is in connection with at least one transformer, external VAV controller, fan, speed adjuster, reheat device, and circuit breaker for conditioning an air volume. A sensor associated with the external VAV controller constantly monitors ...

A model was also developed to quantify air leakage when the unit fan was off. In all but one of the VAV terminal units, the resulting models of airflow and power had R2 values greater than 0.90. For the exception, excessive air leakage from the unit appeared to limit the ability of ...

parallel fan powered terminal units. Each system type was operated in a simulation that varied geographic location in five regions of the United States and under several different control strategies. Results show that, depending on system loads, system control, and operational settings, the VAV ...
Modeling the Performance of ECM and SCR Parallel Fan-Powered Terminal Units in Single-Duct VAV Systems.Single duct variable air volume systems often use series and parallel fan powered terminal units to control the air flow in conditioned spaces. A laboratory verified model of single duct variable...
