Energy aspects of HVAC system configurations — problem definition and test cases
journal contribution
posted on 2008-10-09, 10:40 authored by Yi Zhang, Jonathan WrightJonathan Wright, Victor I. HanbyThis paper reports on the energy implications of HVAC system configuration by analyzing the
energy balance and psychrometrics of typical and innovative systems. Three criteria were
shown to be significant: (1) the ability to minimize outside air load, (2) the ability to eliminate
simultaneous cooling and heating and use mixing effectively, and (3) the availability of interzonal
airflow. Configurations that meet these criteria would be able to deliver the desired
indoor air quality with reduced energy consumption. The performance of ten two-zone system
configurations, including single-duct, dual-duct, fan-coil-based variations, and other specialized
systems in the literature, were analyzed for a number of operational conditions. The results
confirmed that fan-coil-based configurations with interzonal airflow paths perform better than
other configurations. The conclusion of this study may be used as a guideline for multi-zone system
designs.
