Abstract
The HVAC system accounts for 30 to 50 percent of a typical building's energy consumption; in hot & humid climates it is closer to the upper end of that range. Implementing effective energy saving measures for the building HVAC system can reduce the building energy consumption, reduce peak demand, and improve building comfort. The energy wheel is widely used in new system designs to recover/reject both sensible and latent heat energy from/to the exhaust airflow of air handling units. In this study, field measurements were conducted to evaluate the performance of one energy wheel installed in a SDVAV AHU serving an education building on a large university campus located in a hot and humid area. This paper also presents recommended optimization and performance improvement opportunities associated with this unit based on the performance evaluation.
