Summary

TriCoilTM is a novel three-fluid fin and tube heat exchanger that enables integration of thermal energy storage (TES) with residential heating, ventilation, and air conditioning (HVAC) systems. A unique feature of TriCoilTM is that it allows direct refrigerant-to-air cooling and heating operation. This study compares the performance of three new circuit arrangements with the first-generation design. We used a validated model of TriCoilTM, based on OSU CIBS’s discretized xFin model, to explore circuit arrangements of the coil for cooling applications. Coil capacity and thermohydraulic effectiveness on the water side are considered as the primary performance parameters. Initial findings suggest that a specific circuit arrangement can reduce water-side pump power consumption by 37% while enhancing coil hydronic operation capacity by 13% compared to previous design. We assess system-level application through parametric study of latent capacity in continuous discharge operation. Here, we also present the differences in heat exchanger performance for direct (refrigerant-to-air) cooling operation.
