Authors Subhrajit Chakraborty, David Vernon, Apoorva Jha and Vinod Narayanan analyze the potential of utilizing a novel indirect evaporative cooler (IEC) that can efficiently cool building ventilation air in the hot summer months, and be used as a heat recovery ventilator in winter months. Their laboratory testing of this equipment showed significant energy savings potential, and validated their IEC physics-based model. Ultimately, this will lead to accurate modeling of this energy saving technology over a variety of buildings and climates.
