Benchmarking Thermal Comfort Performance of Two Residential Air Distribution Systems in a Low- Load Home



Hyojin Kim, Khiem Nguyen, Lisa C. Ng, Brian P. Dougherty, William V. Payne


Despite broad recognition that air distribution plays an important role in comfort for residential buildings, few studies have addressed the fundamental ability of residential air distribution systems to produce and deliver the selected setpoint temperature throughout a house over time. To address this deficiency, this paper compares the long-term thermal comfort performance of two different air distribution systems by using multiple benchmarks. The two systems, a Conventionally-Ducted Heat Pump (CDHP) and a Small Duct High Velocity (SDHV) heat pump, were used to condition the same test house, the Net-Zero Energy Residential Test Facility (NZERTF) that is located on the campus of the National Institute of Standards and Technology (NIST) in Gaithersburg, MD, USA
