Measured Baseline of a Double-Wide Manufactured Home Testbed: Hygrothermal and Energy Performance
A 1990 double-wide manufactured home (MH) dimensioned 26 ft × 40 ft with an area of 1,040 ft2 and total volume of 8,320 ft3 was installed and instrumented on Oak Ridge National Laboratory’s (ORNL) main campus in Oak Ridge, Tennessee to establish baseline (“as-is”) performance for envelope, airtightness, and space-conditioning energy use. The unoccupied test facility was in…

Thermal property characterization of phase change materials in building applications: A systematic review of fundamentals, recent progress, and future directions
Phase change materials (PCMs) can reduce building peak loads and enable demand-responsive thermal energy storage (TES), but their deployment depends on reliable measurement and interpretation of thermal properties across laboratory, intermediate, and application scales. This review systematically examines characterization methods, testing protocols, and recent advances for…

Thermoelectric heating and cooling–integrated dishwasher with thermal energy storage
Household dishwashers must address several performance goals: maximize washing and drying performance, while minimizing cycle duration, energy consumption, and water consumption. This study develops and examines a novel thermoelectric heating and cooling (TEHC) system with thermal energy storage applied to a household dishwasher (DW), aiming to improve the energy and dryin…

Multiscale characterization of phase change materials for building thermal energy storage applications
Phase change materials (PCMs) store and release large amounts of thermal energy because of their high latent energy storage capacity. However, long-term cyclic stability and subcooling issues are two of the major challenges for their use in building thermal energy storage (TES) applications. In this study, we conducted a comprehensive multiscale characterization of two com…

Novel PCM-based fin and tube heat exchanger system for building heating and cooling applications
In the United States, the building sector accounts for 40% of all energy use, and buildings are responsible for more than two-thirds of electricity consumption. Buildings remain the major driver of energy-related carbon emissions, and such emissions are projected to increase in the years ahead because of urbanization and population growth. To accomplish the low carbon ener…

Numerical Study of Liquid Piston Compression Using Large-Eddy Simulation and Volume-of-Fluid Approach
Efforts to increase the efficiency of residential and commercial air conditioners and heat pumps have demonstrated that the compressor accounts for most of the system’s electrical energy usage. Therefore, the efficiency of this component should be improved to reduce its energy usage. The US Department of Energy’s Oak Ridge National Laboratory developed a near-isothermal li…
