In manufacturing parts for industry using traditional molds and dies, about 70 percent to 80 percent of the time it takes to create a part is a result of a relatively slow cooling process.
The technologies described provides methods for enhancing thermal efficiency of phase change materials.
To promote all electrification and maximize use of renewable energy, electric driven heat pumps need to incorporate energy storage functions.
A novel high flux direct air capture (HiDAC) contactor is developed by using materials to increase the effective surface area for CO2-solvent contact.
A low-cost heat exchanger design was developed to increase the charge and discharge time of high-energy density phase change materials. This heat exchanger utilizes less than 10% of the storage volume and ensures 90% discharge in 4 hours - the typical length of a shed event.
High energy density silicon electrodes suffer from (1) low porosity and (2) high tortuosity which limits electrode performance and silicon utilization.
Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.
Heat pumps and refrigeration equipment undergo intermittent defrosting/deicing cycles to remove undesired ice and frost layer from the evaporator surfaces. This process consumes significant amount of energy.
We developed an innovative fabrication process to cost effectively produce complex geometric radiation shields. Radiation shields often utilize materials that are difficult to manufacture and require significant labor costs.
