Performance of heat exchangers greatly suffers due to maldistribution of fluid, which also impacts the performance of the entire HVAC system. One method to reduce fluid maldistribution is to improve the design of the manifold to make the flow evenly distributed.
Commercial closed-cell insulation foam boards reduce their thermal resistivity by up to 30% due to gas diffusion in and out of foam cells.
Moisture management accounts for over 40% of the energy used by buildings. As such development of energy efficient and resilient dehumidification technologies are critical to decarbonize the building energy sector.
ORNL has developed a new thermal energy storage design utilizing low conductivity organic phase change materials.
The invention addresses the long-standing challenge of inorganic phase change materials use in buildings envelope and other applications by encapsulating them in a secondary sheath.
Buildings are energy intensive and contribute to carbon dioxide emissions while accounting for one-third of energy consumption worldwide. Heat pump technology can assist in electrification and decarbonization efforts.
The technologies described herein provides for the High Temperature Carbonization (HTC) in the manufacturing of carbon fibers (CF). The conventional method for HTC is based in thermal radiation and this technology uses in a liquid medium.
Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
