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.
High and ultra-high vacuum applications require seals that do not allow leaks. O-rings can break down over time, due to aging and exposure to radiation. Metallic seals can damage sealing surfaces, making replacement of the original seal very difficult.
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.
