The experiments show that the designed TES unit can store maximally thermal energy for near 4510 kJ within 250 min, while the latent heat occupies 15 % at fan speed 25 RPM and the heater power with 2 ...

Tremendous low-grade heat is stored in industrial processes and the environment. Efficient and low-cost utilization of the low-grade heat is critical to imminent energy and environmental challenges.

Low-grade heat from sources below 100 ∘C offers a vast quantity of energy. The ability to extract this energy, however, is limited with existing technologies as they are not well-suited to ...
