Abstract:
Adsorption heat pumping is eco-friendly application that enables energy saving. Process efficiency can be increased by heat transfer enhancement with adsorber-heat-exchanger optimization. Two different methods for measuring metal-sorbent heat transfer coefficients α are discussed: Large Temperature/Pressure Jump. Novel composite LiCl/highly-porous silica was used as sorbent. These methods simulate adsorption heat storage cycle and give possibility to measure α for grains with size D = 0.8–0.9, 0.4–0.5 and 0.2–0.25 mm. The coefficients measured by different methods are close: 160–170 W/m2K for the largest, 250–270 W/m2K for intermediate and 420–460 W/m2K for the smallest grains. The linear function connecting α and 1/D was found.
