- Abstract:
- Mass transfer passage was used inside the packed bed of enchance steam generation efficiency in a novel adsorption heat pump by utilizing a direct-contact heat exchange method. Ratios of the passage to inner diameter of the packed bed were 10% and 20%. Experimental results from 10% passage showed that the maximum generated steam temperature reached 236℃, which increased by 23ºc compared to that without passage. Meanwhile the mass of steam mass increased by 26%, mass ratio of steam to dry zeolite(ms,out/mz) increased by 14%, and steam generation time increased by 1.8%. Experimental results from 20% passage showed that the maximum steam temperature only increased by 11ºc; steam mass increased by 5.6%, ms,out/mzn was almost unchanged; steam generation time increased by 25.3%. Superheated steam generation rate was faster for large passage, while the maximum temperature and mass of generated steam were higher for small passage.
