Experimental Investigations of Non-Stationary Heat and Mass Transfer with Reversible Air Flow through Fixed Layers of Absorbent and Heat-Accumulating Packing
The paper presents the results of an experimental study of non-stationary heat and mass transfer in reversible modes of air flow through fixed layers of an adsorbent and a heat-accumulating packing. Gravel screening with polydisperse composition and average particle size of 12.6 mm was used as a heat-accumulating packing, and composite adsorbent IK-011-1 granules of cylindrical shape with diameter of 2.8 mm and length of 5 mm to 7 mm were used as a sorbent. The flow rate of the supplied air was 253 m3/h. The studies showed that the heat recovery rate varied in the range from 0.80 to 0.91, and the moisture recovery rate ranged from 0.60 to 0.84. With such rates, a regenerative heat-and-mass transfer setup becomes a promising device for utilizing heat and moisture in a ventilation system.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
