Abstract
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.
