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.

可逆气流穿过吸收蓄热填料固定层的非稳态传热传质实验研究

摘要

本文介绍了气流通过吸附剂和蓄热填料固定层的可逆模式下的非稳态传热传质实验研究的结果。蓄热填料采用多分散成分、平均粒径12.6mm的砾石筛分，采用直径2.8mm、长度5mm～7mm的圆柱形复合吸附剂IK-011-1颗粒作为蓄热填料。吸附剂。供给空气的流量为253m ³ /h。研究表明，热回收率的变化范围为0.80至0.91，水分回收率的变化范围为0.60至0.84。有了这样的速率，再生式热质传递装置就成为在通风系统中利用热量和湿气的有前途的设备。
