← ScienceWhich effect on an industrial dehumidifier utilizing a desiccant wheel running with increased angular velocity and insufficient airflow results when saturated?
A)Sublimation heat reduces capacity rapidly
B)Adsorption declines sharply from saturation✓
C)Evaporation rate balances quicker overall
D)Condensation reverses in high humidity
💡 Explanation
Adsorption declines from bed saturation because reduced airflow impairs the process and heat transfer becomes rate-limiting. It is the **adsorption isotherm** that becomes less steep at saturation, therefore further adsorption decreases disproportionately, rather than enabling rates changing in other ways.
