Abstract：
Tests and analyses the moisture absorption and desorption properties of the applicable desiccant for enthalpy wheel heat exchanger such as silica gel, molecular sieve and absorbent polymer. Makes a silica gel enthalpy wheel heat exchanger by adopting optimized desiccant coating processes and tests its properties, and the results show that its total heat recovery efficiency is 15% higher than that of 3A molecular sieve wheel heat exchanger.
Keywords:desiccant, moisture absorption and desorption rate, wheel, total heat recovery efficiency
