Experiment and analysis of desiccant coating processes for enthalpy wheel heat exchangers

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.
