Modeling And Optimization Of Desiccant Cooling System

In this paper,the thermodynamic analysis of liquid desiccant cooling systemhave been carried out, on this basis established the heat and mass transfer modelof main component. Inner cooling cross-flow plate dehumidifier, adiabaticregenerator and indirect plate type evaporator were adopted in the system. On thebasis of mathematical model, computational programs have been compiled tosimulate air handling process, predict the system performance and analyze theinfluence factor on system performance. The result shows that the coefficient ofperformance is low in general. And the system has advantages hot and humid area.To resolve low system performance coefficient, step-desiccant technique wasintroduced in system design. Use the analytical hierarchy process to optimizedesign. The optimizing result shows that the effect of multi-step liquid desiccantcooling system is better than single step system.
