High heat source temperature is the main factor that limits the adoption of low-temperature and high efficient heat sources. The adiabatic and inner cooling desiccant dehumidification devices and air handling processes are researched in this project. Based on temperature and humidity ratio fields of heat and mass transfer devices, through performance tests, fields distribution simulation and exergy destruction analysis, the influencing principles of temperature and humidity ratio fields on the driving temperature are revealed and guidelines for the design of low-temperature driven high efficient adsorption dehumidification units and air handling processes are proposed. The following are mainly researched: improved models and experiment validation of desiccant wheels and inner cooling desiccant beds; simulation analysis of the effects of each parameter on the driving temperature and temperature and humidity ratio fields; proposing indexes that can describe the field distribution features of desiccant material, air and cold/hot fluids of inner cooling desiccant bed, and analyzing the influencing principles of field distribution on the driving temperature; proposing low temperature driven high efficient innovative systems and air handling processes based on fields optimization. This project aims to elaborate the characteristics of temperature and humidity ratio fields, to reveal the influencing principles of field distributions on the driving temperature, and to realize low temperature driven high efficient solid dehumidification systems based on field optimization.
