Independent humidity control air-conditioning system using liquid desiccant

A new kind of air-conditioning system, the humidity independent control system based on the liquid desiccant air processor has presented in the present study, through the problems analysis on current air-conditioning systems. The operating principle of the liquid desiccant air processor and the configuration of the new system have been described in detail. The advantages and special features have been discussed such as the improvement on IAQ, as well as the benefit on energy saving. It is concluded that the liquid desiccant system can reduce the mold and dust from the air effectively. Humidity and temperature can be controlled individually through different terminals by different means, which will greatly improve IAQ and thermal comfort. Due to the dehumidification has done by the desiccant, chilled water is not necessary for drying the air, only 15 similar to 18 degrees C water is needed to absorb heat during the dehumidification process and the sensible heat.
