Abstract

Liquid desiccant air conditioning system with condensing heat regeneration was presented in this paper, which integrated vapour compression refrigeration system and liquid desiccant system. The heat rejected from the condenser was used to regenerate the liquid desiccant to improve the performance of system and conserve energy. The influences of inlet parameters such as air, solution on the performance of liquid desiccant air conditioning system with condensing heat regeneration were discussed. Research results demonstrated that liquid desiccant air conditioning system with condensing heat regeneration had remarkable energy saving effect when it was used to reduce the moisture content of fresh air in summer, and characteristics of evaporative condensing regenerator played an important role in performance of system. The COP of liquid desiccant system is 1.18 higher than vapour compression refrigeration system.
