System and Performance of Liquid Desiccant Air Conditioner

摘要

Liquid desiccant air conditioning system presented in this paper realizes independent humidity control, avoids energy loss in the freezing dehumidification process and has a higher efficiency than any other desiccant cooling systems. It can be driven by low-grade heat source (90°C ～ 60°C) with high energy efficiency, and it seems to be no satisfied methods for other existing technologies to use such low temperature heat source. The equipment can realize optimized heat and mass transfer process. Simulation results show that this system has good performance. This new system can be applied in CHP systems, and it's an effective mode to optimize urban energy supply system.
