摘　　要：本文以一制药厂低湿工艺空调系统的改造为例,对冷冻除湿系统、液体除湿系统及其低品位余热利用方案进行了能量和分析,提出了利用低品位余热作为液体除湿系统再生热的冷凝热回收热泵复合系统,系统全年再生热节能率可达45.1%。本文结论可为工业低湿厂房液体除湿系统的低品位余热利用提供指导。In this paper,taking the retrofit project of an industrial low humidity air-conditioning system in pharmaceutical factory as an example,the energy and exergy analysis was carried out for the refrigeration dehumidification system,liquid desiccant system and its low-grade waste heat utilization scheme.And then,condensation heat recovery and heat pump combined system was presented,in which the low-grade waste heat was used as solution regenerated heat for the liquid desiccant system.The energy-saving rate of regenerated heat during the whole year was up to 45.1%.The conclusions in this paper could provide references for the application of liquid desiccant system with low-grade waste heat in industrial low humidity workshop.
