液体除湿与排风热回收相结合的新风处理系统

摘要

The system employs the technique of temperature & humidity independent processing, improving the chilled water temperature for air conditioning. Presents respectively the psychrometric chart and system flow chart of the outdoor air handling system by single liquid desiccant system and liquid desiccant combined with enthalpy exchanger. With an actual energy efficient retrofit example, analyses the energy conservation effect and emission reduction. The result shows a favorable effect of 1.36 GJ/h energy conservation and 132.5 kg/h emission reduction in the design condition.%该系统能实现温度湿度独立控制,提高空调冷水温度.介绍了液体除湿独立处理新风和液体除湿与全热换热器共同处理新风的焓湿图和系统流程图.结合对某工程的节能改造,分析了节能效益及减排量.结果表明,应用该系统在设计工况下可获得冷量1.36 GJ/h,CO2减排量132.5 kg/h,节能减排效果显著.
