溶液除湿方式对室内空气品质影响的初步研究【英文篇名】 Pilot study of the impact of liquid desiccant dehumidification on IAQ 【作者中文名】 张伟荣; 曲凯阳; 刘晓华; 常晓敏; 【作者英文名】 By Zhang Weirong ★; Qu Kaiyang; Liu Xiaohua and Chang Xiaomin★Tsinghua University; Beijing; China; 【作者单位】 清华大学; 【文献出处】 暖通空调, Hv 室内空气品质; 空气污染物; 细菌灭活; 除尘; 【英文关键词】 liquid desiccant; IAQ; aerial pollutant; sterilization; dust catching; 【摘要】 在溶液除湿空调空气处理过程中 ,因溶液与空气直接接触 ,可能对室内空气品质产生负面影响 ,但同时也可以去除空气中的有害物质。以溴化锂溶液为例 ,进行了室内空气溴、锂离子的测定 ,溴化锂溶液对甲醛的吸收实验 ,除湿溶液对细菌和病毒生长的影响实验 ,并初步探讨了气液交换模块的除尘作用 【英文摘要】 The direct contact of liquid desiccant with air in liquid desiccant air conditioning systems will result in both adverse and favourable impacts on indoor air quality. Ions of bromine and lithium may be brought into the occupied space by the processed air but the aqueous solution used in the system can remove some aerial pollutants and sterilize the bacteria and virus. Discusses the impact of liquid desiccant dehumidification using lithium bromide solution on IAQ. Tests the quantity of Li + and Br - in air...
