摘要(Abstract):
提出了一种基于间接蒸发冷却内冷式液体除湿器(IPHE),并与绝热除湿器(APHE)的性能进行了比较。为了提高除湿性能,采用纳米二氧化钛改变内冷除湿器(WPHE)的润湿面积,之后比较分析了3种除湿方式中一次空气含湿量、流量和温度对除湿性能的影响。结果表明,与间接蒸发冷却内冷式液体除湿器(IPHE)相比,当分别改变一次空气含湿量、流量和温度时,绝热除湿器(APHE)的除湿量?M、板换效率e和传质系数h_p较早达到除湿极限。此外,与间接蒸发冷却内冷式液体除湿器(IPHE)相比,改变润湿面积后的内冷除湿器(WPHE)的除湿量?M、板换效率e和传质系数h_p分别提高了7%~20%,80%~120%和25%~52%。
An internally cooled liquid dehumidifier(IPHE) based on indirect evaporative cooling was proposed and was compared with the adiabatic dehumidifier(APHE).In order to improve the dehumidification performance,nano-titanium dioxide was used to change the wetting area of the dehumidifier(WPHE).Then the effects of primary air moisture content,flow rate and temperature on dehumidification performance were analyzed and compared among the three types of dehumidification.The results show that compared with IPHE,when the primary air moisture content,flow rate and temperature were changed respectively,the dehumidification capacity ?M,plate exchange efficiency e and mass transfer coefficient h_p of APHE reached the dehumidification limit earlier than those of IPHE.In addition,compared with IPHE,the dehumidification amount ?M,plate exchange efficiency e and mass transfer coefficient of WPHE after changing the wetting area were increased by 7%~20%,80%~120% and 25%~52%,respectively.
