Full Description

The performance of portable disk humidifiers relies on water vaporized into dry air. Among various kinds of humidifiers, a disk humidifier comprises of disks as a water vaporizing means. An experimental study was conducted to improve humidifier performance using three kinds of polymer disks: polypropylene (PP), acrylonitrile butadiene styrene (ABS), and compounded PP. The hydrophilicities of PP, ABS, and compoundedPPwere 86, 90, and 55, respectively.We tested the humidification rates of humidifiers with disks roughened by 24, 30, and 40 m (9.45 10-4, 1.18 10-3, and 1.57 10-3 in.) of fine sand using a sandblasting process for three kinds of disks. The compounded PP humidifier vaporized about 1.3-1.4 times more moisture than the other types. The 24 m (9.45 10-4 in.) sand treated disk humidifier showed the best results, humidifying 1.57-1.7 times more than the original disk humidifier. These results suggest that humidifier performance could be enhanced with the use of hydrophilicrough disks without requiring any additional electrical energy.
