Abstract
In this study, new materials and shapes for a residential humidifying element were investigated. These elements could replace the current Japanese folded-type rayon/PE elements. Samples were taken from three different materials - rayon/PET (50:50), kraft/PET (40:60), kraft/PET/carbon. Results showed that the humidification efficiencies of the new samples were lower than those of the Japanese product. The efficiencies were 59% for the Japanese product (rayon/PET), 62% for kraft/PET and 84% for kraft/PET/carbon. This could be due to lower rayon or kraft content in the present samples than that in the Japanese product. However, pressure drops in the present samples were significantly lower than that in the Japanese product, due to improved channel configuration. The humidification capacity at the same pumping power ($j_m/f^{1/3}$) was 60% to 82% higher for the kraft/PET/carbon sample compared with the Japanese product. Furthermore, the results are compared with theoretical predictions.
