A new approach for dehumidifying air under refrigerator temperature situations: dehumidification with proton exchange membrane (PEM).
Number: pap. n. 1795
Author(s) : QI R., LI T., ZHANG L. Z.
Summary
A dehumidifier with Polymer electrolyte membrane (PEM), consisting of five layers of electrolyte, is suitable for the high-accuracy, limited-space humidity control for food storage, pharmaceutical and other chemical industries. It can be powered by low-voltage electric field (~3V), and has advantages such as ultra-compact (a few cm3), fast response, no drainage and no moving parts. In this study, the system performance of dehumidifying moist air below 0 °C with this innovation PEM is investigated experimentally, with our self-built test rig. At a sub-zero temperature of -5.5°C, the moisture removal rate increases almost proportionally with the increase in applied voltages at the range of 2~4V, which provides practical potentials for accurate controlling the novel dehumidifier by varying the voltages. When the voltage increases, the dehumidification efficiency also increased. Therefore, the new approach of dehumidifying moist air with PEM element can be a promising alternative for small-scale, high-requirement dehumidification under low temperature for refrigerators.
