Abstract
Indoor air humidity (IAH) is one of the most important factors in the determination of in-door environmental conditions and thermal comfort. However, during the heating period in cold climates it has been reported that indoor relative humidity is often lower than 30%. This paper focused on indoor low air humidity and explored the solution to solve the issue based on a simple experiment. It was found that natural evaporation of water from the vertically wetted fiber fabric could effectively improve IAH. Both evaporation rate and evaporation quantity of water from wetted porous fiber fabric had significant influences on attainable maximum value of IAH. In addition, it was worth noting that the entire regulating process did not need to consume energy.
