jismart2023017: Experimental Study of Modified Trombe Wall Oriented to Heat and Humidity Performance

Abstract

The indoor humidity environment is critical for indoor air quality, energy consumption of air-conditioning systems, and durability of the envelope. Commonly used methods of indoor humidity regulation, such as the use of air conditioning devices, are not conducive to sustainability. Cellulose fibre insulation, as an insulating material, not only has good insulating properties but also has good humidity regulation capabilities, which can passively regulate indoor humidity fluctuations and thus reduce building energy consumption. In this study, paper cellulose insulating material is combined with Trombe Wall to regulate the indoor temperature using passive solar technology while regulating the indoor humidity using the characteristics of paper fibers to achieve the function of separating latent heat and sensible heat, and to achieve the effect of dehumidification and cooling in summer and heat collection in winter. In this paper, an experimental room was constructed, and its thermal and humidity performance was studied, and the experimental results proved that this modified Trombe Wall has a positive effect on the regulation of indoor humidity. This study is of great significance in solving the energy loss caused by the unified treatment of heat and humidity.
