Abstract

Abstract:

CA-MA/EP-shaped phase-change material (PCM) was prepared by melt adsorption with expanded perlite (EP) as the carrier and CA-MA binary fatty acid as the phase-change core material. CA-MA/EP (mass ratio = 1∶1) coated with white latex was mixed into the gypsum matrix to prepare the phase-change energy storage board to alleviate the leakage of fatty acid during the solid-liquid phase-change process. The thermal conductivity, thermal physical properties, and specific heat capacity were tested. The exudation stability evaluation's finding supported the white latex coating's capacity to successfully reduce fatty acid exudation from EP, and the mass loss rate of the CA-MA/EP-shaped PCM was reduced from 8% to 4%, further strengthening EP's ability to shape fatty acid. In the meanwhile, the long-term energy storage stability and aesthetics of the phase-change energy storage board were improved. The phase-change temperature and latent heat of CA-MA/EP and phase-change energy storage board were 24.64 ℃ and 58.07 J/g, and 24.62 ℃ and 29.10 J/g, respectively. As the content of shaped PCM rose, the thermal conductivity steadily decreased. The energy plus software was used to simulate the indoor temperature fluctuation of the building based on the phase-change building envelope under the summer climate conditions of Xuzhou. It was confirmed that the phase-change energy storage board has the effect of heat insulation and temperature control.

Key words: fatty acid, phase change energy storage board, temperature control effect, simulation
