Design and Application Research of Shape-Stabilized Phase Change Materials for Building Energy Conservation
摘要
Abstract
Phase change energy storage materials have advantages such as high energy storage density,stable performance,recyclability and environmental friendliness,making them promising for wide applications in the field of construction. This paper focuses on the research of palm oil methyl ester-lauric acid eutectic phase change materials with white carbon black and dodecanol as stabilizers and SEBS as supporting materials. It investigates the influence of different material ratios on the phase transition temperature and latent heat of the phase change materials. Additionally,microencapsulation technology is employed to combine the palm oil methyl ester-lauric acid eutectic phase change materials with gypsum building materials,creating a phase change simulation room to explore its feasibility in the construction field. The research results show that when m (methyl palmitate):m(lauric acid)=6∶4,the phase transition temperature is 24.5～28.5 ℃ and the latent heat of phase transition is 172.0 kJ/kg,both of which are suitable for the construction field;The original enthalpy of phase change during the melting process of phase change materials is 172.0 kJ/kg,which changes to 167.3 kJ/kg after 200 cycles,and the thermal conductivity is 0.256 W/(m·K);The simulated room without adding phase change materials heats up and cools down faster under simulated sunlight from infrared lamps than the simulated room with organic eutectic phase change materials. The addition of phase change energy storage materials has a significant regulating effect on indoor temperature in buildings.关键词
