Review on photo-thermal performances of phase change materials smart windows
Phase Change Materials(PCM)were utilized to enhance the thermal storage performance of windows,thereby re-ducing building energy consumption and shifting peak indoor temperatures.The selection and application of PCM,their arrange-ment,and encapsulation methods were involved in this process.Simulations and experimental research on the photo-thermal performance of PCM windows were analyzed in the study.The key strategies for performance enhancement were identified:win-dow structure optimization(from double to triple glazing),improvement of the thermal properties of existing PCMs(addition of nanofluids for enhanced thermal conductivity)and integration with other glass technologies(thermochromic glass,Low-e glass,aerogel).Micro-Electro-Mechanical System(MEMS)was coupled with PCM in high-performance windows which could ad-just light incident angle intelligently to improve indoor light and thermal environment while reducing building energy consumption.Finally,current issues and future development directions for PCM windows were addressed in terms of material modification,photo-thermal synergy and technological integration.
