Analysis on Suitability of Employing Aerogel Glazing System in Different Climate Zones

CHEN Youming, XIAO Yaling, ZHENG Siqian, LIU Yang

Abstract

The optical and dynamic heat-transfer models of aerogel glazing system were developed and validated by experiments. The models of other five common glazing systems (including double, triple and 3 kinds of Low-E double glazing systems) were also built based on the existing methods. The index of efficient solar energy was introduced to evaluate glazing's annual suitability, while the index of accumulative hourly heat gain was used to evaluate the glazing systems' suitability in the heating or the cooling season alone. The simulation results show that employing aerogel glazing system in severe cold region (Harbin), cold region (Beijing), hot-summer cold-winter region (Changsha) and temperate region (Kunming) can achieve energy efficiency. The differences of the efficient solar energy between aerogel and double glazing systems in these cities are 266.3, 158.6, 114.3 and 40.5 kWh/m2, respectively.
