文摘

Owing to its light weight, good seismic performance and high degree of industrialization, lightweight building is used widely. However, due to the low thermal inertia of lightweight building envelop, its indoor temperature is highly affected by outdoor ambient. So the application of lightweight building is restricted because of its poor indoor thermal environment. In order to improve the thermal performance, this paper researches lightweight building integrated with phase change material (PCM). EnergyPlus software with building model validated by experiment data is used to research the indoor thermal environment improvement with PCM under typical weather conditions of five climate zones in China. Results show that PCM can effectively control the indoor temperature rises and temperature fluctuations. And in temperate region, the PCM can improve indoor thermal environment of lightweight building in most of the time throughout the year.
