摘要: 相变材料(Phase change materials, PCMs)在现代建筑材料中应用，具有稳定室内温度波动、提高热舒适性的巨大潜力；利用清洁能源太阳能，存储/释放热量，可降低建筑能耗，或达到削峰填谷的作用。本文重点讨论了不同气候条件下，PCMs对建筑室内温度和建筑能耗的影响；不同气候区域需选用不同相变温度的PCMs。PCMs适合应用在高海拔或早晚温差较大的地区，而不适宜应用在常年炎热或寒冷地带；四季气候分明的地区可采用两种相变温度的PCMs，而四季温和地区可采用相变温度为20℃~26℃的PCMs。
Abstract: Phase change materials (PCMs) have great potential to stabilize indoor temperature fluctuation and improve thermal comfort when be applied in modern building. This type of material can also increase the energy saving by absorbing clean solar energy to achieve peak clipping. The influence of PCMs on building indoor temperature and energy consumption at different climate conditions were discussed in this paper. In various climate conditions, different types of PCMs with distinct melting points should be selected. PCMs are suitable to be applicated in locations with high altitude or places with large temperature difference between daytime and night, but not applicable to constantly hot or cold zone. Two types of PCMs with different melting temperatures should be considered in the areas with distinct climate between seasons. In the case of constant climate, PCM with the melting temperature of 20˚C - 26˚C should be considered.
