建筑物在使用期间，需要不断消耗大量的能源，约占人类能源消耗的30%～40%，而其中绝大部分用于采暖和空调。而且，随着人口的增长，建筑高能耗也必成增长趋势，会给能源供应带来更大压力。建筑储能系统的发展成为解决问题的方案之一。

    During the period of use, buildings need to continuously consume a large amount of energy, which accounts for about 30% to 40% of human energy consumption, and most of them are used for heating and air conditioning. Moreover, as the population grows, the high energy consumption of buildings is bound to increase, which will put more pressure on energy supply. The development of building energy storage systems has become one of the solutions to the problem.

    相变材料（PCM）是一种利用相变潜热吸收、储存和释放热能的材料。采用微胶囊技术对相变材料进行封装，制成稳定的微胶囊相变材料（MCPCM）固体微粒，这种微粒可以在很窄的温度范围内吸收/释放相变潜热，具有较为显著的储热调温功能。将微胶囊相变材料应用于建筑内墙涂料，可降低室内空气温度波动的频率，保持温度在一个较长的时期内与所需的温度接近，增加人体舒适度，同时达到节能目的。

    Phase change material (PCM) is a material that uses the latent heat of phase change to absorb, store and release thermal energy. Microcapsule technology is used to encapsulate the phase change material to make stable microcapsule phase change material (MCPCM) solid particles, which can absorb/release the latent heat of phase change in a narrow temperature range and have significant heat storage Temperature adjustment function. The use of microcapsule phase change materials in building interior wall coatings can reduce the frequency of indoor air temperature fluctuations, keep the temperature close to the required temperature for a long period of time, increase human comfort, and achieve the purpose of energy saving.
