建筑物在使用期間，需要不斷消耗大量的能源，約占人類能源消耗的30%～40%，而其中絕大部分用于采暖和空調(diào)。而且，隨著人口的增長，建筑高能耗也必成增長趨勢(shì)，會(huì)給能源供應(yīng)帶來更大壓力。建筑儲(chǔ)能系統(tǒng)的發(fā)展成為解決問題的方案之一。

    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.

    相變材料（PCM）是一種利用相變潛熱吸收、儲(chǔ)存和釋放熱能的材料。采用微膠囊技術(shù)對(duì)相變材料進(jìn)行封裝，制成穩(wěn)定的微膠囊相變材料（MCPCM）固體微粒，這種微粒可以在很窄的溫度范圍內(nèi)吸收/釋放相變潛熱，具有較為顯著的儲(chǔ)熱調(diào)溫功能。將微膠囊相變材料應(yīng)用于建筑內(nèi)墻涂料，可降低室內(nèi)空氣溫度波動(dòng)的頻率，保持溫度在一個(gè)較長的時(shí)期內(nèi)與所需的溫度接近，增加人體舒適度，同時(shí)達(dá)到節(jié)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.
