【摘要】：對相變材料在墻體中的封裝方式(直接混合、宏觀封裝、微觀封裝和定形相變材料封裝)、相變材料的種類和物性等方面的研究進行了歸納總結(jié).從實驗和模擬2個方面,對相變材料位于墻體表面和墻體內(nèi)部影響室內(nèi)環(huán)境和建筑能耗的研究進行了綜述和評價.分析表明,微觀封裝和定形相變材料的封裝效果較好;墻體用相變材料的相變溫度一般在20~30℃范圍內(nèi);相變材料層在墻體中的安裝位置可分為墻體表面和墻體內(nèi)部2種,但相變材料層在墻體內(nèi)的最優(yōu)位置并不固定,受相變材料物性、墻體材料以及室內(nèi)外環(huán)境工況的影響.通過相變材料與墻體合理高效的結(jié)合,可充分發(fā)揮相變材料的高蓄熱特性,提高墻體的熱性能,達到調(diào)節(jié)室內(nèi)環(huán)境溫度、降低建筑能耗的目的.
[Abstract]:In this paper, the encapsulation methods (direct mixing, macro encapsulation, microencapsulation and form-setting PCM encapsulation), the types and physical properties of PCMs in the wall are summarized and summarized. From the aspects of experiment and simulation, the research on the influence of phase change material on indoor environment and building energy consumption on the wall surface and the wall interior is summarized and evaluated. The results show that the encapsulation effect of microencapsulation and form-setting PCM is better, and the phase change temperature of PCM is generally in the range of 20 ~ 30 鈩，
