Basic experimental study on application of phase change energy storage wall to refuge chamber

摘要

摘要: 提出了一种避难硐室相变储能墙体蓄热控温的方法，即常规状态下矿井压风、储能墙体相变蓄冷，发生矿难时墙体相变吸热的耦合控温方法；将硅藻土基相变材料作为储能骨料添加物制备复合水泥砂浆后敷设到避难硐室墙体，达到控温效果。试验结果显示：当储能骨料掺入量为15%，活性炭的掺入量为6%，制备的复合水泥砂浆可适应用到避难硐室的储能墙体结构中，改善避难硐室内热环境。

Abstract: A method of heat storage and temperature control for refuge chamber with phase change energy storage wall is put forward, that is, coupled temperature control method of mine air pressure, phase change cold storage for energy storage wall under conventional condition, and wall phase change heat absorption when mine accident occurs, the diatomaceous earth-based phase change material was used as the energy storage aggregate additive to prepare composite cement mortar, which was then laid on the wall of the refuge chamber to achieve temperature control effect. The test results show that when the amount of energy storage aggregate is 15% and the amount of activated carbon is 6%, the prepared composite cement mortar can be adapted to the energy storage wall structure of the refuge chamber and improve the indoor thermal environment of the refuge chamber.
