吸收式制冷在深部矿井高温热害处理中的应用与FLUENT模拟计算

摘要

For mine deep heat damage problem, effective use of low-grade waste heat of the Swallet, as the driving heat absorption refrigeration constructed absorption refrigeration, resolve deep coal thermal damage circulatory system through the use of deep water source heat pump heated gushing, so lithium bromide absorption chiller cooling at the same time on the working surface, as the heat absorption refrigeration cycle using design using auxiliary heating source heat pump to drive the refrigeration unit Swallet system. Fluent use of numerical simulation of the text, comparative analysis of the effect of coal mine deep under the best air cooling conditions, to provide a theoretical basis for the absorption refrigeration technology in actual use in deep.%针对煤矿深部热害问题，提出了利用矿井涌水中的低品位废热，作为吸收式制冷的驱动热源，构建了吸收式制冷循环系统解决煤矿深部开采工作面热害问题。依据煤矿深井开采工作面热舒适度要求，对制冷降温系统热参数进行估算；运用Fluent数值模拟，对比分析出最佳送风条件下的煤矿深井制冷效果。理论分析与数值模拟结果表明了采用吸收式制冷循环解决煤矿深井开采工作面热害问题可行性。
