摘要
含冰粒的载/蓄冷充填降温是解决深井热害问题的有效方式,但其制冰能耗大、系统运行费用较高。为此,研发了基于太阳能吸附制冷的矿井载/蓄冷充填降温系统(Mine Cold Load/Storage Backfill Cooling System Based on Solar Adsorption Refrigeration),该系统由地面太阳能集热子系统、吸附制冷子系统和地下输冰子系统组成。通过建立子系统的数学模型和地面系统的TRNSYS模型,分别分析甲醇解吸量、吸附制冷量和吸附制冰量在不同太阳能辐射强度、不同季节和不同地区影响下的变化规律,进而得出太阳辐射强度和太阳辐射连续性是造成制冰量差异的主要原因。选取太阳辐射强度和太阳连续性较优的淮南、南宁两区域进行系统制冰能效分析,与传统蒸汽压缩式制冷系统相比,该系统的吸附制冷子系统平均节能效率达到64.71%。研究结果反映出,太阳能吸附制冷与载/蓄冷充填降温相结合的新型矿井降温系统的研发,对于高效解决矿井热害问题有所裨益。
The load/storage filling cooling with ice particles is an effective way to solve the problem of thermal damage in deep Wells,but its ice production energy consumption is large and the system operation cost is high.For this reason,Mine Cold Load/Storage Backfill Cooling System Based on Solar Adsorption Refrigeration was developed.The system consists of surface solar heat collection subsystem,adsorption refrigeration subsystem and underground ice delivery subsystem.Through the establishment of the mathematical model of the subsystem and the TRNSYS model of the ground system,the variation rules of the methanol resolution capacity,adsorption refrigeration capacity and adsorption ice production capacity under the influence of different solar radiation intensity,different seasons and different regions were analyzed respectively,and it was concluded that the solar radiation intensity and solar continuity were the main reasons for the difference of the ice production capacity.Huainan and Nanning regions with superior solar radiation intensity and solar continuity were selected to analyze the ice making energy efficiency of the developed system.The results show that compared with the traditional steam compression refrigeration system,the average energy saving efficiency of the adsorption refrigeration subsystem of the system reaches 64.71%.The research results show that the research and development of a new mine cooling system combining solar adsorption refrigeration with load/storage filling cooling is beneficial to efficiently solve the problem of mine thermal damage.
