Wide-distribution cold air storage frozen soil roadbed and refrigeration method
The invention relates to the technical field of frozen soil engineering, in particular to a widely-distributed cold air storage frozen soil roadbed and a refrigeration method. The widely-distributed cold air storage frozen soil roadbed comprises an air cooling regulation and control unit, an air power unit, a refrigeration unit, a temperature sensing unit and a control unit; the air cooling regulation and control unit comprises phase-change heat-exchange cold storage bodies, an air cooling box body, an air exhaust channel and air circulation channels, the multiple phase-change heat-exchange cold storage bodies are evenly distributed in the air cooling box body at intervals, and the multiple air circulation channels which are arranged in parallel at intervals and extend to the outer side of the air cooling box body are arranged among the multiple phase-change heat-exchange cold storage bodies; every two adjacent air circulation channels on the inner side of the air cooling box body are distributed in a staggered mode. By judging the temperature in the air cooling box body and the temperature of the external environment, an external circulation refrigeration mode and an internal circulation refrigeration mode are arranged to complement each other, and the effect of efficiently cooling the frozen soil roadbed is achieved through comprehensive utilization of modes such as forced convection and slow-release heat absorption of the phase-change heat exchange cold storage body.
本发明涉及冻土工程技术领域，是一种广布式蓄冷气冷冻土路基及制冷方法，其前者包括气冷调控单元、空气动力单元、制冷单元、温度感应单元和控制单元；气冷调控单元包括相变换热蓄冷体、气冷箱体、空气排出通道和空气循环通道，气冷箱体内间隔均布有多个相变换热蓄冷体，多个相变换热蓄冷体之间设有多个平行且间隔设置并延伸至气冷箱体外侧的空气循环通道，且气冷箱体内侧相邻的两个空气循环通道交错分布；本发明通过对气冷箱体内的温度和外部环境温度的判断，设置外循环制冷和内循环制冷模式相互补充，通过强迫对流、相变换热蓄冷体进行缓释吸热等模式的综合利用，达到冻土路基高效降温的效果。
