Design and Research of Vortex-Tube-Ice-Storage System Used in Refuge Chamber

When disasters occur under coal mines, the electric power system and compressed air system would be highly vulnerable to damage, while heat load will be produced in the chamber because of victims’ metabolism and equipments’ operation, so it is crucial to control temperature in the chamber effectively. This paper presents a new type of vortex tube ice storage refrigeration technology, and the property of a vortex tube is tested and theory of the ice storage system is studied, then the ice making time and the best working state are obtained. It provides theoretical basis for ice storage refrigeration of mine rescue, and it is of important reference value for engineering design.
