Application of ice-storage air-condition in rescue capsulefor coal mine

Rescue capsule is of great significance in ensuring the safety of the miners in mine disasters.The application of air-condition refrigeration technique is also very important in the avoidance of high temperature and heat,which is advantageous for the miners' health and safety.In this paper,based on the analysis of air-condition systems for coal mine,the principle of ice-storage air-condition system is mainly described.The comparison between the single-circle and double-circle ice-storage air-condition systems suggests that single-circle system is superior in some extent.Based on the experimental data,the validity of single-circle system is demonstrated.
