Design and Development of Vortex Tube Ice-making and Cold-storage Device for Refuge Chamber
LIU Pengcheng
Abstract：In this paper,analysis and comparison were made on the the advantages and disadvantages of the commonly-used refrigeration modes in the refuge chamber. By orthogonal experiment,it came to the conclusions that the main factors affecting the vortex tube refrigeration power were the air supply temperature and pressure and the secondary factor was the cold flow rate;the evaporator adopted the secondary circulation spiral red copper tube structure and its heat-transfer power was 156. 5 W. The ice-making test results showed that under the conditions of the air supply flow rate of 10. 8 L/s,the pressure of 0. 6 MPa and the cold flow rate of 0. 6,it can make a certain amount of water condense into ice within 30 h,this conclusion provided a new solution and ideal for the refrigeration in refuge chamber.
