Abstract:

Due to the fact that the conventional ice slurry production system using supercooled water suffers from ice block and depends heavily on electric power, a novel ice slurry production system is proposed. The new system consists of two major parts: the evaporative supercooling process and the liquid dehumidification process.The classical diffusion-control equation is improved by introducing an impact factor into the simulation analysis in the evaporative supercooling process.Meanwhile, experiments are carried out by adopting the particle analyzer to detect the radii and the velocities of the droplets, and an infrared camera to examine the temperature profile of the physical process.It is found that the theoretical conclusion agrees well with the experimental results.Compared with the conventional system, the new system can alleviate the burden on electric power and raise efficiency.These improvements are essentially attributed to the reutilization of the inner waste heat generated from the system itself.
