Aiming at the passive temperature control problem in confined spaces
we investigate the heat transfer and thermodynamic characteristics of module type ice temperature control process with mathematical models and experiments. A model for phase transition refrigeration by cool storage module is established
and with the mathematical expression for wall heat transfer coefficient
effective cooling time and cooling rate are derived. The relative error between the theoretical effective cooling time and experimental one is less than 5%. The results indicate that the wall heat transfer coefficient and cooling rate are proportional to environment temperature and relative moisture
and inversely proportional to cooling time. The correction factor equation for environment temperature and moisture is established and utilized for revising the mathematical models of storage module cooling rate and effective cooling time. These results provide important reference to the application of passive phase-transition refrigeration in confined space.
