Abstract:
In order to improve the timeliness and economy of the design of life support system of movable refuge chamber,the numerical method is used to study the effect of the number and arrangement of the refrigeration-purity machine on flow characteristics and comfort of a certain type of refuge chamber.A 3-D simulation model is developed by FLUENT based on the finite volume method.The velocity field and temperature field under different conditions are studied.The comfort of the chamber is evaluated.The simulation results show that the double refrigeration-purity machine system can meet the requirements of the flow characteristics and the comfort.This work can provide some foundation for the model selection and arrangement of the facilities in the refuge chamber.
