Numerical simulation of temperature and velocity field was taken on a freezer based on PHONEICS code. The physical and mathematical models were established by suitable geometric simplifying. The different inlet velocity and inner fence of freezer were compared and analyzed. The research shows that inlet velocity, production output, the energy consumption and their match are important factors which affect the freezing time. The addition of fence can improve the production output, and detract the energy consumption
