This paper analyzed the configuration and use features of vacuum thermal isolation plate. Structure of compound isolator was given. It described vacuum thermal isolation plate and isolation layers distribution which were used in our refrigerator BCD-186CHS, and also compared performance between polyurethane and compound thermal isolation, heat loss, and energy consumption of these two materials applied to refrigerator. The experimental result shows that heat loss is saved by 12. 6% and energy consumption is saved by 11.4% when compound isolation is used. This paper put forward application modes, cautions, and the effect of use ＇of vacuum thermal isolation plate in refrigerator. The prospect of vacuum thermal isolation plate was described.
