Abstract: The transparent drawers of refrigerator freezer are mostly made of general purpose polystyrene (GPPS). Although the material has high transparency, it has poor toughness and is easy to crack and damage. In the process of users' use, if there is accumulated water in the drawer, the external force will be produced by freezing at low temperature, which will easily lead to the drawer cracking and affect the user's experience. By simulating the use scenarios of drawers in air-cooled and direct cooled refrigerators, the effects of various factors on the freezing and cracking of drawers are analyzed. In order to improve the reliability of the refrigerator drawer, it is suggested that the general polystyrene drawer should be used in the refrigerator.

Key words: Refrigerator drawer, Freezer, Icing
