I have a container with three layers of different materials, How can predict the time of cooling that container if the external temp is 32 degree and internal temperature suppose to be 2 degree or less. How the boundary conditions will be if the container is rectangular in shape

To predict the time of cooling for a container with three layers of different materials and a rectangular shape, you will need to consider the heat transfer processes occurring through conduction, convection, and radiation. The boundary conditions will depend on the specific characteristics of your system.
Establish the boundary conditions: Define the external temperature as 32 degrees Celsius and the desired internal temperature as 2 degrees Celsius or lower. These temperatures will serve as the boundary conditions for the cooling process. Additionally, consider the initial temperature of the container before cooling starts. Apply the appropriate heat transfer equation for each layer of the container. The most common equation for heat conduction in rectangular solids is Fourier's law.
Hope this answers your question.

Am using Ansys 2021R2 I want to predict time taken to cool a container with three layers, Outer layer Galvanized sheet of 1.5m, between layer polyurethane foam of 60mm and inner layer aluminum of 1mm. The container is surrounded by evaporator using compression vapour system. If the surrounding is 32 degree and inner is 2degree.
In the above figure you can see looking as on layer but in the reality there are three layers as explained. So during setup in boundary condition how these three layers can be presented using figure above?
How ANSYS can assist me on that case
