Freezing doesn't hurt whole roasted coffee beans.
What hurts roasted coffee beans (ground or whole) is humidity.
Coffee beans are roasted at high temps so they do not need any protection from storing at room temperature because whatever was unstable at room temperature is destroyed during the roasting process. The roasting process makes the distinctive taste of coffee. Green unroasted beans taste quite bland.
Roasted coffee is very porous (like activated carbon) so it will pick up humidity and smells very easily which can give off-flavours to a fine and delicate roasted coffee.
What is very important is storing in a well sealed jar. I have a 1 L mason jar with a wire attachment and rubber seal. I freeze whole beans and take out 1/2 cup at a time to fill my coffee mill (last almost a week). I freshly mill for every batch.
