Usage

The Fridge and Freezer are separate block types but will connect if the freezer is placed on top of the fridge. The fridge serves as storage with 54 slots in it. The freezer has its own recipe type, allowing you to do things such as creating blue ice from packed ice, and then packed ice from ice, or leather from rotten flesh. It uses cold things such as snow, snow layers, or ice as a coolant.

There's also an iron fridge, it's functionality is the same but the freezer here must be at the bottom.

Fridges placed on top of each other will also stack and connect.

Crafting

To craft the fridge you will need a chest and some of the material which is iron or concrete. For the freezer you need the base material and 2 redstone dust.
