Simple enough. acts as food storage, converts water into ice blocks over time, cools reactor components manually, probably other things people can figure out. As for crafting, a compressor and a personal safe, (and possibly a chip) produces 2 (?) refrigerator blocks. stacking these two refrigerator blocks creates an upright fridge. maybe 3 placed side-by-side makes a chest freezer. EU draw should depend on what you are doing with it. i'd say set it up with an internal thermostat and different interactions affect the internal temperature. The thermostat could be adjustable as well. 5-10 eu/t when running, overclockers allow you to cool it faster and colder. Cold beer anyone?
