Imagine a perfectly thermally isolated room at 70 degrees Fahrenheit. A normal refrigerator that has some reasonable efficiency is brought into the room. It keeps the air inside of it at around 50 degrees or so. Will the room become warmer or colder? I think colder because the refrigerator will cool down the room more than the thermal energy it makes will warm the room.
