Consumer fridges also consume a lot more energy in the interest of keeping humidity (and, subsequently, frost) out of the compartment. They also run defrost cycles with heaters to keep the evaporators from icing over and locking up the system. That lack of humidity control is what builds up a secondary layer of insulating frost/ice inside a normal chest freezer. It results in that "cleaning flow" of water inside the chest fridge, which doesn't sound as sanitary or healthy as the author proclaims once it builds up to a significant level. "The amount of condensation depends how much moisture is in the ambient air and how often and how vigorously we open and close the fridge lid." Wait. I thought less to no ambient air mixed into a chest fridge cavity according the author.
