eli5: I’ve seen some yt short about having freezers in research stations on Antarctica that are constantly kept at -20°C where the outside is -70°C, how do those freezers work? Are they in this situation just a heater that keep the room at -20°C or something else?

Wouldn’t it have something to do with the compression cycle of whatever gas it uses?

outside is very cold. Inside is very warm. The refrigerator pulls the warm air from inside and turns it into colder air, but not as cold as outside. It is used for food storage probably or something similar.
