When a refrigerator has been turned on for some time, steady state refrigeration occurs. This is the normal refrigerator operative state. But what exactly happens?
These things are really hard to do research on, since Internet searches, regardless of search query detailing, result in a lot of useless sites. Our textbook, University Physics 11th Ed., has nothing on the subject.
Does the compressor
1. lower its amount of work done on the refrigerant so much, that the refrigerator cools as quickly as heat conduction heats the food? (I don't think so)
2. lower its amount of work for some time, when the temperature gets a bit too cool, then increase it, when the temperature gets a bit too hot, and continue this way, steadily lowering and increasing its work? (This has been suggested to us)
3. reverse the process for some time (so that heat is pumped into, instead of out of the refrigerator) and continue steadily reversing the process? (This too has been suggested)
